VS 2005 :: Displaying Contents Of ArrayList?
Apr 2, 2009
I am having a problem displaying a custom array list I have in my code. (BTW. It is 1am where I am. I have been at this for a long time so I apologize if I don't make a lot of sense).I built an arraylist of objects from a custom class. The arraylist contains 2 columnsdimensions.The first is type string, the second decimal.I am now attempting to take my arraylist and display it in my form. I have tried using a listview and iterating through it, but unsure of how to split the two columns up. I have tried something similar to the following I found in another forum:
Code:
For i As Integer = 0 To arSearchArray.Count - 1
Dim item As String = CType(arSearchArray(i), String)
[code].....

I am trying to display the contents from a datagrid into a textbox, there are two collums that I want to display. I can get one collum to display by using the following code.
txtCollumone.Text = DataGridView3.CurrentCell.Value
but I want to display (from the same row), collum two.

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 having a hard time displaying the contents of a text file that i read into an array. I read the text of the text file into an array but then i need to display it but i can't seem to get it. I also need to create a criteria to match whatever letter is entered into the textbox and display the contents of the file only beginning with that letter. I know i have to use a substring to read only the first letter but I can't even display the contents of the file from out of the array. Here is what i have so far.
Dim sr As IO.StreamReader = IO.File.OpenText("CRAYONS.TXT")
Dim color(50) As String
Dim arrynum As Integer

Recently I have browsed the web for ways to display a list of files and folders in a list box. I have successfully been able to display files in drive C and get a nurerical value telling how many files were found. However my efforts have been hampered by three distinct problems. I have some experience using batch files and when using them you can state things like "%WINDER%" to go directly to windows folder. I am wondering if there's anything like that used for navigating. And if so could an example be made of it just for clarity?
My second problem is I cant seem to be able to display files and folders. I have been limited to one or the other. That and I cant figure out how to navigate into them to display there contents. The next problem I have is simply having a user interface so you could type a file path or file extention and have the program navigate to it. Is it is possible to click a file path in a list box and chose to delete it. My second last Q how do I display all files and folders including hidden files? And How can I count all files and folders with there contents to dissplay in a listbox.

I'm working on a site that I've inherited that's built with ASP.Net, which I'm only slightly familiar with. One of the pages allows for a link to a document (word or pdf) that, when clicked on, prompts the user to save or open the file, but does not reveal the true path of the file. This way it prevents users from pasting a url to a file - the link is to an aspx file that checks for a valid session, and then retrieves the file.
Anyway, because there's a lot of legacy code, I need to do this with a bunch of static htm files as well, however these files need to be displayed rather than prompting the user to save them, which is what happens now. I tried changing the content type to application/text, application/html, text/html, etc. and that didn't work, then tried adding a response header of content-disposition inline. When I do that, build, and try linking to the file, I get a couple of runtime exceptions:
[FormatException: Input string was not in a correct format.]
Microsoft.VisualBasic.CompilerServices.Conversions.ParseDecimal(String Value, NumberFormatInfo NumberFormat) +206
Microsoft.VisualBasic.CompilerServices.Conversions.ToLong(String Value) +110

Do I have to do something with an htmlwriter object or something? Can't I just have it open a new browser window with the file displaying or does it have to prompt the user if used in this way??

I'm working on a desktop replacement project and was wondering if it possible to have a form which can be docked to the side of the screen that contains all the task tray icons and functions (I would imagine that the functions are held within the task tray/icons themselves as they act as little programs) and would update automatically whenever anything is added.
Also, I'd like it not to have a taskbar entry while running, just having it sit there on the screen until needed.

What 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

What 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.

I've created a windows form with lots of combo boxes and print and save buttons.
I would like to be able to save the contents of the populated combo boxes, labels etc ie the whole form from the save button, preferably to excel 2003. However, would be just as happy to save it in the form format.
The only code behind the save button I have so far is this, which just navigates me to the directory. When I enter a filename and extension, the directory is empty:
Private Sub save_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Save.Click
' Displays a SaveFileDialog so the user can save the file assigned to the Save button.

I want to be able to print the list of items which is in the list box. I found code on here, There are 12 items on the list, when I hit the print button, i get a list of 12 "System.Data.DataRowView" instead of the name of the object on the list. Here is the code I am using.
