Question Reference to a non shared member requires an object reference.

[Joe1]

I am receiving this error (reference to a non shared member requires an object reference) when trying to make a previously hidden form visible using the code

ParameterSelection.Show() on a winform called parameterview.

I have tried to get round this problem by using;

Dim frm As New ParameterSelection
frm.show()

But this obviously opens a new version of the window, so the selections made on the previous one are not saved.
Is there any other ways around this problem?

Dim frm as ParameterSelection = Ctype(my.application.openforms("ParameterSelection"), ParameterSelection)

Thanks for your help.

This just now gives an error saying openforms is not a member of My.MyApplication
Any ideas?

 

[Lotok]

Dim variableName as FormName = Application.OpenForms.Item("FormInstanceName")

I typed out the last sample without testing it. Try this one. Removed the My and added .item

Works perfectly. Thanks

It sounds as you haven't enabled application framework for project, which would be a bit weird as it is enabled by default.

Removed the My and added .item

Item is default property and need not be specified, ..OpenForms("name") is valid.

Default form instances has been around since VB 2005, weird again.
