Are you expecting the batch file to query the file for its' version? What kind of file is it and how is the version number stored?

Zon-cpp 18-Apr-17 7:20am

It is a .dll file that was created by C# and it's version was defined in AssemblyInfo.cs

This would be hard to answer for anybody that has not seen your previous question How do I know the DLL version, in compile time?[^]

An example using the sigcheck utility from the SysInternals suite:

@ECHO off
REM Specify source directory of your project here
SET outputdir=c:\projects\myproject\
REM Execute sigcheck to print only file version and redirect to a temp file
path-to-sigcheck\sigcheck -n -q path-to-dll >%outputdir%temp.txt
REM Get file content into a variable
SET /p FILEVER=<%outputdir%temp.txt
REM Create header file
ECHO #pragma once > %outputdir%dll_ver.h
ECHO #define MY_DLL_VERSION _T("%FILEVER%") >> %outputdir%dll_ver.h
REM Uncomment to show the created file
REM type %outputdir%dll_ver.h

[EDIT]
Added the _T() macro to the string printed to the header file.

I want to get version of 'my file' in CustomBuildStep of my project and write it in a text file. then in about window show that text file as version of my file.

At first you need an utilty to get the version from a file.
I have used sigcheck in my example.
The example writes the output to a text file (temp.txt in my example).

It then creates a header file dllver.h. I have done that because it can be included in your source file (#include "dll_ver.h"). There you can use the MY_DLL_VERSION string to create the string to be shown in the dialog box.

Save the example file using a .bat extension and execute it as custom build step.
