Set Windows To Control/manage Wireless Over Third-party Clients?
Jun 6, 2011Within VB.NET, trying to find an easy way to in a sense check the check-box "Use Windows to configure my Wireless Network Settings". This is an option that forces windows to use your wireless over third-party programs that may try to steal control. I am aware this requires to have WZC enabled within services and that's something that can be easily accomplished one way or another.
I doubt or rather cannot find a proper registry value or API call to check or initiate such a task.

View 3 RepliesControl Arrays - Allocating Multiple Camera Objects Dynamically
Jan 19, 2009I have a VB.NET application and use some third party (closed source) ActiveX controls. One of the controls represents a "camera" (connected over several interfaces) and I try to write an example how to work with several cameras in one application. To do this I allocate multiple "camera" objects dynamically as an array which works as expected like this:
Const NUM_CAMERAS = 2
Private MyCameras(NUM_CAMERAS ) As xxx.MCamera
But the camera objects needs to be allocated with WithEvents because they raise events when a new image was taken. I found out that WithEvents variables cannot be typed as arrays and this is a pretty common problem so I also found some workarounds: [URL]. This is already pretty good and I adopted this to my concept. So I have a MyCameras array and a MyCamera all "without Events", first allocate a new MyCamera object, add a event handler and then put it into the array.
Unfortunately I get an error when calling
AddHandler Camera.ProcessModifiedImage, AddressOf MyHook
Normally "MyHook" is declared as
Private Sub MyHook (ByVal sender As Object, ByVal ModifiedBuffer As xxx.ProcessModifiedImageEvent) Handles Camera.ProcessModifiedImage
Like in the "Button examples" I just removed the "Handles Camera.ProcessModifiedImage" but I get an error that "MyHook" has not the same signature as the Delegate
Delegate Sub ICameraEvents_ProcessModifiedImageEventHandler(ImageIndex as Integer)
