[VB.NET] Animated Form Extend [SRC]

[Fragma]

The following is an example of how to increase the height of your form & decrease it back to the original size (This example uses a form where Height = 222, and will be increased to Height = 250).

Imports:

Code:

Imports System.Runtime.InteropServices

Function:

Code:

<DllImport("user32.dll", SetLastError:=True)> _
Friend Shared Function MoveWindow(ByVal hWnd As IntPtr, ByVal X As Integer, ByVal Y As Integer, ByVal nWidth As Integer, ByVal nHeight As Integer, ByVal bRepaint As Boolean) As Boolean
    End Function

Using:

Code:

If Me.Height < 250 Then
            Timer1.Start()
        Else
            Timer2.Start()
        End If

Timer1:

Code:

If (MyBase.Width < 500) Then

            Form1.MoveWindow(MyBase.Handle, (MyBase.Left - 0), (MyBase.Top - 0), (MyBase.Width + 0), (MyBase.Height + 2), True)
            If Me.Height = 250 Then
                Me.Timer1.Enabled = False
            End If
        End If
MsgBox("Extended!")

Timer2:

Code:

If (MyBase.Width < 500) Then

            Form1.MoveWindow(MyBase.Handle, (MyBase.Left - 0), (MyBase.Top - 0), (MyBase.Width + 0), (MyBase.Height - 2), True)
            If Me.Height = 222 Then
                Me.Timer2.Enabled = False
            End If
        End If
MsgBox("Retracted!")

This is a really cool effect to add to your applications. Hope you all like it.

This is pretty cool. I never thought of animating the resizing of a form.

I created a module for this (somewhat) although it switches forms, it doesn't only animate their size:
