SYMPTOMS

You have a DataTimePicker control's CustomFormat property set, but when you set the Format property to dtpCustom, the CustomFormat is not used.

RESOLUTION

When you set a DateTimePicker's Format property to dtpCustom, you must follow this by assigning the CustomFormat property, even if it already contains a valid format string. This assignment to CustomFormat may be a new string value or it may be assigned to itself.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

Steps to Reproduce Behavior

  1. In a new Standard EXE project. Form1 is created by default. From the Projects menu, select Components, check "Microsoft Windows Common Controls-2 6.0," and click OK.
  2. Add two CommandButtons and a DTPicker control to Form1.
  3. Enter a custom format into the DTPicker control's CustomFormat property. For this example, use 'Today is' MMM d, yyy.
  4. Add the following code to the Form's Module: 
          Private Sub Command1_Click()
         DTPicker1.Format = dtpCustom
      End Sub

      Private Sub Command2_Click()
         DTPicker1.Format = dtpCustom
         DTPicker1.CustomFormat = DTPicker1.CustomFormat
      End Sub
  5. Run the Project and Click Command1. Note that the CustomFormat is not used and the date is displayed as a short date.
