well, the best way to do it depends on exactly what the relationship between these two forms is.
if form1 is the mdi parent of form2...
'in formTwo...
dim formOne as form1 = me.MdiParent
if form1 is set as the parent control of form2 through the .Show() procedure...
'in formTwo...
dim formOne as form1 = me.Parent
the above code will give you an instance of form1, which you'll then need to utilize to add your control.
my recommendation for doing this would be having a friend Sub to grant access for you to the controls property of the panel.
public class form1
inherits system.windows.forms.form
'--- windows generated code ---'
Friend Sub AddPanelControl(byval controlToAdd as Control, byval location as System.Drawing.Point)
me.panel1.controls.add(controlToAdd)
controlToAdd.Location = location
End Sub
End Class
public class form2
inherits System.Windows.Forms.Form
Private Sub button1_click(byval sender as object, byval e as buttonclickeventargs) handles button1.click
dim formOne as form1 = me.mdiparent 'you may need to cast this return value using ctype depending on whether or not you're using option strict on...
dim newControl as New TextBox
With newControl
.Name = "myTextBox"
.Text = ""
'etc.
End With
formOne.AddPanelControl(newControl, new System.Drawing.Point(10, 10))
End Sub
End Class
This should work out for you. I haven't tested it out or anything, but let me know if there are problems.
I would still recommend setting your controls at design time and just worrying about managing their visibility, but if you can't then this would be another way...

JIM:
Thanks, very close.
this is what I have.
FORM1 has the array of controls (all textbox inside a PANEL1)
lets say:
textbox1
textbox2
textbox3
when we click a control let's say textbox2:
Form2 will overwrite the control textbox2(hide The control from FORM1) and
creating the new Textbox2 (could be any type of cotrol: a textbox or Calendar or whatever) in the location where textbox2 was.
now, FORM2 has to create the control reading from a DB at run time and overwrite the one form FORM1.
If you can give one more tip...THE CREATE STATEMENT
I need to say FORM1.PANE1.CONTROLS.ADD(newcontrol) from FORM2
i DONT KNOW HOW ?
I appreciate your help.
Thanks

forgot!
FORM1(Is not mdiparent) does the call only by:
dim f2 as new form2
f2.loadFld(me,textbox2)
and
FORM2 has:
Public Sub Form_Load(ByVal pf2 As Form, ByVal t1 As TextBox)
|
|
|
|
|
that is what the freind sub AddPanelControl is for. in general it's nota good idea to expose properties of child controls to external resources. therefore a buffer that can control access to an exposed field can limit who, or what can access the exposed field. for instance, since the sub AddPanelControl is declared as Friend, it restricts access to only objects declared in the same project as the procedure.
so from form2 you can AddPanelControl and pass in the newcontrol you want added to the panel. the problem you're going to run into with this architecture is that you're not going to be able to destroy the initial control; or textbox1.
this is why i recommended going with a solution whereby you set everything at designtime and just check a variable state to determine the visibility of certain controls.
honestly, from your description i still don't understand exactly what you want to do.
you have a form 'form1' with a panel and for example several textboxes. when you click on textbox1 on form one you want to have form2 replace textbox1 on form1 with another control? i don't understand how this is going to work... 
am i misunderstanding you?
maybe if you post the relevant code that you have from form1 and form2 i can try to figure something out.

FORM2 (which will be a new project) will handle all the routines for to the new textbox2 (checking and validating).
This is what I need/want to do:
We have 202 forms with diff entry fields for ea reports (CR v10).
These entry fields can be chkbox, list ,combos, and so on.
ea form could have a mix of fields as datefrom,dateto,idfrom,numfrom,numto and many more fields.
Forms can have any of these fields and ea field will have to be validated.
in a case of a IdFrom will have to have a list for the user to select from. I think I can avoid doing 202 forms if...
If I create a general FORM1 with text boxes representing ea field entry, then, when the user clicks on one of the textbox I will know what form to call and handle all the related to such field and validate such field.
So, ea field will have a Procedure to handle all related to the field (err msg,edits,checking range values or any other need).
if we have one form for ea report we have to repeat too much code.
neither, I cannot have all these code in a single form, it will be too much debugging.

The documentation and QuickStart samples with this ApplicationBlock would probably be a good place to start, don't you think?

