WTL Hello World

构建最简单的WTL Hello World程序，基于：WTL91_5321_Final + VS2013 + WIN7

添加->新建项目

为了简单起见，我们删除一些button和对应的处理代码(一般我们只需要修改dialog对应的.h/.cpp代码)

MainDlg.h

// MainDlg.h : interface of the CMainDlg class
//
/////////////////////////////////////////////////////////////////////////////

#pragma once

class CMainDlg : public CDialogImpl<CMainDlg>
{
public:
	enum { IDD = IDD_MAINDLG };

	BEGIN_MSG_MAP(CMainDlg)
		MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog)
		COMMAND_ID_HANDLER(IDCANCEL, OnCancel)
	END_MSG_MAP()

// Handler prototypes (uncomment arguments if needed):
//	LRESULT MessageHandler(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
//	LRESULT CommandHandler(WORD /*wNotifyCode*/, WORD /*wID*/, HWND /*hWndCtl*/, BOOL& /*bHandled*/)
//	LRESULT NotifyHandler(int /*idCtrl*/, LPNMHDR /*pnmh*/, BOOL& /*bHandled*/)

	LRESULT OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/);
	LRESULT OnCancel(WORD /*wNotifyCode*/, WORD wID, HWND /*hWndCtl*/, BOOL& /*bHandled*/);
};

MainDlg.cpp

// MainDlg.cpp : implementation of the CMainDlg class
//
/////////////////////////////////////////////////////////////////////////////

#include "stdafx.h"
#include "resource.h"

#include "MainDlg.h"

LRESULT CMainDlg::OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
{
	// center the dialog on the screen
	CenterWindow();

	// set icons
	HICON hIcon = AtlLoadIconImage(IDR_MAINFRAME, LR_DEFAULTCOLOR, ::GetSystemMetrics(SM_CXICON), ::GetSystemMetrics(SM_CYICON));
	SetIcon(hIcon, TRUE);
	HICON hIconSmall = AtlLoadIconImage(IDR_MAINFRAME, LR_DEFAULTCOLOR, ::GetSystemMetrics(SM_CXSMICON), ::GetSystemMetrics(SM_CYSMICON));
	SetIcon(hIconSmall, FALSE);

	return TRUE;
}

LRESULT CMainDlg::OnCancel(WORD /*wNotifyCode*/, WORD wID, HWND /*hWndCtl*/, BOOL& /*bHandled*/)
{
	EndDialog(wID);
	return 0;
}

最初的运行样子：

我们新建一个Static Text

我们可以直接在Caption属性修改成我们想要的文字

或者在OnInitDialog编码实现：

CWindow wnd = this->GetDlgItem(IDC_STATIC);
	CStatic *pEdit = (CStatic*)&wnd;
	pEdit->SetWindowText(_T("Hello World"));

更改字体：

	CFont font;
	font.CreatePointFont(16, TEXT("Arial"));

	CWindow wnd = this->GetDlgItem(IDC_STATIC);
	CStatic *pEdit = (CStatic*)&wnd;

	pEdit->SetFont(font);
	pEdit->SetWindowText(_T("Hello World"));
