C++ CodeDOM parser error: Internal Error

	One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.
C++ CodeDOM parser error: Internal Error Hide
at Microsoft.VisualC.CppCodeParser.OnMethodPopulateStatements(Object sender, EventArgs e) at System.CodeDom.CodeMemberMethod.get_Statements() at System.ComponentModel.Design.Serialization.TypeCodeDomSerializer.Deserialize(IDesignerSerializationManager manager, CodeTypeDeclaration declaration) at System.ComponentModel.Design.Serialization.CodeDomDesignerLoader.PerformLoad(IDesignerSerializationManager manager) at Microsoft.VisualStudio.Design.Serialization.CodeDom.VSCodeDomDesignerLoader.PerformLoad(IDesignerSerializationManager serializationManager) at System.ComponentModel.Design.Serialization.BasicDesignerLoader.BeginLoad(IDesignerLoaderHost host) Thats the error I get form the designer. Anyone have a clue what I have to do to remedy the situation? The code compiles and runs, the designer just won't show it. I'm using managed C++ in Visual Studio 2005 with /clrure

I have been having this problem as well, and in my search for a solution I found several threads like this where noone posed a solution. However, I potentially have one for you!!!

I have found that when your code gets quite large the auto generated code gets really REALLY messy! It even puts duplicate lines in and inserts code in the wrong place causing errors!!!

If moving the code to where it is supposed to be doesn't fix it, then there is another thing that the auto generated code forgets and is VERY picky about. Look for lines that are missing the "this->" parts! For example, it will start auto generating lines like the following:

Button_MyButton = (gcnew System::Windows::Forms::Button());

However if you add the "this->" part like its supposed to do like the following:

this->Button_MyButton = (gcnew System::Windows::Forms::Button());

then it stops complaining!

When your code gets large and these errors start occuring, you have to be very careful with the auto generated code!

I hope this helps people out there and saves them some time...

Cheers,
Carl

Hi everybody,

For anyone who has the same issue. Here is a tip on how to solve it.

It is like Carl said, most probably because the auto-generated code has been corrupted.

Some people like to add additional code between the auto generated code. This is a no go. Move all additional non-auto generated code in the constructor. Or rewrite your program in such a way, that you can leave the auto-generated code intact. This should solve your problems.

Cheers,

Fre
