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
i'm doing this for auto incrementing i called the last value in a row from a database for say, its p-0004 what i wanna do is take p-0004 and add 1 into it to make it p-0005 sorry for my stupidity, i tried using the trim method i used in vb 6 but there was an error like "read only property" something

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
Code: Private Sub Command1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Command1.Click
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.
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
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?
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 do have a table with 3 cols, 2 of those will visible for users to enter data, the last one is needed to get inserted as the next number of the previous number.
i use the following query for insert command ,
INSERT INTO [Headers] (GrpId, GrpName, Number) Select (Select Case when Max(GrpId) = Null then 1 else Max(GrpId)+ 1 end from [Headers]),
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]
why 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.
'Declare global variables Dim fileNumber As Integer = 1 Dim arrayPosition As Integer = 0 Dim changeType As Integer = 0
I am trying to replace tasks.IndexOf(t) + 1 with something a little simpler. Is there any built in functionality for this? Hrmm xml literals do not seem to translate well on here....
I have code that increments an array of numbers. However, due to performance issues, I need to optimize it. Here is the code: Public Sub increment(ByRef Index() As UInt16) Dim N As Integer = Index.Length - 1 If (Index(0) = 65535) Then Index(0) = 0 [Code] .....
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.
1. Write a Visual Basic Console Application.Inside the main procedure call a function procedure to input and return a value for a double variable called x, the width of a right triangle.Inside the main procedure call the same function procedure a second time to get a value for a double variable called y, the height of a right triangle.
2. From the main procedure call a function procedure which calculates and returns a value for the hypotenuse equal to the square root of (x squared + y squared).You will have to pass the values of x and y to this function procedure.The procedure should calculate and return a double type value.The value that is returned by this function procedure should be equal to the square root of (x squared + y squared).
3. Also from the main procedure call a sub procedure to display the values of x, y, and the hypotenuse.
In a tic tac toe game I am making there are two blocks of code that are identical except that they access different arrays:[code]Arrays plyrTaken and plyrPairs are used in the first block and cmptrTaken and cmptrPairs are used in the second. Is it possible to wrap these blocks into one Sub Procedure passing the different arrays when the procedure is called?
i have some problem for developing the code for addtion of 3x3 matrix class the code which i have develop is given below. but this class is not executed in vb.net code. dont know whats getting wrong in it as m nt getting the required result. in correcting the code as m new in vb.net.
I want to generate a matrix (7,4) with this output: (7lines and 4 columns) that has this structure(with this values)Column A1 and row B1 has 2 values (1 8 ), column A2 has 2 values (2 7 value in column A2) , column A3 has 3 6 value column A4 and row B1 has 4 5 value. And so on.How I can generate this matrix: [code] So my question is which condition to put to generate this matrix of this form.A cell A1,B1 contains two values (1 and 8 for example in cell B1).

It is a Class made with the Add Windows Forms Menu.I have another Form where I added from the ToolBox the DataGridView Item. Everything till now works like a charm, the problem comes when I try to load the matrix (previously posted) into the DataGrid. I search for the matrix via DataSource Button (from DataGrid's Properties) but I can't find it, it'll only show up the other forms. I don't know what I'm doing wrong.
So I'm developing a minesweeper game and i've assigned the mines, but I've got to generate the numbers around them. I've already developed the code, but it doesnt seem to be working.It's important to refer that I'm using a DataGridView.Here's how my code looks like now:
