FIX: ListBox Sorted Property Does Not Sort

• Microsoft Windows CE Toolkit for Visual Basic 5.0, version 1.0

SYMPTOMS

When a ListBox Sorted property is set to True, the items in the ListBox are not sorted.

RESOLUTION

This bug requires a sort routine to be implemented manually if the ListBox items need to be sorted. The following is a sample of how this might be accomplished.

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



2. Place a ListBox (List1), a TextBox (Text1) and a CommandButton (Command1) on Form1.



3. Paste the following code into the General Declarations section of Form1:

   
         Dim strArray()
   
         Private Sub Form_Load()
             'initialize the array
             ReDim strArray(0)
   
             AddItem strArray, "Utah"
             AddItem strArray, "Washington"
             AddItem strArray, "Virginia"
             AddItem strArray, "Iowa"
             AddItem strArray, "Oregon"
             AddItem strArray, "Alabama"
             AddItem strArray, "Mississippi"
             AddItem strArray, "Ohio"
   
             Sort strArray, List1
         End Sub
   
         Private Sub Command1_Click()
             If Text1.Text <>  "" Then
                 AddItem strArray, Text1.Text
                 Sort strArray, List1
             End If
         End Sub
   
         Sub AddItem(inpArray(), inpItem)
             ReDim Preserve inpArray(UBound(inpArray) + 1)
             inpArray(UBound(inpArray)) = inpItem
         End Sub
   
         Sub Sort(inpArray(), inpList)
             Dim intRet
             Dim intCompare
             Dim intLoopTimes
             Dim strTemp
   
             For intLoopTimes = 1 To UBound(inpArray)
                 For intCompare = LBound(inpArray) To UBound(inpArray) - 1
                     intRet = StrComp(inpArray(intCompare), _
                              inpArray(intCompare + 1), vbTextCompare)
   
                     If intRet = 1 Then 'String1 is greater than String2
                         strTemp = inpArray(intCompare)
                         inpArray(intCompare) = inpArray(intCompare + 1)
                         inpArray(intCompare + 1) = strTemp
                     End If
                 Next
             Next
   
             'clear the list and repopulate.
             inpList.Clear
             For intCompare = 1 To UBound(inpArray)
                 inpList.AddItem inpArray(intCompare)
             Next
         End Sub 




4. Press the F5 key to run the Project.



5. Type some text into Text1.



6. Click Command1 to add the item into the ListBox, and note that the new item is in the proper sort order.

STATUS

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

This problem was corrected in Windows CE Toolkit for Visual Basic 6.0.

MORE INFORMATION

Steps to Reproduce Behavior

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



2. Place a ListBox (List1), a TextBox (Text1) and a CommandButton (Command1) on Form1.



3. Set the Sorted property of List1 to True.



4. Paste the following code into the General Declarations section of Form1:

   
         Option Explicit
   
         Private Sub Command1_Click()
              List1.AddItem Text1.Text
         End Sub
   
         Private Sub Form_Load()
              Command1.Caption = "Add Text To List Box"
              Text1.Text = ""
              List1.Clear
         End Sub 




5. Press the F5 key to run the project.



6. Type "Washington" in Text1 and click Command1.



7. Type "Alaska" in Text1 and click Command1.
