  Hi, I'm trying to make OdbcCommands running in the background interruptible from a UI button. According to the documentation the OdbcCommand.Cancel() method does just that but the problem is how to invoke it, since it can only be called from the thread the command is running on and that by definition this thread is busy running the command. I tried outside a backgroundworker, using the example code supplied by MS : public void CreateMyOdbcCommand(string mySelectQuery, string myConnectionString) { OdbcConnection myConnection = new OdbcConnection(myConnectionString); OdbcCommand myCommand = new OdbcCommand(mySelectQuery, myConnec ...Show All

• Visual Studio 2008 (Pre-release) Data-binding to a radio button group

  Since RadioButtonList is now obsolete in the CTP release, what is the recommended method for data-binding to a group of radio-buttons   I don't want to data-bind each individual radio button. A radio button list is now achieved by styling a single-select ListBox control such that each ListBoxItem is a RadioButton.  An example can be found in the ExpenseIt Demo in the WinFX SDK. Using this new approach, you would bind to the ListBox. Cheers, -Jonathan ...Show All

• SQL Server Custom source adapter UI

  I am currently writing a custom source adapter that extracts data from a JD Edwards OneWorld system. In the custom user interface of the source component I need to allow the user to set a query (a custom property), and then refresh a list of output columns that will be extracted based upon that query (similar to the list shown in the advanced editor). My question is, can I apply the custom property change to the component and build my output column list without closing and restarting my custom UI form I understand that the IDTSComponentUI interface being implemented allows for transactional editing of the component, in that the changes t ...Show All

• Visual C# Best practice for exceptions thrown in BackgroundWorker?

  BackgroundWorker can pass back any error that occured during async as a property of the RunworkerCompletedEventArgs, .Error I'm not positive, but I don't believe this worked well until the final release version of the 2.0 framework. Regardless, If I throw an exception myself during async the debugger will stop and tell me that I have an unhandled exception--- F5 to continue and the method that deals with the callback takes care of the exception passed to it with RunworkerCompletedEventArgs. Since this works as it should in release builds, is there a way programatically or otherwise to prevent the debugger from nagging you that an ex ...Show All
