When you access a subroutine by one or more other subroutines each time the variables are zeroed like 'n' below. How can I keep n saved so main can increment n each time.

I have created a public shared subroutine in a class file in asp.net 2 (vb.net) web site app_folder.The subroutine retrives some values from a sql database via an sql query and assigns the datareader field values to several variables The problem is I can't seem to assign the variables from the subroutine to the variables and textbox controls in the asp.net page I am calling the subroutine from. The textbox text value just appear blank.By the way, if I response.write the variables in the subroutine they appear populated by the sql data reader.

I am trying to make a simple port scanner to scan a rang of IP's so like 192.168.4.245 to 192.168.5.100. I am using Visual Basic.Net 2010 and am having trouble converting the IP from a String to a Long so that I can increment it and convert it back to a String. For some reason VB.Net 2010 doesn't include the winsock controller and therefore I am having problems finding a method that works similar to inet_addr() which makes conversion much easier. I found an example on one of the forms here

I've been looking into this problem for a few days now and i can't find exactly the code that i want.I want to run a procedure using an incrementing matrix. If the Matrix that was used is correct then the correct matrix is shown.
the process is get first iteration process if incorrect repeat with next iteration correct end the issue is with the iterations and breaking out of them the matrix length, depth and iteration step can vary.
this is best shown in an example
length = 5
high = 3
low = 0
step 1
the iterations should look like

I have created a table with the following fields
loan_id (PK)
loan_date
loan_return_date
loan_user (FK)
i have set the loan_id column to increment in steps of 1, but when i add a column in visual studio 2008 express it auto increments in minus steps -1 -2 -3. it increments in positive numbers?
I have some nested objects arranged like this:
Process
Persons
Workflows
Tasks
So you have one Process. Then multiple Persons can be added to and multiple WorkFlows can be added Process as well. Multiple Tasks can be added to each WorkFlow but I need a way to tie which Person is doing each task. I basically need a way that for each Person added to the Process it, in it's constructor, assigns a Person.ID property that can then be assigned into each Task's PersonID property...
Dim myProcess as New Process()
Dim myPerson as New Process.Person()
myProcess.AddPerson(myPerson)

I am doing a school project (in programming) on security, and i am focussing on MD5 hashing, this is a used way to store passwords, usernames etc. since i can't really be reversed..Now since i know that MD5 hashes are always 32 byte long there must be a limited number of different "hashes" even though 32 chars with 16 combinations each is a LOT of combos..Now, i will try to make a program where you put in a 32 byte hash and then, by using the principle above with limited hash amounts, try to find ANY string that matches the hash.I have already got code on how to create the MD5 hash but i need to know how to make the strings...it should hash:chr(1)chr(2)...chr(255)thenchr(1) & chr(1)[code]
View 4 Replieswhy my counter is not working properly. It starts by counting all of the files in a directory and everything is set to 0 initially at the start of the program. For some reason when I debug it in certain places the counter increments correctly but with no debugging and once it reaches my DoSql function the counter is not set to the correct number of files anymore.. Below is my code, filesRemaining should be initially set to the number of files then decrement everytime.. when I debug this method itself it works fine but say I put a debug point elsewhere or don't debug at all the counter is not right.

I'm trying to weave a .NET performance counter into an application. When I call the incrementBy(value) method on my avg performance counter it is changing the RawValue of my base counter by value as well. I checked the variable names and think everything is correct. Then when I call increment() on my base counter it adds 1 to the rawvalue of the avgcounter as well as incrementing the base counter... adding insult to injury!
In code I'm using two different counters to measure the time a merge sort I wrote takes. I have a instantaneous counter for the elapsed time of the sort and an average counter.
Dim timePiece As New Stopwatch()
timePiece.Start()
MergeSort()
timePiece.Stop()
[Code] .....
I think I may be using the counters wrong, but why does changing the rawvalue of the average seem to also change the rawvalue of the base? i dont think that's supposed to happen.
I am coding an invoicing application. The user should be able to add a new line to the billing section of the invoice by selecting a product from a ComboBox, which subsequently fills out various other fields (price, description, etc) based on the selected product.
My problem is this: When the user adds a product, I would like the program to automatically generate a new line for the next product. It seems like the only way to accomplish this would be to create a new set of controls with an incremented name, i.e. Product1, Price1, Desc1 for the first product, Product2, Price2, Desc2 for the second product, etc. Is this possible, or am I going about it all wrong?
I have a legacy data table in SQL Server 2005 that has a PK with no identity/autoincrement and no power to implement one. As a result, I am forced to create new records in ASP.NET manually via the ole "SELECT MAX(id) + 1 FROM table"-before-insert technique.Obviously this creates a race condition on the ID in the event of simultaneous inserts.
What's the best way to gracefully resolve the event of a race collision? I'm looking for VB.NET or C# code ideas along the lines of detecting a collision and then re-attempting the failed insert by getting yet another max(id) + 1. Can this be done?
I have a piece of JQuery AJAX that calls a VB.NET code-behind (class) that returns string data. It grabs some latest stats on a particular server. Now the code works, but the first time I press the refresh button data is returned and the alert "Refreshed" is shown on screen.
But if I press it again, the alert box "Refreshed" is shown twice, I click again three times! and on and on, until the time-out kicks in.It seems to be coming from the AJAX call and no where else. I'm at a loss at what could be calling this, I've tried deleting the data returned after success but no joy.
function RefreshServer(btn,div,id,ip) {
$('#aRefresh'+id).html("<img src=images/refreshServer.gif border=0 align=absmiddle />");

View 1 RepliesI have an old program written in VB6. I upgraded the program with VB 2008. The updated program works fine except when the program tries to transfer an array to another subroutine. The old VB6 program sends arr(0) as an argument to the subroutine, the address of arr(0) is passed to the subroutine. The array arr() address is the first of a block of consequent addresses one by one, arr(1), arr(2), etc.
Now when running VBnet, the address of arr(0) is not the first of all consequent arr(1), arr(2), etc. It is an isolated number, just like if arr(0) were a variable instead of an array. The addresses of arr(1), arr(2), etc do not exist in the subroutine. [Code]
The variable of y1 passes to the subroutine oK, whilst arr(0) passes also like y1 into an isolated address. So VBnet interprets arr(0) like a variable rather than the first value of a long list. I haven't been able to find out why the above sample does not work. I got stuck in my programming effort, as I cannot proceed to to further development. how the code should be modified to enable the whole array information passing through the subroutine.
Problem is, I need to call a VB.NET function from javascript, no two ways around it. This is a bit harder to find.BTW -- Web/Page methods won't work. I have to be able to reference a listbox and it's selected items when the VB code-behind fires.
