• Game Technologies: DirectX, XNA, XACT, etc. Default pixel shader?

  I fear I already know the answer, but is there any way to use a 'default' pixel shader This used to be done by specifying PixelShader = null; in the .fx file, but this doesn't work any longer. I bet a lot of games will do just fine using BasicEffect for all their rendering. If you want to do fancy graphics stuff you will obviously need to create custom effects, but plenty of interesting games can be made just with simple lit+textured models! You could easily emulate any Playstation1 level of graphics, and PC games like Quake2, entirely using BasicEffect. ...Show All

• SQL Server DROP DATABASE problem

  I am facing a trouble with DROP DATABASE command. Let me explain it this way: Actually I am building an installation package which executes a series of SQL scripts to do the database changes on the target machine. Steps are briefly listed below: 1 - Create a database with simple CREATE DATABASE command 2 - Restore the database created above with RESTORE DATABASE command (with replace option) 3 - Configure other objects such as logins etc etc. Now, everything works fine as long as all the scripts execute correctly. However, I have seen instances when RESTORE DATABASE fails with "timeout expired" error. Well, I overcame this problem by simply increasing the timeout limit. But in that course what I observed is that when a restore da ...Show All

• Smart Device Development modal form will not close

  I have a C#, .NET Compact Framework 2.0 SP1 application. I have encountered a recurring problem where modal Forms displayed using the .ShowDialog() method sometimes will not close when their Dispose() method is called. When this problem occurs, the modal Form remains on-screen as the top-most window but is completely unresponsive and cannot be closed. This problem is actually worse than an application crash because the only way out is to use the Settings > System > Memory > Running Programs control panel to ‘Stop’ the application. The modal Form in question does not have a CancelEventHandler for the ‘Closing’ event. Is this a known problem If so, I urgently need a fix or work-around for this problem. So we have ...Show All

• Visual Studio 2008 (Pre-release) DoFinalConstruction?

  Hey guys, Can someone shed some light one what DoFinalConstruction does Any chance that we can make that method virtual :) Would be very handy for doing setup construction on entity objects (putting in default properties, etc...) Thanks! Mike As an aside... is there a reason this method is not marked "virtual " Maybe I'm missing something, but I thought methods that aren't marked virtual aren't supposed to be overriden That is, it's intention is not to be overriden. Is this just an oversight or the actual intended design Thanks! ...Show All

• Audio and Video Development Protected Content (PMP) and tee node

  Is it possible to play a protected media file in a topology using the tee node. I modified the ProtectedPlayback sample and I get MF_E_TOPO_UNSUPPORTED error after setting the topology. Thanks! I inadvertently omitted a detail here, and also I thought of a possibly easier option. If you're going to go the dummy MFT route, you'll need this dummy MFT to require that its input type be uncompressed audio (cf video). The reason you have to require uncompressed media is to force the topoloader to insert a decrypter _and_ a decoder between the source node and your MFT node. At least in the case of WMDRM-protected content, the decrypter needs to be directly upstream of the decoder, since we set up a secure ...Show All

• .NET Development Compatibility

  Hi, I want to know whether vs.net 2005 application will run in .net framework 1.1 (are they compatible ) Regards, Durga. Hi, For Windows application, it runs in the client machine so to host and to provide run-time platform to the application; Client must have .Net framework installed. (Windows XP has installed .Net framework 1.1 with it so no need to install it explicitely but a prior OS needs to install it before you can run the application) Its very diff in Web application, where it runs on Server machine and client only requests to webserver and web server does process and returns client the results in HTML form so in this case server needs to have .Net framework installed but not client.

• Windows Forms Custom User Control (drawing outside the parent Region)

  Hi, I am trying to create a custom combo box, whic is a combination of textbox, command button and a datagrid. I am able to implement pretty much whatever was required. I ran in to a problem when the user control is contained in a Group Box, thus on the drop down event, my Grid (which is acting as the drop down list) does not show properly as it cannot go beyond the boundries of the Group box. Is there a way I can make my user control act as Top most Window so it draws over every other control. It tried using Function SetWindowPos Lib "user32.dll but it doesn't seem to work. Any help would be appreciated. Thanks Well what I meant was that a Group box can contain other controls beside my Custom control so as i ...Show All

• Visual Studio 2008 (Pre-release) The futher of WPF?

  Hi all Is it true that none of the application that ship as part of the windows vista OS use WPF And if so, what is that saying I'm trying to develop our companies first "for Cash" app using WPF. Is MS really committed to making WPF the new programming model If MS can't afford to use WPF, how can I (It is the state of the tools , more then the readiness of WPF, that really make me ask this question.)

• Windows Forms DataView Sorting

  Hi, I have two combo boxes and a DataGridView. The two combo boxes are going to serve as filters for the DataGridView. When the form loads a stored procedure is called to return a number of records to be displayed in the DataGridView. The grid can then be filtered by using either one of the combo boxes. If the selected index changes on either combo box a DataView is created from the DataTable holding the data from the stored procedure and a Row Filter is a applied depending on what the Selected Item Value is. All this works great but the problem I have I need to combine the two filters into one. I.e. if you want to filter the data to show only today’s events and then filter it again to only show a certain type of event. ...Show All
