This is driving me crazy!

Why does the following code work OK when called with the debug statement in place and I step through the code; but fail (hTB is always zero) when called from within my code without the debug? I am running under Windows Vista.

Is Vista doing something?

Function [/color]TaskBarHeight([/color]Null[/color]) 
[/color] 
[/color]Declare Function [/color]FindWindow, Struct_To_Var, Blank_Struct 
[/color] 
[/color]debug 
[/color]hTB=FindWindow([/color]'Shell_TrayWnd'[/color], [/color]''[/color]); 
[/color]if [/color]hTB=[/color]0 [/color]then 
  [/color]Result=[/color]0 
[/color]End else 
 [/color]TBRect=Blank_Struct( [/color]"RECT" [/color]) 
 [/color]Call [/color]GetWindowRect(hTB, TBRect) 
 TaskBarRect=Struct_To_Var(TBRect, [/color]"RECT"[/color]) 
 Result=TaskBarRect4] [/color]- TaskBarRect2] 
[/color]End 
[/color] 
Return [/color]Result[/color][/color][/size]

Jim,

How is FindWindow prototyped in your copy of OI? In mine it appears to be this (from DLL_USER32)
 HANDLE STDCALL FindWindowA(LPCHAR,LPVOID) AS FINDWINDOW
Which means I would have to call it like so:
 hTB=FindWindow( 'Shell_TrayWnd' : \00\, 0 );

Thank you, that did the trick.

For anyone that is interested the following code returns the height of the Windows task bar.

Function [/color]TaskBarHeight([/color]Null[/color]) 
[/color]******************************************************** 
* returns height of Windows task bar                   * 
******************************************************** 
[/color]Declare Function [/color]FindWindow, Struct_To_Var, Blank_Struct 
[/color] 
hTB=FindWindow( [/color]'Shell_TrayWnd' [/color]: [/color]\00\[/color], [/color]0 [/color]); 
[/color]if [/color]hTB=[/color]0 [/color]then 
  [/color]Result=[/color]0 
[/color]End else 
 [/color]TBRect=Blank_Struct( [/color]"RECT" [/color]) 
 [/color]Call [/color]GetWindowRect(hTB, TBRect) 
 TaskBarRect=Struct_To_Var(TBRect, [/color]"RECT"[/color]) 
 Result=TaskBarRect4] [/color]- TaskBarRect2] 
[/color]End 
[/color] 
Return [/color]Result[/color][/color][/size]
