• Software Development for Windows Vista DirectShow within Direct3D render loop

  I am developing a 2D/3D interface using Direct3D. I am trying to also include a video window within the interface to display live TV from a tuner card. I am using VMR9. The problem I have is that the video is flickering, seemingly caused by the drawing loop. After I call D3D Present(), I have to tell the VMR9 window to repaint itself using RepaintVideo(), otherwise the video does not show at all. I am very new to DirectShow and any help would be greatly appreciated. Thanks. Great, how do I specify a clipping region on a 2D interface. For example, I don't want anything to draw in RECT(100,50,420,290). ...Show All

  Hi All, I tried to draw few meshs in game. But i has some textures problem. The problem is a meshs collistion another mesh, textures alpha chennal has some problem. Below is capture screen. Who can tell me why How to fix this problem http://hk.geocities.com/brian_tsim/error.PNG Best regards, Well, I’m not so sure the performance hit is due to the lack of ZBuffer optimization. Yes, that will have an impact, but not so much. The slowness you experimented is probably due to the costly alphaBlend operation. Anyway, In my engine, I’ve got thousands of trees, sorted and rendered in back to front with alpha blending, and it runs fine. ...Show All

• Visual Studio 2008 (Pre-release) Creating a brush from the text?

  WHat's the easiest way to create a Brush from some text at runtime Thanks, Douglas.Your code worked almost as is. I just needed to close the Drawing Context. Here's tested version:   DrawingGroup group = new DrawingGroup (); DrawingContext dc = group . Open(); dc . DrawText( new FormattedText (sText , CultureInfo . GetCultureInfo( "en-us" ), FlowDirection . LeftToRight, new Typeface ( "Verdana" ), 10 , Brushes . LightBlue), new Point ( 100 , 100 )); dc .

• SQL Server How to insert into Temp Table

  i have temp table name "#TempResult" with column names Memberid,Month,Year. Consider this temp table alredy has some rows from previuos query.

• Game Technologies: DirectX, XNA, XACT, etc. Geometry Shaders - Multiple Streams

  Hi, I have two questions regarding geometry shaders: 1) Can a geometry shader write to a Stream Out while passing the data down the pipeline at the same time I've read such indications, but I can't seem to find it documented anywhere. I.e. a dynamic particle system where particles are added to a point stream out AND rendered in one pass. 2) Can a geometry shader have multiple output streams I.e. a dynamic particle system where particles are added to a point stream out, while triangle point sprites are sent to the rasterizer (in one pass, that is). Thanks! 1) Yes, you can stream out and rasterize at the same time. 2) Yes, you can have up to four streams as long as you stream only single element ...Show All

• .NET Development I'm fairly certain I'm losing my mind....

  For the past 3 days, I've been spilling my brains all over my keyboard in an effort to do something that should be ridiculously simple.... What's really driving me crazy is the fact that I've done it before... Here it is: I have a datatable in MS Access. In an effort to copy all of it's records to a table in SQL that I can access and better manipulate, I created an SQL Database in my Visual Basic program and made a comparable SQL Table. I gave all the columns identical names and comparable data values as the columns in the Access table. Now, I just want to copy the records from the Access table directly into the new SQL table. Here's the catch. I'm doing all of this through the DESIGN interface because the last line of ...Show All

• Visual Basic Shutting off a remote machine

  Hi guys, I came across some code that suggested that in order to shut down a remote system, the following code can be used "shutdown -s -f -m \\Systemname " But when I tried it, it showed that the network path was not found.

• Visual C# generic methods

  I want to be able to implement a strongly typed IClonable, so that I can clone based on lineage. public interface IClonableObject { T Clone<T>(CloningFlags flags); // flags specify level of cloning } so that I have something that looks like: public class Foo : IClonableObject, IFoo, IBar { string bar = ""; public string Bar { get { return bar; } set { bar = value; } } T Clone<T>(CloningFlags flags) { switch(flags) { .... case CloningFlags.ShallowCopy: { return (T)MemberwiseClone(); } } } } and can use it like: Foo f = new Foo(); Foo b = f.Clone<IFoo>(CloningFlags.ShallowCopy); I know this syntax (and most likely logic) is wrong. tha ...Show All

• Visual Basic IO.FileShare.ReadWrite What does it buy you

The question is just what that means Within the program Within the PC regardless of file location Accross the network if the file is on a shared resource I am updating a file without the benefit of a database handler, but need to keep te rest of the world from working with it while the extemely quick and relatively rare update is going on.

• Visual Studio Express Editions Mock CD Root

  Sorry for the poor Subject Title I'm going to try and explain this as best as I can. What I'm doing is making an autorun.inf program. Well that's easy. 6 minutes of programming and I'm done. But what I want to do is make this a little more that just an autorun program. I'm going to make it so you can add directories and files then "build" the folders. Well I know how to do this too, not a real problem. Now what I do need help on is this: autorun files are placed on root of the CD, But what my program does is gathers all the files and creates a Folder for them. The folder (project folder) is like the CD. Now let's say setup.exe is the autorun program. Well to add this as the open= the user will browse for this file. But when the f ...Show All

• Visual Basic Add and remove data from file

  Is t possible to: Add data to a certain offset in a file without overwriting original data from that offset, thus expanding the file Remove data from a certain offset and length in a file, instead of making a new file of the two desired parts of data from the original file Thanks! Sure performance may be an issue with files this size and the stringbuilder class may be the best option. Also remember windows uses virtual memory, so it will page items in an out of memory if you dont physically have 100Mb free in your machine at the time.
