Context menu pops up in the show, the specified control and location, can be specified in the control system of position pop-up,
This problem is a lot of you, also very few ^ ^
Take the mouse to click the listbox item has several procedures, can use the API to send SENDMESSAGE LB_ITEMFROMPOINT=& amp; H1A9 news, it is important to note the mouse coordinates of coordinate system, also can be directly calculated, give you a little code, look at yourself:
