That happens because the ChannelArray variable has not been assigned and it
is Nothing.

can i add new keyword in variable?
Public ChannelArray() As new frmChannel < i added new keyword... does
this help?

No, arrays can not use the New keyword.

If the size of the array is known, you can initialize the array as follows:

Public ChannelArray(10) As frmChannel

Otherwise, you could use an ArrayList class instead, for example:

Public ChannelArray As New ArrayList()

and then use the ChannelArray.Add(...) method.

Apart from the array statements that exist in each language, the .NET Framework provides you also classes that are arrays, collections, dictionaries, queues, stacks, etc. They provide specialized behaviors that are needed sometimes. Take a look at the docs.
