• Jean-Pierre Fouche overload methods in WF

  Hi all, i would like to know how can methods(activity) be overloaded in WF. For example i have a if-else activity, a sendMail() method. If the ToName is XXX then doSomthing() and then sendMail(XXX), else if ToName is YYY then doSomthing() and then sendMail(YYY). How can the parameter be handed over Should i use a queue for the parameter (or Dependence Property) But how can i choose at runtime the right parameter Thanks Hi Emy -     The solution I proposed doesn't suit your actual scenario. You should define Directory dependency property for the moveFile activity and To, From dependency properties for the sendMail activity. Then in the workflow you could add the two activities [mo ...Show All

• qrli 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 Thanks, A.J and Robert, you're life savers! This hang in Find In Files was driving me crazy. I do those finds a lot and VS2003 would become unresponsive after doing so. Disabling the Visual Themes did the trick! Seems bizarre but it worked. I've had no other significant problems running Visual Studio .NET 2003 on Vista. [Of course, you do have to run it as an administrator.] Ji ...Show All

• ChaosUK EventTrigger RoutedEvent Support

  Currently all RoutedEvents are interpreted as "Canvas.Load". Is there any plan in the v1.0 timeframe to support other RoutedEvents in the XAML I know we can get around this by using BeginTime and starting the events with JScript, but I am looking for the official position on this feature set by release. While we plan on improving the way animations are specified in WPF/E (e.g., remove the need for the very large BeginTime workaround), there are no concrete plans to support other RoutedEvents in the first half of 2007. The recommended way to start animations is to call storyboard.Begin() in script. Ed Maia WPF/E PM ...Show All

• Keith Hill Hybrid Workflow?

  Hi guys, I have a strange workflow to implement with WF. First, there're 4 states, and 4 approvers of course for each state. The strange thing is that when the user initiates the workflow, he/she must specify the user for each of the first two states, the others are fixed. So it would be: First State Approver defined by user (creator) 2nd State Approver defined by user (creator) 3rd State Fixed 4th State Fixed Do you have any idea of how could this apparently simple workflow could be implemented thanks in advance! Victor Thanks Serge, a great idea indeed. I didn't realize I could send the future approvers as parameters. I'll work on it. thanks again, Victor Vict ...Show All

• antoan Using wimgapi.dll with VB6 - WimApplyImage causes VB6 IDE to freeze?

  I'm writing some code to use the wim imaging api wimgapi.dll with VB6. The code works 100% on capture, with the callback function correctly getting progress information and updating my form with progress bar etc. This works fine when run from within the IDE or from the compiled .exe. The apply image code is a problem though - the WimApplyImage code locks up the IDE part way through. When run from the compiled exe, I get no progress messages to the callback - I do get all the process messages though, and it actually works in that it correctly applies the image, but it stops updating my form until it exits the WIMApplyImage function. Anyone have any ideas I've tried registering the callback both immediately before the WimApplyIma ...Show All

• Tom T. How to create .ISO image file

  I want to create an .ISO file instead of burning an image to disc.  These are the steps I'm assuming I should take: CoCreateInstance to obtain an IFileSystemImage object Add files/folders to the image using IFsiDirectoryItem and IFsiFileItem Call IFileSystemImage::CreateResultImage to obtain an IFileSystemImageResult object Call IFileSystemImageResult::get_ImageStream to obtain an IStream object Call ::SHCreateStreamOnFile to create the new .ISO file, and obtain a second IStream object Use IStream::CopyTo to copy data from the stream obtained in step 4 to the stream obtained in step 5 Are there any problems with these steps   Any potential pitfalls I should be aware of   The Win32 docum ...Show All

• MHR Web Application templates for VS Express?

  Hi, just wondering if there are any templates available for VS Express On the homepage of one of the downloads specified in the Release Notes it is stated that "To fully enable Web Application Projects in Visual Studio 2005, you will need to first install Microsoft Visual Studio 2005 – Update to Support Web Application Projects , then this add-in. Visual Studio 2005 Web Application Projects are not supported in Visual Web Developer Express Edition." Is there perhaps a way to register the template by hand The installer for the VS template states that it "ended prematurely because of an error", probably because of the the missing "Web Application Project" add-in.

• GOH Omnipuff Application fails to start under Vista: "A referral was returned from the server." Manifest problem?

  I'm working on migrating a driver management application (written in Visual C++) to Vista. It requires access to HKLM, so it needs to run with admin access permissions. For testing purposes, we've been modifying secpol.msc to run it in admin approved mode, but obviously, that's not the right thing to do. The right thing to do, from what I can tell, is to add a <trustInfo> tag to the application manifest (which is embedded in the .exe as a resource). I did that, but now the application fails to start under Vista at all, with the error message "A referral was returned from the server." It still works fine under XP. The manifest is pasted below. Does anything look obviously incorrect If not, is there anything that could interact badly w ...Show All

• m.eisenstein IMediaDet interface - access violations

  Hi all, I've written a DirectShow app to sample frames from various video formats and capture the frames as bitmaps. It works but I'm getting access violations when I use the IMediaDet interface. I create it using: CComQIPtr<IMediaDet> pMediaDet; HRESULT hr = ::CoCreateInstance(CLSID_MediaDet, NULL, CLSCTX_INPROC_SERVER, IID_IMediaDet, ( void **)&pMediaDet); When I create my sample grabber I use IID_ISampleGrabber and not IID_BaseFilter (which I know can cause access violations). The IMediaDet functions: put_Filename, get_OutputStreams, put_CurrentStream and get_StreamType are fine. However the functions get_FrameRate and get_StreamLength have access violations. I've searched the forum and found that someone else had ...Show All

• Richard_Wolf Hardware Profiles & Windows Vista

  Hi, My question is about hardware profiles. In Vista the boot environment has drastically changed, and a hardware profile selection dialog (text mode screen during startup) seems to have vanished. I'd appreciate any information about how to a) reactivate the hardware profile menu or b) query user input similar to that menu during system boot. Description of my App (for you to understand what I'd like to achieve): My App's heart is a boot start driver which runs far before explorer or normal services. No GUI is available there. The user must be able to choose wether or not to activate the driver's main functionality. That has been implemented by creating and managing an additional hardware profile. It doesn't work that way for V ...Show All

• etcheverrjc get PTS from MPEG2 live stream / demultiplexer

• GROTH transactions and ExternalDataExchangeService

  I have a state machine workflow that represents my process. At a pre defined time, a bunch of instances get kicked off. Then individual users interact with specific instances to move them through their states. Finally, at another pre defined time, I need to complete all the instances, followed by running a stored proc. To complete the instances I can just iterate through all the active ones and raise my ThingyCompleted event in my ExternalDataExchangeService. The trick is that I want all the event raising and the execution of a single stored proc to all happen in the same transaction. Since the stored proc is basically a rollup and needs to happen after all my workflow instances complete, it has to be run from the host (as opposed to ...Show All
