Ask a programming question about the .dll dynamic link library

firesky999

I want a program to dynamically load the dll files I wrote. For example, I have several .dll files that implement the same interface through different methods. They can be replaced with each other. Suppose they are called a1.dll, a2. dll, a3.dll ... I hope that users can select the .dll files they need to use during the use of my program. How to change it?

Positive solution upstairs using LoadLibrary function

霜之哀愁

Load all three libraries with loadlibrary,
Then see which library function to execute, and use GetProcAdress to pass in the handles of the three libraries. . .

If you want to achieve complete automation, I am afraid it is impossible, after all, it is not a C ++ virtual function. . .
