I have a table in an access database that binds to a datagridview with a binding source. The table is named Charges and contains all the charges to a lot of accounts. Let's say I only want to display the charges that are associated with Account ID = 1.

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

View 7 RepliesI've created a database in Access 2007 and connected it to Visual Basic 2008. My database have tables Coachee and Coach. Details of Coachee are displayed in one form and there's a button that when clicked will show details of the Coach of that particular Coachee in a another form. If the Coach is not in database, user will be prompt to insert a new Coach record. Problem is, when saved, the newly inserted record will not be displayed and i have to exit and rerun the program, only then the record will be displayed.

View 2 RepliesI used following code searching records from a table in MsAccess and displaying in a Listview and it is working fine with the search criteria based on Discription.
CODE:
I also tried the above code to search records on the base of CustId and it worked fine too.My table DailyTransaction in MsAccess is as under:DTDate, DTTime, CustId, Description, Quantity, Price, Amount, AccountNumber, Name
Now I want to Search records on the base of Date I tried the following but it did not work.
Dim cmdText As String = "SELECT * FROM DailyTransaction WHERE DTDate=' " & TextBox1.Text & " ' "
Also i want to make following sort of query to retrieve data between two dates and to display the sum of amount group by DTDate. I could sketch following query and deifinitely it is so wrong with Syntex.Select * From DailyTransaction where DTDate Between textbox1.text AND textbox2.text Group By DTDate AND SUM(Amount)
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.
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.
Here is what I have so far, the database has a column with just the doctor names so I thought I should be able to filter it by that and show the patients, but none show up. I don't get an error and it seems to refresh, but nothing ends up in the schedule.

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
Dim Provider As String
Dim Source As String

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".
