Hello
I want to send something trough IR port to a printer but I have a
problem .... Just take a look please....
I have a class "Cir"
/*************************************************************/

And a simple form whith a button: (Cir m_serial)
/*************************************************************/
bool CMain::OnP1Button()

char szSmallFonts[] = {0x1B, 0x0F, 0};

char szHighSpeedDraft[4] = {0x1B,0x73,0x30,0};
m_serial.Write( szSmallFonts, strlen(szHighSpeedDraft));
CString szPrinterLine =
"28356349027623498582582346589723456234856823465823450834657893468562348
5689238974365893489";
long lb = m_serial.Write( (char*)szPrinterLine,
szPrinterLine.GetLength() );
if (lb==-1)
{
MSG_INFO("NOTHING");
}
else
{
char szbuff[100];
strcpy(szbuff, "bytes: ");
strcat(szbuff, ftoa(lb,false,0));
MSG_INFO(szbuff);
}
while(m_serial.CheckSendBuffer()!=0){}
m_serial.Close();
return true;
}
What is wrong?
Thanck's in advance
