VS 2008 ListView Control - Adding Items From SQL Database
Nov 16, 2009
I am very new to Visual Basic, and I need to add items from my database to the ListView control. I have a table in the database called tblChannels that I would like to draw the information from and populate the ListView control in VB, in the form of a column. I currently am unsure about how to go about doing this. Previously I have created combo boxes that draw the information from the database, but trying this method for the ListView does not work how I want it to.

I need to be able to add items to a ListView Control and to additionally add a label as well. I have included an image to serve as a reference. This is for an application I am building for a handheld device.

The following code will display items in the listview control when For Each strElementToSearch As String In fruitArray loops once using the string strTheses1 however when it loops again using the string strTR1 it will replace the items from the first loop. In another words I want to keep adding items to the ListView control. [Code]

I have a listvew that is setup like:
[COLUMNHEADER1] [COLUMNHEADER2] [COLUMNHEADER3]
[CHECKBOX] Graham
[CHECKBOX] Greg
[CHECKBOX] David
What i was trying to do is put text in [COLUMNHEADER3] besides each of the names, so if "Graham's" details exist then put "PASSED" beside the name "Graham" and "FAILED" if it's failed, i'm not sure how to access the 3rd columns details to put that in is it:
formname.listview1.subitems("")

So, i'd like to ask you! How can i add new listview items to a ListViewItemCollection (or something better), and than add the items in the collection to a ListView. The point of all this is to add listviewitems from a background worker.

I've got this code which basically loops through a set of folders and subfolders and finds specific file types. And then lists these in a listview. Now, it's intended to list exe and msi files. And I've made it so that these icons can be doubleclicked after they have been listed. I do this by adding the path to the file in it's tag property.
But, my superiors want a checkbox next to each item. So that they can check each item they want installed. And then have a button which runs the path in each tag property one at a time. It's basically the part where I fill the listview with the checkbox, filename of the exe or msi file, tag and the icon that I'm wondering about.
This is the existing code. This includes just a Tile view of the listview. Public Sub getDirectories(ByVal strFilepath As String, ByVal strFileExtension As String, ByVal objControl As Object)
'Load first files from the root folder. Then loop each subfolder
Dim di As New DirectoryInfo(strFilepath)
Dim aryFi As IO.FileInfo() = di.GetFiles(strFileExtension, SearchOption.AllDirectories)
[Code]...
But there should be a way of combining these two right? I'm not sure how I can add a checkbox in the first column of the listview? I've already set the Checkbox property of the listview to True. But I could use some pointers here if anyone's got any. :)

For some reason, the following code is causing me some issues. This code pulls lockout status data from AD and contains the data within a datatable. An event is raised from the threaded procedure to add the data to a listview control. For some reason one row of data gets added to the listview control and when you run the procedure gain, 2 rows of the same data gets added, and then 3 rows, etc.
This code calls the procedure "CallGetUserLockout"
GetLockoutStatusToolStripMenuItem.DropDownItems.Add("For Current User - " & User, Nothing, AddressOf CallGetUserLockout)

I have a tab control, that the user can add/remove tabs as they please. It is an inventory manager, and the tabs are the departments. Everytime a user adds a department, a new listview is cloned and added to the page. Upon form load, i need it to go through the tab pages, and query the database for items matching the department their in. In other words, if the Department column in the inventory database, matches the Tab Pages text, add it to the listview inside that particular page. I've tried several things, but they all end up buggy. Either it adds them all to the first listview, or it skips every other page, or worse - doesn't add anything at all. Here is the code I have, could anyone help me figure out how to:
Cycle through the pages, if any of the DB's rows Department column matches the tab page text, add it to the listview inside that tab page, then move to the next tab page, and cycle through the DB again. Here is my code, a decent start I believe.
Sub FillList()
Dim incs As Integer
Dim inc As Integer
Dim lst As ListView

I have created a user control that mimics what a label does. I realize I could have inherited the label control, but I am working on understanding the process. I wish to add items to the control. normally (in the code of my project) would do:
Form1.Label1.Controls.Add(mylabel)
After creating mylabel in the code of course.

I want to set a color on items and subitems being displayed within the listview control in a detailed view.Using the forecolor property setting would change the color of all the contents in the listview control. All I want is to display different colors on each column of the listview control. If I have four colums on the listview, it should display the contents on each column in a different color. I tried to do it on my own but it was unsuccessful. I'm looking for the exact code to set the color successfully. Currently, the code below is what I have to display the data on the listview. What line of code should I add on the code below to set different colors on items and subitems of the listview?

Most of the project I do, I use the datagridview to display the data from the database. What is the different between the datagridview and listview? If I want to display the data from the database, should I use the datagridview or the listview?

I have a ListView with the columns 'Name', 'Expected', 'Total', and I want to add another column saying 'Recount' at the end. The 'Recount' column will ideally have a checkbox only if the 'Expected' value is larger than the 'Total' value.
So far I have got the ListView with columns and can add a check box on the left hand side, but that check box is not under a column heading (though I can probably put another column with no values in there to work around that) and it is on all of the records.
