"The requested lookup key was not found in any active activation context" and Process.Start()

Posted by Peter Ritchie on Wednesday, October 05, 2005 (EST)

Work-around for "The requested lookup key was not found in any active activation context" exception when using Process.Start() to spawn a browser with a URL.

It's appears there is sometimes some threading issues when using Process.Start() to spawn a browser by starting a URL. It's not too clear what the issues are; but the following works around the problem (C#):

    Process process = new Process();
    process.StartInfo.FileName = "rundll32.exe";
    process.StartInfo.Arguments = "url.dll,FileProtocolHandler " + url;
    process.StartInfo.UseShellExecute = true;
    process.Start();

What's the context? Is this in an application you've written?

"The requested look-up key was not found in any active activation context" When trying to open a web-site from my toolbar - I receive this message. Can you tell me exactly how to fix this - not very computer literate.

Fixing

The only way to fix the problem is to change the software. If this isn't software you are writing, only software you're using (that someone else wrote), you'll have to contact the author/vendor to get them to fix it.

VB Conversion
By macAsp on Thursday, May 01, 2008 (EST)

Peter,

I have "inherited" a vb project which I'm trying to convert to VS 08.

When running the conversion process/wizard it returns with the error:

"The requested lookup key was not found in any active activation context."

As I am new to this version I would really appreciate any pointers you could give me.

R&T,

mac.

Error with VB conversion wizard
By Peter Ritchie on Thursday, May 01, 2008 (EST)

If this is an error when running the VB conversion wizard, I would suggest contacting customer support--that sounds like a defect.

Alternatively, you could try asking on one of the VB forums like Visual Basic Interop and Upgrade
