I tried to show the rows of the table I created. First I added a bindingsource object and selected my database and table. Then I added a textbox and set databinding>text to the item i wanted in the table. In the begining it worked but then it suddenly stopped working and even though I built the program again from scratch it no longer works.

It's apparent I have no idea what I am doing anymore, therefore I'm turning to experts. I would like to 2 things.
1) Make an ODBC connection to our datasource and display it in a Datagrid (table)
2) Make an ODBC connection to a DataSource and Copy several tables to an MDB file. Basically the same thing I accomplish by using the Import Function in Access. Just automated and with some additional items.[code]
In trying to answer the first part of my 2 part question, this is as far as I get. I can't seem to loop through the ODBC connection and assign it to a Datagrid.I usually get an Transoft Error about the Query - or more often I receive ERROR [IM001][Microsoft][ODBC Driver Manager] Driver does not support this function.[code]

Transact(tablename) - Transaction_No(primary key), ISBN(foreign key), Student_ID(foreign), Date_Borrowed

I am querying the MS Access Database to display the results in a datagridview. This is my
Dim ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=data.mdb"
Dim SQLString As String = "SELECT * FROM Groups where Selected = Yes"
Dim OleDBConn1 As System.Data.OleDb.OleDbConnection = New System.Data.OleDb.OleDbConnection(ConnString)
[code]....
The variable Selected from the query statement ("SELECT * FROM Groups where Selected = Yes") is a Boolean in the MS Access Database. However, this statement returns empty result even though most of the values for Selected are Yes. In the access database however, if I enter a 'Yes' for the value of Selected, it shows up as -1 and 'No' shows up as 0. So I even tried changing the query statement to ("SELECT * FROM Groups where Selected = -1") and also ("SELECT * FROM Groups where Selected = 'Yes'") but none of them work. Can you please help me fixing this query because I can't change the database?Also if I change the query statement to ("SELECT * FROM Groups"), then all the data shows in the datagridview, however, the values for Selected column do not display. Instead I see check boxes and I can't click them. How can I display the values correctly?
I have two Access database, say database One.mdb and Two.mdb. I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset
View 1 RepliesI am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

View 1 RepliesI'm currently attempting a project where I need to display a series of images from a database, in thumbnail form, then fullscreen when they are selected. Next/Back arrows will be used to navigate through different pages of images. These images will be across a number of categories each one with a different table in the database. It is very important that the user can change the images in the database.
Rather than have a number of different pages and each image designated to a picturebox, I was wondering how I could make it so the program just displays the next 6-8 images from the database in the same picture boxes, giving a message when the it reaches EOF, This way the number and order of the pictures can be changed just by changing the database.
I want to be able to use this program to filter through a list of doctors, and based on what doctor you select, only show the patients who see that doctor.

I seem to be having a problem with displaying data in a second form. I've created a linear search algorithm which works just fine - it locates the records from the database. I now want to be able to display the record in another form, I've attempted this using the code below but it doesn't seem to work:
Public Class formSearch
Dim searchItem As String
Dim currentRecord As Integer

The commented out lines are the ones that don't seem to work. The "txtfirstname" and "txtlastname" fields are located in the coding of another form, called "formcustomers".

A simple database has been created in Access, which is just basically a table of text, with some images as entries. A form has been created in VB2008 Express and linked to the database. Either a combibox, text boxes or pictureboxes are linked to a column form the database. The first row entries are all displayed correctly in the relavant boxes (except for the images, which for some reason aren't displayed). If another value in the comibox is selected, the other box values don't change and there is still no images visible...
View 1 RepliesI just starting coding in VB.net about two weeks ago so I'm still a begging and I learn best by seeing working code and then adapting it to my situation. That being said, I need help displaying table entries in a listbox. I've successfully created a database in my test application, added it to my Data Sources and used a drag / drop method to add Datagrid View & Details (labels & textboxes) to my application for testing purposes. Now I want to try and display table entries in a listbox.
Example Database:Table: Contact
- ContactID (autonumber) [primary key]
- FirstName (text 50 limit[code]....
Also is there any benefit or down side to creating a database in MS Access, create the relationships & tables, then attaching that database to my application or is it better to create the database in the application like I did in the example above by using the Add New - Service-Based Database option?
