I am trying to add an image to a button (C# Winform, VS2010). I have added the resource by Adding Existing Item in the Resources.resx file. I then assign my image to the button and all appears well. When i run my program i get:
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
Additional information: Could not load file or assembly 'BmsReplayAnalysis.resources, Version=1.0.0.0, Culture=en-US, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
in this code:
public static System.Drawing.Bitmap play1 {
get {
object obj = ResourceManager.GetObject("play1", resourceCulture); <-- DIES HERE
return ((System.Drawing.Bitmap)(obj));
}
}
Can anyone tell me what i am doing wrong?
When you just give it a name of a file, when you run it, it looks for it in the folder that it is running out of. If you are running in debug mode, it will look for play1 inside the debug folder. if its not there its an error.

In my codebase, I have created a container sucessfully, but then run into an exception when trying to configure it:
_container = new UnityContainer();
var unityConfigurationSection = (UnityConfigurationSection)ConfigurationManager.GetSection("unity");
if (unityConfigurationSection != null)
{
try
{
unityConfigurationSection.Configure(_container);
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
}
the unityConfigurationSection.Configure(_container); line is what does me in. I get:
The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
It looks like there's a type that can't be resolved from its name, judging from the stack trace.
But how do I figure out what type?
The exception indicates that the name of the assembly that was requested is in some way not able to be parsed and looked up. If the assembly name was valid but it just wasn't found you'd get a different error.
Usually the message of the exception includes the assembly that failed to resolve.
For instance, this code throws the exact exception:
var asm = Assembly.Load("test,,;''");
This is obviously not a valid assembly name, so you get:
System.IO.FileLoadException: 'Could not load file or assembly '"test\,\,;''"' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)'
I'd debug the code and see if you can get to the message of the exception.
One thing I'd try is to go into Tools -> Options -> Debugging -> Enable Just My Code and remove the check mark. This should let you see the unwrapped exception that gets thrown when Unity tries to resolve the dependency.
Another quick approach would be to handle the AssemblyResolve Event. Whenever an assembly that was looked for by name fails to resolve for whatever reason that Event is invoked. The args parameter contain the name of the assembly that was tried to be resolved.
Put this as the first line in your Program:
AppDomain.CurrentDomain.AssemblyResolve += Resolver;
and then put this method into the same class:
private static Assembly Resolver(object sender, ResolveEventArgs args)
{
string assemblyName = args.Name;
throw new Exception(args.Name);
}
Now you can set a breakpoint and check out the name of the assembly that tried to get resolved.
I try to use Sikuli Integrator for C#.
I create new project in Visual Studio 2015, and I Install SikuliIntegrator.
After the installation JSikuliModule.jar, it will be part of my solution, together with some additional files. After that Properties to set “Copy to Output Directory” property to “Copy always” of JSikuliModule.jar
and then I try my code :
class Program
{
static void Main(string[] args)
{
String pattern = #"C:\\Users\\amin-\\Documents\\Visual Studio 2015\\Projects\\SikuliTest\\SikuliTest\\img\\logo.png";
SikuliAction.Click(pattern);
//if (SikuliAction.Exists(pattern).IsEmpty)
//{
// Console.WriteLine("Nope! It's gone...");
//}
//else
//{
// Console.WriteLine("Yep! It's there...");
//}
}
}
If I run the code, this is the errors shows :
An unhandled exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll Additional information: Access to the path 'C:\SikuliOutputLog.txt' is denied.
If I run the code as an administrator, this is the errors shows :
An unhandled exception of type 'System.Exception' occurred in SikuliModule.dl Additional information: ###FAILURE
Manually create a text file 'C:\SikuliOutputLog.txt' then run the code.
It works for me.
In Windows10 besides manually adding C:\SikuliOutputLog.txt you need also to make sure current user have the 'Write' control to this file.
During testing of a command line based program I delibrately removed a DLL from the execution directory. This of course caused the Could not load file or assembly exception to trigger when the program started, and dumped the raw exception details onto the command line:
Unhandled Exception: System.IO.FileNotFoundException: Could not load
file or assembly 'MyDLL, Version=1.2.3.14056, Culture
=neutral, PublicKeyToken=0a0932194e205074' or one of its dependencies. The system cannot find the file specified. at
MyApp.Program.Program.Main(String[] args)
I don't want the user to see these raw details, but I can't see how/where to catch this exception in order to sanitize the presented message.
So what is the best/accepted way to catch something like this?
You can register to the Unhandled Exception handler and treat it like so:
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler((x, y) =>
{
var exception = y.ExceptionObject as Exception;
if (exception is System.IO.FileNotFoundException)
Console.WriteLine("Please make sure the DLL is in the same folder.");
});
Make sure this event registration is executed before any reference to MyDLL in your code. A static constructor in Program.cs might be a good option.
Is there a way to persist CS-Script internal assembly cache between subsequent application's runs?
Used component: http://www.csscript.net/
The desired behavior is:
when I compile an assembly form a script string and I close the application, the next time I run the application the compiled assembly with matching script string is found and no recompilation is needed.
This question is follow-up of another question:
Is there a way to call C# script files with better performance results?
Here is my code, but every script string requires recompilation with every restart of parent .NET application.
public interface ICalculateScript
{
Exception Calculate(QSift qsift, QSExamParams exam);
}
...
void Calculate(string script)
{
CSScript.CacheEnabled = true;
//Can following command use built-in cache to load assembly, compiled by this line of code, but by another instance of this app which run in the past and has been meanwhile closed?
Assembly assembly = = CSScript.LoadCode(script, null);
AsmHelper asmHelper = new AsmHelper(assembly);
ICalculateScript calcScript = (ICalculateScript)asmHelper.CreateObject("Script");
calcScript.Calculate(this, exam);
}

I got an answer fom Oleg Shilo which pointed me in the right direction:
The cache folder indeed grows as new scripts are compiled/loaded. This
is the nature of the caching. It seems that it "grows without control"
though it is not. Once cache is created for a given script file it is
never duplicated and the new cache update is always written over the
existing one.
The problem in your case is that every time you load the file you give
it a unique name thus you are creating a new unique cache. To fix it
you need to start using the same name for the script file every time
you load/execute it.
Alternatively you can completely take over the caching location and
specify what ever cache name you want. It is that second parameter
that you pass null for:
Assembly assembly = CSScript.LoadCode(script, null);
I used following code:
if (assemblyFileName == null)
assembly = CSScript.LoadCode(script, null); //In case there is no name specified - when my custom temp folder cannot be created etc.
else
assembly = CSScript.LoadCode(script, assemblyFileName, false, null); //Specify full path and file name with extension
Thanks to this I have complete control over cached assembly name and location.
If cached assembly with appropriate script already exists, I can simply load it instead of compiling a new one:
Assembly assembly = Assembly.LoadFrom(assemblyFileName);
AsmHelper asmHelper = new AsmHelper(assembly)
The speed of initial loading is better and there is no uncontrollably growing cache.
I have the lines of code shown below
Can anybody provide me the code which will create type value as shown below
The exception I get is: " ex = {"Could not load file or assembly , Version=0.0.0.0, Culture=neutr..."
If you do have the file: _UNIX_Linux_TesterTEST-MACHINE.dll, then you should look for the libraries that this one depends on. One way to find out which they are is to run Fuslogw.exe(the Assembly Binding Log Viewer).
