Ad-hoc wireless connectivity issues
Hello ECE blogger readers! Once again I’m here with a technical issue that was tough to trace and eliminate. It involved a Symbol MC50 PDA and a Linksys WUSB54G wireless adapter. The trouble I had was reconnecting the PDA to the access point in ad-hoc mode. It was possible to get an initial connection by setting up an ad-hoc network with the PDA, enabling the wireless …

Automating MapPoint in C++ with the built in GPS enabled
Project54 is currently developing a GPS Navigation application to be used in police cruisers. This navigation application is using MapPoint 2006 as its routing and mapping engine. MapPoint 2006 has an SDK which gives developers software control of MapPoint. With this SDK Project54 developers are able to integrate MapPoint into the Project54 system. However, there …

As it turns out, you may run into a couple of obstacles when installing SPSS under Vista. I certainly did. First, when I ran the installation program I got an “internal error 2738,” which a website told me was due to a problem with the VBScript DLL. When I tried to use regsvr32 to register …

Symbol MC50 battery
So get this…. A couple months ago, I thought I bricked one of my Symbol PDAs at work. Yeah, people made fun of me for being a bit thorough in my testing. As it turned out, it was nothing I had done. Only today had I found out what the true nature of the problem was. When the battery gets low, the PDA for some reason shuts itself off. When you press the power …
