• Visual Studio Team System Workaround:: Content Files Bug

  This *release* version of VS2005 is dog and I just can't take it anymore. Here is the 3rd bug I've found (I never found any at all in Everett)... Create a test project add an app.config file to the root of the project add another app.config file called reallyImportantFile.config to the root of the project set reallyImportantFile.config to BuildAction=Content and CopyToOutputDirectory=Copy Always compile the project and peek out /bin/debug (it is there) write a unit test that checks to see if the file exists (File.Exists(fileName)) watch the test fail BECAUSE TEAM SYSTEM DOESN'T MOVE THE 'COPY ALWAYS' FILES INTO THE OUT DIRECTORY ...Show All

• Visual C++ calling managed dll from native dll and keeping a static ref

  What issues should I be aware of when doing the following: End scenario: Native dll needs to hold a static reference to a managed class (written in c#) throughout the lifetime of the native dll. I have written a slight wrapper in managed c++ (technically c++/cli) in whidbey. This all seems to work fine and dandy, but there always seems to be a "gotcha" in the managed c++ world. When I compile I get this warning: Warning 1 warning C4251: 'RequestHandler::wrapperClass' : struct 'gcroot<T>' needs to have dll-interface to be used by clients of class 'RequestHandler 1. Can this be ignored in this case since the native class shou ...Show All

• Visual Studio Team System Sampling profiler: is there some way to see a disassembly view?

  I just found out about these tools today, and I'm pretty impressed. Nice job! I was wondering if there's any way to see disassembly (e.g. with number of hits on the instructions) ... And/or is it possible to somehow extract the actual raw data (e.g. EIP's, module info: base-address, version) from the .vsp thanks much, Jon You indicate that you will have source line profiling in the next version.  Can you provide an expected date for the release of the next version ...Show All

• SQL Server Dialog Security and Message Encryption

  I understand that Dialog Security + certificates can be used to encryption individual dialogs. I have several demos working now that do just this.However, I don't fully understand exactly when the messages are encrypted, and if they are ever written to a queue on the initiating service prior to being encrypted. I want to make sure that admins can't simply query the transmission queues to get clear text messages, because I have strict requirements that I encrypt all personal data that is stored anywhere in a database. BOL is a little unclear on this topic. The relevant doc reads: For a dialog that uses security, Service Broker encrypts al ...Show All

• Audio and Video Development blend image use VMR9

  I blending an image on the video use VMR9,when the video is rendered in it's native size,the image is ok,but when the video is resize(such as 320X240 to 640X480),the image is blured. What is the size of the image that you are blending I assume the native video size is 320x240. When you stretch it to 640x480 you should see slight blurring (or specifically aliasing) of the video also. Are you seeing that the image is getting blurred worse than the video Sumedh ...Show All

• SQL Server File System Task: Move/Rename

  I can use the File System Task to Move a file from one directory to another and to rename a file, but is there a way to do this in one step, i.e., move file named 'c:\foo.txt' to 'c:\backup\foo_bkp.txt' OK, maybe I'm being dense ... but how I have both Source and Destination set to variables. The "Move File" facility only accepts a directory as the Destination because when I coded it with a new file name, I got an error due to the destination file name being ["DestVariable"]\["SourceFileName"] so it looked like: c:\backup\foo_bkp.txt\foo.txt ...Show All

• .NET Development Load Balancing Socket Connections

  Hi, I don't know if this is even possible but here is the scenario I have: I have a server/client application connected via TCP.  Lets say I have 5 clients applications.  I have 2 server applications running behind a load balancer.  Since it's TCP, lets say 2 of the clients make a socket connection to server 1 and 3 of the clients make a socket connection to server 2.  Can I have server 1 send a message over the socket connection to each of the clients   The clients make the connection to the server...so I can't just open another socket connection from the server to the clients... Make sense Is that possible ...Show All

• Visual Studio 2008 (Pre-release) Pre/Post Operation Invokation Extensibility

  I am looking for a way to set up some state in thread local storage immediately before operations are invoked and then to clean it up immediately after they have completed. (i.e. the pre/post operation code must run on the thread used to service the request). What would be the best way to do this Thanks. Frank, The IOperationBehavior and IOperationInvoker interfaces will do it for you. The following are the major steps: 1.
