Don't forget to disable use of precompiled headers for this CPP file! The class uses the NDIS User mode I/O driver ( NDISUIO) to perform AP scanning. You have to add CWifiPeek.h and CWifiPeek.cpp to your project. It can be used in non-MFC applications, too. The CWifiPeek class does all the Wifi query stuff. If you add other SDKs to the demo project, you might need to change a couple of compiler/linker settings. PeekPocket should run fine on WM5 and WM6 devices, too. You can compile the application with Visual Studio 2005 and the PocketPC 2003 SDK. If these do not help, sometimes a reset will. If you have configured an automatic connection to an AP, try removing it.If the PDA has an ActiveSync connection to your PC, disconnect it.In such a case, you can try the following: Your Wifi adapter should be displayed in the combo. You can also set network type and security filters there. You can set the list font size and scanning speed on the Options tab. follow one signal without seeing any other APs. If you tap an AP name, you can "go large," i.e. An inactive AP is one that is not currently visible. Secure APs are printed in red, while inactive ones are greyed out. Just turn your WLAN on, run the application and see the APs listed. CCustomButton - custom Button controls (button, checkbox, radio, etc.).CCustomSlider - a custom Slider (trackbar) control with BMP support.CCustomTabCtrl - a custom Tab control that runs fine under WinCE/PocketPC.CColoredDlg - a dialog base class that supports custom colors for child controls.CWifiPeek - a class that can be used to list nearby Wifi devices.This article features the following classes: I hope you find these classes useful, too. I also included different custom MFC controls I coded before: a bitmapped slider, a tab control and buttons. This way it has an acceptable outdoor visibility and you can follow a single signal without having to see the APs of your neighbours flashing on your screen. The other mode displays the signal strength of a selected AP with large numbers. The first is a colored list of all nearby APs. So, I coded a simple scanner that has two view modes. I did a bit of research and it turned out that getting Wifi information is rather simple with the NDISUIO driver that is available on PocketPC 2003 and newer systems. I wanted to know how AP scanner software works. I set up wireless at home a couple of weeks ago and became interested in wireless tools.