How do you access a winform in CLASS FORM1 from CLASS FORM2 (form1 is calling form2)?
this is what I would like to do.
FORM1 will have the winform .
FORM2 will have the controls to create at run time...this controls will show on the screen of Form1.
So far what I have:
FORM1 is calling FORM2 as
popForm1.form_load(Me)
and in FORM2 I am trying creating the controls:
Public Sub form_load(ByVal pf2 As Form)
dim NEWCTRL as new textbox
NEWCTRL.name = "ctrl1"
...
HERE IS WHAT i WANT FORM1.panel1.CONTROLS.ADD(NEWCTRL)
the FORM1 has a Panel1 that I dont know how to add my newctrl to FORM1.PANEL1
THANKS

If I understood you want to open a form inside another form, to do this you should set the Form1 property IsMdiContainer to true.
Then I use this code to manage the opening:
Dim MyForm As New Form1
MyForm.MdiParent() = Me
MyForm.Show()
If you want to access from child form to parent : me.parentform.
I'm neewie, I hope not to confuse instead help

thats all about trying...
Yeap, it is correct what you said, but I want to refer to the controls of FORM1 from FORM2.
how do you get to change one of the properties of any control of FORM1 while you are in FORM2.
|
|
|
|
|
just about right...
try to refence Me.ParentForm1.textbox from FORM2...
that's the How do I do that.
what do you pass as a param to FORM2.
|
|
|
|
|
If you want to add a control:
Me.ParentForm.Controls.Add(value as system.windows.forms.control)
------------
If you know the control's name (Textbox1) you can use the for... next as i wrote.
Dim ctr As New Control
for each ctr in me.parentform.controls
if ctr.name="ControlIwantTochange" then
'instructions
ctr.text="Whatever"
end if
next
------------
If you want to change every control:
For Each ctr In Me.Parentform.Controls
Select Case UCase(thisObj.GetType.Name)
Case "TEXTBOX"
'code
end select
next

' Make popup form reference public
' Make Panel Control Public on the popup form
now fom here you can do
popupform.panelcontrol.controls.add (NewCTRL)

Hey Guys
I'm having problems serializing an class that has an object property, even though the object in the instance of that class is serializable. I've cut the code down to demonstrate:
Option Strict On
<Serializable()> Public Class Test
Public Sub New()
End Sub
Dim m_text As String
Public Property Text() As String
Get
Return m_text
End Get
Set(ByVal Value As String)
m_text = Value
End Set
End Property
End Class
<Serializable()> Public Class TestTag
Public Sub New()
End Sub
Dim m_text As String
Public Property Text() As String
Get
Return m_text
End Get
Set(ByVal Value As String)
m_text = Value
End Set
End Property
Dim m_tag As Object
Public Property Tag() As Object
Get
Return m_tag
End Get
Set(ByVal Value As Object)
m_tag = Value
End Set
End Property
End Class
Public Class StartUp
Public Shared Sub Main()
Dim ser As New Xml.Serialization.XmlSerializer(GetType(TestTag))
Dim file As New System.IO.StreamWriter("c:\temp\test.xml")
Dim obj1 As New TestTag
Dim obj2 As New Test
obj1.Text = "TestTag Object"
obj2.Text = "Test Object"
obj1.Tag = obj2
ser.Serialize(file, obj1)
file.Close()
MsgBox("Object Serialized")
End Sub
End Class
Really, all i think all i need to do is change the Tag property of the TagTest class to an type that is know to be serialized, i have tried ISerializable but it don't want to know.
Failing that, i assume i'll just have to implement ISerializable on the TagTest class, but it seems a lot of work just for the one property.
Any ideas greatly appreciated.

Try try tagging the classes <serializable()>.
<serializable()> _
Public Class Test
....
<serializable()> _
Public Class TestTag
....
If that doesn't work you may have to declare the Tag property Test.

according to my understanding ..
if your checkbox array name is chk then you can access it through
you can check the number of check boxes through
chk.length and in for loop
Dim count as integer
for count=0 to chk.length-1
chk(count).checked=true
next

I use vb6.0 to develop a application.
There is two function which could exit from the application.
The first, in menu , close threads and call unload me.
The second, in Form_Unload, just close threads.
The threads is some new operation about database.I have to set nothing to them.
If I exit from menu, all things are good.
If I exit by point the cross on the right above of the form,the form disappear. However , the process is still in the memory. I have to kill it myself.
How to solve the problem?
Thanks!
