Ime1 = ListView1.SelectedItems(0).Text
ListView2.Items.Add(Ime1)
If MkCal1 < 0 Then
ListView2.Items(0).SubItems.Add("Nepoznato")
Else
[Code]...
The problem is when I click the next time to button, listview2 add only first rows from listview1
Basically what I want is when a person clicks on an Item that ends in "Mp3" in Listview1 to then Create that same File on Listview2 So far It will create the File, not show its name. and it gives the directory, but not all the way.
Heres the Code for Moving the file to listview2.
If ListView1.FocusedItem.Name.EndsWith(".mp3") Then
ListView2.Items.Add(ListView1.FocusedItem.Name.ToString, 4)
'Add SubItem Information.
Dim li As New ListViewItem
li.ImageIndex = 4

I wont get anything to pop out on Listview2, even if I click anything on listview1. I have to group (left click and hold, and go over multiple items.) And if I am lucky I will get some stuff on Listview2. I got 1 item to move to listview2 but it has no name (it does not appear). Now if we move the scroll bar to the right, we will see another error, (next picture). The Directory Does not end with the Music's Name.mp3. And It does not even end in the same directory as the textbox on the bottom right corner?
I have program that scan the file in a folder, and when user click button its will Folder Browser dialog 1 will appear, and when user hit ok, Folder Browser dialog 2 will appear after that the program will show the file in selected path of folder browser dialog 1 in listview 1 and ile in selected path of folder browser dialog 2 in listview 2, I already handle this but I want program to compare items in listview1 with listview2 and show missing item in listbox1. for example: I have the listview1 contains 2 items that is "Snow" And "Storm" and listview2 contain 1 item that is Snow, I want when user hit button, the listbox1 will add the item that listview2 not have in listview1, so listbox add the Storm...
View 2 RepliesTrying to build a file compare utility to compare two files and visually show the differences in the rows. I have a form with two panels and a listview in each one and a vertical scrollbar in between that will control both listviews.First listview1 inside panel1 will load during form load depending on what is selected on my mainform grid. 2nd Listview2 inside panel2 will load from btn1, this only works once.The compare is done with btn2 and it works okay also.The problem I have is after I have both files loaded up in the form, and I do the compare, everythign works fine but I can't figure out why I can't seem to re-use btn1 to open up another file.It seems to go through during debugging but the listview2 will be blank. Only does this after it was first used.[code]
View 2 RepliesI have an ArgumentException was unhandled message: Cannot add or insert the item '1' in more than one place. You must first remove it from its current location or close it. Parameter name item. Note: Have 2 listboxes 4 textboxes double click listbox2 and it fills in the four texboxes (now it needs to put it back into listbox2 in the same place it came from but crashes. I marked the area and underlined where the error message was coming up. So double click a selection in listview2 (fills 4 textboxes) then double click textbox2 (should return text data back to listview2 in same spot) but crashes. See code below.

i was trying to paint a row of a listbox item but ppl said that listview item is much better than a listbox and has the ability to paint items, what i couldnt get it to work however is to add an arraylist to the listview what ive tried was the following:
datasplit.AddRange(progressload.Split(New Char() {"'"c}))
Dim items As New List(Of ListViewItem)
items.AddRange(datasplit.ToArray)
[code]....
Is there any easy way to add an arraylist to listview?i forget, is there a possibility to make listview order items like a listbox? i dont want from left to right then down then left to right then down... etc I want them to be top down and keep like that no matter the dimensions of the listview.

This is my thread, everything works fine. But i have a big list of proxy severs. ListView2 contains the proxy servers and ListView3 contains the ports. When a server response with nothing the proxy + port is removed from the list. But i want that if a proxy is valid that it's moved to LisView6 & 7.Now i've marked the placed where the problem occurs.

I'm new in VB.net but I'm trying to make application (planning-game). The game is about showing students the planning 'complexity' of a operation room in a hospital. I created a listbox which randomly shows 5 operations. But now I would like a function which makes it possible to add a selected operation to a timetable. The timetable has blocks of 30 mins (example 08:00 - 08:30, 08:30 - 09:00 etc..). This because 1 type operation takes 1 hours and 1 takes 1:30 hours. Now I have given the operations a value by using a label. [code]
View 1 RepliesI have an idea about improving the assigning operations of VB.NET (maybe other .NET languages too.) It is similar with "With ... End With" block:

So we don't type "Some Text" every time. Do you think does this idea work? Maybe in the future we can see something like that?
I have an application in which I am running a separate thread.
Dim thread As New System.Threading.Thread(AddressOf Main)
thread.Start()
However, the thread makes reference to an textbox named Output, and it generates this error upon execution:
System.InvalidOperationException was unhandled
Message="Cross-thread operation not valid: Control 'Output' accessed from a thread other than the thread it was created on."
Source="System.Windows.Forms"
(message shortened for space)
How can I make the operations run on another thread, but still use the Output object? I cannot call a subroutine to do that for me, as it generates the exact same error.
The method called is AppendText, by the way.
I have 2 child nodes under a particular node. I want to do operations on the second child node. The code goes like:

View 1 RepliesI want to create a dll in VB.NET. The functionality of the dll is that it should include all the xml operations. Any application that uses this dll will just pass the node that has to be selected. The dll will accept the node name and search for the node in the xml file and return the details of the node. For example:if the xml file is like
<Node1>
<Node2>
<Node21 Attribute1 = "Value1" Attribute2 = "Value2" />
<Node22 Attribute1 = "Value11" Attribute2 = "Value22" />
[code]....
If the application which uses the dll calls a function named readNode(Node3) which is defined in the dll, then the dll should be able to retrieve all the details of Node3 including subnodes and theire attribute values and return it to the calling application. All the XML operations are to be done in the dll. The calling application will just call the method in the dll by passing the node name and it should be able to get all the node or attribute values.

In my projects (WPF) I use System.Windows.MessageBox to show the user a confirmation dialog for operations that are critical, such as a delete-operation.
My problem is that if I specify as button value MessageBoxButton.YesNo, the user cannot use the escape-key to cancel the operation. IMO this is one of the most annoying things, a program can do, showing a dialog without the possibility to cancel/close the dialog through the escape-key.
Other possibilities are MessageBoxButton.YesNoCancel, but IMO this is confusing because it shows three buttons for only two operations . Or one can use MessageBox.OKCancel, but this is IMO not clear enough. In my dialogs I want to ask the user if her really wants to execute the operation. And for this, a simple ok is not appropriate. A yes (I want) is much better than an ok (go on).
How do you handle this? Is it a non-topic or do you think as I do and have an own MessageBox-implementation or do you know a possibility to extend the System.Windows.MessageBox-class?
On compiling a visual basic assembly, int32 variables are cast as int64 for calls to adodb methods that require int32. This results in a method not found exceptions at run time. The unnecessary cast operation can be seen when using reflector to inspect the site of the method call and is not present in the source code.To further muddy the waters when the code is compiled on my 64bit windows 7 machine all is well, but on a 64bit windows 2008 r2 the unnecessary cast is added.
