Read and write the values into file

[mr.sam1024]

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.

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!
sam.

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.
