DLL is a common file, which integrates many functions of the program. In general, it cannot be executed directly. A common method of use is to use another *. EXE to call its execution to display its internal functions. Also, the *. ocx file is similar to this file, that is, the common COM file.1. BriefAll functions of Windows APIs are included in the DLL, of which three are the most important.(1)

. Second, what is API What is the "interface" mentioned earlier? Because DLLs cannot be jammed into programs like static library files, how to let the program know that the implementation of the code and the file is a problem, Microsoft has made a standard specification for DLL technology, for each DLL file clearly labeled its function name, the program as long as the standard specification to find the re

We use examples to learn how to compile DLL files using gcc. The following example shows the process. There are three files in total: Hello. c. dll. H and DLL. c. hello. the content of the C file is as follows # include {Hello (); Return 0;} among them, the hello () function is a function provided by the dynamic Connection Library.The

DLL, dll syntax By default, all data segments are independent of processes, and each process has its own copy. However, sometimes a process shares a data segment. Therefore, the VC ++ compilation Connector provides a special syntax. The following is a typical example. A Shared data segment named Shared is created, there is only one variable g_hwndOwner in this data segment. ////////////////////////////////

[C # dynamic calling of DLL functions written in C ++] Dynamic DLL loading requires the use of Windows API functions: loadlibrary, getprocaddress, and freelibrary. We can use these three functions in C # using dllimport. [Dllimport ("Kernel32")]Public static extern int getprocaddress (INT handle, string funcname ); [Dllimport ("

Statement: I just want to record my learning experience and may be able to help others. If they are similar, please forgive me.DLL that can be implemented in Visual C ++ 6.0Visual c ++ 6.0 supports automatic generation of Win32 DLL and MFC Appwizard DLL. Win32 DLL does not use the MFC class library, and the exported function is a standard C interface, non-MFC and

library so that the application can access these functions. At this time, The address of each function is parsed and dynamically connected to the program-this is the term The Origin of "dynamic connection.Another benefit is that when you update the version and function of your function, the static connection The amount of work required (assuming that windwos has thousands of such functions, a total of 100 If multiple programs are used, the static connection needs to be updated 100000 ti
