Change default program a file extension opens with

[magace420]

Hello I created a simple program to print labels with a Dymo Label Creator.  However there is one part I cant seem to figure out how to automate.  the labels are saved like this file1.label, I need to change all .label extensions to open with a file in the script folder named printlabel.exe 

 

I have been doing it manually by right clicking the .label file, going to properties, and changing the opens with settings.  Is there any simple command I can run to change them automatically without having to right click and go into the properties?

This is what I want to automate>

Hope my request is easy to understand.   Thanks!!

Do you have something else that reads these .Label items why not Right click on one Choose - OPEN WITH select the checkmark next to always use selected application and choose your new default program?

Well i only have to change it once, but I'm going to give it to a few others to use and this would be one less thing to explain if i can get the script to do it.

Rather than restarting after you change your associations you should be able to call this function

#include <APIShellExConstants.au3>
#include <MsgBoxConstants.au3>
#include <WinAPIShellEx.au3>

    _WinAPI_ShellChangeNotify($SHCNE_ASSOCCHANGED, SHCNF_IDLIST)

File extension details are maintained in the registry, under HKEY_CLASSES_ROOT. If you do a search of the forum you will find where this has been done.
