五、倒计数器
Private Sub C1_Click(Index As Integer)
Select Case Index
Case 1
Timer1.Enabled = False
Case 0
Timer1.Enabled = True
End Select
End Sub
Private Sub Form_Load()
End Sub
Private Sub Timer1_Timer()
Text1.Text = Text1.Text + 1
End Sub |
六、文本框的使用
Private Sub C1_Click()
Open App.Path & "\out7.txt" For Output As #2
Print #2, Text1.Text
Close #2
End Sub
Private Sub Form_Load()
Open App.Path & "\in7.txt" For Input As #1
Do While Not EOF(1)
Input #1, mystring
Text1.Text = Text1.Text + mystring
Loop
Close #1
Text1.Text = "计算机等级考试" + Text1.Text
End Sub |
七、求某类数的和等：
Private Function fun(a As Integer) As Integer
s% = 0
For i% = 500 To 600
If Int(i% / a) = i% / a Then
s% = s% + i%
End If
Next
fun = s%
End Function
Private Sub C1_Click()
If Op1.Value Then
Text1 = fun(7)
End If
If Op2.Value Then Text1 = fun(3)
End Sub
Private Sub Form_Unload(Cancel As Integer)
Open "out7.txt" For Output As #1
Print #1, Op1.Value, Op2.Value, Text1.Text
Close #1
End Sub |
八、文本框的使用
Private Sub C1_Click()
Open App.Path & "\in7.txt" For Input As #1
Do While Not EOF(1)
Input #1, mystring
Text1.Text = mystring
Loop
Close #1
End Sub
Private Sub C2_Click()
Text1.Text = UCase(Text1.Text)
End Sub
Private Sub C3_Click()
Open App.Path & "\out7.txt" For Output As #2
Print #2, Text1.Text
Close #2
End Sub |
九、文本框应用第二例：
第一部分，窗体程序部分：
Dim a(100) As Integer
Private Sub Cmd1_Click()
Open App.Path & "\in.txt" For Input As #1
Text1.Text = ""
For i = 1 To 100
Input #1, a(i)
Text1.Text = Text1.Text & a(i) & Space(1)
Next i
Close #1
End Sub
Private Sub Cmd2_Click()
Text1.Text = ""
s = 0
For i = 1 To 100
If a(i) Mod 2 <> 0 Then
Text1.Text = Text1.Text & a(i) & Space(1)
s = s + a(i)
End If
Next
putdata s
End Sub |
第二部分，模块程序部分：（如没有，需要自行添加一个标准模块）
Sub putdata(ByVal a As Integer)
Dim sFile As String
sFile = "\out.txt"
Open App.Path & sFile For Output As #1
Print #1, a;
Close #1
End Sub |
|
