I create a hidden listbox, when an edit box shows the listbox when get the input focus, found the listbox cannot response message,

CodePudding user response:

How does not respond??

CodePudding user response:

Is such as one of the items you choose, not into my selchange message processing function

CodePudding user response:

This message is sent by an application when the selection in a list box is about to change. The parent window of the list box receives This message through the WM_COMMAND message.
Your ListBox control's parent window is which?

CodePudding user response:

This message is not sent if the LB_SETCURSEL message changes the selection.

This message applies only to a list box that has the LBS_NOTIFY style.

For a multiple - selection list box, the LBN_SELCHANGE message is sent whenever the user presses the an arrow key, even if the selection does not change.

CodePudding user response:

Is ah, in the main window window created by the MFC based on the project window,

CodePudding user response:
