Get RGB value of all shapes

Post by Stefan_Sand »

Hello,

is there a VBA function to get the RGB value of all named shapes in a worksheet?
In my example (taken the US Presidents election) i have a lot of named shapes, which can be colored by clicking them.
Is it possible to get out the value of the colors?

best regards in advance,
Stef

The following function returns an array of 4 numbers: R, G, B and color.

Code: Select all

Function GetRGB(s As String)
    Dim shp As Shape
    Dim r As Long
    Dim ret(1 To 4) As Long
    Application.Volatile
    Set shp = Application.Caller.Parent.Shapes(s)
    r = shp.Fill.ForeColor.RGB
    ret(4) = r
    ret(1) = r Mod 256
    r = r \ 256
    ret(2) = r Mod 256
    ret(3) = r \ 256
    GetRGB = ret
End Function
See the attached version.

Warning: as with all such functions, it does not update itself automatically when you click a shape. It will update whenever Excel recalculates.
Or to force Excel to do so, change the ChangeColor macro:

Code: Select all

Sub ChangeColor()
    With ActiveSheet.Shapes(Application.Caller).Fill.ForeColor
        Select Case .RGB
            Case RGB(217, 217, 217)
                .RGB = RGB(73, 104, 238)
            Case RGB(73, 104, 238)
               .RGB = RGB(250, 50, 50)
            Case RGB(250, 50, 50)
                .RGB = RGB(191, 191, 191)
            Case RGB(191, 191, 191)
                .RGB = RGB(217, 217, 217)
        End Select
    End With
    ' Recalculate formulas
    ActiveSheet.Calculate
End Sub

Hans
