Posts: 7 		We were using RC Wintrans X8 Global in our project involving multiple .rwt projects. But after upgrading to RC-Wintrans 9 the Exit( ) function is not working and we are getting the following error after completion of the 1st .rwt project.
WinTrans - Object reference not set to an instance of an object.
The project file is closed as seen in the Wintrans Editor. But the Wintrans application is not exiting

Is it (1) your application which gets this message returned?
Or (2) is it an output in the RC-WinTrans Output window?

If (2) then it comes from the RC-WinTrans VBA system (a VBA macro) and can be ignored (usually). I don't think this is the reason for the Non-Exit.
The reason will be a (RC-WinTrans) COM object which has not been released.

Possible reasons:
1. you have requested an object from RC-WinTrans and it has not been release before unsing Exit().
Release the object first.

2. a "for .. each ..." loop (.NET) causes this problem. It produces the same problem as (1).
The loop must be realized/coded in a different way. I can help how to do.

Find out which code executed prevents RC-WinTrans to exit. Skip code until RC-WinTrans closes with Exit().

I checked once again the Exit() works for V9. I used a .NET C# as well as a C++ sample application.

public void CloseWinTrans()
{
if (m_rwtApplication != null)
{

// Determine Temp directory used by WinTrans. This is needed to cleanup
// residual files left by WinTrans after it exits.
string tempDirectory = m_rwtApplication.Tools.DirectoryTool.GetTempDirectory();
try
{
// Exit WinTrans
m_rwtApplication.Exit();
}
catch
{
// Ignore all exceptions on exit.
}

m_rwtApplication = null;

// Delete WinTrans residual files in temp directory.
if (tempDirectory != null)
{
string[] tempFileList = Directory.GetFiles(tempDirectory, "RWTTmpFile_*.resx");
foreach (string filename in tempFileList)
{
File.SetAttributes(filename, FileAttributes.Normal);
File.Delete(filename);
}
}
}
}

The error in Event Viewer is
Application: CreateResourcesAllLanguages.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.NullReferenceException
Stack:
at CreateResourcesAllLanguages.WinTrans.CloseWinTrans()
at CreateResourcesAllLanguages.Program.ExecuteWintransOnDir(System.String)
at CreateResourcesAllLanguages.Program.CallWintransOnDir(System.String)
at CreateResourcesAllLanguages.Program.CallWintransOnDir(System.String)
at CreateResourcesAllLanguages.Program.CallWintransOnDir(System.String)
at CreateResourcesAllLanguages.Program.Main(System.String[])

The same code works fine with RCWintrans 8 but giving up after translating 1st RWT project in case of RCWintrans 9. So I am wondering if anything changed as part of RCWintrans 9

Posts: 238 		It can be reproduced using your code.

There is an unhandled exception when you delete the file in the temp dir:
File.Delete(filename);
 "An unhandled exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll"

Remove this code and it works.

Note: RC-WinTrans removes all temporary files in this folder on exit.
You do not need to clear the temp RC-WinTrans directory. It is done by RC-WinTrans.

Posts: 7 		Sure I will try your solution. But I am just curious as to why it was working fine with RCWintrans 8 and causing error only in case RC Wintran 9.3 ?
