sync dropbox with api

If I could do this I would ask you a question.

you can send me a sample preferably with vb6

I have the Dropbox application installed on my computer, it does this well

Like this

SetApplicationAttribute(android:label, "@string/app_name") ' NEW in v3.0!!!
AddApplicationText(
<activity android:name="com.dropbox.sync.android.DbxAuthActivity" />
<activity
  android:name="com.dropbox.client2.android.AuthActivity"
  android:launchMode="singleTask" >
  <intent-filter>
    <data android:scheme="db-YOURAPPKEY" /> <!-- NEED TO UPDATE -->
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.BROWSABLE" />
    <category android:name="android.intent.category.DEFAULT" />
  </intent-filter>
</activity>
<service
  android:name="com.dropbox.sync.android.DbxSyncService"
  android:enabled="true"
  android:exported="false"
  android:label="Dropbox Sync" />
  )
