I have a listbox with SelectionMode = MultiExtended. I am trying to capture all the selected values to end up with 1 variable that includes all the selections in the listbox.I'm getting error "Public member 'Selected' on type 'String' not found." at the start of my If statement
Code:
For iLoop = 0 To Me.lstVDN.Items.Count - 1
If Me.lstVDN.Items(iLoop).Selected Then
VDN = VDN & Mid(Me.lstVDN.Items(iLoop).Value, 1, 5) & "','"
End If
Next
Clipboard.SetText(ListBox1.SelectedItem.ToString)to copy the selected item, is there a way loop the listbox and copy the entire text? im assuming i would have to loop the listbox to a textbox first them jus
View 5 RepliesAt the moment I have a listbox and two buttons. The first button will add files from a directory to the listbox, whilst my second button processes a single txt file inside a folder to remove certain words, then save the processed document as a copy.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
' Replace common words and all symbols.
Dim wordsToReplace() As String = {" cat ", " hat ", " that ", ", ", ". "}

What I am trying to do now, is rather than process documents in a static folder, I want to process the documents that are inside my listbox, and save the new copies back to the list box (repopulate the list box with the processed txt files, I hope that makes sense). What I think I need to do is loop through the listbox and take the file path for each item, process it, then feed these back into my listbox.
I have a form with a listbox. I'm adding items to the listbox through a file that I saved. When I open the file, I want each line/string in the file to go in as a separate item in the listbox. I've gotten it to work so far but only with 1 string. I need to loop the part where the file is being read to be able to add all the strings that are within the file to the listbox. How do I do this? So far, this is the code I have:

i have 2 list boxes.. Qty and Cost both of these are populated from a sql database. The code is suppose to read through the listboxes and multiple the Cost by the Qty and then replace the Cost with the new result. The Cost listbox is populated with the cost of one item. The reason i am not doing this calculation in the sql query is because the sql query is very complicated filter out a bunch of stuff to show just the qty of the item...

I need to find a method of looping through a listbox and retrieving the index number and values - quite straightforward in asp, but turning out to be something of a nightmare in winforms!Here is the scenario - The user can add values in a textbox, that are in turn added to a DataTable that gives it a unique ID and a row number, this is then bound to the listbox. The user can then move the items up or down the list by adjusting the row number in the datatable and rebinding to the listbox..
The problem that I am hitting is when the user needs to delete an item -the first part is easy - delete from the DataTable and rebind to the listbox. The bit where I hit the proverbial brick wall is needing to loop through the listbox rows and getting both the index number and the ValueMember - that way I can change the row numbers in the DataTable based on the index number against the ID number.
If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False

1 when my listbox returns resaults it only brings back 10 how do I set it to return lets say 500

This is my code

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

I'm trying to write a program right now for my computer science class for a program where you insert text into a text box, (the text being a password), and then click a submit button. The goal of the assignment is to have a program that looks at the user given password and see if it matches the const password (or one of the three const passwords in my case). If it doesn't, it is supposed to loop back so you can re-input the password. Also, If you enter the correct password, the loop ends and you are to get a msgbox (or, in my case three different ones), and then the application closes. We are to write the code so that if the password is wrong "x" (insert 3 as the number I have chosen), a MsgBox will pop up with a message saying
something along the lines of "you have gotten the password wrong to many times.", and then the application is supposed to close. I don't think I could rant on much more, I've done a good (or in my eyes terrible) job of summarizing the assignment.
[Code]...
My problem (aside from, I don't know, a problem with my code itself) is that when It reaches the loop, it goes through all the code again, but I'm unable to change the user given password, and so it just pops up the three failed password entry MsgBoxes (the code for which is temporarily removed), then the failed to many times MsgBox, OR one of the successful message boxes. What I'm wondering is if anyone can help me fix my code so that it functions as desired.
I need a loop to run in the background while my app. is running. The loop has to constantly check for the value of a var and return a value based on the values of the var.

View 10 RepliesOn a form I have a series of 20 checkboxes (cbS1 through cbS20). With that I have an integer named 'Count'
What I need to do: When the forms loads it will get a value for Count. I need all the checkboxes that are greater than this value to be checked.
So if count = 7 then cbS8 through cbS20 will be checked.

So basically the data contains events, runners and odds. I'm looping through and assigning the variables to the relevant object propeties, alls fine.
The problem comes when I'm checking the next runner id (or event id) to see if it's changed so that I know to create a new object. Well in checking that the id has changed I've already moved one record too far so every time I'm changing to a new id I'm losing one record.

First thing:
How do you loop through an xml that has repeating node block (<STRUS name="1000A") and extract the following node? For example you want to extract the IdentificationCode in the node that has <SVALU name="ZRT" and is from pos="9".So, the following example has the IdentificationCodes (TGJ23, PGA12, TPX12)
