• Matt DC NumericUpDown control doesn't look right on Vista with VisualStyles enabled

  Hi, This question was originally posted on dotnet.framework.windowsforms, but MSDN team seems to fail on their 'reply within 2 working days' claim. Anyway, the question was: The UpDown buttons of the NumericUpDown control don't look right on Vista with VisualStyles enabled and with certain combinations of DPI and screen resolution settings. Specifically, with 96 DPI and 1680x1050 resolution the UpDown buttons are shifted and clipped. The same settings work fine on Windows XP. Obviously, when VisualStyles are disabled the control looks right, but it is kind of important for our applications' UI to have the same L&F both on Vista and XP. Can I (or Microsoft:)) do anything about this porblem Any help/advice would be appreciated. ...Show All

• Webbert why OpenEvent will return NULL

  Hi Everyone: i have a application and a service(which run on LocalSystem),the service will a Create a gloable Event, and App will Open this Event. It seems ok on NT/XP, but on vista, when App Open this Event, it will return handle NULL. this is why Thanks The corresponding error code (from GetLastError() right after the failing OpenEvent) would be most useful in confirming this but: If it's 5, it's likely that the event is not ACLed properly so that it can be opened with the access required by the application (which probaly ran as admin on XP, and not anymore in Vista). If it's 2, it's likely that the application doesn't specify Global\ when calling OpenEvent (on XP, applications often run in session 0, and on Vista, they never ...Show All

• PeteJM01 Listen Activity in state machine workflows

  Hi, Can we use listen activity in state machine workflows. Here is my case, where i need to use listen activity, (which i thouht it would be better) I have created state machine workflow for my web application and when web app raises some events, i have to change the state of my workflow from one state to another. In the workflow, I have an event, which executes sequence of 7 steps. When user clicks a button in my aspx page, i am raising the event and the event performs all these 7 steps. Its working fine! Now i got another requirement, that user can raise one more event (from other button, but the state remains the same), which is very similar to that of former, but it has one different step at #2 position of sequence. The rest of the seq ...Show All

• Ken Camann Any licensing required using WWF?

  Hi All Had this question in my mind before making a sw product out of WWF for my business. Have around 50 licenses for VS 2005 Developer's Edition. Now creating some workflows in new sw products. Download WWF Extensions for VS 2005. These extensions have the WWF Debugger & the WWF Designer in them. Do I need any additional license to use these Extensions in my products. Thanks VK Thanks Razi :) Hi Vishal No you dont need any additional lisence for that ! , moreover as WF is integral part of .NET Framework 3.0 you can leverage it without having to purchase any other lisence (same as .NET Framework 2.0 and .NET Framework 1.x ) If you also h ...Show All

• batfox transforming all input to RGB24 type

  Hi! I've been looking through many examples and forums... I think I need something not too complicated, but I haven't figured what to do. At the moment my Graph is: Video Input (USB camera or video card on PC) | Sample Grabber (with callback that provides RGB24 format easily transferred to BMP) | Null Renderer I now have to use many other USB cameras that do not necessarily output RGB24 type video. I need to add a Transform Filter (DV Video Decoder ) that will translate any Video type that's not RGB24 into RGB24 so that the Sample Grabber will continue working OK. I know it should be simple - but I'm a "newbie" and have no idea to do this. Any idea or sample, etc. will ...Show All

• Bluehunter Is there any way (API) to turn off Aero to enable video overlay?

  My application uses hardware overlay that can not display on Aero. So I want to turn off Aero Grass by my application. Is there any API for killing Aero ( SystemParametersInfo ) Or any other way ( stop some services. ets... ) I found a resolution to my problem on Friday on how to disable the Vista Aero theme while doing our desktop sharing session and then re-enabling it once we're done. The root to my solution was found on a fellow by the name of Kenny Kerr's blogg http://weblogs.asp.net/kennykerr/archive/2006/08/10/Windows-Vista-for-Developers-_1320_-Part-3-_1320_-The-Desktop-Window-Manager.aspx and all I needed to do was perform so retro fitting of Kenny's solution into my code ba ...Show All

• Oliver 123 how to change the text shown when dragging activities from the toolbox

  Can someone please explain, how I can programmatically change the text, that is shown, when I drag activities onto the designer surface By default, the class name is shown (for example in the designer rehosting example). Matt, thanks for your help. Unfortunately your code did not work in my case. I tried your code in the OnPaint of a customized activity, that I have added to the Designer Rehosting example, that you will find at http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnlong/html/WFDsgnRehst.asp The class name is still shown in the designer when I drag items from the toolbox and not " the custom display text ". I have the feeling that the reason has something to do with the ToolboxSe ...Show All

  Hi, 1. How can I play a YUV file with format YUV 4:2:0 2. Can I render from file that I am writing to at the same time (with delay of-course) Thanks, Yaniv Using graphedit can help determine if the problem is your code or something directshow related.

• thrice SqlTrackingQuery unable to retrieve RuleActionTrackingEvent when PartitionOnCompletion is true

  I'm running RC1 of WF and I noticed some odd behavior with tracking. It seems that if you set PartitionOnCompletion to true for the SqlTrackingService, the SqlTrackingQuery is unable to retrieve any any RuleActionTrackingEvent objects. If I turn PartitionOnCompletion on and run a simple workflow containing a RuleSet, I get nothing when I check the UserEvents property of SqlTrackingQuery. However, if I turn PartitionOnCompletion off, the UserEvents magically appear. Is this a known bug in RC1 with partitioning or the SqlTrackingQuery class Thanks.
