• Tamil mannan CreateInstance failed

  Here's the situation. I have a XAML only workflow in a C# project (A). The workflow references custom activities (derived from Activity etc) that are built in a separate project (B) in the same solution. The reference is via a namespace reference in the workflow XAML. (...... xmlns:ns0 = " http://ABC/ActivityLibrary ....) Project (A) has a reference to the dll generated by Project (B). It's a direct reference - the reference is created by pointing to ProjectB.dll in a common directory. One of the types in (B) contains the following directive to map the namespace identifier to the assembly [assembly: XmlnsDefinition ( "http://ABC/ActivityLibrary" , "ABC.UI.ActivityLibrary" )] I open Visual St ...Show All

• Cobaia DirectShow 2 input filter

  I have created a Directshow filter that has 1 input, the base class is CTransformFilter. The input is MEDIASUBTYPE_RGB24. The filter does some color correction. Now I would like to add another input and make it a two input video filter for DirectShow. The idea is to use the second input for doing a composite. Both inputs should be both MEDIASUBTYPE_RGB24. Has anyone done this before Should I still be using the CTransformFilter base class Or should I use another base class or extend CTransformFilter base class to support 2 inputs. If anyone has any code samples for 2 inputs vide filter that would be great Don James I am outputting the result of the filte ...Show All

• Kamel Balquis Suggestion for Login GUI

  Just wondered whether MS could add in an option to change the background wallpaper for the login screen, even if they could only be changed to any of the wallpapers in the "wallpapers\vistas" folder, to keep with the general theme of vista...

• SomeDeveloperPerson Database for samples ?

  Hi Where can I find database for samples from netfx3.com I was looking in workflow's samples and some of them need database but it's not provided. So where it can be found Jedrzej The Rules Creation Database can be found at: C:\Windows Workflow Foundation\Examples\ExternalRuleSetToolkit\2006-03-23\ or something like here. If you have doewnloaded the sample you should find it in the downloaded root directory. The setup.cmd and the setup.sql should take care of creation of Rules Database and the tables. Thanks, Kushal. I've found it already I made stupid mistake when I was unpacking file... I had a lot of files in my current directory but I thought it'll give me another nice directory.

• unsigned int Bound Dynamic properties not retained after save - Using Vihang Dalal's Designer Rehosting

  I am using Designer Rehosting code posted by Vihang Dalal. I am also using DynamicPropertiesActivity from Ghenadie's blog. I create a workflow with DynamicPropertyActivity as one of the activities. Added 'strTest' to DynamicProperties collection. In order to be able to use this attribute in the rest of the workflow to bing to other activities, I believe I have to bind 'strTest' to a new member. So created a new Property member say dynProp_strTest. I can now use dynProp_strTest to bind to other activities. So far so good. The issue comes up when I try to save this workflow and then reopen it again in Designer. I can no longer see the new member 'dynProp_strTest' that I created. I understand it is getting lost during Save, but do not exactly ...Show All

• Mauricio Castillo E Where did the support for the Summary property page go?

  We have developed an application that uses compound documents and the summary info property set. In Windows 2000 and XP, there is a "Summary" tab for our files when you select Properties in Explorer. This is no longer available in Vista. Is this by design Can we reenable it somehow We are testing on Vista RC2. It used to work in Vista Beta 1 (or maybe it was Beta 2). In that version you also got information in the Details pane in the Explorer. /Thomas It's still there; it just got a new name. It now goes by the name "Details". Well. Thank you anyway. It seems like nobody cares about this. We use the OLE Property Store just becaus ...Show All

• markovuksanovic 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

• taumuon DirectShow within Direct3D render loop

  I am developing a 2D/3D interface using Direct3D. I am trying to also include a video window within the interface to display live TV from a tuner card. I am using VMR9. The problem I have is that the video is flickering, seemingly caused by the drawing loop. After I call D3D Present(), I have to tell the VMR9 window to repaint itself using RepaintVideo(), otherwise the video does not show at all. I am very new to DirectShow and any help would be greatly appreciated. Thanks. As stated in the title I am using Direct3D. Could you please let me know what the clipping function for Direct3D is and where to call it. Do I call it on initialization of Direct3D, between BeginScene() and EndScene(), or after ...Show All

• Chuck Clifford Vista Look and Feel on Windows XP

  Windows Media Player has the Vista look and feel with its close buttons, maximize buttons, and minimize buttons etc. etc. is it possible to develop an application using .NET and Visual Studio with any 3rd party addons or microsoft addons that would allow us to have a vista look and feel on Windows XP (while using the program on Windows XP) please dont "bump" threads. I think this is to do with the default Windows themes. There may well be some 3rd party apps that can have this look and feel but in Windows XP the only default one to apply would be the XP styles using the EnableVisualStyles() command in the Application class I believe. XP doesnt have the Vista theme as you may know, since Vista is now, XP was 2002. The ...Show All

• BeckyB Unable to call "CoInitializeSecurity"

  Hi Everyone. I'm in trouble about DCOM server & client system in Vista. When the Client try to call a procedure in a remote DCOM server, CoInitializeSecurity(client side) is failed by "RPC_E_TOO_LATE". By MSDN document it occurs when CoInitializeSecurity() has been already called. But in this case it had never been called in a same process. I have this problem only in Vista OS. It worked correctly in XP and 2003ServerR2. If anybody have a good suggestion, please tell me. Kohei.

• Pradeep Gupta Business entity objects as properties in workflows

  Hi, I recently began investigating WWF. I noticed, in the samples, there are always just individual string fields given as properties to a starting workflow (e.g. FirstName, LastName etc.). In real-world business scenarios, it would be better to hand over complete "business entity objects" containing all the fields. Is this advisable Or will I have some problems with this approach, e.g. when persisting a workflow and re-loading it later, I could imagine having versioning problems in case the layout of the business object would have changed. Would it perhaps be better to just hand over the primary key of the business object and load it from database if it's properties are needed I would be very grateful for any toughts ...Show All
