File association - automaticly open file type on doubleclick

[2xD]

Hey,

I have different project files with the extension .qmap and want these files to automaticly open in my app on doubleclick. I used the yaso object and actually these files do open successfully in the app, but only after I manually selected my app via "open with" and searched the app path. Is there any way the files will automaticly be associated after first app run, so doubleclick on project files will work after that?

FileAssociation.zip

Also, why the app has no title in explorer??

Thanks!

Mr. A made file association easy in Multimedia Fusion 2. I imagine it probably still works with Fusion, but I haven't tested.

Hmm, nothing of these works for Win 7 and higher, for me at least..

I used a workaround with registry: http://stackoverflow.com/questions/9...n-in-windows-7

Works fine, tested in XP, Vista, 7, 8, 8.1, 10.

Via registry:

Right click HKEY_CLASSES_ROOT and pick New, Key. Name it according to your desired file extension, e.g. .ext. If it exists already, you can skip this step.
Set the default value of the key you just created to some unique name that isn't used yet, e.g. MyFileType. Again, if it's set already, skip this step.
Create another new key using the same name you picked in the previous step. Skip this too, if the key exists already.
Set the default value of the new key to the name that should appear in Windows Explorer and other programs as the file type.
Right click the new key and create a subkey DefaultIcon.
Set the new key's default value to C:\Some\Path\To\Your\Icon\Ressource.ico,0 (the 0 is the index of the icon to be used; if there's only one icon in the ressource, it has to be 0).
Create another new key next to DefaultIcon and call it shell.
Now, for each verb/action you'd like to associate, create a new sub key with the desired name. Some verbs are preset and will automatically use localized names, e.g. open, edit or print.
For each verb create a sub key command and set its default value to the program to be run. Also make sure to include all parameters needed, adding quotes if there are spaces inside, e.g. "C:\My Path\My Program.exe" "%1". %1 will be replaced with the actual file name picked for this action.
