• Software Development for Windows Vista SQLPersistence in Custom Activity

  I am creating custom activities on the fly and including these activities to the workflow designer toolbox. On completion of every activity on my workflow, I want to persist my workflow. What will be best approach for implementing this I though of adding persistence code in the Execute method of my custom activities. At the time of creating the custom activity, I won't have a workflow instance running and so this is not possible. Is there any way i can raise an event from the Execute method of custom activity I need a trigger to handle the persistence on my host application. Any help will be appreciated. Thanks ...Show All

• Visual Studio Express Editions Another way than WH_CALLWNDPROC

  If I'm using a VC++ DLL to create a tray icon for an external application, not my own nor connected to my DLL. Is there any other way to detect mouse clicks on that tray icon other than a global hook for WH_CALLWNDPROC I've read that a global WH_CALLWNDPROC hook can be a serious drain on system resources so if at all possible I'd prefer not to use it. If it's the only way to catch the messages I want under these circumstances then I'll do it, but is there another way W For win32 dev issues, please use the newsgroups at http://msdn.microsoft.com/newsgroups/topic.aspx url=/MSDN-FILES/028/201/015/topic.xml ...Show All

• .NET Development making a data source control

  Ok, I'm making a control that extends DataSourceControl, and it seems like there is many ways to go about things, and I'm not sure how they were intended to be used. It dosen't appear that I need to extend DataSourceControl at all, I can just make a bunch of functions that return DataSet objects and then create a bunch of ObjectDataSource objects that call them. This seems like a better solution, what additional functionality do you gain via a DataSourceControl ...Show All

• Visual Basic RAMdisk

  Can you create a RAMdisk in VB2005 (or VB6) code I write a file to the hard disk, and then read it back for viewing and printing. Sometimes I need a faster turn-around time. Loading or Reading from RAM would avoid introducing delays to wait for the disk file to be ready.
