Hello,

Finally I am down to the last issue with my program: text file writing and reading.

My file has a function whose ofstream object does work and produces a text file for printing called "print".
This function is the printTextFile(fstream &readFromFile ) function.

But initially it is supposed to be creating a file called "hardware"where I store the records, update the records, add a new record, or delete. Well it seems that the fstream objects here are not working because when I search my file for hardware I cannot find it. I am trying to summarize my functions below with their objects and then including my main() and as well the functions and the function definitions.

createAndInitializeTextFile() - ofstream object that writes
enterRecords() - fstream object that I use to seek records with seekp and then also use to write

processChoice() has the fstream object with hardware.dat that is passed the following functions:

void printTextFile(fstream&);
void updateRecord(fstream&);
void newRecord( fstream& );
void deleteRecord( fstream& );
void outputLine( ostream&, const Tools & );

My code in main() :

int main()
{
	Tools tool;
	tool.createAndInitializeTextFile();
	tool.enterRecords();	

	if(tool.test())
	{
		cout << "\nHardware program successful.\n";		
		tool.processChoice();
	}
	else
	{
		cout <<"\nHardware program failed.\n";
	}

	cout << endl;
	return 0;
}

My member function definitions:

void Tools::createAndInitializeTextFile()
{
   ofstream outTools( "hardware.dat", ios::out | ios::binary );

   // exit program if ofstream could not open file
    if ( !outTools )
   {
        cerr << "File could not be opened." << endl;
        exit( 1 );
   } 

   Tools blankTool(0); // constructor zeros out each data member

   // output 100 blank records to file
   for ( int i = 0; i < 100; i++ )
      outTools.write( reinterpret_cast < const char * >( &blankTool ), sizeof ( Tools ) );    
}

void Tools::enterRecords()
{
    fstream outTools( "hardware.dat", ios::in | ios::out | ios::binary );

    // exit program if fstream cannot open file
    if ( !outTools )
    {
       cerr << "File could not be opened." << endl;
       exit( 1 );
    } // end if

       tool.setToolName( toolName );
       tool.setInStock( inStock );

Well, it seems you have a problem.
This is not enough: what and where is a problem?..

Well, it seems you have a problem.
This is not enough: what and where is a problem?..

I can't find my hardware.dat file on the computer and also the write in the updateRecord() function does not work.

>>I can't find my hardware.dat file on the compute
It will be in the same directory that contains the program *.exe file.


>>the write in the updateRecord() function does not work.
what makes you think it doesn't work? What does it do that it's not supposed to do, or what doesn't it do that its supposed to do ? Just by looking at the function it appears to be working right, but since we don't have all the code for the entire program its not possible for us to test it.

Basically I typed in the input and then hit 1 to print the file. I can find the print.dat file but I cannot find the hardware.dat.

Basically I try to make a change and then hit 1 again and when I go back to check the print.dat it shows it in the output screen but then hit 1 again and there is no change, the change also does NOT occur in the print.dat. So when I could not find the hardware.dat this makes me think that I am not recording there to begin with.

You apparently didn't get a clean compile with the code you posed because it contains several errors. One error is function outputLine() -- One place passes fstream object as the first parameter while another passes ofstream. If I leave it as ostream like you have it then the function has millions of errors. My suggestion is to NOT use ofstream, but use fstream everywhere so that your program is consistent.
