Please download the attached MS Access database and perform the following.
1. Open the Item form, and observe the slider control in the sub form
2. When the slider is adjusted, please set 'TestValue' to the range between 'Minimum' and 'Maximum', assign to the slider's tool tip.
3. If the parent form's 'AutoUpdate' is checked while the 'TestValue' field has changed by slider or typing, please save the new value to a file in the form's 'AutoUpdateFolder' text value directory. Use CSV or XML with the ItemID, ValueName and Value. Overwrite if it exists.
3. When 'Store Value' is clicked, assign 'TestValue' to the 'DefaultValue', only when this button is clicked.
About 20 minutes work. Many thanks.
