VBA Shell Function / Windows API Createprocess()

[BasildonBond]

I am trying to use the Windows API CreateProcess() to start a program within
a VBA application.

I have hit problems. Now going back to basics and trying to launch program,
with parameters, from the VBA shell function.

The appication starts sucessfully without the parameters ie

Retval = Shell("C:\Program Files\FastCut\FastCut",6)

Including parameters

Retval = Shell("C:\Program Files\FastCut\FastCut 12345.txt,1,5",6)

still launches the program but display errors.

I get the same problems when trying the same thing via a createprocess()
function.

Using the ShellExecute function within the 'Shell32.dll' library ......

strPathString = "12345" & ".txt" & ",1,5"

RetVal = ShellExecute(0, "open", "C:\Program Files\FastCUT\fastcut.exe",
strPathString, "C:\Program Files\FastCUT", 3)

....... everything works fine.

Running .......

C:\Program Files\FastCut\FastCut 12345.txt,1,5

.......from the command prompt causes no errors to be displayed and the
program runs as it should.

Can anyone help.
