育才学习网1. VB这些代码怎么写
先假定的窗口1名称是form1，窗口2名称是form2。
如果不是自己改之1：点击一个按钮弹出窗口2（弹出后关闭窗口1）点击后的代码：Form2.Show '显示窗口2Unload Me '关闭窗口12：点击一个按键后进度条慢慢的满，同时，标签的内容启动切换（一共分10个内容，周期是1秒）。当进度条满时，自动跳到窗口3。
先添加进度条ProgressBar1和定时器Trimer1，标签Label1代码：Private Sub Form_Load()Timer1.Interval = 1000ProgressBar1.Max = 100ProgressBar1.Value = 0End SubPrivate Sub Timer1_Timer()If ProgressBar1.Value = 100 Then Form3.Show '显示窗口3 Timer1.Enabled = FalseElse ProgressBar1.Value = ProgressBar1.Value + 1 Select Case (ProgressBar1.Value Mod 10) '显示不同的标签10种 Case 0 Label1.Caption = "0" Case 1 Label1.Caption = "1" Case 2 Label1.Caption = "2" Case 3 Label1.Caption = "3" Case 4 Label1.Caption = "4" Case 5 Label1.Caption = "5" Case 6 Label1.Caption = "6" Case 7 Label1.Caption = "7" Case 8 Label1.Caption = "8" Case 9 Label1.Caption = "9" End SelectEnd IfEnd Sub3：窗口4上有一个标签，每2秒更换1个内容，共5个内容，当内容更换完后，自动跳到其他的窗口。这些代码怎么写？悬赏80.先添加定时器Trimer1，标签Label1，窗口变量TDim t As LongPrivate Sub Form_Load()t = 0Timer1.Interval = 1000Label1.Caption = "0"End SubPrivate Sub Timer1_Timer()t = t + 1 Select Case (t Mod 5) Case 0 Label1.Caption = "0" Case 1 Label1.Caption = "1" Case 2 Label1.Caption = "2" Case 3 Label1.Caption = "3" Case 4 Label1.Caption = "4" Case 5 Timer1.Enabled = False '其它要显示的窗口 要显示的窗口.show '其它要显示的窗口 unload me '关闭自己 End SelectEnd Sub。
2. vb代码怎么写
首先在Combo1的List属性中加入"a","b","c"
Combo1.click事件中加入代码：
ID = Combo1.List(Combo1.ListIndex())
Select Case ID
Case "a"
Text1.Text = "111"
Case "b"
Text1.Text = "222"
Case "c"
Text1.Text = "333"
Case Else
End Select
