VB6安装驱动源码

发布时间:2024-05-27 16:12:24

A. VB程序源码如何使用

需要安装vb6.0开发软件
如果安装了,就可以直接打开源码测试了,后缀名是vbp,(就是vb的工程文件)
如果没有安装vb6.0,还想打开源码看程序,那就右击 用记事本 打开后缀名为frm的文件,他是vb的窗口文件,源码都在他里面

一般得源码是没有生成exe可执行文件的,那样文件太多,太大,浪费空间
如果你自己想生成exe可执行文件,那就vb6.0得文件菜单中把文件保存成exe可执行文件就可以了,

发下是我几年前写的(参照)一个VB驱动摄像头的代码,不知道现在还能不能用,因为文件总的很长,这只是其中的一小部分,希望对你有所用.(要不就和我联系,给你源码)
