Listview Column ReOrder

I have several listviews in my VB6 application that are filled with data from an Access database. I have the "AllowColumnHeaderReorder" value set to true. This allows me to change the arrangement/order of the Columns and display the information, but it does not save this order for future views. Each time a new set of data is displayed, I have to rearrange the columns again.

Is there sample source code available that would allow a user to select what columns are displayed, in a listview, and in what order, and have those selections saved to an ini file, or someplace else?

The VB6 "Reference Listview" is an example of what I'd like to use to set these display settings. Then when the listview loads the data, it will be in the correct order.

Thank you in advance. :afrog:

Save some indication of the order in the Registry, a file, or a database.

In addition, have a look at the ColumnHeader.Position and
ColumnHeader.SubItemIndex properties

Hi Mr. M.,

Thank you for you response. But I was hoping for a reply with some code I could use as a beginning. Like your link, "VB - Color a row in a ListView".

With some source to examine, that covers how the form functions that I included in the attached illustration, I might be able to work out a solution for my needs.

Thank you again.

Okay here is a modified version of my app that you referred to. You will need to add the Northwind.mdb

Thank you Marty. This gives me a starting point. I've already added the Northwind database and I think I understand the basics. :bigyello:

Hi Marty,

The information and code was a great start. I found an issue with the unload event, which is probably why you weren't happy with it. The code works fine the first time to save the re-ordered columns. But when you close the application the second time, the order reverts back to 123.

I know why this is happening, and I'm on the job of creating a solution. At least I have the basics to work with now. When I have something that works, I'll post it.

Private Sub Form_Unload(Cancel As Integer)

'NEW - Save the column order. (I'm not happy with this but it works.)
Dim strOrder As String
Dim intVal As Integer

intVal = 1
Do Until lvFind.ColumnHeaders(intVal).Position = 1
intVal = intVal + 1
Loop
strOrder = lvFind.ColumnHeaders(intVal).Index

intVal = 1
Do Until lvFind.ColumnHeaders(intVal).Position = 2
intVal = intVal + 1
Loop
strOrder = strOrder & lvFind.ColumnHeaders(intVal).Index

intVal = 1
Do Until lvFind.ColumnHeaders(intVal).Position = 3
intVal = intVal + 1
Loop
strOrder = strOrder & lvFind.ColumnHeaders(intVal).Index
SaveSetting "MyColumnPositionApp", "Column Positions", "MyListview", strOrder


Set frmFind = Nothing

End Sub

Okay I've got it.

Code:

---

Private Sub Form_Load()
   
    ' Create the instance of the database class
    Set gDB = New CDatabase
   
    ' Open the database
    gDB.dbName = App.Path & "\northwind.MDB"
   
   
  'NEW - Get saved order. If there are none (1st run) then the default order is 123
  mstrColumnPositions = GetSetting("MyColumnPositionApp", _
                        "Column Positions", "MyListview", "Product|Supplier ID|Category ID")
    mstrColumnPositions = Replace(mstrColumnPositions, " ", "_")
 
    Dim strParts() As String
    strParts = Split(mstrColumnPositions, "|")
   
    CallByName frmFind, strParts(0), VbMethod
    CallByName frmFind, strParts(1), VbMethod
    CallByName frmFind, strParts(2), VbMethod

  lvFind.BorderStyle = ccFixedSingle ' Set BorderStyle property.
  lvFind.View = lvwReport ' Set View property to Report.

  ' Label OptionButton controls with SortOrder options.
      OptSort(0).Caption = "Sort Ascending"
      OptSort(1).Caption = "Sort Descending"
      lvFind.SortOrder = lvwAscending ' Sort ascending.
      OptSort(0).Value = True

End Sub

---

Replace the Column1, etc subs with these.

Code:

---

Public Sub Product()
  Dim clmX As ColumnHeader
  Set clmX = lvFind.ColumnHeaders.Add(, , "Product", (lvFind.Width - 1066) / 2)

End Sub

Public Sub Supplier_ID()
  Dim clmX As ColumnHeader
  Set clmX = lvFind.ColumnHeaders.Add(, , "Supplier ID", (lvFind.Width - 1066) / 2)

End Sub

Public Sub Category_ID()
  Dim clmX As ColumnHeader
  Set clmX = lvFind.ColumnHeaders.Add(, , "Category ID", 976)

End Sub

---

Code:

---

Private Sub Form_Unload(Cancel As Integer)
   
    Dim strOrder As String
    Dim intVal As Integer
   
    SaveSetting "MyColumnPositionApp", "Column Positions", "MyListview", _
                lvFind.ColumnHeaders(lvFind.ColumnHeaders(1).Position).Text & "|" & _
                lvFind.ColumnHeaders(lvFind.ColumnHeaders(2).Position).Text & "|" & _
                lvFind.ColumnHeaders(lvFind.ColumnHeaders(3).Position).Text

             
    Set frmFind = Nothing
   
End Sub

BTW, your registry will contain 123 or some variation of that order and in my new scheme you use the column header text so you'll have to override what is there the first time after you make these above changes. Just in case you don't know how to do that

1. Put a breakpoint on the mstrColumnPositions = Replace(mstrColumnPositions, " ", "_") line
2. In the Immediate Window type mstrColumnPositions = "Product|Supplier ID|Category ID" and press return.
