It's in the HttpServerUtility class, but that is only available if you have an ASP.NET application.

You can use the HttpUtility.UrlEncode method instead.

I've added them as such

strNewValue = "login_form_username=" + HttpUtility.UrlEncode("user") + "&login_form_password=" + HttpUtility.UrlEncode("haslo") + "&from_module=" + HttpUtility.UrlEncode("home") + "&form_name=" + HttpUtility.UrlEncode("login");

and as such
... + "&from_module=home&form_name=login";

but with no result Frown | :(

Have you tried adding a value for the button, as I suggested earlier?

so right now the string value has grown to:

strNewValue = "login_form_username=" + HttpUtility.UrlEncode("user") + "&login_form_password=" + HttpUtility.UrlEncode("haslo") + "&loginBoxSubmit=" + HttpUtility.UrlEncode("Login") + "&from_module=" + HttpUtility.UrlEncode("home") + "&form_name=" + HttpUtility.UrlEncode("login");

but it didn't help

That looks right.

What message do you get when the login fails?

Does the login require cookies?

That means that the site did not even recognise the post. It thinks that it's just a regular request.

Re-check everything that you send in the post, so that you have spelled (or misspelled) everything correctly.

How declare event in C# class ? ? ? [modified]

Hi All,

I have simple C# class that hold some FORM.

This form hold some USER CONTROL`s.

What i need to do ( and i don't know how to do it ) is to send events from the some of the user control to this simple C# class and the C# class will also send events to those user control.

How do i declare those event in the C# class ? and how i send it from/to those user control ?

I don't want to make some function that will call the Form function and from the form to call the user control function ... i just want to do it directly from the class to/from the user control.

Thanks for any help.

You mean how to do cancel those events? i.e. if you have an event called BeforeClick you want to be able to say "no cancel that action" so that the main click event is not fired?

You mean: 'declare'? Re: How decline event in C# class ? ? ?

Sorry, but one can't understand what you want.
Maybe you can post the code that isn't working?

Failure is not an option - it's built right in.

Hello,

Yanshof wrote:
is to send events from the some of the user control to this simple C#

Your UserControl should implement an event like this:

public event EventHandler SomethingChanged;

and fire it like this:

if (SomethingChanged!= null) 
{
    SomethingChanged(this, EventArgs.Empty); //or implement your own EventArgs
}

Your class, (which holds the instance of the form where the usercontrols are on) should implement a method which returns a list of your UserControl:

private ArrayList GetAllUserControls(Control c, ArrayList allUserControls)
{
    if(allUserControls == null)
    {
	allUserControls = new ArrayList();
    }
    if(c!=null)
    {
	if(c.Controls!=null)
	{
            foreach(Control actControl in c.Controls)
            {
		YourUserControl actYourControl = actControl as YourUserControl;
		if(actYourControl!=null)
		{
                    allUserControls.Add(actYourControl);
		}
		//recursive call
		allUserControls= GetAllUserControls(actControl, allUserControls);
            }
	}
    }
    return allUserControls;
}

And call it like that:

ArrayList allUserControls = GetAllUserControls(yourForm, null);

Then you can register the Events.
I would recommend a method which does also the unregistering for your Dispose method.

private void EditEvent(ArrayList allUserControls, bool register)
{
    foreach(object o in allUserControls)
    {
	YourUserControl actYourControl = o as YourUserControl;
	if(actYourControl!=null)
	{
            if(register)
            {
		actYourControl.SomethingChanged+=new EventHandler(actYourControl_SomethingChanged);
            }
            else
            {
		actYourControl.SomethingChanged-=new EventHandler(actYourControl_SomethingChanged);
            }
        }
    }
}

And call it like that (you have to pass the List of UserControls which you got from the GetAllUserControls method):

EditEvent(allUserControls, true);

and in the dispose method:

EditEvent(allUserControls, false);

To find the correct instance in the handler:

private void actYourControl_SomethingChanged(object sender, EventArgs e)
{
    YourUserControl actYourControl = sender as YourUserControl;
    if(actYourControl!=null)
    {
 
    }
}

Here I would use a static event in the class.

Hope it helps!

The 'as' operator tries to cast the Control instance "actControl" to an instance of YourUserControl.
If the cast is not working it will return 'null', an ddoes not throw an exception (like "(YourUserControl)actControl" would do)

All the best,

Print the scrolled content of a windows form

I have a windows application in .net 2.0. I use a webbrowser control to display an asp page which is on server. Below the browser control i display an electronic signature.

My requirement is to print this form. I tried to use the memorygraphics class and take the screenshot of the form and draw the image to printer. But this gives me only the part of the form visible on the client area.
The part which is visible on scrolling the form is left. I need the complete form along with the scrolled part.

How do i do this? Can any one help me?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
