How would that look in a database? and then how would you load the tree. I can load everything up to the grandchild, but as soon as I load the great grandchild I start having issues. So I am thinking it is the way they are in the database.
Private Sub DisplayTreeview()
Try
tv.Nodes.Clear()
Dim i, j As Integer, ds1 As DataSet
S = "select * from Product where PdtRoot=''"

The question says it all, I can connect/Open a Access DB and I can setup a Treeview but how can I bind them together?

sample code or project on how to load a data of a particular table in access database in to a data grid view
View 5 RepliesI'm attempting to create and populate a table in a new Microsoft Access (Jet) database using VB.Net 2008 Express under Windows XP Pro SP3. The database and table are being created properly, but loading the table proceeds VERY slowly. When I am loading the table, no complicating factors that might impact performance, such as indexes or table relationships have been defined. The table to be loaded is made up of relatively short rows consisting of three single byte columns, and one (four byte) integer column. I am loading approximately 16 million rows, and this is literally taking hours, while the same data can be interactively imported into Microsoft Access from a .csv file in minutes. I am trying to batch load the rows, 64K rows at a time, in order to avoid the overhead of individually transacting/committing each row individually, but suspect that I must not be doing something right. Key code that I am using for this process is provided below.

I coded a program to access a Microsoft Access 2010 database. The program is written using Microsoft Visual Studio 2010. I get the error message that the database I'm trying to access is in an invalid format. look at the code below to see what I missed. The error is in the datasource statement.

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I build my project and i got some problems. First i want to print barcode for books(toolstripmenu item). but i cant. here's the code that i found:
[code..]
second problem is printing again. i want to print my MS ACCESS .mdb from child datagridview's records.
third one i want to save and load(with dialogs) my database from main form to child forms' datagridview.and the last one is help provider. i prepare my own .htm help file, when press F1 it opens. but i dont know how to call provider to toolstripmenuitem and help provider keep my computer's path so when i call provider another computer, the programme cant find the path.
For those of you that have been helping me for the last two days thank you first of all, my program is now at the stage where i need to have a windows application that the user can then select databases from, and then using these databases information will be put into a second application that will then run a program to compute some data and spit it into a .xml file.
Is there a prewritten piece of code for choosing databases? And then a set format for choosing cells in that data base to be exported into another windows application?
From a TreeView, I get this XML serialized:
<?xml version="1.0" encoding="utf-16"?>

View 8 RepliesI have started a little program which is linked to an access database, and it basically allows the user to input a name and a picture, with the file path stored in a text box and the picturebox getting the picture location from said text box. At the moment I am using the BindingNavigator to go between data. Everything works fine, however, whenever I press previous or next, the picturebox loads up the picture using the file location of the previous datas picture field. How can I tweak this so that when I press next or previous it loads the picture into the picturebox using the file location of the data I am going to, not coming from? [code]

but now that im looking at the data this is prolly only useful for simple data. Im wanting to seperate the data from queries into multiple boxes. Am i better off just manually having a connection to the database and running queries into arrays to sort the data?? The above method looks like im going to be trying to fight the databound stuff. There are two tables and the way the built in query builder is im starting to think its easier to write my own queries in variables or whatever.
