I am very much interested in ILNUmerics and would like to try the free version, but I am having troubles.
I have started with a console application and was trying to run the 'hello ilnumerics'console application but I noticed that VS fails to find MKL libraries.
I am using VS2012 under Windwos 8 (through Bootcamp on a MacBook Pro mid 2010; should it be relevant); I have installed the NuGet Packages extension from the Project solution. Then right-click on references in the solution explorer, 'Manage Nu Get Packages', fron online/search found ilnumerics in various versions. I chose 'ILNumerics' and install. I got 'ILNumerics' and 'ILNumerics.Native' added to my project. Then I can see ILNumerics under 'References' in Solution Explorer and also get two new folders /bin32/ and /bin64/ they both contain two DLLs named: libiomp5md.dll and mkl_custom.dll. I have checked their
'Copy to Ouput Directory' property and they are all set to 'Copy if newer'.
Apparently mkl_custom is not found. I write the following code, taken from the quickstart guide:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ILNumerics;
namespace ConsoleApplication3
{
class Program : ILMath
{
static void Main(string[] args)
{
ILArray<double> A = array<double>
(new double[] { 1,1,1,1,1,2,3,4,1,3,6,10,1,4,10,20} ,4, 4);
ILArray<double> B = counter(4, 2);
ILArray<double> Result = linsolve(A, B);
Console.Out.WriteLine("A: " + Environment.NewLine +
A.ToString());
Console.Out.WriteLine("B: " + Environment.NewLine + B.ToString());
Console.ReadKey();
}
}
}
and I get this exception:
An unhandled exception of type 'System.DllNotFoundException' occurred in ILNumerics.dll
Additional information: Unable to load DLL 'mkl_custom': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
If I do not invoke linsolve the ToString method of ILArray does work: if I comment // ILArray Result = linsolve(A, B);
I get the two matrices printed on the screen.
I have also tried to compute the determinant of a matrix and got the same exception: apparently any time I call mkl_custom VS is not capable to find it.
Any help/hint, please?
Also, is it necessary to install ILNumerics through NuGet on any project added to the solution? Would it be possible to install it locally once for all and then add the reference if necessary?
Two options:
1) Make sure, all binaries are accesible as intended: ILNumerics uses AnyCPU targets and chooses the platform dependend subfolder by adding the "bin32" / "bin64" directories to the PATH envoronment variable on startup. Possibly there is something failing on your machine? You can make sure by placing the correct binaries (depending on your platform) directly into the output path manually.
2) In case the error persists: mkl_custom.dll depends on some other dlls itself. One (libiomp5md.dll) is delivered with the ILNumerics nuget package. Others are expected to exist on your system: KERNEL32.DLL and MSVCR110.DLL. Make sure, you have these! If the kernel dll was missing -> call it a miracle and reinstall your system. If the msvcr110 is missing -> go here and install the "Visual C++ Redistributable for Visual Studio 2012".
In case the problem persists, you may file a bug on the ILNumerics bugtracker, because, the runtime should be there, as you wrote you are using VS2012. Possibly it is a versioning problem though.
EDIT: Since version 4.0 ILNumerics does not deploy the native binaries in bin32/ bin64/ subfolder anymore but installs all native dependencies systemwide into the GAC and System32/WOW folders. The old scheme will still work (for compatibility with old projects) though. But it is not necessary anymore to deal with any dependancies for ILNumerics explicitly. They should simply be found at runtime.
Like numbers303 said, ILNumerics.dll can't find a required dependency. You can brute force fixing this dependency by copying the required DLLs to the same directory as the ILNumerics.dll as a post build step, but I think there's a more elegant solution.
A VS2010 .NET console solution gets created by default with the x86 configuration. Compiling and running the ILNumerics example Hello ILNumerics! code with this configuration results in a DLL not found exception (mkl_custom.dll).
