Wizard97: Watermark and Header Graphics are repeated

2004-01-08 17:14:00 +0000

I was adding a new wizard to the program that I’m currently working on, so I copied some code from a Wizard97 demo program that I wrote some time ago.

When it comes up, the header and watermark graphics are displayed repeated.

This is shown in the following pictures:

The problem? PSH_WIZARD97 is defined differently, according to which version of IE you claim to be targetting:

#if (_WIN32_IE >= 0x0400)
//----- New flags for wizard97 -----------
#if (_WIN32_IE < 0x0500)
#define PSH_WIZARD97            0x00002000
#define PSH_WIZARD97            0x01000000

Apparently, Microsoft changed the value of the PSH_WIZARD97 flag between IE4 and IE5. Depending on whether you’re running against IE4 or IE5, you should pass a different value.

The simple fix, assuming that you’re only supporting IE5 or newer is to add the following to your StdAfx.h file:

#ifndef _WIN32_IE
#define _WIN32_IE 0x0500	// Allow use of features specific to IE 5.0 or later.

That’s better.

Note that if you claim to only support IE5 or later, you should put runtime checks for this in your code as necessary.
