Experts,

I am looking to modify the following script:

#include <windows.h>
#include <stdio.h>

#pragma comment(lib, "user32.lib")

void DumpDevice(const DISPLAY_DEVICE& dd, size_t nSpaceCount )
{
    printf("%*sDevice Name: %s\n", nSpaceCount, "", dd.DeviceName );
    printf("%*sDevice String: %s\n", nSpaceCount, "", dd.DeviceString );
    printf("%*sState Flags: %x\n", nSpaceCount, "", dd.StateFlags );
    printf("%*sDeviceID: %s\n", nSpaceCount, "", dd.DeviceID );
    printf("%*sDeviceKey: ...%s\n\n", nSpaceCount, "", dd.DeviceKey+42 );
}

int main()
{
    DISPLAY_DEVICE dd;

    dd.cb = sizeof(DISPLAY_DEVICE);

    DWORD deviceNum = 0;
    while( EnumDisplayDevices(NULL, deviceNum, &dd, 0) ){
        DumpDevice( dd, 0 );
        DISPLAY_DEVICE newdd = {0};
        newdd.cb = sizeof(DISPLAY_DEVICE);
        DWORD monitorNum = 0;
        while ( EnumDisplayDevices(dd.DeviceName, monitorNum, &newdd, 0))
        {
            DumpDevice( newdd, 4 );
            monitorNum++;
        }
        puts("");
        deviceNum++;
    }

    return 0;
}

Open in new window


The output of this code should display only the monitor information:

IE
\\.\DISPLAY1\Monitor0
\\.\DISPLAY1\Monitor1
\\.\DISPLAY1\Monitor2

I also need to know if the device is PnP or UPnp

Device Name: \\.\DISPLAY1\Monitor0
   Device String: Generic PnP Monitor
   State Flags: 3
   DeviceID: MONITOR\DEL4016\{4d36e96e-e325-11ce-bfc1-08002be10318}\0002
   DeviceKey: ...\Control\Class\{4d36e96e-e325-11ce-bfc1-08002be10318}\0002

Thanks in advance for you assistance with this.

That would be quite straightfoward, e.g.

#include <windows.h>
#include <stdio.h>

#pragma comment(lib, "user32.lib")

void DumpDevice(const DISPLAY_DEVICE& dd, size_t nSpaceCount )
{
    char* pPnP = NULL;

    if (strstr(dd.DeviceString, "PnP")) pPnP = "PnP";

    if (strstr(dd.DeviceString, "UPnP")) pPnP = "UPnP";
    
    printf("%*sDevice Name: %s, Mode: %s\n", nSpaceCount, "", dd.DeviceName, pPnP ? pPnP : "None detected" );
}

int main()
{
    DISPLAY_DEVICE dd;

    dd.cb = sizeof(DISPLAY_DEVICE);

    DWORD deviceNum = 0;
    while( EnumDisplayDevices(NULL, deviceNum, &dd, 0) ){

        DISPLAY_DEVICE newdd = {0};
        newdd.cb = sizeof(DISPLAY_DEVICE);
        DWORD monitorNum = 0;
        while ( EnumDisplayDevices(dd.DeviceName, monitorNum, &newdd, 0))
        {
            DumpDevice( newdd, 0 );
            monitorNum++;
        }
        puts("");
        deviceNum++;
    }

    return 0;
}
                                  

Open in new window


However, "PnP" can only be detected when that info is included in the device string...
