openeing other forms from current form

[hazejean]

I have a situation where I need to open other subform sfrom the currect form.

The number of sub forms and form names will be passed to current form via a text file.

 

Example Form1 reads a text file containing subform names separated by semi-colons

 

example: forma;form123;formx

all three need to be diplayed at once

How about a select case statement? Loop through each item in

the text file and show the appropriate forms.

 

' Add a beginning loop here
Dim frm As Form

Select Case formName ' formName = the form to show's name
 Case "forma"
   frm = New forma()

 Case "form123"
   frm = New form123()

 ' etc.
End Select

If Not frm Is Nothing Then frm.Show()
' Close the loop here

Here's some sample code I whipped up to do it from a string.

        Dim fname As String = "TestProj.Form2" 'The name must be fully qualified (i.e., with the namespace)
       Dim formType As Type = Type.GetType(fname)
       Dim f As Form

       If Not formType Is Nothing Then
           f = formType.InvokeMember(Nothing, Reflection.BindingFlags.CreateInstance, Type.DefaultBinder, formType, Nothing)

           f.Text = "My New Form"
           f.Show()
       End If

Nothing fancy; it just uses the awesome power of the System.Type class to find the Form's base type given the string, and then it uses the base type to create an instance of the form and show it.
