Description :
A small example component how to use the Serial / COM port using Windows API. Comes with an test application that opens, reads (synchronous and asynchronous) and writes (synchronous and asynchronous) to a configured serial COM port.
This is the result while playing around with the COM port Windows API and could be helpful for everyone that dives into this topic.
Check the readme file in the archive how to use the example application. The source file with the actual COM port access implementation are well documented and should be easy to understand.

Description :
A very simple example on how to read the bootsector of a hard/usb drive, display the important FAT/FAT32/NTFS fields and dump the bootsector to file. Maybe this is a good starting point for some kind of disk-information tool.

Description :
This is my own lame example of coding an api hook. It injects a dll into the address space of a target application. As soon it is loaded, it searches the import table of the target to redirect the MessageBox function. Works only with a few apps but perhaps it is interesting for you :-)

Description :
This tiny programm adds a new menu item to the context menu when you right-click a folder in windows explorer. Selecting this item opens a commandline window in the current directory. This feature can be very handy if you work often with the console und are tired of opening the cmd and changing to your desired directory with cd\.. . Have a look at the screenshots to see what I mean.
This works under XP without problems; under Vista you have to execute this app with administrator rights; under Win7 it's not necessary because you can press the shift key while right-clicking a folder in explorer to get a similar menu item in the context menu.

Description :
This utility change the text color and the text background color of the desktop symbols. Windows XP/Vista has the disadvantage that the symbol text is shaded when the background color is set to transparent. This tool corrects this behaviour by injecting a dll file into the explorer.exe process.
For further information, check the Desktop Symbol Utility Site.

Description :
This is my own implementation of the huffman compression algorithm. Well, it works and is relatively fast but the compression ratio is not that good. It was not that easy to code, so hopyfully the source is useful for you :-)
Version 1.1 is a slightly improved version (more stable and better compression).

Description :
This little application scans an image for a chosen transparent color and save this region to file.

Features:
* supports bmp, png, gif and jpeg files
* choose transparent color from image or type in the RGB values
* preview of region

New in Version 1.1:
* Option to save the region to a C source file. So you don't have to include a rgn file to your resource or as a file anymore. Just include the generated header file to your project and call one single function on startup. That's it :-)
* Possibility to use another layout by specifying the argument -newGUI on the RegionCreator commandline.
Well that's not a real feature but I was playing around how to subclass a window and that's the result: Some little bugfixes / 'beauty changes' and more errorhandling.
