It has shipped with Windows versions since Windows 95 OSR2.5 for use by other Windows components; earlier versions shipped with the CRTDLL.DLL library instead. In older versions of Windows, programs which linked against MSVCRT.DLL were expected to install a compatible copy in the System32 folder, but this contributed to DLL Hell because many ...
Pointers are returned in EAX on 32-bit systems and in AX in 16-bit systems. Strings are returned in a temporary location pointed by the @Result symbol. This calling convention was common in the following 16-bit APIs: OS/2 1.x, Microsoft Windows 3.x, and Borland Delphi version 1.x.
windows.h is a source code header file that Microsoft provides for the development of programs that access the Windows API (WinAPI) via C language syntax. It declares the WinAPI functions, associated data types and common macros. Access to WinAPI can be enabled for a C or C++ program by including it into a source file: #include <windows.h>
It was also available in a bundle called Visual C++ 16/32-bit Suite, which included Visual C++ 1.5. [14] Visual C++ 2.0, which included MFC 3.0, was the first version to be 32-bit only. In many ways, this version was ahead of its time, since Windows 95, then codenamed "Chicago", was not yet released, and Windows NT had only a small market share ...
In the thiscall section, you stated "Windows API functions don't have a this pointer!", well, the section was already talking about *C++ member functions*, and non-static was obviously implicit but should be noted. I have reverted to Letdorf's version, though I agree that Windows functions can be misleading.
The calling convention of a given program's language may differ from the calling convention of the underlying platform, OS, or of some library being linked to. For example, on 32-bit Windows, operating system calls have the stdcall calling convention, whereas many C programs that run there use the cdecl calling convention. To accommodate these ...
The Active Template Library (ATL) is a set of template-based C++ classes developed by Microsoft, intended to simplify the programming of Component Object Model (COM) objects. The COM support in Microsoft Visual C++ allows developers to create a variety of COM objects, OLE Automation servers, and ActiveX controls.
At that time, C++ was just beginning to replace C for development of commercial software, driven by the rising of the Windows platform and the rapid adoption of object-oriented design. During this period, OWL was a popular choice for Windows application development. In 1992, Microsoft introduced MFC as part of Microsoft C++ 7.0. As a similar ...
