• Visual C++ Automatically setting focus to edit box in a dialog box

  I have a modeless dialog box that has an edit box and a button on it. A command is typed into the dialog box and then the user clicks the button (or just hits the enter key) to dispatch the command. The program has several other windows running, but when the program starts, and after each command, the focus is properly set back to the dialog box. The problem is, you must still click with your mouse inside the edit box to get the cursor there and be able to type the command. Is there a way to make it so that when the focus goes to my dialog box, the text box is already active so that I can just start typing without having to use my mouse to click in the text box In case it is relevant, I am working in VC++ 6.0. ...Show All

  Hi guys, I'm using sql 2000 now but eventually will upgrade existing server to sql 2005. currently we only have OLTP dbs.

• Windows Forms Error Handling - Application level

  I know that .NET provides a default run-time error dialog that let's you review an error and then either continue or quit an application. Is it possible to replace this dialog with my own error handling routine I would like to write just one routine that will handle all errors at the application level. I tried to wrap Application .Run( new Form1 ()); in the Try Catch block, and it does work with the exception that I cannot do the Continue action similar to how .NET does it in its error-handling dialog. How can I write code to continue processing Thank you very much for your help! Evgueni The problem is, you don't necessarily want the user to be able to choose to continue.
