passing value from one form to another
-
can we pass a value from one windows form to another windows form as we do in asp.net (using session or cookies)..???i m using vb.net... for ex i have a main form (form_main) in which i enter a id no in a textbox (tbid).when i press the submit button,another form(form_month) will be displayed which will ask for the monthly break up of the amount collected in the form_main. i want to enter the monthly break up amount along with the id (which is present in the form_main in tbid textbox).how can i insert that selected id value (from the form_main ) into the form_month when i will press the submit button of form_month (since form_month doesnt contain the field tbid..so i cant write the tbid.text value in the nsert query if form_month) i want to save the data of form_main and form_month in 2 different tables with a common attribute id in both table its urgent...any help in this regard will be highly appreciated..

form_month needs to know about form_main In form_month:-
Public Class form_month Private m_FormMain As form_main Public Sub New(ByRef formMain As form_main) MyBase.New() m_FormMain = formMain 'setting a ref to the orig form form_main ' This call is required by the Windows Form Designer. InitializeComponent() ' Add any initialization after the InitializeComponent() call. End SubIn form_main:-Public Class form_main Dim m_form_month As New form_month(Me)in the code for the submit button to open form_month:-m_form_month.Show()in the code for the load event for form_month read the value of tbid:-Private Sub form_month_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim contentsOftbid As String contentsOftbid = m_FormMain.tbid.Texthope this helps Alex -

Instead, you should expose properties, or use delegates, to hide as much detail of your class as possible.
