Anyway to use the Colour Dialog Selector with out a control?

Yes

VB Code:

Private Type CHOOSECOLOR
    lStructSize As Long
    hwndOwner As Long
    hInstance As Long
    rgbResult As Long
    lpCustColors As String
    flags As Long
    lCustData As Long
    lpfnHook As Long
    lpTemplateName As String
End Type
Private Declare Function CHOOSECOLOR Lib "comdlg32.dll" Alias "ChooseColorA" (pChoosecolor As CHOOSECOLOR) As Long
Private Function ShowColor() As Long
    Dim cc As CHOOSECOLOR
    Dim Custcolor(16) As Long
    Dim lReturn As Long
 
    'set the structure size
    cc.lStructSize = Len(cc)
    'Set the owner
    cc.hwndOwner = Me.hWnd
    'set the application's instance
    cc.hInstance = App.hInstance
    'set the custom colors (converted to Unicode)
    cc.lpCustColors = StrConv(CustomColors, vbUnicode)
    'no extra flags
    cc.flags = 0
 
    'Show the 'Select Color'-dialog
    If CHOOSECOLOR(cc) <> 0 Then
        ShowColor = cc.rgbResult
        CustomColors = StrConv(cc.lpCustColors, vbFromUnicode)
    Else
        ShowColor = -1
    End If
End Function
 
Private Sub Command1_Click()
 
Dim NewColor As Long
    
NewColor = ShowColor
 
If NewColor <> -1 Then
    Me.BackColor = NewColor
Else
    MsgBox "You chose cancel"
End If
 
End Sub

This code generating me an error. Can anybody help?

What error is it generating and on what line?

He forgot to include something. Add the following lines to the ShowColor Function

VB Code:

Dim CustomColors() As Byte
    ReDim CustomColors(0 To 16 * 4 - 1) As Byte

It writes me: "Invalid use of Me keyword". I am using visual basic editor 6.3. The "Me" is used in .Net?

I also do not understand what should this macro do.

Make sure all the code is in the form and not a module.

I have created an userform and commandbutton. The code is inside this userform. Now writes me an error: "Method or data member not found" at the line:
cc.hwndOwner = Me.hwnd

I have tryed to write me. again, but VB is not offering me hwnd.

If your form is called "Form1" then try Form1.hWnd

I have changed:
cc.hwndOwner = Useform1.Hwnd

to

cc.hwndOwner = Application.Hwnd

and

cc.hInstance = App.hInstance

to

cc.hInstance = Application.hInstance

Now it works. When I click commandbutton a color definition form is opened.
My intention was to place the rainbow rectangle (I do not know the official name) inside my own userform.

Can anybody help.

Are you attempting to do this in VB6 or VBA?

Please red my last quote. I would like to make an add-ins in Excel and I am using Visual Basic Editor, version 6.3.

When you say "Visual Basic Editor" it's a bit ambigious. The actual language you are using is VBA and it is not the same as VB6 the desktop production language. VBA has more limitations, one of which you have probably just found.

I do not dispute with you. I am not very experienced in VB. I have started to use it approximately a year before.
