I have a delete method for a binary search tree. It only deletes the last two entered values. When trying to delete the root or anything to left of it it returns a null pointer exception.
PublicFunction Delete(ByVal key AsInteger) AsBoolean Dim current AsNode = root Dim parent AsNode = root Dim isLeftChild AsBoolean = True While (current.value <> key)
parent = current If (key < current.value) Then isLeftChild = True current = current.rightNode Else

How do I use the Indexof Method to search for an Index a number? The number will be different on each line of the file. Each array has a name and a different zip code. I want to tell it to search for the first number in the line. Everything before that index will be first name, last name, and then zip code.

I have a SQL 2008 Express database, which have following tables: [code] Now I need SQL query to search for word (i.e. Beyonce Halo Music Video) against these tables.
-For Title exact phrase will get 0.5 points
-For Description exact phrase will get 0.4 points
-For tags exact phrase will get 0.3 points
-For title all words will get 0.2 points
-For description all words will get 0.2 points
-For title one or more words will get 0.1 points
-For description one or more words will get 0.1 points
And I will show these videos on basis of points. What will be the SQL Query for this? A LINQ query will be more better.

Is it possible to Query or search or anything for a DBX file. We are looking to be able to pull out the Sender, Subject, Date of Arrival, Yes/No Attachment, and the body if possible of the message. I've found a bunch of programs online so it seems possible, but how do you do it? I'm currently using VB 2005 but could work this out in C# if VB isn't a good option.

I'm attempting to query an Access database using a search button from a textbox and insert the results into a listbox. Here's the code I have so far:
[Code]...
The problem I'm having is it's returning the both InstName and the StuName multiple times in the listbox. I'm guessing it's because I'm doing the items.add twice? I was trying to use "[oledbcommand variable name].parameters.addwithvalue" but I couldn't figure out how to do it with a "like" function.

Trying to figure out the right way to query a MySql database and find a user defined variable from a Textbox.Text property. I'm not sure what to put for the where clause in order to search every cell of every row for a match. I have looked at coalesce and contains, but neither are really making sense to me and I'm not sure if they are my best option. I'm thinking that the query string will look something like this:

SELECT ACCOUNT_NUMBER, COMPANY_NAME, COMPANY_ADDRESS, BILLING_ADDRESS, CITY, STATE, ZIP, COUNTRY, PHONE FROM tblCustomerInfo
WHERE (COMPANY_NAME LIKE @COMPANY_NAME + N'%')
i am using sql client with a datagrid and i already bind the data to the grid as a dataset automatically so i did not manually code the connection, cmd, dataset ect here is the find button code that recieves the customer info according to the sql query
Private Sub FillByToolStripButton_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FillByToolStripButton.Click
Try
Me.TblCustomerInformationTableAdapter.FillBy(Me.CoCustomerAccountInformationDataSet.tblCustomerInformation, COMPANY_NAMEToolStripTextBox.Text)

I watched a video from Beth Messi about creating a search function using query builder.
For instance, if I want to filter FirstName, I will do " LIKE @FirstName + '%' " - the FirstName's datatype is varchar My question is, what should I write for the "int" datatype?

I 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.

I have a VB.NET search routine, part of which is provided, below, that checks all Text cells in a DataGridView for a given string (inclusive), using a basic set of nested loops to perform the search:
' Search for the first occurrence of the given string
For Each row As DataGridViewRow In dgvMembers.Rows
' Skip the new row
[Code].....
is there a way to replicate this behavior using LINQ? Basically I would like the query to select (or return) the first DataGridViewCell whose text contains the search string. I've done some tinkering with sub-queries and the like, but I'm still having trouble wrapping my brain around the concepts (too many years of writing T-SQL, I guess).

VB.Net 2005 SQL server 2005
I have a project I have a dataset that contains tables In the dataset designer, each table has a defaiult FILL command set. I have draged and droped my table as a grid onto my form VB automatically sets up the table adapter, and binding source to make it all work.
in my code, is placed in the form load routine, a tableadapter.fill(dataset.datatable)
Here is my dilemma. The data in my table may have 100's of thousands or rows.
I have presented the user with a front end that allows for filterring and selecting based on several columns. reguardless of how many rows the result set contains, there will always be the same columns in the dataset.
Because there are so many combinations of select query, i do not want to make 20 or 30 custom fillby's in the dataset. I want to make an addhoc select query and have the binding source and table adapters work as expected. I have created a query called "FillByCustom" in the dataset designer attached to the DataTable Adapter section.
My question is this.
If i build a select query that returns the desired rows, how do i place it into the adapter in place of the FILLBYCUSTOM select command, such that it all works as expected?

I am trying to do a SQL query that checks for the presence or absence of a character's occurance in a field / column as a condition to retrieve the row. In this case I only need to test for existance of the specified character and in a similar query to test for the non existence. Not where it is or how many, just is it there or is it notI am using VB express.net 2008 and it uses, I think, MS SQL Server 2008.Using VB's instr() I can tell straight away if a string does or doesn't contain a character, but I would like to know this before I retrieve the row.
using the
WHERE .... and [mytable.myfield] LIKE 'Q'
or
WHERE .... and [mytable.myfield] NOT LIKE 'Q'
produces a result, but not a correct result. It does something but I can not say that it is working even part way.CHARINDEX gets an undefined function error MATCHES also gets an undefined function error?CONTAINS looks like it should work but I am still getting sytax errors with it, so I don't know how to use that predicate yet.
