• .NET Development Audio recording in asp.net

Any help is appreciated.     You are unlikely to get an answer to your question on this forum. The people that watch this forum deal with networking, not audio recording.

• .NET Development Creating ASP Webpages / VS2003.Net

  I have Visual Studio.Net 2003 installed on my main development machine. I do not have IIS installed on this PC because I have a second PC running Windows XP Pro with IIS enabled on it and I wish to use this to host my ASP.Net development projects. I am finding it difficult to get Visual Studio.Net to create the project on the other PC. I have shared the folder wwwroot for full access on my LAN previously for my PHP development. I have had Visual Studio create the project but gave me some warning about been unable to configure the application root and saying it's probably something about WinNT/2000 mixed environments [It's wrong - Both PC's a ...Show All

• Visual Basic Virtual PC 2004

  I currently use WS 2003 for my operating system.  I am preparing to purchase a new AMD 64 bit  computer and am interested in suggestions for setting it up for both 32 and 64 bit operation.  Is the "Virtual PC 2004" technology a good way to for my 32 and 64 bit operating systems. Thanks, Fred Virtual PC does not support 64 bit Windows. But you can create two partitions on your hard drive, install a 32 bit OS on one and a 64 bit OS on the other. If you really need to, that is, because most 32 bit applications run just fine on 64 bit Windows. ...Show All

• SQL Server Why can't query analyzer be made to work for SQL 2005?

  I know my investigation is pretty light but it appears that DMO works fine against SQL 2005 (we use the same code to generate script against a SQL 2005 server that we do for a sql 2000 server). Why prevent query analyzer from being able to use the same DMO so that it works on SQL 2005. I really miss the simple ways of using query analyzer that I have become accustomed to and would love to be able to keep it in my toolbox foruse with both databases. Also why (when using query analyzer search, one of the best features that I miss) does it prompt you to install the stored procedure and then not work anyway sp_msobjectsearch . ...Show All

Thats what managed code is all about, so that your code doesnt interfere with other applictions. Look into unmanaged code. ...Show All
