• Visual Studio 2008 (Pre-release) MediaElement and Media Player

  Does MediaElement work with Media Player 11 (Beta) If not, does anyone know how to install Media Player 10 after having 11 installed I uninstalled 11 but get an error message, when trying to install 10, that there is a newer version installed! Thanks John MediaElement will not work with WMP11 on XP. Getting WMP10 to install after installing 11 is beyond my range of experience. Sorry I couldn't provide more help ...Show All

• SQL Server Error: Transaction context in use by another session

  I am programming in ASP and SQL server. I am using this tag <% Transaction =Required %> to do the transaction. And it woks well, but the problem is that sometimes I get this error: "transaction context in use by another session" ... It's really weird because it only happens in the same row. If choose this row to be shown I get that message, but if choose another row I get result with no error. And if take out the tag <%Transaction... I don't get any error. I've searched in other forums about this error, and one guy claims that there is a bug in the MTS and there is no way to solve the problem. Actually, the transaction is done only by using this tag <% @ Language ...Show All

• Visual C# ignore mouse down event

  I'm new to C# programming, learning it for pleasure on my own time. As an exercise, I'm creating a simple Windows program that 1) takes the mouse-down event as an 'anchor' point, 2) while dragging the mouse around continually draw a line from that anchor point to the current mouse position, 3) once the mouse-up occurs, shrink the resulting line down automatically until it disappears. Not too hard, and it works perfectly fine. My problem is that I do not want the Form to accept any mouse-down's while the shrinking logic is occurring. Currently, while the line is shrinking, I can do some more click-and-drags, and once the shrinking completes, those subsequent lines are drawn/shrunk in like fashion. I want to effectively ignore any mouse- ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Learning Direct X

  I have tried to learn direct x with several online tutorials, but failed. I have decied that I need to learn from a full book. I consider my self a good programmer. There are plenty of book centered around making games, but this is NOT my intention. I want to learn the basics and the advanced of direct X, from the ground up NOT from the perspective of making games. I want a book that is based on the .net 2.0, I dont wish to learn techniques that are already outdated. The book needs to include advanced topics such as how .x meshes actually work, ect. I would really appreciate any book suggestions, thanks ahead of time. David Weller - MSFT wrote: a book on native C++ DirectX. The Direct3D Grap ...Show All

• SQL Server VERY large binary import/export headache

  Hi, I am currently importing (and exporting) binary flat files to and from Db fields using the TEXTPTR and UPDATETEXT (or READTEXT for export) functions. This allows me to fetch/send the data in manageable packet sizes without the need to load complete files into RAM first. Given that some files can be up to 1Gb in size I am keen to find out a new way of doing this since the announcement that TEXTPTR, READTEXT and UPDATETEXT are going to be removed from T-SQL. I had a quick foray into SSIS but couldn't find anything suitable which brings me back to T-SQL. If anyone knows a nice elegant way of doing this and is prepared to share, that would be grand. Thanks for your time, Paul The "image" type is basically been changed to & ...Show All

• Visual C++ How to make dynamic 2D arrays?

  Is it possible to have a dynamically sized 2D or 3D array For a normal 1D array, I have 2 methods: 1) create a pointer to a variable, then initializing it with a supplied size: int *iTemp; iTemp = new int[100]; 2) use a CList. CList<int,int&>iTemp; But these methods fail when I try to make a 2D array. i.e. iTemp = new int[10][10] \\not possible Is there a way to achieve this instead of CList I assume by dynamic you mean ability to change size typedef std::vector<YOUR_TYPE> DIM1; typedef std::vector<DIM1> DIM2; typedef std::vector<DIM3> DIM3; DIM2 array2D; DIM3 array3D; use std::vector::push_back or std::vector::resize to change dimention size.

• Visual C# Allow generic method only for a few types (int, string, bool, float, etc.)

  Hello, i have currently a little problems with generics. I wanted to make something like that, which is no valid c# code: void MyMethod<T>() where T : string || int || bool || float || short || byte || uint || ushort || long { ... } But it is not possible to use types like int or string after the where keyword, because the string class is sealed and the valuetypes like int are no classes. I made a workaround, but I'm not very happy with it: void MyMethod<T>() { if (typeof(T) == typeof(string) || typeof(T) == typeof(int) .... ---- } This code gets not optimized by the JIT compiler (I looked in the assembler code), but its really important, that there is no overhead at this place. And i can't imagine, that this ...Show All

• Visual Basic VB2005: Startup Form / Splash Form / Application Startup

  Hi, This is driving me nuts, I have a Startup Form defined and a Splash Form defined in the applications properties. in the Application_Startup event, I have some code to do some initial checks, which will then be used throughout the applications lifecycle as well as to change the duration of the splash screen and change some of its contents. Now according to MS's code comment the Application_startup should fire before the initial forms are displayed. This does not happen the Splash form is being called before the application startup is being executed, so it is missing the initial code checks and doesn't do what it should...... Is this a bug what can i do to work around this Cheers, Dave ...Show All