Re-targeting the solution via configuration manager to 'Any CPU' fixed the issue for me:
In Solution Explorer, right click on the solution and select properties. Select Configuration Properties and click on the Configuration Manager... button in the upper right hand corner. Make sure that the project that uses ILNumerics has the 'Any CPU' selected. If 'Any CPU' isn't available as a selection, select '' from the pulldown and create an 'Any CPU' platform based on your current platform. Usually this just means accepting the default in the 'New Project Platform' dialog. You'll probably also want to modify the 'Active solution platform:' to contain an 'Any CPU' target as well.
Rebuild/run.
In my case it helped to install "Visual C++ Redistributable for Visual Studio 2012" although I work with Visual Studio 2010 with the corresponding "Visual C++ Redistributable for Visual Studio 2010" installed. Which worked fine as long as the mkl_custom.dll is not needed. But colleagues of mine dosn't have this problem without having the 2012 Redistributable installed.

I have a C# WPF application. It uses a small commercial framework (https://www.inosoft.com/en/product/product-features/).
I'm building this application both locally and via a buildserver (Azure pipelines). I use a marketplace task to change the assemblyinfo.cs before building: https://marketplace.visualstudio.com/items?itemName=bleddynrichards.Assembly-Info-Task
The build server executes the following tasks:
NuGet restore
Inject/Edit assemblyVersion, AssemblyFileVersion and AssemblyInformationalVersion with the right version info
Build
Now when I run this application, it starts up and runs for a while.
Quickly after starting I hook the VS debugger into the process.
Then all of the sudden the application crashes:
This is weird, because when I build locally, this runtime error does not occur.
Note that i set all properties to the same values for testing:
AssemblyVersion: 1.2.3.4
AssemblyFileVersion: 5.6.7.8
AssemblyInformationalVersion: 9.10.11.12
I then use Telerik justAssembly to compare the build output from my local build and the buildserver:
As we can see the local output (on the left) does not have a version added to the Application.LoadComponent(..) whilst the build server output (on the right) does.
public void InitializeComponent()
{
if (!this._contentLoaded)
{
this._contentLoaded = true;
Application.LoadComponent(this, new Uri("/HmiMetis;component/views/app.xaml", UriKind.Relative));
}
}
This means that this is the root cause of the runtime exception.
I find it weird that the build process on my local machine differs from the build server output. Both (should) use visual studio 2017 to build. Why does the buildserver add the version to the uri of loadComponent and my local machine does not?
Anyways, I need this exception gone.
Therefore I think the easiest way would be to force the buildserver to not add the version information under any circumstances. Is this possible and how?
Edit:
I Found a relating issue report that may have something to do with this:
https://github.com/dotnet/core/issues/3189
I've been using TuesPechkin for some time now and today I went to update the nuget package to the new version 2.0.0+ and noticed that Factory.Create() no longer resolved, so I went to read on the GitHub the changes made and noticed it now expects the path to the dll?
IConverter converter =
new ThreadSafeConverter(
new PdfToolset(
new StaticDeployment(DLL_FOLDER_PATH)));
For the past few hours I've tried almost all the paths I can think of, "\bin", "\app_data", "\app_start", etc and I can't seem to find or figure out what it wants for the path and what dll?
I can see the TuesPechkin dll in my bin folder and it was the first path I tried, but I got the following error:
Additional information: Unable to load DLL 'wkhtmltox.dll': The
specified module could not be found. (Exception from HRESULT:
0x8007007E)
Where is that dll and now can I get it as the library doesn't seem to contain it, I tried installing the TuesPechkin.Wkhtmltox.Win32 package but the dll still is nowhere to be found. Also I am using this in a asp.net website project so I assume that using the following should work for obtaining the path, right?
var path = HttpContext.Current.Server.MapPath(#"~\bin\TuesPechkin.dll");
Further information: https://github.com/tuespetre/TuesPechkin/issues/57
The Tuespechkin has a zip file as a resource in the Win32 and Win64 embedded packages for the 'wkhtmltox.dll' file.
What it does when you use the Win32 or Win64 Embedded package is unzips the file and places it in the directory that you specify.
I have been putting a copy of the wkhtmltox dll at the root portion of my web app directory and pointing the DLL_FOLDER_PATH to it using the server physical path of my web app to get to it.
