ShellExecute WinAPI function

[Javier Español]

Hi!,

I want to use the WinAPI ShellExecute function from within a PB program but
don't know how.
This function receives as a parameter (and some other parameters) the path
and name of a file and makes Windows execute the file in the application
that is registered to open that file type.
For example, if you pass C:\windows\myLetter.doc, the function will attempt
to open that file in WinWord.

TIA,

Javier Español

Here's a code sample:

// external function declaration
FUNCTION long ShellExecuteA( ulong hWnd, string Operation, string lpFile,
string lpParameters, string lpDirectory, int nShowCmd ) LIBRARY
"shell32.dll"

// PowerScript
Long ll_rc
String ls_null

SetNull( ls_null )
ll_rc = ShellExecuteA ( Handle( w_frame ), &
"open", &
"c:\windows\myLetter.doc" + Char(0), &
ls_null, ls_null, SW_NORMAL )

IF ll_rc > 32 THEN // 0-32 are OS error codes
// Word should be opened now
ELSE
// handle error
END IF

Javier,

Have you tried the PowerBuilder Run() command? In your PowerScript, place
the following line:

Run("C:\windows\myLetter.doc")

This should start word and open myLetter.doc. If this doesn't work and you
still want to use ShellExecute, you need to declare an external function.
In the PowerBuilder Help, look up "external functions". This should give
you the info. you desire.
