VB.NET - form closing code is not right

hi guys :)

I am still working on this notepad and I am now having trouble with my closing. The closing code is not picking up the fact that the save button was used. In otherwords...I can save my changes, and then hit the X to close the form and the dialog will ask me if I want to exit without saving changes.

here is the closing code that I am using:
not sure what I need to do here at all to fix this. I just know it is not complete...

Your method is correct. It won't magically know that you hit the save button! Here is what you can do. Keep a boolean variable in your class called isChanged. Whenever the user makes any changes to the text set it to true and whenever the user clicks save set it to false. Then in your FormClosing method check if that value is true and only then display the dialog box, otherwise continue with closing the form.

use this code
Private Sub form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

e.CloseReason = CloseReason.UserClosing Then
 Dim answer As Object
answer = MessageBox.Show("Are you sure you want to Exit the Application", "Exit",MessageBoxButtons.OKCancel, MessageBoxIcon.Question)
 If answer = MsgBoxResult.Cancel Then e.Cancel = True
        Else
        Application.Exit()
        End If
    End Sub

good morning Phivos :)

yes I have come across the boolean variable on another form I am making and you are correct..on that form I do not have this issue!

so thank you for pointing me back to this method!

this method is giving me several errors :(

here is the code:
I am being told that Close Reason is not a member, Else must have matching ElseIf, end must have matching endIf, a a end of expression is expected..

Morning Jenn!

Okay, now what am I doing wrong cuz I dont get a dialog box at all now LOL...hit close and it closes! heheheheee O God.

Are you doing anything with the isChanged variable i wrote? Because if you don't set it to true when the user makes changes to the text it will stay false and the dialog box won't show.

Use This Code :

ahaaaaaaaaaa! you were right, I was not telling IsChanged what to do with itself....LOL and stickin it where the sun dont shine was being rejected as a option!

here is the one that worked :)..thank you so much again for your help!

You're welcome!

thank you for your post I did try this method but when I click no..the dialog box stays and will only disappear when I click yes..this quite possibly could be an error on my part, but I did go with Phivos on his recommendations and have it working perfectly now :)

I assumed that you have taken RichTextBox.

there is one Property Modified, you can make use of it, and you can also set its value.

whenever you right in RichTextBox. Modified property returns true. so whenever user formclose then use 

this condition to check whether its modified or not.

for save button: add  one more  statement:

RichTextBox1.Modified = False

 and in form_closing

    Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

 

        If (RichTextBox1.Modified) Then

            If MessageBox.Show("Are you sure you want to exit without saving changes?", "Exiting", _

            MessageBoxButtons.YesNo, MessageBoxIcon.Question) = DialogResult.No Then

                e.Cancel = True

            End If

        End If

       

 

    End Sub
