See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to class type 'mshtml.HTMLFormElementClass'. COM components that enter the CLR and do not support IProvideClassInfo or that do not have any interop assembly registered will be wrapped in the __ComObject type. Instances of this type cannot be cast to any other class; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface. at Recruiter.Recruiter.EnterNumber(Int32 nr) in C:\Users\floris\Documents\Visual Studio 2005\Projects\Recruiter\Recruiter\Recruiter.cs:line 277 at Recruiter.RecruiterForm.textBox1_KeyPress(Object sender, KeyPressEventArgs e) in C:\Users\floris\Documents\Visual Studio 2005\Projects\Recruiter\Recruiter\RecruiterForm.cs:line 259 at System.Windows.Forms.Control.OnKeyPress(KeyPressEventArgs e) at System.Windows.Forms.Control.ProcessKeyEventArgs(Message& m) at System.Windows.Forms.Control.ProcessKeyMessage(Message& m) at System.Windows.Forms.Control.WmKeyChar(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.TextBoxBase.WndProc(Message& m) at System.Windows.Forms.TextBox.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) ************** Loaded Assemblies ************** mscorlib Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.42 (RTM.050727-4200) CodeBase: file:///C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/mscorlib.dll ---------------------------------------- Recruiter Assembly Version: 1.0.0.0 Win32 Version: 1.0.0.0 CodeBase: file:///C:/Documents%20and%20Settings/Administrator/Desktop/desr/Recruiter.exe ---------------------------------------- System.Windows.Forms Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.42 (RTM.050727-4200) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Windows.Forms/2.0.0.0__b77a5c561934e089/System.Windows.Forms.dll ---------------------------------------- System Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.42 (RTM.050727-4200) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System/2.0.0.0__b77a5c561934e089/System.dll ---------------------------------------- System.Drawing Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.42 (RTM.050727-4200) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Drawing/2.0.0.0__b03f5f7f11d50a3a/System.Drawing.dll ---------------------------------------- Microsoft.mshtml Assembly Version: 7.0.3300.0 Win32 Version: 7.0.3300.0 CodeBase: file:///C:/Documents%20and%20Settings/Administrator/Desktop/desr/Microsoft.mshtml.DLL ---------------------------------------- System.Configuration Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.42 (RTM.050727-4200) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Configuration/2.0.0.0__b03f5f7f11d50a3a/System.Configuration.dll ---------------------------------------- System.Xml Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.42 (RTM.050727-4200) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Xml/2.0.0.0__b77a5c561934e089/System.Xml.dll ---------------------------------------- ************** JIT Debugging ************** To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section.
