# Two Dimensional Array "Brain Freeze"

Posted on 2002-04-16

VB EE,
I am new to VB and I need to make a two dimensional array that will have a search feature (Do until Boolean found). I am having trouble with the initial layout.

I have three Brands with product numbers. I have a fourth brand that the numbers correspond to.

I need to be able to select one of the three brands (list box?) and then input a product number (text box). The label caption will then display the corresponding result from the fourth brand.

I just need a hand getting started as my brain is locking up when I try to get this going.

I have started with:

mstrParts(0 To 8, 0 To 3) As String (It needs to be string as the product numbers are alphanumeric)

mstrParts(0, 0) = "A12"
mstrParts(1, 0) = "C41"
mstrParts(2, 0) = "D22"
etc..

After I have all arrays defined, I can't seem to figure out how to get the ball rolling.

Any help would be appreciated.
Thanks.

I don't really understand your data.

You select the brand then enter a part number.  Do you want to search the entire array for the part number or only one column?

Does your data look like this?

Brand1     Brand2     Brand3   Brand4
A123       B123       C123     D123
A234       B345       C124     D321
.
.
.

If so then you need to use a list box or radio buttons to select the brand.  The brand then must be translated into a column number (0-2)

row=0
notfound = FALSE
while (row < numberofrows AND PartNotFound)
if (mstrparts(row, col) = EnteredPartNumber) then
PartisFound
else
Increment row
endif
wend

if PartIsFound then
Display mstrparts(row,3)
else
display "Not such part"
endif

Code is rough but this sounds like a homework problem.  The above algorithm should work.

Try to implement it.  If you have further questions feel free to post the code you have and then ask for more help.

Homework assignment it is.
I am not looking exactly for the answer. Just a little help getting started. That is why I was somewhat vague.

I am trying to learn this, not just complete an assignment.
I think that I will be able to get through this, based on what you have shown me.

I am not going to post more code, because if I can't get it right, I will get help in class.

Thanks for your help.
