im working in .cs so i think this is the right section the body of the pages look like this <body>Online</body> <body>0/8</body> it shows only the data i want to get i tried this private void Form1_Load(object sender, EventArgs e) { String queryString = "http://blackbullstudio.ddns.net:81/Websiteassets/GTA/players.php?"; }

you need to get the label you want to change and set its Text property e.g.

private void Form1_Load(blah...)
{
  myLabel.Text = "hello world";
}

private void Form1_Load(blah...)
{
  myLabel.Text = "hello world";
}

yeah i get that but the url i get needs to return the data i need

becquerel•3y ago

if you right-click on the label and go to 'properties', i think it shows you the name there. been a while since i did winforms oh, you actually wanna call the page

you need async in your method definition private async void

BlackBullOP•3y ago

aah okey

becquerel•3y ago

async lets you use await, await lets you make HTTP calls without freezing your app, basically
