• murratore SMS 2003 Admin Console Remote Control on Vista 5308?

  I have the SMS 2003 Admin Console (with Service Pack 2 applied) running on Vista build 5308, but I can not remote control a client.  I can connect to the site database just fine, see my collections, use the Resource Explorer and even make the initial Remote Tools connection OK via Port 2701.  But when I try to actually initiate the remote control, I get an error message that states "Cannot establish a security context with the client."  If I try again it prompts me for security credentials but nothing will work.  I have my firewall disabled while on the domain, so that isn't an issue.  LOL, I know I'm not supposed to be running Vista in production on my primary workstation, but it's running great with this being my ...Show All

• pablo in the oakgrove GEM Plus USB Card readers

  Does anyone know if there is a newer version of the Gemplus USB card reader drivers It doesn't appear to work at the moment with Vista. That said, I haven't been able to uninstall the old drivers to even put new ones on yet.. Vista just doens't uninstall it when you try. Yes, that's a fair one. I'll contact Gemplus and let them know about the issue, and I do accept it's not a Vista issue. Thankyou for your reply. Glyn Harper. Hello Oliver. I'm unable to install any new drivers, as it won't let me remove the old one. If I got into Control panel, then Programs and features, I do see the program installed, which is Gemsafe libraries 4.2.0 sp1 You clic ...Show All

• hannesaj How to get a shared Data context inside a workflow instance accessable from all child activities?

  Hi, The idea is to have a data context accessable to all activity instances living inside a running workflow instance. This data context class instance is prepared before the workflow is started and should be retrieved back ( to the caller) when the workflow has completed or terminated ( to gain informations about state/error conditions). 1. Is there a build-in way to do so It seems like ActivityExecutionContext which is given for each execute does not solve this issue. Here's my happy guess solution to solve this issue. I've created a custom SequentialWorkflowActivity which will serve as base class for all my workflow definitions called SequentialWorkflowActivityBase . public partial class SequentialWorkflowActivityBase : Sequ ...Show All

• JFoushee Visual Studio 2003 hangs on Vista Build 5472

  If I try to use the "Find in Files" feature of VS 2003, it just hangs VS and you can only kill the process. This happens when you select search in Entire Solution or Current Project. Note: I have launched VS to run using Administrator. This did not happen on Vista Builds 5342 or 5308. Is there any workaround Fantastic... Thanks! Thank you very much! I had to install XP just to use VS 2003. Now that this sorts out the find-in-files problem, it's working just fine for me now. I'm using a Centrino/Pentium M (IBM T-40 notebook), and the bug still occurs ... any other differences between the two PCs ...Show All

• jlchx SetupIterateCabinet failing from Custom Action .dll

  I use Visual Studio 2005 to deploy my application. I have a Custom Action .dll that's called during the Install phase. (The entry point is the standard Install( MSIHANDLE ).) I'm installing a .CAB file and am calling SetupIterateCabinet() from this Custom Action .dll and it is returning ERROR_ACCESS_DENIED. Appears as though Custom Action .dll's are not run with the UAC elevated privileges of the .msi file. I tried adding a .manifest to give the .dll elevated privileges, but then Windows XP barks that there is an unrecognized token. I need this .msi file to run under both Windows XP, Windows 2000, and Windows Vista. Because this is a Custom Action .dll there is no way I can wrap the function in a COM object and call it with ...Show All

• Steve Whitley PowerShell - dir /o:d /b

  I am trying to duplicate the functionality of dir /o:d /b in PowerShell. This is what I have so far (and have found by searching the Web): dir | where-object -FilterScript {$_.Mode -like "d*"} | ft Name -H This works OK, EXCEPT that it includes a blank line at the top of the list. That is, if I redirect this command to a file, the first line will be blank. How do I get rid of the blank line My ultimate goal is to pipe the output to my own cmdLet, but it won't bind because the first "row" of the output is null (and I am guessing that this is because of the first blank line). Also, is there a more appropriate place for questions on programming in PowerShell Thanks! Thanks, Richard. I found my ans ...Show All

• jmsigler2 In July CTP, using StateMachineWorkflowInstance to obtain CurrentState freezes workflows in that State

  Dear all, I have a working StateMachineWorkflow hosted under asp.net 2.0. I have written a simple routine (shown below) to interrogate the current state of a workflowinstance: public string WfCurrentStateDescription(string WorkflowInstanceId) { // Get the workflowRuntime which was started in global.asax WorkflowRuntime wfRuntime = (WorkflowRuntime)Application[WorkflowRuntimeKey]; StateMachineWorkflowInstance wfInst = new StateMachineWorkflowInstance(wfRuntime, new Guid(WorkflowInstanceId)); return wfInst.CurrentState.Description; } I find that, once I have called this on a workflowinstance, that instance gets "stuck" in the current state and never transitions to the next state, even though code appears to get c ...Show All

• ccote HandleExternalEvent activity in Parallel

  I have a few activities in parallel that listen for the same event. With the event arguments I will see which one of the parallel activities to execute. It seems though that the event is only fired in the first activity and not in all the activities waiting for this event to fire. You have to fire the event twice from the host to make both HandleExternalEvents fire Well - you could query the WorkflowInstance.GetWorkflowQueueData to see how many activities are listening for a particular event Yes, but in the problem statement, he indicated that he was going to choose which branch of the parallel to execute based on the event arguments; leading me to believe he does not want to run both branc ...Show All

• HKT Exception on raising an event
