If say in my datatable i have one column called order number and one column called line. Whats the best way to keep repeating the order number into everyrow, whilst incrementing the line number until i add a new value in the order number column.
So it'd go like this..
Order#______Line
4568________1
4568________2
4981________1
My application does some intensive tasks on a second thread, while updating the main form. I want to show how long these tasks have been running (increments every second), i've read timers can get out of sync and even fire off multiple ticks at once, so how can that be fixed, or what's a better solution for this?

View 3 RepliesI have a program in accounting that is used by many clients and users at the same time in a network. Many modules have a reference no. like in the receipt that increments upon saving, it also Checks whether that reference no. is already in used.
However problem arises when the many users use the same module at the same time. My question is How do you manage incremental values on each client's PC? Their local system somehow competes for the next incremental no.
I want to create hypothetically infinite array lists each that can hold hypothetically infinite items. The name of the array list is "arraycalc". How can I perform a procedure that will create a new array list called "arraycalc1"... the next time after that the procedure is run and a new array list called "arraycalc2"...and so on and so forth.

I am trying to implement a progress bar which increments based on a For Next Loop. The idea being that the increment should occur prior to the next go around of the loop.

I need to create a table with just 1 column containing times (starting from 4hrs) which increase in increments of 10 seconds for each row. So it needs to look something like this:
04hrs 00mins 00secs - 04hrs 00mins 09secs
04hrs 00mins 10secs - 04hrs 00mins 19secs
04hrs 00mins 20secs - 04hrs 00mins 29secs
.....
06hrs 59mins 50secs - 06hrs 59mins 59secs
This will obviously take a long long time to hard code so I'm looking to create it dynamically. Based on what i'm currently trying to learn I'd like to be able to do this using jquery or asp.net (vb) but anything will do as long as it works!

I have 16 cities (those would be my string variables, right?) that I want to appear on my 16 labels in random order without repeating when I click the button. So basically label 1 can be any of my 16 cities, label 2 then will be any of 15 left available cities, and so on and so on.

I'm working on a Bingo game that generates a random letter and number.
Dim RandN As New Random()
Dim randnumber = RandN.Next(1, 30)
Dim RandL As New Random()
Dim randletter = RandL.Next(1, 5)
All that works, but I'd like it not to repeat a combination. Any tips on how to do that?
Also the random numbers tend to be repetitive and the random letter is never 5. I think the random number has been 30 before but I can't be sure. Is there a way to fix that or just a better way to do the random numbers?
there are 8 text boxes where user should put 8 answers, but when he type one answer in one text box it cant be found in some other text box.Basically when button is clicked there should be check for repeated answers.

View 24 RepliesI have built a blog platform in VB.NET where the audience are very young, and for some reason like to express their commitment by repeating sequences of characters in their comments.
Examples:
Hi!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
LOLOLOLOLOLOLOLOLOLOLOLOLLOLOLOLOLOLOLOLOLOLOLOLOL
..and so on.
I don't want to filter this out completely, however, I would like to shorten it down to a maximum of 5 repeating characters or sequences in a row.I have no problem writing a function to handle a single repeating character. But what is the most effective way to filter out a repeating sequence as well?This is what I used earlier for the single repeating characters

sb.Capacity = str.Length

I have a networkstream (using C#/VB.NET). while on reading values coming like this:
&% 68 kg K A&% 23 kg K A&% 174 kg K A &% 68 kg
&% 34 kg K A&% 2334 kg K A&% 68 kg K A &% 68 kg K A
&% 2348 kg K A&% 78 kg K A&% 28 kg K A&% 68 kg
The numerical(weight) value will be continuously varying.
Every time i am reading the starting of the stream differs. But the pattern remains the same. How to split that into '&% 78 kg K A' which represents one set.
How to extract the weight value from this stream using Regex or any other methods?
I need to count number of repeating and position where they repeat of all number in multidimensional array like this:

And result need to be:

Number 2- one time on position 1, two times on position 2, one times on position 3
Number 3- 0 on position 1, one time on position 2, 0 on position 3

i just want to know if there is a way to implement constraint for parameters with a repeating pattern. For that i meant something like this
ParamArray pattern as Integer()
if i need an integer, and any amount of the "pattern" (the pattern here is one integer). so basically the pattern accepts 1 integer and multiples of 1 integer, meaning 2 integers, 3 integers so is there a way to upgrade this so we can have this pattern:
Integer, Boolean
and any valid combinations for this pattern will include
Integer, Boolean, Integer, Boolean
Integer, Boolean, Integer, Boolean, Integer, Boolean
etc, etc
currently the only way i can think of is to wrap Integer and Boolean as 1 object and apply pattern 1, but i was searching for a better alternative?
I have an array that hold 6 random number, then this numbers are sorted from smallest to highest. My question is: How would I go about replacing any repeating numbers with a different random number. I.e. 1 3 7 2 2 9 is sorted into 1 2 2 3 7 9, but I would like to see one of the 2's replaces with a different number (that it is not currently in the array).
I have no code for this part - but the code for making the random number, storing them and sorting them works fine.
Basically I have 7 labels on a form that I randomize into numbers between 0 and 49. However some of the numbers repeat, like this 1,4,8,14,14,50,12. [Code]
View 2 RepliesI have a combobox that I am populating with the contents of a dataset (from an access database). The field that it is showing has lots of values that repeat. I want to remove the repeats of the data so that only unique records are shown in the combo box. I imagine this can be done with the SQL for the data adaptor? I tried: "SELECT type FROM products GROUP BY type" and "SELECT DISTINCT type FROM products" but both still showed the repeating records.
View 8 RepliesI am currently creating a vending machine program, designed to simulate a vending machine. However I have come across a rather large error, my stock is 50 at the begging. The person can go though the program and the appropiate amount of stock is taken away from the relavent object, however when I finish and want to go back to the start the last selection is still present.Therefore I have tried setting the variable as 0 when the form opens and when the program starts, but the last selection is still present.Does anyone know of a way to which I can reset this calculation without affecting my stock so I can then repeat my program cycle one or two times each time using the previous stock without reseting back to 50

I'm trying to figure out the best way to approach this. I have a BackgroundWorker which is being used to make a socket connection on a timer.
[Code]...
edit: thinking about it. It would be good if I could somehow build a watchdog into it, so if the BackgroundWorker thread is found to be running for more than 2 seconds, it's terminated as this would indicate the thread has been held up by the tcp connection.
