Question

用VBA如何显示把textbox3的值设置为textbox1+textbox2的值,并且保证1和2中间有空格?textbox2后面是回车?

textbox3在原有的基础上还能在重复累加textbox1和textbox2的值?

Answer 1

Private Sub CommandButton1_Click()
If TextBox3.Text = "" Then
TextBox3.Text = CDbl(TextBox1.Text) + CDbl(TextBox2.Text)
TextBox1.Text = ""
TextBox2.Text = ""
Else
TextBox3.Text = CDbl(TextBox1.Text) + CDbl(TextBox2.Text) + CDbl(TextBox3.Text)
End If
End Sub
