how can I capture mouse wheel click/press in Silverlight 4? I can detect its rolling using delta in mousewheel event, is there any way to detect its press? I use VS2010/C#
The mouse wheel click would be a middle mouse button event. Unfortunately the middle mouse button is not supported in Silverlight 4. Consider alternatives such as cntrl + left click, especially as many computers won't have a middle mouse button.

I have a WSAWaitForMultipleEvents based loop, that (in addition to other stuff), triggers on keyboard and mouse events. Firstly setting:
SetConsoleMode(GetStdHandle(STD_INPUT_HANDLE), ENABLE_EXTENDED_FLAGS | ENABLE_PROCESSED_INPUT | ENABLE_MOUSE_INPUT);
And then using:
GetStdHandle(STD_INPUT_HANDLE);
As an event added to WSAWaitForMultipleEvents .
Now this is working fine but I'm really only interested in the mouse position when clicked. But naturally it is triggering for mouse movement as well. Is there any way of excluding mouse movement from the event such that WSAWaitForMultipleEvents will only awaken on mouse click and will ignore mouse movement?

No. Using ENABLE_MOUSE_INPUT means that the console handle satisfies the wait on any mouse activity within the console window while the window is focused. That includes both mouse movements and mouse clicks. The documentation even says as much. So, you will just have to receive and discard the console events that you are not interested in.
I need to provide panning and zooming capabilities to my image in WPF. I have followed the below link and it works fine for Touch screen based system.
Multi touch with WPF . But what it doesn't work with ,mouse events. such as scrolling the mouse wheel to zoom or rotating the image using mouse. below are my questions?
Is there any possibilities to achieve both mouse and touch events by means single event?
IF yes how to do that?
If it is not possible, Why?
There are no such Common thing except the click events like MouseLeftButtonDown,MouseDown ... You have to Implement your own logic for Touch and Mouse Based Interaction.
Because they are not the same
Take a touch and drag, and a click and drag, superficially the same
But a click can be left, right, middle, special, it can be multiple buttons at once, none of that has anything to do with a touch
likewise a touch pinch has no meaning as mouse scroll wheel event
So you need to capture the different Events and convert them into a meaningful command that the VM can perform
I'm using a horizontal slider in WPF, but would like to also perform some action if the mouse is moved vertically (like change the brightness of some control).
I tried responding to MouseMove, but I don't get an update when dragging the slider, if the mouse moves purely vertically - my function only gets called when the slider actually moves.
You could attach a handler to the slider's PreviewMouseMove event.
I'm trying to write a WinForms program that will capture mouse coordinates upon pressing and (more importantly) releasing the middle mouse button.
My form has topmost set to true (so that text in it can always be visible even when it doesn't have focus).
What I'm aiming for is being able to hover the mouse over a game window after my program starts, hit the middle mouse button, and have it record the mouse position for later use.
I can get it to detect when the middle mouse button is clicked inside the form using the MouseUp event (bound to the form itself) but have no clue what I need to do to have it detect when the mid mouse is clicked outside my form.
Thanks for any help guys.
I believe what you are after are called low level hooks. A quick google brings up this: Erroneous Mouse Coordinates Returned from Low Level Mouse Hook C#
A microsoft example of how to do can be found here: http://support.microsoft.com/kb/318804
I have an slider control in my application and an image control. When the slider value is going up, the image is zoomed in and vice versa.
In addtion i have a zoom-in and a zoom-out button. the zoom-in button will increase the slider value by one smallchange and the zoom-out will decrease it.
What i want: while the zoom-in (and out) button is pressed i want to slider to keep increasing(performin a zoom in) and not just one time.
In other words, as long as the left button is pressed, i want to keep performing the mousebuttonpressed on the button until the mousebutton is released.
Oh, by the way, im using Silverlight 3.
Thanks.
You can use the RepeatButton class to do this. It raises it's click event repeatedly while held down, much like the thumb of a scrollbar or an up/down spinner.
