Sa fac sa comunice 2 formuri

Recommended Posts

Deci am facut un webbrowser in C#... nu e cine stie ce ...dar mam blocat undeva.....

 

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

Object reference not set to an instance of an object

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

 

 

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?
