螢幕亮度設定程式 BrightControl

    看影片時候要把螢幕調到最亮，可是瀏覽網頁這種亮度又太刺眼，如果你經常要配合不同的應用調整螢幕亮度，而你的螢幕又不是EIZO的話，那這個程式可以幫你做到單鍵調整螢幕亮度，省去按螢幕OSD調整亮度的麻煩。

如果你要自己寫一個的話，以下是參考資料及程式片段，我是用VS2008兜出來的。 

SetMonitorBrightness Dxva2.lib // Minimum supported client Windows Vista 

它應該是用 DDC 來控制螢幕的，不過這些 API 只有在 Vista 以上提供，我自己是在Windows7上使用。 

#include<HighLevelMonitorConfigurationAPI.h>

int CMonConfDlg::SetMonitorBright(HWND hWnd , DWORD cBrightness)

{

HMONITOR hMonitor = NULL;

DWORD cPhysicalMonitors;

DWORD minb=0;

DWORD curb=0;

DWORD maxb=0;

LPPHYSICAL_MONITOR pPhysicalMonitors = NULL;

// Get the monitor handle.

hMonitor = MonitorFromWindow(hWnd, MONITOR_DEFAULTTOPRIMARY);

// Get the number of physical monitors.

BOOL bSuccess = GetNumberOfPhysicalMonitorsFromHMONITOR(

hMonitor, &cPhysicalMonitors);

if (bSuccess)

{

// Allocate the array of PHYSICAL_MONITOR structures.

pPhysicalMonitors = (LPPHYSICAL_MONITOR)malloc(

cPhysicalMonitors* sizeof(PHYSICAL_MONITOR));

if (pPhysicalMonitors != NULL)

{

// Get the array.

bSuccess = GetPhysicalMonitorsFromHMONITOR(hMonitor, cPhysicalMonitors, pPhysicalMonitors);

int n = 0;

do {

bSuccess = GetMonitorBrightness(pPhysicalMonitors->hPhysicalMonitor , &minb, &curb, &maxb);

if( !bSuccess ) {

dbg_printf("GetMonitorBrightness, n = %d, bSuccess = %d\r\r\n", n, bSuccess);

        GetErrorMessage(TEXT("GetMonitorBrightness"));

Sleep(RETRY_SLEEP);

}

n++;

} while( !bSuccess && n < MAX_RETRY);

if( bSuccess ) {

if( curb != cBrightness && minb <= cBrightness && cBrightness <= maxb ) {

int n = 0;

do {

bSuccess = SetMonitorBrightness(pPhysicalMonitors->hPhysicalMonitor , cBrightness);

if( !bSuccess ) {

dbg_printf("SetMonitorBrightness, n = %d, bSuccess = %d\r\r\n", n, bSuccess);

        GetErrorMessage(TEXT("SetMonitorBrightness"));

Sleep(RETRY_SLEEP);

}

n++;

} while( !bSuccess && n < MAX_RETRY);

dbg_printf("SetMonitorBrightness(%d), bSuccess = %d\r\r\n",cBrightness, bSuccess);

}

}

// Close the monitor handles.

        bSuccess = DestroyPhysicalMonitors( cPhysicalMonitors, pPhysicalMonitors);

// Free the array.

free(pPhysicalMonitors);

}

}

return curb;

}
