Basically, visual inheritance is not supported in the compact framework if
thats what you are using. Here's the original link: http://groups.google.com/groups?threadm=eM0Ol8KECHA.824%40tkmsftngp05 If that doesn't resolve for you either, then goto groups.google.com and type in "visual inheritance cf" and look at the thread that has 18 articles and is dated June 10th, 2002. In one of the messages, someone mentions a work around for this. hope that helps... Imran.

I have the above problem with an inherited form, which was working
previously. I have a base form, frmBase which is inherited by my user forms. When I try to 'design' either frmBase or a user form, I get either the 'Specified Cast Is Not Valid' error, or the 'Ambiguous Match' error. Both of these are driving me crazy, as it was working previously. I have created a sample demonstrating this: http://www.j.goodman.dsl.pipex.com/Files/InheritanceExample.zip I am wondering if it is the setup on my laptop causing the problem (WinXP Pro, SP2 with .NET Framework 1.1 SP1). These are the only things I can begin to guess might be causing a problem, but I dont know where or how. Can you replicate this error with my sample? Any further suggestions? -- Cheers, James Goodman
Cannot get the link to work.
Can you post its content here? -- Cheers, James Goodman [quoted text, click to view] "Imran Koradia" <nospam@microsoft.com> wrote in message news:u1n9hiznEHA.3756@TK2MSFTNGP11.phx.gbl... > Are you using the CompactFramework? > Does this apply to you? > http://tinyurl.com/6bklz > > Imran. > > "James" <jamesATnorton-associates.co.ukREMOVE> wrote in message > news:unrODYznEHA.3876@TK2MSFTNGP15.phx.gbl... >> I have the above problem with an inherited form, which was working >> previously. >> >> I have a base form, frmBase which is inherited by my user forms.

Thanks for that.
Makes interesting reading, but I dont understand how it was working perfectly on my CF application a few weeks ago, & isnt anymore. It is VS.NET 2003, not the 2002 version. Not sure if visual design is supported in 2003? -- Cheers, James Goodman [quoted text, click to view] "Imran Koradia" <nospam@microsoft.com> wrote in message news:Os4KhZ0nEHA.2840@TK2MSFTNGP10.phx.gbl... > Basically, visual inheritance is not supported in the compact framework if > thats what you are using.
