As I suggested in my previous message, add a proprty ReturnValue to your form, assign return value to it in the Click of the control and than return it in Unload

* Click Event
Thisform.AddProperty("ReturnValue", thisform.oleCalendar.value ) 
...
* Unload
RETURN Tisform.ReturnValue

This format is used to reference the properties and methods of the Automation server. I don't know why it's requred for Calendar control in VFP 5.

>>You have to use Unload event return statement to return value from modal form. You can save return value to the form's property in cmdSelect.click and use later in Unload.
