View 1 RepliesAdd 2 user controls and display them on your default aspx page. One control will be a simple list of store contact information. The other control will be a featured product control which displays a featured product of your choosing with an image and a description.
So i created a web user control page something like stewiecontrols.ascx
And I want to how to register the page <@control ...... src="" prefix name="" prefix tag="" /> the rest of the code in html <div> ..... </div> tags.
My question is this. I'm creating a master page and the default page is created using master page. So how do I register this .ascx page on default page. Should I register the .ascx page under master page or how. I want the user controls to only be shown on default.aspx page.

View 2 RepliesI have a routine to display an image on an aspx page. The url for the image uses imagerender.aspx . This is simply an empty page with code behind:
myClass mysub = new Myclass(); // create class
Stream strm = mysub.DisplayImage(UserID); // call method to load bytes from db
byte[] buffer = new byte[2048];
int byteSeq = strm.Read(buffer, 0, 2048);
while (byteSeq > 0)
{
Context.Response.OutputStream.Write(buffer, 0, byteSeq);
byteSeq = strm.Read(buffer, 0, 2048);
}
Ok, this work fine when testing on my local machine, but when I move it to the live server, it comes up with an empty image box!
It looks like there must be a problem with security, maybe with ISS.
Does anyone know what changes I can make to fix this problem or what setting to change in IIS 7?
