File_Version is a Simple Tool developed in C#.Net. It will fetch you the Complete Dll and EXE information under any selected directory. Many a times, we may be required to know the information for Dlls\Exe's which gett installed with a particular product. This Tool will give you that information. It will fetch various parameters of Dll Ex:

Once we have this XML, we can write our own XSLT to convert it to any file format we want. I have written an XSLT, which will convert the output XML to an HTML page. Once it finds the information for entire DLL's or EXE's in a given directory, it gives output in an XML and HTML file. The other significant feature is build to build comparison of DLLs. Everytime it writes the output information to XML\HTML files with system date and time stamp. This will help us to store the information with date and time stamping . Thus, we can compare the previous and current found dll information.

Salient features of this tool:

1) It gives a simple UI to browse and select any particular folder.

2) It recursively searches entire directories or nested directories for every file

3) Gives complete DLL\EXE information in an XML format

4) XSLT available and can be modified easily as per the need to convert it to an HTML file format

5) Uses current system date and time for output file naming convention. Thus can store multiple files as repository for comparisons.

6) You can select any output path you wanted to store the files

7) Source code is written in C#.Net. You can alter the code if you want. It is attached in the folder


.Net Framework 2.0 need to be installed

How to Use:

1) Copy the dllhtml.xsl file(available in the attached ZIP) in your C: drive

2) Open the folder and click on "File_Version.EXE" file

3) It will then open the UI like this, Click on "Browse" Button to select the directory for search

4) Select the output directory where you wanted the output files to be placed

5) Click on the "Click" Button.

6) It will then two output files. One "<Systemdatedate>_dll_exe.xml" and "<Systemdatedate>_dll_exe.Html"

Once exported to outfiles, it opens the output html file as attached in the source code zip

Ok, below is the source code:

I need to modify the solution file removing my project specific information for some windows. I will attach the C# solution once Iam done with it in a day or two.
