>are you shure that "Thisform.Refresh" only updates the values in controlsources? I do believe it will also 'repaint' the images on your from. "ThisForm.Draw" will repaint your images, but will not update the controlsource. So if you 'draw' and still have unupdated controlsources you will still see the old pictures, I believe.

Now I found the differences: Refresh() updates properties differently depending on the baseclass. For instance the label control updates the caption, but not other properties. I had forms where a logging output was on a label, which was made visible at the beginning of the procedure. During running of the procedure the changing text was not visible, because the label got visible after the process was finalized. In that case you need to draw() Right after making the contol visible.

Other controls work differently, a shape would be redrawn with Refresh(), and I suppose an Image would redraw the picture.

That was the reason I now use Draw() for the visual properties and Refresh() for controlsources, because Refresh() handles controls differently.
