vb程序代码

Question

各位大侠：我自己写的程序 怎么设置开机就运行啊 vb代码是什么？？？？？

Answer 1

要通过注册表操作来进行!注册表RUN下写入键值可以达到这个效果!
比如你按下一个按钮来实现开机自启动!
Private Sub command1_Click()
CreateKey "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run"
SetStringValue "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run", "这里写键值的名称随你自定义的", "这里写你程序的路径" '开机启动自己
end sub
然后你添加个模块,里面写(我写的是通用的模块可以进行注册表的各项操作便于你学习就都写出来了,有问题可以百度留言或Q340231101 ):
Type FILETIME
lLowDateTime As Long
lHighDateTime As Long
End Type

Answer 2

将你写的代码保存为可执行文件

然后将该文件（或者该文件的快捷方式）复制到

C:\Documents and Settings\Administrator\「开始」菜单\程序\启动

即可

Answer 3

还是写注册表吧，RUN项
