Hi,
I have a list of files with their paths in a data window and I would like to add functionality where the user could click the file and it will open using it's default Windows associated application.

Basically I would like to emulate the same process that happens when you go to windows explorer and just double-click a file, if it a word doc it launches word, if an excel doc it launches excel, etc. Windows opens it with it's associated application. I have the file name and path to pass to the Windows API call I just need to figure out how to make that call.

IDE: Powerbuilder 12.5.2 (Classic)
OS: Windows 7 64 bit

Thanks!

In your appliation object declare a global external function:

FUNCTION long ShellExecuteW( ulong hWnd, string Operation, string lpFile, string  lpParameters, string lpDirectory, int nShowCmd ) LIBRARY "shell32.dll"

Open in new window


And when you want to open a file do this:

string ls_filename, ls_null
SetNull(ls_null)
ls_filename = '"C:\Full\Path\To\File.XYZ"'

ShellExecuteW( handle( THIS ), "open", ls_filename, ls_Null, ls_Null, 1)

Open in new window
