  hi, I got a big problem concerning updating my tables, I have a program with 2 bindingsources and 2 bindingnavigators They use the same dataset,but a different adapter Updating with my first bindingsource works perfect,like a charm, but when trying to update with the second bindingsource,it fails.

• Visual Studio 2008 (Pre-release) Handling events generated by Contents of ContentControl in a parent of ContentControl

  Hi, I have a control inheritted from ItemsControl which contains a number of specialized ContentControls. I would like to handle all the events (say, the MouseButtonDown events) generated by the Content of the ContentControls at the level of the parent ItemsControl. Obviously I can override the OnMouseButtonDown method in the ItemsControl, and, thanks to RoutedEvents, I will recieve all the events generated within a ContentControl. The problem is that the RoutedEventArgs.Source property is usually an item within the ContentControl rather than the ContentControl itself. What is the best approach for amalgamating events generated by the ContentControl and its contents I don't really want to define new RoutedEvents just for this purpose ...Show All

• Visual C++ How to catch MFC Application error causing application closing

• Visual C# Time

  Okay, so I am trying to make an alarm clock program for computer, to familiarize myself with C#. What I need help with, is I have the dateTimePicker tool for setting the alarm, and I have a label for displaying the current time. My coding problem, as it were, is that I cannot figure out how to make the label display the current time, or how to get my program to play the music when the time comes around.

• Visual C# Why does 'String' not have a copy constructor?

  Is there a reason that the 'System.String' type does not have a copy constructor A 'copy constructor' is a constructor that takes its own type as a parameter. I would have expected the string type to have copy constructor as it should permit strings to easily share the internal reference to the string data. This would both improve performance and reduce memory consumption as the internal string data object is shared, and not constructed, from the existing string to the new string. Am I missing something There is no such thing as "Copy Constructor" in C# so I assume that you want a contructor like String(String another); The problem is that it is completly useless. Strings in C# (unlike m ...Show All

• Visual Studio Tools for Office Prevent outlook from closing or user from changing a item

  Hi again! Im having some troubles on outlook add-ins. Does anyone knows how to: Detect that outlook is closing and ask the user if he really wants to close outlook while the add-in is performing some action (example: sending data or receiving from a server). In this situation is there a way to prevent outlook from closing Detect if a user is changing a item. Prevent a user from changing any item while the addin is doing something.

• Visual C# Converting images to matrix form

  Hi! I am currently doing a project on Locality-Sensitive Hashing. One query I have is whether is it possible to use C# to convert an image to a unique matrix of high dimensions. Any help would be greatly appreciated. You can certainly use this declaration: int[ ] image = { x0, x1, x2, … }; but I think this could get a little tedious. A little more detail in your question would provoke a more accurate response. ...Show All

• Software Development for Windows Vista Urgent: Scheduling service in Sharepoint workflows

  Hi, Hosting a workflow in sharepoint yields in major scheduling service issue. The manual scheduler service can't be controled and thus the delay activity in turn isn't feasible. A possible walkaround was to create a task with a duedate. A windows service will run on timely basis and checks all the tasks with expiry date and updates them. In theory, updating a task will cause the workflow to trigger the OnTaskChanged method, but in practise, this wasn't the result. When this task is updated, the workflow isn't affected, whereas when manually updating the task an error occurs "event isn't received". The reason is due to the fact that the updated workflow in the windows service doesn't run the scheduler and as aresult, the workf ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. System.Reflection.Assembly

  I'm finally getting around to porting what I had written during beta 1 over to the RTM. I'm thinking about building my engine in a modular fashion so that I can issue pluggins to extend its abilities easily. The XNA documentation lists System.Reflection.Assembly as an supported object on the 360. Is this true, and how does the FromFrom, etc methods work on the 360. Obviously the file paths would not be the same as Windows. I do not have an Creators Club Membership to verify how this works on the 360, but would like to know so that I could potentially plan for such functionality (If possible). A quick search on the forums did not reveal any prior posts on this topic. Thanks. System.Reflection.Assembly.LoadFrom can take a ...Show All
