Run a Form with a String Variable

Hi All,

I have multiple forms created and my question is if it is possible to show a from via a string variable, something like this.

Normal:
Dim frmtest As New frmRegistry
frmtest.ShowDialog()

Something like this:
dim runform as string = "frmRegistry"
Dim frmtest As New runform
frmtest.ShowDialog()

Or should I do this on another way.

Thanks,
AXH

Yes you can use the Activator.Createinstance method to create objects from strings, but the string has to be the full namespace.

VB Code:

'if you have option strict on then you may have to declare it as an object instead of form
Dim frm As Form=Activator.CreateInstance("MyNamespace.frmregistry")
frm.ShowDialog

Here is an example from MSDN: http://msdn.microsoft.com/library/de...et10082002.asp

This is the error message:

Value of type 'String' cannot be converted to 'System.Type'.

With the following code:

Dim frmname As String = "frmRegistry"
Dim frm As Form = Activator.CreateInstance(frmname)
frm.ShowDialog()

As I said the string must be the full name of the object including namespace. Try reading the MSDN article for more information.

Your project automatically has at least a root namespace so 'frmRegistry' is not the full name of the form.
