Have you looked into the WM_CTLCOLOR message, or the OnCtlColor() handler?

What about overriding PreSubclassWindow() in your derived class and changing the color there?

hi,
I have created a dialog using Cproperty sheet but facing difficulty while setting the focus on Help button from Cancel button and vise-versa using arrow keys, though using tab it works properly. Also, its not using Active Control X.

Need to get Command line argument and add to this simple function

You need to look into the WS_GROUP style.

Hi there!

I'm quite new with C++, using other languages but now i needed to write an Printer USB routine in C++, and i need some help!

It's like this

BytesToWrite = sprintf( (char *) szBuffer, "\033F\r\033B 512 600 4 1 2 3 150 1 999999999\r\033I\r");

WriteFile( hDevice, szBuffer, BytesToWrite, &cbWritten, Null);

etc, etc, etc

I need to replace the 999999999 with the first command line argument (paramstr(1) Can someone help me with this!?

What this function does, is to send ESC commando codes to an Zebra Eltron printer.. Print barcode.. 999999999 is the barcode, but i need be able to call this little application from another application then with the barcode as command line argument.!

Best regards

Does your program have a main() function?

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

Andreas

Command-line arguments are supplied in the argv (argument vector) variable.

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

Okey, so one step further Smile | :)

.. 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]);

Overloading << operator?

Re: Overloading &lt;&lt; operator?

6-Dec-05 2:03

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) ...?
