Enable menuitem in parent form from mdichild

G

Guest

I'm trying to enable a menuitem in the parent form from a mdichild. Rather
than making the menuitems public, I'd go for a public method in the parent
form to do the change, but when I call the method from the mdichild, I get
this error:

C:\MyProjects\Visual Studio Projects\Tournament\Forms\frmLogin.cs(69): The
name 'test' does not exist in the class or namespace 'Tournament.frmLogin'

frmLogin is the mdichild.

What am I missing here?

Thanks,
Claus Holm

Hi Claus,
With the info you gave us it is really hard to tell.
What is 'test'?
Are the MDI container and MDI child in the same assembly? If not did you add
a reference to the container's assembly in the child project?
Did you use using statements? And so on. It is best if you perepate some
simple sample code that demonstrates the problem.

Sorry about that, test was the function/sub (I'm coming from VB6), but here's
some more info:

Both forms are within the same namespace. In the parent form I've got

public void EnableMenuOnLogin()
{
mnuSystemSelectSystem.Enabled = true;
}

and in the mdichild, I've got

private void btnLogin_Click(object sender, System.EventArgs e)
{
EnableMenuOnLogin();
}

Thanks once again,
Claus

Hi Claus,

I guess your concerns are about the compiler error that you in that method

private void btnLogin_Click(object sender, System.EventArgs e)
{
// Call from here errors,
seems to be looking locally for the method, not the public one in the other
form
EnableMenuOnLogin();
}

The compiler is right. There is no EnableMenuOnLogin method declared in the
frmLogin class

This method is declared in the MDI container class (frmStrikeTournament
class). To call this method you need a reference to the MDI container object

((frmStrikeTournament)this.MdiParent).EnableMenuOnLogin();

this error:

C:\MyProjects\Visual Studio Projects\Tournament\Forms\frmLogin.cs(69):
The
name 'test' does not exist in the class or namespace
'Tournament.frmLogin'

frmLogin is the mdichild.

What am I missing here?

Thanks,

Thanks, it works. Coming from VB6 it seems strange, that when the method is
public and I'm in the same namespace, it's not accessible after all. Are
there other ways of handling things like this? - I'm thinking in the line of
the using statement?

Thanks once again,
Claus

Hi Claus,

I've no experiance with VB6 and I know that there is big time frustration
among VB6 programmers about the changes made in VB .NET, but I'm still
little bit surprised that VB can compile the code withiout the reference
(see my next answer).

No there is not. *using* is used to save some typing by skipping the
namesapce part of the type names or to give namespaces and types different
names thus, solving name clashes, but in your case you want to access public
instance so you have to give a reference to the object, which member you
call. What if there were two dsitinctive objects (instance of this type)? If
you don't use the reference how can you specify, which object's member you
want to call. How I said I have no experience with VB, but I'm surprise that
it can chew this code
