I have a webpage(.aspx) where users can upload images.
This upload button also triggers a postback to the server so image type checking can be performed and the image uploaded.
My problem is once the server is done processing the image and returns the .aspx page to the user how can I close the "Please wait" window?
I have seen similar posts suggesting this method:
MyWin = window.open()
The opening bit works but then if I put the close bit in the page load handler of the .aspx page it doesn't work.
