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 onceclass 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 screenCenterWindow();// set iconsHICON 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"));
