Hi

I am trying to create a Web applicatiion by using windows
user control. I am having problem when I trying to load
the web page, I got blank screen with a broken image. It
is like the web page trying to load an image but the file
is not in the Folder.

I have set the Execute Permissions to Scipts only in IIS.
I have also checked the index.html and Win_Ctrl_Lib.dll
are in the same folder. Then Namespace and the control
method is correct too.

Is anyone can help me?

Regards,
Chung