According to the author, you must set the converter in a static field for best results.
I do that, but set the converter to null when I am finished using it, and that seems to work.
Tuespechkin is wrapper for the wmkhtmlox dll file.
The original file is written in C++ and so will not automatically be usable in C# or VB.NET or any of the other managed code domains.
The Tuespechkin.dll file DOES NOT contain a copy of 'wkhtmltox.dll'. You either have to use one of the other embedded deployment modules or install a copy of the 'wkhtmltox.dll' in your web app after downloading it from the internet. That is what I do, and it seems to work just fine.
I am using Team Foundation Server, and attempts to compile code after using the Tuespechkin routines will fail the first time because the 'wkhtmltox.dll' file gets locked, but all you have to do is simply retry your build and it will go through.
I had issues with the 32-bit routine not working in a 64-bit environment and the 64-bit environment not being testable on localhost. I went with the workaround I came up with after examining the source code for Tuespechkin and the Win32 and Win64 embedded deployment packages.
It works well as long as you specify a url for the input rather than raw html.
The older package didn't render css very well.
If you are using a print.aspx routine, you can create the url for it as an offset from your main url.
I don't have the source code I am using with me at this point to offset to your base url for your web application, but it is simply an offshoot of HttpRequest.
You have to use the physical path to find the .dll, but you can use a web path for the print routine.
I hope this answers your question a bit.
If you are getting this error -> Could not load file or assembly 'TuesPechkin.Wkhtmltox.Win64' or one of its dependencies. An attempt was made to load a program with an incorrect format.
In Visual Studio Go to -
Tools -> Options -> Projects and Solutions -> Web Projects -> Use the 64 bit version of IIS Express for web sites and projects.
I installed TuesPechkin.Wkhtmltox.Win64 Nuget package and used the following code in a singleton:
public class PechkinPDFConvertor : IPDFConvertor
{
IConverter converter =
new ThreadSafeConverter(
new RemotingToolset<PdfToolset>(
new Win64EmbeddedDeployment(
new TempFolderDeployment())));
public byte[] Convert(string html)
{
// return PechkinSync.Convert(new GlobalConfig(), html);
return converter.Convert(new HtmlToPdfDocument(html));
}
}
The web application then has to be run in x64 otherwise you will get an error about trying to load an x64 assembly in an x86 environment. Presumably you have to choose x64 or x86 at design time and use the corresponding nuget package, it would be nicer to choose this in the web.config.
EDIT: The above code failed on one server with the exact same message as yours - it was due to having not installed VC++ 2013. So the new code is running x86 as follows
try
{
string path = Path.Combine(Path.GetTempPath(), "MyApp_PDF_32");
Converter = new ThreadSafeConverter(
new RemotingToolset<PdfToolset>(
new Win32EmbeddedDeployment(
new StaticDeployment(path))));
}
catch (Exception e)
{
if (e.Message.StartsWith("Unable to load DLL 'wkhtmltox.dll'"))
{
throw new InvalidOperationException(
"Ensure the prerequisite C++ 2013 Redistributable is installed", e);
}
else
throw;
}
If you do not want run the installer for wkhtmltox just to get the dll, you can do the following:
As #Timothy suggests, if you use the embedded version of wkhtmltox.dll from TuesPechkin, it will unzip it and place it in a temp directory. I copied this dll and referenced it with the StaticDeployment option without any issues.
To find the exact location, I just used Process Monitor (procmon.exe). For me it was C:\Windows\Temp\-169958574\8\0.12.2.1\wkhtmltox.dll
In my case, I am deploying on a 64-bit VPS then I got this error. I have solved the problem by installing the wkhtmltopdf that I downloaded from http://wkhtmltopdf.org/downloads.html. I chose the 32-bit installer.
In my case, I have solved the problem by installing the Wkhtmltox for win32 at https://www.nuget.org/packages/TuesPechkin.Wkhtmltox.Win32/
This error: Unable to load DLL 'wkhtmltox.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) is returned in two situations:
1- Deploy dependency not installed:
For solve this, you can install nuget package "TuesPechkin.Wkhtmltox.Win64" and use this code (for WebApplications running in IIS):
IConverter converter =
new ThreadSafeConverter(
new RemotingToolset<PdfToolset>(
new Win64EmbeddedDeployment(
new TempFolderDeployment())));
// Keep the converter somewhere static, or as a singleton instance!
