Yes, something like that. In fact, the expression ret == SQL_SUCCESS 'returns' a boolean (true if they are equals, false if they are different). The same with the || operator. Thus, the complete expression returns a boolean, which is stored in m_bIsConnected.

Maybe by using the correct function ? Use Sleep instead of sleep

Hi all,

I have a binary file. I want to read as it is(i mean ones and zeros), and at the same time need to store in an array. Here is the code I used to read the file.

<br />
ifstream file( "G00046_002_01.srf" ) ; <br />
file >> noskipws ;<br />
typedef bitset< numeric_limits<unsigned char>::digits > bitset ;<br />
unsigned char byte ;<br />
<br />
if(filebin.is_open())<br />
{<br />
	while( file >> byte )<br />
	{<br />
		cout << bitset(byte) ; <br />
		filebin << bitset(byte) ;<br />
	}<br />
	filebin.close() ;<br />
}<br />

Can you guys tell me how store those zeros and ones on an array. I confusing that working with dynamic data and arrays. Tried, but failed.

How to check whether cts pin is on or off using vc++

I have to check whether cts pin is on or off I tried the below code but no use

if(GetCommModemStatus(m_hPort,&dwCommStatus))
{
if(dwCommStatus & MS_CTS_ON)
TRACE("cts on \n");
if(dwCommStatus & MS_DSR_ON)
TRACE("dsr on \n");
if(dwCommStatus & MS_RING_ON)
TRACE("ring on \n");
if(dwCommStatus & MS_RLSD_ON)
TRACE("rlsd on \n");
else
TRACE("pins no response\n");
}

I am getting pins no response.

Any help is welcome

Did you check that your CTS signal is high ? (with a voltmeter or an oscilloscope)

I checked before I connected the serial port cable to my computer.It showed +9v in the voltmeter and then i connected the serial cable but I am not getting any response or value.

Then I don't really see... Are you sure that you the port is opened correctly (with CreateFile) and that you open the same port ?

If I remember right, RS232 uses a voltage feed of +-12V. And I know, from my own experience, that an open connector can give any state, it depends how the hardware is designed.
The question is: Do you get antoher result when you have a negative voltage on the cts pin?

Maybe you can try with a real modem, if you set DTR high/active, then RTS, the modem should respond with setting CTS high/active.

Again, if I remember right, "high/active" really means a negative voltage on the pin in question. But I might be wrong here, so you'd better check that piece of information.

Use accelerator for Ctrl + C. Thus you will get the event (Ctrl+C press) and follow as ThatsAlok said

From within the IDE, press Ctrl+R and select Accelerator from the list of types. Click the New button. Double-click the newly added accelerator item. Check the Ctrl checkbox. Type a C in the Key combobox. Press Enter. You should now have a Ctrl+C accelerator key. Check out the LoadAccelerators() function.

you have to handle WM_KEYDOWN message for ctrl+c and there you have to read the text from listctrl and copy that into clipboard.. which can be copied anywhere using ctrl+ v
