• Visual Studio 2008 (Pre-release) Is it OK to implement IValueConverter on the custom control class itself?

  I have a custom control that displays a lot of lines as a Polyline (to display a histogram ;-)). Therefore I implemented a IValueConverter, that converts my histogram to a PointCollection. My question is, is it OK to implement the IValueConverter on my custom control class itself as I sometimes need some more information during the conversion that is only available in the control class It is ok to implement IValueConverter on your control class, but i wouldn't recommend it. IValueConverter is a concept used to abstract UI from the underlying application logic, and by making your control implement IValueConv ...Show All

• SQL Server Why is there no warning if an input to an Aggregate component is not sorted

  All in the subject.   Donald Farmer wrote: Anyone here. We have this as a possible refinement for the future, Jamie. In fact there are a range of optimizations that sorting can enable, such as Max and Min aggregates, and Top-n, Bottom-n. Something to look forward to! donald Cool. That makes sense - thanks Donald! ...Show All

• .NET Development C# "Platform" related directives

  Not sure if this is the right forum for this... I have a solution that has muliple projects wherein each project targets a different platform such as WinXP/Win2000/Win2k3, WinCE, PocketPC I want to be able to maintain the same code base (only the "Form" is different). However, there are a few nuances across these platforms and so my code does not compile. Are there any platform specific directives that will allow me to do this Shiv. Defining my own symbols is not really going to work for what I've asked. But thanks anyway. I don't believe VS has this kind of thing. Shiv. ...Show All

• Visual Basic Error with sockets and threads

  Hi I am having a persisting problem with an application that I am developing. I've made a TCP Server class with a thread for listening incoming connections and a thread for polling for received data from the "accepted" sockets and also disposing them. I have 3 puiblic events raised from within the threads, one for notifying the acceptance of a socket, one for Received data and one for a closed socket. The application seems to work OK, but if I try to connect and then disconnect with the client application for a non-predictable number of times, I get an unhandled NullReferenceException. The threads stop at the following locations. T ...Show All

• SQL Server "Renaming package" dialog

  I created a new SSIS solution, right-clicked the default name "Package.dtsx" (under SSIS Packages), then renamed it. A dialog appears asking "Do you want to rename the package object as well" What are they referring to and what are the consequences of doing/not doing so Barkingdog In Visual Studio you rename a file - the *.dtsx file. However, the SSIS package is an object in the file. So if you don't rename the object you could have a package file called MySuperPackage.dtsx containing a package object called MyOldPackage. Try saying no to the dialog once and check the name prop ...Show All

• Visual Studio Team System Web Test - Any way to compare an Extracted value (Context Variable) against an expected result?

  Hi, Is there any way to compare an Extracted value against another expected value without using coded Web Tests Thanks The extracted value can be compared without using coded Web Test. It can be done by combination of Extraction rule and Validation rule. The "Context Parameter Name" entered in extraction rule can be used in the validation rule as expected value. It has to be taken care that the context parameter name should be appended by {{ __ }}. Eg: If Context Paramerer Name is UserID then {{UserID}} has to be entered as expected value in validation rule. ...Show All
