Need help hashing out an error message.

I have created a txt file in order to pull information for this program.

This is the error code I am getting:

c:\documents and settings\administrator\my documents\visual studio 2005\projects\payroll47\test1.cpp(63) : error C2660: 'fopen_s' : function does not take 2 arguments
Generating Code...

Build log was saved at "file://c:\Documents and Settings\Administrator\My Documents\Visual Studio 2005\Projects\payroll47\Debug\BuildLog.htm"
payroll47 - 2 error(s), 0 warning(s)
==

This is the code lines before 63 and after 63 please help:

Code:

//Statements
	printf("Employee files and payroll register\n");
//Line 63----------------------------------------------------------------------below		if ((spEmployeeData =fopen_s    "EmployeeDataFile.txt", "a"))== NULL)
		{
			printf("\aError opening EmployeeDataFile\n");
			return 100;
		} // if open input

If the error message had said "Your shoe is untied," would you bother to check your shoe?

Just like brewbuck, I find that this error message is fairly clear:

Which part of it is that you don't understand.

Please help me understand
"EmployeeDateFile.txt" - names the file to be referenced, "r" -references the mode code.

My question is what are the 2 arguements the error message is referencing.

brewbuck please give me a break I'm still a beginner and don't know everything. Still learning and of course I would check my shoe but what if I didn't know where to find the shoe?

Code:

printf("Employee files and payroll register\n");
		if ((spEmployeeData = fopen_s ("EmployeeDataFile.txt", "r"))== NULL)
		{
			printf("\aError opening EmployeeDataFile\n");
			return 100;
		} // if open input

all good if you know where to find the shoe. I'm not sure what the error message is refering to as the argument because I thought that the filename and the mode where needed parts of the code??

And yet the error message is saying that this function does not take 2 arguments. Maybe it takes only 1, maybe it takes 3, who knows. I have no idea what "fopen_s()" is. fopen() is a standard function, fopen_s() is... I have no idea.

My question is what are the 2 arguements the error message is referencing.

The filename and the mode. Go find the documentation on this fopen_s() thing.

Code:

printf("Employee files and payroll register\n");
		if ((spEmployeeData = fopen_s ("EmployeeDataFile.txt", "r"))== NULL)
		{
			printf("\aError opening EmployeeDataFile\n");
			return 100;
		} // if open input

here is the code if I give you more of the could would you be better able to help?

Seeing the definition of this fopen_s() function would help.

Code:

 the following information: 
		a. Employee number (left-justifed)
		b. Department
		c. Pay rate
		d. Exempt
		e. Hours worked

#include <stdlib.h>

		while (getEmployData (spEmployeeData, &employNum, &depart, &payRate,

				payrollReg (spEmployeeData, employNum, depart, payRate, exempt,
					hourWork, payCheck);
			}// while

		fclose(spEmployeeData);

		return 0;
}//main

I do appreiciate any insight you might be able to share with me. Please guide me I'm not looking for someone to write the code just enlighten my vision. I am either not understanding something or am lost all together.

Thanks

This code still doesn't explain what fopen_s() is. Why are you calling that instead of regular fopen()?

Because when I use fopen() the compiler gives me this error.

My errors are reduced to one with a warning. This is why I'm confused.

fopen_s takes 3 parameters, as defined on the MSDN web-page here:

Matsp,

How might I adjust this program so that I would not need fopen_s, because I am unsure of how to draw on the third parameter required by fopen_s?

Put this line right at the start of your source file

#define _CRT_SECURE_NO_DEPRECATE

If you have many source files, you can do this inside the project as well. Just goto
project->settings->pre-processor
and add that symbol.

Then you can forget all about M$'s attempts to rewrite the standard and use the normal portable functions which everyone else uses, like fopen()

Yes, I agree with this.
