View 7 RepliesI have used the command:
For Each Proc as process in process.getprocesses
Combobox1.Items.Add(Proc.MainWindowTitle)

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:

Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

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

View 5 Replieshow to delete a item from the context menu.. i can add a item with this code:
Private Sub Button7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button7.Click
ContextMenuStrip4.Items.Add("delete file")
End Sub
no problem there. and to delete this item, i figured since it is the 4th item in the contextmenu (and i can't type the "delete file" either w/o error) it would delete it by index, with this code:
Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click
ContextMenuStrip4.Items.Remove(3)
End Sub
the (3) is giving me a error "value of type 'interger' cannot be converted to 'system.windows.forms.toolstripmenu'".. i think that means that the context menu does not support indexing.
