Simple Databse Question.

This link will have everything you need to know about what you need to do:

If you look on the left pane you'll have topics like " Update a Database from a DataSet" which is one of your queries. Plus there are plenty more useful links. Hope that helps.

I appreciate the link but wasnt what I was looking for, But here's something else to add to this question,
would it be possible to bind a table to a structure?

public structure bot
dim address as string
dim nick as string
end structure

dim bots() as bot
redim bots(db.rows.count) as bot

and then bind the two fields in the database to bots().address and bots().nick with maybe a loop?

and have new instances of bots() be recorded to the db ?

i am not sure whether you can bind to a structure, but definitely you can bind to a class, by just inheriting it from control. Take a look at the followin example --

PUblic class bot
inherits control
dim address as string
dim nick as string
end class

dim bots() as bot
redim bots(db.rows.count) as bot

bots(0).databindings.add("address",dataset,"tablename")

Well in your case i think the best way is to have a Dataset with two tables.
The dataset will be disconnected so yuo need just one connection say on Form Load and fill the Tables in the DataBase.

As for the tables where you'll have heavy DataEntry, You can have the Entries in disconnected mode (Unless of course where you have an AutoGenerate Primary Key and more than one Users, in such a case you'll need some concurrency measures)
After all the entries are done database connection can be opened and all data stored back.

Now for the table from where you need to search often, You can use DataViews to filter the records in the second table giving where clause like "lastseen = 'Two'"

I prefer to use dataView objects, in different comboBox objects you can select the search criteria from them and then update the rowFilter property of your dataView, when I want to filter very fast, i do this.

Well, I fill the comboBox objects manually, because if I do this in that way, I can add an 'All' item to indicate that that criteria will be discarded.

eozz: can you say all that again in a tad more detail, and maybe show some sample code?

you guys have been very helpful, thank you all.

Ups, well, the code could be so large... but with this explanation I think you'll understand:

-Suppose that you have this table Products(Name, Size, Cost, Color)
-You must create 4 comboBox

The code of the first comboBox is this:

dim com as new OleDbCommand("SELECT DISTINCT Name FROM Products",Connection)
dim dr as OleDbDataReader = com.ExecuteReader()
while dr.Read
    me.cbName.Items.Add(dr.Item("Name"))
wend
me.cbName.Items.Add "All"

You must analog things to fill the other comboBox

-In the selectedIndexChanged of your comboBox objects you must do something like this:

me.ApplyFilters()

private sub ApplyFilters()
    dim bolFirst as Boolean = True
    myDataView.rowFilter = ""
    if cbName.Text <> "All" then
        bolFirst = False
        myDataView.RowFilter = "Name = '" & cbName.Text & "'"
    end if
    if cbSize.Text <> "All" then
        if not bolFirst then myDataView.RowFilter &= ", "
        myDataView.RowFilter &= "Size = '" & cbSize.Text & "'"
    end if
    if cbCost.Text <> "All" then
        if not bolFirst then myDataView.RowFilter &= ", "
        myDataView.RowFilter &= "Cost = '" & cbCost.Text & "'"
    end if
    if cbColor.Text <> "All" then
        if not bolFirst then myDataView.RowFilter &= ", "
        myDataView.RowFilter &= "Color = '" & cbColor.Text & "'"
    end if
end sub

I am actually trying to avoid putting any information in objects like listbox/combobox, I would prefer to do it in all arrays, but, my question now is, is arrays amounting to over 15000 to much?
