Hello ,
I am a master student and I am working in a small VOIP application for my thesis. I have a HTC Touch Elf and my problem is that I cannot get working the ear-speaker , the sound is always coming out from the rear speaker. I need to get this working to my thesis presentation. I went around the forums and the problem seems to be that HTC didn't implement this feature as regular call to Windows CE API , but instead they use DeviceIOcontrol directly to switch between the speakers. I have IDA Pro, and I am starting to go into the world of disassembling to get the good value to pass as a IOCTL. I also have in my possession a commercial VOIP application that does this switching. So here are my questions:
Should I try to disassemble some dll's in the \windows , in order to find this code? which ones? any ideas?
How can I copy a dll file out of the \windows folder to my desktop computer? Windows mobile doesn't allow me to copy system files...
Should I try to disassemble first this commercial application and try to find there the good code?
I hope you can help me with this , I would be very appreciated.
