Repopulate ListView In Program?
Jan 13, 2009
I have an Excel file I need to leave undisturbed. I can loop through it and populate a ListView with columns during form load. After that I want to repopulate the ListView, changing column headers and presenting the same data in a different order or with some columns absent. If I created my Excel application As Object when loading the form it is obviously no longer available from a new button as the button is Private. What is the convention for doing this? Does ADO.NET work with Excel? I want to keep the data source invisible (.visible = False) yet manipulate it for the ListView. I could create a text fiile from the Excel and loop through that in each button code. That seems a poor way to do it. There will be no input from the user, just reading from 22 columns displaying only 3 or 4 of them at a time in ListView.

I have a form that among other things displays a list of customer names in a combo box. Should the person that launched that form not see the customer in that combo box they can launch another form that will allow them to add the missing customer. The 2nd form adds the customer name to the customer table and the customer information to the customer information table - the 2 tables are related by the CustomerID.I have no problem saving the record to each table but in the process of saving the customer name to the customer table, I would like to refresh the combo box on the 1st form so the newly added customer is displayed in the combo box it was previously not found in.Each time the new customer is added I would like to update the combobox with the new customers name so the user of that form can use it to complete the task it was designed for. I have tried "frm.combobox.refresh", "My. frm. combobox.refresh", changing focus to the first form - none of which worked.

I currently have a page that is populated using a filter, which passes the parameters of the filter via URL.
I'd like to catch those parameters and give the user the opportunity to return to the page with the same filter applied to their view. Essentially, it's a back button. AKA: pass the parameters back into the URL so it repopulates the page.

I just wanted to confirm couple of things.
I) Code snippet:
cmb1.Datasource= dt;
cmb1.Valuemember = "value";
Does the control rendering happens 2 time for the control, 1 more time extra because of the value member getting changed after data source assigned. Is this so?
II) How can I trace these re-populations in C#? I just wanted to debug and see and confirm?

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?

So here is where I'm at, I've built a program to organize my programs. I've got the tabs and all of that, everything on it works fine except I have one issue now. Every time I close the program then open it again, any files I've added into it have disappeared so I would have to constantly run this program and if i restart my computer I would have to re-insert the programs into it. I'll include what I have so far in the way of the coding. But I was wondering, how do I get it to remember what I've put into those ListView boxes?
Public Class Form1
' Private Shortcuts As Dictionary(Of String, String)
Dim c As Integer = 0

I'm trying trying to add a feature to a program i'm working on that puts the start up programs on a system into a listview.
The start up items are stored in the following registry location: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun
What I would like to do is read the Program Name value under the Name Column in the registry and the Data Value under the Data value and put these values into the listview in two seperate columns like Msconfig utility see the screen shot.
I'm familiar with working with the registry in .NET, but I can't seem to get this to work. I believe I would need to loop through each registyvaluename under this key and get the name and value.

I have written a program that queries an sql database displays it in a detailed listview, no problems so far. The only problem I am running in to is when I got to print the listview. When I do a regular printdocument.print() It prints out the listview exactly how I have it set up to do so. Which is a title , then column headers, next comes the listview, and then a total of some the columns. When I do a printpreview everything looks great. When I click the print button within the printpreviewdialog only the Title, Column headers, and the totals print. [code]

I want to change the color of the group header text in listview which separates all the items into various groups, there is no such option to do that directly because no such property exists.
As far as i can think of it can be achieved via overriding the paint event but i have not done any overriding of paint events on windows controls so far.

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?

Do I really have to go through all this just to find out what item has been selected in a ListView?

Isn't there something fundamental like this? Is absolutely everything in VB.NET buried beneath a colossal heap of bureaucracy?
