• Anuragsh_21 Dialog Box Shadow

  Is there any way to get a shadow drawn under a dialog box with no frame. Prior to Vista I used a thin frame, which gives a shadow, but under Vista the thin frame is thick and allows selection and dialog box movement, thus I now have to use no border to get a non-moveable dialog box. In XP, the default window frame size when it is "fixed single" is 1 px. it can be changed to be bigger in XP by going to Display Properties > Appearance > ...Show All

• rstuven (State Machine || Sequential Workflow) || (State Machine + Sequential WorkFlow) ??

  There has been a lot of talk about State Machines are good for human workflow and the sequential workflows are good for system workflow.  I would like to present some issues about the state machine for human workflow and get opinions. First, I agree that human workflows are good for the state machine.  First they are easy to understand because there are single state.  So “Awaiting Approval”, and ”Completed PO” are easy to und ...Show All

  How does a child activity obtain access to the Fault captured by a FaultHandler I have a code activity as a child of the FaultHandler. I simply want to spit out the message from the exception that was caught. I tried using the Parent property, expecting that to give me back a reference to the containing FaultHandler, but it was null.

• tusharp How to detect the video capture device is in use or not?

  I built a simple filter graph by adding video capture device filter and render filter to preview the webcam's video frames. It work very well. But i always get a black blank frame in the preview window if another software launch the webcam first. So i want to know beforehand the webcam is in use or not. if there is other software using the device, I think it is necessary to prompt the user to preview later. And i know the IMediaControl's GetStat ...Show All

• lester - MSFT Custom WorkflowScheduler issue - Timed workflows are being scheduled twice

  I have implemented a custom WorkflowScheduler to give me control over threading. I am running into issues with timed activities. My sample workflow has alternating code activities and delay activities. When I reload the workflow after the delay has expired, a call to my scheduler service is made to schedule the workflow with timer information. A second call is also made to schedule the workflow without timer information. This causes the ...Show All

• Dan D9182 Confusing statement in MSDN article on WWF

  In this month's MSDN magazine article on WWF by Don Box and Dharma Shukla  there is the following paragraph: " Despite the inherently asynchronous nature of the runtime/activity contract, the runtime will never make concurrent calls to a given activity. Rather, any given activity is guaranteed to have at most one method invocation executing at a given instant. This vastly simplifies the task of writing activities in languages like C# or ...Show All

  On a State Machine WF I would like to have a state where I execute a code block and move on to the next state. It seems that there are several ways of doing this. I can think of two ways: 1. Add a state. Insert an event into the state. In the event place a delay (zero delay). After the delay place a code block and finally a set state. 2. Add a state. Insert a state initialization. In the state initialization place a code block and final ...Show All
