Disable win7 glass Effect

Disable win7 glass Effect

From: blog.csdn.net/windows_nt

Dwmenablecomposition: Call this function to disable the glass effect of the entire system.

Dwmsetwindowattribute calls this function to close the glass effect of a window.

Only applicable to XP and later systems, because the XP system does not have the Link Library dwmapi. dll.

 

Run the following code in the bool cxxapp: initinstance () of the program to call

 

Disable system glass Effect

Typedef hresult (_ stdcall * lpfndwmiscompositionenabled) (bool * State );

Typedef hresult (_ stdcall * lpfndwmenablecomposition) (uint setstate );
Lpfndwmiscompositionenabled lpfnisenabled = 0;
Lpfndwmenablecomposition lpfnsetenable = 0;
 
Hmodule library =: loadlibrary (_ T ("dwmapi. dll "));
Bool result = 0;
 
If (0! = Library)
{
Lpfnisenabled = (lpfndwmiscompositionenabled) getprocaddress (library, "dwmiscompositionenabled ");
Lpfnsetenable = (lpfndwmenablecomposition) getprocaddress (library, "dwmenablecomposition ");

If (lpfnisenabled! = 0)
{
Bool enabled = false;
Result = succeeded (lpfnisenabled (& enabled) & enabled;
}

If (Result & lpfnsetenable! = 0)
{
Result = succeeded (lpfnsetenable (0/* disable */));
}

Verify (: freelibrary (Library ));

Close the glass effect of a window
If the compiler is a version later than vs2008, the code is very simple. You only need to add the following code in the window initialization:

Dwmncrenderingpolicy NCRP = dwmncrp_disabled;
Dwmsetwindowattribute (getsafehwnd (), dwmwa_ncrendering_policy, & NCRP, sizeof (NCRP ));

Include # include <dwmapi. h>

If the compiling environment is lower than vs2008 and there is no Vista SDK, the following code is used:

Since there is no dwmapi. h file in the compiling environment, you must add the following definitions.

// Close the glass effect of an application. This code must be placed after the m_pmainwnd pointer is assigned a value and the following code is called:
Enum dwm?wattri=
{
Dwmwa_ncrendering_enabled = 1, // [get] is non-client rendering enabled/disabled
Dwmwa_ncrendering_policy, // [set] non-client rendering Policy
Dwmwa_transitions_forcedisabled, // [set] potentially enable/forcibly disable transitions
Dwmwa_allow_ncpaint, // [set] Allow contents rendered in the non-client area to be visible on the DWM-drawn frame.
Dwmwa_caption_button_bounds, // [get] bounds of the caption button area in window-relative space.
Dwmwa_nonclient_rtl_layout, // [set] is non-client content RTL mirrored
Dwmwa_force_iconic_representation, // [set] force this window to display iconic thumbnails.
Dwmwa_flip3d_policy, // [set] designates how flip3d will treat the window.
Dwmwa_extended_frame_bounds, // [get] gets the extended frame bounds rectangle in screen space
Dwmwa_last
};
Typedef Enum _ dwmncrenderingpolicy {
Dwmncrp_usewindowstyle,
Dwmncrp_disabled,
Dwmncrp_enabled,
Dwmncrp_last
} Dwmncrenderingpolicy;

Then we can get the function of removing the glass effect (dwmset?wattri=) in the dynamic link library and then execute this function.
Typedef hresult (winapi * tmpfun) (hwnd, DWORD, lpcvoid, DWORD );
Hmodule library =: loadlibrary ("dwmapi. dll ");

Tmpfun dwmset?wattributeex;
If (0! = Library)
{
Dwmsetaskwattributeex = (tmpfun): getprocaddress (library,
"Dwmsetaskwattribute ");
If (dwmsetwindowattributeex)
{
Dwmncrenderingpolicy NCRP = dwmncrp_disabled;
(* Dwmsetwindowattributeex) (m_pmainwnd-> getsafehwnd (), dwmwa_ncrendering_policy, & NCRP, sizeof (NCRP ));

}
Verify (: freelibrary (Library ));
}
