2.1 获得控件的窗口句柄。
slider control也是一个窗口是对话框的子窗口因此要用GetDlgItem来实现
backlight_wnd GetDlgItem(hDlg, IDC_SLIDER_BACKLIGHT); //注意下面示例中蓝色标出的区别
2.2 设置slider control的区间是给slider control发TBM_SETRANGE消息比如我设置0到100就是
SendMessage(backlight_wnd,TBM_SETRANGE, (WPARAM)1,(LPARAM)MAKELONG(0,100));
2.3 设置滑块的初始位置是发送TBM_SETPOS消息来实现的 SendMessage(backlight_wnd,TBM_SETPOS, (WPARAM)1,(LPARAM)BacklightPercentage); 2.4 slider control和用户的交互则是通过WM_HSCROLL消息来实现的需要在WM_HSCROLL的响应函数里面发送TBM_GETPOS消息得到当前滑块的位置
BacklightPercentage (unsigned char)SendMessage(backlight_wnd,TBM_GETPOS,0,0);
2.5 旁边的一个当前刻度的数字的说明需要先设定一个Static text文本控件然后动态给该控件发送WM_SETTEXT消息来实现动态的更新数字
SendMessage(GetDlgItem(hDlg, IDC_STATIC_BACKLIGHT_VALUE), WM_SETTEXT, 0, LPARAM(szBacklightPercentage));
最后面的那个参数szBacklightPercentage是一个字符串。 INT_PTR WINAPI DlgProcTouMingSet(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) {PAINTSTRUCT ps;HDC hdcAbout;int EscKeyID1000;int ReturnID1001;HWND backlight_wnd;switch (uMsg){case WM_INITDIALOG:{RegisterHotKey(hwnd,EscKeyID,0,VK_ESCAPE);RegisterHotKey(hwnd,ReturnID,0,VK_RETURN);backlight_wnd GetDlgItem(hwnd,IDC_SLIDER_TouMing);//2.2 设置slider control的区间是给slider control发TBM_SETRANGE消息比如我设置0到100就是SendMessage(backlight_wnd,TBM_SETRANGE, (WPARAM)1,(LPARAM)MAKELONG(15,255));int TouMingChuShi GetPrivateProfileInt(_T(SkinChoose),_T(TouMing),150,defaultFullFullPath);SendMessage(backlight_wnd,TBM_SETPOS, (WPARAM)1,TouMingChuShi); //读取初始透明度}break;case WM_HSCROLL:{int nScrollCode (int) LOWORD(wParam); // scroll bar value //int nPos (int) HIWORD(wParam); // scroll box position HWND hwndScrollBar (HWND) lParam; // handle to scroll bar lParam一般表示窗口句柄
