Disappearing Bitmap

[vinayak4gargya]

Hi.
A little trouble here, help needed.
Basically what happens in my program is that after a little time, the bitmaps from my program simply disappear!.. leaving behind a very blank and naked background with just the GDI figures left behind... (colours from the rectangles also disappear, probably deleting the brushes).
Why is this happening ?

I am guessing some sort of a memory glitch..

Any help will be appreciated.
Thank You

I guess it is because of some bug(s) in your program.

It would of help if you could tell me what might cause such behaviour...
Any experience with this problem?

Seriously, vinayak4gargya, there's about a million things that could be wrong. You'll need to provide a lot more information on what you're doing. My guess would be that you are painting somewhere outside of the WM_PAINT handler.

I m sorry my bad my bad!

Yes actually well i think the problem stems from the fact that i was using the same brush variable (hBrush) and initializing it again and again.

like i was doing this ::
################

hBrush = CreateSolidBrush(RGB(255,0,0));
SelectObject(hdc,hBrush);
.
.
.

hBrush = CreateSolidBrush(RGB(255,0,0));
SelectObject(hdc,hBrush);
.
.
.
hBrush = CreateSolidBrush(RGB(255,0,0));
SelectObject(hdc,hBrush);
...
################
and so on....
so this is wrong right?? i cannot initialize the same brush again and again?

Hi,

you can initialize it for 1000 times and more, but:

you have to Deselect it from the HDC and you have to delete it!

hBrush = CreateSolidBrush(RGB(255,0,0));
HBRUSH hOldBrush = SelectObject(hdc,hBrush);
// do something with that brush here ...
SelectObject(hdc,hOldBrush);
DeleteObject(hBrush);
