User32.InvalidateRect Prototype

[KeithO]

As you may have seen in an earlier thread I am attempting to clear the "Setup Status" label on the STATUSEX dialog. Trawling the formum I have found a method using FindWindow and SetDialogText.

The problem I have is that the dialog is not repainting itself. I wish to force and InvalidateRect on the dialog but not knowing a great deal about prototypes, I can't seem to find the InstallShield data types to use.

If someone can tell me what they would be for this siganture that would be great.

BOOL InvalidateRect(
HWND hWnd, // handle to window
CONST RECT* lpRect, // rectangle coordinates BOOL bErase // erase state
);

😞 Surely there is someone who can tell me how to represent: CONST RECT* in an InstallScript prototype declaration!!

Please see the InstallShield help topic "Data Structures", which gives a similar example.
