Access denied.

[krsh24]

Hi

I have to start a vc++ application from vb.net application. I have implemented it and the code snippet is

 With startInfo
                    .FileName = sPath
                    .Arguments = sCmdParams.Trim
                    .UseShellExecute = True
                    .RedirectStandardOutput = False
                    .WindowStyle = ProcessWindowStyle.Normal
 End With

 oProcess = System.Diagnostics.Process.Start(startInfo)

but when i call the start method some times i get "access is denied". can any one explain me under wat circumstances this error can occur.

Thanks in advance

If your application throws the Win32Exception with this message on this call to Process.Start it probably means user don't have permission for the file or folder. If it's the other application it could mean just about anything, but usually a permission issue of some sort.

Perhaps you need to set the WorkingDirectory to the folder containing the file.

Since WorkingDirectory here is empty and UseShellExecute is true, it means WorkingDirectory specifies where the executable is. In case current directory was changed and only relative path was specified for the executable I thought this would result in a "File not found"?
