Set Taskbar position Win7 c++

Question

Is it possible to set the taskbar position/width/height using the windows API? I'm running 3 monitors and I want to prevent the taskbar from spanning across all monitors and not stay on top all the time.

Here is what I have attempted so far with no luck... I'm not sure if there is something wrong with my code or it's just being blocked.

#include <iostream>
#include "Windows.h"

using namespace std;

class MyClass
{
public:
    int getTaskBarHeight();
    void setTaskBarPos();
};

int MyClass::getTaskBarHeight()
{
    RECT rect;
    HWND taskBar = FindWindow(L"Shell_traywnd", NULL);
    if(taskBar && GetWindowRect(taskBar, &rect)) {
        return rect.bottom - rect.top;
    }
}

void MyClass::setTaskBarPos()
{
    RECT rect;
    HWND taskBar = FindWindow(L"Shell_traywnd", NULL);
    if(taskBar && GetWindowRect(taskBar, &rect)) {

        SetWindowPos(taskBar, HWND_TOPMOST, 0, 0, 1080, 46, SWP_NOZORDER);

    }
}

int main(void)
{
    MyClass taskbar;
    cout << taskbar.getTaskBarHeight();

    taskbar.setTaskBarPos();

    int a;
    cin >> a;
}

Answer 1

To answer the "Spanning accross all 3 displays" question, this is normally down to the configuration of the display adapter. You can have 3 individual displays (1 per monitor), or 1 big display spanning accross all three monitors. The latter sounds like your situation, and Windows offers no way to make an app bar only take up part of a display.

Your best bet is to adjust the display driver to create 3 indiividual displays rather than 1 big one.
