Pulling Item Stored In Array Out Of ListView For Modification
Jun 8, 2010I 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.

Getting The String Value Of A ListView Item
Jul 31, 2009I'm writing an application to help manage an employee database. It displays the current entries in a ListView control using the SELECT FROM sql string and allows entry into the database using the INSERT INTO sql string. What I want to do is have the user select an item from the listview and be able to delete it from the database. How I'm trying to go about it is by detecting when the user presses 'Delete'. When they do, the program gets the string value of the item, hands it off to a variable, and the variable goes into a DELETE FROM sql string and deletes the row in the database.
I have multiselect disabled in the control so only 1 selection is possible at a time. I don't know how to detect the Delete key or how to get the string value of a listview item into a variable. If I know how to do these two things, I can work out the rest of the application. I'm still kinda new at this kind of stuff, so any responses will have to be dumbed down a little.

Set Listview Item's Background Color From A String?
Dec 21, 2009I'm kind of stuck on this one, and i know it's going to be something simple, but I just can't come up with the solution. I want to be able to assign a background color for each item in a listview with a predefined string or other variable type, so when item's are added to the listview and they contain a specific string, the background color for that item will be changed to the predefined color which is stored in a string (or other variable). When I attempt to change the background color of the listview item using a string ie. "Blue" I get an error.[code]....

Edit Item Or Subitem Values Of A Selected Listview Item?
May 19, 2009Ok, 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.

DoDragDrop List View Item Reordering - User Can Drag Media Tracks From One Listview To Another Listview
Feb 12, 2010I 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, _

View 7 RepliesAdd An Item To A Listview?
Jul 30, 2009I've currently picked up a small project and they one who assigned me to it wants me to upgrade the app using .NET.Is there any way I could add an item to a listview when I'm not on the form containing it? In VB6, something like this would work.
'Code on Form2
Form1.ListView.ListItems.Add "Item Name"
but in VB .NET, the code below doesn't add anything to the listview. It doesn't return any errors too.
Form1.ListView.Items.Add "Item Name"
And another thing, why is it that when I close the Login form to launch the Main form, the Main form closes automatically? The code in sub main is
' shared sub main
Application.Run(New frmLogin())
Then when correct credentials are given to the form, I'll do this.
'login form
Dim frmMain as frmMain = new frmMain
frmMain.Show()
Me.Close()
I assume things are done a lot differently than VB6.

Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?
