Hi guys,
I've recently started learning VB 2010 and I am currently working on a project that is a Book shop database. The database is an Access database
I need to be able to search the database by Author, Book Title, ISBN etc...
So far I can get it to search one parameter at a time, but i'd like the program to be able to search using a number of parameters, while ignoring the text boxes that I leave blank. I'm an amateur at this :blush:
Here's a sample of the code i've used that allows me to search using just one parameter(Text box).
The results of the search are shown in a second form called frmResults in a Data Grid View box.
Some help and advice would be much appreciated. :)

Dim query = From book In Book_ShopDataSet.Books
Where book.BookTitle = txtTitle.Text
Select book.ISBN, book.BookTitle, book.Author, book.Genre, book.Publisher, book.RRP, book.FirstPublished
If query.Count = 1 Then
frmResults.Show()
frmResults.dgvOutput.DataSource = query.ToList
frmResults.dgvOutput.CurrentCell = Nothing
Else
MessageBox.Show("Book Not Found in Database", "Not Found")
End IfSome help and advice would be much appreciated. :)
