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.
I am using MS access 2003 and Visual Basic.net 2010. I have made a query with the SQl code below. I have set my search button's click to fillbylastname which is my query name. My question is, how do I get it search my database with textbox2's text?uery:WHERE ([Last Name] LIKE '@LastName = %')
I'm creating a rewards system for school where pupil earn points for good behavior which they can then use to purchase things like a packet of pens. (They can also have points deducted for bad behavior). I've created all the forms and now its just getting the data in from the Access database. This is what I need to do. On my form called detailsPupil it shows various information such as Name, email address, last login etc. This form is loaded once the pupil has logged in.
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click Dim Login = Me.StudentTableAdapter1.UsernamePasswordString(txtUsername.Text, txtPassword.Text, cboPermissions.Text) If Login Is Nothing Then MsgBox("Incorrect Username or Password") [Code] .....
That all works but I'm having problems working out how to get the information like Name and email address into their places. This is what I have so far on my detailsPupil form. Public Class detailsPupil Private Sub btnLogOut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogOut.Click Login.Show() [Code] .....
So to sum up I need to run a query which searches the DB using the Username which is obtained from the login form and then displays the Student Name in txtName, Email address in txtEmail etc...
I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" & "*" & CStr(TextBox1.Text) & "*" The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ? or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed. Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function: [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 have created a bookshop website with database, I need a search engine that will search the database records and present the user with results according to the keyword.I have created the page with the text search box and search button.[code]
I have developed an application in VB2008/MySql as database.I did serach record method but i need serach record using(Graterthan) >1000 and <5000(LessThan).Have a look at the normal search record code .
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:
i am creating a search system i have one of y search querys working but when i try to do the same on a different part of the project i get this error message and one of my text boxes underlined message is : -

i have this win form app that performs a database search of customer information. I have a datagridview, a binding navigator and a fill/addquery toolstrip with a toolstrip button and a textbox.Here is my query, i want to find all customer names like what i enter in the textbox
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)
[code]....
COMPANY_NAMEToolStripTextBox.Text is where the the Customer Name will be entered... I originally called it txtName.Text but still even when i changed and did everything through the query builder I get nothing when i run the query.
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 3 textboxes and need to search differently for each of the textboxes. For example textbox1.text is searched in column ans1, textbox2.text is searched in column ans2 and textbox3.text search in column ans3 in table Answer. is there any sql query that can do the search in one button click event.
When i search by forename or surname it works fine but when i search by role i get this error..oledbException occured No value given for one or more required parameters.
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).
I have been trying to create a filter search as instructed by many Youtube tutorials but I am unable to get my code to work:This is what I have. I created a query in the Query Builder like so:[code]So I went back to basics and re-created the Query in Query Builder, this time I executed the query in the QB, but all of my columns are displayed as NULL when I know I have data in the tables.
I am trying to run a search query at wordpress via a webbrowser control, when I enter the search query in any browser it works fine, however when I try the same thing with the webbrowser control in VB the search does not work.
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.
I am making a project in VB 2008 that has a Form (form1) that allows me to add new records to a database, and another Form (form2) that allows me to search for records in a database. I have done Form1 already, but my problem arrives in Form2 where I have to query the database. This form consists of 1 textbox (txt_search.text), 1 button (btn_search) and 1 datagridview (datagridview1). The name of my database is db_extras_test2003.mdb and the table I want to search records from is tbl_contacts.
I know +/- the SQL sintax to query the database (SELECT * FROM tablename WHERE columnname = (here i dont know if i put the variable name i have set for the txtbox, or the textbox itself)).I want this in a way that I (or other users) type in the textbox, hit the Search button and the results are shown in the datagridview (i can show the results in another way if it is better to do so).I have done the connection to the database already. The code I have so far is the following, but it doesnt work
I want to make a search form the user completes the 3 textboxes and 2 datetimepickers. (so five components).
Also I have a button called search and a datagridview.
When the user presses the search button it searches into those 2 tables (depending on what user typed in the 3 textboxes and selected on 2 datetimepickers).
Example of search:
The user searches like this:
When it presses the search button the results will be stored in datagridview(first textbox is the field DB-20-RTS from table PatrimoniuMasini and the rest are fields from the specified columns (name of labels) from the second table FoaieParcursMasina -is the second row from this second table).
Here's the code in my search button (don't know how I can store the 5 things(2 datetimepickers and 3 textboxes in the DataGridView) . My problem is in understanding the property item of DataGridView(DataGridView1):
Dim conexiune As SqlConnection 'conexiune cu sql server Dim comandasql As SqlCommand 'cerere -interogare sql Dim msg As String ' msg- variabila dk suntem conectati sau nu
i'm currently making a client database program for work that stores data in multiple text files (so that the information won't be confused as to which info belongs to who in the database). Each client has his/her own text file, which isn't really a problem although i realize it's a bit messy. A listbox holds items, each item a person's name.When the listbox selected index is changed, the streamreader opens the corresponding textfile, which is as such: "John Doe.txt", and populates the correct textboxes with the information stored in "John Doe.txt".What I'm unfamiliar with is implementing a search function.
1. search query entered
2. streamreader reads through all txt files in a directory looking for matching keywords.
3. if a match is found in a txt file, it looks at the name ("John Doe.txt"), gets the corresponding listboxitem, and finally, once the textboxes have been populated with the info in the file, highlights the matching keywords.
4. then i figured if there was more than 1 match over more than 1 txt file, you could repeat the process and skip to the next match via the tab key (like the find feature of a WebBrowser or other such application).
What i don't understand is how to read multiple text files, search in keywords, highlight the matching keywords, or the tab function..I know that's a lot to ask on a forum, but I had nowhere else to turn.
I am trying to do a search on a index/row number taken from a dataview i.e. I enter 379437 in the input box which I know has a index/row number of 6. Now when I replace the Rows(index) with a Rows(6) I get the results that I want. When I run the code below the index comes out as 75 which displays the first row from the dataset which is a completely different set of results.
I have a search function de build.We are using pure ASP.NET w VB.NET We have multiple DropDownLists and we're building a search query with whatever was selected in those DDLs. My question is, how can I handle the blank values (unselected dropdownlist values) with the SQL Query ? I'm using AND operators in the query so if anything is blank it'll fail the search. If the dropdownlist has no selected value, i don't want the value to be part of the search. It would be easy to code with just 2-3 parameters, but we're looking thru at least 10 items and doing a SWITCH CASE or multiple IFs would soon become mayhem.
I am constructing a search function in a class to be used by several of our asp pages. The idea is simple, take a search term from the user and query the database for the item. Currently I am doing this the wrong way, which is vulnerable to SQL injection attacks (and ELMAH is in there to save the day if something goes wrong):
[Code]...
The problem is since I am using a like statement, I need to be able to have % on either side of the search word, and I can't seem to do that with '%:searchterm%', it just gives an error of ORA-01036: illegal variable name/number.Can I parameterize but still have my flexible like statement be a part of it?

Im trying to figure out how to query a dataset when I select multiple values in a list box? I have the list box linked to the dataset and am using a button to search the values selected in the list box. I don't know what to do!
