我正在使用vb.net ..我是vc ++的新手。在某些情况下，我需要在vc ++中编写一些代码。我需要vc ++，原因如下。
我在vb.net中创建了一个dll并根据vb.net dll创建了一个tlb文件。我在我的vc ++代码中使用静态值导入物理tlb文件，如下所述。
#import“C：\ Documents and Settings \ Ankit.ass \ My Documents \ Visual Studio 2010 \ Projects \ SetupValidationPro \ SetupValidationPro \ bin \ Debug \ SetupValidationPro.tlb”named_guids raw_interfaces_only
这工作正常..我的问题是，我想使用vc ++动态或运行时创建一个tlb文件并动态加载该tlb文件。
所以，我需要在vc ++中嵌入一个dll。如何在vc ++中嵌入dll？
现在，我想将我的嵌入dll提取到一些物理文件中。那么如何在vc ++中将我的dll提取到物理位置？
并且，在最后一步，我想使用vc ++动态创建一个tlb文件，并动态加载tlb文件。
我怎样才能做到这一点？

我经过大量的谷歌搜索后解决了这个问题。这是我的问题解决的代码。我不需要本机代码..

这是解决我的问题的MFC代码。此代码嵌入资源，提取资源并在运行时注册类型库。
