昨晚在另外一篇文章中找到了修改直接给HDC中输出文字的办法了，但是控件的字体一直没法修改，今天搞了一天晚上还是问的以前的同事才搞定。原来发送个消息都好了。直接的源代码看这个把

#include <windows.h><br /> #include <stdlib.h><br /> #include <stdio.h></p> <p>#define BUFFER_SIZE 100<br /> #define TITLE_WARN "警告"<br /> #define TITLE_INFO "提示"</p> <p>#define HB_SEND_SOCKET_ID 0x01</p> <p>TCHAR wzClassName[BUFFER_SIZE] = TEXT("myWndClass");<br /> TCHAR wzWindowName[BUFFER_SIZE] = TEXT("DysNET监控中心");<br /> // 主类声明<br /> WNDCLASS wndclass;<br /> // 按钮控件<br /> HWND hbSendSocket;<br /> // 全局的字体<br /> HFONT hfont;</p> <p>// 初始化窗体<br /> void WINAPI InitWndClass(HINSTANCE hInstance);<br /> // 主回调函数<br /> LRESULT CALLBACK MyWindowProc(<br /> HWND hwnd, // handle to window<br /> UINT uMsg, // message identifier<br /> WPARAM wParam, // first message parameter<br /> LPARAM lParam // second message parameter<br /> );<br /> // 创建组件<br /> void CreateComponent(HWND hwnd, LPARAM lParam);<br /> // 初始化字体<br /> void InitSysFont(void);</p> <p>int WINAPI WinMain(<br /> HINSTANCE hInstance, // handle to current instance<br /> HINSTANCE hPrevInstance, // handle to previous instance<br /> LPSTR lpCmdLine, // command line<br /> int nCmdShow // show state<br /> )<br /> {<br /> // 窗口句柄<br /> HWND hwnd;<br /> // 消息体<br /> MSG msg;</p> <p> InitSysFont();<br /> InitWndClass(hInstance);<br /> RegisterClass(&wndclass);<br /> hwnd = CreateWindow(wzClassName, wzWindowName, WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL);<br /> ShowWindow(hwnd, SW_SHOWDEFAULT);<br /> UpdateWindow(hwnd);<br /> while(GetMessage(&msg, NULL, 0, 0) != 0)<br /> {<br /> TranslateMessage(&msg);<br /> DispatchMessage(&msg);<br /> }<br /> return 0;<br /> }</p> <p>//<br /> // 初始化WNDCLASS类<br /> void WINAPI InitWndClass(HINSTANCE hInstance)<br /> {<br /> wndclass.style = CS_HREDRAW | CS_VREDRAW;<br /> wndclass.lpfnWndProc = MyWindowProc;<br /> wndclass.cbClsExtra = 0;<br /> wndclass.cbWndExtra = 0;<br /> wndclass.hInstance = hInstance;<br /> wndclass.hIcon = LoadIcon(NULL, IDI_WINLOGO);<br /> wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);<br /> wndclass.hbrBackground = (HBRUSH)GetStockObject(ANSI_FIXED_FONT);<br /> wndclass.lpszMenuName = NULL;<br /> wndclass.lpszClassName = wzClassName;<br /> }</p> <p>//<br /> // 主回调函数<br /> LRESULT CALLBACK MyWindowProc(<br /> HWND hwnd, // handle to window<br /> UINT uMsg, // message identifier<br /> WPARAM wParam, // first message parameter<br /> LPARAM lParam // second message parameter<br /> )<br /> {<br /> HDC hdc;<br /> PAINTSTRUCT ps;<br /> switch(uMsg)<br /> {<br /> case WM_PAINT:<br /> hdc = BeginPaint(hwnd, &ps);<br /> SelectObject(hdc, hfont);<br /> TextOut(hdc, 20, 70, TEXT("中华人民共和国"), lstrlen(TEXT("中华人民共和国")));<br /> EndPaint(hwnd, &ps);<br /> break;<br /> case WM_CREATE:<br /> hbSendSocket = CreateWindow(TEXT("button"), TEXT("测试"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON, 20, 20, 40, 20, hwnd, (HMENU)HB_SEND_SOCKET_ID, ((LPCREATESTRUCT)lParam) -> hInstance, NULL);<br /> SendMessage(hbSendSocket, WM_SETFONT,(WPARAM)hfont, TRUE);<br /> break;<br /> case WM_COMMAND:<br /> if(LOWORD(wParam) == HB_SEND_SOCKET_ID)<br /> {<br /> MessageBox(hwnd, TEXT("按钮被按下"), TEXT(TITLE_INFO), MB_OK);</p> <p> }<br /> break;<br /> case WM_CLOSE:<br /> if(IDYES == MessageBox(hwnd, TEXT("确定关闭?"), TEXT(TITLE_WARN), MB_YESNO))<br /> {<br /> DestroyWindow(hwnd);<br /> }<br /> break;<br /> case WM_DESTROY:<br /> PostQuitMessage(0);<br /> break;<br /> default:<br /> return DefWindowProc(hwnd, uMsg, wParam, lParam);<br /> }<br /> return 0;<br /> }</p> <p>//<br /> // 创建组件<br /> void CreateComponent(HWND hwnd, LPARAM lParam)<br /> {<br /> hbSendSocket = CreateWindow(TEXT("button"), NULL, WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON, 20, 20, 40, 20, hwnd, (HMENU)HB_SEND_SOCKET_ID, ((LPCREATESTRUCT)lParam) -> hInstance, NULL);<br /> }</p> <p>//<br /> // 初始化字体<br /> void InitSysFont(void)<br /> {<br /> LOGFONT font;<br /> memset(&font, 0, sizeof(font));<br /> font.lfHeight = 12;<br /> //font.lfWeight = FW_NORMAL;<br /> //font.lfCharSet = DEFAULT_CHARSET;//GB2312_CHARSET;<br /> //font.lfQuality = DEFAULT_QUALITY;<br /> lstrcpy(font.lfFaceName, TEXT("宋体"));<br /> hfont = CreateFontIndirect(&font);<br /> }

效果如下：
