C# Label printing with p-Touch Brother Error: System.IO.FileNotFoundException

I'm trying to write a program that changes and prints an existing label "label.lbx" from a p-Touch Brother printer.
But my program stops at:
bpac.Document doc = new bpac.Document();
The error message:
**System.IO.FileNotFoundException:** "The COM class directory for the component with CLSID {B940C105-7F01-46FE-BF41-E040B9BDA83D} could not be retrieved due to the following error: 8007007e The specified module was not found. (HRESULT exception: 0x8007007E).
I have already removed and added the Interop.bpac.dll file. Project cleaned up and rebuilt. Moved the file to the Debug Order. But it didn't help.
Does anyone have an idea why the error message is coming?
My Code:
string path = #"C:\Users\source\repos\LabelTool\label.lbx";
bpac.Document doc = new bpac.Document();
doc.Open(path);
doc.SetPrinter("Printer", true);
doc.GetObject("ReplacePlace").Text = textBox1.Text;
doc.StartPrint("", bpac.PrintOptionConstants.bpoDefault);
doc.PrintOut(1, bpac.PrintOptionConstants.bpoDefault);
doc.EndPrint();
doc.Close();

I was able to solve the problem. For those who have the problem, try the following.
First of all you need the 32 bit version. Then it should work on your computer.
Next you have to pay attention that the dll file is always created with a release.
I had to change from "Any CPU" to "x86". And:
Reference --> selection of the dll file in my case (Interop.bpac)-->
below in properties: Embed interopt types = False ; Local copy= True
See picture
The code then changes:
using bpac;
...
string path = #"C:\Users\source\repos\LabelTool\label.lbx";
bpac.Document doc = new bpac.Document();
doc.Open(path);
doc.SetPrinter("Printer", true);
doc.GetObject("ReplacePlace").Text = textBox1.Text;
doc.StartPrint("", bpac.PrintOptionConstants.bpoDefault);
doc.PrintOut(1, bpac.PrintOptionConstants.bpoDefault);
doc.EndPrint();
doc.Close();
Hope this helps some of you and saves you the trouble of troubleshooting.

asp.NET c# : Code working as a console app but not as a web app

My basic problem was converting a .docx file to .pdf. The problem would be solved incase I was allowed to use Microsoft.Office.Interop.Word.dll, which i am not since the server will not have MS Office installed. So I needed a free/open-source library that would allow me to do so. And i came across docx4j.NET.
http://www.docx4java.org/blog/2014/09/docx-to-pdf-in-c-net/
This worked fine as long as I ran it as a Console App. The following is the concerned code snippet:
string fileIN = #"C:\Users\...\Visual Studio 2013\Projects\HRDapp\HRDapp\Letter_Templates\AP.docx";
string fileOUT = #"C:\Users\...\Visual Studio 2013\Projects\HRDapp\HRDapp\Letter_Templates\AP.pdf";
log.Info("Hello from Common Logging");
// Necessary, if slf4j-api and slf4j-NetCommonLogging are separate DLLs
ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.slf4j.impl.StaticLoggerBinder)));
// Configure to find docx4j.properties
// .. add as URL the dir containing docx4j.properties (not the file itself!)
Plutext.PropertiesConfigurator.setDocx4jPropertiesDir(projectDir + #"src\samples\resources\");
java.io.File file = new java.io.File(fileIN);
// OK, do it..
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(file);
java.io.FileOutputStream fos = new java.io.FileOutputStream(new java.io.File(fileOUT));
org.docx4j.Docx4J.toPDF(wordMLPackage, fos);
fos.close();
In case of using this in a Web App, the code runs fine till
java.io.File file = new java.io.File(fileIN);
and gets stuck at
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(file);
Although the file path is correct and works fine in the console app, but there seems something else that I am missing here. The log also prints upto the following statement-
iisexpress.exe Information: 0 : [INFO] org.docx4j.jaxb.Context - Using Java 6/7 JAXB implementation
.. and stops. Any kind of reply directing me to the source of the error will be very helpful. Thanks.

