• Visual Studio Express Editions stand by exe

  how do i make a simple exe that when i run it, ti puts windows in to stand by and what would be the same for restart, shut down, and log off Hi, look at SetSuspendState and ExitWindowsEx. To use them from vb.net you will need these declares. Declare Function ExitWindowsEx Lib "user32" (ByVal dwOptions As Int32, ByVal dwReserved As Int32) As Int32 Declare Function SetSuspendState Lib "powrprof.dll" (ByVal Hibernate As Boolean, ByVal ForceCritical As Boolean, ByVal DisableWakeEvent As Boolean) As Int32 -- SvenC ...Show All

• Windows Forms ClickOnce file share icon?

  This is probably a really basic (maybe stupid) question, but I have done several searches and haven't found an answer Here's one version of the documentation I'm referring to: Install from the Web or a Network Share Using this strategy, your application is deployed to a Web server or a network file share. When an end user wants to install the application, he or she clicks an icon on a Web page or double-clicks an icon on the file share. The application is then downloaded, installed, and started on the end user's computer. Items are added to the Start menu and the Add/Remove Programs group in the Control Panel . Where is the icon they are referring to in the statement: double-clicks an icon on the file share When I pub ...Show All

• .NET Development .NET 1.1 vs .NET 2.0 behaviour with Image fields

  In not .NET 1.1 and 2.0 the System.Type mapping for a SqlDbType of Image is byte[]. If you use this type to create a SqlParameter (with a value of DBNull.Value) and then use this in a SQL statement of the form "Update table Set ImageField = @parm where ......" Then in .NET 1.1 it works, but in 2.0 you get an Exception "nvarchar is incompatible with image" How can you determine the correct System.Type to use for Image fields, and why is the behaviour now different The application code is generic and not tied to specific database designs. Thanks Tony im not entirely sure about that one to be honest. I'm actually a bit confused on what you are trying to do - ...Show All

• .NET Development How to unregister a COM wrapped .NET assembly?

  Hi All, I created a COM exposed .NET 2.0 dll and registered with my Windows 2000 operating system using 'regasm' and 'gacutil' Then I tried to call this component from my classic ASP page. It worked fine. But, I need to change the functionality of my assembly. I unregistered it again using  'regasm' and 'gacutil'  utilities and copied my new .NET DLL and registered again.  But for some reason, i still have a pointer to my old assembly and new calls to the DLL from ASP page are not working. Any Ideas   I appreciate any help. Thanks     A common issue is that people don't explicitly assemblyversion. Then what happens is that every build produces a differ ...Show All

• Visual Basic Button_Click Events

  How does one going about Knowing when a event has happened from another method ie button_click event... basicly im trying to create a login form that will go to the main form if the values from user and pass are correct.

• Visual Studio 2008 (Pre-release) Making a custom menu like Vista's Photo Gallery

  I like the way that Photo Gallery, Media Player and Movie Maker have a black bar at the top with drop down buttons, and I have managed to emulate the bar itself, but not the buttons... I am hoping someone here can tell me how this is meant to be done Do I just create a rectangle and make it act like a button - OR - is there a preset way to do this I've almost completed it. I have the bar (looks identicle) and the button style is pretty-much finished. I just need to set the button as a resource... not as easy as I thought it was. Email me sometime and I'll give you the code. (my nick + @ hotmail . com) ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Question: How do I access the GraphicsDevice from inside a Component?

    I watched the Components Demo, and I wanted to write my own Grid component, until I bumped into a problem... How do I access the GraphicsDevice from inside the component I can't find anything in the documentation, and I can't draw anything. I could use a property or something like that, but from what I've seen in the video, this access is done internally ( i.e. I couldn't figure out how the components in the demo do this). Is there an official way to do this   Zima Catalin You can do this using the IGraphicsDeviceService interface: IGraphicsDeviceService service = (IGraphicsDeviceService)Game.GameComponents.GetService(typeof(IGraphicsDeviceService)); GraphicsDevice device ...Show All
