• Smart Device Development Prevent standby/keep app running in standby?

  Hi All I'm currently writing my diploma thesis and as a part thereof i am writing a WM based application to constantly log some data (various sensor input via Serial, picture capturing, audio recording and GPS via Bluetooth) which will later on be used for some data mining/context awareness stuff. It is absolutely crucial that i have a constant stream of incoming data that is not interrupted by e.g. standby, be it system or user initiated... And that is exactly where i am stuck now... :-( Does anyone know how i can prevent my wm 2005 PPC device from going into standby, even if the user clicks on power off button However, if this is possible, will the keys and the touchscreen still be locked (not a must, but would be nice) (Btw.We ...Show All

• Software Development for Windows Vista Invoke Workflow

  In ParentWorkflow i am using InvokeWorkflowActivity to invoke another Workflow(child) Every thing goes fine but control is returning to Host two times - one from Parent and another from child. my requirement is Child should inform the parent and parent should inform host. i have used handleExternalEvent in ParentWorkflow to handle event of child .

• Visual Basic Difference between WithEvents (Handles) vs Add Handler

  I am learning VB 2005 and have a question. Events can be created either using With Events or using Add handler. So far VS IDE put all code related to with events and handles for me. Can any one explain add handler clause to me. What is the difference events created using with events and handles vs add handler Only thing I found on MSDN is that Add handler can be used during runtime instead of design time. Any one would be able to clarify You can't declare a local variable using "WithEvents". So if you want to progamatically add a TextBox, lets say, to your form you would have to declare the TextBox at the class level to use the WithEvents keyword. If however you want to declare the Te ...Show All

• SQL Server Last image of Historical Data

  Hello, I have a slowly changing dimension Sales Person of type 2, where I am keeping history of the sales person Unit, Region, and Sales Channel which are attributed on the Sales Person dimension. The client is requesting to be able to report on the Sales Person last image, for example if the last image Region of this sales person is Region X, then all the portfolio of this Sales Person should now be linked to Region X irrespective of what it was historically. At the same time, we should be able to report on the production done by region as it occured historically. To my kowledge, my design would allow to report on production historically but not the last image. I read about an article that suggested to create additional attribute ...Show All
