Thread: Getting text for editing ...

Hi,

I was wondering if there's a way (and I'm sure there is, but I don't know what it is due to inexperience) open a file with in a program, and to print the text on the screen. This is simple of course, but what I wanted to know is whether there's a way to edit that which was in the file itself withing the console.

We'll say I had a file in the C:\\ drive called test.txt and

Code:

Hi, this is a test!

is written in the file. I know I could simply oped it up from within the program and edit it in whatever automatically opens text documents, and edit it there, but I would like to edit it in the console without having to retype "Hi, this is a test!" and delete most of it in order to change it to "Hi, I hope this works"

Know what I mean?? Twomers

Know what I mean??

Nope.

I belive he wants to open a text file in the msdos window, and being able to edit it there without a text editor.
Pointless to me.

Compiler/OS. You said C:\\ (You should know the \\ is only because you are escaping the character) so I am assuming Windows.

Code:

#include <windows.h>
#include <stdio.h>

void MouseChangeCursorPos(MOUSE_EVENT_RECORD mEr) 
{
	HANDLE hOut;
	COORD cRt;

	if(mEr.dwButtonState == FROM_LEFT_1ST_BUTTON_PRESSED)
	{
		hOut = GetStdHandle(STD_OUTPUT_HANDLE);
		cRt = mEr.dwMousePosition;
		SetConsoleCursorPosition(hOut, cRt);
	}
}
void WriteKey(KEY_EVENT_RECORD kEr) 
{ 
	if(kEr.bKeyDown)
	{
		if(
			kEr.dwControlKeyState != LEFT_ALT_PRESSED &&
			kEr.dwControlKeyState != LEFT_CTRL_PRESSED &&
			kEr.dwControlKeyState != RIGHT_CTRL_PRESSED &&
			kEr.dwControlKeyState != RIGHT_ALT_PRESSED &&
			kEr.dwControlKeyState != SHIFT_PRESSED &&
			kEr.uChar.AsciiChar)
		
		{
			printf("%c", kEr.uChar.AsciiChar);
		}
	}
} 
 
int main(int argc, char *argv[]) 
{ 
	HANDLE hIn; 
	DWORD read, dwOld; 
	INPUT_RECORD irBuf[128];
 
	hIn = GetStdHandle(STD_INPUT_HANDLE);
	GetConsoleMode(hIn, &dwOld);
	SetConsoleMode(hIn, ENABLE_MOUSE_INPUT);

	printf("Hello World!");

	while(true) 
	{
		ReadConsoleInput(hIn, irBuf, 128, &read);
		for (int i = 0; i < read; i++) 
		{
			if(irBuf[i].EventType == KEY_EVENT) 
				WriteKey(irBuf[i].Event.KeyEvent);
			if(irBuf[i].EventType == MOUSE_EVENT) 
				MouseChangeCursorPos(irBuf[i].Event.MouseEvent);
		}
	} 

	SetConsoleMode(hIn, dwOld);	
	return 0; 
}

You can implement bounds checking and delete handling and undo's and all the fancy features of a text editor yourself? You will enjoy these API functions: http://msdn.microsoft.com/library/de..._functions.asp

I think you want fstream.

Tonto: Thanks a lot! that's a cool code, especially when you clock the mouse to where you want to go in the code. I actually found another way of doing it, well it's esentially the same thing to be honest, but without that nifty mouse thing.
