• Sharma Problem with custom CallExternalMethodActivity

  I have successfully implement a local service allowing me to pass parameers into the workflow. Now I want the workflow to return data.

• AamirHabib OTP: Vista Beta 2 5384 x64: black - blank screen problem

  Hi everyone. I have a problem with a new installation of Windows Vista beta 2 build 5384 x64. After the installation the PC booted in normal mode, but I see only a blank screen without any cursor or information. I am able to boot into safe mode (I managed to install the nVidia 88.61 from there) and log on, but when I reboot into normal mode I can't see anything appearing on screen. I also tried to manually update the driver from the Device Manager in safe mode and nothing. I tried even to boot in "Allow unsafe drivers to load" but no gain. Here are my specs: Athlon X2 4800+ 2 GB RAM MSI K8N Diamond 2 GeForce 7800 GTX (SLi config) 2 Seagate Barracuda (300 GB each) Thanks!! These forums are for v ...Show All

• JLutz Writing to Global Shared memory from an Application in Vista.

  Hi all, Global shared memory is created by a service which is used by my user mode application to communicate with the service through global mutexes and events. This as of now works well in Vista RC1. 1) Are there any restrictions that an application should not write to global shared memory already created by service This application does not has any elevated privileges. 2) Can application created global named objects like event and mutex Again the application is running under a standard user privilege and not as admin. 3) Can a 32bit application on a 64bit machine get interfaces to a 64bit Local server COM object Is there any special processing required in the 32bit app or in the 64bit local server COM object.

• Richard Meijer starting application from setup - not as administrator

  Hello all: When my application is run for the very first time at the end of the installation process, it is running as administrator, because the setup itself was automatically detected and elevated by Vista. Is there any option to run it from setup at usual (medium) privilege level I have tried manifest with requestedExecutionLevel of asInvoker - to no avail. TIA OTNS I think of it this way - if you had an .msi installer, would you see the shield I'm kind of curious about this install-time service approach.

• Majd Yafi Rehydrating instances persisted in previous execution

  Hello, My project is similar to expense reporting. Someone sends an order, it is stored into a list in memory, and then the workflow waits for an event (Reviewed). I've just added the default SQL persistence service and it works fine. I've subscrived to the idled, unloaded, persisted and loaded events and I see that once it receives the order and it starts waiting for the reviewed event, the instance is unloaded, and once the event arrives it is rehydrated and completed successfully. What I want to do now is: say I start the host, and I receive 2 orders. One is reviewed and accepted, so its removed from the persistence database. The other isnt, so its still kept inside the DB. Then the host closes. Later, the host is re-opened a ...Show All

  Hello, I have been learning Windows WF recently. But I've got a big block at the beginning. I want to develop an overtime management system. And it’s a long flow system,I think.
