3. 记事本编程用的代码有哪些啊怎么用啊

记事本可以用来编写所有的程序代码,任何语言,但是编写好后编译必须使用与其语言相对应的编译器进行编译,这个记事本没那功能.
还有就是记事本没有那专业软件的纠错/语法检测等功能,用于编写程序比较容易出错,所以一般不用记事本来编写程序,而使用专业的软件来编写.

4. 简易记事本代码

'以下是读记事本代码,读取后的数据存储在数组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
'以下是写记事本代码:
dim filename as string
filename = "这是第一行" & chr(13) & chr(10) & "这是第二行" & chr(13) & chr(10) & "这是第三行" & chr(13) & chr(10)
Open App.Path & "\2.txt" For Output As #1
Seek #1, 1
Print #1, filename
Close #1

5. 求记事本编程代码!

你“开始”->“运行”->输入“regedit”

按下ctrl+F,输入“Intarnat Explrcr”,把找到的东西全部删除。

同样找出“360安全网址大全”,把找到的全部删除。

你的桌面上 就不会有了。当然,如果这是由电脑中某个程序不断生成的话,你必须找到那个程序,先把它删了才行。
