Dynamic Loading of C Classes from DLLs

As developers familiar with C/C programming, it's common to utilize monolithic module files without employing classes. To make DLLs with accessible functions, the __declspec(dllexport) directive is typically used. However, exporting entire classes raises unique challenges.

Late Binding with Dynamic Loading

While dynamically loading a class might be desirable, it's generally not feasible. The typical approach involves implicit linking to the DLL at application startup. If the DLL cannot be found, the application fails to load.

Delay-Loaded DLLs

An alternative option for late binding is to use delay-loaded DLLs. However, this method can be complex to implement.

Implicit Linking for Compile Time Linking

For compile time linking, it is recommended to use the preprocessor technique. When creating a new DLL in Visual Studio and selecting the "export symbols" option, these macros are automatically generated. This approach allows for seamless integration of the class into the application.

Best Practices

Overall, implicit linking with the preprocessor technique is the preferred method for exporting classes from DLLs. This method ensures that the DLL is loaded at application startup and avoids issues associated with dynamic loading.
