View 6 RepliesI want to pull data from database and populate an array. Field one: A short name to call the second. Field tow: A connection string to a database.
EG: Cstr=Connstr("OrDB")
The known name of OrDB would result in a string assigned to the variable Cstr that could be a connection string to an oracle database.

View 2 RepliesThe scenario is i get a string sent to me that i split by a space. Any thing under 60 count when the split occurs it's fine. After that i have a problem.Now there is a lot that needs to happen before we can add this newly split array to the listview.First we need to check what the name starts with. Then assign an icon to this nick.When my server class gets sent this string. Raw Numeric 353 channel names i then send it to my nicklist class.
vb
Private Sub InitiateThread(ByVal nicks As String) Handles _server.NameListEventArgs
Dim thread As New Thread(DirectCast(Sub() DoWorkChannelNicks(nicks), ThreadStart))
thread.Start()
End Sub
Then we split the string and loop each item

Dim nicks() As String = users.Split(" "c)

View 1 RepliesI have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening.

I have been assigned to create a simple address book in VB 2005 and have got as far as I can with it. Contact entries are to be stored as an array of objects rather than to .txt file or access database (I know they will all be lost when shut down). I suspect this is probably pretty straightforward if you know anything about VB - unlike myself obviously.

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?

I am trying to populate a row into a listview control and only the first items shows up (the ProductID). the product name, cost, and quantity don't show up.
I guess the control's properties must be set for this. I went and added 4 columns appropriately named, but those column headings don't appear either.

I need to create and populate a ListView with 3 strings that come from another function. I also want to be able to select multiple pieces of the data to change their values during runtime (is that possible with ListView?).
I've looked all over online for info on this, but I can't seem to find any.
I've seen somethings on GridView as well. Would that be better for this application?
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. I am running into an error while trying to populate this database. The error I am receiving is the following,
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.
