Hi,
In one of my samples i am loading and setting a cursor from a dll.
But cursor is not redrawn immediately after calling SetCursor().
Newly loaded cursor will be shown only if a mouse move occurs.
Can any one help me

Solution 2

The SetCursor function is also called by the default window procedure every time the mouse is moved if it is not captured, and set back to the one used to register the windowclass.

If you want the cursor associated to a window to reshape, you've to call SetClassLong [^]and change the associated cursor.

I have already tried using SetClassLong(). This will also take effect after a mouse movement :(

Try forcing the mouse to move with GetCursorPos / SetCursorPos one pixel back and forward.

I am calling SetcursorPos() to set the cursor position. But it wont work.

Solution 1

The cursor won't get redrawn until the form that it's sitting over gets refreshed or the mouse moves.

Frankly, if you're setting the mouse cursor from a .DLL that is supposed to do work and not UI stuff, you're setting the Cursor from the wrong place.
