problem with setting pch file - C / C++ / MFC Discussion Boards

Try using the SetFilePosition(...) function to set the "file pointer", which is the location you are reading/writing from, to the end of the file before writing to it.

dwPtr = SetFilePointer (hFile, lDistance, NULL, FILE_END) ;

Yes, this would work. Would the SetFilePointer() function be used to replace the \r\n ??

Thanx for the response.

   No. The \r\n just indicates (in a MSDOS-style text file) the end of a line. That has nothing to do with where in the file you are currently writing at.

   Think of the file like a piece of paper - after getting it, you have to decide where to start writing on it. You can either write on top of other stuff that is already there, or move to the end where there is empty space.

   Peace!

This works .... Jig | [Dance]

hFile = CreateFile(TEXT("C:\\testing.txt"),
			FILE_APPEND_DATA,
			FILE_SHARE_READ,
			NULL,
			OPEN_ALWAYS,
			FILE_ATTRIBUTE_NORMAL,
			NULL);

Why go to the trouble of using CreateFile directly? Using the standard library it's as simple as this:

// AppendFile.cpp : Defines the entry point for the console application.
//
 
#include "stdafx.h"
#include <fstream>
 
int main()
{
	using namespace std;
 
	ofstream of("C:\\Users\\Steve\\out.txt", ios::out | ios::app);
	of << "Appended me\n";
 
	return 0;
}

   You are missing one or more required files.

   Having an error about a missing PCH file is due to a build issue. Missing an .H file is a missing file.

Hi All .

In GPU & CUDA programming : What is difference between shader clock and core clock ?
thanks .

different parts of the GPU run at different clock speeds.

the core clock controls the basic functions. the memory clock regulates memory access. the shader clock controls the speed of the shading section.

Google should be able to tell you more.

   Depends on what you are really asking... What do you mean by "System Time"? Do you mean the current time as far as the system is concerned? Or do you need to know how long the system has been running?

   Do you also need millsecond resolution (where you need a feature that has millisecond resolution), or just need the results in milliseconds (where you can simply multiply a seconds value by 1000)?

   Either way, a simple search in MSDN will provide useful results.

   Peace!

Link L;ist in C++.NET

Hi all,
I am starting with a contact manager application. And for this i need to have a double link list to get the data from the csv file.
So that i can add new contact, delete contacts, update contact and save contact.
Is linklist and node class already there in C++.NET
or do i have to create one.
And one more thing i would like to ask is do i have to sort the list before i can read it (using doubly linked list). I mean do i have to write a sort function. Which sort method would be best for this application ?
Thanks a lot

sir, you've been asking for C++.NET several times already, and you've been said that this was probably refering to something different to what you think.

that's why, before someone else propose a solution, I'd like you to tell me what you mean exactly by C++.NET ?

thanks

what do you want to know about C++.NET. It is C++ language based over .NET framework.
Which is bit different from VC++ or C++(Borland)
In Borland you have to write your own classes for mostly everything. But in .NET few classes are already defined.
So my question was whether link list class is already there in MS Visual Studio C++.NET 2005 or not.
Thanks

so that's what i thought.

Microsoft's C++ extension to the .NET framework is called Managed C++ (or C++/CLI for newer versions).

questions related to it belongs to the Managed C++/CLI Forum[^]
