• Software Development for Windows Vista Delay Activity in the StateMachineWorkflow

  How dow we introduce the delay activity in the StateMachineWorkflow. when I do that along with EventDrivenActivity it gives the error saying only one can exist.

After the first event/delay in an event driven in the state, you cannot have another blocking activity (delay/event) during that set of actions. If you ...Show All

At this point I have my variable declared at the beginning and globally availabe and I have the button click set up to prompt for a new input.  When the input is entered my lable change takes place and the new ...Show All

• Visual C# Wave Recorder - problems with a splitted/joined audio record

  I've written a small application to record data from an audio device to a wave file ( based on this article ). A further function is saving/splitting a recording in several files. If I play the files later back, it should sound as one continous recording, but it doesn't. There are short breaks/clicks in between. It seems that the recording function doesn't capture the input properly. You can find my application/VS project here (22 KB): download Can anyone see what's wrong Any help appreciated!

• SQL Server Database Diagrams: FOREIGN KEY constraint "fell off"; can't drop/recreate it...

  Hello, I have two tables Person & Location where Location has a primary key LocationId and Person has a foreign key LocationId . Sometime ago I used the Database Diagrams visual tool of SQL Server Management Studio Express to create the foreign key relationship between the two tables - i.e. "visually" (drawing a line between the PK & FK LocationId elements of both tables). Time has passed and I recently noticed that, upon retrieving my saved diagram, the foreign key relationship had "fallen off" (i.e. the many-to-one line was no longer showing in the diagram). After recreating the relationship (redrawing the lin ...Show All
