yes i want start inside the panel and then move it to full screen.

so thanks but i think i dont asked my question very well!
that form showing perfect inside of panel but i want create an existing instance of form outside of panel. Suppose user enterd data but form is very small and user want see that form full screen. i want create a full screen of a form that added inside of a panel.

So thanks, that is true.
I apologize again.

Oh...You are preacher!!!
Ok, i'm sorry if annoyed you.
Then my question is : want add all of controls in form and controls in panels and groupbox on form to a List<>.

and my code:

private List _get_all_controls(Control c)
{
List lstC = new List();

foreach (Control ctrl in c.Controls)
{
lstC.Add(ctrl);

_get_all_controls(ctrl);
}
return lstC;
}

this code return controls on form only and controls on panel or groupbox dont added to list.

Are you preacher?!!!
Question is clear, I want add all of controls in form and controls in panels and groupbox in a List<>.
If can help me thank you else goodbye!

Ok, i have a FORM with some controls like button, label, panel and groupbox. this code work for controls that parents are FORM and dont work for controls that parents are label or groupbox.

private List<control> _get_all_controls(Control c)
{
List<control> lstC = new List<control>();

foreach (Control ctrl in c.Controls)
{
lstC.Add(ctrl);

_get_all_controls(ctrl);
}
return lstC;
}

i unable to work with linq unfortunatly!

in mathematics we use Derive and Second Derive. but in this case we have a list of points only.

the post was updated

thanks, but i using this.Invoke because this error recieved: Cross-thread operation not valid: Control 'dataGridView1' accessed from a thread other than the thread it was created on.

my question in better form is: how i can when a Please wait window is showing the main window be unaccessible?

yes, of course our images are very simple for example an alphabet letter.

1. corrected
2. i detected all edge points with edge detecting algorithms and i can draw shape with this points but i want detect just a few points then draw the shape.

thanks. it is system.drawing. do you work with high logic font creator? in this program, you can import an image and program detect a few number of points then save this point and when you want, program drawing shape with saved points. I want doing a work like this. thanks

excuse me it work with LEFT JOIN! i forget remove a where statement! thanks

oh, no. in other wise it dont show all of records in person table that have no name!

thanks, but it dosent work. Your query delete all of records in person table that have no name.

i want that: all of person that saved in persons table whether has transaction or not, reported with query. if person have record in transaction table then sum of price be reproted, else if person have not record then zero be reported.

thanks, this is my query: SELECT Person.name, Sum(transaction.price) AS SumOfPrice
FROM Person RIGHT JOIN transaction ON Person.id = transaction.pID
GROUP BY Person.name
ORDER BY Person.name
