Hola,
Dessa proba este code:
Option Explicit
Private Type POINTAPI
x As Long
y As Long
End Type
Private Declare Function GetPixel Lib "gdi32" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long) As Long
Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
Private Declare Function GetWindowDC Lib "user32" (ByVal hwnd As Long) As Long
Private Sub Form_Load()
Timer1.Interval = 100
End Sub
Private Sub Timer1_Timer()
Dim tPOS As POINTAPI
Dim sTmp As String
Dim lColor As Long
Dim lDC As Long
lDC = GetWindowDC(0)
Call GetCursorPos(tPOS)
lColor = GetPixel(lDC, tPOS.x, tPOS.y)
Me.BackColor = lColor
sTmp = Right$("000000" & Hex(lColor), 6)
Me.Caption = "R:" & Right$(sTmp, 2) & " G:" & Mid$(sTmp, 3, 2) & " B:" & Left$(sTmp, 2)
End Sub
saludos.
