arrays - Will you please help me in my migration to VB.NET from VB 6.0? -

-

this question has answer here:

i read article control arrays of vb6 not present in vb.net , rather, became "collection" or something.... (http://visualbasic.about.com/od/usingvbnet/l/bldykctrlarraya.htm)

now, i'm planning learn vb.net , accept whole new language.

so, "few steps" me migrate, here code vb6:

private sub command1_click()     = 0 9         command2(i).caption =     next end sub  private sub command2_click(index integer)     label1.caption = label1.caption + index end sub

i wonder if program is? let's it's number pad program. i'll explain program does, @ least now...

as can see, have 12... controls? (i'm sorry, i'm still little bit new in terms of programming)... yeh, 12 of them... 11 buttons , 1 label. 1 button, command1, give captions of other 10 buttons command2(index). , when command2(index) pressed, label1's current caption concatenated command2(index)'s index... (it's calculator, let's skip now)

so, teach me version/translation of in vb.net? :) thanks!

just add 12 regular buttons onto form button1 - button12

then create list hold reference these:

private _buttonlist new list(of button)

add buttons list on form_load:

private sub form1_load(sender object, e eventargs) handles mybase.load     _buttonlist.add(button1)     _buttonlist.add(button2)     _buttonlist.add(button3)     'etc. end sub

then can use list access buttons (zero based) index:

    _buttonlist(4).text = "foo"
