• .NET Development DVD Burning component

  I'm currently using an obscure ActiveX control (DVDWriterPro2) for DVD burning in my app.  I have been having stability issues with this control and would prefer something that doesn't have to run on a visible form and is a pure .NET component.  I know Nero has some sort of SDK available and Roxio licenses their Authorscript burning technology (probably at a premium), does anyone have experience in this area Thanks,     Luke Unfortunately this only supports CD's.  I hear Windows Vista will have native DVD burning but as far as I can tell thats still about a year off. ...Show All

• Visual Basic How do I serially send characters that have an ASCII value over 127?

  I have been working with the new "SerialPort" tool provided with .NET Framework 2005 through VB. As an example, I am trying to send the following string, Chr(2) & Chr(152) & Chr(0) & Chr(3). However it keeps replacing Chr(152) with a Chr(63) (3F-a questionmark). I have tried changing the encoding to Unicode or UTF8 but that adds other characters that I don't want. The example provided is just a sample of what I may have to send. Some strings are 70 characters or more in length and could be virtually any combination of characters. How do I send the exact string I have constructed. I have done many applications using the ...Show All

• Visual Studio Team System Max 260 characters in path + projectfolder-hierarchi + programname?

• Visual Studio set CustomBeforeMicrosoftCommonTargets=$(MyEnvVar)morepath/my.targets

  set CustomBeforeMicrosoftCommonTargets=$(MyEnvVar)my.targets Why does the above not work with CustomBeforeMicrosoftCommonTargets and MyEnvVar both defined in the environment I would think that msbuild would expand the above value of CustomBeforeMicrosoftCommonTargets just fine before using it, but it doesn't seem to work. You should change your environment variable to: set CustomBeforeMicrosoftCommonTargets=%MyEnvVar%my.targets That way the shell will expand out the environment variable first, then MSBuild will get the expanded version of it.

• Visual Studio 2008 (Pre-release) PeerChannel throttling controls?

  How does one properly throttle a PeerNet network when messages are pouring in faster than the receiving nodes can process them I'm trying to prove whether or not PeerChannel would make a good foundation for publish-subscribe style messaging that is reliable and robust enough for an enterprise. My initial testing has been very positive. PeerChannel is looking to be super-reliable so far. Sending 10,000 messages in a 5-node configuration: 0 message loss, 2,500 msgs/min to 4,000 msgs/min per receiving node Sending 100,000 messages in a 5-node configuration: 0 message loss, 2,500 msgs/min to 4,000 msgs/min per receiving node Send ...Show All

• SQL Server Execution of Package failed

  I am trying to design package which would copy all tables and stored procedures from one server to another. It used to be simple task in SQL 2000, there was wizard. However the new wizard does not work... I wrote SSIS package, but when I execute I get the following error: "Can not apply value null to property Login..."

I am considering to rollback to 2000. Very frustrated with the new one...          There should be more to the error message than that. Please can you copy the ...Show All
