How write file as (image inside dll file) ?
imageres.dll,262

I haven't personally tried this, but the following should work:

• For replacing icons already present in imageres.dll, see Icons - Change Using Resource Hacker.
• For adding new icons to imageres.dll, see HOW TO...Add Icons to Windows System File ''imageres.dll''.

I'm need make custom imageres.dll librarry for my application only as appicons.dll not use imageres.dll

It's similar to the above-linked video, i.e.

1. Use the original imageres.dll file as the template by making a copy of it and renaming it to something like appicons.dll
2. Then delete the original icons and add the new ones you need and save the file.

Additional instruction resources: How to Make Your Own DLL File with Customized Icons, and another easier approach.

Thank you

Hello, i tryed your solution but i don't have admin rights on my work computer, so i put the entry in HKEY_CURRENT_USER\Software\Classes*\shell\MakeMD5\command, it appears all right in context menu but upon clicking I get the following error : "Windows Cannot Access the Specified Device Path or File"
But on the file i right click "MakeMD5" the rights are all good, it's a file i created myself. i really don't get the error.
I tried to add another entry : HKEY_CURRENT_USER\Software\Classes*\shell\Npp++\command, with the value "C:\Program Files\Notepad++\notepad++.exe" "%1", and it's working perfectly
If someone can spare any help?

In Computer\HKEY_CURRENT_USER\Software\Classes\*\shell\MakeMD5\Command, I added the following value:
cmd /s /c pushd &(call certUtil -hashfile "%1" MD5) > ""%1"-Hash (MD5)".txt

Tested this to be working for an admin account. First, try this one to make sure there weren't any simple typo mistakes.