// Do NOT run the above code more than once in the application lifecycle!
byte[] result = converter.Convert(document);
In runtime this code will copy the dependency "wkhtmltox.dll" in a temporary directory like: "C:\Windows\Temp\1402166677\8\0.12.2.1". It's possible to get the destination of file using:
var deployment = new Win64EmbeddedDeployment(new TempFolderDeployment());
Console.WriteLine(deployment.Path);
2- Microsoft Visual C++ 2013 Redistributable not installed:
As described here:
https://github.com/tuespetre/TuesPechkin/issues/65#issuecomment-71266114, the Visual C++ 2013 Runtime is required.
The solution from README is:
You must have Visual C++ 2013 runtime installed to use these packages. Otherwise, you will need to download the MingW build of wkhtmltopdf and its dependencies from their website and use that with the library. https://github.com/tuespetre/TuesPechkin#wkhtmltoxdll
or, you can install the Microsoft Visual C++ 2013 Redistributable:
choco install msvisualcplusplus2013-redist
Here is AnyCpu version, also support iis-base or winform application
using TuesPechkin.Wkhtmltox.AnyCPU;
...
var converter = PDFHelper.Factory.GetConverter();
var result = converter.Convert(This.Document);
Reference : https://github.com/tloy1966/TuesPechkin
Installing the Visual C++ Redistributable for Visual Studio 2013 resolved the error for me.

From C# code I'm trying to retrieve all the namespaces from powershell... (Later more complex things, like creating namespaces)
PowerShell ps = PowerShell.Create();
ps.AddCommand("Import-Module").AddArgument("ServiceBus").Invoke();
var result = ps.AddCommand("Get-SBNamespace").Invoke();
Above code gives the following exception:
The 'Get-SBNamespace' command was found in the module 'ServiceBus',
but the module could not be loaded. For more information, run
'Import-Module ServiceBus'.
Does anyone know how to solve this error?
CURRENT STATUS: after some debugging I've found that no modules are loaded by default in the PowerShell object. Using the code:
InitialSessionState iss = InitialSessionState.CreateDefault();
iss.ImportPSModule(new string[]{#"serviceBus"});
PowerShell ps = PowerShell.Create(iss);
doesn't work to load the service bus module. Also the code:
ps.AddCommand("Import-Module").AddParameter("-Name", "serviceBus").Invoke();
doesn't work to import the service bus module. Running Visual Studio in administrator mode also doesn't make a difference
Thanks in advance
You didn't say which version of Visual Studio you're using. If it's VS 2012, when you tried the x64 platform target did you make sure that "Prefer 32-bit" was not checked? Even if it was not checked try checking it, saving the project configuration, clearing it and saving again - this worked for me on another project.
UPDATE
It's been suggested elsewhere that there's a bug in VS2012 that shows "Prefer 32-bit" as greyed-out and unchecked when it's actually active. I'm running Update 2 and I don't see that. But it sounds like you might be. I suggest you edit the .csproj file directly.
Whilst "Platform Target" is set at "Any CPU", in Solution Explorer, right-click on the Project name (or, with go to the PROJECT menu) and select "Unload Project". Project files will close and Solution Explorer will display project name (unavailable) > The project file was unloaded:
Right-click on the Project name again and select "Edit project name.csproj". The file is XML and mostly comprises PropertyGroup and ItemGroup elements. In a console project, the first PropertyGroup usually contains a Platform element which should read AnyCPU if you followed my instructions above. The next two PropertyGroups are normally for Debug and Release configurations. If you've added another configuration, it will have its own PropertyGroup. In each of these, look for an element which reads:
<Prefer32Bit>true</Prefer32Bit>
What you should have is an element which reads:
<Prefer32Bit>false</Prefer32Bit>
Either change it or insert it (in each configuration ProjectGroup), save the file and close it. Back in Solution Explorer, right-click the project and select "Reload Project". Let me know if that solves it. You can confirm your PowerShell is now running 64-bit by get the result of
[System.IntPtr]::Size
e.g.
ps.AddScript("[System.IntPtr]::Size");
which will be 4 in an x86 process and 8 in an x64 process.
