system cannot find the file specified Exception

Question

Hi folks,

I am having problem with executing a program that uses a cmd command to run through the Visual Basic .Net. The code is as following

Dim myThemeProcess As New Process
Dim myTheme As New ProcessStartInfo

myTheme.FileName = "%SystemRoot%\system32\rundll32.exe %SystemRoot%\system32\shell32.dll,Control_RunDLL %SystemRoot%\system32\desk.cpl desk,@Themes /Action:OpenTheme /file:""" + filePath + """"

'myTheme.RedirectStandardInput = True
'myTheme.RedirectStandardOutput = True
'myTheme.UseShellExecute = False
myThemeProcess.StartInfo = myTheme
myThemeProcess.Start()

The exception comes at the last line. Can anyone help me?
