how to add a string item to a text box, returned from another form that has a list box?
I have two forms. on the first form I have a button which calls another form that has a List Box.
When I select the value from the list box and click on the apply button then the value should be
passed to the first form that will also have a text box. The text box should contain the value of
list box.
there's a list-box with items, and say you want to modify an item in the middle of the list. You select that item and click "Modify" button and a new form appears with the previously selected item data from first form ready to be modified in a text-box. After modifying and clicking Ok the second form suppose to return that modified string to the first form and insert the modified string into the same spot instead of the originally selected item, so it looks like it was edited to the user.

I need to get a string from an items collection in a list box on one form to a list box on another form in VB 2008. Here is the code (I've tried a couple ways in the code to get the values over).

I have a radio button control on a web form. The members of my ListItem collection are
assigned the following.
Text No
Value 0
Text Yes
Value 1
So what I need to do, is to readd a varchar value from my database and if the column value returned equals 'Yes' then I need to select the radio button that has the assigned value of 1. Otherwise if the value read from the database is 'No', then I need to select the radio button assigned a value of 0
So how can I set the value for my radio button? I experimented and could not figure it out. The 'Yes' or 'No' value is stored in my database in the field ds.Tables("employee").Rows(0).Item("answer")
So I tried something like this which is not correct:
RadioButtonList1.Items.FindByValue(ds.Tables("employee").Rows(0).Item("answer") = "Yes").Equals(True)
Im still doing some amatuer programming, but now in .net and Ive come here with a question that I cant seem to find an answer to... Basically, Ive got a program im writing to interface into my companies AD and return some values, which then trigger other events etc..
The problem Ive run into is trying to find and easy way to compare the returned value when against a list of possible combinations (16 possibilities to be exact), and if its one of them then all good continue on but if not then I need to throw an error and exit sub.[code]...
I have a problem with a For Each Loop that doesn't make any sense. The For Each Loop returns values from a list which are Memory Ranges for a given device. When I check the count in the list it returns 3. The For Each only returns 1.

Private Sub DisplayDeviceResources(ByRef lvwResources As ListView, ByRef intClassIndex As Integer, ByRef intDeviceIndex As Integer)

I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

I am currently writing unit tests for an application near completion (before management looks at it and turns it inside out). I am testing the business layer and a method is set to return a datatable of all "GroupID"s, which are simply an integer to represent the group that a user belongs to.
I'm assuming the best way to assert on this unit test would be to assert that the correct groupIDs are being returned from a controlled test database. However, I'm not sure how to assert on a datatable. Is the only (and best) possible way to accomplish this to simply loop through the datatable until it's empty and add each value to an array of integers? How would one go about asserting on this test?
I was wondering how to add the text from a text file to a List(Of String), one line per item (in the list).

It seems simple enough, but apparently I cant figure it out. Theres more to my actual problem, but once I figure out this concept then I can do the rest. I want to search a list for a given string, and if it matches, then print it out. If it doesnt match, then it moves to the next item in the list. If if doesnt find any matches, it says "no matches found".

I don't think the web server is trying to encode anything as there are no + symbols within the url string and I have just glanced over the two to compair they are the same.This returns a blank string whereas when I use the sections commented out in the first loop i get a really weired string back and when I use their simpleXor function it just returns complete nonsense.
My program creates a array of numbers as entered by a user and then finally adds them up. The form should be able to display the numbers typed in by the user. I know how to put one of these numbers into separate labels and could display each number that way but I wanted to know if there is a simple way to display the string that is created as a list in perhaps a read only text box or similar?

I'm trying to solve a problem regarding types of list. First of all I have a stored procedure in my DB which does a select of a single column and I try to proceed it in my app in VB. By making a method function I declared a DataTable that loads through the SqlCommand(with the CloseConnection behavior). After that I publicly declared a List(Of String) which needs to be populated with the rows/items from the stored procedure that is on the way. Below is my snippet of the code:
Dim dt As New DataTable()
Try
If conn.State = ConnectionState.Open Then
[Code]....
It's LPrefix = collection.Cast(Of String)() where I get an exception error telling me that I can't really convert it. The old fashion way is to iterate with for/for each loop but that's not what I want for best use of performance especially if the list will have thousands of rows from a single column. So basically, I want to insert those items from that DataTable to the List(Of String) without For/For Each loop.

The intention is to convert an IList of custom objects to a string equivalent comprising each element in the Ilist. Unfortunately I can't seem to find a way to get the underlying data of the custom object, and of course as in the above example, using object simply gives me a string of types definitions, rather than access to the underlying data.
