How To Populate Listview Control With Contents Of .DAT File
May 19, 2012
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 am trying to populate a row into a listview control and only the first items shows up (the ProductID). the product name, cost, and quantity don't show up.
I guess the control's properties must be set for this. I went and added 4 columns appropriately named, but those column headings don't appear either.
My
'* Add new row to the Order details grid if the currently selected product
'* in the products grid is not already in the Order Details list view
If Not bItemFound Then

I'd like to go through all the items of a ListView control in order to ... well execute some code. I suppose I have to use the "For i=1 to ..." statement , but I am not familiar at all with this control. As I said , I'd like to check all of the items (the elements in the first column) and for each of them that has "Yes" on the third column , I would like to run the rest of the code .

However I need to interact with a program designed in vb from perl (yes I MUST do it this way....)
The control I need to get text from has a class TL80.C1List32.20 I believe this is a listview. I can get a handle to the control just fine.
I have access to the SendMessage function via a wrapper with this prototype:
SendMessage( $hwnd, $msg, $wParam, $lParam );
(A $ denotes a variable in perl)
The listview also has 2 child windows of class: TL80.C1List32.20_SC
which I believe are scrollbars.
I need to retrieve (but not set) the items in this listview via the wrapped SendMessage function.
I can provide any other information you'd like from Winspy++ or can probably dig it up on my own if you let me know what you need.

I am trying to populate a a listview control with items and subitems that a user enters into a group of textboxes on a form. It looks as if some of the code to do this has changed since VB6 and I am confused again. Here is the current code I am using without success:
lvSurgProcedure is the name of my listview control
Private Sub btnAddSurgeProcedure(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddSurgProcedure.Click

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:

using the code below to save and reload the contents (text and images) of a Listview to a single file. The images are about 100x100 pixels.The problem is that if I save the images as JPG (they are already JPG when adding them to the ImageList/Listview), then after saving and reloading the data a dozen times, the images get distorted. When saving/reloading the images as PNG a dozen times, white spots starts to appear on the images. I guess this is because the images are converted over and over again when saving them.Is there a better to way save the contents of the Listview to a single file? I do not want to save the text and images seperately, because then the user has more to tamper with.

This is a follow-up questions to the following post: [URL]
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?

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 am trying to move from the old ADO to the new ADO .NET . However , no matter how many tutorials I read over the internet , I still can't find a way to do something which , as I believe , has to be very simple I tried to mimic the way the graphic control did but I am missing some things ... I noticed that , in the graphic way , the wizard created 4 controls :- a DataGridView control- a DataSet control- a BindingSource control- a TableAdapter controlI recreated all of them and filled their correspondent properties , but yet I can't make it work . I think what I am missing is the connection itself . I looked on the internet and I think a connection can be made and opened like this :
Dim DataBaseConnectionMY As New OleDb.OleDbConnection
DataBaseConnectionMY.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = C:ProsoData.mdb"

I am trying to print the contents of a listview to paper from a toolbar button. In the code below I can get the printer to function and print but cannot get the listview contents to print. I found an old post by Martyr discussing printing listview contents in debugger that was helpful but have not been able to figure out what part of the code to modify for the print sub to recognize the listview contents in the handler. This is what I have so far:
Private Sub PrintToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintToolStripButton.Click
Dim prn As New Printing.PrintDocument
[Code].....
The printer portion of the code that runs on the strip button works without any problems. If I use that button click code above and add something to the PrintHandler Sub like this:
args.Graphics.DrawString("Hello World With A Printer", New Font("Arial", 20, FontStyle.Bold), Brushes.Black, 150, 125)
It prints the "Hello World String" with no problem. The issue is I am not sure what or how to refer to the contents of the listview in the Print Handler Sub or if this is even the correct way to attempt this.

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?
