• Visual C# Question about threads

  I created a socket and am asynchronously listening to a TCP port. This calls a method in another thread when a connection comes in, which puts the data into a buffer and sets a boolean variable to true. Is it safe to fill a buffer and set a boolean value from this other thread If so, how can I set an event when a boolean variable is set to true (in the main thread) to alert my code that data is there Or is there a better way to do this Thanks for any help. From the sounds if it you are working to implement a Producer/Consumer design pattern ... the only problem with your implementation from the sounds of it is that it is not thread safe. Once you've made the operation thread safe so that no two ...Show All

• Visual Studio Team System VS 2005 IDE Create SQL Store Porcedure like 2003 IDE

  I use to have an option within the 2003 IDE to generate SQL Stored Procedures, however using the new 2005 IDE and SQLDataSource I can only generate dynamic SQL stagements or refer to existing Store Procedures. Can 2005 IDE generate SQL Stored Procedures If so how I have looked through the MSDN library and How to's for this. Doug DrDrain, You won't be able to create a stored procedure from the SQLDataSource wizard in VS2005. But from VS2005 IDE, you can create the stored procedure from Server Explorer (View menu-> Server Explorer).

• SQL Server db_dtsadmin role

  Our DBA has given me access to MSDB on the SSIS service on one of our servers as db_dtsadmin. When I try to connect to the server using Integration Services in the connect drop down menu, I get the following generic error msg: connect to SSIS service on server 'xxxx' failed: access is denied. I'm told this role should be sufficient to give me access. Do I need other server access roles to use in conjunction with db_dtsadmin or are we missing something really easy here. Thanks. Thanks. We're still trying to work on this. We followed the instructions on the link (connecting to a remote integration services server) but I still can't connect and still receive the same generic 'access denied' error me ...Show All

• SQL Server Database Location

  Got a couple of questions 1. If you are managing databases in SQL Express with SQL Server Managment Express CTP, why doesnt VBE place the database there where you can see them I can create a database inside SQL Server Managment Express CTP and view its tables, relations,etc. from within SQL Server Managment Express CTP, but when I make a database with VBE it does not show up in SQL Server Managment Express CTP. Also the database that was made inside SQL Server Managment Express CTP cannot be seen from VBE.

• Windows Live Developer Forums Bug in a Route.Itinerary.Segment.Distance

  Hello people, while i was debugging an application i'm working on, i found a bug (i guess so...)in the distance info in a route segment; you can test it at http://local.live.com/ (using shortest time and miles options). The bug is in the 9th segment between Washington [Washington, D.C.], District of Columbia, United States and Miami, Florida, United States. The total distance of the route is 1062.9mi, but the distance in the previous segment is 794mi!! However, if you query the route between that segment and the next one, the distance is correct... I hope it helps to correct it. greetings Dario Aznar - Argentina Hi John, someone out of this forum explained it to me that i was m ...Show All

• .NET Development Remoting timeout issues

  Are there any known workarounds for the really annoying lengthy remoting timeouts on down servers This is particularly a problem when using .Net remoting and the server isn't available, it can take up to 2-3 minutes for the line of code to timeout when accessing a remote object. I have tried implementing a Ping class before I access the object, but sometimes this just doesn't work if the server is in the process of shutting down... Obviously having an application hang for that long is unacceptable.. I am threading everything however my application will not cleanly close if the thread is hung waiting for a socket timeout. A sample for you.. correct, if the machine is in the process of booting then a ping solution could gi ...Show All

• SQL Server Dymamic connection strings in SSIS...

When I go into my configuration file, I can see the connection string, and when I go into the advanced properties of the connection manager, under the "Named ConnectionString\FileName" property, I set the property value to the name of my configuration file, but when I test the connection I get an error that the connection string property has not been initialized.

• Visual Basic Timer Events Not Firing in Windows Service

  Hi All: I am trying to upgrade my vb.net 2003 windows service project to vb.net 2005. The 2003 project runs great and the timer events fire; however, the 2005 timer events in 2005 will not. Same code - just compiled with different versions of vb.net Any ideas Doug. One thing you may also want to check is that the timer is the 'correct' timer so to speak. The system.windows.forms.timer does not work for me correctly and I normally use the system.timers.timer instead. You can manually add it to the toolbox using add/remove since it is not there by default. ...Show All
