The code problem A few days ago I had the chance to work on a case not concerning ASP.NET or IIS, but rather an interaction with Visual Studio designer with classes from System.CodeDom namespace. The customer was developing a custom control meant for other developers to use it in their projects, and upon adding the control to the form, the former had to automatically modify the some codebehind files for example to add some custom methods and register itself in the InitializeComponent method to add events etc… The problem was that we were able to add new methods to the form, but despite our attempts nothing was added to InitializeComponent ? Here’s the chunk of code we were using: private void AddCode(Form form) { IDesignerHost host = null; host = (IDesignerHost)form.Site.GetService(typeof(IDesignerHost)); //Add method "Form1_Load" on Form1 //--------------------------------------------------------------------------- CodeMemberMethod member = new CodeMemberMethod(); member.Name = "Form1_Load"; member.Parameters.Add(new CodeParameterDeclarationExpression("System.Object", "sender")); member.Parameters.Add(new CodeParameterDeclarationExpression("System.EventArgs", "e")); CodeSnippetExpression sn; sn = new CodeSnippetExpression("MessageBox.Show(\"Hello world\")"); member.Statements.Add(sn); member.Attributes = MemberAttributes.Private; CodeTypeDeclaration typedecl = (CodeTypeDeclaration)form.Site.GetService(typeof(CodeTypeDeclaration)); typedecl.Members.Add(member); //--------------------------------------------------------------------------- //This code will add the following line to the "InitializeMethod" method // this.Load += new System.EventHandler(this.Form1_Load); //--------------------------------------------------------------------------- member = new CodeMemberMethod(); foreach (CodeTypeMember typememb in typedecl.Members) { if (typememb.Name == "InitializeComponent") {…
