有text1/text2和text3。判斷如果3個text都為空，在text1寫入combo1。如果text2和3為空，text1不為空，在text2寫入combo1。如果text3為空，text1和2不為空，在text3寫入combo1。折磨我一晚上了，沒搞對 求助
uj5u.com熱心網友回復：
If Text1.Text = "" Then
Text1.Text = Combo1.Text
ElseIf Text1.Text <> "" And Text2.Text = "" And Text3.Text = "" Then
Text2.Text = Combo1.Text
ElseIf Text1.Text <> "" And Text2.Text <> "" And Text3.Text = "" Then
Text3.Text = Combo1.Text
End If
很簡單的。
