test fatto! SPETTACOLARE!!!!

Per rendere più simpatico il progetto, invece della label che fa da tooltip, si può fare con un Ballon Multiline?
io uso una classe ma per le listview... (https://www.freevbcode.com/ShowCode.asp?ID=571)

Re: TOOLTIP con mousemove

Tutto si può fare, ma ricorda che stai usando VB6, è da molto che non lo uso, le soluzioni semplici che mi vengono in mente sono per VB.Net, in VB6 ricordo che usavo i Form ritagliati, ma ora non mi torna in mente come.
Se sei alle prime armi e devi imparare, meglio usare il tempo con VB.Net.
VB6 ancora esiste per quei progetti non migrabili, che devono ancora essere mantenuti in funzione, se stai imparando meglio imparare in un linguaggio che ha molte più possibilità, cose difficili da fare in VB6 sono semplici in VB.Net o C#.
EDIT: ho ritrovato uno spezzone di codice VB6 messo da parte, al form devi aggiungere 8 pulsanti che cambieranno la dimensione del ritaglio.


Option Explicit
Dim a As Long
Dim b As Long
Dim c As Long
Dim d As Long


Private Declare Function CreateEllipticRgn Lib "gdi32" _
(ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, _
ByVal Y2 As Long) As Long

Private Declare Function SetWindowRgn Lib "user32" _
(ByVal hWnd As Long, ByVal hRgn As Long, _
ByVal bRedraw As Boolean) As Long

Private Sub Command1_Click()
a = a + 1
Command1.Caption = CStr(a)
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

Private Sub Command2_Click()
b = b + 1
Command2.Caption = CStr(b)
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

Private Sub Command3_Click()
c = c + 1
Command3.Caption = CStr(c)
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

Private Sub Command4_Click()
d = d + 1
Command4.Caption = CStr(d)
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

Private Sub Command5_Click()
a = a - 1
Command1.Caption = CStr(a)
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

Private Sub Command6_Click()
b = b - 1
Command2.Caption = CStr(b)
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

Private Sub Command7_Click()
c = c - 1
Command3.Caption = CStr(c)
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

Private Sub Command8_Click()
d = d - 1
Command4.Caption = CStr(d)
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

Private Sub Form_Load()
a = -59
b = -59
c = 441
d = 346
'Show The form!
SetWindowRgn hWnd, CreateEllipticRgn(a, b, c, d), True
End Sub

In VB.Net c'e il TrasparenceKey, basta colorare l'area del form che si vuole trasparente con il colore scelto nel TrasparenceKey e risolvi con una riga di codice.

Peccato, sarebbe stato bello.
In ogni caso se ti dovesse venire in mente qualcosa.....
Grazie sempre per la tua disponibilità.
