How can I read values from multiple textboxes into a 2-D array in VB.NET?

[debwaldy]

Hi I am a new-comer to VB.Net & I am working with arrays at the moment.i want to write a procedure that accepts two 2-D arrays(max size being a 4*4 matrix).
i don't know how i could get the procedure to read in these values from the sixteen different textboxes i have created...i started using a for/next loop to go through each row as shown below:

Dim i, j, n, m As Integer
Dim a As Double(,)
a = New Double(i, j) {}
For i = 0 To a.GetUpperBound(i)
For j = 0 To a.GetUpperBound(j)
a(i, j) = TextBox

its here that I am stuck i want it to go through each row of textboxes row by row and read in the values input by the user.would some sort of inner loop again work...or is there a much easier way to do this...any help is much appreciated

Yeah, this is a frustration w/ VB.NET, after such things (called "control arrays") that were so easy in VB6 got tossed out in VB.NET

There ARE ways to create control arrays in VB.NET but it's quite ugly. I suggest a search on one of the VB.NET forums. The details are just too messy for me to want to go into here in a post.
