BUG: Frameset Page that Hosts Windows Forms Control that Uses Localized Assemblies Does Not Load the Control the First Time (814663)


The information in this article applies to:

  • Microsoft .NET Framework 1.1
  • Microsoft .NET Framework 1.0

SYMPTOMS

When you try to browse through a frameset page with frames that host Microsoft .NET Windows Forms (Winforms) Controls that use localized assemblies, Microsoft Internet Explorer may not respond the first time. The page may load correctly with successive tries to browse it.

WORKAROUND

There are two ways to work around this problem:
  1. Increase the maximum number of connections for each server.

    Note This technique increases the connection load on all HTTP servers that Microsoft Internet Explorer visits, and then globally forces Internet Explorer to violate the HTTP specification. This workaround is only recommended if Internet Explorer frequently does not respond, and if you cannot change the code for the Web site.

  2. You can initially host the frame in a non-frameset page. Mark the page as hidden, to make download of the control easier. Subsequently, when you locate the frameset page, the control in the frames loads correctly. You can initially browse the non-frameset page that hosts the control. When you browse the page, the control downloads to a local computer. Subsequently, when you locate the frameset page, the control in the frames loads correctly.

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
