Handle+mouse_event

Re: Handle+mouse_ev ent

Abhishek,

The Handle property on the control will return the handle that you are
looking for.

Hope this helps.

Hi,

how do I pass the handle of a control to the win32 api mouse_event. so
that it will create the click event on that application only even if there

Re: Handle+mouse_ev ent

Hi Abhishek,

Are you trying to send mouse input to a different process? You'll have to obtain the window handle by enumerating the windows in
the process and view the text and type to find the specific control. There a Win32 API functions that you can use such as
EnumWindows and EnumChildWindow s.

To simulate a click in your own application obtain the handle of the control from the Control.Handle property.

In either case after you retrieve the handle pass it to the external SendMessage Win32 API function along with WM_LBUTTONUP.

(Note that a few controls in the framework have a PerformClick method, which will alleviate the need for interop if you can use
them.)

Re: Handle+mouse_ev ent

Hi Abhiishek,

Try sending WM_LBUTTONDOWN and then WM_LBUTTONUP and specify the control's handle using the Control.Handle property. I doubt this
will work cross-process but you could try to obtain the handle to a window in another application using the EnumWindows or
EnumChildWindow s Win32 API functions.

private void SimulateClick(C ontrol ctrl)
{
if (ctrl == null)
throw new ArgumentNullExc eption("ctrl");

int x = 8, y = 8;
int point = x + (y << 16);

SendMessage(ctr l.Handle, WM_LBUTTONDOWN, 0, point);
SendMessage(ctr l.Handle, WM_LBUTTONUP, 0, point));
}

private const uint WM_LBUTTONUP = 0x0202, WM_LBUTTONDOWN = 0x0201;

[DllImport("user 32.dll")]
public static extern int SendMessage(Int Ptr hwnd, uint msg, int wparam, int lparam);

Re: Handle+mouse_ev ent

Hi All

Getting the handle of the contol is not the problem. if I have a game
running then the mouse event does not function (with mouse_event). the
sendmessage is not working at all, the application gets focus but the click
event is not happening.

SendMessage(axW ebBrowser1.Hand le, WM_LBUTTONDOWN, 0, point);
SendMessage(axW ebBrowser1.Hand le, WM_LBUTTONUP, 0, point);

This is the mouse_event
mouse_event(MOU SEEVENTF_LEFTDO WN, 0, 0, 0, new System.IntPtr(0 ));
mouse_event(MOU SEEVENTF_LEFTUP , 0, 0, 0, new System.IntPtr(0 ));

Abhishek

Re: Handle+mouse_ev ent

Hi Abhishek,

Is your 'game' by any chance tying up the UI Thread? You'd have to call Application.DoE vents() in that case to allow the Control
some time to process your mouse notifications, however a better program architecture would be more appropriate.

Actually, after reviewing your post a second time I'm not so sure I fully understand the situation.

Do you have two applications running simultaneously and you are attempting to get one application to send a mouse notification to
the other? If so, are both apps managed code?
Do you have a single, managed application with two visible Forms and you are attempting to send a mouse notification to a control on
the unfocused Form?

Please clarify. I'd like to help if I can.

Re: Handle+mouse_ev ent

Hi Dave,

i am trying to create a ingame brower window. for this my dll is creating
bmp's of the embedded browser which present on a win form. This DLL is
loaded by my proxy directx 9 dll which is called by the game. this give me
real time render. I can watch youtube video's in game without a single
frameskip. the next step for me is the recreate a ingame click on a location
x, y in my browser. so that the navigation happens seamlessly. they are both
one below each other in placement(start x and y for both ingame and out of
game is 0,0 for now).
below are the two functions that should be able to handle this. the
mouse_event work perfectly when the browser is visible on screen.but
otherwise it down not. which is why i wanted to know if you can pass the
handle of the browser like in SendMessage so that the click happens in that.

In sendmessage the form becomes formost but no click happens.
private const int MOUSEEVENTF_LEF TDOWN = 0x2;
private const int MOUSEEVENTF_LEF TUP = 0x4;
private const uint WM_LBUTTONUP = 0x202, WM_LBUTTONDOWN = 0x201;

public unsafe void createleftclick () {
int x = 8, y = 8;
int point = x + (y << 16);
SetCursorPos(8, 8);
SendMessage(axW ebBrowser1.Hand le, WM_LBUTTONDOWN, 0, point);
SendMessage(axW ebBrowser1.Hand le, WM_LBUTTONUP, 0, point);
SendMessage(axW ebBrowser1.Hand le, WM_LBUTTONDOWN, 0, point);
SendMessage(axW ebBrowser1.Hand le, WM_LBUTTONUP, 0, point);
}

public void SendClick(int px, int py)
{
SetCursorPos(25 , 25);
mouse_event(MOU SEEVENTF_LEFTDO WN, 0, 0, 0, new System.IntPtr(0 ));
mouse_event(MOU SEEVENTF_LEFTUP , 0, 0, 0, new System.IntPtr(0 ));
}

My directx dll will just call the function directly

Abhishek

Re: Handle+mouse_ev ent

Hi abhishek,

Interesting idea but I have no idea what the browser is doing with your messages. Since it is a browser, after all, why not just
call ExecScript and perform a click in the actual browser using something like the following:

<script language="JavaS cript">
function performClick(x, y) {
obj = document.elemen tFromPoint(x, y);
if (obj.click)
obj.click();"
}
</script>

MSDN object.click() method reference:

http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/reference/methods/click.asp

If you are using the 2.0 framework's WebBrowser control:

browser.Documen t.InvokeScript( "performCli ck", x, y);

For the ActiveX browser use the ExecScript method from IHTMLWindow2 to call the function.

Re: Handle+mouse_ev ent

Hi Abhishek,

Does SendMessage return 0 when you send WM_LBUTTONDOWN or UP?

Either way, I think your out of luck with this approach (see my other post) but if it's non-zero that would indicate an error and
you should go from there.

Re: Handle+mouse_ev ent

cant use the script :(

Since this will just create a event on a link. bit of there is flash open
then? I will get the object of the flash and the click will not happen on
the button that is in the flash. also mouseovers and other stuff will not
happen. I need to create actual in game browser with all the bell and
whistles there is also the issue of scrollbars that need to be dragged

so my best bet is to use something like sendmessage, which is returning
zero. maybe there is a click happening just not at 30,30 the point i am
sending the cursor to.

Abhishek

Re: Handle+mouse_ev ent

Hi Abhishek,

Well you still might be able to use scripting if the Flash object model supports simulating a mouse click at a certain point. Check
if Flash also supports raising a mouse over event and scrolling from script while your at it.

so my best bet is to use something like sendmessage, which is returning zero. maybe there is a click happening just not at 30,30
the point i am sending the cursor to.

You must send the point to the SendMessage function. It doesn't matter where the cursor is actually located on the screen for
SendMessage with WM_LBUTTONDOWN.

To verify that SendMessage is working, since it is after all returning zero, why don't you replace the browser with a Button and in
a Click event handler show a MessageBox. Try to click the button with SendMessage. If it works then I suspect the problem is with
the browser and script might be your only option.

Re: Handle+mouse_ev ent

Hi Dave

Thanks for all the help finally got it working.
the issue was not with sendmessage. the issue was the since the browser was
a activex control the normal browsername.han dle did not work here. I had to
first use getwindow and GetClassName to find out the handle and then use
that in sendmessage.

but thanks a lot. it really helped.

regards
Abhishek
