Hi,
how can I access / set properties of controls in other forms.
i.e. mdi parent of mdi child
mdi child of mdi child
mdi child of mdi parent

Thanks
Alex

Hi Alex,

You need to have a reference to the other Form.

Each child has an MdiParent property which is nice and straightforward.
The parent Form has an MdiChildren collection which you'll have to rummage
in to find a specific child Form.

Fergus

Fergus,
hmm... I have a status bar in the MdiParent and from the child calling
Me.MdiParent.stBar.Text = "some text" gives me the error

stBar is not a member of System.Windows.Forms.Form.

What am I doing wrong ?

Thanks
Alex

The type of Me.MdiParent is System.Windows.Forms.Form. stBar is not a member
of the Form class. If the type of the child will always be the same, you
can use type casting:

Directcast(Me.MdiParent, <type name of the container>).stBar.Text = "some
text"


IMHO, the better approach is to raise an event in the child and catch it in
the MdiParent. In the event handler the parent sets the text of the statusbar.

Hi Alex,

Ah yes, thanks for reminding me.

Me.MdiParent <will> give you correct parent Form but the Type of MdiParent
is plain old Form, whereas the actual Form is a derivation -
AlexesWonderfulAppForm, so the Controls are 'hidden'.

You'll need to cast the MdiParent to get at the additional properties.
Dim MyMainMan As AlexesWonderfulAppForm
MyMainMan = DirectCast (Me.MdiParent, AlexesWonderfulAppForm)
MyMainMan.stBar.Text = "Yo, Dude!!"

You can, of course, do all that in one go:
DirectCast (Me.MdiParent, AlexesWonderfulAppForm).stBar.Text _
= "Yo, Dude!!"

Fergus

Make sure that stBar is either a property in your form class, or make the
variable public.

All,
Thanks for the help. problem is solved

Hi Chris,
I have seen a lot of Fergus code, but making a variable just public,
somewhere alone on the top of his program.
I don't believe he likes that.

Hi Cor, Chris

'Tis true, although I'll do it for expediency in some cases. ;-) I'll even
suggest it in an answer, if I think that the OP is inexperienced and would
reject the 'better' approach as being too complicated, or if I think that
expediency is their priority.

However, in this case the StatusBar is Friend which is visibility enough.
The problem is that MdiParent Property is of Type Form and doesn't have the
StatusBar.

Regards,
Fergus

Fergus,
as you seem to be the expert here :-) , how can I access the status bar
from a class that is called by a mdi child. i have implemented a class
that reads a file and i want to update the status bar from within that
class.

the direc cast me.mdiparent does not work ...

Thanks
Sorry , question might obvious... just started in vb.
