Get the value of textbox100, but the textbox100 is in Form2.

Joao Rafael

I want to hide a button when the DateTime.Now = a input date by user. The textbox100 is in the Form2 and is already public, but i know something is missing. Need some help please. Thank you.

public void Form1_Load(object sender, EventArgs e)
{
        var dateTimeStr = textbox100.Text;
        var user_time = DateTime.Parse(dateTimeStr);
        var time_now = DateTime.Now;

        if (time_now >= user_time)
        {
        button1.Visible = false;
        }
}

I've already found a solution, but thanks anyway. I want to open it when Form1 is loading, because i want to hide the button immediately, it´s like a demo software, the application will be useless without that button. Thank you.

I did it like this:

public Form2 frm2 = new Form2();

public void Form1_Load(object sender, EventArgs e)
{
        var dateTimeStr = frm2.textBox100.Text;
        var user_time = DateTime.Parse(dateTimeStr);
        var time_now = DateTime.Now;

        if (time_now >= user_time)
        {
        button1.Visible = false;
        }
}

Well, I would normally have answered:

public void Form1_Load(object sender, EventArgs e)
{
Form2 f2 = Application.OpenForms["Form2"] as Form2;
if (f2 != null)
{
var dateTimeStr = f2.textbox100.Text;
var user_time = DateTime.Parse(dateTimeStr);
var time_now = DateTime.Now;

if (time_now >= user_time)
{
button1.Visible = false;
}
}
}

but I'm puzzled as to how Form2 can already be open when you're just loading Form1?
