I have a main MDI form and I have setup the following properties:

• RegistryRepositoryKey = HKEY_CURRENT_USER\Software\Progytech\Card Tracking System\MainDialog
• RememberFormLocation = True
• RememberFormMaximizedState = True
• RememberFormSize = True

Now when I open this form, it will update the registry as follow:

Without doing any change to the Main Form size, I close the application and run it again, then new values are being saved in the registry, causing the form to keep showing up with the wrong height value.

Notice that the SF_FormHeight and SF_FormY values are the one that changed without me resizing the form.  Now this form has an UltraToolbarsManager acting as a RibbonBar and an UltraStatusBar which I believe may be causing this effect, since I do have other projects using the same Main Form without the infragistics controls and does not show this behavior. 

I have the following code in the OnLoad method of the form:

Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
     MyBase.OnLoad(e)
     Dim applicationTitle As String = "Card Tracking System"
     Me.Text = String.Format("{0} ({1})", applicationTitle, My.Application.Info.Version.ToString)
     '-- Set the MDI backcolor to white
     _MDIClient.BackColor = System.Drawing.Color.White
     '-- Add the MDI
     Me.Controls.Add(_MDIClient)
     '-- Create a handle to the CurrentUserChanged event to update the user information shown in main form.
     AddHandler MicroFour.StrataFrame.Security.SecurityBasics.CurrentUserChanged, AddressOf UpdateCurrentUserInfo
     Me.UpdateCurrentUserInfo()
     '-- Set the Connection label on the status bar
     Me.UltraStatusBar1.Panels("sbConnectedTo").Text = "Connected to: " & GetApplicationActiveConnectionStringTitle(ConnectionManager.ApplicationKey, "")
End Sub

This Main Form was created based on the Main Form in the StrataFlix sample, you can see the MainFormSample.png file attached for a reference.

Is there any recommendation to solve this situation?

Sure, I understand, I will create a sample.

Attached please find a quick and dirty sample of my based ribbon project which uses the Infragistics UltraToolbarsManager as a Ribbon UI.

Many of my code has been either commented out or added an "Exit Sub" statement to make the sample functional to show the basic problem of the main form being resized each time the application is run until it will shrink completely.

I added 2 sample forms "First and Second Forms" in the ribbon first 2 buttons, so you can test.

After fixing any missing reference, all you need to do to test is just run the application and exit several times, you will noticed that the main form RegistryRepositoryKey "HKEY_CURRENT_USER\Software\Progytech\Ribbon_Sample\MainDialog" will change all the time the application is closed, and also will see the effect of the main form getting smaller every time it is ran.

Thanks!

I fogot to mention the version I have is NetAdvantage for .Net 8.1.20081.1000.  I was under the impression that if you have a newer version it would be a matter of just changing the references.

So far with other projects in which I am not using the UltraToolbarsManager I have not seen that side effect, so it must definately be related to that object being placed in the form which may be causing the code that saves the form size when closing to get the wrong values.

Maybe you could tell me which and where is the code responsible for saving the fomr's position on the registry and I could probably overwrite that method in the main form in order to debug it and find a fix.

Thanks for the information.  I found the problem in the RestoreSizeAndLocation() method in this line of code:

'-- Set the size
If Me.RememberFormSize Then
     Me.Height = lnHeight
     Me.Width = lnWidth
End If

In this assignment Me.Height will not assume or accept the value in lnHeight, I would guess it has to do with the way the form is instantiated with the UltraToolbarsManager.  Here is what I did:

• Override the RestoreSizeAndLocation() in my main form, of course I had to add the private Constant needed.
• In my Onload, I added a call to Me.RestoreSizeAndLocation() which actually will be run twice and that seem to temporarily fix the problem.  Here is the code:

•  
  Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
       MyBase.OnLoad(e)
       Dim applicationTitle As String = "Card Tracking System"
       Me.Text = String.Format("{0} ({1})", applicationTitle, My.Application.Info.Version.ToString)
       '-- Set the MDI backcolor to white
       _MDIClient.BackColor = System.Drawing.Color.White
       '-- Add the MDI
       Me.Controls.Add(_MDIClient)
       '-- Create a handle to the CurrentUserChanged event to update the user information shown in main form.
       AddHandler MicroFour.StrataFrame.Security.SecurityBasics.CurrentUserChanged, AddressOf UpdateCurrentUserInfo
       Me.UpdateCurrentUserInfo()
       '-- Set the Connection label on the status bar
       Me.UltraStatusBar1.Panels("sbConnectedTo").Text = "Connected to: " & GetApplicationActiveConnectionStringTitle(ConnectionManager.ApplicationKey, "")
       '-- This code is used temporarily until a final solution is available for the main form honoring the
       ' registry saved size and location.
       Me.RestoreSizeAndLocation()
  End Sub

Probably you can suggest a better temporary approach that does not require to overwrite the RestoreSizeAndLocation().
