Calling win32api functions from powerbuilder

    I used to use a function called FindWindow in the user.exe windows 3.11
api library. I want to move my app. to a 32 bit app. on windows 95 using
pb5.0. How do I declare this function in windows 95 and what library can i
find it in? The old declaration syntax was:

function int FindWindow (string classname, string window) library "user.exe"

Any help will be greatly appreciated.

FUNCTION uint FindWindowA (long classname,  &
string windowname) LIBRARY "user32.dll"

Then add code like the following to your application's open event:

uint  val

val = FindWindowA(0, "MyApp Main Window")

IF val > 0 THEN
 MessageBox("Application already running", &
 "MyApp is already running. You cannot &
 start it again")

Calling a Java function from PowerBuilder
Hi all, We need to call a Java function from within PowerBuilder. I realize PB 6.5 can generate Java code but how do we call the functions?

PowerBuilder 11 and .NET: Callback function that passes foreign types to PowerBuilder
