Visual Basic question!!!!!

Hello,

I want to make a kind of executable in visual basic that helps me link to other executables like Autorun.exe on a cd. i made one using the shell command but I got an error, cannot find AutoRunGUI.dll. That dll is there in the folder where Autorun.exe is situated. Whys is it looking at the folder where my compiled exe is situated? Can anyone please help me with this? Here's the code:

Dim Result
Result = Shell("Foldername\Autorun.exe", 1)
Shell (Result)

Will Shellexecute solve the problem and can anyone please guide me on Shellexecute because when I try, the error Sub or Function not defined comes. Shellexecute I didn't try for autorun because this error came for anothere exe.

Code: ShellExecute(hwndMain, _T( "open"), _T( "C:\Some.exe"), NULL, NULL, SW_SHOW);

Thank You
