Custom Report Preview Control Toolbar
Note: The original VFP print preview is much more convenient. Under some specific requirements, she is very awkward, especially the printer on the print toolbar, and print it at a point. At that time, we need to make selective printing instead of the whole discharge, nor is it very troublesome to close the print preview to return to the printed print, so this update is in the original custom report preview window. And based on the total number of reports of the report, add a custom toolbar to make the program more personalized.

Festival velocity, you can use some text processing software to replace all the double-byte spaces "" all the single-byte space!
