Stream Write Row From A Listview?
Jan 8, 2009
I have a small problem with this code. I am adding information to my listview from multiple textboxes. As I add the info I automatically update a text file with the code shown below. The problem I have is When I add my first row the code will not write the data back to the text file, however if I add a second row the code is quite happy to write both rows of data back to the text file. I cannot for the life of me see what is wrong.
'Write tool info to text file
Dim outputstream As StreamWriter = File.CreateText("C:\MFSProFiles\" & CObj(PartNoTextBox.Text) & ".tme")
[Code].....

I have an embedded DLL in my app and I need to write it to the filesystem at runtime. I have this so far:
Dim _assembly As Assembly = Assembly.GetExecutingAssembly()
Dim _rawstream As Stream = _assembly.GetManifestResourceStream("MyFile.dll")
I just need to write _rawstream to a file now.
EDIT: This has to be .NET Framework 2 and CopyTo does not exist

Just starting up on VB 2008 Express (.NET). Trying to write to and read from a file. It runs without errors, but the messagebox only shows the 'OK' button, not the contents of the file as I want. I thought that maybe I have to rewind the file before reading, but AFAICS there is no 'StreamRead.Rewind' or Reset or something.

This app is trying to send messages to a client listening on the port. The client's logs show that their port is being opened and closed, but no data coming in. Is there a bug or something missing in the following code, like perhaps stream.flush or stream.endwrite or a thread.sleep(0) line, that could cause this? The puzzling thing is, WireShark on the client computer does show the message my app is sending coming into the listening port.

in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing

Write binary file in sequence with Listview.I'm loading data from a *. bin file in a listview to modify.Now I want to write listview data in the file.The start offset is 1036.The sequence of each data block is 228 bytes.The number of times to repeat the sequence is 8011.There is more information ... but I put these 3 sample.In the first data block to these lengths are Name Offset 1036 +50 (name space long is 22 bytes)Age Offset 1036 +60
Nationality Offset 1036 + 62
I suppose that before writing the data in the file would have to convert the data item and subitems in hex or byte.

I have managed to get it to write a string to a textfile if the listviews checkbox is checked but i can not get it to write a particular string if it is unchecked.
'LOOP CHECKED ITEMS
For Each lstItem As ListViewItem In Me.ListView1.CheckedItems
Next
How do i Iterate an unchecked item as the library doesn't have .UnCheckItems?
If its checked i need to add "true" to the string and if its unchecked i need to add "false" to a string that gets written to a textfile.

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

I'm using ListView control, with SmallIcons style in VB.NET. Icons are loaded fine, but when I start to scroll ListView down or up from scrollbar (clicking from arrows), rowheight drops to about half from normal in next 20-30 rows below/above upper/bottom row (depends from the scrolling position). After 1-2 seconds, ListView is "refreshed" and scrolling continues normally. When focus in on the ListView and I'm moving up/down with arrow keys or PageUp/PageDown, everything is normal. Any suggestions, what is happening? SmallIcons size is 16 * 16. Is it compulsory to set "Blank icon" with SmallIcon size to all rows, when adding them or what? Wasn't like that in VB6, how is it in VB.NET?

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?
