1. 新建一个工程，完成“加法器”程序的设计。 参考答案：
Private Sub Command1_Click()
Text3.Text = Str(Val(Text1.Text) + Val(Text2.Text)) End Sub
Private Sub Command2_Click() Text1.Text = \ Text2.Text = \ Text3.Text = \ Text1.SetFocus End Sub
Private Sub Form_Load()
Form1.Caption = \加法器\ '文本框清空 Text1.Text = \ Text2.Text = \ Text3.Text = \ '设置文本框右对齐 Text1.Alignment = 1 Text2.Alignment = 1 Text3.Alignment = 1 '屏蔽对Text3的编辑 Text3.Locked = True Label1.Caption = \ Command1.Caption = \＝\ Command2.Caption = \清空\End Sub
Private Sub Text1_KeyPress(KeyAscii As Integer) If (KeyAscii < 48) Or (KeyAscii > 57) Then KeyAscii = 0 End If End Sub
Private Sub Text2_KeyPress(KeyAscii As Integer) If (KeyAscii < 48) Or (KeyAscii > 57) Then KeyAscii = 0 End If End Sub
2. 新建一个工程，完成“健康称”程序的设计。具体要求如下： 参考答案：
Private Sub Command1_Click() Dim bzh As Single
bzh = Val(Text1.Text) - 105
If Val(Text2.Text) > bzh * 1.1 Then
Label5.Caption = \偏胖，注意饮食\
ElseIf Val(Text2.Text) < bzh * 0.9 Then Label5.Caption = \偏瘦，增加营养\ Else
Label5.Caption = \正常，继续保持\ End If End Sub
Private Sub Text1_KeyPress(KeyAscii As Integer)
If KeyAscii < 48 Or KeyAscii > 57 Then '输入非数字 KeyAscii=0 End If End Sub
Private Sub Text2_KeyPress(KeyAscii As Integer)
If KeyAscii < 48 Or KeyAscii > 57 Then '输入非数字 KeyAscii=0 End If End Sub
3. 新建一个工程，完成应用程序的设计，具体要求如下：
参考答案：
Private Sub Command1_Click() If Form1.WindowState = 0 Then Command1.Caption = \最小化(&B)\Form1.WindowState = 2
Command1.Left = (Form1.Width - Command1.Width) / 2
Command1.Top = (Form1.ScaleHeight - Command1.Height) / 2 Else
Form1.WindowState = 0
Command1.Caption = \最大化(&L)\
Command1.Left = (Form1.Width - Command1.Width) / 2
Command1.Top = (Form1.ScaleHeight - Command1.Height) / 2 End If End Sub
