关于VBS调用MSWinsock控件
关于VBS调用MSWinsock控件
Windows脚本可以调用MSWinsock控件获得比较强大的网络访问能力，但那个106KB的mswinsck.ocx(V6.0.89.88)不是系统自带的，这使得该控件的实用性大打折扣。而且，脚本要调用MSWinsock还必须克服一个困难。
以"MSWinsock"为关键字，使用百度搜索网页，可以获得至少3个VBS调用MSWinsock控件的例子：获取本机IP、端口扫描和发在"黑防"的《VBS+MSWinsock打造灵巧UDP后门》。但是，当你下载并注册mswinsck.ocx，然后尝试那些代码时，却会得到一个"类别未授权使用(Class is not licensed for use)"错误，错误号0x80040112。那些代码的作者似乎都以为MSWinsock和一般的控件一样，只要用regsvr32注册就能正常使用了，没有实际测试它的可移植性。而转贴文章的人，更不会关心内容是否可靠，一味地复制粘贴而已。结果，网上所有关于VBS调用MSWinsock的例子都是"空中楼阁"，没有一个跑的起来。国内如此，国外也一样。所有对该控件无法使用的质疑，都被人以"需要注册"为理由打发了。当然，也有了解"真相"的人，但其给出的解决方案竟然是用VB重新写个ocx封装MSWinsock，这实在是@#$%^&!。
那么，"真相"究竟是什么？搜索"类别未授权使用"和错误号，这是个好主意，但结果不理想。我们需要逆向思考，为什么原作者不会遇到错误。答案是原作者的mswinsck.ocx不是单独注册的，而是随VB一起安装的。其中的差别在于，后者会安装VB控件的设计时许可证(design-time license)。ActiveX控件的License有两种：设计时(design-time)和运行时(run-time)。当编译调用了某个控件的exe/dll/ocx时，编译器会自动加入该控件的运行时许可证，所以"重新写个ocx封装MSWinsock"这个办法可行。使用脚本直接调用MSWinsock时没有运行时许可证，这时脚本宿主会尝试在注册表中获取设计时许可证，单独注册的MSWinsock没有相应的设计时许可证，所以就出错了。
在VS.NET安装盘里有VB6控件的授权密钥(/Extras/VB6 Controls/VB6Controls.reg)，导入注册表后就能正常使用包括MSWinsock在内的VB6控件了。
