Hi, yes!
Srry, didn't mention.. but here it comes!
int main(int argc, char* argv[])
{
TCHAR DeviceName[1024];
HANDLE hDevice = NULL;
DWORD cbWritten;
DWORD cbRead;
BYTE szBuffer[1024];
DWORD BytesToWrite;
StringType SlumpNum;
// This function enumerates the printer class devices and detects the appropriate
// device
CCmdLine cmdLine;
EnumeratePrinter(( LPGUID) &GUID_CLASS_ZEBRA_USB,
DeviceName,
PRINTERNAME);
hDevice = CreateFile(DeviceName,
GENERIC_READ | GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
0,
NULL);
// Read Ribbon
BytesToWrite = sprintf( (char *)szBuffer,
"\033!RIBBON\r");
WriteFile( hDevice,
szBuffer,
BytesToWrite,
&cbWritten,
NULL);
// To read you need to send "\033E 2\r"
BytesToWrite = sprintf( (char *)szBuffer,
"\033E 2\r");
WriteFile( hDevice,
szBuffer,
BytesToWrite,
&cbWritten,
NULL);
ReadFile( hDevice,
szBuffer,
1024,
&cbRead,
NULL );
// End of ribbon read
// Start Encode Data
// Fill in the data in firmware buffer
// First track ZEBRA1 command: \033&B 1 ZEBRA1\r
// Second track Age command: \033&B 2 28\r
// Third track YOB command: \033&B 3 1975\r
// Encode all three track
// command: \033E*\r
BytesToWrite = sprintf( (char *)szBuffer,
"\033F\r\033B 512 600 4 1 2 3 150 1 999999999999\r\033I\r");
WriteFile( hDevice,
szBuffer,
BytesToWrite,
&cbWritten,
NULL);
And you can see the 999999999999 that i would like to insert the first command line parameter instead...
Regards

Actually it has nothing to do with C++. See here and here for more.

Okey, so one step further  .. guess i used the argv correct
same as ParamStr in Delphi and so on.
Ok, now i'm having trouble to inserting that string into the function.
Like this, wich doesn't work:
Argument = argv[1];
BytesToWrite = sprintf( (char *)szBuffer,
"\033F\r\033B 512 600 4 1 2 3 150 1 "&Argument&"\r\033I\r");
Thankyou!

Try:
sprintf(szBuffer, "\033F\r\033B 512 600 4 1 2 3 150 1 %s\r\033I\r", argv[1]);

I've tried to overload the << oprator, so that I can output to a file and to a console at the same time but I have no success. I cannot find a solution in Internet and I get the error message: ambigous overload of operator <<...
Any ideas what to do?
I want to be able to use this operator to output something like:
logfile << "data";
but still to be able to do this:
cout << "out";
Thank you!

i'm not sure i understand.
you want - in the same << operation - that your datas are written both in a file and in a console ?
there's no need to overload such an operator for this.
you write a function say writeOutput(data_to_write) in which you perform a cout << data and a file << data where file is an ifstream opened with the file to write...
if not, please explain more clearly...

Yes you are right but I want to be able to use variable number of arguments but I don't want to use va_list, etc... C functions.

I have done it that way but according to samples I've found in Internet, it has to be possible to do it with overloading << but I cannot get it to compile.

any chance to have a look at your "not-compiling" code (i don't want it all, i need only a piece of code to understand how you try to achieve the point we're talking about) ...?

Thank you very much for wanting to help me. The problem is that I've deleted it yesterday and I cannot find it now, although I'm searching it yet for my own needs.
If I find it, I'll post it later.
Thank you!

I don't understand how varargs fits into overloading << ?

It seems that CP likes eating #includes... of course I use: fstream and iostream.

Iam using VC++ as a fonrtend software to communicate with embedded system
through Serial communication(RS-232). Iam using Readfile and Writefile
functions to read and write through COM port. Can anyone Clarify me the
following,
* Is it necessary to Flush the Input and Output buffer for every command
being transmitted/received ???
* If not, how often should i Flush the input and output buffer ???

Hello.
I think you should flush the buffers after every Writefile. Else, chances are that the data will remain in the write buffer. When you do a flush, the data will be sent to the device.
There is (generally) no need for flush before Readfile.
You might considder to search for a serial class. There are several here at CP. I have found them very useful over the years.
