Howdy,

Im making an app to store my contacts in.

Ive included the ability to copy the details of a selected contact to the clipboard so they can be pasted to a document or email quickly.

However my problem is that im not sure how to go about making my code, so it ignores empty/incomplete data or textboxes.

Currently this contact would come out like this:-
Badger

He's a Beer Drinking Buddy!!!

Open in new window

Becuase its missing data (phone numbers and an address in this case)

It would be much better and much more user friendly if it just came out like -

Heres my code:-

   //Copies Selected Contact to ClipBoard
        private void btnCopyfromclipboard_Click(object sender, RoutedEventArgs e)
        {
            
            Clipboard.Clear();

            if (listNames.SelectedIndex != -1)
            {

                String compareName = listNames.Items[listNames.SelectedIndex].ToString();

                StringBuilder copy = new StringBuilder();
                copy.AppendLine(tbName.Text);
                copy.AppendLine(tbMobile.Text);
                copy.AppendLine(tbSecphone.Text);
                copy.AppendLine(tbEmail.Text);
                copy.AppendLine(tbWebsite.Text);
                copy.AppendLine(tbAddress.Text);
                copy.AppendLine(tbNotes.Text);

                int attempts = 0;

                while (attempts < 5)
                {
                    try
                    {
                        Clipboard.SetText(copy.ToString());
                        return;
                    }
                    catch (COMException)
                    {
                        Thread.Sleep(10);
                        attempts++;
                    }
                }
            }

        }

Open in new window


So, how do I make my app ignore the empty textboxes/data? (im using WPF,Net 4.0)

Many Thanks

John

P.s yes I ran into the clipboard problem so had to dig up a solution from the interwebs, a tutorial in this case, just incase the code looks fmailiar :-)

For every single TextBox, do a check like this before appending:
if (tbName.Text.Trim().Length != 0)
{
    copy.AppendLine(tbName.Text);
}

You could also do something like this:
StringBuilder copy = new StringBuilder();
            List<TextBox> tbs = new List<TextBox>();
            tbs.AddRange(new TextBox[] { tbName, tbMobile, tbSecphone, tbEmail, tbWebsite, tbAddress, tbNotes });
            foreach (TextBox tb in tbs)
            {
                if (tb.Text.Trim().Length != 0)
                {
                    copy.AppendLine(tb.Text);
                }
            }

Hi,

Storing and Retrieving Data

Clipboard has static methods to copy and paste data. The SetDataObject method is used to store data that is in object format on the clipboard. The following code snippet copies selected text from a RichTextBoc control to the clipboard.

Clipboard.SetDataObject(richTextBox1.SelectedText);

The GetDataObject method gets the data that is stored on the clipboard. The following code snippet gets data from the clipboard and displays in a Label control.

// Retrieves data

IDataObject iData = Clipboard.GetDataObject();

// Is Data Text?

if (iData.GetDataPresent(DataFormats.Text))

        label1.Text = (String)iData.GetData(DataFormats.Text);

else

    label1.Text = "Data not found.";

Clear Clipboard

Clear method removes all data from the Clipboard.

Clipboard.Clear();
