Calling forms from a Form

[Stephen Plotnick]

I'm very new to VB.NET, or any VB.

I need to have form1 call form2 which calls form3, etc.

I am able to use oledb in form1 to get the data.

I build all the data for form2 and form3 from form1

I can call form2 from form1 without any probles, all the data is there. I
can change to call to form2 to form3 and all the data is there and I can see
the form with success.

I cannot get form2 to call form3.

I did set up a public class for my forms and was able to get all the data
transferred over and use the formclass.form3 .show() to avoid the green error
indicator but when I execute that step nothing happens. I put a form2.hide()
in there and I do go back to form1. As expected.

Thanks,
Steve

Look, if you want to track down your forms in your application, then
you need to create forms manually and keep the objects and when calling
another form, pass that object to another form by using any public
method.

lemme show u a pseodo code:

Form1
----------
Dim f2 As New Form2()
f2.xxx(f2)
f2.show

Form2
------------
// variable to store f2 objects
Dim myF2 as Form2

// then declare a public procedure

public xxx(ByVal f2 As Form2)
//
myF2=f2
//
end procedure

In that same way u can call Form3 also. If you want to send data to
form2 then just add an extra parameter on xxx().

Thanks,

I initially was going to try that but I could not figure how to get a data
record form the oledb call passed to second form so that it cold be used in
the thrid from, etc.

In My research I found this public class that was supposed to allow me to
populate the data in form3 from within form1 and than do a show of form3
from within form2, and the data elements would logically be there.

I guess what I need to know how to do would be to pass the record in
function xxx and be able to get at the data from within form2 to do the
form3 processing.

To further explain what I am currently doing that does not seem to work I'm
cutting actaul code here.

From a formd called StoreSelection:

Public Class myFormLibrary

Public Shared StoreInformatio n1 As Form

End Class

Also from form StoreSelection;

Dim frminfo1 As New StoreInformatio n1

'Set up values for storeinform1 screen

frminfo1.LegalN ame1.Text = myDV(rowIndex)( "LEGAL_NAME_LIN E1").ToString ()

frminfo1.LegalN ame2.Text = myDV(rowIndex)( "LEGAL_NAME_LIN E2").ToString ()

frminfo1.StoreO wner.Text = myDV(rowIndex)( "STORE_OWNER"). ToString()

From a form called StoreInformatio n that is called from StoreSelection
using;

Dim frminfo As New StoreInformatio n

'Set up values for storeinfor screen

frminfo.LegalNa me1.Text = myDV(rowIndex)( "LEGAL_NAME_LIN E1").ToString ()

frminfo.Show()

From StoreInformatio n I'm trying to see the form StoreInformatio n1 using the
following code, I'm not putting any data in the form here, it was all added
in StoreSelction.V B

Private Sub NextButton_Clic k(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles NextButton.Clic k

myFormLibrary.S toreInformation 1.Show()

Me.Hide()

End Sub

I do not get any errors during compiling or green underlines in the Visual
Studio program. The Me.Hide() does remove the StoreInformatio n form but I
see StoreSelection form instead of the StoreInformatio n1 form.

THanks,

Steve

As you said that VS not giving any error on compilation(inc luding
green-warning), I think its not the coding problem. May be some logical
problem is there.

What is your declaration of "StoreInformati on" ? Is it same as
"StoreInformati on1" as you mentioned as "Public Shared
StoreInformatio n1 As Form" ?

Anyway, I am sure some Object related logical problem is there.

I dont know it'll solve your problem or not but give it a try:

Swap the position of
"myFormLibrary. StoreInformatio n1.Show()"
and
"Me.Hide()"

i.e. first do the Hide thing, then Show()

and 2nd try:

Try using "ShowDialog ()" instead of "Show()"

Thanks for your reply.

The Showdialog and rearranging the order did not work.

Thanks
