Oct 24, 2019 Precompiled Header Files.; 13 minutes to read; In this article. When you create a new project in Visual Studio, a precompiled header file named pch.h is added to the project. (In Visual Studio 2017 and earlier, the file was called stdafx.h.)The. Because stdafx.h is different for each project. As you quoted, #include ' searches the path of the current project, and this is where stdafx.h is located. Using #include stdafx.h would be a huge mistake, because it would have to be in the library path (where all the standard library headers are located).
The “stdafx.h” header must be the very first one to be included into the.c/.cpp file. This is obligatory! Otherwise you are guaranteed to get compilation errors. It really makes sense, if you think about it. When the “stdafx.h” file is included in the very beginning, you can substitute an already preprocessed text into the file. Mar 03, 2017 我运用DEV-C 编写程序,在#includestdafx.h这里报错 下面就是我的程序,如果加上 #includestdafx.h 显示 Error stdafx.h: No such file or directory 但是去掉的话,全篇程序都会出现问题,望大家给我指导一下,谢谢。.
So, I'm making the jump from console C++ to Windows programs, and actually having a lot of fun with that! But my method is, to use my Beginner's edition VC++ to compose the program, and when it's 'done', I switch to the free Bloodshed Dev C++ compiler (because the VC always puts that annoying dialog box you have to dismiss before the program will run, the one that says you can't release your program to the public, end-user-liscence blah,blah). Traktor pro 3 with audio 8.
Usually, I manage OK with finishing a project in Dev that started in VC, but this time I have a dialog-based program that includes <stdafx.h>, which in turn includes five other afx*.h files, too.
Dev C++ throws a fit about this. Even after I copied every relevent header over to the Dev C++'s Include directory, it STILL complains that it can't find the headers!
Clue #1: This application used MFC wizard alot while it was a Microsoft project. Handy for adding all those bells and whistles, but does that doom it as far as Dev C++ is concerned?
Clue #2: I have noticed multiple repeat includes in different files of the project. Microsoft seemed happy with that, and I assumed everything was guarded by #ifndef statements. But do they only work for Visual C++?

Someone told me once, 'Just wait until you get linker errors!' I see what he was talking about, now..

Hi I wrote some code but it's giving me error and I have no idea how to fix it. Can you guys help me?
when trying to compile it gives off || Build: Debug in menu (compiler: GNU GCC Compiler) |
C:Usershappyboy9505Desktopmenumain.cpp|1|fatal error: stdafx.h: No such file or directory|
|| Build failed: 1 error(s), 0 warning(s) (0 minute(s), 0 second(s)) |
My code is following.
#include 'stdafx.h'
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
using namespace std;
void show()
{
string file_nm;
cout << 'Enter file name : ';
cin >> file_nm;
ifstream inFile;
inFile.open (file_nm);
char inString[1000];
if (inFile.good())
{
while(!inFile.eof())
{
inFile.getline(inString,256);
cout << inString;
cout << 'n';
}
inFile.close();
cout << 'n';
}
else
{
cout<< 'File does not exit..!';
cout<< 'nn';
inFile.close();
}
}
void add()
{
string txt, file_nm;
cout << 'Enter file name : ';

cout << 'Enter text to be added : ';
cin>> txt;
std::ofstream outfile;
outfile.open(file_nm, std::ios_base::app);
outfile << txt << endl;
}

while(1)
{
cout << 'Main menun';
cout << ' 1) Show a listn';
cout << ' 2) Add a namen';
cout << ' 3) exitn';
cin >> iOption;
switch(iOption)
{
case 1: show(); continue;
case 2: add(); continue;
case 3: exit(1);
default: cout << 'Invalid option..!nn';
}
}
return 0;
}
thanks!
