I'm trying to use _strnextc from C Run-Time Library in Visual C++ v6 code, but compiler says is undeclared - I have included the relevant .h file, but looks like something isn't getting #defined to access this function. I am building a statically linked single threaded MFC ptroject.
Can anyone help ?
Thanks,
Grant.

Hi ,
I am totally new to VC++ .NET environment.
My application is of 3 parts; a static library built in VC++ 6, the application exe - a VC++6 console application and a MFC Extension DLL again from VC6. But all these I have included in VC.NET solution. The static library is used by both the exe as well as the DLL.
I was forced to convert the DLL to Managed Extension as I was using XMLReader.
As i am using a class declared in the static library in the DLL, i get a linking error:
fl_rule_engine error LNK2020: unresolved token (0A00000C) CBinaryField.__dtor
Any help will be much appreciated!!!
This is my first question and I hope I get some answers.
Thanks

Hi,
I want to read data from serial port asynchronously. I developed a program and I am sending the reading part of that program. When I build this code, I have not met any error. But, when I run the program and read data from serial port, my program gives unhandled exception error and I can not see any data on my edit box. Anybody else that helps me about this problem?
Thank you,
Semih
The reading part of my program:
#define MAX_BUFF 128
#define TEN_K 10240
#define STRMAX 1024
HANDLE Open_Com;
HANDLE SPEvent;
DCB dcb;
COMMTIMEOUTS CommTimeouts;
OVERLAPPED overlapped;
CWinThread* pComPort;
CSP_AsyncRead_2Dlg *pWnd = ((CSP_AsyncRead_2Dlg*) pComPort);
UINT ReadPort(LPVOID pComPort)
{
BYTE counter=0;
char sMsg[512];
BOOL fSuccess = 0;
DWORD dwEvtMask = 0;
BYTE tmp[16];
int ReadConstant = 1;
Open_Com = CreateFile("COM3",
GENERIC_READ | GENERIC_WRITE, //access (read and write)
0, // 0: cannot share the com port
NULL, // security (None)
OPEN_EXISTING, // creation : open existing
FILE_ATTRIBUTE_NORMAL, // overlapped I/O
NULL); // no templates file for COM port
if (Open_Com == INVALID_HANDLE_VALUE) //check whether the COM port is opened or not
{
AfxMessageBox("Port Acildi");
} // end if (m_hCom == INVALID_HANDLE_VALUE)
if (Open_Com)
{
memset(&dcb,0,sizeof(dcb));
dcb.DCBlength = sizeof ( DCB ) ;
dcb.BaudRate = 9600;
dcb.ByteSize = 8;
dcb.Parity = NOPARITY;
dcb.StopBits = ONESTOPBIT;
SetCommState(Open_Com, &dcb); // guncel dcb sutructure degerlerini yerlestir
SetupComm(Open_Com, MAX_BUFF, MAX_BUFF); // set input and output buffer sizes
fSuccess = SetCommMask (Open_Com, EV_RXCHAR | EV_RXFLAG); // Set the mask for the events you want to listen for
} // end if (Open_Com)
if(fSuccess)
{
while(Open_Com != INVALID_HANDLE_VALUE)
{
int iBytesRead = 0;
DWORD iBytesReadThisTime = 0;
char szData[MAX_BUFF];
BOOL bRead;
WaitCommEvent(Open_Com, &dwEvtMask, 0);
SetCommMask (Open_Com, EV_RXCHAR);
if (dwEvtMask & EV_RXCHAR){

iBytesRead += iBytesReadThisTime;
}
tmp[iBytesRead] = '\0';
if(tmp[0] != '\0'){

e->Delete();
}

}
} //if(fSuccess)
return 0;

Where is your program crashing ? I suggest you to use the debugger and step into the code to see where it crashes. It is also very usefull to see the variables value.

I always use the debugger to check any errors. In the following, I marked the line where my program is crashing. Please make suggestions that overcome my problem.

The variable name of my edit box. Its category is value and its variable type is CString.
|
|
|
|

 Uuuuhhhh
What's this ???
CWinThread* pComPort;<br />
CSP_AsyncRead_2Dlg *pWnd = ((CSP_AsyncRead_2Dlg*) pComPort);<br />
<br />
...<br />
...<br />
<br />
pWnd->m_Vreaddata.SetAt(counter++,*tmp); <br />
What are you trying to do there ??? You have an unitialized CWinThread pointer that is converted to a CSP_AsyncRead_2Dlg pointer and after that you call a function from this 'pointer' 
First, you cannot convert a CWinThread pointer into a CSP_AsyncRead_2Dlg (they are completely different things) and second your pointer points to unitilazed memory (it hasn't been initialized) and so you cannot use it before make it points to a valid object.

So, how should I change my program? Could you write the correct parts that must be changed in my program?
Gratefully thank you for your help.

If your CSP_AsyncRead_2Dlg* class is the main window of your program and if you use the MFC, you can use AfxGetMainWindow to retrieve a pointer to the main window (then you'll have to cast it to CSP_AsyncRead_2Dlg*).
I also strongly suggest you to get rid of global variables and global functions, preferably make them members of some class.

Does anyone know how to switch the input focus from a console window back to the application window??
I've tried SwitchToThisWindow but it doesn't work.
Is it because i'm calling this in a worker thread function.
UINT MyThreadProc( LPVOID pParam )
{
HWND hwndMain = (AfxGetMainWnd())->GetSafeHwnd();
SwitchToThisWindow(hwndMain, TRUE);
}

What do you mean ? I don't understand your question here. Do you have two separate apps (one a console application and the other a windows application) and inside the console application, you want to set the focus to the other application (that is the window app) ?
If yes, you will need to get the handle with FindWindow function.

No i only have one MFC application.
In the my application i have a DLL statically loaded from which i call a function to invoke a debugging console window.
My application communicates to this console window via tcp.
The console acts is the server and my application acts a client.
Now i want to be able to switch to my main application window where i can pressed a key and send a corresponding debug command to the console window.
But atm as soon as i invoke the console window and establish a server-client connection i can't switch back to the my app window.
The console seems to be waiting to receive some data from my application.
I need to switch to the application so that i can press a key for the client to send a debug command to the console.
