    Hello everybody, im creating a picture control in a dialog box (win 32), i need to show an image in that control, but my bitmap is of 30 X 30 size, but the control is 100 X 100, i would like to stretch the image upto 80 X 80, so that picture control is filled with the same image. Thanks in advance, A. Gopinath.

      You may use my DLL [^], if you need to stretch it without loosing too much quality. :)

        I usually specify the required size in the LoadImage API in its cxDesired and cyDesired parameters.
