Set the transparent hidden taskbar and full screen display of the form

Because of a special need Made a small program with three main functions

Set form transparency

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);

}

Full screen display form

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);

}

Hide taskbar

void CSetDlg::SetTaskBarHide()

{

::SetWindowLong(GetSafeHwnd(),GWL_EXSTYLE, WS_EX_TOOLWINDOW);

}
