VS 2008 - How To Access Listview Data - Program That Contains A (listview) Control

Sep 22, 2009

I have a vb-2008 program that contains a (listview) control.

View = details
AllowColumnReorder = true

Lets say the table has 3 columns (a,b,c) and 1 row of data.

a b c
1 2 3

I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.

c a b
3 1 2

Statements like:

.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString

Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.

How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?

Getting ListView Items Into Array

Sep 21, 2009

I have a listview with two columns of data in it. I want to capture all the items in the listview into an array. The array will have two dimensions, one for column 1 and the other dimension for column 2. I am a little lost on how to iterate over the listview items. I figure it would be a for each statement. Its also the actual call that passes the found item and sub item to the array I am struggling with.

VS 2008 Getting File Size From An Array Into ListView?

Mar 13, 2010

I'm attempting to get the size of a bunch of files located in a directory with an array. Using a single file, it works great. But as an array, I get an error. This is the code I was using:

VB .NET
Dim filepath() As String = Directory.GetFiles("C:Test", "*", SearchOption.AllDirectories)
Dim lvi As New ListViewItem
Dim fi As New FileInfo(filepath.ToString)

[code]....

It works... kind of. It adds each file to the ListView, when I just want the whole sum. I was hoping I could just use "DirectoryInfo" from the System.IO namespace, but everything I've been reading says I need to loop through the files.

Pulling Item Stored In Array Out Of ListView For Modification

Jun 8, 2010

I have a data entry form, a listview form and a couple of classes. Data is entered in the form, and it is stored in an array. This is then displayed in a listview. I can insert and delete just fine, but I cannot figure out how to modify. This is what needs to happen: With a row selected in the listview, modify is clicked in the menu strip.

Whatever information is in the selected row, it needs to be transferred to the data entry form where changes to it may be made. I have attached what I have so far, and a sample data file is provided in the root directory. I think I need to temporarily store the selected item, put it into the data entry form, delete it, and when submit is clicked have it re-inserted.

Buffer/Array - Safe Application That Contains 3 Threads - Data Acquisition And Decoding - Data Graphing - FFT And Filtering

Aug 26, 2009

I am trying to write a thread safe application that contains 3 threads : -

1 - Data acquisition and decoding
2- Data graphing
3 - FFT and filtering

Thread 1 is collecting bytes from the serial port and converting them int integers (so taking two bytes) after is has captured 64 Bytes and converted into 32 integers, it then needs to pass the array to the graphing thread.

The graphing thread then plots the data and waits for more data.

Thread 3 also waits until thread one has collected 2023 integers and takes these and performs some FFT calculations (which take time).

My question is how do i share the arrays between the three threads without deadlocking the program? as the serial thread will be flying around reasonable fast (1000 bytes per second) so it will synclock onto the shared buffers for most of the time.

Originally i was going to use two synchronised queues, so when thread 1 has collected 32 bytes it queues the data into the graph queue, and once it has collected 2023 it queues the data into the FFT queue.

Then thread 2 and 3 can simple dequeue the data.

However using queues has the overhead of casting the data in and out, and as i know the data type i was planning on using two arrays :-

Dim GraphArray() as ushort
Dim FFTArray() as ushort

Then Thread 1 adds data to each thread, and thread 2 and 3 simple wait until the correct amount of data is available before removing the data. my question is there an array type that allows me to remove x amount of data from an array?

Because i cannot do this easily with the ararys defined as above (GraphArray, FFTArray), as i was planning on making them 1mByte and allowing thread 1 to fill them Knowing they should never overflow and then let thread 2 and 3 remove x amout of bytes at a time unless there is a better way of doing it
