Many tabs using one serial port

[chauteen]

Hi, I'm writing a dialog by MFC. I have several tabs, and every tab has some control items on it. I creat classes for every tab. I want to send out status thru RS-232, such as when the user click one spin, and the spin value will be sent out thru RS-232. My problem is I've got the tab class and a serial class ready. But how to confige a serial port that can be used by "all" tabs. If I create the port in one tab's cpp, other tabs will not be able to use the port, of course. However, it doesn't work if I configure a port in the project's main cpp, either. Forthermore, if I call the functions in the CSerailPort class, like: CSerialPort::Openport("com4"); The compiler says another error: illegal call of non-static member function. Thanx your help.

Buddy, if you are comfortable with pointer,then declare the pointer in base of CSerialPort like this is you class. sorry i didn't work on tab control but i worked on property pages.i think you taleneted enough to understand this. here is little solution, you base class CSerialPort *BasePort; in your tabbed dialog classes as there can be many CSerialPort *DerPort; inbase class contructor or initdialog BasePort=new CSerialPort; // function regrading insilization of port /// now you are creating tab contral, just pass the pointer to every derived tab classes like this. Let One of tab class is Ctab1; now, Ctab1.DerPort=this->BasePort; andthis way you can access teh serial port in nay class. ps,don't forget to delete the pointer before closing the application ----------------------------- "I Think It will Work" Formerly Known As "Alok The Programmer" at CP ----------------------------- Alok Gupta visit me at http://www.thisisalok.tk
