• Visual C# Odd results after Console.read() input

  In the following little "learning" program of mine, I am making a simple class constructor program. The place I am having problems is with Console.Read(). If you run this program and go into debug, and once you come upon the conosle.read() the variable selection takes on some funky results. Selection is first initialized at 0, but as soon as you input for selection the number jumps way up. When I type in 1 at the menu, the variable takes on 49, 2 takes on 50, and 3 takes on 51. Obviously I am very new to this, and i'm guessing I am doing something wrong with Console.Read() but I don't know. class Menu { public void MenuOptions() { int selection = 0; while (selection != 3) { Console.WriteLine( ...Show All

• SQL Server SQL Management Studio from desktop PC connecting but no acccess to service functions

  I have a new and virtually full installation of SQL 2005 Developer with SP1 installed (named instance), on a Windows 2003 standard server, which also has a default instance of SQL 2000 SP4 installed. I have the browser service running also enabled TCP/IP for remote connections via configuration manager. All services are currently using LocalSystem.

There are no firewall issues here, just a hub separating the server from desktop. What am I missing ...Show All

• Windows Forms User interface question

  Hi all, I'm building a software which has a UI similar as outlook 2003. The problem I'm facing is how can I perform dynamic content change while the user click the navigation buttons. I did think about using MDI but that is not what I want as it obviously not how the outlook implement. Thus, i think about using panels and swap between them. However, it seems very hard to design as i need to cover a new panel to the previous one. It anyone can tell me how outlook implement the dynamic content change thxs alot. Create a custom usercontrol for each view. This way you can just toggle their visibility depending on the button that was click. Usercontrol creation is the key to creating a UI ...Show All

• Visual C# Blocking Console closure?

  I have a Windows Forms app with Console playing a part. I now run an almost debugged code from an exec that is generated after the Build command. I need to prevent Console from accidentally being closed by clicking on the tiny button located at the right upper corner. I cannot figure out if it is possible to do. The corresponding button on the form is blocked but it does not prevent the form from being closed by clicking on the button on the Console. I want to immobilize it too. I do not the app being closed accidentally in any event. Thanks. Figo Fei - MSFT wrote: What i meant is if you want to hide the close button of the form you'd set the form's controlbox.
