I am running into a problem here, and I have no code needed or that requires debugging. I am looking for more of an idea to solve this issue, so here it is. I have a *.exe that is a command prompt utility that generates images. What I am doing is using this utility for my asp.net website. In the background I do processing for each date in a asp.net calendar. If the image doesn't exist in the images directory for that date, Calendar_DayRender calls the backend to use the exe via Process. The image creation works great. As does the loading, if the image was already created in a previous session by any other user. The problem is that the images are being created too quicky and I cannot load the image because when I try to add the Image to the cell, it was not created quickly enough. Any ideas on how I can solve this timing issue?
