I am showing some data in a DataGridView using an access table. Here is my

I have a date field in my Access database that I want to display in a textbox with a colored back color. This is VB.NET 2008. A datetimepicker has a format property (short) but the datetimepicker does not allow the color I want. No problem, it's just for display so I'll use a textbox. But the textbox shows the date and time. How can I get rid of the time in the textbox and just have the date? The field in the Access table is Date/Time with a format of Short. I think Access always stores the time.

View 10 RepliesI'm writing a simple program to retrieve data via the Serial Port. I have a piece of hardware that returns its 14 byte status every time vbCr is written to it.
