Possible To Update/refresh Listview On Button Click?

Jun 23, 2012

Imagine you expand onto 'Sofas and armchairs' and click 'fabric sofas', it will redirect to next page on click and it will send data '10661' to the next page. Then the listview will updated with reference '10661'. After that click on another link, maybe leather sofas. The listview will re-update table with new reference '10662'

DoDragDrop List View Item Reordering - User Can Drag Media Tracks From One Listview To Another Listview

Feb 12, 2010

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, _

ListView Rowheight Varies - Using ListView Control, With SmallIcons Style ?

Mar 15, 2012

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?

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?

Form Does Not Refresh?

Jun 12, 2006

I have created a simple VB.NET application with one form and a few modules. When a user clicks on a run button of the form the application starts and goes through differet cycle, while updating the user on status bar, runs for less than four hours.

The application works fine, it gives desired result. However, it is not able to refresh the user form, meaning status bar remains same after some time (it suppose to increment). Even when I take mouse on the form it shows timer symbole instead of default one.

My application commands another device using GPIB. Basically, PC running my application commands the device. If I look the display of device it gives correct information.

How To Refresh Text Box

Apr 30, 2010

I'm making a calculator for a finance company, it keeps track of how much money,bills, and all the totals of everything, and how much your budget is and so on.I have to have it run automatically, by that I mean no buttons at all.  When a user enters a new bill or new payment, I want all the totals to reflect the change, say if I add a new bill, my budget will decrease, and so will how much money I currently have.Here is an example I've made up to show what I've done:In this sample, I have one textbox named TxtTotal, it populates all of the payments you have received, in this case up to 5 payments. I'm kind of confused on how to currectly refresh all the data. Right now I have this timer that will refresh the application every 6sec.  Thats currently my problem, how do I get the this textbox to populate all the data on its own without using a button.

Sub TxtTotal_TextChanged(ByVal

How To Refresh The Checkbox

Mar 2, 2011

I've got a windows form app that displays people and their addresses.A person can have more than one address, one of which is their primary address.The user navigates to the person desired then clicks on a button that displays a form that shows addresses, one at a time,for the person. The user can then navigate thru the addresses.On this addresses form, there is a checkbox to designate if this is the primary address.The user can change this designation by navigating to another address for this person and clicking on the checkbox.There can be only one primary address for a person.

So if a person has two addresses and the first address is primary, and the user wants to make the second address the primary, then they navigate to the second address and click on the primary checkbox.  This is checked for the second address now and should be unchecked for the first.

The programming to change the primary address works just fine. The database is updating properly.  The problem I'm having is refreshing the checkbox for an address that is no longer the primary.It's still in a "checked" state. I have to close the addresses form and reopen in order to get the checkbox refreshed correctly.Is there a way to refresh the checkbox without having to close the form?
