Source code illustrating various useful and interesting bits of Windows programming. At present all the source is C++.
classes
C++ classes written by John Rennie to simplify various aspects of Windows programming. In general these classes concentrate on providing a simple interface to the more commonly used features rather than trying to provide a comprehensive but huge and complex interface as the MFC classes do.
Some of the applications in this archive use these classes.
- cisapi.zip 41278 20/06/1999
- CIsapi is a simple C++ class to encapsulate the interface provided by Microsoft Internet Information Server to ISAPI dlls. It comes with an example ISAPI dll to show how it is used.
- eventlog.zip 11269 09/08/1999
- A C++ class to encapsulate the Win32 registry api.
- internet.zip 38042 25/08/1999
- Various classes for handling Internet operations. For example there is a class for submitting HTTP POST requests, another to encapsulate FTP transactions and so on. Some of these classes require the Microsoft wininet dll, but this ships as standard these days so that shouldn't be a problem. Some of the classes that do not use wininet.dll require the CRhsSocket class.
The CRhsSMTP class was updated on 24/8/99 to improve behaviour with ESMTP servers.
- misc.zip 67,958 18/12/2000
- Miscellaneous C++ classes.
- rhsado.zip 10128 20/06/1999
- CRhsADO is a group of C++ classes to encapsulate the ADO COM interface. At present the classes only support read queries and cannot update data (except by using a SQL update or insert query). The zip includes a test application to illustrate the use of the classes. This application requires the CRhsVariant and CRhsDate classes from misc.zip.
- rhsbitmap.zip 11141 20/06/1999
- CRhsBitmap is a class to encapsulate Windows bitmaps. The class allows bitmaps to be easily read and displayed, though not to be modified or written back to files. The class is designed to be extensible to other formats of bitmap but this hasn't been implemented yet.
- rhsdao.zip 20177 20/06/1999
- CRhsDAO is a group of C++ classes to encapsulate the DAO COM interface. The classes allow simple querying and modifying of databases. The zip includes a test application to illustrate the use of the classes. This application requires the CRhsVariant class from misc.zip.
- rhsgraph.zip 16829 20/06/1999
- CXYGraph is a simple C++ class to draw XY graphs. The class is very basic and likely to be useful only where a simple graph is required and aesthetics are not that important.
- rhsrtf.zip 52062 20/06/1999
- CRhsRTF and CRhsOleRTF are C++ classes which provide a fairly abstracted encapsulation of the Windows Rich Text control. The classes handle loading, displaying and saving of the RTF control and the CRhsOleRTF allows object embedding too. An application is included to show how the classes are used. The classes and the application require various classes from misc.zip.
- rhssock.zip 11062 25/08/1999
- CRhsSocket is a C++ class encapsulating an IP socket. The class provides a simple but powerful and comprehensive interface which greatly simplifies the writing of socket applications. The zip includes a test application to read data from a Web server.
- Updated 24/8/99 to add a select method.
- secdesc.zip 9305 20/06/1999
- CRhsSecurityDescriptor is a C++ class to encapsulate an NT security descriptor. It allows a security descriptor to be created and optionally initialised from any object like a file or registry key. Entries can be added to or removed from the descriptor and the descriptor reapplied to an object.
- secobj.zip 21065 28/06/2006
- CSecurableObject and derived classes are C++ classes which encapsulate objects which have security descriptor. Note that these classes encapsulate the object, for example the file or registry key, while the above CRhsSecurityDescriptor class encapsulates the security descriptor (the classes do not use or depend on each other). The zip includes an example app showing how to modify file security.
Other
Other source code.
- dragdrop.zip 89855 20/06/1999

- dosdevice.zip 39,565 20/06/1999
- Some C++ apps to play with NT device names. Similar functionality to the subst command provided with NT, but the apps here work at a lower level and are more powerful (and dangerous!).
- fileowner.zip 14530 20/06/1999
- C++ app to change the owner of a file on NT by modifying the file security descriptor.
- grepregistry.zip 33838 20/06/1999
- C++ app which can do registry searching and replacing using regular expressions.
- kill.zip 15133 20/06/1999
- C++ app which allows administrators to kill any process including processes they do not own. It works by enabling the debug privilege and connecting to the process as a debugger. Once this is done the process can be killed.

- ntw2nts.zip 17012 20/06/1999
- C++ app to show how NT Workstation can be modified to become NT Server by fiddling the registry. NB not tested for Service Pack levels greater than 2.
- posix.zip 11662 20/06/1999
- NT Posix apps to rename and delete files. Occasionally useful for attacking files with names like LPT1 or NUL that the NT Win32 subsystem will not open.
- reconcile.zip 40478 19/07/2008
- C++ app to reconcile the contents of two directories by:
- creating files that exist in the source but not the destination
- copying files which are newer in the source than in the destination
- deleting files in the destination which do not exist in the source
I've used this for some years to synchronise many Gb of data in two huge directory trees and it has been totally reliable.
- regsetvalue.zip 22221 20/06/1999
- C++ app to test or update registry values. Particularly useful for setting registry keys from users login scripts.
- resetpassword.zip 32093 06/08/1999
- C++ service to reset a lost administrator password on Windows NT.
- showdiracl.zip 23253 28/06/2006

- C++ app waits for the specified number of seconds. Useful in batch files to pause execution for a period.
- su.zip 20880 20/06/1999
- C++ app for NT which switches the user to another user account. Like the unix su command this is usually the administrator account, but any other account can be switched to. Includes some interesting aspects of NT programming including logging in as other users and managing window station security. Requires the CSecurableObject classes from secobj.zip. This app isn't as useful as it could be because it requires several NT privileges to be granted before it will work.
- tee.zip 13861 20/06/1999
- C++ filter to direct output from stdout to a file as well as to stdout.
- testodbc.zip 25620 20/06/1999

Applications which have a windowed interface.
- brs.zip 23999 20/06/1999
- C++ app to log off, shut down or reboot NT. Can be used to reboot machines remotely. Can also be used as a console app.
- commandz.zip 519947 20/06/1999
- C++ app which pops up a window when a hot-key is pressed and allows a command to be typed. Provides usual file manipulation commands which are more powerful than their NT equivalents. Also includes extra libraries for a range of commands including ODBC queries, network mapping directory syncronisation and others.
- dezktop.zip 280338 20/06/1999
- Alternative shell for NT. Quite widely used on NT3.51 and earlier, but largely superceded by Explorer on NT4. C++.

- fmstart.zip 19475 20/06/1999
- File Manager extension which places a button on the toolbar to run the selected file. The process is started in a separate thread which avoids File Manager hanging up when starting a slow app like MS Word by clicking a .doc file. C++.
- procview.zip 56973 23/05/2000
- Shows processes running on the system and can kill processes. Similar information to the Process tab in the NT Task Manager, but gives more memory information and can kill processes which you don't own. Interesting as an example of how to use the NT performance counters and contains a class to simplify using performance counters. C++.
- telephone.zip 99390 20/06/1999
- Simple but very popular telephone number application. C++.
- walker.zip 147229 20/06/1999
- Shows detailed memory usage of an application including all dlls the process loads. C++.

- adminsvc.zip 43498 20/06/1999
- Service which allows applications to be run from a login script with administrator access even if an ordinary user is logged on.
- lpdsrv.zip 56405 20/06/1999
- A Berkeley LPD server. Written because I found the LPD server in NT rather unreliable.
- rhstelnet.zip 106791 20/06/1999
- A telnet server for NT. Tackles some quite tricky problems of logging users on and managing security.
- rhssimplesmtp.zip 51474 25/08/99
