Read and write the values into file

Hi!

Please correct the below code:
file already contains entries : 1st row username; 2nd row password.
check status required to write at third line and need to read or alter the check status value.
Currently this code is working if already there is a value for check status, then it is overwriting else UI hanging.

Code:

---

WriteCheckStatusToFile(BOOL& locVar)               
{       
        FILE *l_pFile = NULL;       
        CString l_strRememberCheck;
        l_strRememberCheck = GetExePath() + _T("password");
       
        CString sVar;
        sVar.Format(_T("%d"),locVar);
        if(NULL != (l_pFile = fopen(l_strRememberCheck, _T("r+"))) )
        {
                int count = 0; 
                char c;         
                while(count != 2)
                { 
                        if((c = fgetc(l_pFile)) == '\n') count++;
                }               
                fseek(l_pFile,ftell(l_pFile),SEEK_SET);                 
                fprintf(l_pFile, sVar);
        }
        l_strRememberCheck.ReleaseBuffer();
        fclose(l_pFile);
}

thanks in advance to all!

You should know about code tags by now.

Since the loop runs while count != 2, and count is incremented only inside an if statement, clearly that if statement condition isn't met twice.
