SetLayeredWindowAttributes

[MrVB50au]

As Win98 doesn't support most dll calls like Win2000 and WinXP, the declaration below can't be found.

Is there away around this?

Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hWnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long

Thanks,

Andrew G.

You did not mention what do you want.
Do you need the documentation about this function?

It is available at:

http://msdn.microsoft.com/library/d...indowFunctions/SetLayeredWindowAttributes.asp

Two constants are used in the dwFlags parameter of this function. They are:

Const LWA_COLORKEY = &H1&
Const LWA_ALPHA = &H2&

But Win98 DOES support all dll calls if the function called actually exists. The function you're talking about only exists in Win 2000/XP.

The only way around it would be to capture bitmaps of the form and whatever windows are below the form, do a manual blend of the bitmaps and then draw the resulting bitmap to the form. Not very useful though.
