itead hat mit dem sonoff Modul einen sehr günstigen ESP-8266 basierten WLAN Stromschalter im Programm. Kostet derzeit bei itead unter 5$, allerdings mit ca. 8$ Versand. Wenn man aber gleich vier davon bestellt, lohnt sich das gegenüber anderen China-Versendern, die diese Modul für ca. 10$ verkaufen.
Das Ding lässt sich wunderbar mit einer eigenen Firmware flashen, wenn man einen 4-Pin Header einlötet und einen USB-TTL Konverter mit 3.3V hat.

I already posted one article about using injectDLL, one about subclassing a foreign window. This time injectDLL is used to start and stop an application when another app is started. Remember that every DLL listed inside the MULTI_SZ registry key HKLM\System\Kernel\injectDLL is loaded into every process.
I would like to add some battery and wifi indicator to a full screen Remote Desktop Mobile (RDM) session. There are two specialized applications that display a small bar graph on the right of the screen, one for the battery level and one for the WiFi RSSI.
The upper right one is for the WLAN RSSI and the lower bar shows the battery charge level.
As these apps should only add there display when RDM ist started, I added them to an injectDLL.

The app starts with the main screen where you select a bluetooth printer, connect, select a demo file and let it print.

As I needed a tool to test the maximum MTU size for a network, I needed a ping tool where I can define the packet size and the DF (Do Not Fragment-Flag). As I did not find such a tool, I wrote PingNG.
It is a simple tool but the code had to avoid some pitfalls.
