我需要从64位的exe访问32位的dll [英] I need to access a 32bit dll from a 64bit exe

问题描述

我知道我读了所有关于代理过程，我能够创建一个代理COM，但它或者都工作在32位或所有工作在64位。

将是正确的结构？

1）32.dll < - 64.com < - 64.exe
2）32.dll< 32.com< - 64.exe

我试过上述两种方法，但是没有成功调用32.dll？

解决方案

我不太了解你指的代理COM，但我已经解决了这个问题（使用64位exe的32位dll） COM对象在中间：

32.dll < - > 32bit-out-of-process-com-server.exe <64> / p>

对不起这可能是你的意思是32.com，不确定，但确保中间的COM对象生活在一个.exe（过程中），而不是在dll。这是因为同样的原因，你不能加载到64位进程原来的32.dll。

I know I read all about surrogate process, and I was able to create a surrogate COM but it either all works in 32bit or all works in 64bit.

What would be the correct structure?

1) 32.dll <- 64.com <- 64.exe 2) 32.dll <- 32.com <- 64.exe

I tried both of the above but I did not succeed to call the 32.dll?

解决方案

I'm not too informed about the surrogate COM you refer to but I've solved this problem (Using a 32bit dll from a 64bit exe) by introducing a COM object in the middle:

32.dll <-> 32bit-out-of-process-com-server.exe <-> 64.exe.

Sorry this might be what you mean by 32.com, not sure, but make sure the intermediate COM object lives in an .exe (out of process) and not in a dll. This is for the same reason you can't load the original 32.dll into the 64 bit process.
