[RESOLVED] interface question

hi all,

i created an Interface named IChildCommands.

implemented this in my form.

when executing procedures of this interface, i use

Code:

---

DirectCast(Me.ActiveMdiChild, IChildCommands).Something

---

i'm trying to look for a way to pass DirectCast(Me.ActiveMdiChild, IChildCommands) to an object so that i wouldn't be typing it all each time i want to use it.

i want to do something like

Code:

---

Dim mychild As New Object = DirectCast(Me.ActiveMdiChild, IChildCommands)

---

but the above code is wrong and i only used object as an example. in reality, i have no clue what variable type to use for this.

please help.

thanks.

Of course you use type IChildCommands:

vb.net Code:

Dim mychild As IChildCommands = DirectCast(Me.ActiveMdiChild, IChildCommands)

hi,

thanks for the reply...

i'm having a problem doing the suggested above...

i now have the same thing you have

Code:

---

Dim mychild As IChildCommands = DirectCast(Me.ActiveMdiChild, IChildCommands)

---

but the in the command

Code:

---

DirectCast(Me.ActiveMdiChild, IChildCommands)

---

the bolded IChildCommands is underlined blue and says the "Type IChildCommands is not defined. The intellisense is picking it up though. not sure why it says its not defined.

thanks.

never mind... i figured it out...

it seems that i can't declare it outside of a sub like that.

i had to declare

Code:

---

Private mychild As IChildCommands

---

outside the sub and in the form_load i had to assign it

Code:

---

mychild = DirectCast(Me.MdiParent, IChildCommands)

---

don't know why though.

thanks again..
