我必须使用run执行批处理文件,并在文本文件中获取输出,并在该文件中搜索代码片段的字符串,如下所示,
用于运行bat文件
Set objShell = WScript.CreateObject("WScript.Shell")
MsgBox("Compiling Source files..Please wait..")
objShell.Run CHR(34) & ".\lib\Compile.bat" & CHR(34) & " > compile.txt" & CHR(34), 0 ,True
我发现运行后执行不会进入下一行,但如果我在任务管理器中结束cmd.exe进程,则会执行。
我已经提到了在下面这个读完之后等待过程完成的事实,
Dim objFSO, strLine, objReadFile
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objReadFile = objFSO.OpenTextFile("./compile.txt", 1 , true)
Do Until objReadFile.AtEndOfStream
strLine = objReadFile.ReadLine
....
....
如何执行compile.bat并且正在创建compile.txt但是不会发生读取过程。如果我从运行命令中删除“true”,则会收到“compile.txt文件不存在”错误。
我不知道哪里出错了,请帮帮我..

从你的所有问题我都假设你的问题背后的故事 是这样的:
你的老板D. Vader先生,要求你开发构建系统 他的Java应用程序。 “好的”,你说,“让我们使用Eclipse和/或Ant。” “没有”,维德先生说,“我们将拥有一支现代化的BS,其中包括.BAT和一个 按钮GUI“。
所以你建立了一个实验项目:
tree /a /f .
E:\TRIALS\SOTRIALS\ANSWERS\19944721
|
+---vbs
| | javacompile.hta
| | javacompile.vbs
|
\---java
+---good
| Good.java
|
\---bad
Bad.java
从最小的Good.java开始:
class Good {
public static void main(String[] args) {
System.out.println("use Eclipse!");
}
}
你确认了:
javac Good.java
- no news are good news --
echo %ERRORLEVEL%
0 <-- javac may set ERRORLEVEL
java Good
use Eclipse! <-- it works
坏的相同程序:
class Bad {
public static void main(String[] args) {
System.out.println("D. Vader says: 'Use .bat and one button GUI!'.");
}
javac Bad.java
Bad.java:4: reached end of file while parsing
}
^ <-- javac finds the missing }
1 error
echo %ERRORLEVEL%
1 <-- javac really sets ERRORLEVEL
然后你编写了最小的GUI:javacompile.hta
<html>
<head>
<Title>JavaCompile</Title>
<hta:application id="javacompile" scroll = "no">
<script type="text/vbscript" src="javacompile.vbs"></script>
</head>
<body>
<form>
<input type="button" id="bttCheckBasics" value="Check Basics"/>
<form>
</body>
</html>
和'后面的代码'javacompile.vbs
Option Explicit
Dim goFS : Set goFS = CreateObject("Scripting.FileSystemObject")
' document.location: "file:///E:/trials/SoTrials/answers/19944721/vbs/javacompile.hta"
Dim gsVbsF : gsVbsF = Replace(goFS.GetParentFolderName(Mid(document.location, 9)), "/", "\")
Dim gsJavaF : gsJavaF = goFS.GetAbsolutePathName(goFS.BuildPath(gsVbsF, "..\java"))
Dim gsGoodF : gsGoodF = goFS.BuildPath(gsJavaF, "good")
Dim gsBadF : gsBadF = goFS.BuildPath(gsJavaF, "bad")
Sub bttCheckBasics_onclick()
MsgBox "Sub bttCheckBasics_onclick() was called."
MsgBox Join(Array("Known Folders:", gsVbsF, gsJavaF, gsGoodF, gsBadF), vbCrLf)
End Sub
并验证GUI知道在哪里(并且自动绑定有效)。
(Copy from MessageBox)
Known Folders:
E:\trials\SoTrials\answers\19944721\vbs
E:\trials\SoTrials\answers\19944721\java
E:\trials\SoTrials\answers\19944721\java\good
E:\trials\SoTrials\answers\19944721\java\bad
---------------------------
OK
---------------------------
为了让球滚动,你在.hta
上添加了一个按钮 <br/>
<input type="button" id="bttKiss" value="Keep It Simple, Stupid"/>
和vbs的一些代码:
Sub bttKiss_onclick()
MsgBox "Sub bttKiss_onclick() was called."
KissCompile gsGoodF, "Good.java", "bgood.bat"
KissCompile gsBadF, "Bad.java", "bbat.bat"
End Sub
Sub KissCompile( sF, sJava, sBat)
goWSH.CurrentDirectory = sF
Dim sCmd : sCmd = Join(Array("javac", sJava))
Dim oExec : Set oExec = goWSH.Exec(sCmd)
Do Until cnWshFinished = oExec.Status : Loop
MsgBox Join(Array(qq(sCmd), "(javac) ExitCode:", oExec.ExitCode))
If 0 <> oExec.ExitCode Then MsgBox oExec.StdErr.ReadAll(), vbAbortRetryIgnore, "You messed it up, Mr. Vader!"
End Sub
Function qq(s)
qq = """" & s & """"
End Function
现在,GUI显示两个MessageBox,用于坏情况:
---------------------------
"javac Bad.java" (javac) ExitCode: 1
---------------------------
OK
---------------------------
---------------------------
You messed it up, Mr. Vader!
---------------------------
Bad.java:4: reached end of file while parsing
}
^
1 error
---------------------------
先生。维达并不觉得好笑:整个地方都是黑色的窗户而不是单一的.BAT!
