variable form type ... can this be done in VB.Net

[jeff]

I would like to do the following ...

Dim lType as String

lType = "frmReport100"

Dim lFrm as lTtype

lFrm.ShowDialog

basically, I want to be able to create a form of type 'StringValue' ... i
want to use a string value to define the type of form to open.

Can I do this, and how would it be accomplished.

Thanks
Jeff

DoI need to loop through all the forms in the application ?

Jeff,

VBS and VBA are made for that kind of solutions.

In VB.Net it makes no sence because you can forever make a table with your
existing forms and select that.

Perhaps this will assist you.
Sub ShowForm(ByVal FormName As String)
Dim ProjectName As String =
Reflection.Assembly.GetExecutingAssembly.GetName.N ame
Try
Dim FormType As Type = Type.GetType(ProjectName & "." & FormName)
Dim frmObject As Object = Activator.CreateInstance(FormType)

DirectCast(frmObject, Form).StartPosition =
FormStartPosition.CenterParent
DirectCast(frmObject, Form).ShowDialog()
Catch ex As Exception
Console.WriteLine("Oooops")
Console.WriteLine(ex.Message)
End Try
End Sub

Armin,

I thought you did (like me) not like late binding, the method I provid is so
simple.

The name of a class should not matter at runtime, however, if you need it,
have a look at http://msdn2.microsoft.com/en-us/library/k3a58006.aspx
(look for "CreateInstance" on the page)

Yes definately simple - bit slightly hardcoded. Tho an array of types +
late binding = plugin system :-)

Armin,

Yes, I don't like it as long as it is avoidable and can be done with other
programming means. I also expressed it by writing that a class name should
not matter at runtime. Though, I didn't want to conceal the possibility of
reflection. In the end, it's up to the OP to use it or not.
I didn't see Smokey's answer yet when I was answering, and.....

the method I
provid is so simple.

..... I didn't have your 2nd post where you explained what you mean with
"table".

BTW, Hi Cor (and Hi group)! :-)

Cor, even een tip. Ik heb je deze fout al veel zien maken. Jij schrijft
vaak 'forever' wanneer je 'always' bedoeld.
