How to create a pop-up window in VB.net

[nav010]

I am new to VB.net

I want to create a pop up window in VB.net. Whenever I click a button, a pop up window should appear.

Early Response would be appreciated.
Thanks

THis is really basic stuff, i would advise that you do some reading, but here it is anyway:

in the button's OnClick event:

MessageBox.Show(args)

there are something like 21 overrides for the show function, so just have a look for which option is right for you.

Ok, still using the OnClick event, you create your second form in the designer and then call it when the button is clicked:

form2.show()

you can then close the first form...

Good luck

To do this the right way, you will need to instantiate it first:

Dim f2 as new form2()
f2.Show()
 

VB.NET may let you get away without doing that, but it's not proper coding.

Even if you create the form in the designer and add it to the project before calling it?

Of course. Creating the form is creating a class. Classes are the description, the blueprint of an object. In the same way that you define an instance of a String before you can use it, you should have to do the same for an instance of a form. But I think VB.NET cheats for you and automatically instantiates one for you. But it's sloppy programming to rely on that. For clarity and best practices, you should instantiate your forms. Also, in case you ever have to work with C#, or other less forgiving languages, you'll not have problems.

By the way, if you really want it to be a nagging pop-up that makes sure your program can't be used unless the pop-up is closed, you should use ShowDialog instead of Show.

Dim form as new Form()
form.ShowDialog()
