设置窗体透明 隐藏任务栏 与全屏显示

因为一种特别的需要 做了一个小程序主要三个功能

设置窗体透明

void CSetDlg::SetTransparent() { ::SetWindowPos(m_hWnd,HWND_TOPMOST,0,0,0,0,SWP_NOSIZE|SWP_NOMOVE);//TopMost SetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE,GetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE)^0x80000); HINSTANCE hModule=LoadLibrary("User32.DLL"); if(hModule==NULL) { return; } typedef BOOL (WINAPI *FN_SetColor)(HWND,COLORREF,BYTE,DWORD); FN_SetColor SetColor = NULL; SetColor=(FN_SetColor)GetProcAddress(hModule,"SetLayeredWindowAttributes"); if (SetColor==NULL) { return; FreeLibrary(hModule); } SetColor(this->GetSafeHwnd(),0,50,2); FreeLibrary(hModule); }

全屏幕显示窗体

void CSetDlg::SetFullScreen() { LONG style = ::GetWindowLong(this->m_hWnd,GWL_STYLE); style &= ~(WS_DLGFRAME | WS_THICKFRAME); SetWindowLong(this->m_hWnd,GWL_STYLE, style); this->ShowWindow(SW_SHOWMAXIMIZED); CRect rect; this->GetWindowRect(&rect); ::SetWindowPos(this->m_hWnd,HWND_NOTOPMOST,rect.left-1, rect.top-1, rect.right-rect.left + 3, rect.bottom-rect.top + 3, SWP_FRAMECHANGED); }

隐藏任务栏

void CSetDlg::SetTaskBarHide() { ::SetWindowLong(GetSafeHwnd(),GWL_EXSTYLE, WS_EX_TOOLWINDOW); }
