apparently i can't do this:

Dim TextBoxArray() As TextBox

Vb.net says "cannot convert type of System.Windows.Forms.TextBox to one-dimensional array of system.windows.forms.textbox"

any idea how i can get something similar to this that would look basicallly the same?

thx

I dont exactly know a lot about this, but from my experience, when it says that, its because it wants you to specify a max.

Dim TextBoxArray(0 To 4) As Textbox
in VB6 and

Dim TextBoxArray(4) As Textbox
in VB.NET

Im not completely sure but that might be the problem.

EDIT:

Actually I just tried what you had, and it worked for me, so I really dont know, thats strange.

oh i figured it out, you have to do


thanks for your help you set me off in the right direction

if you also make a bunch of controls (text-boxes) whatever, with the SAME NAME it'll ask you if you want to create a "command array". then you can be like:

text1.item(1).text = "hello world"

etc.

Doesn't work like that in .NET mate. Crazy, I know.

If you want the textbox to actually be useful you probably want to declare it withevents, and stick a handler on it. You actually can do the VB6 control array handling event (with an index-like parameter), you just need to set the handles dynamically (addhandler). I would suggest sticking this in the object instantatiator (Sub New()) and copying the windows forms designers syntax so as not to run into any garbage collection issues.

i should look into .net a little more then. today in class out teacher was explaining pass by value or reference and i was kind of freaked out about how vb handled it, where you can arbitralily decide whether to do one or the other in the function definition regardless of how the variables or objects are instantiated. my goal is to get through the rest of the vb portion of our class without it erasing any of my good habits from C/C++. shouldn't be hard though, i've only got one more homework project to do cuz i did all the other ones in the first week of class or so. hell, i don't have to do anything till late october.

Before you can put anyting into your array you will have to give it a upper limit eg

Not necessarily: you might want a variable amount of controls (dynamic array + redim or the arrays methods) for some strange reason. Plus it's more memory efficient (you're immediately allocating 6 empty ranges and pointers even without declaring it As New, whereas TextBoxArray() allocates next to nothing).

Ithaqua

Yes, when you decalre the array you dont have to dimension it, but before you can put anything in there then it will have to be a fixed length. Doing it that way will mean you have to redim the array to the approiate length before you can work in it.
