Alguém sabe como alterar a Cor de Fundo/Fonte de um TooltipText???
Sei que é pelo Painel de Controle do Windows(Vídeo),
mas tenho muitas máquinas e gostaria de fazer pelo aplicativo em VB.
 
Grato,

Pra usar
label aceita icone
Set TT = New CTooltip

Set tt1 = New CTooltip
TT.Style = TTStandard
 
botão tem handle proprio
If Not m_blnButton Then
    m_blnButton = True
    tt1.Title = "Teste Mudança de Cor"
    tt1.TipText = "Command1"
    tt1.Create Me.Command1.hwnd
    tt1.BackColor = vbGreen
End If
no caso do label passe o handle do forma me.Hwnd
