      1. POIs there a reason for C#'s reuse of the variable in a foreach?

    1. COAnother comment agreeing with Hans. I had a related problem in regards to drag-drop from Windows Explorer to WinForms app. If the app was running as Admin while the Windows Explorer was running as default user drag-drop just would not work due to UAC enforcing security on clipboard operations. You might find a work-around by playing around with which user runs the service for the Steno input.

    2. CO1. The problem in this case is that the worker thread is the I/O-thread and blocking it will (eventually) time out the session on the server. Also, all updates received are critical in this application so they must be queued one way or another. 2. You are correct that execution order for BeginInvoke is guaranteed but I don't think they are guaranteed to be atomic. For a more detailed explanation: http://www.codeproject.com/KB/cs/begininvoke.aspx 3. I thought MessageBox always should be used in main/GUI-thread like other GUI

    3. COThe message box is displayed by a listener far down the datastream that listens for error message from a remote trading system and must be a popup. A possible solution could be to do the MessageBox.Show itself using BeginInvoke, it does not need to be synchronous with receiving the update. What confuses me is that MessageBox modality behaves differently when Invoked (main message pump stops) than when it originates from events inside the main thread or using BeginInvoke (message pump continues processing other events even while the MessageBox is shown).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
