Save Windows Form Size - windows

Question

I'm developing a piece in VB.NET. Inside my primary form, I'm creating a new form to use as a dialog. I was wondering if there was a way to, upon the close of the new dialog, save it's size settings for each user (probably in a file on their machine, through XML or something?)

Answer 1

you can save it to the settings file, and update it on the 'onclosing' event.
to make a setting goto Project Properties ->settings -> then make a setting like 'dialogsize' of type system.drawing.size.
then do this in your dialog form:
Public Sub New()
InitializeComponent()
End Sub
Public Sub New(ByVal userSize As Size)
InitializeComponent()
Me.Size = userSize
End Sub
Protected Overrides Sub OnClosing(ByVal e As System.ComponentModel.CancelEventArgs)
MyBase.OnClosing(e)
My.Settings.DialogSize = Me.Size
My.Settings.Save()
End Sub
do something like this to check and use the setting:
Dim dlg As MyDialogWindow
If My.Settings.DialogSize.IsEmpty Then
dlg = New MyDialogWindow()
Else
dlg = New MyDialogWindow(My.Settings.DialogSize)
End If
dlg.ShowDialog()

Although this is for C#, it will help with VB.Net as well.

You can also add a new setting to your application (size) and set it to system.drawing.size
Then, you make sure you save the current size to settings on close.
Private Sub myForm_FormClosing(ByVal sender As System.Object,
ByVal e As System.Windows.Forms.FormClosingEventArgs) _
Handles MyBase.FormClosing
My.Settings.size = Me.Size
My.Settings.Save()
End Sub
and on load you apply the size you have saved in settings
Private Sub myForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
' if this is the first time to load the form
' dont set the size ( the form will load with the size in the designe)
If Not My.Settings.size.IsEmpty Then
Me.Size = My.Settings.size
End If
End Sub

Here's a solution that I found online that seems to work rather well for me.
Some of the previously mentioned solutions weren't working for me as expected. Depending on where my form was positioned at the time of closing the form wouldn't get repositioned back to that exact location when I would load it again.
This solution seems to do the trick by taking into account some other factors as well:
You need to set up these two setting under Project Properties -> settings: WindowLocation and WindowSize like so:
Then create the following function:
Private Sub LoadWindowPosition()
'Get window location/position from settings
Dim ptLocation As System.Drawing.Point = My.Settings.WindowLocation
'Exit if it has not been set (X = Y = -1)
If (ptLocation.X = -1) And (ptLocation.Y = -1) Then
Return
End If
'Verify the window position is visible on at least one of our screens
Dim bLocationVisible As Boolean = False
For Each S As Screen In Screen.AllScreens
If S.Bounds.Contains(ptLocation) Then
bLocationVisible = True
Exit For
End If
Next
'Exit if window location is not visible on any screen
If Not bLocationVisible Then
Return
End If
'Set Window Size, Location
Me.StartPosition = FormStartPosition.Manual
Me.Location = ptLocation
Me.Size = My.Settings.WindowSize
End Sub
Next, you'll need to add code to your form's load and closing events like so:
Private Sub frmMain_Load(sender As Object, e As EventArgs) Handles MyBase.Load
LoadWindowPosition()
End Sub
Private Sub frmMain_Closing(sender As Object, e As CancelEventArgs) Handles Me.Closing
My.Settings.WindowLocation = Me.Location
My.Settings.WindowSize = Me.Size
End Sub
I hope that helps.

You can also do this using the UI provided by the VB.NET IDE itself. In the properties pane for a form, look under the item called "(Application Settings)" and then under "Property Binding." You can bind just about every property of the form (including size and location) to a settings value for that application.

As it turns out, I found a way to do this using the System.IO.IsolatedStorage
