• Audio and Video Development s

  Hi. I'm sending "dummy sample" when there are no data to send from source. butRequestSample() come buck so quickly and keeps spining until data are ready. It's really waste of CPU power. What should I do to stop this I'm trying to build something like a LiveTV player. Thanks. Kasumi. I'm guessing that you have an MFT downstream of the Media Source that interprets these dummy samples as "no data". If you give this "no data" sample a duration, then your MFT can just produce that duration's worth of silence (audio) or repeated frames (video) and return MF_E_TRANSFORM_NEED_MORE_INPUT from ProcessOutput only when those have been exhausted. This will keep MF f ...Show All

• SQL Server Is it OK to Copy Database Backups to Tape Using Compression?

  Hi, I back up SQL Server 2000 and SQL server 2005 databases to hard disk using the SQL Server Backup Wizard and maintenance plans. Then, I copy the resulting backups to tape using third party tape backup software and compression by the backup software and hardware. I do not use the SQL Server Agent available for the third party backup software. Is this acceptable, or does the compression performed by the third party backup system introduce opportunities for database corruption or other negative effects Thanks Hello, This is completely acceptable - provided of course that the software you are using is reputable and that you have tested restoration succesfully. Cheers Rob ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SetData / Mip

  There are a few versions of the SetData function. Some that take a mip level and some that don't. I'm curious... If I have a multi-mip texture and I use one of the SetData calls that does not specify a mip level does it write to mip 0 and then automatically generate the other MIPS in the same call or does it simply write to mip 0 ...Show All

• Microsoft ISV Community Center Forums CRM 3.0 - Insert template & Subject is truncated

  When using CRM 3.0, every time you insert a template, it truncates & replaces the original subject text (which includes the required tracking identifiers). Is there a way of turning this feature off - it didn't happen in 1.2, so unsure why it appears to be the new default. Cheers Matt ...Show All

• Visual Basic Fill bound combo

  Still havent fiqured this one out yet. Say if you have a combobox that is bound, and you want the drop down to contain data from another tables column. How do you do that Davids Learning To add new items, you would need to add them to the datasource that the control is being bound to and not the combobox directly. So if you are binding to a datatable - then add the items to the datatable and they will appear in the bound control. Binding to a datatable/dataset is not a problem as this is a local copy of what may be a retrieved from a database, as long as you dont run an tableadapter update method with this dataset these addition wont be persisted back to the database. ...Show All

• SQL Server Scheduled SQL Server Agent SSIS Package Job Problem

  HELP! I have been banging my head against a brick wall on this one all this morning AAAAAAGGGHHH! 1. I have an SSIS package that runs a simple SQL script and then updates a few tables by downloading some XML of the web. It runs fine when I kick it off manually under SSMS. 2. I created a SQL Server Agent job to run it every day. This always fails. The error information in the log is useless ("Executed as user: domain\user. The package execution failed. The step failed." - I had already figured that out!). It fails almost straight away, and when I enable logging for the SSIS package, no info is ever logged (text file, windows event log, whatever). 3. Out of desperation I have changed Agent to run under the same domain user ...Show All

• Visual Studio Tools for Office Combining RS2005/C#/Excel, Hit a Snag

  Hi All. Essentially, what I'm trying to do should be really, really easy. In reality, it's turning out to be anything but, and I think I may be in that developer funk where the answer is right there but you ignore it... So I have this app that takes user inputs in a web form, cooks up some data based on those selections, and then returns the results in any of several reporting services reports. Enter a new requirement where the client now wants to be able to dump the data directly out of the web page into Excel with a slightly different schema. So - here's what I did: I created a project for the Excel document and its population logic. It tests out great when standing on its own. The web form/rs05 project, too, works great on its ...Show All

• Visual Studio Express Editions Can you save the output into notepad

  When running console application can save the variables and the output on the screen into notepad If you would like to store the output from any printf or cout calls to notepad, you can redirect the console app to a text file. This can be done by running the app with the '> <filename>' syntax. Ex: YourApp.exe > temp.txt This will put all output into temp.txt. You can set the command line via the project settings so that Visual Studio always runs it with the given command line. -Reza ...Show All

• SQL Server Insert row in table with Identity field, and get new Identity back

  I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table). What is the most direct way to do this in SSIS TIA, barkingdog P.S. Or should I pass the identity value back in a variable and not make it part of the data stream re: We do have a design pattern for highly parallel key generation that may (but may not) be in the next version . Either way there will be a paper on this at some point. Thanks for the post. It kept me from heading down the wrong path trying to use @@IDENTITY. Any progress report on the Design Pattern or the paper ...Show All

• .NET Development .NET program in autostart

  I've created a very simple "hello world" program with C# 2.0 (VS2005) and placed this program into the autostart folder. On startup the console window shows up, but it remains empty for several seconds. Only after about 5 seconds the "hello world" message appears in the console. I tested the program on a different computer (the hardware is pretty much the same) and the delay is much shorter (about 1 sec). I guess that it has to do something with the initial setup of the CLR. How can I speed this up I did another test: I reduced the program to the absolute minimum (nothing is outputted, there are no dependencies): namespace HelloWorld { class Program { static void Main(string[] ar ...Show All

  Nearly every time I look for help on a topic I get this Windows Install message.

I'm using VB.NET 2002 When you installed VB there should have been an option to "COMPLETELY" install the MSDN!

• 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
