Question

In the closing event i have this:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            FormIsClosing = true;
            KeysValuesUpdate();
        }

FormIsClosing is a flag.

Then this is the KeysValuesUpdate function:

public void KeysValuesUpdate()
        {
            using (var w = new StreamWriter(keywords_path_file))
            {
                if (FormIsClosing == true)
                crawlLocaly1 = new CrawlLocaly(this);
                crawlLocaly1.StartPosition = FormStartPosition.CenterParent;
                if (FormIsClosing == true)
                DialogResult dr = crawlLocaly1.ShowDialog(this);
                if (dr == DialogResult.OK)
                {
                    if (LocalyKeyWords.ContainsKey(mainUrl))
                    {
                        LocalyKeyWords[mainUrl].Clear();
                        LocalyKeyWords[mainUrl].Add(crawlLocaly1.getText());
                    }
                    else
                    {
                        LocalyKeyWords[mainUrl] = new List<string>();
                        LocalyKeyWords[mainUrl].Add(crawlLocaly1.getText());
                    }
                    Write(w);
                    ClearListBox();
                }
                if (dr == DialogResult.Cancel)
                {
                    Write(w);
                }
            }
        }

The problem is if im doing just if (FormIsClosing == true) the the next line i want not to take effect im getting error on it:

Error 1 Embedded statement cannot be a declaration or labeled statement
And the line after it : dr is unsigned.

If im doing:

if (FormIsClosing == true)
{
                    DialogResult dr = crawlLocaly1.ShowDialog(this);
}

Then dr is unsign on this line: if (dr == DialogResult.OK)

What i want to archive is that if i close my application just dont show this dialog first.
And the line that show the dialog is: DialogResult dr = crawlLocaly1.ShowDialog(this);

Update from OP’s comment

Here’s how you can display the form when the program is not closing:

            DialogResult dr = DialogResult.None;//Increase accessibility domain, setup a good default value
            if (FormIsClosing != true)
            {
              dr = crawlLocaly1.ShowDialog(this);
            }
