Hi Don,

There is not a easy way to set a the color of a single Window's title bar. You only can set the system color setting by via the SetSysColors API. You can work around the issue in this way:

1. In the Activated event of the form store the Windows setting of the title bar and set it to your color
2. In the Deactivate event restore the Windows setting

There is a sample code of it:

Imports System.Runtime.InteropServices

<DllImport("user32.dll")> _
Private Shared Function GetSysColor(ByVal nIndex As Int32) As Int32
End Function

<DllImport("user32.dll")> _
Private Shared Function SetSysColors(ByVal cElements As Integer, ByVal lpaElements() As Int32, ByVal lpaRgbValues() As Int32) As [Boolean]
End Function

Private Const COLOR_ACTIVECAPTION As Integer = 2

Private oldColor As Integer

Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Activated
    oldColor = GetSysColor(COLOR_ACTIVECAPTION)

    Dim element() As Integer = {COLOR_ACTIVECAPTION}
    Dim rgb() As Integer = {Color.White.ToArgb() And &HFFFFFF}
    Dim b As Boolean = SetSysColors(1, element, rgb)
End Sub 'Form1_Activated

Private Sub Form1_Deactivate(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Deactivate
    Dim element() As Integer = {COLOR_ACTIVECAPTION}
    Dim rgb() As Integer = {oldColor}
    Dim b As Boolean = SetSysColors(1, element, rgb)
End Sub 'Form1_Deactivate
