View 1 RepliesIm trying to use DateTimePicker function and save the date to an access database. Everything is working somewhat how I want it to but not 100% yet. Here is my problem. When the program is running if I click on the datetimepicker and select a date and click my save button the date IS saved to my access database as it should.
but if i run the program and don't ever click on the datetimepicker (because it is already on the correct current date) and click my save button the date doesn't get saved to the access database. The closest I have gotten was to enable the ShowCheckBox option, If i run the program this way and select the check box but dont select a date then it will save the date to my db.
But I really need it to be able to save the date to the db without the user ever clicking on the datetimepicker. Is it just a simple line I'm missing? Im pretty new to this but Ill try to explain anything the best I can if you have any further questions for me.