Which my project set up like this, I was able to load ServiceBus using:
ps.AddCommand("Import-Module").AddArgument("ServiceBus");
Hopefully, you will, too.
I don't have ServiceBus installed so I can't verify exactly what you've tried but
ps.AddCommand("Import-Module").AddArgument("ActiveDirectory").Invoke();
worked for me, so your original syntax looks good.
Just to test for failure, I tried:
ps.AddCommand("Import-Module").AddArgument("CheeseDirectory");
ps.Commands.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
var importResult = ps.Invoke();
foreach (PSObject result in importResult)
{
Console.WriteLine(result);
}
and got
The specified module 'CheeseDirectory' was not loaded because no valid
module file was found in any module directory.
Have you tried similar?
Do you take care of your Assembly target in your C# program (x86 versus X64). The module may exist in one target, not in the other. PowerShell exists in both.
Seems you're trying to import some modules and execute the cmdlet or function inside the module, right?
So I think you could try the following code:
PowerShell ps = PowerShell.Create();
Assembly ass = Assembly.LoadFile(#"yourServiceBus.dll");
ps.AddCommand("Import-Module").AddParameter("Assembly", ass).Invoke();
var result = ps.AddCommand("Get-SBNamespace").Invoke();
Hope this could help.
I am trying to build SparkleShare on Mac.
I have Mac OS 10.6
SparkleShare claims to run on Snow Leopard (10.6) or later
SparkleShare contains calls to NSUserNotification, a class which is Available in OS X v10.8 and later
Monodevelop throws an error:
error CS0246: The type or namespace name `NSUserNotification' could not be found. Are you missing a using directive or an assembly reference?
In Monodevelop, when I begin typing MonoMac.Foundation.NSUser, the only suggested item is NSUserDefaults, NSUserNotification is not suggested.
Is this kind of cross-compilation possible?
I can't upgrade to 10.8 because I also want to check how the user experience is on 10.6.
Run:
git clone https://github.com/mono/monomac
git clone https://github.com/mono/maccore
cd monomac
make
It should generate MonoMac.dll. Copy it to wherever your MonoMac.dll is, restart Monodevelop, the project should now build fine.
I just had a look at MonoMac's source code, and NSUserNotification is a recent addition, it has been added three months ago: https://github.com/mono/monomac/commit/2c4a8c639254705e0dde1ce32f4e49cfcb72187e.
These are the generated files:
NSUserNotification.g.cs
NSUserNotificationCenter.g.cs
NSUserNotificationActivationType
NSUserNotificationCenterDelegate.g.cs
As a workaround for older MonoMac versions, you can simply copy these into your code.
I used IBM.Data.DB2 version=9.7.4.4 and everything worked perfectly.
But I couldn't use a performance profiler and the support told me I should try
with new IBM version = 10.1. I installed it and had problems at first. I had to register a reference to it in GAC, etc.
Now to my question: If I browse to C:\Program Files\IBM\SQLLIB\BIN\netf40_32\IBM.Data.DB2.dll
and look properties I have version: 10.1.0.4 but when I add reference in visual studio
I have version = 9.7.4.4 in the property window and I am not sure if the right version is used.
How do I get
the right version into property window in visual studio?
I solved this problem by using the IBM.Data.DB2.dll from C:\Program Files\IBM\SQLLIB\BIN\netf40_32\specific\IBM.Data.DB2.10.1.0.dll.
So I got the right version, then I had SQL1159 initialization error with db2 .net data provider reason code 2. The db2app.dll was searched in wrong directory (File not found: http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp?topic=/com.ibm.db2.luw.messages.sql.doc/doc/msql01159n.html)
I reinstalled the db2 client and now it works...
