Auto C is a software that facilitates creating user interfaces in C programming language. It allows developers to create Windows applications by drawing controls on a form using a WYSIWYG visual-style environment that includes a toolbox, properties box, and property pages. It also helps create the skeleton for a generic SDK C application.

With a WYSIWYG (what you see is what you get) design environment, Auto C makes it possible to create user interfaces in a simple and intuitive way. The software works with Windows 2000, Windows XP and later versions. It is an add-in for WoLoSoft International's SuperEdi software, which is a prerequisite for using Auto C.
Auto C integrates Microsoft ActiveX Control Pad with SuperEdi, and supports the use of four popular C / C++ compilers. It enables you to create a generic C application based on a user interface that you create and edit like a VB form, without creating dialog box RC scripts.
Auto C generates the C code to perform various tasks such as changing foreground and background colors for many controls, specifying the font for a control to use, subclassing a picture box just by drawing controls inside it, specifying the tooltip for a control to display, creating a toolbar and buttons and many more. The software creates RC script for menus and accelerators, and supports various controls such as Command Button, Check Box, Option Button, Frame, Text Box, List Box, Combo Box, Label, Picture Box, Tabstrip, Slider, Up-Down Button, Scrollbar, Toolbar, Progress Bar, Status Bar.
Auto C also supports creating and editing menus in a point-and-click visual style. It allows for the use of free compilers including Borland Free C++ Compiler 5.5, LCC-Win, Pelles C, Open Watcom C / C++. It is ideal for Visual Studio 6 owners, and ActiveX Control Pad is included on MSDN Library 6 CD.
The software helps de-mystify the fundamentals of Windows by generating the code needed to load a DLL and use the DLL's exported functions. Refer to the help file for more information on how to use this software.
Version 3.7.70: The same version now works with Windows 10 as well as Windows 8.1 and earlier.