As Jeroen (of IKVM fame) has explained, when there is no main assembly (eg in an ASP.NET application), the IKVM class loader can't find your assembly when the code is trying to dynamically load a class.
So you'll want to add not just:
ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.slf4j.impl.StaticLoggerBinder)));
but also:
ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.slf4j.LoggerFactory)));
ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.docx4j.jaxb.Context)));

Passing file name with spaces to SPOOL command using SQL Plus gives SP2-0768 Illegral SPOOL command error

My sql file contains
`SPOOL &1;
//sql code to execute
SPOOL OFF;`
The sql file is executed using SQL Plus and SQL Plus is being called from C# code using Process.Start... Code snipped
`var m_StartInfo = new ProcessStartInfo();
m_StartInfo.FileName = "SQLPLUS.EXE";
m_StartInfo.CreateNoWindow = true;
m_StartInfo.UseShellExecute = false;
m_StartInfo.Arguments = String.Format("{0}\"{1}\" \"{2}\"", connectionString, sqlfile, sqlLogFileName);
m_Process = Process.Start(m_StartInfo);
Other code.....`
It works fine and the sqlplus log is created fine at sqlLogFileName location. However if the sqlLogFileName has spaces in between (say like "C:\My Application\log.txt"), then the log file is not created, instead gives the error SP2-0768 Illegal SPOOL command on SQL Plus window
Any suggestion how to resolve this? I am using Oracle 11GR2

You just have to surround your file name with double quotes.
Something like:
spool "Test with spaces.txt"
Or in your case with a parameter:
SPOOL "&1"
I think is best not to use spaces though, as #tvCa explained.
Side Note:
What StarPilot is refering to, I believe, is about the redirect a command output to a file, and that is why it didn't work when you tried to use it.
For example in command prompt you would write:
dir > dir.txt
And that saves the output of dir inside dir.txt.

Oracle software is designed to be used with directories not having whitespaces (which is an accepted standard in Linux/Unix, even though technically you can do otherwise). On Windows, things are different, but the Oracle software has the same idea : it does not like whitespaces. So, the fix is clear : spool to a directory without whitespaces. This is advice, anybody is free to take or not.

Microsoft Diagnostics Runtime crash.dmp analysis (C#)

I'm trying to read in a crash.dmp using the functionality in Microsoft.Diagnostics.Runtime .NET componenet (also known as ClrMD).
I have a crash.dmp in a known location (in a string called pathToFile) so that's not the issue. The rest of the code looks like this.
DataTarget dataTarget = DataTarget.LoadCrashDump(pathToFile);
ClrInfo clrInfo = dataTarget.ClrVersions[0];
string dacLocation = clrInfo.TryGetDacLocation();
When testing this code, I get the following error in the command window:
Error processing directory: System.ArgumentOutOfRangeException. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
I'm assuming it's something to do with the ClrVersions[0] bit but can't for the life of me pin it down.
Any help would be appreciated.
Current Status
When running the following command (which fails)
ClrRuntime rt = dataTarget.CreateRuntime("path\to\mscordawks.dll");
I receive the following error in cmd
mismatched architecture between this process and the dac
Cheers
Anyone?

If the TryGetDacLocation succeeded then you should be able to do
ClrRuntime rt = dataTarget.CreateRuntime(dacLocation);
so you get the correct dacLocation.
Was the dump you are analysing generated on same machine where you are analysing it?
Also what are the bitnesses of the process the dump was generated from, the process in which the CLRMD code is running and the debugger utility used to generate the dump?
Generally you want to be matching the bitnesses all round (x86/x64).
Doug

