• Alex Krapivin Webservice Workflow with Dynamic SetState Activity

  I am writing a webservice workflow using Visual Studio 2005. I am trying to add in a Hold State in my workflow so that users can temporarily hold an approval process or something. I can use recursive composition to create an event so that the Hold State can be reached from any other state. The problem is --- how do I then return to the previous state before the Hold State I have tried to set the TargetStateName property within my workflow class (inherited from StateMachineWorkflowActivity) in a CodeActivity but I get a InvalidOperationException. It seems that I can't set the state within StateMachineWorkflowActivity while running. Thanks for any help. Thanks to everyone who answered my cry f ...Show All

• mike6271 Pseudo Code anyone?

  Ok Experts, I am looking for nothing more than pseudo code at this point - I've done little more than dabble around with the UI, created a simple activity, done some limited persistence etc.. Here's what I would like to do: Create a new WF instance Persist, and place the Instance GUID in a table, along with other attributes Present this list and allow selection Open the WF Instance again, and munge around with it - add properties etc.. Continue along the WF route and evaluate rules as necessary Persist again, etc.... Essentially I am not seeing the easy way to open a WF instance, work on something related to it, then update some properties and have it reume it's path ... Anyone care to point me in the right ...Show All

• parm12 Black Screen / Freeze after first reboot

  I have spent many hours the past week trying (unsucessfully) to install Windows Vista. I have downloaded and installed all the most recent drivers and BIOS updates for all of my hardware. I have run the Vista Upgrade Advisor and it says that my system should be good to go and that there are no serious issues. The only item on the "Task List" is to download Vista drivers for a wireless networking adapter I have in the system to be installed after. I have tried to do an upgrade from Windows XP and a Full Install of Vista with the same results. I start the install and everything goes smoothly (installer unpacking files and getting ready for installation) until right after the first reboot. The system restarts and tries to boot in ...Show All

• Guwapo Deploy/Debug CE app from Vista

• CJKeatley properties - file dialog

  Hi! I am making a custom activity, and I have a file property. I want a user to select a file from a file-dialog. How is this possible thanks You can do this with a custom UITypeEditor. Here's a quick sample I whipped up from your idea: http://www.winterdom.com/weblog/2006/08/23/ACustomUITypeEditorForActivityProperties.aspx Tom Lake wrote: Nice sample. The only comment I would make is there should not be any issues with having the custom UITypeEditor in the same assembly as the activity using it. I just did it using the July CTP build without any issues. Hi Tom, I'd agree there shouldn't be, but for some weird issue, that's what happened to me. FWIW, here's what I tried: - ...Show All

• ParkerJ21 How to obtain IDiscRecorder2Ex interface?

  I'm using code such as the following to obtain an IDiscRecorder2 interface: IDiscRecorder2* pIDiscRecorder2; CoCreateInstance(CLSID_MsftDiscRecorder2, NULL, CLSCTX_LOCAL_SERVER, IID_IDiscRecorder2, (void**)&pIDiscRecorder2); Presumably, to obtain an IDiscRecorder2Ex interface, I would substitute CLSID_MsftDiscRecorder2Ex and IID_IDiscRecorder2Ex. This does not compile, as CLSID_MsftDiscRecorder2Ex is undefined (using SDK for July TCP). I have been able to obtain an IDiscRecorder2Ex interface pointer via QueryInterface off the pIDiscRecorder2 above. Is this an implementation artifact, or is this the intended procedure Also, what is the recommended context to create IMAPI2 objects Both CLS ...Show All

• Mike Martin24365 Microsoft Activesync will not recognize Office 2007 Beta

  I have currently upgraded my office 2003 to Office 2007 Beta and my activesync will no longer recognize that Office is installed and will, therefore, not sync my Outlook data. Has anyone else had this issue Any thoughts on resolutions to this I am using HP 6325 (Phone/PDA combo) with Microsoft Pocket PC Version 4.20.0 (Build 14350) I have O2 Exec and was worried that upgrading to Office 2007 might be a mistake. Luckily it all seems to be working smoothly. Word 2007 has a compatibility mode automatically switched on. Seems no problem for transferring old .doc texts. On a few quick first tests Outlook 2007 synchs fine with the new Activesynch 4.2.0 Beta. I also use Pocket Informant and on first loo ...Show All

• skt1974 Pattern for email approval?

  With a workflow hosted by a desktop application, we want to add an email-based approval to a workflow. It is clear how to send an email as part of a workflow, but what do you recommend for waiting for approval-via email Because the workflow is hosted by a desktop application, the workflow runtime might not be running when the approval email is returned. Michael your service (the workflow host) polls your mail server (if it's exchange your can use CDO or extendedMapi I think; maybe is there a class in .Net framework 2.0 for this) and sends an event to your workflow which is waiting for it. A workflow hosted in a windows service... When it is implemented in a windows service, how would it wait for an email Mi ...Show All

• AnonymousI Visual Studio 6.0 SP5 setup on Vista Beta 2 (5384)?

  Does anyone know how to get around the MDAC check in the Service Pack 5 setup of Visual Studio 6.0 For some reason it doesn't detect MDAC 2.5 or higher which it requires (even though Vista obviously has a later version - 6.0) and the setup will not continue from that point. I've tried every registry key I could think of to trick it into thinking MDAC is installed. Thanks Ted. Can you be more exact as I have run into a brick wall when trying to install vb6....Are you sure these are the correct registry changes So I know there was the whole 'copy your files over from XP' but i wasn't satisfied with that, so I did some digging, and figured out ... it checks for mdac which makes it fail, ...Show All

  In XPS if I am printing to a legacy device I understand that all the XPS elements get translated to corresponding GDI functions. What does the <Glyphs> element get translated to DrawText No. DrawText is not a GDI32 function. It's from USER32.DLL, for drawing simple text (paragraph) on user interface. Glyphs element will be mapped to GDI ExtTextOut function normally. If the conversion is not possible, it can be translated to FillPath with the glyph outline. Feng Yuan ...Show All

• Jimbo44 Not getting drop down from design time validation error icon in rehosted designer

  I am not getting the drop down from the validation error icon in a rehosted designer. I have set WorkflowTheme .CurrentTheme.AmbientTheme.ShowConfigErrors = true ; in the WorkflowDesignerControl() constructor, so I get the icon but not the error message etc. Is there another step Yes - first you need to provide a MenuCommandService. Then you need some special handling code in the ShowContextMenu override - here is an example: public override void ShowContextMenu( CommandID menuID, int x, int y) { ICollection coll = this .GetCommandList(menuID.Guid); if (menuID == WorkflowMenuCommands .DesignerActionsMenu) { MenuCommand last = GetLast(coll); //Needed because of code ...Show All
