• Windows Forms Context Menu for a row in a DataGrid

  Any recommendations for implementing a context menu for a given row in a DataGrid Simple enough to do this for the DataGrid as a whole, but I don't see how to "bind" the contextmenu to the row that the user clicks on. For "extra credit", I'd like to augment the default contextmenu that you get when you right-click on selected-text with my custom menu items. Can anyone point me in the right direction Maybe you should listen to the CellClick event of the datagridview, check whether the cell click is RightButton click and inside your specieal row, if so, do specieal handling. ...Show All

• Windows Forms hosting controls / forms across app domains (alternatives or thoughts)

  I'm working on a designer type app where projects are created and visually edited. its an mdi type app where each "project" is loaded in its own app domain. each project is given a canvas and allows object to be dragged /dropped & configured on the canvas. right now I use a limited proxy to pass data values in and out of a property grid (the designed object sends a collection of properties & events to be designed, and those are hosted in a property grid). I'm in a bit of a design deadlock when it comes to extensibility. I want to provide an extensible properties editor dialog for the objects being designed / ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 2D animations

  I am going to implement 2D animation in my program. The animation use a list of bitmap (with alpha channel) stored in ONE binary file and therefore I create an array of texture before showing the animation. But I find that when I try to create all the textures at the beginning, the animation is okay, but loading textures is quite slow and the memory usage is also very large(1xx MB), which is not acceptable. Are there any method to reduce the memory usage Thank you A couple of points: 1) Are your textures sized in a power of two ie 512x512 pixels. Most graphics cards have an awful time with textures that ...Show All

• Visual C++ VC2005 Beta2 Crashes

  Hello, I'm running beta 2 on a W2k SP6 machine. I have a large solution converted from VS2003 that is all native C++ code. The development environment is having persistent crashes. A crash happens every minute or so and I get a group of dialog boxes that say something to the effect "unknown software exception 0xc000000d at location 0x7c3b3984, ok to terminate, cancel to debug"). I can choose 'ok' and continue running the program(!). I usually end up moving the message dialog mostly off screen and continue working (modeless dialog). Is this a known issue Another problem - when I change a project's properties (say disable warning 4996) and ...Show All

• Smart Device Development Serial port support

  I am trying to attach the serial port 1 of the emulator to the GPS receiver connected to my desktop. I can either use USB or Bluetooth GPS receivers, and they work fine on the desktop. However I can't seem to get it to work on the emulator USB: setup works (can select port) but no data is transmitted Bluetooth: COMport cannot be opened, setup fails. Are you saying that only plain old serial GPS receivers connected to COM1 on the desktop are supported Didn't they stop producing serial GPS receivers a decade ago FWIW, you may also want to check this thread: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1134808&SiteID= ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Won't draw primitives

Because of this you have to use the SetStreamSource method that set the stride, too. In your case the stride is equal to the size of one vertex. Dim Stride As Integer = CustomVertex.TransformedColored.StrideSize device.SetStreamSource(0, vb, 0, Stride) ...Show All

• Smart Device Development Privilege Certificates

  There is some confusion over the need for privileged signing in our product. We are porting to WMv5 PPC. According to the link, http://msdn.microsoft.com/library/default.asp url=/library/en-us/mobilesdk5/html/wce51conWindowsMobileDeviceSecurityModel.asp , this has one-tier security. Part of our product installs a small device driver that implements the stream interface. In order to get it running on one manufacturer's device, I had to sign it with the SDK privilege certificate and install the SDK certificates. It didn't work when signed with the SDK Unprivileged certificate. If this is a one-tier system, why didn't it wor ...Show All
