Question

VB怎么让Form1、Form2并列选择？

如图，假设计算机、硬件、高级为各自的Form

Answer 1

VB里面有单独的选项卡控件， 按照下面就可以调出来。

Answer 2

Option Explicit
Private Declare Function SetParent Lib "user32.dll" ( _
ByVal hWndChild As Long, _
ByVal hWndNewParent As Long) As Long

Private Sub Command1_Click()
Form2.Visible = True
Form3.Visible = False
End Sub

Private Sub Command2_Click()
Form2.Visible = False
Form3.Visible = True

End Sub

Private Sub Form_Load()
Me.Move 0, 0, 12000, 12000
Form2.Show
Form3.Show
SetParent Form2.hWnd, Form1.hWnd
SetParent Form3.hWnd, Form1.hWnd

Form2.Move 500, 500, 5000, 5000
Form3.Move 500, 500, 5000, 5000
Form2.Visible = True
Form3.Visible = False
End Sub

Private Sub Form_Unload(Cancel As Integer)
End
End Sub
建议使用选项卡sstab来完成任务，细节百度vb sstab
