• Visual Studio Express Editions New VB user questions

  I am an experienced programmer in QB but new to VB. I have VB 2005 Express and am trying to get up to speed. For a learning project, I have a simple Windows form that calculates a Cylinder volume. The form has labels and test boxes for input, a results box, and 3 buttons (Calculate, Next, and Exit). Functionally, all works correctly so far. Question 1 - How do I set up to use keyboard navigation for data entry going to the next field or button The TAB key will jump to the next field, but not trigger a mouse click. The Enter key does not do anything. Question 2 - How can I cause a jump to a desired field on a data entry error such a ...Show All

When I get to the MyDll. the Intellisense shows the Interfaces available. I've tried numerous unclear explanations about interoperability but I can't find a clear, straight forward explanation. I know .net has its advantages, but considering the massive changes vb.net brought, there really& ...Show All

• Visual C++ controlling user input

  I'm writing a game. A very symple game that doesn't use objects or anything like that. (I'm relatively new to prgramming and haven't gotten that far yet.) Over and over again the program asks the user for input. Some examples: cout << "Play (or try, failures) again, Yes(1) or No(0) " ; cin >> pg; cout << "Show attack score, Yes(1) or No(0) :" ; cin >> showatk; Since these questions only have two anwsers, the variables pg and showatk are of bool type. This all works fine, until the user tries to answer ...Show All

• Visual C++ Visual c++ .net licence agreement

  A couple of months ago I bought a Visual Studio .Net 2003 Academic Edition. Unfortunately the licence doesn't allow the software to be installed on more than one pc (I didn't know at the time). Last week I tried to install it on another pc, but - of course - it couldn't be activated. The reason I want to do this is that I live with my parents in the weekend, without access to my own pc.
