(About the author)

This code will change the background color of a resourced dialog opposed to a Win32 window. Thanks Wolf McCould for reminding me of the CreateBrushIndirect() function. _________________________________________________ UPDATE: I've tested this code with static controls, it works perfectly.

Well, no problem. I posted it long time ago and I see it helped some people. I'm no newb anymore and I do much more complicated stuff, but it is always good to remember how to do basic things. Also, you should use CreateSolidBrush(color);

I have looked for 4 hours how to do this. I have been through many tutorials and google groups. Thanks so much. It worked like a charm. All I could find was mfc stuff. Thanks again. Shawn Nedwidek smn4780@cs.rit.edu

Not sure if the last message went through but I just wanted to thank you. I have spent many hours looking how to do this but could only find mfc. You rock. Thanks again

I was in your shoes before. But after finding some kind of code (maybe C), I thought of how it was used in lpszBackground, and how you could use CreateBrushIndirect() to use a different color rather white, grey, black. I'm making a new submission on common controls, so get ready.

is C++ software like VB??

C++ is very different from Visual Basic. First, it does not feature any RAD(ical) tools, most of everything in C++ has to be defined in code. In C++, you use APIs much more than STD, the main Win32 framework.

For newbies... Rapid Application Developpement (RAD)... Advanced Programming Interfac (API)... I don't know and I don't care about what STD means =P correct me if I'm wrong.

Danny, you should use CreateSolidBrush, which is a faster way to create a brush, since it does not require a LOGBRUSH.

2/15/2004 3:39:46 PM:Danny J
If you want to use styles, LOGBRUSH is anyones answer.

2/15/2004 10:16:03 PM:Wolf McCloud
Yea, but if you don't, like you are showing on the example, CreateSolidBrush is. Both ways are great. Anyways, I never, or rarely, use dialogs.

You do no need a break; if you have return (int)hBrush;

2/18/2004 6:34:08 PM:
Yes you do need the break. The break keyword is what tells the program to leave the switch statement. Without it, after that one message is processed, the program will go back to switch statement and will try to process another case. Since you cannot have the same value case in the same switch statement, the program will go through the entire statement until it reaches the end. If the break keyword is implemented, though, the program will leave the switch statement and go on normally. It really doesn't make a difference, but if you're talking sufficient coding, you need the break.

If you need more help, look up 'switch statements' on MSDN for more information on this small technicallity.

Wolf, API means Application programming Interface.
