Use LoadImage to load the image.
Here you can specify the width and height needed.

Associate a CStatic object to the picture control.
Now use CStatic::SetBitmap to show the bitmap.

What if you "printed" the text on the image so that they are rendered together (as one)?

The text control has a property called Transparent.
Set this to True.

I guess you need to select that particular font into the device context.

Since you are saving the data, why can you not restore it? Or did I misunderstand your question?

Use SetWindowText().

Which means storing the data in the registry (if the amount of data is small), or a file.

How do you confirm that the given window handle is that of the main window, or the parent window ? If it is sure that the handle is of the main window, just call the SetWindowText API with the given window handle to change the window title.

Make sure that you are having the right window handle using the SPY[^] tool which you can find along with your Visual Studio installation.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
