• Windows Forms MDI Client should manually register in menu without beeing instantiated

  I build an MDI Application. Each different kind of MDI Child should be able to selfregister in a global menu bevor a concret Instance is created. Is this possible, and how. The best form me would be a base class for all MDI Childs where this functionality is covered. I am looking forward for your help. Thanks. nobugz wrote: I'm guessing you're looking for a way to dynamically add MDI forms to a parent that doesn't know about them. It is difficult to query a class for a property without instantiating it. Even more difficult if you don't know the class name. Reflection could help out. You can add a constant to a class and retrieve its value. Something like this: public partial class Form2 : Form { ...Show All

• Visual Studio 2008 (Pre-release) Refactoring?

  Will you ever implement refactoring for Visual C++ QbProg Actually, I think the issue is not a lack of recongition of the need, but the inherent difficulty. At some point (post Orcas), the C++ compiler will have shiny new AST-based front-end (like the C#, VB, J#, etc. compilers already have). Having an AST-based front end greatly enhances the ability of the team to build tools like refactoring since they don't have to reproduce all of the subtleties of parsing C++ (it's literally an order of magnitude harder than parsing just about any other language). ...Show All

• Visual C# Component class, list of values to an attribute.

• .NET Development Using reflection to Build Dynamic Report Form

  I want to use reflection to build a dynamic report form using the Table Adapters created with the Data Sources Wizard. I need to be able to reference the current instances of a Table Adapter and DataTable knowing only the names of the Table Adapter and DataTable at runtime. The name of the objects will eventually be passed from a value stored in a database. I have figured out how to get a reference to the class for the Table Adapter, but not how to get a reference to the actual current instances of the Table Adapter or Data Table. The code I have so far is: Assembly a = System.Reflection. Assembly .GetExecutingAssembly(); foreach ( Type t in a.GetExportedTypes()) { string tableAdapter = "CasesTableAdapter" ...Show All
