• Windows Live Developer Forums Image Overlays

  I working on a project and want to overlay an image on my VE map. Ideally I'd like to just insert the image onto the map as a layer, and implement a callback or event to re-render the image when the map changes, however this doesn't seem to be supported like it is in Google maps. My image is generated at runtime based on the size in pixels of the entire map window, so I cannot statically create a set of perfectly sized tiles. When I tried the tile solution example as shown in the Interactive as "Use custom tile layers", my image was tiled across the entire screen many times (because I had just pointed the TileSource to my Image generator URL without the use of any of the given parameters such as %4. I didn't even see doc ...Show All

• Software Development for Windows Vista Unexpected termination of state machine workflow

  I have recently encountered an issue with my statemachine workflow, where the workflow is terminating. I have enabled tracing for the workflow. My workflow is signed. My workflow is exposed via web services. The interface and messages used by the WsInputActivity is located in another assembly, which is also signed with the same key. Here is the output of the error information. Does anyone have any idea what might be going wrong Obviously something is throwing an argument null exception, but the where and the why is very puzzling to me. I havent been able to find any information on the objects in this set of exception details: Description: An unhandled exception occurred during the execution of the current web request.

• Visual C++ Refreshing Visual Studio C++ Intellisense

  I often find that C++ intellisense in Visual Studio 2005 takes quite a while to update, especially when I've copied and pasted a lot of code. It seems that you can force it to update, by either: 1) Closing the solution, deleting the .ncb, and opening the solution 2) Toggling between 'Debug' and 'Release' builds (I guess the change in compiler options causes the intellisense to detect a change). I've spent ages searching for a shortcut I can press which will just force it to update without doing either of these, but haven't come up with anything yet. Does anyone know if there is such a shortcut Thanks, Matt IntelliSense updates all the time in the background. The two actions you mentioned do ...Show All
