Timer issue Hi all i`m trying to figure out how to use a timer to do something for a couple of seconds. Let`s say i want to prompt a message for 5 sec and after to disappear it. Or On a button`s click to appear an image and after 3 sec to disappear it. How i`m i going to do it?

Re: Timer issue Drag and drop a Timer component from the toolbox onto your form and then you will see a timer icon below your form - click on it and then set its Interval property to however long you want the image to be shown for (3 seconds would be a value of 3000 as its in milliseconds). Now double click the timer under your ...

Application.Current.Shutdown EDIT: See post 5 for explanation of why I'm talking about Application.Exit here when the thread is titled Application.Current.Shutdown So does anyone ever actually use Application.Exit? I mean is it considered a bad practice to just make everything instantly stop? The reason I ask is because ...

Problem With Shortcut Keys
Published (2009-12-14 12:44:00)
Re: Problem With Shortcut Keys Basically that amounts to needing a system wide hotkey, because your app will not have focus when it is in the system tray, so you need to monitor the system globally for the keypress. Look up the registerhotkey API, there should be some examples on this forum. __________________ Using VB.NET 2008/.NET 2.0/3.5 * Please mark you thread resolved using the Thread Tools above PLEASE INDICATE WHAT VERSION OF VB YOU...

questions on rgb/argb
Published (2009-12-14 10:06:00)
Re: questions on rgb/argb 1) The two are seriously different. If you just compare 0,0,127 to 0,0,255, you will see that both are blue, but of much different shade. Changing the alpha level should just alter how much of the background color bleeds through whichever shade you are setting. With that error, you might as well leave off the A value. 2) The two are not EXACTLY equal. In fact, I would expect that you can see the difference, though it...

Re: Need help: Write programs like Media Center Can you be a little more specific? Which particular effects or parts of the UI are you talking about? In general, if you want to make a nice looking application in VB.NET, the best thing to use is WPF - we have a forum on here for that: http://www.vbforums.com/forumdisplay.php?f=86 Here's an example of a program made with WPF: and another: __________________ Would you use my SMTP server...

[RESOLVED] Calendar
Published (2009-12-14 10:07:00)
Re: Calendar To move to Today's date, set your selection start to Date.Today. The Calendar has an AddBoldedDate method, so logically the RemoveBoldedDate probably removes bolded dates. __________________ Negative 0 Blog | RegEx | Encrypting UN/PW in Web.Config | Enabling ASP.Net on IIS 6 | Port Numbers | Creating GUIDs | Start->Run | Modifying the default class

Class diagram for a game
Published (2009-12-13 05:27:00)
Re: Class diagram for a game A few things: - Why is number of players in Player? Would make more sense in Game. - A player has exactly one TileBank so you can make a connection there. - A TileBank has at most 7 or something (can't remember) Tiles, so you can make another connection there. - A Board has exactly 15*15 Squares (assuming you mean that by Square), and at most 15*15 Tiles. The Tile class should have something to identify it...
