How i can save DC in Hbitmap...so i can use it Cimage...in SDI MFC
-
You cannot, a DC is effectively an output device that is created as and when you need to draw on it. Just save enough information about your shapes to redraw them on any DC.

Well the subject of your post says "How i can save DC in Hbitmap".

I'm not sure what you mean by this, can you make your question clearer?

Again your question is not clear. As I said earlier, you can save all the information about your shapes so that they may be recreated in some future application.

Could you please post your code? Isn't so clear what you have really done and what you're trying to accomplish. :)

Try reading the documentation[^]. Hint: look at the Save method.

Here is the code... //hbm & image are decleared in ChildView class but not initialized in any function...if i have to initialized them ,then how i can initialized them??
HBitmap hbm;CImage image;
//the following code is in OnPaint(); function
CDC *mdc = GetDC ();
HGDIOBJ tmp = mdc->SelectObject(hbm);
mdc->TextOutA (50, 50, Text("Testing"));
image.Attach (hbm);also tell me tht where i have to put image.Atach();function..i mean in OnPaint(); or in Save function?? :confused: //I'm drawing different shapes in OnPaint(); function using
CPaintDC dc(this);//Like dc.Rectangle(&rect);
& i want to attach it with CImage so i can save them... It is a SDI MFC non View/Doc arch. application...Plz tell me in Detail

I'm not sure of all the steps you need to follow to achieve what you are trying to do, but I would suggest you follow my previous advice and study the
CImageclass and its members to see what functions are available to create your bitmap and save it to a file. You could also search the articles here on CodeProject and Google for sample code. [edit]I just saw this article[^] which contains some useful tips.[/edit]It's time for a new signature.

What code? I have no idea what you are trying to do apart from saving something to do with GDI, for which incidentally, you have been given the answer in a previous thread.

The word is please! And you can do whatever it is you need by studying samples and the documentation that I pointed you to earlier (both cases).
