Thank you very much,

Take a look at InnoSetup[^] (it's free).

Hi,

Will it support for Visual Studio 2005?

Thanks & Regards

Anitha

You did not even click on the link provided, did you? Inno works as a stand alone utility and has nothing to do with VS 2005.

Thanks..... now i got it.

hi i have written the following code to receive data from mobile using bluetooth through serial communication.

but it is not working

<code>
#include <stdio.h>
#include <conio.h>
#include <windows.h>

#include "stdafx.h"
#include "bluetoothConnection.h"

bool BluetoothConnection::openPort(char *portNum)
{
if (portNum != NULL)
{
hcomm = CreateFile((LPCWSTR)portNum, GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, NULL, 0);
if (hcomm == INVALID_HANDLE_VALUE)
{
return false;
}
else
{
return true;
}
}
else
{
return false;
}
}

bool BluetoothConnection::initPort()
{
dcb.fOutxCtsFlow = false;
dcb.fOutxDsrFlow = false;
dcb.fDtrControl = DTR_CONTROL_DISABLE;
dcb.fOutX = false;
dcb.fInX = false;
dcb.fRtsControl = RTS_CONTROL_DISABLE;

//time settings
timeouts.ReadIntervalTimeout = 20;
timeouts.ReadTotalTimeoutMultiplier = 10;
timeouts.ReadTotalTimeoutConstant = 100;
if (!SetCommTimeouts(hcomm, &timeouts))
{
return false;
}
else
{
return true;
}
}

void BluetoothConnection::ReadPort()
{
memset(chRead, '\x91', 250);
Sleep(1000L);
ReadFile(hcomm, chRead, 250, &dwRead, NULL);
}

void BluetoothConnection::display()
{
printf("%s\n", chRead);
}
int main()
{
BluetoothConnection *bth1 = new BluetoothConnection();
if (bth1 != NULL)
{
if (bth1->openPort("COM4"))
{
if (bth1->initPort())
{
bth1->ReadPort();
printf("the data from com4 is ....\n");
bth1->display();
}
else
{
printf("fail in init\n");
}
}
else
{
printf("unable to connect\n");
}

}
else
{
printf("unable to connect failed in initial state\n");
}
Sleep(1000L);
return 0;
}
</code>

its failing in CreateFile function coz its returns 0xffffff..

can this code be used for bluetooth coz i found such code for serial port comm and infrared.

is there any configurations between mobile and pc before running this application if there please provide me the steps..

First, are you sure the COM4 port exist ? Are you developping for winCE ? If yes, then if I remember well, you have to append a ':' after the port name (thus "COM4:"). Not sure anymore, try it and tell me if it works.

no i am a begginer and i used AT command to test a while long back but now i dont remember it plz.. which is the command to type in and check for the status... and one thing when i open hyperterminal and select com4 and try to type some thing then my mobile disconnects the bluetooth connection...

Hello everyone,

In ATL wizard to create a coclass, under COM category there is an item named "Type", for example, if we assign the short name under C++ category to "aaaa", the value of "Type" is "aaaa Class".

My question is, what is the function of the so-called "Type" and how will client or COM server use this value?

thanks in advance,

By following any one of the hundreds of examples that exist out there for this problem.

Or you could just sub-class the static and give it new behaviours so that (a) it's underlined, (b) has a different cursor (c) has a different colour (d) changes colour once visited (e) performs the desired action upon WM_LBUTTONUP, so long as it was under the mouse when the WM_LBUTTONDOWN message came in.

Remember, google is your friend. (Also, I believe Chris has written an article & class for this)

If possible please explain me with example.

thanks in advance.

I haven't gone through the code for the link that I provided you. but the article writer must have used ShellExecute or something like that to help the user navigate to a URL on which he/she clicks. You can replace this code with creation/showing of a dialog

Hi All

How can i read and write in .txt file in VC++(MFC)?Plz help me

Hi,

You can use CFile, like this you open the file..

char* pszFileName = "c:\\test\\myfile.dat";
CFile myFile;
CFileException fileException;

if ( !myFile.Open( pszFileName, CFile::modeCreate |   
          CFile::modeReadWrite, &fileException ) )

like this you can read and write..

char      szBuffer[256]; 
UINT      nActual = 0; 
CFile myFile;

myFile.Write( szBuffer, sizeof( szBuffer ) ); 
myFile.Seek( 0, CFile::begin );
nActual = myFile.Read( szBuffer, sizeof( szBuffer ) );

Like this you close the file..

myFile.Close();

The price of anything is the amount of life you exchange for it.

Thanks and Regards.
