Hi everybody!

I have two forms in C#. In the main form I have procedure that i need to
run from second form when I click button. How I do it?

Thanks for help, gregory.
 
Create an 'internal' or 'public' procedure in Form2...

\\\
internal void myProcedure()
{
MessageBox.Show("Procedure in Form2", "MyProject");
}
///

....then call it from Form1...

\\\
private void button1_Click(object sender, System.EventArgs e)
{
Form2 objForm2 = new Form2();

objForm2.Show();
objForm2.myProcedure();
}
///

HTH,
Gary

If you answer the following question, it'll be easier to give you a
decent answer: What does this procedure do?
 
Gregory,

In that case, in Form1 create an 'internal' or 'public' procedure...

\\\
internal void myProcedure()
{
MessageBox.Show("Procedure in Form1", "MyProject");
}
///

....then in Form2 create an overloaded constructor that will take a reference
to Form1...

\\\
private Form1 myForm1;

public Form2(Form1 objForm1)
{
myForm1 = objForm1;

InitializeComponent();
}
///

....and when you create and instance of Form2 in Form1, pass the reference to
itself...

\\\
Form2 objForm2 = new Form2(this);

objForm2.Show();
///

....which enables you to call the procedure in instance of Form1 that called
Form2...

\\\
// Button in Form2

private void button1_Click(object sender, System.EventArgs e)
{
myForm1.myProcedure();
}
///

HTH,
Gary

Open Connection to database, geting from second form from textBoxes
parameters and executing query at database. The same procedure is
executing after run the program.

(sorry for my english :( )

Is the second form a modal form?

If so, something like the following would be better:

class SecondForm : Form
{
//...
public DialogResult ShowDialog(out string a, out string b)
{
DialogResult result = ShowDialog();
a = firstTextBox.Text;
b = secondTextBox.Text;
return result;
}
}

class FirstForm : Form
{
//...
void Foo()
{
string a;
string b;

SecondForm f = new SecondForm();
if (f.ShowDialog(out a, out b) == DialogResult.OK) {
DoSomethingWith(a, b);
}
}
}

On 'SecondForm' you might have 'OK' and 'Cancel' buttons. Their
'DialogResult' properties should be set to 'OK' and 'Cancel', respectively.
 
Since a Form is a class, create the procedure as 'public' and through
the instance of Form1 (create this instance in Form2) as below

Form1 f1=new Form1();

call the procedure from Form2 as below

f1.ProcedureName();

Then the procedure is running in NEW form1 not in existing, I know it,
because I do it.

The problem is corrected, EOT
