Thank a lot!

I create the new project and change the directory,it works now.
And finally it alerts me " Load MasterCom.dll failed"...

OK,i create a project 'Test', and it says

LINK : fatal error LNK1104: cannot open file "Debug/TEST.exe"
Error executing link.exe.
what happened?

OH..ic...i was just trying to edit the cpp file.
now i need to create a project,what type should i choose?Win 32 console application?

The header files had been added into the cpp file.
Is there any thing i need to do to add them to the project?

Hi, here is a source file about RFID - VC(exe, header and cpp)
I wanna edit it by VC++ and VS , but it says:

MifareOneDemoDlg.obj : error LNK2001: unresolved external symbol "public: virtual...

How can i set the Baud using DeviceIOcontrol?

BOOL WINAPI DeviceIoControl(
__in HANDLE hDevice,
__in DWORD dwIoControlCode,
__in_opt LPVOID lpInBuffer,
__in ...

i set that using "BuildCommDCB",is it ok?

hi, i found some included APIs, i tried use it ,no compile errors and run time errors, but finally the console just crashed.
Even if i compile without those API, the writfile and readfile ...

Ok, but i have to go now, i will post it ASAP,thanks

hi , good news here.i opened the COM port already.

That' sounds a quite...

Thanks! Do i need to include any header file?

Can you dnowload it?

Sorry,here it is - VC

but now i am using VC to read the mifare.

No. it is just a console application, is it possible to achieve my idea?
you meant the software i used? that is VC++ 6.0.

Cool, thank you so much!

Actually...i started with nothing(about serial port), i am learning the knowledge of microcontroller(A set of kit), but that is another subject, the RFID i used is a...

you surprise me as you have some expriecnce about that!
I can see a light in front of me, haha.

Seriously, the thing i need to do first is to learn the knowledge of serial port...

It 's made by this manufacturer .
My model is MF800

no...i may do that if i really no ideas at the end.

NO, that comes with the device.
it provides checking connection ,reading and writing function, no other further usage.

Thank for your advice!
I try to post a part of code and more informations for your reference.
Thank again.

i have been trying..but there are many classes and header files.
i will try my best to understand what they mean.
