I know how to check whether an item exists in a list using (MyList.Contains), But I do not know how to check the whole list. For example (use one button and one richtextbox):

I have two lists. One list is a list of names, the other list is a list of how many times each name is found in the first list noted in the database
so...
Nick
John
Jim
Jack
is the firs tlist
10
13
13
2
is the second list. Nick had 10, john 13 and so on.I want to sort the second list from large to small, but have the index for the first list still linked to the correct amount of calls.i do it this way so I can
for x = 0 to num_of_names
string = lst_name(x) & "-" & lst_count(x)
next x

I am working on a project for software engineering where we are trying to create a warehouse inventory system. I have created an inventory page where I can add/delete/search for an item as well as access invoices and reorder items... i am struggling on the delete item part. I have my design set up where there are four different lists on my page. One for name, one for serial number, one for RFID number and one for amount in stock. I want to be able to select an item by name and its information in serial number, rfid, and amount also select and have no idea how to go about this..I wanted to use four different lists because I need to be able to delete an item from the list and it remove just one from that stock and not the entire item unless there is only one of that item left in stock.
for my inventory page

I have two objects that are derived from same the base class. ets say ObjA is the base class, and ClassB and ClassC inherits ObjA. f I have a dim lst1 as List(Of ClassB) im list2 as List(Of ClassA)nd and I want to check for the existence of something being in lst1 that it is in list2, now I am only interested in comparing against one key bit of information that it is declared in the base class and is a string. How can I iterate through the lst1 comparing against list2? I thought I could I overload/override the Equals method but I am having no joy for either of the classes and say some thing similar to

Dim temp As ClassA = TryCast(obj, ClassA)
If temp.Id = Me.Id Then

I have to retrieve same amount of datas from a variable number of clients in an arraylist. I know I can put arraylists in arraylists but would be easier to get one arraylist for each client dynamically declared.
Ex: alClients (XXX, YYY, ZZZ)

Dim nameVariable = "al"+ alClients(i) ' = alXXX
Dim nameVariable as New arraylist()

In VB6 I could set up code to loop through say 10 option buttons to check their values. The code would be something likie this:[code]But in VB .NET it seems that if I use the Controls command as above I cannot use/check the Checked property as Control does not take that as a property of Control. It seems also that I may have to use the Find property of Control as in "Controls.Find" etc.How can I do this in VB .NET? I have a very control intensive application and I must be able to easily loop through controls and check their values without writing out 10 x the code required.
View 8 Repliesi have used in vba 3 dimensional jagged arrays where i had up to 10000 rows. i am now transferring this to vb.net and learnt that it would be better to work with lists. the dimensions are such as (30, 10000, 30). how would i structure this by using lists?
View 8 RepliesI've managed to make some single dimension array lists but I can't figure out a multi dimension arraylist.
Here's what I'm trying to do:
I have a database (mdb) with 5 columns that I want each row to be in an array list.
In PHP what I'd typically do is:
$array[$field1] = array($field2,$field3,$field4,$field5);
How I do the same in vb.net so anytime I need to fetch an item for a specific for the row1 I could call it?
For a single dimension I could do the following, but I can't figure out how to add more fields to a single array row:
Dim tmpArrayX As New ArrayList
tmpArrayX.Add(field(0))
tmpArrayX.Add(field(1))
etc...
Something like this:
Function SubArray(Buf() As Char, FromChar As Integer, ToChar As Integer) As Char()
I have two array list same size, depending on the information gathered by previous functions. The size of the arrays range from 2 - 45 in length, both arrays always have the same length. I am trying to match one string in one array to another string in the second array. When they match then add Item to List.
Here is my
Do Until i = Arraylenght
info = Replace(myAL(s), " ", "")
SortedArrayList(m) = Replace(SortedArrayList(m), " ", "")
SortedLine = Split(SortedArrayList(m), "Price=")
If myAL(s).Contains(SortedLine(1)) Then

This code works up to an array of not more then 4 in lenght, when working larger size array then 4, the minute it get to 5 I get this Error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I want to pass a List of T where T is an object I've created that has about ten properties (strings, dates and integers).The lst passes to the function successfully. I am also passing an New T of the Object (itm as T).I can see all the values (see image below), but because it's generic I cannot seem to retrieve the property values and I cannot figure out how to iterate through the properties of each itm as they are retrieved in the For Each.[code]

Note: each record line has one sample from each channel recorded. i.e. each record line is a slice of a 32 sensor recordings. I want to build up a x,y list of data points for each channel (the x axis is common to all channels). Is there some way to do it similar to what I have above (avoiding indexing variables).

I'm very new to programing and am having problems trying to perform some calculations with a list. I have read in an array into a list with a count attached to each item example: "xxxxxx(intcount)". What I'm trying to do it use two xxxxxx(intcount)'s at xxxxxx(intcount+5) and xxxxxx(intcount+25) and use these two variables to calculate yyyyyy(intcount) but it isn't working. I understand this may be a stupid question but could someone please point me in the right direction.

I have a web site where users enter company names to use in the rest of the app. However, recently I've noticed that similar duplicates are appearing, e.g. someone will enter EastTec Solicitors another will enter EastTec Solicitors Ltd someone else will enter EastTec Solictors (missed the i out in Solicitors), when there should only be one entry of EastTec Solicitors. What is the best way of checking the database for entries similar to what they have entered? How would you about checking for spelling mistakes as well like the Solicitors one?
