Hello everybody I'm workin' on a project in which i have to load an image in an image box every period of time so i'm using a timer to do that, this image comes from another PC using the MScomm. The problem is that if the image didn't comletely and correctly arrive the computer stuck, even if i put "on error resume next" at the top of the timer. So is there any way i can check if the image is valid before loading it in the image box. I appreciate your cooperation and thank you very much.