你设置goWSH.CurrentDirectory
的巧妙技巧并不令人印象深刻
他一点都没有。
所以你写了bgood.bat:
@echo off
javac Good.java
IF ERRORLEVEL 1 GOTO :bingo
echo SUCCESS
GOTO :end
:bingo
echo FAILURE
:end
和相应的bbad.bat。一些测试:
bbad
Bad.java:4: reached end of file while parsing
}
^
1 error
FAILURE
JAVA E:\trials\SoTrials\answers\19944721\java\bad
echo %ERRORLEVEL%
1
现在故事改变为科幻小说。你会按照我的建议去做 使用我的BTicks function略微修改以更好地处理目录并减去删除日志文件的错误。所以util.vbs看起来像
Option Explicit
Const cnWshRunning = 0 ' The job is still running.
Const cnWshFinished = 1 ' The job has completed.
Const SW_SHOWMINNOACTIVE = 7
Const ForReading = 1
Function qq(s)
qq = """" & s & """"
End Function
' BTicks - execute sCmd via WSH.Run
' aRet( 0 ) : goWSH.Run() result
' aRet( 1 ) : StdErr / error message
' aRet( 2 ) : StdOut
' aRet( 3 ) : command to run
Function BTicks(sExecF, sLogF, sCmd )
goWSH.CurrentDirectory = sExecF
Dim aRet : aRet = Array(-1, "", "", "")
Dim sFSpec1 : sFSpec1 = goFS.BuildPath(sLogF, goFS.GetTempName() )
Dim sFSpec2 : sFSpec2 = goFS.BuildPath(sLogF, goFS.GetTempName() )
aRet(3) = Join(Array( _
qq("%comspec%") _
, "/c" _
, qq(Join(Array( _
sCmd _
, "1>" & qq(sFSpec1) _
, "2>" & qq(sFSpec2) _
)))))
Dim aErr
On Error Resume Next
aRet(0) = goWSH.Run(aRet( 3 ), SW_SHOWMINNOACTIVE, True)
aErr = Array(Err.Number, Err.Description, Err.Source)
On Error GoTo 0
If 0 <> aErr(0) Then
aRet(0) = aErr(0)
aRet(1) = Join(Array(aErr(1), aErr(2), "(BTicks)"), vbCrLf)
BTicks = aRet
Exit Function
End If
Dim nIdx : nIdx = 1
Dim sFSpec
For Each sFSpec In Array(sFSpec2, sFSpec1)
If goFS.FileExists(sFSpec) Then
Dim oFile : Set oFile = goFS.GetFile(sFSpec)
If 0 < oFile.Size Then
aRet(nIdx) = oFile.OpenAsTextStream(ForReading).ReadAll()
End If
oFile.Delete
End If
nIdx = nIdx + 1
Next
BTicks = aRet
End Function
由于必须包含此文件,因此不需要“旧”按钮 再过,javacompile.hta改为
<html>
<head>
<Title>JavaCompile</Title>
<hta:application id="javacompile" scroll = "no">
<script type="text/vbscript" src="javacompile.vbs"></script>
<script type="text/vbscript" src="util.vbs"></script>
</head>
<body>
<form>
<input type="button" id="bttBTicks" value="Use BTicks, Stupid"/>
<form>
</body>
</html>
和javacompile.vbs也变短了:
Option Explicit
Dim goFS : Set goFS = CreateObject("Scripting.FileSystemObject")
' document.location: "file:///E:/trials/SoTrials/answers/19944721/vbs/javacompile.hta"
Dim gsVbsF : gsVbsF = Replace(goFS.GetParentFolderName(Mid(document.location, 9)), "/", "\")
Dim gsJavaF : gsJavaF = goFS.GetAbsolutePathName(goFS.BuildPath(gsVbsF, "..\java"))
Dim gsGoodF : gsGoodF = goFS.BuildPath(gsJavaF, "good")
Dim gsBadF : gsBadF = goFS.BuildPath(gsJavaF, "bad")
Dim goWSH : Set goWSH = CreateObject( "WScript.Shell" )
Sub bttBTicks_onclick()
MsgBox "Sub bttUseBTicks_onclick() was called."
Dim aRet
aRet = BTicksCompile(gsGoodF, "javac Good.java")
aRet = BTicksCompile(gsGoodF, "bgood.bat")
aRet = BTicksCompile(gsBadF , "javac Bad.java")
aRet = BTicksCompile(gsBadF , "bbad.bat")
End Sub
Function BTicksCompile(sF, sCmd)
BTicksCompile = BTicks(sF, gsVbsF, sCmd)
MsgBox Join(BTicksCompile, vbCrLf & "--------" & vbCrLf)
End Function
现在没有更多的黑盒子,最后一个显示(对于bbad.bat)显示 神奇的单词FAILURE。
---------------------------
0
--------
Bad.java:4: reached end of file while parsing
}
^
1 error
--------
FAILURE

答案 1 :(得分:0)
你能指定绝对路径吗?
如果对true
使用objFSO.OpenTextFile
参数,那么如果找不到该文件,它将创建文件。我不明白为什么在你的情况下你会想要这样做,这可以解释你为什么不“阅读”文件。如果你刚刚在某个地方创建了它,它就会是空的。
如果您知道compile.bat
正在创建文本文件,则下一步是找出OpenTextFile
找不到它的原因。如果使用绝对路径,则可以快速解决此问题。
如果绝对路径不是一个选项,那么使用MsgBox WScript.ScriptFullName
或其他东西验证脚本运行的路径。
您可能也会这样做,这会使用脚本运行位置的相对路径
strPath = Replace(WScript.ScriptFullName,WScript.ScriptName,"")
objShell.Run ".\lib\Compile.bat" & " > " & strPath & "compile.txt", 0 ,True
Set objReadFile = objFSO.OpenTextFile(strPath & "compile.txt",1)
