Conversion problem from visual studio 2010 to visual studio 2015

I may be mistaken but I suspect that the difference is that vb 2015 programs will be consistent with the Windows 10 styling, including the larger title bar. Whereas vb 2010 programs will be accessing older libraries and their styling is therefore consistent with Windows prior to Win 10.

You could therefore hide the title bar and replace it with a user control that has the height that you need. If you also nee the functionality of the title bar (Minimise, Maximise, Move the window, Exit etc. then you'd have to add that functionality back in with your own controls.

1. Remove the window title bar by setting the `FormBorderStyle` property of your form to `None`. This will remove the title bar along with the minimize, maximize, and close buttons.

2. Create custom buttons and use the appropriate methods to minimize, maximize, and close the form. To move the window, you can handle the `MouseDown`, `MouseMove`, and `MouseUp` events.

3. This is a very low quality example just to show how it works, you'd need to do it more seriously if you go down this route. For instance, you might want to add checks to ensure the form doesn't move off-screen. Also, consider the user experience when designing your custom title bar, as it will not behave exactly like a standard title bar. For example, double-clicking to maximize will not work unless you implement it yourself.

Public Class Form1
    Dim drag As Boolean
    Dim mousex As Integer
    Dim mousey As Integer

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
    End Sub

    Private Sub Form1_MouseDown(sender As Object, e As MouseEventArgs) Handles MyBase.MouseDown
        drag = True
        mousex = Windows.Forms.Cursor.Position.X - Me.Left
        mousey = Windows.Forms.Cursor.Position.Y - Me.Top
    End Sub

    Private Sub Form1_MouseMove(sender As Object, e As MouseEventArgs) Handles MyBase.MouseMove
        If drag Then
            Me.Top = Windows.Forms.Cursor.Position.Y - mousey
            Me.Left = Windows.Forms.Cursor.Position.X - mousex
        End If
    End Sub

    Private Sub Form1_MouseUp(sender As Object, e As MouseEventArgs) Handles MyBase.MouseUp
        drag = False
    End Sub

    Private Sub btnClose_Click(sender As Object, e As EventArgs) Handles btnClose.Click
        Me.Close()
    End Sub

    Private Sub btnMaximize_Click(sender As Object, e As EventArgs) Handles btnMaximize.Click
        If Me.WindowState = FormWindowState.Normal Then
            Me.WindowState = FormWindowState.Maximized
        Else
            Me.WindowState = FormWindowState.Normal
        End If
    End Sub

    Private Sub btnMinimize_Click(sender As Object, e As EventArgs) Handles btnMinimize.Click
        Me.WindowState = FormWindowState.Minimized
    End Sub
End Class

4. `btnClose`, `btnMaximize`, and `btnMinimize` are your custom buttons for closing, maximizing, and minimizing the form, respectively. You'll need to add these buttons to your form and wire up the `Click` events.

5. The `Form1_MouseDown`, `Form1_MouseMove`, and `Form1_MouseUp` methods handle moving the form when the user clicks and drags the form. The `drag` variable is used to track whether the form should be moving.
