Win32-SDK常用API函数总结（一）.doc

1、几年没用 vc 写代码了。偶尔发现之前整理的一些知识点，删除吧又觉得可惜，就拿出来与大家分享下！若发现有神马错误的地方，请留言，不胜感激！邮箱: Win32 SDK 常用 API 函数总结（一）1、 创建模态对话框：int DialogBox( HINSTANCE hInstance, LPCTSTR lpTemplate, HWND hWndParent, DLGPROC lpDialogFunc );（注：IDD_MAIN 为资源 ID，MainDlgProc 为回调函数，详细参数参考 MSDN）2、 对话框常用消息：（不全面，仅供参考）1） 对话框显示时，会触发一个 WM_INITDIA

2、LOG 消息。LRESULT CALLBACK WindowProc(HWND hwnd, / handle to windowUINT uMsg, / WM_INITDIALOGWPARAM wParam, / handle to control (HWND)LPARAM lParam / initialization parameter);2） 对话框上的滚动条或滑动条控件等被操作时，触发一个 WM_HSCROLL 消息。LRESULT CALLBACK WindowProc(HWND hwnd, / handle to windowUINT uMsg, / WM_HSCROLLWPARA

3、M wParam, / request and positionLPARAM lParam / handle to scroll bar (HWND);3） 对话框上的按钮、组合框、列表框等被操作时，触发出一个 WM_COMMAND 消息。LRESULT CALLBACK WindowProc(HWND hwnd, / handle to windowUINT uMsg, / WM_COMMANDWPARAM wParam, / notification code and identifierLPARAM lParam / handle to control (HWND); wParam Th

4、e high-order word specifies the notification code if the message is from a ontrol. If the message is from an accelerator, this value is 1. If the message is from a menu, this value is zero. The low-order word specifies the identifier of the menu item, control, or accelerator. lParam Handle to the co

5、ntrol sending the message if the message is from a control. Otherwise, this parameter is NULL. 4） 点击最大化或最小化，会触发一个 WM_SIZE 消息。LRESULT CALLBACK WindowProc(HWND hwnd, / handle to windowUINT uMsg, / WM_SIZEWPARAM wParam, / resizing flagLPARAM lParam / client area);wParam Specifies the type of resizing r

6、equested. This parameter can be one of the following values. Value MeaningSIZE_MAXHIDE Message is sent to all pop-up windows when some other window is maximized.SIZE_MAXIMIZED The window has been maximized.SIZE_MAXSHOW Message is sent to all pop-up windows when some other window has been restored to

7、 its former size.SIZE_MINIMIZED The window has been minimized.SIZE_RESTORED The window has been resized, but neither the SIZE_MINIMIZED nor SIZE_MAXIMIZED value applies.lParam The low-order word of lParam specifies the new width of the client area. The high-order word of lParam specifies the new hei

8、ght of the client area. 5） 点击关闭，触发一个 WM_CLOSE:消息LRESULT CALLBACK WindowProc(HWND hwnd, / handle to windowUINT uMsg, / WM_CLOSEWPARAM wParam, / not usedLPARAM lParam / not used);ParametersThis message has no parameters. 3、 常用的 API：（不全面，仅供参考）（1）对话框1） 创建对话框：INT_PTR DialogBox(HINSTANCE hInstance, / hand

9、le to moduleLPCTSTR lpTemplate, / dialog box templateHWND hWndParent, / handle to owner windowDLGPROC lpDialogFunc / dialog box procedure);2） 关闭对话框：BOOL EndDialog(HWND hDlg, / handle to dialog boxINT_PTR nResult / value to return);3） 获取对话框上控件的句柄：HWND GetDlgItem(HWND hDlg, / handle to dialog boxint n

10、IDDlgItem / control identifier);4） 修改对话框的图标：SendMessage( (HWND) hWnd, / handle to destination window WM_SETICON, / message to send(WPARAM) wParam, / icon type(LPARAM) lParam / handle to icon (HICON);（2）组合框1） 为组合框控件增加项：SendMessage( (HWND) hWnd, / handle to destination window CB_ADDSTRING, / message t

11、o send(WPARAM) wParam, / not used; must be zero(LPARAM) lParam / string to add (LPCTSTR); 2） 设置组合框的当前选项：SendMessage( (HWND) hWnd, / handle to destination window CB_SETCURSEL, / message to send(WPARAM) wParam, / item index(LPARAM) lParam / not used; must be zero);（注：建议组合框控件属性去掉 sort ，依次添加组合框的项，那么索引号就

12、为0，1，2，3.，这样便于控制）3） 获得当前选中项的索引值：（返回值即为索引值）SendMessage( (HWND) hWnd, / handle to destination window CB_GETCURSEL, / message to send0, 0 );（3）静态文本1） 设置静态文本：BOOL SetWindowText(HWND hWnd, / handle to window or controlLPCTSTR lpString / title or text);2）获取静态文本：int GetWindowText(HWND hWnd, / handle to win

13、dow or controlLPTSTR lpString, / text bufferint nMaxCount / maximum number of characters to copy);4、 滑动条1）设置范围：SendMessage( (HWND) hWnd, / handle to destination window TBM_SETRANGE, / message to send(WPARAM) TRUE, (LPARAM) MAKELONG(lMinimum, lMaximum) );2） 设置当前值：SendMessage(HWND) hWnd, TBM_SETPOS,(W

14、PARAM) TRUE, (LPARAM) Value); 3） 获得当前值：（返回值为一个 32位数，就是当前位置的值）SendMessage(HWND) hWnd, TBM_GETPOS,0, 0); 5、 窗口1） 使窗口无效（有效）：BOOL EnableWindow(HWND hWnd, / handle to windowBOOL bEnable / enable or disable input);6、 常用对话框注：对于保存文件对话框、打开文件对话框、颜色对话框等网上资料较多，不做介绍。1） 文件路径对话框BOOL SHGetPathFromIDList(LPCITEMIDLIST pidl,LPSTR pszPath);注：其他类似的函数，可以参照 MSDN以 SH开头的函数2013.2.21 于雁联
