Methods to accept the return results of other scripting languages such as VBS in batch files!

First, give an example citing the example of user youxi01:

Look at the following code:

@echo off
:: Write a VBS file to find the length of a string
echo temp=wscript.arguments(0) >temp.vbe
echo for i=1 to len(temp) >>temp.vbe
echo if asc(mid(temp,i,1))^<0 then >>temp.vbe
echo strlen=strlen+2 >>temp.vbe
echo else >>temp.vbe
echo strlen=strlen+1 >>temp.vbe
echo end if >>temp.vbe
echo next >>temp.vbe
echo wscript.echo strlen >>temp.vbe
:Start
set /p EN=Please enter a string: (Press Enter directly to exit)=
if not defined EN goto :Over
:: Get the execution result of the VBE file
for /f %%i in ('cscript.exe temp.vbe %EN% //nologo') do echo.&echo The length of the string is: %%i
set EN=
goto :Start
:Over
:: Delete the generated file
del temp.vbe

This sentence is the key:
for /f %%i in ('cscript.exe temp.vbe %EN% //nologo') do ......
Using a for loop to read the VBS return result can also be regarded as a solution for batch processing to receive the return result of a script language. (Of course, in this program, it is not necessary to use for necessarily)

1. Temporary files
2. Parameters
3. Variables
4. Output redirection

Experts, please give a few examples and explain them.

The meaning of electronixtar is to first use a VBS script or other programs to write the returned results to a file, and then use batch processing to read the file.

Oh, I understand. The method of using `for /f %%i in ('C:\bea\weblogic91\common\bin\wlst.cmd startserver.py %status% //Nologo') do echo %%i` doesn't work.

electronixtar
Can you please give an example of a VBS script that writes the return result to a file and then uses a batch file to read the file?
Thank you!

This ~~ I'll write one
a.vbs
CreateObject("Scripting.FileSystemObject").CreateTextFile("test.txt").write "hello"
b.bat
for /f %a in ("test.txt") do @echo %a

Actually, my batch processing is really bad~

I'm now using
for /f %%i in ('C:\bea\weblogic91\common\bin\wlst.cmd startserver.py %status% //Nologo') do echo %%i
I want to get the value of the variable status in the startserver.py file
Why can't I get it out? I'm going crazy

Can the batch be divided into two parts? The first part calls vbs to generate parameters, and then let vbs call the second part of the batch with parameters. Is this possible?

What is the use of the part with %status% //Nologo in the parentheses of the line for /f %%i in ('C:\bea\weblogic91\common\bin\wlst.cmd startserver.py %status% //Nologo') do echo %%i?

How to return results when calling an SQL script in batch processing? For example, to get the installation directory of SQL Server, how to get it in batch processing? It's very simple with the SQL command, but I don't know how to pass the obtained string back to DOS.

Why can't I get it...

) What does C:\bea\weblogic91\common\bin\wlst.cmd startserver.py　%status% output?

) Does %status% have this variable? What is the content?

) //Nologo is a parameter for wscript.exe: does not display the logo, does not display the logo when executing,
　　　　　　　Is this related to your wlst.cmd startserver.py　%status%?

When I output startserver.py, it shows:
There is no label in the drive
The serial number of the volume is 9c83-6df1

Is it true that files that can't be listed by dir can't be found?

for /f "delims=" %%i in ('C:\bea\weblogic91\common\bin\wlst.cmd startserver.py') do echo %%i

Try again, what is output?

As long as the output information of your c:\bea\weblogic91\common\bin\wlst.cmd startserver.py is normal,
and there are no factors in the wlst.cmd code that cause the main batch processing of for /f .... to encounter不可抗力 (such as war, earthquake, ... ~: P).

What text information is output by your C:\bea\weblogic91\common\bin\wlst.cmd startserver.py, and what you retrieve with for is what (except for special cases).
