PRB: ComboBox Text Property Does Not Update Properly

• Windows CE Toolkit for Visual Basic 5.0, version 1.0

SYMPTOMS

The ComboBox Text property is not updated until after the ComboBox Click event is complete. This behavior may be a problem if the value of the Text property is required during the ComboBox Click event.

RESOLUTION

The ListIndex property is updated as soon as the item is selected and can be used to determine the text of that item. To work around this problem, use the ListIndex property as follows:

   Combo1.List(Combo1.ListIndex)

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

1. Start a new Windows CE Project in Visual Basic 5.0. Form1 is created by default.

2. Add a ComboBox (Combo1) to Form1.

3. Add the following code:

         Option Explicit
         Dim x
   

         Private Sub Form_Load()
            For x = 1 to 8
               Combo1.AddItem "Item" & x
            Next
         End Sub
      
         Private Sub Combo1_Click()
            MsgBox "Text: " & Combo1.Text & ", ListIndex: " & _
            Combo1.ListIndex
         End Sub
   
   

4. Press the F5 key to run the project.

5. Click the drop-down arrow of Combo1 and then select "Item1." Note that the message box shows the value of the Text property as "Combo1" instead of "Item1."
