here's I've got:

This adds the description to the listbox, no problem. How do I retrieve what's selected?I've gone over many documents on the subject, I kinda got it to work, but it gives me the entire description.... I just need the last value (3) to make it work.
I have 2 listboxes, listbox1 holds File names, listbox2 holds fullpath of the files(listbox2 is hidden just to keep things looking tidy).
What i want to do is (using multiselection) is select files in listbox1 and have listbox2 have the same files(indexes) selected as well.
i am rather new to this but i have tried several ways but listbox2 only selects the first selected file from listbox1.I am using vs2010 visual basic & wpf?
im helping a school run a Spelling Bee aimed at children in year 7. And to make it fair and unbiased i need an application that can choose randomise a word from the list box then transfer the string to the text box.So basically something that can pick a random string from the listbox and show it in the textbox1.text property.
View 6 RepliesI have a listbox with selection mode set to multiExtended. I want to put whatever is selected into an array, but I can't seem to figure out how to do it.

View 4 RepliesWorking with a couple of listboxes to display userid and emailaddress. I am writing an application for viewing SSRS reports instead of using the Report Manager. I am able to select the report and also send an email to users with a web link to SSRS report so that ReportViewer comes up for them to view, export or print the report. Currently I am only able to send to one recipient and I'd like to be able to send to multiple recipients. However I am having difficulty with the multi-select from a listbox. I have set the SelectionMethod to MultiExtended and so I can select multiple items from the listbox. Here is my code -

and I also add a messagebox.show to display my values, in EmailAddressTo variable, it displays "System.Data.DataRowView" so it was not able to capture the email address at all. Then if I debug further I eventually get the error msg - "The specified string is not in the form required for an e-mail address." because of the empty variable. Using SelectedValue, I was able to get at least the first email address but not the second one.
I am a new student of Visual Basic. I am using Vis. Studio 2010. Is there some sample VB code that I can gain access to that shows how to test on multiple selections that were selected within a listbox using the "For each" construct? In this scenario, multiple items have been selected but not 100% of them. I need to know how to test on which ones are selected as I examine each one in the list using the "For each" construct.
View 2 RepliesI have code that works to place two items in listbox into two textboxes when selected (multiple select extended).
Private Sub lstOutput_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstOutput.SelectedIndexChanged
Dim i As Integer = lstOutput.SelectedIndex
[code]....
I need also to be able to modify the data in the textboxes and replace the lines in the listbox. The reverse code doesn't work properly, it only replaces the first selected item. The "lstOutput.Items(i + 1)" appears not to lead to the second selected item.
Dim i As Integer = lstOutput.SelectedIndex
lstOutput.SelectedItem = lstOutput.Items(i + 1)
lstOutput.Items(i) = txtName.Text
lstOutput.Items(i + 1) = txtPhone.Text
I have scoured the web for ways to manipulate the selected index/indices, with no success.

View 1 RepliesI have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String)
Try
TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.
is there a way to retrieve text value from a listbox based on index ?like if i enter index 0 and want to retrieve it's text value from the listbox
View 5 RepliesI want to retrieve the selected items in a listbox, save them to a collection, and then use that collection later. I thought that was simple enough, but when I clear the selected items in the listbox, my collections (items, indices) change. I found this out by stepping through the code.
Basically what I'm wanting to do is move items in the listbox up or down (up in this case), and still keep them selected.

View 4 RepliesIn a small app for demonstrating the use of Regular Expression matching in a text box, I have set it up so I can select one of the matches at a time in the text box to emphasise it. Is it possible to set up a text box so several isolated sections in the text is highlighted so all of the matches are highlighted at the same time. I'm thinking not and could use a picture box to do this but with all the hidden features in vb.net, I wanted to be sure since this would be very handy for my project and would be more useful for large amounts of text.

I'm creating a VB.NET application that includes two radio buttons inside of a groupbox. If the first radio button is selected, a certain tab on a tab form should be enabled. If the second radio button is selected, that tab should be disabled.
Is there a groupbox method that monitors both radio buttons and fires when the selection changes? Or do I need to set up individual methods for each radio button?
Background: Not a developer by trade. I did however, endeavor to learn VB a few years ago and I got reasonably far but without proper motivation for the time, things were difficult to take further. Fast forward half a dozen years and while working with the sales team in my company, I noticed that they were struggling with cataloguing and tracking their calls to clients. They were all trying to use one excel spreadsheet to tabulate all the clients details and calls. Of course, this was a mess. So the idea is to build them a very simple database app that will allow multiple users to add entries to a db and we could pull reports from the data in the end to check performance and such.
Application: The application so far is a very simple access db with windows forms front end. Two tables, one holding �Client� data and the other �call� data. Idea being that we can now track multiple calls per client as opposed to just the next call as was the norm. Client and CallID are the primary keys of the table, with a clientID foreign key in tbCalls . There is one query which I tried to use to do this, which joins calls and clients so that I had everything in one table. Cool. There are four forms, basically frmCaptureClientInfo, frmSearchClients, frmScheduleCalls and frmMakeCalls. Most of these forms are working fine by just dragging the dataset fields onto the form and allowing the IDE to do the coding and then a little more code to validate that the inputs are correctothing fancy just add, delete, update is all this app does.
Issue: The last form is the killer form. Killer form, because it�s caused a huge rise in blood pressure. Anyway it sounds so simple. On the form is a datagrid that is populated with contents of above query (all client and call details), filtered by the parameter that checks if the call is complete or not. Sweet. Below I have dragged in fields from tblCalls. The �callers� need to edit three fields TimeCompleted, CallNotes and a call completed checkbox. What I need is the tblCallBindingNavigator to jump to the record that I have selected in the Datagrid view. Right now they are independent and I can�t join them. If this is at all possible?I have tried using just the query, which has the right behavior except the update command is not generated automatically. Spent Many hours researching updating queries but either was too complex for me to know it was the solution, or was for different products. If there is a way to do this then that would be awesome.I have also tried editing the CallBindingNavigator databindings settings but I am not sure what is going on there, it seems to block out the navigator controls. Here is some more info:
How do you disable additional checkbox selections/deselections without sacrificing the functionality of the ListView? I know you can call: ListView.Enabled = False, but that also disables any scrolling within it.
