Bah... I can't bear MSVC++ 7.0...

[Miah]

I seem to be having some major issues with MSVC++, or at least the new version. Is seems that no matter what I do, I just can't make it do really really simple things, such as...

Code: Select all

#include <iostream.h>

main()
{
     cout<<"Hello World!\n";
     return 0;
}

But here's the kicker. I convert something much more advanced to 7.0, such as this here program that makes the Juila Set, and for some reason, it works like a charm.

I got to thinking that maybe I have to do something special to the files to make the simple DOS programs work, as that program isn't the only one that will compile, and that runs in windows. It's only the crap programs I'm having issues with.

Does anyone else expreience these issues?

C++ depricates the .h in the header file.  The new versions of MSVC don't support it at all.  Remove the ".h" and you should be good.  Anyway you should be getting some errors which tell you something to this effect.

[Miah]

That would explain some things... but here's the other issue.

I start a new project, and all sorts of crap is already there...

Code: Select all

// test.cpp : Defines the entry point for the application.
//

#include "stdafx.h"
#include "test.h"
#define MAX_LOADSTRING 100

// Global Variables:
HINSTANCE hInst;// current instance

// Forward declarations of functions included in this code module:
ATOMMyRegisterClass(HINSTANCE hInstance);
BOOLInitInstance(HINSTANCE, int);
LRESULT CALLBACKWndProc(HWND, UINT, WPARAM, LPARAM);

                     HINSTANCE hPrevInstance,

// Initialize global strings
LoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
LoadString(hInstance, IDC_TEST, szWindowClass, MAX_LOADSTRING);
MyRegisterClass(hInstance);

// Perform application initialization:
if (!InitInstance (hInstance, nCmdShow))
{
return FALSE;
}

hAccelTable = LoadAccelerators(hInstance, (LPCTSTR)IDC_TEST);

// Main message loop:
while (GetMessage(&msg, NULL, 0, 0))

What is this for? I just want a simple program...

You are starting a Win32 program, not a console program.  You should also just start an empty project if you don't want to have all the default stuff added.

[Miah]

Hmm... that would do it...

Thanks Dr Know.

Leaving the 'int' return type off main would do it.

And the program you posted later on is an MFC app. Don't use MFC, it's terribly bloated.

[Spectere_uplink]

To create a non-MFC app in MSVC++ 7, click on "application settings" on the wizard screen and it'll give you some more options.  That took me a while to figure out.  I dunno.  Buttons and tabs must be OMFG TOO UG-LAY for Microsoft to use.

Also, yes, leaving off the int in a C++ compiler will give you compiler errors.  Also, Dr Know, the ".h" includes for iostream and other std namespace libraries still exist in MSVC++ 7, they just generate compiler warnings when used (and probably don't exist at all in .NET 2003).
