MLSynchronization and MLSync objects
Specifies whether to display a progress window during synchronization.
At design time, you can select the Use Progress Window check box on the Logging tab of the Properties view for an MLSync object. You must also supply a progress window name or set the ProgressWindowName property if you want to display a progress window.
At runtime, application users can select the Display if Available radio button option on the Settings tab page of the default synchronization options window generated by the MobiLink wizard. Otherwise users can select the Do Not Display radio button option to prevent a progress window from displaying.
You can change the UseWindow value in script as follows:
mySync_1.UseWindow = true
