3. 記事本編程用的代碼有哪些啊怎麼用啊
記事本可以用來編寫所有的程序代碼,任何語言,但是編寫好後編譯必須使用與其語言相對應的編譯器進行編譯,這個記事本沒那功能.
還有就是記事本沒有那專業軟體的糾錯/語法檢測等功能,用於編寫程序比較容易出錯,所以一般不用記事本來編寫程序,而使用專業的軟體來編寫.
4. 簡易記事本代碼
'以下是讀記事本代碼，讀取後的數據存儲在數組hs()中：
Dim i As Long, hs() As String
i = 0
ReDim hs(0)
Open App.Path & "\1.txt" For Input As #1
Do While Not EOF(1)
ReDim Preserve hs(i)
Line Input #1, hs(i)
i = i + 1
Loop
Close #1
'以下是寫記事本代碼：
dim filename as string
filename = "這是第一行" & chr(13) & chr(10) & "這是第二行" & chr(13) & chr(10) & "這是第三行" & chr(13) & chr(10)
Open App.Path & "\2.txt" For Output As #1
Seek #1, 1
Print #1, filename
Close #1
5. 求記事本編程代碼！
你「開始」->「運行」->輸入「regedit」
按下ctrl+F，輸入「Intarnat Explrcr」，把找到的東西全部刪除。
同樣找出「360安全網址大全」，把找到的全部刪除。
你的桌面上 就不會有了。當然，如果這是由電腦中某個程序不斷生成的話，你必須找到那個程序，先把它刪了才行。
