Who is stupid ??

Me, the Treeview control or the Windows API ?

I ran a brief search on changing the background colour of the Treeview control on the forum and got a small SendMessage API function call to do the job.

I pasted the declaration and the constants in my code and ran the application. The background colour did change, but it seems that there are just about 3 different colours it can take.

How do I set the backcolor of the TreeView control to be the one I have set for my textbox? Remember I set the colour of the TextBox control using the colour palette.

I tried changing the RGB function parameters, but all combinations seem to give me only two or three colours. Can someone please help me in setting the desired colour as the background colour of a TreeView control ?

VB Code:

Option Explicit
 
      Private Declare Function SendMessage Lib "User32" _
         Alias "SendMessageA" _
         (ByVal hWnd As Long, _
         ByVal wMsg As Long, _
         ByVal wParam As Long, _
         lParam As Long) As Long
 
      Private Declare Function GetWindowLong Lib "User32" _
         Alias "GetWindowLongA" _
         (ByVal hWnd As Long, _
         ByVal nIndex As Long) As Long
 
      Private Declare Function SetWindowLong Lib "User32" _
         Alias "SetWindowLongA" _
         (ByVal hWnd As Long, _
         ByVal nIndex As Long, _
         ByVal dwNewLong As Long) As Long
 
      Private Const GWL_STYLE = -16&
      Private Const TVM_SETBKCOLOR = 4381&
      Private Const TVM_GETBKCOLOR = 4383&
      Private Const TVS_HASLINES = 2&
 
      Dim frmlastForm As Form
 
      Private Sub Form_Load()
          Dim nodX As Node
          Set nodX = TreeView1.Nodes.Add(, , "R", "Root")
          Set nodX = TreeView1.Nodes.Add("R", tvwChild, "C1", "Child 1")
          Set nodX = TreeView1.Nodes.Add("R", tvwChild, "C2", "Child 2")
          Set nodX = TreeView1.Nodes.Add("R", tvwChild, "C3", "Child 3")
          Set nodX = TreeView1.Nodes.Add("R", tvwChild, "C4", "Child 4")
          nodX.EnsureVisible
          TreeView1.style = tvwTreelinesText ' Style 4.
          TreeView1.BorderStyle = vbFixedSingle
      End Sub
 
      Private Sub Command1_Click()
         Dim lngStyle As Long
 
         Call SendMessage(TreeView1.hWnd, _
                           TVM_SETBKCOLOR, _
                           0, _
                           ByVal RGB(255, 0, 0))  'Change the background
                                                  'color to red.
 
      ' Now reset the style so that the tree lines appear properly
         lngStyle = GetWindowLong(TreeView1.hWnd, GWL_STYLE)
         Call SetWindowLong(TreeView1.hWnd, _
                           GWL_STYLE, _
                           lngStyle - TVS_HASLINES)
         Call SetWindowLong(TreeView1.hWnd, GWL_STYLE, lngStyle)
      End Sub
