Detect Main Display

[telco]

Hello everyone.. i only learn from reading here and from samples given from users.

Now i have found a sample to Detect 2 display using PablokoMonitor

my question now is i have 2 monitors AOC in 1920x1080 and Acer in 1600x900
how can the apps detect which the Main Display?

Never heard of it post the apz I am sure there will be a way to edit find monitor one if it finds monitor 2

[Imagine Programming]

local user32 = Library.Load("user32.dll");

MONITOR_DEFAULTTONULL    = 0;
MONITOR_DEFAULTTOPRIMARY = 1;
MONITOR_DEFAULTTONEAREST = 2;

RECT = MemoryEx.DefineStruct{
    DWORD         "left";
    DWORD        "top";
    DWORD        "right";
    DWORD        "bottom";
};

MONITORINFO = MemoryEx.DefineStruct{
    DWORD         "cbSize";
    RECT         "rcMonitor";
    RECT        "rcWork";
    DWORD        "dwFlags";    
};

function MonitorFromWindow(hWnd, dwFlags)
    return user32.MonitorFromWindow(hWnd, dwFlags);
end

function GetMonitorInfo(hMonitor)
    local info = MONITORINFO:New();
    if(not info)then
        error("memory allocation failure", 2);
    end 
    
    info.cbSize = info:Size();
    local result = user32.GetMonitorInfoA(hMonitor, info:GetPointer());
    if(result == 0)then
        info:Free();
        return nil;
    end
    
    return info;
end

function IsOnPrimaryMonitor(hWnd)
    local hMonitor = MonitorFromWindow(hWnd, MONITOR_DEFAULTTONULL);
    if(hMonitor == 0)then 
        return false;
    end 
    
    local info = GetMonitorInfo(hMonitor);
    if(info)then
        local result = info.rcMonitor.left == 0 and info.rcMonitor.top == 0;
    
        info:Free();
        
        return result;
    end 
    
    return false;
end;

Put that in Globals, call as IsOnPrimaryMonitor(Application.GetWndHandle()) from a button or On Show. Tell me if it works

It uses the MemoryEx plugin (https://www.memoryex.net/mx.html)

Post the next code in Globals:

local user32 = Library.Load("user32.dll");

MONITOR_DEFAULTTONULL    = 0;
MONITOR_DEFAULTTOPRIMARY = 1;
MONITOR_DEFAULTTONEAREST = 2;

RECT = MemoryEx.DefineStruct{
    DWORD         "left";
    DWORD        "top";
    DWORD        "right";
    DWORD        "bottom";
};

MONITORINFO = MemoryEx.DefineStruct{
    DWORD         "cbSize";
    RECT         "rcMonitor";
    RECT        "rcWork";
    DWORD        "dwFlags";    
};

function MonitorFromWindow(hWnd, dwFlags)
    return user32.MonitorFromWindow(hWnd, dwFlags);
end

function GetMonitorInfo(hMonitor)
    local info = MONITORINFO:New();
    if(not info)then
        error("memory allocation failure", 2);
    end 
    
    info.cbSize = info:Size();
    local result = user32.GetMonitorInfoA(hMonitor, info:GetPointer());
    if(result == 0)then
        info:Free();
        return nil;
    end
    
    return info;
end

function IsOnPrimaryMonitor(hWnd)
    local hMonitor = MonitorFromWindow(hWnd, MONITOR_DEFAULTTONULL);
    if(hMonitor == 0)then 
        return false;
    end 
    
    local info = GetMonitorInfo(hMonitor);
    if(info)then
        local result = info.rcMonitor.left == 0 and info.rcMonitor.top == 0;
    
        info:Free();
        
        return result;
    end 
    
    return false;
end;

Use in On Show or in a button, not in On Preload;

local mainMonitor = IsOnPrimaryMonitor(Application.GetWndHandle());

It requires the MemoryEx Action Plugin to do the advanced stuff.

I want to help you, but the IR forums tell me my reply is unapproved each time I post something....

[Imagine Programming]

Let's try it like this (see the Globals Section for the reply I was going to post)

[telco]

Thanks Imagine but i can find how to fix the error..

[telco]

thanks imagine i restart the app.. and it works... thanks so much

I'm glad that it works.

Hello imagine,, maybe there is wrong with my post.. detecting which is the main display is great but i realize this is not what i need to achieve...
what really in my mind is detecting which is the monitor 1 and which is the Monitor 2..

The the settings of windows on display there is a button identify and it shows on screen the number of each monitor.. can you help me on this?

example: Get the Monitor # and get the current resolutoion of the monitor..

Monitor 1, 1920x1080, location is Left , -1920, Top-0,
Monitor 2, 1366x768, location is, Right 1600, Top 0

[Imagine Programming]

Check this example, which lists all available monitors. It also shows you how you can determine the primary monitor in the list with code.

Read more about the rcMonitor and rcWork fields of the MONITORINFO structure here: https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

Edit: Fixed a bug in the example code and added more verbose comments

Thanks for this imagine.. i will look unto it and study all the codes.. Thank you and God Bless

It's best that you start another thread for a question with a different subject. I also don't have that plugin, so I don't know what is happening.
