Asp.net - Use QueryExtender To Search For Term Across Multiple DataFields?
Apr 6, 2011
I have a textbox with button wired up to a queryextender. My goal is that someone might enter into the textbox a name (e.g. "Dave Mackey") and receive back all relevant results. The problem is that this information is spread across two columns in the underlying database (e.g. FIRST_NAME, LAST_NAME). My code looks like this:
If I enter "Mackey" it returns results, but "Dave Mackey" returns no results, I'm assuming b/c it is looking for the entire value in one first (either, but not both together), whereas I want it to return any rows where it finds the entirety even if it is spread across multiple DataFields.
I need to search a term in pdf file to get font of all occurrences of the term with its corresponding font information and next 5 words of each occurrence.
I'm trying to create an application that will allow me to type a search term, corresponding to any field contained in a database, and have the results displayed in a datagrid view. The idea is that the application will display any records that have the search term in any of the fields, rather than just allowing the user to search based on one field only.
I keep getting an error on the dataAdapter.Fill(dt) line. I've tried reorganising lines of code just in case my logic was wrong, but the result is the same. The program just crashes when it reaches this line.
My code is:
Public Class Form1 Private Sub AuthorsBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AuthorsBindingNavigatorSaveItem.Click Me.Validate()
Im trying to make the below statement as such if there is no items selected/blank then the search term is a wild card (all results) otherwise search it. the sql below only works when all fields match, not partial
I have an Entity I'm pulling three columns from Title (nvarchar(256)), Popularity (int), and Type (int). I'm then trying to use QueryExtender on a radiobuttonlist to allow the end user to filter out all but specific results but I keep getting an "Argument Types do not match" error. Here is the actual code:
changing the way the site search is done from just search a phrase as one string to searching a phrase "as multiple words" search. For example, if I search "cute puppy" right now, it will search it for "cute puppy" as phrase and won't match just "cute" and "puppy". The way the search is implemented is by passing a search phrase to a Stored Procedure in SQL Server.So now, I need to change to site search so when "cute puppy" is searched, it will search two words.... "cute" and "puppy" instead of just "cute puppy". Below is how the store procedure is implemented
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.
what is the term used for such as event?'.What I am trying to do with open a application config form in login window which is activated by combonation of keys pressed. for example alt+c or ctrl+alt+x.
Is there a way to get the IntelliSense for a lack of better term to work like it does for C#? For example, lets say I want to add a MessageBox to my form. With C# as soon as I get around Mess it's already coming up with the rest of the word, and the same with variables and control names. Just wondering if I'm missing a setting or something some place or if this is just another example of how things are different between the enviroments. Using Visual Studio 2005.
Learning VB.net and the framework.Read a few books, but none have actually labeled graphically the anatomy of a code line. [code] Obviousy Dim is the Dimension or referencing the variable.What is the specific term for the date.now() command?Is that a vb property or expression?The operator is Do, As, and loop right?What's the regular term for just a simple line and what is an expression when speaking of this code block?There should be a list of the date.now() properties easily available in a regular list somewhere.
I would like to search for a member using a text box. i have connected my vb form to an MS access database.I have the following command so far however i would like to search for the forename or the surname, not just the forebame.
Every table I have has an 'UpdatedBy' field which lists the user who last made an update to the record. I need a way of searching every datatable for that username and returning the count of the rows where the LastUpdated field is equal to a parameterized username. How can this be accomplished without writing a seperate query for each datatable that does the same thing and running each query one at a time? I'm not sure if this can accomplished somehow in the dataset itself or if a SQL Function could do this.
I am doing a simple database project.I need to give the input in the database which is an access db from my input form and i have managed to do this part right.then i need to retrieve the details from the db using multiple search fields and show them in the datagrid view.I have 8 search fields(5 textboxes and 3 combo boxes). I also have included 4 other buttons which respectively clears the search boxes;clear the results of the gridview; show all results from the database;go to the input form and offcourse 1 search button.now all the buttons working fine except the search button. actually when i click on the search button if i include sql query for all the search fields only the first one works and also if i have clicked any other buttons before clicking the search button nothing happens, no result is shown and it happens the same if i search once and clicked any other buttons and come back to search, no result. I need to show the results in the gridview depending on the user input on those search criterias. user should be able to search in any combinations.I am using the below codings in my search form. the combo boxes are not bound.datagrid is bound to database though.
Public Class Paxsearchfrm Private Sub Paxsearchfrm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'TODO: This line of code loads data into the 'LAFDataSet.Table1' table. You can move, or remove it, as needed. End Sub
I'm trying to write up an implementation plan.I'd like to write something like:Due to the high-level of spaghett-code in the existing program..But I'm not finding anything that even remotely looks professional.
Public Sub theConnection() Try conString = "DSN=XXXXX;UID=XXXX;PWD=XXXXX;DATABASE=XXXXX" con = New OdbcConnection(conString) Catch MessageBox.Show("Connection to the Spec Database was not made")
i am creating a program in vb.net and was wondering if there is a way to perform multiple queries with one button without adding a second button. like i have two text boxes, one is for date and the other is for name. what i want to do is if i hit search and both the date and name boxes are filled, i want it to search for the name based on that date. but if only the name is filled i want to search for everything under that name.This is what i have. right now it only does one search:
When you do GetFiles() you can specify a search pattern such as *.txt. How can I specify multiple patterns. For example, in windows search you do *.jpg;*.bmp;*.gif. I tried that but no luck and the msdn not work. Is this possible?
I am trying to search one column (Titles) of an Access database using an SQL query. The search entry comes from a split string passed to an array and inserted into the SQL command. This works well, however, the results I get back are for entries containing EITHER of the keywords entered, not entries containing ALL keywords entered.
The code I am using is::::
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click dgvSearch.Visible = True
[Code]....
The loop is working, but acting as a new search as opposed to searching the results of the previous search.
is there a way i can get my datatable to have multiple constraints that are attached to a unique id? an example of what i'm talking about is if i have a unique machine but it's on many lines, can i show that somehow in a datatable? the reason i'm asking is that i have code that sorts the data by line number and shows the relevant machines in a combo box based on the line selection out of another combo box. i'm having to input the data into the datatable (as a starting point for the data base) and it's very tedious. i'm entering machines that have the same name in multiple rows because the line number is different. i can't figure out how i can add multliple values into my line number column so that it will sort properly when queried.an example of what i'm asking with regard to the datatable is as follows:
Machine LineNumber slicer Line 1, Line 2, Line 4 conveyor belt Line 1, Line 6
So that when called to fill the combo box, the correct one is called.The code i'm using to sort right now is as follows:
Private Sub linecbo_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles linecbo.SelectedIndexChanged Dim cline As String

Path = "C:" For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.10") _ And For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.09") 'do code
Next My goal is simply to search for multiple file extensions. I cant use FILE* as my search parameter as this returns other files e.g FILE2012.10z which i don't want.
I'm trying to find out a way to search multiple arrays for a specific value. I looked through here, yahoo, google and msdn and couldn't find anything specific to what I'm looking for. Don't have any sample code as I'm not quite sure where to start.
I've used an OleDbAdapter to connect to a MS Access database with about 17 fields. I want to be able to search between 1 and all 17 fields for return(s). I have been able to search 3 fields so far (so all 17 will not be a problem), but all 3 fields must be completed or an error occurs (FileNotFoundException was unhandled).[code]...
