Null reference in client

Hi!
I am getting a null reference into a TargetInvocationException.

The form type was not found in Gizmox.WebGUI.Forms but in the gAgenda.Forms1 (gAgenda is the project namespace).

any ideas?

thx in advance.

Re: Null reference in client

Hi,

Did you change the start form name?

Check that the web config key which maps application entry points is correctly configured and is pointing the right

Form object:
    <Applications>
      <Application Code="MainForm" Type="Gizmox.WebGUI.Forms.Catalog.MainForm, Gizmox.WebGUI.Forms.Catalog"/>
    </Applications>

Type should contain the fully qualified name of the start form: "<full form name - including namespaces path>, <assembly name>" and in case it is strongly names you can add public token.

Regards,
Itzik Spitzen

Re: Null reference in client (getting similar error)

I followed the howto, in program.cs set the get as

wrapped the .Run in a try/catch, here is the exception

e.Message = "Exception has been thrown by the target of an invocation."

Using 6.0.1, vs 2008, .net 3.5

return typeof(Gizmox.WebGUI.Forms.Catalog.MainForm);

Re: Null reference in client (getting similar error)

Hi Bill,

Thanks for the code sample. We also got the "Exception has been thrown by the target of an invocation" when running with the CatalogSmartClient as the startup project. Then we checked the basic VWG project and found that we were getting an exception in some of the code that you added to the MainForm.cs file. Could you please try running the solution again making sure that the VWG project runs properly and let us know what happens.

Thanks,

Gail Steiger
