In Visual C , the application is usually used in ONPRINT () or OnDRAW () in Onprint () or OnDraw (). But for data in the dialog, or printed into a cumbersome work based on the dialog. This section provides the user with the PrintListCtrl () function for printing the contents of the user in the dialog or FormView (the control must be the form of the Report View) control. During the printing process, the width of the columns when the printout is calculated according to the width of each column title in the control, and automatically pane according to the number of lines of the data. On the basis of this code, it can be adapted to the output of various data. (Usage :) This segment code uses Visual C 6.0, use the Windows API to complete the desired function, use this text as header files. Call directly of PrintListCtrl (), and the parameters of the function are the listctrl to be printed. ?
