need help in MFC

hi, i have developed console program in C language running fine. the program is used to communicate to a motor through serial port. now i wanted to build GUI in MFC vs2008 (some of which i have completed). i'm facing problem in opening serial port as i have done in console program. can any one tell how to implement console program for opening serial port. code below shows how i open serial port in console program.

int COMportNum, BaudRate;
char COMportName[256], tmpChar;
portstream_fd COMstream;
char COMportPrefix[10] = "COM";

COMportName[0] = ' ';
while (COMportName[0] == ' ') {
printf("\nEnter the %s port number the motor is attached to: ", COMportPrefix);
scanf("%d", &COMportNum);
printf("You selected %s%d. Is this OK? (enter 'y' or 'n'): ", COMportPrefix, COMportNum);
tmpChar = 'f';
while ( (tmpChar != 'y') && (tmpChar != 'n') )
tmpChar = ((char) tolower(getchar()));
if ( tmpChar == 'y' )
sprintf(COMportName, "%s%d", COMportPrefix, COMportNum);
}
tmpChar = 'f';
while (tmpChar != 'y') {
printf("\nEnter the baud rate the motor communicate at (default: 9600): ");
scanf("%d", &BaudRate);
printf("You selected %d. Is this OK? (enter 'y' or 'n'): ", BaudRate);
tmpChar = 'f';
while ( (tmpChar != 'y') && (tmpChar != 'n') )
tmpChar = ((char) tolower(getchar()));
}

 /\* initialize the serial port \*/
 set\_baud\_rate(BaudRate);
 COMstream = open\_host\_port(COMportName);

 if ( COMstream == PORT\_NOT\_OPENED )
     { printf("\\nSerial Port setup error.\\n");
       goto abnormal\_exit;  }
 printf("\\nSerial port %s initialized\\n", COMportName);

You would do exactly the same in the MFC program. You could make your comport handler into a class or add it to one of the existing classes. You then activate it by a menu selector or toolbar button.

can you please send me some reference example sites?

References for what? If you do not understand MFC then a search of The CodeProject Articles[^], MSDN[^] or even Google, will help. Alternatively there are many books on the market.

In a rather rough approach you may let the user write the full name of the serial port into an edit box (say myEditBox) and use that string as argument of open_host_port, that is as simple as (assuming a ANSI build):

CString portname;
myEditBox.GetWindowText(portname);
COMstream = open_host_port(portname);

Veni, vidi, vici.

but open_host_port () is defined as

portstream_fd open_host_port(char *portname)

CPallini

Well, that is a open_host_port fault. Why - the fresh Hell - the function needs a not-const string? However

COMstream = open_host_port((LPSTR)(LPCSTR) testCStr);

should do the trick. BTW I ask you once again (I'm curious): what library are you using?

Veni, vidi, vici.

Compensated for the unwarranted univote.

I wish bleedin' univoters would tell people WHY they do it. Mucking Fuppets. How the hell are we supposed to learn if they won't tell us what we're doing wrong...

Univoters normally include the OP when someone doesn't actually write all their code for them. For some reason, CP forums seem to be seen as the source of free software where you post up a vague problem and miraculously someone will write all your code for you. For free.

Yes, but then they wouldn't be univoters. Quite frankly, I think I'm big enough and ugly enough to take it on the chin. :(( :(( :((

I'm sure you are, still bloody irritating though...

thank you CPallini. that was really helpful.

CPallini

You are welcome.

Ok, take my 1. I can't tell you why I can't tell you why :-D

Veni, vidi, vici.

Yep, but don't tell him! :-)
