Thanks SA for your question, I code "Console" platform. Hope you help me.

Sorry, "Console" is not a platform. And, with your problem, it does not matter at all if you use console or not. Do you mean Windows, Linux, something else?

If you're going to do it with the Windows API (really it's GDI component), You need to know about handling memory DC's. That's quit a long topic give you a full answer.

Here're some sources :

>> A Codeproject Article - http://www.codeproject.com/Articles/224754/Guide-to-Win32-Memory-DC
>> Search google - There's plenty of things about DCs

hi dear sergey
if you work with visual c++, below code helps you:

CImage i;
i.Load(_T("a.bmp"));
CDC cdc;
cdc.Attach(i.GetDC());
cdc.TextOut(_T("Hello world"),10,10);
cdc.Detach();
i.ReleaseDC();

Thanks, your code is used for MFC?

I wanted to advise you to find it out from the CodeProject article referenced below, but wasn't sure you are asking about Windows. Still not 100% sure, but I saw that you mentioned MFC and some of your other questions was for Windows. Please see:
Drawing lines, shapes, or text on bitmaps[^].

Please see my comments to your question, and, next time, please understand that the platform tag is almost always important for your question.
