[maypai37]

simple vc++ code copied from book, computing of numerical method using vc++ by
Salleh; chapter 3;
Code3A.h, Code3A.cpp
-------------
tested on my visual studio 2017 enterprize, 15.8.7(I instlalled all vc++, MFC,
c++ game related packags)
--------
incomplete type is not allowed, afxrendertarget.h 348

please help (that code can be find in web easily)

thanks a lot in advance

Identify the type that it says is incomplete.

write class <the_type>; somewhere at the top of afxrendertarget.h, and save it

[maypai37]

is you mean to search string, afxrendertarget.h,
from whole C directory?

I tried indexing Options,

I can not get files included (it keep search indexing,; keep blank in both fields
below)
-------------
#include <afxwin.h>

class CCode3AA : public CFrameWnd
{

public:
CCode3AA();
~CCode3AA();
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP()
};
class CMyWinApp : public CWinApp
{
public:
virtual BOOL InitInstance();

};



-----------
#include "Code3AA.h"
CMyWinApp MyApplication;
BOOL CMyWinApp::InitInstance()
{
CCode3AA* pFrame = new CCode3AA;
m_pMainWnd = pFrame;
pFrame->ShowWindow(SW_SHOW);
pFrame->UpdateWindow();
return TRUE;
}

BEGIN_MESSAGE_MAP(CCode3AA,CFrameWnd)
ON_WM_PAINT()
END_MESSAGE_MAP()

CCode3AA::CCode3AA()
{
Create(NULL, "Code3A: The Skeleton Program",
WS_OVERLAPPEDWINDOW, CRect(0, 0, 400, 200), NULL);
}

CCode3AA::~CCode3AA()
{
}
void CCode3AA::OnPaint()
{
CPaintDC dc(this);
dc.TextOut(100, 30, "Welcome to Windows...");
}
---------------------------------------------------------------------------------
I install all packages from launch/modify for my 2017 visual studio Enterprize.
still got same error at build

actually when I build/compile, there are many errors , many related with these class name,
CD2D, in addition to as (type incomplete is no allowed)

hope to see any advanced help again soon

The original error message suggested that the incomplete class was on line 348.

[1vRz3TCk]

maypai37, what steps did you take to setup the project? Code3A.h and Code3A.cpp are fairly useless on their own.

Edit:
Found the book online, could follow the instructions with VS2010 but not with VS2017... I think I'm now where you are...

My guess at the moment (Haven't used MFC for a while) is that Microsoft have changed/added to the graphic subsystem. The code from the book looks like it is expecting GDI and VS2017 looks like it is using Direct2D.

[maypai37]

348 CD2DResource(CRenderTarget* pParentTarget, BOOL bAutoDestroy);

-------------
please help for what's wrong about that. (really, this is Microsoft programmer's job, not mine)

---------------------
I choose .net frame work at vc++

then Empty project

then
I just type in everything as book listed(in my previous post)

in my 2017 visual studio enterprise.

---------------
I will try to find web, whether is/are good book/ref to learn vc++ graphic through visual studio 2017; in addition to old book I use or tested now.

so, if you have good resource, would you please to share some to me?

[1vRz3TCk]

I think if you can find the recipe for creating a skeletal MFC app, you might be fine with that book. If I get time, I'll have a look and try to workout what the bare minimum version currently is...unless there is someone here who can shed some light.

As for good resources...I usually start with Microsoft documentation...can be hard work but the info is usually there.
https://docs.microsoft.com/en-us/windows/

I haven't seen a good book on programming Windows with C++ for many a year, I haven't been looking too hard.
