我不知道在哪里得到这个句柄

它作为一个参数传递给你的DLLMain（）入口函数。

如果插件不能访问它的DLLMain条目函数，它可以在自己的内存块上使用VirtualQuery函数，并使用填充的MEMORY_BASIC_INFORMATION结构的AllocationBase字段作为其HMODULE。

I have a C++ Windows application myapp.exe which loads several plug-ins.

Plug-ins need to find the path to their DLLs. I can use GetModuleFileName for this, but it need the handle for the plug-in DLL. I don't know where to get this handle. GetModuleHandle(NULL) returns the handle to the executable.

One option is to use GetModuleHandle (GetModuleHandle("myplugin.dll") ) , but this requires the name of the plugin to be hardcoded which I want to avoid.

Any help is appreciated.

I don't know where to get this handle

It's passed as a parameter to your DLLMain() entry function.

If the plugin can't access its DLLMain() entry function, it can use the VirtualQuery function on a piece of its own memory and use the AllocationBase field of the filled-in MEMORY_BASIC_INFORMATION structure as its HMODULE.
