I recieve the following set of errors in the designer tab when I try and compile my program. I am new at using Windows Forms. I know you are not supposed to write code in the automatically generated code, but I don't know where else to put it. Could this be the problem?C++ CodeDOM parser error: Internal Error
at Microsoft.VisualC.CppCodeParser.OnMethodPopulateStatements(Object sender, EventArgs e)
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)
you are not supposed to put code in the automatically generated part, like in the initialize component method.
suppose, you put the following code in initialize component
this->Text = count;
you get an error window on the desinger similar to this though the error description might be different
if you put the following code
this->Text = "Text1";
the code is valid and you see the form caption change to "Text1".
Now suppose you add a button to the form by dragging from the toolbox, all the changes you made to the code are gone (like the statement above this->Text = "Text1").
You shouldn't be declaring variables in InitializeComponent; that's the whole point. You shouldn't be writing ANY code in InitializeComponent. If you are referencing class level variables, even if they are declared in the designer file, they are still accessible in the constructor.

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...
