• Visual C# why cannot C# make access to methods of grandparent class?

  Is it a flaw on C# Or, by design class A{ virtual string foo(){return "A";} } class B:A{ override string foo(){return "B";} } class C:B{ override string foo(){return base . base .foo();}// impossible } class D:B{ override string foo(){return ((A)this) .foo();}//impossible } class E:B{ override string foo(){return this. A:: foo();}//impossible } There are some times when I want to call methods of grandparent class... The creator of C# did not give us the way. Personally I think it's by design. If you need to get to the grandparent method, you should consider whether you really want the encapsulat ...Show All

• SQL Server Suspect Mode (no icon in SQL 2005)

  In SQL 2005 when a database is in suspect mode there is no obvious way to tell (via SSMS). In SQL 2000 the word "suspect" was displayed (via Enterprise Manager) next to the database, and the respective database icon was grayed out. Why was this behavior changed for SQL 2005 From a disaster recovery standpoint, it is very important to see immediately if a database is in suspect mode. Hi, I've checked with the SSMS team and this look like a bug. Can you please submit feedback through the Microsoft Connect system ( http://connect.microsoft.com ) This way we can notify you when the issues is re ...Show All

• Windows Forms ToolStripContainer and MDI

  Is it possible to use ToolStripContainer in an MDI application It seems that the ContentPanel does not have the IsMdiContainer property and thus can not be parent of an MDI child. Any work-arounds When you add an MDI child form to your main form by setting the MdiParent property (childForm.MdiParent = MainForm), a lot more is actually going on under the hood. The MainForm creates a new child window of class MdiClient, and it is this window that actually manages the MDI children (the MdiClient window becomes their actual parent). To control where the MDI child windows appear, you have to control the placemen ...Show All

However I want to be able to define multiple models in a same projects and so I need to write template that will do the same generation for each model found in the project. What I have seen right now is that each template includes a processor directive that specify the model file to use for generation. Can I modify that to iterate on each model file Thanks Dunno if there is an easy solution. Here is a somewhat difficult one which involves coding: Start the template engine manually in code under a menu click like explained here by AnnieM. Alter the code a little bit ...Show All

• Visual Studio Team System File is exclusively checked out by another user

  Hi, how can I unlock files which are exclusively checked out by another user Thx, Petr If the team project is set up to disallow multiple checkout, you'll have to undo the other user's change. Otherwise, you'll have to unlock it. The first requires "UndoOther" permission on the file, while the latter requires "UnlockOther". In either case, you'll have to use the command line to unlock the file. The syntax for undoing another user's change is: tf undo $/Project/folder/file.txt /workspace:WorkspaceName;DOMAIN\username /s:servername The syntax for unlocking another user's lock is: tf lock /lock:none $/Project/folder/file.txt /wo ...Show All
