Hello to all.
I'm a "Last-becomers" in VC++.
During my first try using MFC and VC++ ,I found this linker error.
------------------------------------------------------------------------
Linking...
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
---------------------------------------------------------------------
What must I do to solve this problem?
My program isn't an application created by the MFC wizard.
It is small and i post it for let you know the caos that I had create.
-----------------------------------------------------------------------
MyFirst.h
class CMyFirst : public CWinApp
{
public:
virtual BOOL InitInstance();
};
//the window
class CMyMainWnd : public CFrameWnd
{
public:
CMyMainWnd();
protected:
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP();
};
-------------------------------------------------------------------------
MyFirst.cpp
------------------------------------------------------------------------
#include<afxwin.h>
#include"myFirst.h"
CMyFirst first;
BOOL CMyFirst::InitInstance()
{
m_pMainWnd = new CMyMainWnd();
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow();
return true;
}
BEGIN_MESSAGE_MAP(CMyMainWnd,CFrameWnd)
ON_WM_PAINT()
END_MESSAGE_MAP()
CMyMainWnd::CMyMainWnd()
{
Create(NULL, _T("My beautiful application"));
}
void CMyMainWnd::OnPaint()
{
CPaintDC *dc=new CPaintDC(this);
CRect *rect=new CRect();
GetClientRect(rect);
dc->TextOut(30,30, CString (_T("La prima scemenza stucchevole")));
delete dc;
}
----------------------------------------------------------------------
I'm waiting for responses...
Thanks a LOT..

I am not sure which IDE you are using but you need to include nafxcwd.lib in your linker settings. Unresolved external sysmbols come from the linker not being able to find the implementation of the function in the header file.
I am using MSVS 2003. So I go to Project on the file menu then Properties. I then select linker from the listview. Then under general there is an Option for additional Library Directories. Add the path to nafxcwd.lib. This should fix it.
Best of Luck

Micheal Dunn has done a nice job giving answers to FAQ's. Read the C++ forum FAQ[^] and you'll find your answer..
Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

Looks like your linking multi-threaded libraries to a single-threaded app to me...

Since CView is derived from CWnd and your views are derived from CView simply try the GetWindowRect() member of your view class.

I had already used the GetWindowRect() function, But I need to get the Width so that I can display one splitter of 1/4 of the application window and remaining 3/4 for another splitter.

OK !
Assuming rightPane and leftPane are your two view classes in the splitterWnd:
RECT rectAppl;<br />
long heightAppl=0;<br />
long widthAppl=0;<br />
<br />
AfxGetMainWnd()->GetClientRect(&rectAppl);<br />
<br />
heightAppl=rectAppl.bottom-rectAppl.top;<br />
widthAppl=rectAppl.right-rectAppl.left;<br />
<br />
rightPane.SetWindowPos(&wndBottom, 0, 0, widthAppl/4, heightAppl, SWP_NOMOVE|SWP_NOZORDER);<br />
leftPane.SetWindowPos(&wndBottom, 0, 0, (widthAppl/4)*3, heightAppl, SWP_NOMOVE|SWP_NOZORDER);
I think thats what you want to do.

Ok, what exactly did you want to know about message maps in MFC, aside from the framework using them to connect messages and commands to their handler functions.

It helps to be specific the first time around.
See here for an example.

Congratulations on your desire to learn about manipulating Excel files via C++.  What exactly are you having trouble with? What code have you put together thus far?
