• Kira_26 Microsoft Cautions Developers About Visual Studio/Vista Conflicts ?

  http://ddj.com/dept/windows/193100342;jsessionid=QVOCPBYPBOZZGQSNDLOSKH0CJUNN2JVN It means we cannot use Visual Studio 6.0 Is this True it may well be. VS6 is already old and outdated...best to move to bigger and better things. You can use the FREE Express editions of .NET, with some limitation of course but not time constraints. About time you moved on up ;-) As if it would be that easy to migrate to new IDEs and OSs... ...Show All

• KitGreen Drawing pixel based animations

  I have read the QuickStart but I haven`t seen any option to create an bitmap in memory and display it to perform old school pixel based effects. Is this possible I think that in WPF this is done via the BitmapSource class. Is there something similar for WPF/E Thanks! Joe, thanks for the reply. I hope you include this in a future release because IMHO doing pixel based effects is very useful in a lot of scenarios and especially for web based games. The December CTP does not support this feature. We will consider this for a future CTP or release. Joe ...Show All

• RobertWG SampleGrabber fail after unlocking from lock screen in XP

  Hey guys, I'm having a problem whit my direct x graph; I'm performing acquisition with a SampleGrabber (and also using a callback to retreive my samples).

• Giftednewt Calling CreateProcessAsUser() from service

• Jérémie Faucher-Goulet Consuming custom activities at runtime using the WorkflowDesignerControl

  I am using the WorkflowDesignerControl (WDC) to create an application to provide simple enduser workflow authoring. I envision the application working something like nUint, where a user would point to a set of assemblies containing custom activities they wish to consume.  The application would then... 1) Load the assembly 2) Add any types derived from Activity as custom activities in the WDC Toolbox... The problem I run into is that it seems difficult to add a custom activity at runtime.  The only way I could really do it was by tinkering with the SelfHostToolboxItem class and forcing it to specifically load my assemblies. Howver, even when I do this, if I use the custom item on the design surface the WorkflowView ...Show All

• MatrixResolver Test Case 22 and Shortcut table

  Test Case 22 asks to compare tables from schema.msi with application msi. Problem is the Schema.Msi file used is from Windows Server 2003 R2 Platform SDK, and does not contain Vista specifics columns. In "Shortcuts" table, "DisplayResourceDLL", "DisplayResourceId", "DescriptionResourceDLL" and "DescriptionResourceId" are missing from the schema.msi table. Test case 22 should be updated to allow this 4 extra columns. Julian, You are correct, a discrepancy in these columns does exist. The test cases are being updated to require that the Windows Vista SDK be used. You can download the SDK here. http://www.microsoft.com/downloads/details.aspx Famil ...Show All

• Alex_UTL ASP.NET and WWF

  Hi, I need to build anything like this :-) Scenario: 1) The user clicks in a button and start the workflow. 2) The workflow executes an activity and stop waiting for a action user. 3) In any moment the user access a asp.net page and list all workflows pendent and approve and cancel the workflow. 4) The stoped workflow is notified and resume the flow.

• Abe1816 SHFileOperation and 8.3 filenames

  Hi, I'm not a programmer or anything, so I'm quite new to the API and things. I have a complicated reason for needing to use 8.3 filename spec to remove some directories. My function has worked perfectly on 2000/XP, but it returns "2" on Vista. (Vista Enterprise 6.0.6000 N/A Build 6000, x64-based PC ) After looking around, it seems that winerror.h resolves that as "ERROR_FILE_NOT_FOUND". The file clearly exists, and a "dir /x" will give the 8.3 name that I'm using. Also, I believe DeleteFile works with 8.3 names, but not SHFileOperation. Can someone please confirm this for me I hope it's not a silly mistake on my part. (Note: I'm not natively coding these API functions, I'm using a plugin that makes the API c ...Show All

• Aloepages Workflow + Offline + SmartClient

  Hello guys, I'm in the middle of an architecturing project, and basically we are talking about 4 or 5 workflows with some complexity, and integration with 3rd party ERPs. The cath is this: all users are working in different offices, ocassionally connected, so the solution MUST be SmartClient (web is not an option). When they are off the network , they should be able to start a workflow, or to approve some pending, and then when back online, synchronization should occur. The creator can be in one office, it posts to the server for some ERP validation, and then it goes to step 2,and that is another user from another location, and so on. Basically the question is: is it possible with WWF Or it would mean more work than using somethin ...Show All
