    Exclamation MFC GUI-setting COMPort and read hex data from pic (ASCII)

    I want to setup my MFC-based dialogue "IDD_LOADCELL" with serial communication so that when that dialogue is pop up, the data from PIC (external device) which is in hex file format is display on the edit control box on the dialogue. The variable name of the edit control box is "m_loadP "and "m_loadT1". type of variable for both are string. I want to get the code for the COMPort setting and reading the data from pic and finally display it on the edit control box created on the dialogue

    Well, you have to read/understand how serial communications work in Windows.
    Then implementing something similar to Serial Port I/O would be a good start!

    What "why"?
    Just add the classes from this essay to your project...

    Note that you also will need to properly set the DCB and Timeouts, See SetCommState function, SetCommTimeouts function

    I'm still confusing about DCB setting... is it like a variable that need to add up in the front line of the name of the COMPort configuration? example like m_dcb.Baudrate..m_dcb.Parity..? what is the usage? I have see a lot of COMPort configuration wwithout the DCB term... Is it specialize for reading hex file?

    Are they not included by default?
    Besides, please read About Communications Resources in MSDN.
