Is SetCursorPos() Calling MouseMove ?
-
Hello Friends OnMouseMove ,After drawing some color stripes,I am using SetCursorPos(x,y) to Set MousePosition manually at end of stripe. But As I move Only once after that mouse keeps on moving by itself until I dont release mouse lbutton up. I am assuming that setCursorPos is calling MouseMove so it is going in Infinite Loop. But,In actual I want to stop mouse pos at end of stripe while mouseMove. Here is the Flow : 1.)LButtonDown 2.)MouseMove(drawing stripe then setCursorPos() calling) [want mouse cursor at end of stripe] And again if Mousemove,strip should draw and cursor at end of Stripe. 3.)LbuttonUp[releasing the mouse] Any Ideas?? Regards Yogesh

Just remember in a "global" variable that you have done the movement so that you can then ignore OnMouseOver the next time.

If you're drawing in
MouseMove, why do you need to callSetCursorPos. Please post some relevant code so that we can understand the problem better.«_Superman_» _I love work. It gives me something to do between weekends.

Hello As I told that OnMouseMove I am drawin gsome color stripes on Ruler Scale . Suppose scale is from 1 to 10 and If i am clicked on 2 and moved a little then it draws stripe of 5inch width.after that i want cursor should come at 7th Inch. So,for that i used SetCursorpos to move mouse manually after end of drawn stripe. Any IDeas ? Regards Yogesh

The question is not clear to me, but let me answer with what I think the question is. An
OnMouseMovehandler is called when the mouse is moved over a window. WhenSetCursorPosis called, it does not normally callOnMouseMove. But if the new cursor position as a result of callingSetCursorPosis over the window for which theOnMouseMovehandler is created, then it will be invoked. If that is the case, you will need to set a flag before callingSetCursorPosand then check this flag insideOnMouseMoveto distinguish between manually moving the mouse and callingSetCursorPos. Remember to reset this flag insideOnMouseMove.«_Superman_» _I love work. It gives me something to do between weekends.

Hello As U suggested that I need to set a flag before calling setCursorPos to check on MouseMove. Suppose If this flag satisfies the condition on MouseMove that movement is through SeCursorPos then it will return from there and then how will i reset tht flag on MouseMove. Here is sample Code for this:
void CMarkWnd::OnMouseMove(UINT nFlags, CPoint point)
{
if(GetCapture() != this) return;//----Calling my own Code to Draw Stripe---//
// Doing Some calculation to Find the Width---
// and then setting Mouse Cursor Position---------SetCursorPos(x,y)
CWnd::OnMouseMove(nFlags, point);
}Thanks Yogesh

Please check the lines in bold. That should do it.
void CMarkWnd::OnMouseMove(UINT nFlags, CPoint point)
{
if (mouseFlag)
{
mouseFlag = false;
return;
}
if(GetCapture() != this) return;//----Calling my own Code to Draw Stripe---//
// Doing Some calculation to Find the Width---
// and then setting Mouse Cursor Position---------mouseFlag = true;
SetCursorPos(x,y)CWnd::OnMouseMove(nFlags, point);

Hello. I tried as u suggested but still Mouse is keep on Moving on my First move. Thanks Yogesh
Try to debug and find out what is happening.

Hi, Rather than using
SetCursorPosyou could use the SendInput function[^]. This would allow you to set some 'extra info' for marking simulated user input. For example:BOOL setcursorposition(long x, long y)
{
INPUT input = {0};
input.type = INPUT_MOUSE;
input.mi.dx = ((x - GetSystemMetrics(SM_XVIRTUALSCREEN)) * 65535) / (GetSystemMetrics(SM_CXVIRTUALSCREEN)-1);
input.mi.dy = ((y - GetSystemMetrics(SM_YVIRTUALSCREEN)) * 65535) / (GetSystemMetrics(SM_CYVIRTUALSCREEN)-1);
input.mi.dwFlags = MOUSEEVENTF_VIRTUALDESK | MOUSEEVENTF_MOVE | MOUSEEVENTF_ABSOLUTE;
input.mi.dwExtraInfo = 0xC0DEDBAD;
return SendInput(1, &input, sizeof(input));
}void YourClass::OnMouseMove(UINT nFlags, CPoint point)
{
if(0xC0DEDBAD != GetMessageExtraInfo())
{
//You would ignore the simulated input and do your processing here
}
YourBaseClass::OnMouseMove(nFlags, point);
}Don't forget to convert client coordinates to screen before calling setcursorposition. Best Wishes, -David Delaune
