Dear Experts,

I am programming in C# and I use VS2010.

I hope I explain this right. I am trying to make a Sticky-Form application.
Just what Microsoft Outlook has. By pressing on a button a sticky-form
appears. But when I change the size of the stick-form and then close the
sticky-form and reopen it, the form has then return to its original size and
position.

Is there a code that I can implement that remembers the size of every
resized form and its position.

You need to record the position ans size before closing the form and set it back to the same position and size when you reopen it.

The best place to record the information is in the application configuration file.

Go to the Project's properties, and in the Settings tab, for each of your forms, create a Size and Location entry. Set it to User level instead of Application. That way it will be read and write, and if many users use the application on the same computer, the data will be recorded separately for each user.

In the FormClosing event to the form, record the settings:

Properties.Settings.Default.Form1_Size = this.Size;
Properties.Settings.Default.Form1_Location = this.Location;
Properties.Settings.Default.Save ( );

Before showing the form later, do the reverse:

Form1.Size=Properties.Settings.Default.Form1_Size;
Form1.Location=Properties.Settings.Default.Form1_Location;

I have test the code but it only works for one form and not multiple forms.

In Outlook it works great. How can I do that in my application.

And this is my code:

        //*------------------------------------------------------------*//
        private void tbNewNote_ItemClick(object sender, ItemClickEventArgs e)
        {
            StickyNotes sticky = new StickyNotes();
            sticky.lblTitle.Text = "";
            sticky.rtbContent.Clear();
            sticky.lblCreation.Text = (DateTime.Now.ToString());
            sticky.FormClosed += new FormClosedEventHandler(sticky_FormClosed);
            sticky.Show();
        }
        //*------------------------------------------------------------*//
        void sticky_FormClosed(object sender, FormClosedEventArgs e)
        {
            StickyNotes sticky = (StickyNotes)sender;
            ListViewItem myItem = new ListViewItem(sticky.lblTitle.Text, 0);
            myItem = lvNotes.Items.Add(myItem);
            myItem.SubItems.Add(sticky.rtbContent.Text);
            myItem.SubItems.Add(sticky.lblCreation.Text);
            myItem.Selected = true;
        }
        //*------------------------------------------------------------*//
        private void lvNotes_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            StickyNotes sticky = new StickyNotes();
            sticky.lblTitle.Text = lvNotes.SelectedItems[0].Text;
            sticky.rtbContent.Text = lvNotes.SelectedItems[0].SubItems[1].Text;
            sticky.lblCreation.Text = lvNotes.SelectedItems[0].SubItems[2].Text;
            sticky.Show();
        }
        //*------------------------------------------------------------*//

another option would be to have FormPersistanceHandler class with information to be persisted like formsize, its location , windowstate etc.
You can make it a Datacontract and its members as datamembers.

In each form that you use this FormPersistanceHandler instance type.

On Form Closing : Update The FormPersistanceHandler instance with latest windowstate, location and size information and serialize it to xml file.
On Form Load : Deserialize the XML File to your FormPersistanceHandler instance and update the form properties with FormPersistanceHandler properties.

Hope this provides you with a prototype of how to implement a solution to your problem...

Yes, BuggyCoder I think that's the solution too. But I have no idea how to do this.

I did not understand that you where always reusing the same class. Since the same form is used for different notes, you would need to have a setting for each sticky note, not for the form. This could not be easily managed.

In Outlook, they do that because when they save the text of the note in the Outlook file, they also save its size and location. You record the text somewhere, isn't it? Then record the Size and Location at the same time. When you reread the text, reread the Size and Location.
