I am currently trying to create a search function on a page in VB.NET which will allow me to search a database for a customerID from a textbox called txtSearch and then present it into a datagrid.
So far I can display the customerID's manually by using
SELECT * FROM Customers WHERE CustomerID LIKE 'A%'
but cant figure out how to replace the A with data which will be inputted into the textbox.
I'm creating a search function to search through a binary file and find a record based on the users input. Surprisingly, that isn't the problem! The problem I'm having is that as part of this I'm using a procedure to display results in text boxes, and I'm getting the error "Too many arguments to private sub display customer"I've encountered this error before, but never really knew what it was... Here is my code.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
FilenameCust = "F:\College\CustomersFile.bin"

Im making a search function for an application and they need to be able to search by any value in the DB in any of the three tables. Im wondering the best wayto about this. 2 of the 3 tables have the same columns while the last one is totally different. Below is what I kinda "thought" itd look like but no.
"SELECT * FROM cases, opencases, staff WHERE Crime ='" & txtsearch.Text.ToString & "'"
I need to query the results the user can search for anyterm and if it matches something in the columns it return it to the user. Im wondering if the best way to go about this is to maybe query all the tables and then put all the matching records in a seperate table and the dgv look at that table or how to exactly go about it.
im trying to implement a search function to my booking program, wich retrieves data from a SQL database. I have the screan all set up and all the variables at the ready, the only problem is, im not sure how to execute it in a sqlcommand line.

How would i write a sqlcommand to search for available rooms that meet the criteria for the room to be booked?

View 2 Repliesfilling an OleDbDataAdapter.I have:
Dim cmd As OleDbCommand = New OleDbCommand(myQuery), myConnection)
Dim da As OleDbDataAdapter = New OleDbDataAdapter()
Dim dtDonnees As DataTable = New DataTable()
da.Fill(dtDonnees)
Filling takes too much time.For 20 lines it takes 20 seconds.And for 130 000 it takes a little more (but not 130 000 sec).But 20 seconds is too much anyway.
Question part 2: can I skip fill?I mean, after filling the datatable, I do a for each row of datatable and cast into an entities:
Dim returnList As New List(Of myObject)(dtDonnees.Rows.Count)
For Each rowDonnee As DataRow In dtDonnees.Rows
returnList.Add(New myObject(rowDonnee))'set every data of the row into my new object
Next
Can I pass each row of OleDbDataAdapter?
I have a field in a 2003 access database named first. I run the data adapter update command, gives me "Syntax error in UPDATE statement." I change the field name to firstName, try the update again, it works. I already have a bunch of programs using the database and using the field "first", do I really have to rename my field, go back and update all my programs to read from firstName instead of first? I really don't want to go that route if I don't have to. (provider=microsoft.jet.oledb.4.0)
*Edit: I meant to specify, I want the answer to use commandbuilder (but it won't work that way).

I have had this headache for a few days now. Thought I had sorted it but haven't.I have copied worksheets from an excel workbook into a dataset, with each a datatable for each worksheet.
I then use a DataGridView to Display and edit the datatable.DataGridview.DataSource = MydataSet.DataTable(0) sort thing.But for some reason I just cant figure out how to write the datatable back to the excel worksheet.I have this but Im probably barking up the wrong tree.

View 1 RepliesI tried out the video tutorial from Beth Messi about how to create a search. The tutorial teaches us how to do it through query builder in which we just have to type LIKE@fieldname = '%' for each field we wish to appear on a toolstrip. A toolstrip menu will automatically be generated and placed underneath the form bar for us after we click ok.
Now, I would like to know how can I do this with code? I can use a code which will move the auto generated toolstrip into the tabcontrol but when I have more than 1 tabcontrol, that's when I start having problems - the toolstrips are starting to cover up the tabcontrol. I know I can move the datagridview lower but that is going to leave a big space above it.

View 1 RepliesI am writing a program and I have the Read Function all written out. I need to have the write function. I think is I copied and pasted from the Read function I wrote.
I was able to Mass edit This:
Reader.Position = (&H)
NumericUpDown281.Value = Reader.ReadInt16()
Reader.Position = (&H)
NumericUpDown280.Value = Reader.ReadInt16()
Reader.Position = (&H)
[Code] .....
And there is at least 370 NumericUpDown's. Is there any way to search/find/replace all in one instead of typing:
Find what: NumericUpDown320.Value = writer.WriteInt16()
Replace with: writer.WriteInt16(NumericUpDown320.Value)
Each individually?
The write function will only write properly this way:
writer.Position = (&H)
writer.WriteInt16(NumericUpDown66.Value)
And not this way:
writer.Position = (&H)
NumericUpDown319.Value = writer.WriteInt16()
