64位win7下LSP开发出现问题，调试不能进入WSPConnect、WSPSend、WSPRecv等函数。
在32位XP下，和32位Win7下没有问题。我做的LSP dll为32位的，调试的IE浏览器也是32位的。或者说在64位系统下运行32IE应该调用32位的LSP dll ，逻辑上没有问题。

网上的
64 bit operating systems are becoming more and more popular every day.  Therefore, your LSP needs to be 64 bit as well – otherwise you will not be able to install it on a 64 bit operating system.

You will need to install the 32 bit LSP first.  When you run a 32 bit application on a 64 bit operating system, that application is first going to load the 32 bit DLLs and the 32 bit LSP.

Now, when you run a 64 bit application on your 64 bit operating system, that application loads the 64 bit DLLs.  This obviously means that you will need to have the 64 bit LSP installed.

The operating system is going to keep both of the different LSP stacks:  32 bit LSP and 64 bit LSP.  You have to have an installer in both versions as well.  When you are installing, be sure to install the 32 bit LSP first.

我跟64位操作系统没有关系啊  用的都是32位的应用 32位的LSP
