Answer 1

Dim x1 As Integer, y1 As Integer
Dim x2 As Integer, y2 As Integer
Dim Tool As Integer

Private Sub Ellispe(ByVal x1 As Integer, ByVal y1 As Integer, ByVal x2 As Integer, ByVal y2 As Integer)
Dim t As Integer
Dim r As Single, rx As Single, ry As Single
If x1 > x2 Then
t = x1
x1 = x2
End If
If y1 > y2 Then
t = y1
y1 = y2
y2 = t
End If
rx = (x2 - x1 + 1) / 2
ry = (y2 - y1 + 1) / 2
If rx > ry Then r = rx Else r = ry
PicDraw.Circle (x1 + rx, y1 + ry), r, , , , ry / rx
End Sub

Private Sub Draw(ByVal x1 As Integer, ByVal y1 As Integer, ByVal x2 As Integer, ByVal y2 As Integer)
Select Case Tool
Case 1
PicDraw.Line (x1, y1)-(x2, y2)
Case 2
PicDraw.Line (x1, y1)-(x2, y2), , B
Case 3
Ellispe x1, y1, x2, y2
End Select
End Sub

Private Sub optTool_Click(Index As Integer)
Tool = Index
End Sub

Private Sub picDraw_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 1 Then
If Tool <> 0 Then
PicDraw.DrawMode = 6
Draw X, Y, X, Y
x1 = X
x2 = X
y1 = Y
y2 = Y
Else
PicDraw.PSet (X, Y)
End If
End If
End Sub

End If
End If
End Sub

Private Sub CmdEnd_Click()
End

注意一下你的變數定義 Integer,其中第一個英文字母是 I 不是 L ,你在程式裡面都打L ( l ) !!
另外最下面多了一個 End sub 把它砍了!!
你的離開沒有功能我幫你加上去嚕^^!!!

Answer 2

恩....小弟只能深深的佩服你....字可以全部都打錯...是看者書打嗎...?
不是lnteger 是integer 是 i I 喔，不是L

還有最後面多了一個end sub
這樣應該就可以了
