Am facut un dialog in care sa setezi homepage, dar am o mica problema, in acest dialog am un buton numit get current care teoretic ar trebui sa imi ia pagina actuala din
webbrowser si sa o puna intrun textbox numit textBox1
Si am facut ceva de genu
1. Am facut controlul de la web browserul public..
2. Am facut text boxul din dialogul unde setez homeul public.
3. Am facut buttonul Get Current Public
4. Asta e codul de la butonul pe care trebuie sa apesi ca sa itzi apara dialogul unde setezi home
private void setHomeToolStripMenuItem_Click_1(object sender, EventArgs e)
{
string getcurrent = webBrowser1.Document.Url.ToString();
home hmPg = new home();
hmPg.Show();
}5. Asta e codul de la butonul care ar trebui sa ia pagina actuala si sa o puna in textbox
private void button3_Click(object sender, EventArgs e)
{
Form1 frm = new Form1();
WebBrowser wbs = frm.webBrowser1;
textBox1.Text = wbs.Url.ToString();
}In cazul de mai sus am o eroare de genu

In caz ca schimb codul din punctul 5 cu acesta
private void button3_Click(object sender, EventArgs e)
{
Form1 frm = new Form1();
WebBrowser wbs = frm.webBrowser1;
textBox1.Text = wbs.Document.Url.ToString();
}Imi ia homepageul deja stabilit si il pune in Textbox
Idei?
