用VB编写一个小程序

Dim a, b

Private Sub Command1_Click()

End

End Sub

Private Sub Form_Load()

Text.Text = "Visual Basic程序设计"唯仔冲

Command1.Caption = "指歼结束"

Text.Left = 0: Text.Top = 0: Text.Width = 0.5 * Form1.Width

Text.Height = 0.5 * Form1.Height

a = Form1.Width - Command1.Left

b = Form1.Height - Command1.Top

End Sub

Private Sub Form_Resize()

Text.Left = 0: Text.Top = 0: Text.Width = 0.5 * Form1.Width

Text.Height = 0.5 * Form1.Height

Command1.Left = Form1.Width - a

Command1.Top = Form1.Height - b

End Sub

注意，各变戚神量名，控件名保持一致,你题目中的文本框名称为text

Private Sub Command1_Click()

  Me.Cls

  Dim N As Integer, i As Integer

  N = InputBox("n=", , 袭李9)

  For i = 1 To 2 * N - 1

    If i <= N Then

      Print Space(N - i) + String(2 * i - 1, CStr(i))

    Else

      Print Space(N - (2 行禅裂* N - i)) + String(2 * (2 * N - i) - 1, CStr(2 * N 档闭- i))

    End If

  Next i

End Sub

Dim sec, min, h

Private Sub Command1_Click()

Timer1.Enabled = True

h = Text1.Text

min = Text2.Text

sec = Text3.Text

Timer2.Enabled = False

Command2.Caption = "腊册庆退出"

Command1.Caption = "开始倒计时"姿罩

End Sub

Private Sub Timer1_Timer()

If sec >0 Then
