[RESOLVED] creating custom colors before opening the commondialog box

Hai,

I've been looking around a bit but couldn't find anything about this.

I want to create/build some custom colors (programmaticly) before the commondialog box is opened.

the objective is to let the user choose either one of the standard colors or 1 of the 6 colors used in their logo.

Is it possible and how to approach this?

Thanks in Advance

Here's an API solution that doesn't require the Common Dialog Control.

VB Code:

Private Declare Function ChooseColorAPI _
 Lib "comdlg32.dll" Alias "ChooseColorA" ( _
 pChoosecolor As CHOOSECOLOR) As Long
 
Private Type CHOOSECOLOR
    lStructSize As Long
    hwndOwner As Long
    hInstance As Long
    rgbResult As Long
    lpCustColors As Long
    flags As Long
    lCustData As Long
    lpfnHook As Long
    lpTemplateName As String
End Type
 
Public Function ShowColor() As Long
    Dim cc As CHOOSECOLOR
    Dim lReturn As Long
    Dim CustomColors(15) As Long
    Dim i As Integer
    
    'Set the custom colors in the CustomColors array
    CustomColors(0) = vbRed
    CustomColors(1) = vbGreen
    CustomColors(2) = vbYellow
    'and so on
    
    cc.lStructSize = Len(cc)
    cc.hwndOwner = Me.hWnd
    cc.hInstance = 0
    cc.lpCustColors = VarPtr(CustomColors(0))
    cc.flags = 0
    lReturn = ChooseColorAPI(cc)
    If lReturn <> 0 Then
        ShowColor = cc.rgbResult
    Else
        'User clicked the Cancel button so we return -1 instead of a color
        ShowColor = -1
    End If
End Function

Thanks I will play around with it

I am preparing my own color definition routine (maybe add-ins). I have only Visual Basic Editor - Version 6.3. This code writes me an error. How I should change

VB Code:

Me.

part of the code? I do not understand what this code should do.
