Hi ShaileshShinde,

Try catching the error. Like this....

        Catch Win32ex As System.ComponentModel.Win32Exception
        End Try

Hello Expert,

By adding above lines of code it shows an message as ...

The filename, directory name, or volume label syntax is incorrect..

Can you please help where the changes required..

mhm... try it this way:

startinfo.FileName = "C:\WINDOWS\hh.exe"
startinfo.Arguments = "-decompile " + sDir + "   " + filename

I think your problem may be that you mixed up filename and arguments!

Hope this helps!

Best regards

Hello Expert,

This works now!!! Thanks a lot!!!

One more query related to this..

If i de-compile more than 5 chm's files... the process atr background is still running..where as i got the msg as decompilation done....

what was the cause of this...or any other way of doing this..

Mhm i would guess that (becouse of Process is working assynchrone) that you're simply starting processes faster than they can worked! Do the background processes close after a while?

best regards