I was having the same issue reading a dump file generated on the same computer. There were two problems, first bitness (should have been 64, was running in 32) and the second harder problem that the proper DLL could not be located. To fix the second problem I created a method that tries all of the properly named DLLs it can find:
private static ClrRuntime GetRuntime(DataTarget target)
{
ClrInfo version = target.ClrVersions[0];
string dacLocation = version.TryGetDacLocation();
// If we don't have the dac installed, we will use the long-name dac in the same folder.
if (!string.IsNullOrEmpty(dacLocation))
dacLocation = version.DacInfo.FileName;
try // try the one it should be
{
return target.CreateRuntime(dacLocation);
}
catch (Exception e)
{
}
// can't find the one it should be, try'em all
string fileName = "mscordacwks.dll";
string[] searchLocations = new[]
{
#"C:\Windows\Microsoft.NET\",
#"C:\Windows\winsxs\"
};
foreach (string searchLocation in searchLocations)
{
foreach (string file in Directory.GetFiles(searchLocation, fileName, SearchOption.AllDirectories))
{
try
{
return target.CreateRuntime(file);
}
catch (Exception e)
{
}
}
}
throw new Exception("No found valid runtimes");
}

I followed this artificial to get the mscordacwks.dll when dealing with platform differences between where the dmp file was taken and the machine doing the analysis.
http://chentiangemalc.wordpress.com/2014/04/16/obtaining-correct-mscordacwks-dll-for-net-windbging/#comment-3380
and followed the steps including renaming the file to include the architecture and version information.
After that I just http://chentiangemalc.wordpress.com/2014/04/16/obtaining-correct-mscordacwks-dll-for-net-windbging/#comment-3380ut the full path of the file as dacLocation in the script.
After that it worked!
I suspect that putting it on the path could be made to work.

Gems with .NET Applications - How do I set up the Executables so they run without error?

I have a gem, roundhouse, which is an application compiled with .NET (C#). Runs on Windows and it should run in a 32 bit process.
To set up my gemspec, I set:
Gem::Specification.new do |s|
s.platform = 'mswin32'
s.name = 'roundhouse'
s.version = version
s.files = Dir['lib/**/*'] + Dir['bin/**/*']
s.bindir = 'bin'
s.executables << 'rh.exe'
When I install the gem, I should be able to type rh.exe from the command line at any path and it should run correctly.
In practice, I'm not seeing this work correctly. This is what I'm getting back:
Window has this for the header: 16 bit MS-DOS Subsystem
C:\WINDOWS\system32\cmd.exe - rh.exe
The NTVDM CPU has encountered an illegal instruction.
CS:xxxx IP:xxxx OP:xx xx xx xx xx Choose 'Close' to terminate the application.
Here is a picture of the issue (link to TwitPic): Error
If I go to the directory where the item was installed, I can run it and it works great. It's just something in the registration of the command to run from anywhere.
I did quite a bit of searching before asking and came up with nothing. It could be that I don't know what I should be searching for. So let me ask the question, is there a way to register an executable with gems for windows executable applications (built with .NET) and have them register properly with the command line? If so, how is that done?
UPDATE:
I found that gems creates a shim in the C:\Ruby\bin directory that points back to the other file. So there is a rh.exe file that is really just a text file. This is its contents:
#!C:/Ruby/bin/ruby.exe
#
# This file was generated by RubyGems.
#
# The application 'roundhouse' is installed as part of a gem, and
# this file is here to facilitate running it.
#
require 'rubygems'
version = ">= 0"
if ARGV.first =~ /^_(.*)_$/ and Gem::Version.correct? $1 then
version = $1
ARGV.shift
end
gem 'roundhouse', version
load Gem.bin_path('roundhouse', 'rh.exe', version)

if you're distributing it with the file "rh.exe"
then you'll want to create a file
bin/rh
s.executables << 'bin/rh'
then when it's installed gems will create an "rh.bat" file which runs ruby "bin/rh" essentially (as you've seen).
So within bin/rh put something like
result = system(File.dirname(__FILE__) + "/rh.exe" ARGV.join(' '))
exit 1 unless result

result = system(File.dirname(__FILE__) + "/rh.exe " + ARGV.join(' '))
exit 1 unless result
So the endresult should maybe look like? note the space after 'rh.exe'
