How are you drawing the image and which control are you using?
The StretchBlt function can stretch an image.

You can only display text in a text control.
For an image, you will need a picture control.

Why don't you simply place a text box in the middle and a picture control at the top of the dialog?

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?

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