Question

On Snow Leopard the third party services are disabled by default. Is there any way to enable it programmatically? I tried with NSRequiredContext and also by editing pbs.plist programmatically as given in following post

I had some trouble getting this to work in my application as well. When debugging this try calling NSUpdateDynamicServices() when your app launches and make sure you are registering a service provider. The problem could be that your service isn’t getting registered at all. You can use terminal to see which services are registered with /System/Library/CoreServices/pbs -dump_pboard

Example service:

<key>NSServices</key>
    <array>
        <dict>
            <key>NSMenuItem</key>
            <dict>
                <key>default</key>
                <string>Open with app</string>
            </dict>
            <key>NSMessage</key>
            <string>processService</string>
            <key>NSPortName</key>
            <string>MyApp</string>
            <key>NSRequiredContext</key>
            <array>
            </array>
            <key>NSSendTypes</key>
            <array>
                <string>NSStringPboardType</string>
                <string>NSRTFPBoardType</string>
                <string>NSURLPBoardType</string>
            </array>
        </dict>
    </array>
