FIX: MSHFlexGrid Dashes/Dots Invalid for GridLinesHeader/Indent

• Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 6.0

SYMPTOMS

When using the Hierarchical FlexGrid control it is possible to specify a specific type of line style (dots, dashes, etc.) that the control will use as a border between cells. These line style attributes can be set using the GridLinesHeader and GridLinesIndent properties of the control.

In versions of Visual Basic prior to Visual Studio Service Pack 3, when setting these two properties to either flexGridDashes(4) or flexGridDots(5) you may not see the appropriate line styles drawn in the MSHFlexGrid control. Instead the lines will be drawn as normal lines without using the correct style attribute.

RESOLUTION

This problem with the Microsoft Hierarchical FlexGrid has been fixed. See the STATUS section below for more information.

STATUS

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

This bug was corrected in Visual Studio 6.0 Service Pack 3. For more information about Visual Studio service packs, please see the following articles in the Microsoft Knowledge Base:

MORE INFORMATION

The code below reproduces this problem. This code uses the Northwind database (nwind.mdb) that ships with Visual Basic 6.0. You may need to change the connection string to point to your copy of the Northwind database.

1. Create a new Visual Basic 6.0 Standard EXE project and add a reference to the Microsoft ActiveX Data Objects library.



2. From the Project menu, choose Components and add a reference to the Microsoft Hierarchical FlexGrid Control 6.0.



3. Add an Hierarchical FlexGrid and a CommandButton to the default form.



4. Paste the following code into the form:




Const CONNECTSTR = "Provider=MSDataShape;Data Provider=Microsoft.Jet.OLEDB.3.51;" & _
                    "Persist Security Info=False;Data Source=" & _
                    "c:\Nwind.mdb"

Private Sub Command1_Click()
       
       MSHFlexGrid1.BandDisplay = flexBandDisplayVertical
       MSHFlexGrid1.BandIndent(1) = 2
       MSHFlexGrid1.ColHeader(1) = flexColHeaderOn
    
       MSHFlexGrid1.GridColorHeader(1) = QBColor(13)  '13 = light magenta (magenta = 5)
       MSHFlexGrid1.GridColorIndent(1) = QBColor(14)  '14 = light yellow (yellow = 6)

       MSHFlexGrid1.GridLinesHeader(1) = flexGridDashes
       MSHFlexGrid1.GridLinesIndent(1) = flexGridDashes
       
End Sub

Private Sub Form_Load()
       
       Dim cn As New ADODB.Connection
       Dim rs As New ADODB.Recordset
    
       cn.Open CONNECTSTR
       rs.Open "SHAPE {SELECT OrderID,CustomerID,ShipName FROM Orders} AS Command1 " & _
                "APPEND ({SELECT * FROM [Order Details]} AS Command2 " & _
                "RELATE 'OrderID' TO 'OrderID')", cn
    
       Set MSHFlexGrid1.DataSource = rs

End Sub
 

5. Run the code and note the bordering lines between the cells.
