Changing the title of uwp process - c++

Question

I want to change the title bar of calc.exe. I read that it's done via SetWindowTextA() but when I used this it only change the title of the preview (1) and I want to change title at (2) as well.
Can anyone explain for me why it change the title at (1) not (2) and how can I change the title at (2)

Answer 1

The Calculator title is Text Control Type retrieved using UI Automation. However according to Text Control Type, the IValueProvider is never supported by text controls. So you can’t.
Edit:
#include <Windows.h>
#include <UIAutomation.h>
#include <wchar.h>
int Element(IUIAutomation* automation)
{
// Get the element under the cursor
// Use GetPhysicalCursorPos to interact properly with
// High DPI
POINT pt;
GetPhysicalCursorPos(&pt);
IUIAutomationElement* pAtMouse;
HRESULT hr = automation->ElementFromPoint(pt, &pAtMouse);
if (FAILED(hr))
return hr;
// Get the element's name and print it
BSTR name;
hr = pAtMouse->get_CurrentName(&name);
if (SUCCEEDED(hr))
{
IUIAutomationTextPattern* pattern;
pAtMouse->GetCurrentPatternAs(UIA_TextPatternId, IID_IUIAutomationTextPattern,(void**)&pattern);
//TODO
wprintf(L"Element's Name: %s \n", name);
SysFreeString(name);
}
// Get the element's Control Type (in the current languange)
// and print it
BSTR controlType;
hr = pAtMouse->get_CurrentLocalizedControlType(&controlType);
if (SUCCEEDED(hr))
{
wprintf(L"Element's Control Type: %s \n", controlType);
SysFreeString(controlType);
}
// Clean up our COM pointers
pAtMouse->Release();
return hr;
}
int main(int argc, TCHAR* argv[])
{
// Initialize COM and create the main Automation object
IUIAutomation* g_pAutomation;
CoInitialize(NULL);
HRESULT hr = CoCreateInstance(__uuidof(CUIAutomation), NULL,
CLSCTX_INPROC_SERVER, __uuidof(IUIAutomation),
(void**)&g_pAutomation);
if (FAILED(hr))
return (hr);
bool quit = false;
while (!quit)
{
SHORT leftControlMod = GetAsyncKeyState(VK_LCONTROL);
if (leftControlMod != 0)
{
Element(g_pAutomation);
}
quit = GetAsyncKeyState(VK_ESCAPE);
}
g_pAutomation->Release();
CoUninitialize();
return 0;
}
