I assume the logic to determine the time is in your child dialog. If that is the case,

1) If you used GetCursorPos(...) to get your point, then you have to call ScreenToClient(...) to convert them to client coordinates.

2) Then before you display your child dialog with DoModal(), store these coordinates in your child dialog.

ScreenToClient(...) takes 2 parameters, first one is a handle to your window, the second is your point. Since you are calling this in your child window, then you have to call GetParent() to get the handle to your parent window and pass it into ScreenToClient(...). e.g.

GetCursorPos(&cp1);
HWND hParentWnd = GetParent(/* Handle to your child window */);
ScreenToClient(hParentWnd, &cp1);

I Think following change sholud be there in program.

<br />
::ScreenToClient(hParentWnd, &cp1);

Check the Scope Resolution Operator( :: ) before ScreentoClient API.

I Think this correction should be there.

Try putting the scope operator asMahesh have pointed out:

GetCursorPos(&cp1);
HWND hParentWnd = ::GetParent(/* Handle to your child window */);
::ScreenToClient(hParentWnd, &cp1);

Re: urgent please slove it as quickly as possible [modified]

18-Jun-06 23:34

Didn't you said you are calling it from OnTimer of your child window? If that's the case, then you should get the handle of that window for GetParent(...).

Btw, are you using mfc?

happy_ram19-Jun-06 0:39

If you are using mfc, then you can do this:

// Get pointer to parent window and then convert screen coordinates
AfxGetMainWnd()->ScreenToClient(&cp1);
