If you cannot do that in CSS:) take an image of boxes, and when click to change an image. But thats not what you want. Be smart:)

Yes, it's using.

This is my makefile (cmake):
add_subdirectory(keypad)

if (NOT PICO_NO_HARDWARE)
add_subdirectory(lcd_i2c_quotes)
endif ()

add_executable(blink
doorlock.cpp
#lcd_i2c_quotes/lcd_i2c_test.cpp
lcd_i2c_quotes/lcd_i2c.cpp
keypad/pico_keypad4x4.c
keypad/pico_keypad4x4.h
)

# Pull in our pico_stdlib which pulls in commonly used features
target_link_libraries(blink PUBLIC pico_stdlib hardware_gpio hardware_adc hardware_pwm hardware_i2c hardware_timer)

# create map/bin/hex file etc.
pico_add_extra_outputs(blink)

# add url via pico_set_program_url
example_auto_set_url(blink)

I'am linked a library as executable? Ok, but to change how?

Hi, Maciej Los, program showed a error. I'am created program from Microsoft Docs.
This is code of all program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Security;
using System.Security.Policy;
using System.Security.Permissions;
using System.Reflection;
using System.Runtime.Remoting;
using System.Windows.Forms;

namespace UkiSanbox
{
static class Program
{
///

/// The main entry point for the application.
///

class Sandboxer : MarshalByRefObject
{

const string pathToUntrusted = @"..\..\..\UkiSanbox\bin\Debug";
const string untrustedAssembly = "UntrustedCode";
const string untrustedClass = "UntrustedCode.UntrustedClass";
const string entryPoint = "IsFibonacci";
private static Object[] parameters = { 45 };
static void Main()
{
AppDomainSetup adSetup = new AppDomainSetup();
adSetup.ApplicationBase = Path.GetFullPath(pathToUntrusted);


PermissionSet permSet = new PermissionSet(PermissionState.None);
permSet.AddPermission(new SecurityPermission(SecurityPermissionFlag.Execution));


StrongName fullTrustAssembly = typeof(Sandboxer).Assembly.Evidence.GetHostEvidence<strongname>();


AppDomain newDomain = AppDomain.CreateDomain("Sandbox", null, adSetup, permSet, fullTrustAssembly);


ObjectHandle handle = Activator.CreateInstanceFrom(
newDomain, typeof(Sandboxer).Assembly.ManifestModule.FullyQualifiedName,
typeof(Sandboxer).FullName
);

Sandboxer newDomainInstance = (Sandboxer)handle.Unwrap();
newDomainInstance.ExecuteUntrustedCode(untrustedAssembly, untrustedClass, entryPoint, parameters);
}

public void ExecuteUntrustedCode(string assemblyName, string typeName, string entryPoint, Object[] parameters)
{

MethodInfo target = Assembly.Load(assemblyName).GetType(typeName).GetMethod(entryPoint);
try
{

bool retVal = (bool)target.Invoke(null, parameters);
}
catch (Exception ex)
{

new PermissionSet(PermissionState.Unrestricted).Assert();
Console.WriteLine("SecurityException caught:\n{0}", ex.ToString());
CodeAccessPermission.RevertAssert();
Console.ReadLine();
}
}
}
}
}

And program show problem in this line code:

AppDomain newDomain = AppDomain.CreateDomain("Sandbox", null, adSetup, permSet, fullTrustAssembly);

Problem is this: System.ArgumentException: 'A null StrongName was found in the full trust assembly list.'

How to fix it?
