Saving srting problem

Hi all,

I am using visual studio in form mode where i have a textbox, a button and a label. When the user insert a value in the textbox and the button is pressed, the value will be saved in integer X. when the form is closed the value in integer X is saved and it is re-loaded in integer X when the form is loaded again. The value is then displayed in the label to confirm that the value is being saved.

For some reason the label is not changing (i.e. stays as Label1), which indicates that the integer isn't being saved or re-loaded.

Can someone please guide me where is the mistake please??

Below is the saving code:

Code:

---

        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
        {
            string get = X.ToString();  //convert integer "X" to string "get"

            Properties.Settings.Default.test = get; 
            Properties.Settings.Default.Save();           
        }

---

Below is the re-loading code:

Code:

---

        private void Form1_Load(object sender, EventArgs e)
        {
            string get;

            get = Properties.Settings.Default.test;
            label1.Text = get;
        }

---

I also included ' using testing.Properties; ' at the beginning of the coding.

Attached is a settings screenshot.

Any help would be appreciated.
Thanks in advance.

Are you forgetting to set value X when they click the button? Something like:

Code:

---

private void button1_Click(object sender, EventArgs e)
        {
            Int32.TryParse(txtBox.Text, out X);
        }

---

What you have should work.

If you're going to use TryParse, you should always check the result:L

Code:

---

if( !Int32.TryParse(txtBox.Text, out X) )
    MessageBox.Show("Hey!  That's not valid!");  //Some error message

---

Otherwise just use

Code:

---

X = Int32.Parse(txtBox.Text);

---

Which will throw an exception if you can't parse the string. Obviously, in code dealing with user-input the TryParse-and-check method is better than the exception handling method.
