• Windows Forms TreeView fails to display icons, why?

  **also posted to VSTO form...no replies ** My VSTO Outlook add-in shows a form with a TreeView control. The tree works properly, showing the data I expect it to, but not the icon images. When I add a default root node in VS Designer and assign it an image from my ImageList, it appears correctly in the designer. When I run the add-in, the default node appears, but without icon. There was a related thread MSDN Forums Windows Forms Windows Forms General Icons not showing up on Treview on VSTO beta, but no real answer posted. Anyone have any ideas The debugger shows that the TreeView object does have the ImageList, and that the ImageList has the right number of images, and that the nodes have ImageIndex values in the prop ...Show All

• Software Development for Windows Vista Freeformdesigner --> saving to XOML

  Hi! I have implemented a workflow surface who is using the freeformDesigner. I can now resize and move the activities free around the workflow surface. I can also draw arrows between the activites in any direction I want. I have used much of the flowchart example code. Here is my BIG challenge for you: When I save the workflow and re-open it it doesn't appear like it was before I saved it. The activity-boxes' position and size is correct (I have implemented this). The problem is that the arrows between the activity-boxes is gone. How can I save the arrows' position into the XOML-file I don't even know where to look for this properties... Thanks a lot!

• .NET Development Port Binding and Intercepts

  I have attempted asking this question all over, and none of the responses I’ve gotten have proven to be helpful. I’ve created a listener and client in c# along with its related DLL. I’ve gotten the port to bind and the listener works fine with the client. My question is this – Logically, if you bind a port, you should be able, under some sort of event triggered, to intercept a soap request before it is dispatched to it’s relative service call, and after it has been dispatched to that service call , i.e. Before the request is carried out and after it has been carried out, but before the response is sent. I would expect some sort of OnBeforeDispatch event and OnAfterDispatch event, or something of that nature. My reason fo ...Show All

• Windows Forms EventHandlers for dynamically created controls.

    I am trying to subscribe to the click event raised by the dynamically created LinkButtons in MyCustomTable class. I want to handle these events in the code behind of my webform. In my webform.aspx.cs I instantiate this custom control and pass it in a populated sqldatareader and it returns a table which I then add to the  to a placeholder control on my page.
