    Picture size check script?!

    I thought with the new oppertunities with ASP.NET (e.g. compiled DLLs etc.) I thought it would be possible to create a library that checks the width and height of a picture?
    I am using this to limit the size of pictures posted on my forum.

    I know PHP has built-in features for this purpose, but ASP.NET ...?!

    With the "PostedFile" object you may be able to check attributes of the file. If there is a way to do it in php it may be along similar lines but I'm guessing.
    There was an upload script for asp that limited image dimensions but it checked on the client presumably using javascript. You might want to search for a javascript that will do this.

    Never mind, I figured it out - got help on an ASP.NET forum...

    Only two lines of code needed :-) And no, it's not the postedfile object

    I suspected it might be that. I did not suggest the drawing namspace to you because I assumed you did not wish to allow the upload for pictures of certain dimensions.
    The code example will work fine but bear in mind you have to allow the upload and save it to your server before you can check it and presumably then delete it if it is not the correct dimensions.
