batch-file

问题 I had a problem with set not working in a batch file; it took a while to distil the problem; at first I thought it was to do with subroutine calls... The script @echo off setlocal set a=aaa echo a = "%a%" ( set b=bbb echo b = "%b%" ) produces the output a = "aaa" b = "" whereas I'd expect a = "aaa" b = "bbb" Why is this please? Is it a bug in DOS? Perhaps there's something about the (...) command grouping syntax that I'm unaware of. Thanks. 回答1: User delayed expansion and ! instead of % @echo

问题 I have written a program that will change the foreground window to 85% of the monitor's dimensions and to run successfully the foreground window needs to remain the same. I have put the python script (.pyw) into a batch file (running pythonw) and created a shortcut to the batch file on the desktop with a shortcut to run it quickly. I also made it run the batch file minimized but it still switches the foreground window to the minimized command prompt. Per the python code below I am using
