[VB .NET] Loading a form on button click

[ribino]

This will probably make you chuckle, but I'm new to VB .NET.

I want to use a command button to trigger the loading of a form. IE, user hits button, and then form appears on screen.

Anyone have any help with this?

Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
 ? ?Dim myForm As New Form1
 ? ?myForm.Show()
End Sub

I think that's right.

Hey there!

Dim [namecanbeanything(1)] as New [formname]

[namecanbeanything(1)].show

Example:

Dim AboutWin as New frmAbout
AboutWin.show

Good luck :)

Thanks you guys so much for fast responses!

Now I just have one more question, how could I pass a variable between forms?

[John Veteran]

That is on the next level of complexity. One method is to create a property on one form, and have the other form call the method/property with the variable to be passed.

That code is quite valid, but you can also do:

Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
   Dim loForm As New Form1
   Application.Run(loForm)
End Sub

I think the "Show" function is there for backwards compatibility with old VB code, i'm not 100% sure though.

Application.Run is for beginning a new application, meaning that the form will have its own message loop. Total overkill. Show() or ShowDialog() are the correct ways of showing a form.
