I have to connect (using Bluetooth) a handheld computer of the sort used by parcels delivery drivers, and a battery operated receipt printer. The computer manufacturer's preferred bluetooth doesn't wake the printer when it goes to sleep (after 60 seconds, to conserve battery). They have given me an SDK with some dlls which do not import into VB2005. I (think I) have to use PInvoke to get round this problem. One of the dlls they supply is supposed to allow me to wake the printer up by using a call from it, but which dll, which call?
I am reasonably proficient in VB.Net, but not VC.
Will PInvoke.Net help me or should I look elsewhere? Thank you.
