.Net Native Interface Library

The .Net Native Interface Library (DotNetNativeInterface) is a native programming interface which provides a way for programming languages such as C, C++, Fortran, Assembly, Pascal, Java, VB etc to interact with applications and libraries written in any of the .Net languages (such as C#, VB.Net etc). Programmers can use DotNetNativeInterface native methods to access .Net 3rd party libraries or .Net Framework Libraries without the need for registry entries, COM registrations or changes to the .Net libraries. The following examples illustrate when you need to use DotNetNativeInterface native methods: 1. You want to access and use .Net Framework Class Library in your application. 2. You want to access and use 3rd party .Net Libraries in your application. Competitive Advantages: 1. Access to .Net Framework Class Library. 2. No COM registration of .Net Libraries is required when deployed. 3. Allows any programming language to consume .Net libraries as if they were native code.

SplashAbout

Every application should have a Splash screen and an About dialog. This component makes it as easy as dropping it onto your main form and calling a couple of methods. If you set VersionInfo in your Project Options, then most properties are automatically picked up. Two methods: SplashAbout1.ShowSplash (in form1.create method) and SplashAbout1.ShowAbout. No bloat: Windows are created on-the-fly and destroyed on close. OptionalIcon can be multi-resolution Set OptionalIconSize and the best available resolution/size will be displayed in Splash and About dialogs. Debug Logging available. Compile the /demo project to see what it can do Debug Logging (set DebugMode = TRUE) Windows and Linux.

AppM Build Automation

AppM Build Automaiton is an open source and automated software application that is used to construct and build projects on different operating systems and using different development environments. General principles of implementation: -Each project must have a Build Project File, containing the necessary information on the construction of the project. For example, a unique name of the project, dependence on other projects and libraries, methods of construction, etc. Thus, the entire repository should be marked by the project description files to provide unambiguous information on the projects and their dependencies. - AppM Build Automaiton must be able to perform different actions (project construction, external applications launch, file copying, etc.) which are needed to build a -product. - All operations with projects should be carried out on the basis of information that build tool derives from the project description files.

PureGEM

PureGEM started out as a VCL/LCL style library written in PurePascal. After the system was working, I saw ways to increase the speed while reducing code size, so the design drifted somewhat. Since PurePascal is "Turbo Pascal 7.0 compatible" a number of VCL style features needed to be implemented differently. Namely TNotifyEvent's are replaced with owner recursive methods. RTTI features are implemented via set's. Initially I had planned to use more of the GEM API, but some of the features I wanted required replacing all window elements. This is a new library, so expect code to change. I will be working on this for the next 1-2 years. cheers Derek

TB_PrintScreen

This software is not for directly use in your development and it was finished in 2011 spring. It demonstrates one possible efficient way to build a print-screen software. Due to that I was a newbie in terms of design mode in 2011, so the codes are not so friendly in reading. You can mainly focus on the Main.cpp file in which many useful methods, routines are implemented. Hope you can get what you want here!
