vb程式設計題：設計一個字元大小寫的轉換程式，
2樓：匿名使用者
字元來大小寫轉換程式，當文字框
源text1中輸
入大寫字母，在文字bai框text2中同時顯示其小du寫zhi字母dao;當文字框text1中輸入小寫字母，在文字框text2中同時顯示其大寫字母；當輸入其他字元，則原樣輸出。
建立兩個文字框
private sub form_load()text1.text = ""
text2.text = ""
end sub
private sub text1_keypress(keyascii as integer)
dim x as string * 1
x = chr$(keyascii)
select case x
case "a" to "z"
x = chr$(keyascii + 32)case "a" to "z"
x = chr$(keyascii - 32)case else
x = x
end select
text2.text = text2.text & xend sub
