Enumerating Binary Resource Languages

The small application is a goos sample and useful tool in the same time. It enumerates PE binary resources and counts languages used. Why? Normally you want single language of resources, however Visual Studio IDE does not show you languages in a convenient way and it is so easy to make a language mess which does not bite you immediately but might bring you troubles later. Apart from this there was a suspicion that language mess might cause runtime bugs on UpdateResource API.

The application gets you a summary of languages used and returns with exit code (checkable using e.g. errorlevel) indicating number of languages.

Output is TSV: LANGID, Language Name, Resource Count:

C:\>ListResourceLanguages.exe C:\Windows\syswow64\shell32.dll
1049    Russian 545
1033    English 3318

Resource Tools: Custom Resource Types

This update for Resource Tools adds an option to access custom resource types, such as FILE, TYPELIB, REGISTRY etc. It lets enumerate the resource, and load/save them. The COM interafce adds new Items property; the code snippet below accesses type library of image2.dll and saves it into external tyle library file image2.tlb:

image = new ActiveXObject("AlaxInfo.ResourceTools.Image");
image.Items("TYPELIB").Item(1).SaveToFile(null, "imapi2.tlb");

Additionally, image.EndUpdate(false) call makes the object close all references to the underlying file so that it can be available for other operations (e.g. overwrite), and the COM object might be further re-initialized and reused.

Resource Tools: 64-bit build

I rebuilt the Resource Tools utility in 64-bits to, supposedly, be able to be good with resources on 64-bit binaries (actually 32-bit code might be dealing with those fine also?). Anyway, the build is here and the tool available in both 32-bit and 64-bit versions.

In particular, both 32-bit and 64-bit JavaScript scripts hosted by Windows Scripting Host (respectively, 32-bit from C:\Windows\syswow64 or 64-bit from C:\Windows\system32 – in 64-bit Windows) can leverage the tool in file manipulation.

This utility is specifically helpful in automating steps which involve resource updates, such as to apply OEM branding, or resource-based file operations. The code snippet below archives a copy of DLL and PDB files for published release into a .7z archive named using current file version of the DLL itself (that is, it created a ResourceTools.dll- archive file out of ResourceTools.dll and corresponding ResourceTools.pdb files):

image = new ActiveXObject("AlaxInfo.ResourceTools.Image");
image.Initialize(inputDirectory + fileName);
productVersion = image.VersionInfo.ProductVersionString;
fileVersion = image.VersionInfo.FileVersionString;
WScript.Echo(" Product Version: " + productVersion);
WScript.Echo(" File Version: " + fileVersion);
shell = WScript.CreateObject("WScript.Shell");
currentDirectory = shell.CurrentDirectory;
shell.CurrentDirectory = currentDirectory + "\\" + inputDirectory;
try {
    shellExec = shell.Exec(
        "\"" + toolDirectory + "7z" + "\" " +
        "a -t7z " +
        "\"" + currentDirectory + "\\" + outputDirectory + "ResourceTools.dll-" + fileVersion + ".7z" + "\" " +
        "ResourceTools.dll" + " " +
        "ResourceTools.pdb" + " " +
    while (shellExec.Status == 0)
    if (shellExec.ExitCode != 0)
        throw new Error("7-Zip Exec failed, .ExitCode " + shellExec.ExitCode.toString());
    WScript.Echo(" Output File: " + "ResourceTools-" + fileVersion + ".7z");
finally {
    shell.CurrentDirectory = currentDirectory;
