• Game Technologies: DirectX, XNA, XACT, etc. C# and soundcard

  Want to build a simple piece of equipment to do electrical measurements and display the results. As an analog => digital input device I want to use the soundcard. The main problem is: How to get the information out of the soundcard. I also want to use C# (if possible). The first question you should ask yourself is if it's possible to get your information into the sound card. Sound cards filter out low frequencies so you can't measure DC voltages. ...Show All

• Visual Studio Express Editions no subject

  can anyone give me an example as to how to connect and control something from a serial port.....something really simple like a light bulb..... hey maybe this..... I have a teddy bear which runs on batteries when you squeeze his foot he snores.... I would love to connect and control him by the pc any ideas...please Not a parallel cable - a serial port cable. In your original question you writes the serial port, and my answers is based on that. Do you mean the parallel port instead No it does not sound correct! If you want to start the head motor from the PC, you need an output. The serial port cannot drive the motor directly. You need to connect a switching transistor in parallel with the sensor in the teddy bear ...Show All

• Visual Studio Tools for Office Mysterious Add-in load issue.

  Its not exactly VTSO, I know but I'm desperate. I'm new to developing managed (C#) Add-ins for Excel and new to Visual Studio 2005 and very new to developing Add-ins in VS-2005. That said I've been trying to put together a little test case COM Add-in. I've followed the basic recipe as as detailed in ".Net Development for Microsoft Office" using Visual Studio and have gotten a simple COM add-in to work in Excel 2003 on my computer without a hitch. When I try to send said add-in to others it doesn't load up for them (though it should). Furthermore when they check their Excel instance's COM Add-in dialog, they see that Excel attempted to load the addin but failed (Location "mscoree.dll ...Show All

• Visual Studio Team System Get specific version not working after moving code from one team project to another

  I am no longer able to perform a "Get specific version" after I moved the code from one team project to another. I can see the history of all the files, but when I try to do a get specific version by date or changeset the "Latest" column in the source control explorer window shows "Not downloaded". This is very curious and alarming. Any help would be most appreciated. Jason, I'm sorry to hear you are having trouble with this operation. Can you confirm that the location of the item before the renames is also mapped in your workspace For example if the item was $/OldProject/dir/foo.cs and you renamed it $/NewProject/dir/foo.cs is $/OldProject/dir mapped into your workspace or just $/NewProject/d ...Show All

• SQL Server Getting the value of "SET ROWCOUNT"

  I'm writing an INSERT, UPDATE and DELETE trigger on table A that needs to insert rows into a table B. When a user issues a "SET ROWCOUNT" command to limit the number of rows, then does an insert, update or delete, the trigger is being limited to that number. It is important that the trigger NOT be limited to ANY specific number of records, but it is undesireable for me to just wipe out the current "SET ROWCOUNT" setting for the user without their knowledge. How do I get and preserve the current "SET ROWCOUNT" value from within my trigger, so I can cancel the limitation and then re-implement the setting once my work is done I cannot find any documentation specifying where the ROWCOUNT value is set (I ...Show All

• SQL Server Export / Import Aggregations

  Hello, Is there a way to export / import the partition aggregations The thing is - I ran the usage base optimization (+ using a bit of SP2 AggMgr.exe), but everytime I change the cube and redeploy, it overrides the aggregations and i have to rerun the usage base optimizer. Thanks, Haggai Good question. I dont know of any automated tool or way of adding aggregation desing into a measure group. Though I can see someone enhancing AggregationManager sample application to allow for loading aggregation design stored in file. Or copying aggregation design from one measure group to another. I might have some time doing that :) As for now, the easiest way would be to create a XMLA script of your old measure group and save ...Show All
