Display hash in a text box?

[Silentexecute]

I'm very very new to C++ scripting as I'm developing an ASI script. I do have experience with LUA and C# for FiveM though but it doesn't seem to be helping .

I want to get the pickup hash for the entity I am aiming at and then display it in a text box (using an example from the natives database) but I cant seem to convert the hash to a string to display as I keep getting an error. I do know hashes are simply numbers but still doesn't help.

 

#include "script.h"

int main() {
	// cleanup code goes here

	while (true)
	{
		WAIT(0);
		Ped playerPed = PLAYER::PLAYER_PED_ID();
		Player player = PLAYER::PLAYER_ID();
		Entity target;
		bool AimingAt;
		Hash pickuphash;
		

		if (PLAYER::IS_PLAYER_FREE_AIMING(player)) {
			AimingAt = PLAYER::GET_ENTITY_PLAYER_IS_FREE_AIMING_AT(player, &target);
			if (AimingAt)
			{
				if (ENTITY::IS_ENTITY_AN_OBJECT(target) && OBJECT::_0x0378C08504160D0D(target)) { // IS_OBJECT_A_PICKUP
					pickuphash = OBJECT::_0x5EAAD83F8CFB4575(target); // GET_PICKUP_HASH
					string str = pickuphash::to_string();
					

					UI::_0xDD6CB2CCE7C2735C(1, "~INPUT_TALK~", str);

				}


			}


		}
		 // change this for delay time in loop
	}

	return 0;
}
void ScriptMain() {
	srand(GetTickCount64());
	throw main();
}
