• Will Merydith WlanSetProfile() returns "Element Not Found"

  I am working with the Vista 802.11 Auto Configuration APIs for my UI.

• Lee Hudson Using DirectShow for Accessing Video/Audio from IP Cameras

  I am developing an application to access ip cameras over my network and display them on my Web Page with 3 PictureBoxes. The frames should be watched over these PictureBoxes in real-time. The project is a Surveillance Application which controls network cameras ( ip cameras ) through the server pc. I could found nothing on the internet except that an ip cam has a webserver running inside which sends its frames to an http page to be watched over internet but I'm not sure if that is 100% correct and common for all ip cameras. The problem is with the IP Cameras, because I’m not sure about their underlying working mechanism. In their softwares they mostly send frames to a web page which can be watched over internet or LAN. Do they all work t ...Show All

• kiwilamb [BUG] Vista doesn't start application called "install" w/o being elevated.

  Hi, I just encountered this really strange behaviour, which is definitely a bug in Vista. Consider the following situation. You're logged in as an administrator account. Start a CLI shell of your choice, start it normally, so that it's running non-elevated. Now consider a console application called install.exe. It's neither a GUI application, nor is it an installer application in the Windows sense. It's just called install.exe. In my case it's part of GNU coreutils and it's called install because it's usual task is to install software on the system. However, it's perfectly valid to call install as normal user and use it to install stuff into a subdirectory on which you have permissions. This is what happens when running under Cygwin (proce ...Show All

• redneon Context Menu - Workflow Designer Sample

  Hi. I am building on top of the Workflow Designer sample and am trying to add context menus to the activities on the design surface. I have been able to use ISelectionService to get close to the intended effect but did not find a way to determine when a right-click raises the event and when a left-click raises the event. I think that maybe ISelectionService is not the correct approach, but am having trouble figuring out where and how to create and bubble up the event. Thanks in advance! Look at the WorkflowDesignerMessageFilter class in the docs. The docs will point you to a sample in the SDK. This class has a method, OnShowContextMenu, that will signal you to show your context menu. You can then eith ...Show All

• 1Dave Workflow from markup and SQL persistence

  I've some workflow markup files, and I create workflow instance from files in the host. Those workflows contain a delay activity, which would do something which timeout duration is expired, they work fine until workflow host is restarted. If I shutdown workflow host and restart it, it will load persisted workflow from sql database if timer expire, but it do not run the code activity under the delay activity, and it do not have any exception. I've placed many breakpoint in my workflow, however, it did not fired any one of them, workflow is completed and removed from sql database finally. Does anyone have any ideas about this issue Or is there any methods I can debug the workflow when it is resumed after a host restart Thank you very much!! ...Show All

• Sweed Binding Dependency properties in a hosted Workflow

  I have a custom activity to use in a sequential workflow. This activity has a dependency property. When I add this activity into a workflow console application, am able to use the 'blue' colored bullet to bind this property to a preceeding property of same type. When I use the designer control and hosting example as in lab10, the 'blue' colored bullet does not appear. Is is something that am missing, or is it that the designer control in lab10 is priliminary not addressing all cases Am using RC2 version of WF. I have found the solution.
