I am trying to figure out how to dynamically populate a listview with data from a file, except I only want specific lines and columns from that file. I have code right now that works to populate the listview from the file, but it writes the whole file and I only want specific lines and columns. Here is the code I currently have to populate the listview when the form loads:

I've got 1 form that has the user enter 7 fields of data.When they click my "Save" button those values are stored in a .DAT file.On that first form there is a button that brings up a second form with a listview control.I have all the headers set up but can't figure out how to populate the listview control with the contents of the .DAT file.A friend of mine told me I may need a Do while loop but this is my first time doing this and I am so lost. I don't even know where that loop would go and whether or not I need extra variable for it.

Below (Example 2) is working code for populating a treeview with directories only down to 1 level. Note just directores are added- No files. I want to add a Listview control beside my treeview and have the Listview populated with the "files" from the selected node in the treeview. This would fire off the NodeMouseClick event of the treeView. I have used Example 1 (NodeMouseClick) before with other code that I have. However, I cannot get the code to work with the Example 2 code below
how to change the Example 1 code to work with Example 2?

I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

I have a windows form in VB.NET. In that I create two Comboboxes dynamically during runtime. Lets name them CB_A and CB_B. Now when these are created, CB_A is populated by calling the handler which is created while creating the control.I want to populate CB_B which will depend on the value selected in CB_A. e.g. The first value in CB_A will populate one set of values in CB_B while the second will populate another set and so on...The approach which I tried was get the name of the CB_A and then deduce the name of CB_B, but it does not recognise as it says it cannot change from string to objec(combobox).

View 10 RepliesI am creating an electronic display board using Visual Studio 2005, this will be an application using VB and not web based.What I am trying to do is use labels dynamicly and populate them from a dataset, Now there is a lot of labels on this board and to be honest the perfect solution would be to use a Data Grid View, unfortuantly I have to fit the information into a Custom Graphic that was created, hence the reason for labels.So obliviously I dont want to have to name each label and specify its information, for example:
Code:
Label1.text = MyDataSet.Tables(0).Rows(0).Item(0)
Label2.text = MyDataSet.Tables(0).Rows(1).Item(0)
Label3.text = MyDataSet.Tables(0).Rows(2).Item(0)
So I thought about something as follows but not sure how to get it work.Say I new I had 100 Labels Label1 to Label100.
Code:
Dim i as Integer
For i = 1 to 100

I have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.

I have a database in ms access. I am trying to use a listview to populate this database. I have comboboxes and textboxes that populate the listview. I have tried to just make sure that my database will populate with the combo boxes before I try to code it to populate from the listview.

Syntax error in INSERT INTO statement.
The error is occurring in the da.update(ds, "TrapDatabase") line.

I want to populate a listview with items from datagrid view. I've been searching for solutions but it seems that all the scenarios I found were about populating listview with items from tables in database, not from another listview or datagrid view.
I'm trying this code:
For count As Integer = 0 To (DataGridView1.Rows.Count() - 1)
Dim row As DataRow = DataGridView1.Rows(count)
Dim item As ListViewItem = New ListViewItem(row(fieldfirstcol).ToString())
item.SubItems.Add(row(fieldsecondcol.ToString()))
ListView1.Items.Add(item)
But it doesn't work; it says DataGridViewRow cannot be converted to DataRow.
Let's say I have 50 cars and I created 6 attributes for each of the 50 cars (therefore 300 total variables and values for those 300 variables). These attributes are created and valued based upon the following structure:
Car1Name = "Dark Red Car"
Car1Color = "Dark Red"
Car1DoorCount = 4
Car1Cost = 10000
Car1Appeal = 10
Car1BoughtStatus = False
Car2Name = "Bright Red Car"
Car2Color = "Bright Red"
Car2DoorCount = 4
Car2Cost = 11000
Car2Appeal = 8
Car2BoughtStatus = True
and 48 others of similar structure/syntax
How do I take a a module with these variables and values and populate them into a listview within a form such as Form1 and ListView1 without continuously going into listview's UI and manually entering the data? The goal is to show the USER a list of 50 cars, their color, door count, cost, appeal, and purchase status.
currently i have created a note pad which contain names
For Example : ( inside the note pad ) Sam1
