CDC* pDC = this->GetDC();
dc.CreateCompatibleDC(pDC);
CBitmap* pOld = dc.SelectObject(&img);
for(int y = 0; y BitBlt(200, 200, bmp.bmWidth, bmp.bmHeight, &dc, 0, 0, SRCCOPY);

If you have a new question then start a new thread, that way everyone gets a good chance to see it and you are much more likely to get an answer. Plus you can format it properly so it is easier to read. Thank You.

Radio buttons need to be in a Group Box and need the Auto Style option set if they are to select/deselect automatically.

Here's a nice little article about radio buttons that should help:

It's not necessary for the radio buttons to be in a group box. It IS necessary that the first radio button have the WS_GROUP style, and for all the radio buttons to have the BS_AUTORADIOBUTTON style.

Solution 2

Check if tab order and grouping are correct.

Here's what you do (this is a three-year old memory, so you may have to tweak it).

0) Put a GroupBox control on your form.

1) Put the radio buttons inside the groupbox.

2) Set the tab order, starting with the radio buttons, and finishing with the groupnbox.

3) Set the first radio button to be a group and a tab stop

4) Set the groupbox to be a group

5) You're done.

If you have a problem, GOOGLE it.
