Trouble Using the ShellExecute API Code

[RobPotts]

Hi

I found a link to the following code, which I believe will open a file in its associated application, I may be completely off the mark here, and please tell me if I am. But what i want to do is on the press of a button on a form the File whoes location is in a field on the form "TxtLocODoc" and open that file. These may be in different applications. Can somebody please help with the on click code. I'll continue playing about as well and if I have any joy I'll get back to you.
