问题 I've two VB Scripts. Say First.vbs and Second.vbs . Frist.vbs calls Second.vbs each time some action/event happens. I am trying to send two parameters from Frist.vbs to Second.vbs using the following code: Contents of First.vbs : Set objShell = Wscript.CreateObject("WScript.Shell") param1 = "Welcome" param2 = "Gokul Nath" objShell.Run "Second.vbs" & " " & param1 & " " & param2 Set objShell = Nothing Contents of Second.vbs : param1= Wscript.Arguments.Item(0) param2 = Wscript.Arguments.Item(1)

问题 In Bash I'm executing a command and putting the result in a variable like this: export var=`svn ls` But if SVN fails for some reason--say it returns a non-zero error code--export still returns status code 0. How do I detect if the executed command fails? 回答1: var=`svn ls` if [[ $? == 0 ]] then export var else unset var fi $? is the exit code of the last command executed, which is svn ls here. jmohr's solution is short and sweet. Adapted mildly, var=`svn ls` && export var || unset var would be

For example, I may call it like this now: DoSomething-ToTask 1 2 3 ..and like this later DoSomething-ToTask 4 The second example works, but the first

问题 I just discovered AutoHotKey and it seems like a dream come true. I have two .ahk scripts, A.ahk and B.ahk . I want to call script B from within script A. The AHK forums are strangely silent on the subject but I am sure this is possible. 回答1: It's the #Include directive you are looking for.

问题 As usual, I create an error-handler using On Error Goto statement, there I put a few lines of cleaning codes and display the error message, but now I don't want to lose the comfortableness of the default handler which also point me to the exact line where the error has occured.
