  How do I display the method parameters in the diagram I can only see the return types. If you want a preview of this feature, you can download June CTP and try it out.  Of course, it comes with the usual caveats of a CTP.  See http://blogs.msdn.com/robcaron/archive/2005/06/15/429278.aspx for more details.

• Windows Forms DataGridView/DataSource performance

  I am setting the DataSource to a DataGridControl that I am filling (in the Form1_Load method) from a List-derived object. This was working fine, but with more than a few 100 entries in the list it is now taking a long time for the form to show - several minutes with 0x250 entries. Is there anything I can do to speed this up   I don't understand why a hyper-threaded P4-3000 should need so much time!  Once the control is displayed perf ...Show All

  Are there any functions in C# such that when I pass a string into the function, it returns the unicode of the string For example, if I pass the string "abc" into the function, it returns the string "616263" (or "610062006300").

• Visual Studio 2008 (Pre-release) Lambdas and type/variable checking

  I would like to use lambdas with a custom object model.  The lambda would be turned into a parse tree and I would execute that against my application object model, much like DLINQ or XLINQ are able to do so.  This requires that somehow the compiler know what are valid properties, operators, types, variables, etc in the expression.  How is this accomplished   Will this be available to the end-user of LINQ.  This would mak ...Show All

• Visual Studio 2008 (Pre-release) Usercontrol Nightmare

  I do not know what I am doing wrong but I am starting to pull my hair out. I am using VS and EID to create a quite complex UI, and I am trying to use usercontrols to encapsulate as much as I can. However... Any user control I create and put on a window or page either never renders and just shows up with the classname of the usercontrol in the top left corner, OR when you place it on the page in EID it says "Cannot instantiate <ClassN ...Show All
