VB 2010 List Box Multi Select Loop
Jan 24, 2012
i have having a annoying problem to do with loops.
[Code]...
When the user selects a few rows from my list box i want to run code on them selected items which i can do fine, but when the user only selects one of items and hits the button. it goes throught the loop first and gets the picture and all is fine its when it comes back to this function after there are no more items to perform tasks on. it increments index again and then falls over because its out of bounds of the array. i want it to stop after one loop but i also want it to be able to have the multiselect option still so the user has a choice.

can someone give me some pointers.I tried me.lstItemSizes.SetSelected(i,true) but this only works for a single item.

I have a form on which I want the user to be able to select a name from a list. The list needs to be populated from an table in my dataset. I'd like the user to begin typing and have an autocomplete append select type feature let them zero in on the person they want as they type. My question is, what type of control would work best for this?

I have a listbox with two columns. Each listbox item contains a horizontal stacked panel which in turn contains textblocks.
The listbox is empty, with each listbox item being added by the end-user through a couple of textboxes placed elsewhere. The first column accepts strings, and the second column accepts only percentages.
(I have attached a relevant portion of the event sub where a user is adding new rows.)
Private Sub btnAddItem_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles btnAddSplit.Click
'...
Dim ListBoxItemName As New TextBlock
[Code]....
I would like to be able to check every time the above event is fired that the column of percentages does not exceed 100%. I have a couple of labels below the listbox itself where I would like to show the running total and the remainder.
My questions are:
1) How can I loop through the second column of percentages to show the running total and remainder?
2) Is there something more suitable than a ListBox that could make this easier?

Can a listview multiselect in the same way as a listbox can, when it is set to electionMode = multiSimple?for instance when the listbox is set to selectionMode = multiSimpleyou can just select any number of items in the listbut...with a listview you can only multi-select when you hold down Ctrl. As soon as you lift the Ctrl key and click on an item it de-selects everything and only selects the last one you selected

i have been given the task of making a small program in vb.net to have two list boxes. The first list box contains the data and the second one is blank, when you select the one bit of data from the first list box it can be draged and droped into the other list box. my task is to make it so you can select multiple bits of data from the first list box and all that is selected is draged over to the second one when you drag and drop it.

I have a list box that is bound to a table in a database. It produces a list of companies. The user will then come along and select multiple companies that they want to view information about, and then they hit a select button which I'll display the company information (e.g company name, company site, address e.t.c) in a gridview underneath. However the issue that I am having is that it only displays ONE of the multiple companies selected and its always the top one. How I get all the companies to be displayed in the gridview?
I am programming in vb.net
<asp:ListBox ID="ListBox1" runat="server"
DataSourceID="SqlDataSource11" DataTextField="compName"
DataValueField="compDataID" SelectionMode="Multiple" AutoPostBack="True"></asp:ListBox>
<asp:SqlDataSource ID="SqlDataSource11" runat="server"
ConnectionString="<%$ ConnectionStrings:IWSRiskAssessmentConnectionString %>"

I made a program (As usual) that plays media files using the ax.interlop.wmp.dll (windows media player). I also made a listview on the form that has gridlines. i have a problem with my mutiselect feature though. it just adds the same filename for every file, but in the amount files (Ex: if there is 8 files, it adds the name of the first one 8 times) i just want it to add every single filename to different rows, here is the current code that i have:
Sub openFile()
With OpenFileDialog1
.DefaultExt = "Mp3"

I've spent FAR too long trying to troubleshoot this simple operation.I want the user to select multiple files in an OpenFileDialog (called OpenFileDialog1), click OK, and then have the filenames display in a listbox (called ListBox1). When I run, the openFile dialog allows the user to select mutliple files. However, on clicking OK, the dialog repons allowing the user to select only a SINGLE file. Then, it throws an "outside of array" exception.

I have a listbox populated with dates in the format of dd/mm/yyyy e.g. 12/03/1983, 06/07/1987 etc.. Could someone please post the code that I could use so that I could search the listbox to multi-select the dates that fall within a specific month (not year or day). So for example I might want to highlight all the dates that contain the month **/10/** (october). I'm really struggling with this.

Ok lets say you have a listview well call it "lv". There are items A, B, C and D. If i select A, C and D (holding ctrl) and hit a button it enters A, C, and D in a text box like below
"A(space)C(space)D(space)"
note: (space) is a space
how would i go about doing this? Below is the button that you would hit to send the selected items text into the textbox. (doesnt work)ERROR i keep getting: InvalidArgument=Value of '3' is not valid for 'index'. Parameter name: index

I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?
