I've been searching and searching around for a solution to this problem, but everything I read leads me to think that there isn't anything wrong with my code, but yet there is...

My MainForm opens up the AddTicketForm, to create and add an entry, prior to the closing of the AddTicketForm, it is supposed to call the function on the MainForm that will refresh the DataGrid, so that it will show the newly added entry... But for some reason it will not allow me on the AddTicketForm to create an object reference of the MainForm so that I may call the function... I keep getting the error "No overload for method 'MainForm' takes '0' arguments"... Here's my code...

namespace MPCS
{
	public partial class MainForm : Form
	{
		public void loadTicketsDataGrid(int CID)
		{
			ticketsDataGridView.DataSource = TicketsQueries.GetTicketsByCustomerID(CID);

			ticketsDataGridView.Columns[0].Name = "TicketID";
			ticketsDataGridView.Columns[0].DataPropertyName = "TicketID";
			ticketsDataGridView.Columns[0].Width = 5;
			ticketsDataGridView.Columns[0].HeaderText = "";
			ticketsDataGridView.Columns[0].Visible = false;

			etc. etc. etc.
		}
		private void addTicketToolStripMenuItem_Click(object sender, EventArgs e)
		{
			AddTicketForm AddTicketForm = new AddTicketForm(this);
			AddTicketForm.ShowDialog();
		}
	}
}

namespace MPCS
{
	public partial class AddTicketForm : Form
	{
		private int CID = 0;

		public AddTicketForm(MainForm Form1)
		{
			InitializeComponent();
			CID = Form1.CID;
		}
		private void newTicketButton_Click(object sender, EventArgs e)
		{
			code code code
			if (errorTracker == 0)
			{
				decimal ticketProfit = (ticketTotal * TherapistPercentage) / 100;
				TicketsQueries.InsertTicket(ticketDateTimePicker.Value, ticketDescriptionTextBox.Text, TID, CID, billedTime, billedRate, ticketTotal, ticketPaidComboBox.Text, ticketProfit);
				MainForm mForm = new MainForm();
				mForm.loadTicketsDataGrid(CID);
				this.Close();
			}
		}
	}
}

The error is on "MainForm mForm = new MainForm();"

You don't show the constructor for the MainForm class, but it appears that your MainForm constructor requires an argument you're not providing.

[webwired]

I don't understand, I can't imagine any arguments that the MainForm would require...

[wingot]

Hey webwired,

Your mainform is inheriting from Form but does not specify its own constructor. From my understanding it should just pick up Form's constructor, but the following code snippet in MainForm should make this work explicitly:

public void MainForm() : base()
{
}

the code that you posted for the "MainForm" class....is that ALL of the code in the class? or did you leave some out thinking it wasn't necessary?

I tried that, but as soon as I entered in that code, intellisense went nuts, underlining nearly everything in the form...

Err, sorry, remove the void and it should work .

Thank you wingot for your assistance, but it did the same thing...

Here's your problem

public MainForm(LogInForm LogInForm)
{
       InitializeComponent();
       TID = LogInForm.TID;
       therapistName = LogInForm.therapistName;
}

If you notice, in that signature it's expecting something of LogInForm and you seem to be passing it nothing. Also, the type and name of your parameter should never be the same

[Jayman]

If you explicitly define a constructor then you also have to explicitly define the default constructor for the class, as well.

The only time the default constructor exists is if you don't specify any constructors for your class.

So you are getting the error message because you do not have a default constructor that doesn't take any parameters.

From the LogInForm, I'm passing the TID and also the therapistName...

[PsychoCoder]

What is TID? You constructor is looking for the type LoginInForm which, from what I've read of your code, is the actual form.

Would you happen to have an example of how that works, sorry, this is quite a bit more different than VB .NET than I had expected, and learning C# has proven a bit more complex than I had originally anticipated...

PsychoCoder, on 21 Oct, 2008 - 09:49 AM, said:

In the LogInForm, a therapist enters a therapistName and a therapistPassword, it then queries the database and returns a TID, which is actually just short for therapistID... If a therapistID or TID is returned greater than zero, it opens up the MainForm for them... passing the TID and therapistName...

From what I researched and found, passing the Form was the easiest way of passing any of the variables within it...

Should I be using a different way?

your contructor should look like this...

public MainForm(LogInForm logInForm)
{
       InitializeComponent();
       TID = logInForm.TID;
       therapistName = logInForm.therapistName;
}

notice how "LogInForm" and "logInForm" are different? You can't give a variable name the same name as a class. "LogInName" is the data type and "logInName" is the variable.


EDITED: on second thought, instead of passing the entire form object, just pass what you need.

public MainForm(int tid, string name)
{
       InitializeComponent();
       TID = tid;
       therapistName = name;
}

and then your line of code that is currently give you the error should be this..

MainForm mForm = new MainForm(TID, therapistName);
