• Visual Studio Cannot debug a form method called from a thread

  hi folks, i'm trying to break and step through a method in the main Form of a c# program. it is called by a thread created by the same form. it breakpoints fine but the cursor is dead for something like 5 to 8 seconds. after that, if i attempt to view and local variable data, it says "evaluation timed out. you must continue execution" or something close. the real problem is that when i hit F10 to step, the calling thread behaves as if terminated (i have no code that specifically aborts it); poof it seems to be gone. i could'nt swear to it but with vs2005 beta2, i had no problems; i'm now using the RC. one other thing i should mention is that ...Show All

• Windows Forms Another newbie question

  Hi, I have a treeview control and when user select a supplier or order from treeview, application will display supplier or order details depending upon user selection. My question is that is it better to open a new form or use panels to display supplier or order info Thanks Well... better... that's more of a design issue.

Instead of using a panel with dedicated controls on the right panel, you may also want to ...Show All
