• Visual Studio 2008 (Pre-release) Using controls defined in exe-assembly from external xaml-files.

  I have a program that can load xaml-pages and resourcedictionarys from an uncompiled xaml-file during runtime. This works fine but one thing that bothers me is that all controls i use in these files has to be compiled in a dll-library, if they are in the main exe it won't work. Take this resourcedictonary as example: <ResourceDictionary xmlns:MyNamespace="clr-namespace:MyControlLibrary;assembly=MyControlLibrary" xmlns=" http://schemas.microsoft.com/winfx/2006/xaml/presentation " xmlns:x=" http://schemas.microsoft.com/winfx/2006/xaml " > <Style x:Key="testbutton" TargetType="{x:Type MyNamespace:GUIButton}"> //Properties here </Style> </ResourceD ...Show All

• Visual Basic Layering JPG files in PictureBox

  Hi, I am having some difficulty with a project I am working on and I haven't been able to get much help on it. I want to create a stoplight using GDI+.

• .NET Development Timer not firing at set rate...

  I set up a timer for my basic form. The only problem is that it only fires at 30 times per second. I would like it to fire at 60 times per second so I set it's interval to 15 milliseconds but still fires 30 times per second. Anybody know why Excuse me if it is basically obvious. Thanks, Devin The problem is that with an interval of 15ms you're very close to (or even below) the minimum quanta for the thread (i.e. the time slice it is allowed to run for before switching to another thread). In addition WM_TIMER messages are low priority and can be discarded (i.e. they won't stack up in the queue). Generally you should consider timers to be accurate to within +/- 10ms or so. They aren't suitable for ...Show All

• Visual Studio 2008 (Pre-release) streaming webcam video inside WCF

  bit of a newbie, I am trying to stream video from a webcam inside a web service. I am having little or no luck finding decent information about using webcams with WCF. Any information would be greatly appreciated. I have been doing a lot with WCF and video downloads and streaming lately - including writing my own custom message and encoder for optimized transfer of non-XML data. As Kenny says, the easiest approach would be if you could have a System.IO to return in your operation or MessageContract. Otherwise try to wrap the video resource in a custom Stream and use that. ...Show All

• Windows Forms Drag and Drop Label containing text into another panel

  Hi all, I was wondering if it is possible to do the following: I have a toolbar-like panel on the left of my form, on the right side of my form I have a larger panel containing nothing. In the toolbar are panels containing labels with text. I want to be able to drag such a panel to the panel on the right side and drop it there. I want it to be dropped on the exact location where I released the mouse button, that exact x-y position. Is this at all possible Any help would be appreciated. It can work with anything. The problem you are going to have is determining what to store when dragging and what to retrieve when dropped. For a picture box you can simply store the Image property as a bit ...Show All

• Visual Basic Simplest method to add e-mail to an application

  I am trying to find the simplest (& hopefully, most flexible) way to add e-mail capabilities to a Windows Forms application. I know I can use System.Net.Mail to send e-mail, but this requires some pretty specific information (server name, username, & password) that my application will not have access to. In an old VB6 application, I used MAPI to send e-mails, which I suppose is still an option in .NET. The benefit of using this is that MAPI handled all of the account information for me - it just "used" Outlook to send the e-mails. The only [minor] downside here was that my application required Outlook or OE to be installed on the computer - which is not really a problem where this application is distributed. Is t ...Show All

• Audio and Video Development uncompressed YUV to EVR

  Hi, I am writing a simple YUV media source to take in .yuv bytestreams and send it to the EVR. I have modified the MFT_Grayscale to act as a dummy transform to copy the yuv samples to the EVR. I am also using the playbackFX sample for the player. I'm having a problem with the player just showing a black screen, as if no samples are being sent to the EVR. I have verified that the samples are being processed in the dummy transform with the correct image size and attributes for my given yuv sample. I have tried other yuv samples and all just display a black screen, but the samples are being processed for sure. Is there any way to debug this to see if the samples are being sent to the EVR Or does anyone have any clues why this is happeni ...Show All

• Windows Forms How to Make Solution Explorer More Maneageble

  I'm in the process of converting a fairly extensive Access app to a Windows app and can see that there will be a couple of hundred classes of forms, datasets, reports, etc. That's a lot of scrolling, Is there a way to group classes in some way in the solution explorer such that, for example, all form classes ar in a collapsable tree Also, I am thinking of breaking it into different projects so that I do not have to recompile the whole thing every time I do a test run. Does anyone know of a good site on the web, or have any advice on these topics. Many thanks, Mike Thomas You can organize your project by creating folders.

• Game Technologies: DirectX, XNA, XACT, etc. Keeping game graphics the same size over different resolutions

  I implemented a virtual pixel system in Buttermilk to try and keep all the graphics of a game the same size no matter what the preferred back buffer resolution was. Unfortunately, due to accuracy problems with SpriteBatch.Draw's int-based coordinate parameters, cracks keep appearing between my tiles, and tiles sizes shrink / grow depending on how the float coordinate value of the tile translates to the int-based coordinate parameters. I've tried all different kinds of Math routines (Floor on the pos, Ceiling on the Size, Round on everything, etc etc etc) but nothing work as well as it needs to. So, I'm probably going to completely abandon the virtual pixel system. It's just not working at all. But, I still need some way to keep game ...Show All
