After gathering the Machine names on the (sealed) LAn i am then getting the ip addresses, MAc address and Macine User name of each machine on the LAn..These details will need to be accessed seperately for use in the security testing and i am unsure how best to store the active data (though eventually in a database) Am i best to create a Multidimensinal arrayList or array(bearing in mind that all the data is convereted to "String" (arrays can only store one data type??) The data found on the live network is allways changing making an array a difficult choice? I have read some tutorials mentioning making a structure with the data and storing this in an arraylist but i dont know whether this will make accessing the individual data items (ip,MAc,HostName etc) a difficult procedure?
I want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like
array2(0)... contains a collection of array1 data array2(1)... contains a collection of different array1 data .. and so on
i think i need to make new instances of array1 each loop, but not sure.I dont mind if it uses arrays, or arraylists, or lists, or structure of arrayslists?
I'm trying to sort an array based on a structure but whenever I do this, it basically erases all the data in the entire array.I have verified that the array is populated correctly, it is when using array.sort that everything returns blank.
Public Class frmMain Private strSpark() As String = {"PR214","PR223","PR224","PR246","PR247","PR248","PR324", "PR326","PR444"} Private strBrands As String(,) = { { } } End Class
I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.
I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.
Public Structure MESSAGETYPE_OIP_Login Dim Header() As COMMANDHEADER Dim UserName() As PSTRING
Dim iArr As Array For Each iArr In m_alTabell 'ReDim myArr(16, 11) If i dim iArr(0,0) as string I could do this.ii = ii + 1 iArr(i, constanter.colNames.colValue) =m_objList.GroupItems.Item(ii).ListItems(i).Value'm_alTabell.RemoveAt(ii - 1)'m_alTabell.Add(iArr)
[Code]...
I have a problem with this code. m_alTabell constists of 10 twodimensional arrays. I have some data in them from the beginning. Now I want to add data in each iArr in a_alTabell. This works fine on the first one. But then the trouble starts. It just keeps overwriting the first iArr in m_alTabell. So if i could redim iArr it would solve the problem but i cant do that course it needs to be declared as Array and not "Dim iArr(0,0) as string" since that couses other problems.
Dim allelementds As HtmlElementCollection = MbFacebookBrowser.Document.GetElementsByTagName("span") For Each DD As HtmlElement In allelementds If DD.OuterHtml.Contains("resource") Then TlsResourceComboBox.Items.Add(DD.GetAttribute("InnerText"))
[code]....
As you can see im currently using a combobox as a type of a list which uses index to give certain labels their text I know that there are only 4 indexes when getting the inner text so how can put those 4 indexes into a sort of list without me using a Combobox?
I have two structures Public Structure myResearchData
Public batchName As String Public arraylistRData As ArrayList End Structure Public Structure myResearchSubData Public researchDescription As String
[Code]...
Cleared MyResearchData.arraylistRData for new data to be put in but it also clears the arraylist inside MyResearchDataAList and didn't old the contents of the arraylist
I have an array of people stored in a custom structure array... how can i copy this array to a temp array so that the temp array has all the same values as the original custom array?
I'm currently stuck on an issue regarding declaring an array of type short in a structure and having it default to 'nothing' rather than '0' after ReDim.'Declaring array and setting it's initial size
Private Structure Totals_T Dim sTot_Desc As String <VBFixedArray(10)> Dim iTot_Cnt() As Short Public Sub Initialize() ReDim iTot_Cnt(10) End Sub
[Code]...
When calling m_Totals(0) the arrays returned have 10 records in the arry with sTot_Desc and iTot_Cnt having values of nothing in all records. When I ReDim m_Totals both the variables I declared in the structure(sTot_Desc and iTot_Cnt) are declared as nothing, it's fine for the String but I need the Short I declared to be declared as '0', which is what I thought happens when you ReDim. Can anyone see what's going on here and why it's declaring my variables as 'nothing' rather than defaulting to '0' for the short and ""/nothing for the string?
I am once again struggling with my weekly project. I am assigned to write a program that converts a predetermined english sentence to both french and german. The code is to contain an Array and a structure. Also we have not covered retrieving array data from a TXT file, so we are to hard code in the array data. I coded the structure and the array, I added the array data, but am confused how to access the data. The examples I have found all deal with retrieving data from a TXT file. Can someone give me a nudge in the right direction.[code]....
The more I read my book the more confused I get, as the programming example is not even close to what this assignment is I am to modify my existing project to keep track of an order in an array.
I'm very new to VB.NET and I suppose this is a little big for a first project.I've done the same thing in other languages so I figured it wouldn't give me much trouble.I'm working on a map editor program for a 2D platformer game.The map will be an array of a structure which contains the width, height, and tile elements of each layer. the tile elements are stored in a 2D array within the structure.[code]That didn't give an exception but I'm not sure that it actually redimmed considering the second assignment command still crashed.
I am writing a class and room scheduling program, and would like to use an arraylist that will contain structures. The structure has a couple of arrays in it for when the class meets, and I am having difficulties figuring out the correct syntax to declare the array in the structure. Additionally, in the syntax to access the array. For instance, say I want the MeetingDays to be T, F, T, F, F, F, F; the Meeting Times to be "8:00AM", "", "8:00AM". "", "", "", "", ""; and the Duration to be 75, 0, 75, 0, 0, 0, 0

I'm having a bit of trouble trying to iterate or search through my array (or structure).I am reading in some values from a file, and populating my array.Then, I need to search to compare to one of the values in my array.[code]any pointers? should I use something else instead of arrays / structures ?
I am trying to split an array into a jagged array for easy manipulation, but I am having a bit of trouble with the Copy method of Array.This is what I have:
Dim masterData()() As String = New String(splitCounter.Count - 1)() {} For i As Integer = splitCounter(0) To splitCounter.LastIndexOf(splitCounter) Array.Copy(ServerResponse, splitCounter(i), masterData(i) = New String(), i, splitCounter(i
there are any nifty in-built .net methods that can essentially return either the number of occurrences of each element in an array, or simply return the modal value.
I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin() g.DB("SELECT nameOfPerson FROM Persons") For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.
I am trying to be able to add to an established Array that is read in from a CSV file. I'm using structures and I get the concept, but I just can't seem to get it to store. I am using Visual Basic 2010. Sorry for posting in here, but I did not see a category for it.
I wish to write a structure made up of fixed length strings to a file using y.Computer.FileSystem.WriteAllBytes or the like.I am using a VB6 project with fixed length strings that I have converted in to VB.Net.
Structure Record <VBFixedString(22),System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValArray,SizeConst:=22)> Public tim() As Char
