>Yes I have VFp, but I do not want to build in a image viewer OCX Form if possible. As we have many here who have there own religious choice of image viewers (myriad, wang, kodak, ImageR, etc..) What I wanted is a way of detecting that the imager is up and just telling it to open the drawing and not open another copy of the image viewer with the drawing. We wanted to give our app some flexibility on image viewer, but this is a by product of the choice we made.
Oh, I understand you, but this will be hard, I think not all the Image viewers are DDE enabled, and have different ways of opening the images. For knowing if it's up George's Tasker ISRUN32, will do.
