C + + Write DLL, in C + + call is actually a relatively simple thing, call DLL function method In fact there are many, say one of the most common method:1. Create a new solution, file--New project->visual C++->WIN32 Console application->next->dll-> complete.2. Static (. lib), configuration type, project properties.3. lib2.h File:Class Lib2 {public: Lib2 (); ~lib2

Api functions are the cornerstone of building Windws applications. For every Windows application development tool, the underlying functions provided by API functions call Windows Api functions indirectly or directly, at the same time, in order to achieve function expansion, interfaces for calling WindowsAPI functions are generally provided, that is, they can call dynamic connection libraries.

Local visual c ++ there are basically four methods to call . net Program set. Microsoft All-in-One code framework there are some examples to illustrate this problem. 1. Local VC ++ model call CLR hosting APIs managed by CLR , download and call . net assembly. ( All-in-One c

to the called function code, thus saving memory resources. From the above description, we can see that the DLL and.

In a task completed last week, I found a bit confused: When writing C ++ DLL for VB call, the def file must be used to define the export symbol. OtherwiseProgramFailed to link. We all know that the def file is used to prevent the C ++ compiler from renaming the function. Another alternative to achieving the same effect is to use the extern "C" identifier. If the DLL is called by C ++, C #, Java, and so on, the latter can work well. However, VB canno

that is called as another method In the following exercise, we will continue to use the Mathsoperators application. This time, we'll look at some method calls. 　　 Research method call 1. Return to methods project. If you have just completed the previous exercise, the project should already be open in Visual Studio 2005, otherwise, from the \microsoft Press\visual
