• Visual Studio Express Editions Full row select in readlonly DatagridView and EnterKey

  Hi Am am using datagridview in readonly mode with fullrow select turned on. When I press enter bring up a dialog to handle the Adding/inserting of records. After the dialog is closed, the selected row moves to thenext record. how can I stop this default behaviour. I would like the selected row to stay the selected row. I have looked at other posts but the all involve calling ProcessRightKey to get the focus to the next cell. Unfortunaltly I am unable to tranlate that solution into my requirements. Hi, You mean to press enter and not let the datagridview to go forth to next row, right If so, you can override ProcessDialogKey and ProcessDataGridViewKey method in datagridview. To c ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. A tool to help with Sprite Animations: Sprite Strip Composer

  Hi: I have been working on a game written in the XNA Framework. The game has many sprite animations. After researching how other do this in the community I adopted the approach of loading a "Sprite Strip" (PNG) consisting of a row of frames. If there are many frames and the sprite is large, I split them up onto multiple rows. One of the laborious tasks was creating such 'Sprite Strips' from a sequence of PNGs. I have created a very basic Windows Application named Sprite Strip Composer to solve this time consuming problem. Download: Sprite Strip Composer Instructions: Browse to a folder containing your PNG files. Select the files you want included in the strip. Make sure the animation looks correct by looking at the Animated ...Show All

• Visual Studio 2008 (Pre-release) Window Management

  I have a StackPanel that is used to display one or more objects of type 'Gadget'. The Gadget class is derived from Border and INotifyPropertyChanged. It contains several different controls, one of which is a CheckBox that opens and closes a child Window to display the properties for the given Gadget. I've tried a few different methods to instantiate and manage this Property child Window, but they all have had different problems. I will outline the desired behavior and hopefully someone can help point in the best to to implement it. 1. The Property window should show/hide itself based on the state of the CheckBox in the parent Gadget. 2. The Property window should have a caption bar with the standard min/max/close buttons. When closed by ...Show All

• Community Chat Zune and the iPod

  I've been following the Zune announcements fairly closely here at work. If you follow my blog, you'll see that I'm pretty passionate about media technologies, and recently went through the pain of migrating away from iPod/iTunes and onto Yahoo Music/Gigabeat S (Portable Media Center). Here the blog category where I talk about it: http://blogs.msdn.com/joemorel/archive/category/13772.aspx Now Zune is in the mix. It looks pretty neat, but I'm not sure if people are really going to go for the whole WiFi thing. I'm just not sure that I want to listen to the same music as the person sitting next to me on the bus. What do you think I use a Bluetooth handsfree device in my car (not headphones) wired into the car radio. It's not st ...Show All

• .NET Development Beginner Questions

  1. When creating a new WCF project in VS2005, I have the choice of File | New | Web Site... | WCF Service and File | New | Project | WCF Service Library. What is the difference between the two and when would I select one over the other 2. When I select the "new web site" choice from above, I get a basic "hello world" project created for me by VS2005. I rebuild the web site w/o any errors but when I run it, it only displays the contents of the service.svc file (I ran ServiceModelReg -i, but had the same results). Why 3. Why didn't any DLL get created as part of the build process in step 2 I got an App_Code directory with a cs file but no DLL. 4.

• Visual C# reinterpret_cast in c#

  Hi I am converting a visual C++ application to C# and there is a code that i don't know what i should do with BitmapData img_buf = image.LockBits(rect, ImageLockMode.ReadWrite, PixelFormat.Format8bppIndexed); unsigned char* pData = reinterpret_cast<unsigned char *>(img_buf->Scan0.ToPointer()); Does C# have somethign equivalent to reinterpret_cast in C++ Thanks a lot for your help Best regard Duong For the most part reinterpret_cast is only there to satisfy the compiler when you are doing an inherently unsafe conversion and an analog in C# would depends on what the actual types are as it is ultimately up to the CLR to decide if the type conversion can and will occur. How much control do you have over the code that the p ...Show All
