Above is part of the code, crazy, always has a problem, and finally this problem, the program debugging, no problem, after running, open the serial port receiving data will prompt pictures show,
RS. Exe of 0 x7582845d (KernelBase. DLL) the most possible exceptions: Microsoft c + + exceptions: memory location 0 x00000000 [rethrow],
RS. Exe of 0 x7582845d (KernelBase. DLL) the most possible exceptions: Microsoft c + + exceptions: memory location 0 x003bd7d4 COleDispatchException,
Really don't know why? Please everyone a great god solve

CodePudding user response:

Debugged see where the problem?

CodePudding user response:

Catch, see what exceptions thrown by the first, and then the break with, and see where the problems step

CodePudding user response:

I met the same problem with you, I transfer data via bluetooth adapter serial port after receiving this question, can directly use the usb serial port receives the data, don't know whether you are using a bluetooth transmission is out of the question, I'm also thinking how to solve the problem of bluetooth receives this,

CodePudding user response:

Is there a map?
DECLARE_EVENTSINK_MAP
BEGIN_EVENTSINK_MAP
ON_EVENT
END_EVENTSINK_MAP

CodePudding user response:

Mscomm is vc6 era, believe you also very vexed the varient, with a third party class, several functions can solve problems at http://blog.csdn.net/sunnyloves/article/details/5575995

CodePudding user response:

Thank you, and find the problem, though, but the debug exe files on other computers are running well and no problems, I don't know why! This first

CodePudding user response:

I also met the same problem, how to solve?
