  Thanks for your reply

  As I said I am begginer in VB.NET.

  1.How can I impliment the MDI.

  2. When parent and child both of them are open, when I click on parent form the child form go behind the parent form.

  how can i set the child form to remain on top although I click on parent to open another form from the menu.

  thank you very much

  You simply need to create a single project and then simply add the forms to the same project instead of a separate project for each form, unless each form is a self contained application (exe) which you are trying to call.

  If this is the case then you can use system.Diagnostics.Process.Start (<filename>) to start the executables. Although for what youve described it sounds like you should be creating a single project containing multiple forms rather than multiple projects.

  Add a control to the main form for the menu's (in 2005 this is a menustrip, but I seem to recall a similar control in 2003).

  Use the Designer to add the menu items that you want to appear

  In the designer - double click the menu item which will bring you into the code window / event for this click

  Add the code to create a instance of a new form you wish to display

  The code will look something like

  Public Class Form1

  Private Sub ExitToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitToolStripMenuItem.Click
  Me.Close()
  End Sub

  Private Sub Form1ToolStripMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Form1ToolStripMenuItem1.Click
  Dim x As New Form3
  x.Show()

  End Sub

  Private Sub Form2ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Form2ToolStripMenuItem.Click
  Dim x As New form2
  x.show()
  End Sub
  End Class
  

  The code highlighted is the code to create and display new instance of forms.

  When you run this and click on the menu items on the main form new instances of the child forms (form2 and form3) will appear.

  If you wish to have the form displayed modally then use showdialog.

  If you want to use standard system dialogs such as file save, file open and folder browser there are specific controls which you can use to get this functionality and avoid having to code this yourself.

  Hope this points you in the general direction.

  You can specifically set the form sizes or you can implement an MDI solution which will mean the child forms are contained within the parent form.

  Thank you very much for your help

  I understood and added more forms in the Same project.

  Now I have linked the menu item to a form, when I click on the menu item it open the form biger than the size of parents form.

  How can I set the parents form and avoid this.

  thanks

  In MDI - the child forms are contained within the main form.

  Examples of creating MDI applications

  Have a look at these and see if these are what you looking to achieve.
