Help with my application's user defined configuration

Schmoopsiepoo (7)
I am currently writing code for my application's user defined configuration.

The "WriteConfiguration()" function takes two arguments; The setting to be changed, and the new value for the setting. During the execution of this function, the file is opened and loaded into a buffer. The buffer is then passed to another function where each setting is separated into a new row in the Data[][] array. Further separation of the array separates each individual setting from it's value. Once the setting from the "WriteConfiguration()" argument is found, the corresponding value is replaced with the new one. All of the loaded settings in the Data[][] array are then placed in a new buffer and written to the configuration file.

Upon execution of the "WriteConfiguration()" function, I recieve the error:

Unhandled exception at 0x77b615de in WebClient2.exe: 0x00000000: The operation completed successfully.

I have also noticed that in the "WriteConfiguration()" function,

Settings.Separation(SettingsFile.Data[c], *"=", false);

when "c = 0;" "cout << Settings.Data[0];" displays nothing.


Here is the source code:
WriteConfiguration();

Can I ask what the asterix in *"=" is for ? I've never seen it before nor can I find documentation on it...

I'm taking a wild guess here:
Change this:
Settings.Separation(SettingsFile.Data[c], *"=", false);
To:
1
2
 
char myChar = *"=";
Settings.Separation(SettingsFile.Data[c], myChar , false);

It's both beautiful and horrific.

"=" is a string literal; it gives a pointer to the first element in a (const) array of char (which in this case contains only a single char).

How do we get what a pointer is pointing at? With the * operator. So *"=" is the char =.

The more traditional way to have the char = would be '='.

Here's some example code showing this:

#include <iostream>

using namespace std;

int main()
{
  char array[2];
  
  array[1] = 0;
  array[0] = 'b'; // The more traditional way
  
  cout << array << endl;
  
  char x = *"r"; // Both hideous and beautiful. Ah, C.
  array[0] = x;
  cout << array; 
}

Thanks Moschops, indeed it is both hideous and beautiful ~~~

Why on earth would you ever do this? Other than to be obscure

Old C habit? Which reminds me, what is with the brackets and indentation usage? What style/language is that from, I've never seen it written like that before.

Because you're so phreaking leet! Yeah!

It is just my own personal style for organizing code. I am self taught and have not received any formal teachings.

Gotta love C. :3

I was wondering since I personally found it hard to read. Over the years I've switched styles, mainly start with Stroustrup's style, then moved to the JAVA style. It's more important that you can understand than others, but it does help when others can read it just as easily.

As for displaying an empty line, have you verified that the file doesn't contain a blank starting line? Or maybe a line that isn't read properly; ie it has a special character in it that the program doesn't recognize?

That's my only thought, and I looked through the code but nothing really pops out at me. Best of luck.

After switching to "Release" mode in Visual Studio 2010, the problem seized to occur and the operation completed successfully. This is quite strange. Should I worry about this? Is the compiler at fault or is there possibly something wrong with my code that is only discovered in debug mode?

I do know there is a difference between the release bins and the debug bins, but I've personally never encountered an issue with it. Maybe it's an IDE issue?
