Looping Arraylist Adding To Textbox
May 19, 2009I'm trying to do is take each item from an arraylist, that is populated through a structure read from textfiles, then loop through them adding each result from the arraylist to a new line in a textbox. What I'm getting is that it's adding only the last item to the textbox rather than listing them, yes I have multiline set to true. Because of the potential size of the arraylist I have it running in a background worker. Once it's complete then I'm trying to populate the textbox. All the code is working fine to that point it's just populating the textbox correctly is my problem.[code]I've tried adding vbnewline, vbcrlf, cblf at the end of the statement as well as placing the text statement in both the runworkercompleted sub as well as in the delegate with the same result.
View 5 RepliesTextbox AutoComplete - Items From ArrayList
Mar 19, 2008I develop an application in vb.net and mysql server for data storage. I have a problem in my database I have something like 5000 codes stored like code, description, quantity, price, firm. I have a function to extract all the codes from database , it takes about 4,4269 ms to extract all 5000 codes with description and everything... in an arraylist. When I want to put all codes from arraylist in a textbox autocomplete, it took about 2305,400 ms and I think this is a big problem the function to put in textbox autocomplete all the items from arraylist:
Code Snippet:
Public Sub PopuleazaTextBoxDinListaCoduri(ByVal txtbox As TextBox, ByVal list As ArrayList)
txtbox.AutoCompleteMode = AutoCompleteMode.SuggestAppend
txtbox.AutoCompleteSource = AutoCompleteSource.CustomSource
Dim valoare
For Each valoare In list
txtbox.AutoCompleteCustomSource.Add(valoare)
Next
end Sub
This is one item from arraylist extracted from database in this format :
code4993 ->description of code4993(3 buc X 234 lei)

View 3 RepliesAdding Textbox Name And Text To ArrayList Using Structure?
May 20, 2011I have a function which iterates through the TextBoxes in my form (and its child controls) and adds each TextBox's name and text to an ArrayList using a structure I called valTxtBox.
Here's a snippet of the
VB.NET
Public Structure valTxtBox
Public nome As String
Public texto As String
End Structure
[Code] .....
Now, the problem is that if I call Clear() for valsTxtBox in the getctrls() function, not all the elements get added to the ArrayList. However, if I don't call Clear() it works just fine. BTW, I'm using VS2008 express which might be relevant.

View 1 RepliesCopy The List Of Principal User To Arraylist To Use Arraylist.indexof?
Dec 1, 2011What I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.
I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.
Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.
Sub RetAllMbrs(strUser As String)
Dim oPC As PrincipalContext = GetPrincipalContext() '<- this is function somewhere else in the code

VS 2008 - Reading ArrayList In My.Settings And Add Another ArrayList To It
Sep 21, 2010What I need to do is read an ArrayList in My.Settings and add another ArrayList to it. The first think I'm trying to do is load My.Settings.Records into myArrayList. I'm not quite sure on the proper way to do this. I've tried things such as Dim myArrayList As ArrayList = My.Settings.Records, I'm not sure if I need New and I'm not sure if I need .Clone or .CopyTo.
Then I have another ArrayList myArrayList2. To get this into myArrayList I've done: [Code] Then to save it back to My.Settings I've done. My.Settings.Records = myArrayList. The problem is I keep on getting Object reference not set to an instance of an object error on the AddRange line. My.Settings.Records is definitely an ArrayList and it will sometimes = Nothing. The objects will only ever be strings.

View 5 RepliesCreate An Array Of An Array (or Arraylist Of An Arraylist) To Hold Strings?
Mar 20, 2012I 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?
Difference Between ArrayList In VB From ArrayList In C#?
Apr 12, 2012s there a difference between the arraylist in visual basic and arraylist in C#? I had to convert some C# code to VB and there is a call I make in a third party api that requires me to pass in an arraylist. When I do this in C# it works just fine, but when I do this in VB, I just get back a vaque exception from the api.
[Code]...
The exception I get is very vague and comes from the API. All i get is, "ARException Occured".
Show Url In Textbox?
Sep 3, 2009I'm working on a browser, and I can't seem to get it to show the current URL in my textbox. I have tried this code:
Private Sub Form_Load()
WebBrowser1.GoHome()
Url.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).LocationURL
End Sub
But I keep getting the error "'LocationURL' is not a member of 'System.Windows.Forms.WebBrowser'"
I need it so that it changes according to tab. I think it might use the
CType(TabControl1.SelectedTab.Controls.Item(0), code but I'm not sure.
