问题 I have this line of code: convert 1234_Page_1_....png 1234_Page_2_....png output.pdf This merges those particular pngs to a single pdf (using ImageMagick). I have a bunch of files in this format. I would like to perform this merging/converting-to-pdf action on files that have the same number before the " Page ". Sometimes there are more than two pages to convert.

问题 I have a server which receives commands from a client and runs them. These commands use one specific batch script, which receives arguments and runs. The script calls an external console application program with these arguments. The arguments can also instruct the script to run multiple instances of the console application, in the background. So, the outcome could be one open CMD , running 3 instances of app.exe , in the background. I wish to know when each one of those processes of app.exe

问题 I'm creating A Small Program To Help With The Infamous Windows Update Fail in Windows 7! What I'm Using Is A Batch But For Some Reason The "echo." isn't showing blank lines. Any Ideas.

问题 %errorlevel% doesn't work in WindowsXP. As I know when an error occurs %errorlevel% set 1 or above value, and if there is no error it will set 0. But, even though there is no error, %errorlevel% is 1. And I set %errorlevel% 0, even there is an error %errorlevel% is sill 0. I think OS doesn't change %errorlevel% in XP. In Win7 it work totally. @echo off setlocal enabledelayedexpansion call dir echo errorlevel=%errorlevel% REM expected errorlevel=0 but 1 call dor echo errorlevel=%errorlevel%
