I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

It is really only the last part of the If.. Then statement that I need help with. I was thinking that a loop would accomplish what I am trying but I am still pretty new to VB and do not know the correct code.
I need to create and populate a ListView with 3 strings that come from another function. I also want to be able to select multiple pieces of the data to change their values during runtime (is that possible with ListView?).
I've looked all over online for info on this, but I can't seem to find any.
I've seen somethings on GridView as well. Would that be better for this application?
I've been searching and searching, but I haven't been able to find a halfway-decent way of adding multiple columns of data into a WPF VB.NET ListView. The data I'm adding is not from a datasource. [code]...
I have been reading books and the forums for a rew days now trying to work out how to use any control to carry out the following:Basically, I want to display a selection e.g "Club Name" in a combobox (or similar control) and have the ID of that selection in a separate hidden column e.g. "ClubID". This will allow me to easily reference and store the actual "ClubID" in the required record when I save it back to the database.I can not use the "SelectedIndex" property of the control as the combobox is populated from a 'sorted' stored procedure so the "SelectedIndex" does not match the actual index of the selection.
I have found lots of posts saying use the "ListView" control, but none of them actually show examples of how to bind the control to a data control to acheive what I need.What I am after is a turorial showing ADO code (because I want to hard code this to get a better understanding of how it all works) binding a multi-column control to a SQL database.
I have a procedure that populates a ListView, but it does a lot of work and it takes too much time to display all it's items (about 100-200 items). I want to use a thread to display the items as it's extracting data (real-time).
However, I'd like to embed these files into the application itself and open them from there rather than from looking at the directory.To this end I've added each of the files as a resource but I don't know how to populate the list view with a list of the text files in the my.resources rather than a list of the text files in the directory.
I have searched and searched but have not found code that worked for me. I need to get the data from a mysql db to my listview. I can already connect to the db, i just need the code to get the stuff from it to the listview.
I am trying to figure out how to dynamically populate a listview with data from a file, except I only want specific lines and columns from that file. I have code right now that works to populate the listview from the file, but it writes the whole file and I only want specific lines and columns. Here is the code I currently have to populate the listview when the form loads:
I have a DataGridView which contains a hidden column. On the BindNavigator SaveItem_Click event i need to populate the hidden column cell with the current date. I tried using the DefaultValuesNeeded event but it did not work out.
I've got 1 form that has the user enter 7 fields of data.When they click my "Save" button those values are stored in a .DAT file.On that first form there is a button that brings up a second form with a listview control.I have all the headers set up but can't figure out how to populate the listview control with the contents of the .DAT file.A friend of mine told me I may need a Do while loop but this is my first time doing this and I am so lost. I don't even know where that loop would go and whether or not I need extra variable for it.
I'm a VB beginner. The following image comes from a Mac application that I've developed. This window lists all visible files and their icons for a particular folder.

Below (Example 2) is working code for populating a treeview with directories only down to 1 level. Note just directores are added- No files. I want to add a Listview control beside my treeview and have the Listview populated with the "files" from the selected node in the treeview. This would fire off the NodeMouseClick event of the treeView. I have used Example 1 (NodeMouseClick) before with other code that I have. However, I cannot get the code to work with the Example 2 code below
how to change the Example 1 code to work with Example 2?
Example 1 '************************************************ Private Sub treeView1_NodeMouseClick(ByVal sender As Object, _ ByVal e As TreeNodeMouseClickEventArgs) _
I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
I have a listview and by default it is set to large icons, no problems there. But if giving the user a choice I would liek to see details in the options. I have it set to switch between icons and details but in details mode there is a lot of spacing in the first column. Image attached. The code is below showing how I am loading the listview. Also why so much vertical spacing as well.
Public Sub ListFoldersFiles(ByVal path As String, ByVal lvTemp As ListView, ByVal imgLtemp As ImageList)
i populate 5 listview on form load with some numbers, but i need it to making the first column in all these listviews Bold. When i try to do it, it makes both columns bold.
I'm having problems deleting my listview subitems in the second column. I wonder if it is possible because I always end up deleting the whole row from the database.
I have a listview that has multiple columns. I am wanting to sort these columns when clicking on the column header.I see there is a sort function, but am not having much luck in using it.How can i sort my listview when clicking on the column header?
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 the code below and when I try to populate the listview it populates all of the listview items but only the first subitem. No clue what I've got wrong.[code...]
