Error 998 in VB6 on Vista Home Premium
 |
I am trying to call the GetLayeredWindowAttributes(hwnd, crKey, bAlpha, dwFlags) function but it does not work.
I use Visual Basic 6 on Windows Vista Home Premium.
I declared it using:
I called it using:
Debug.Print shows that GetLastError() returns 998, which the MSDN says is ERROR_NOACCESS (Invalid access to memory location.)
byteAlpha is still the same value as before (1).
I can call the GetLayeredWindowAttributes in Dev-C++ on the same computer and it works fine.
Does anyone have any idea on how to call it from VB6 in Vista?

I was experimenting and found out the solution. You need to declare it without ByVal like this (except for hwnd as that is not a returned value):
This works now.
Visual Basic 4 / 5 / 6 Syntax (Toggle Plain Text)
This works now.

HI,
if that solution not works try this one
goto control panel-->user accounts-->User Access control
disable the UAC(Unchek the checkbox)
it will prompt for restart,
restart and try your code,
With regards
