VS 2008 Searching Through Records In A Data Table
Jan 13, 2011
I'm trying to write code that allows a search for a particular record in a data table. The table, imported from an access database has 4 columns, the first being names of cities. I need to search for a particular city and have it display the city name and the other three columns of data for that row in particular text boxes. Here is my code...it is the last sub routine that is the problem...I'm tying myself in noob-ish knots trying to figure out nested loops etc to search... (I've commented some of it out whilst I tried to figure it out but I'm running out of time and patience and my knowledge of VB is limited!!)

I have a form that reads the data from the database table ( so you can see I have figured out how to attach to a databse table)On the form I can scroll through the data with use of the binding navigator that VB automaticly installed on the form, but I need to search the table for specific data in one field.I am guessing that one way is to use a query, but I can't figure out how to use one.I realize that this may be real simple, but because I am just learning VB, I don't know where to start.

I got a problem I need to search by First Name OR Surname. So the user can enter one or the other or BOTH.
So here's what I got I set two primary keys to try and find the row but I'm gettin all sorts of problems, for example when I set FirstName & Surname as primary key which you need to do to use the find method i get an error as it expects two values..
Dim da As New SqlDataAdapter
Dim con As New SqlConnection("Data Source=UserSQLEXPRESS;Initial Catalog=StudentTeacherDB;Integrated Security=True")

In general Combo Box looks for the strings in the list that Start with the text that typed in the textbox portion of combo box.
I want a feature in combo box which do not just look in the starting of the strings, insted they shold search the maching strings within any part of records i.e. If User types 'Ja' in textbox portion, the the list should show following maches with highlighting the mached records
Micle Jackson
Sandeep B Jakhotya
Javid Akhatar
Suresh Jadhav
Jackie Chan like this.
Similar control is already used by Yahoo Web Site for Search Assistance in its Web Search Combo box. Here if we type say 'bush', it will populate following records
george w bush
jenna bush
bush shoe
bush game
hot dog bush
I want the same with Visual Basic for Windows Form Applications.

I am having to create a data adapter to pull data into a dataset, then loop through that dataset in order to add information into a new column from a separate data source. My first data source is access. My second data source is oracle. Here is the code I have to do this, which works well when I show it in a grid.
Dim da As New OleDbDataAdapter("SELECT tblSummary.WorkOrderNumber, tblLabor.Crew, tblLabor.NumberOfMechanics, tblLabor.NumberOfHoursPerMechanic, tblTasks.TaskNumber, tblTasks.TaskDescription FROM (tblLabor tblLabor INNER JOIN tblTasks tblTasks ON tblLabor.TaskID=tblTasks.TaskID) INNER JOIN tblSummary tblSummary ON tblTasks.JobPlanNumber=tblSummary.JobPlanNumber WHERE
[code]....
how I can search through this data table. For instance, I want to see only rows that are in this data table that have "Replace" somewhere in the "Description" field, which is the field I added from my second data source. How do I do this? Is there an easier way to do all this instead of filling my dataset from the first source and then adding columns from the second source by looping?

I want to iterate through the records in an SQLCompact 3.5 data table and combine the field values into a string.The database file is connected to the project.I created a dataset that contains the tables from the database.If I drag and drop any datasource table as a grid onto a form I can view the data.[code]I have tried using the tableadapter.Ran into errors when the Date2 value = DBNull, never could get around those.I've tried dataview and datareader on the dataset.datatable but never could get these to load any data rows.I could sure use an uncomplicated unconvoluted way to simply read the rows of data in a database datatable.

I have a database with 3 tables: Student, Unavailability and Duty.The fields for Student are entered in a form I have. One of the fields in Unavailability is filled by a form, the other fields are an autonumber and a foreign key to the Student table.ow I want records in the Duty table to be created and automatically filled in depending on what the values of the fields are in the Student table.For example, If the Boarder field in the Student table is 'yes' then I want the Duty Number field in the Duty table to be '1', '3' and '4'. If it is 'no' then I want the value to be '2' and '5'. I recognize it will have to create several different records to incorporate the different duty numbers for each StudentID. Obviously this will require an if statement, however this is my first time implementing a database with my limited experience with programming and Visual Basic, so I don't know how to refer to the specific fields in a table and set the value of other fields depending on the data in other fields.

Ok I have a search Button that will search through a student table and produce the grades of all the stdents in a class room when I enter the class room number into a textbox(txtclass.Text). The results will be displayed in a DataGridView and also I have the average grade of the class displayed in another textbox(marks.Text).
My program runs fine but I would like to add more code so that If I enter a wrong classrom number into the search textbox and Search for it then I would like a messagebox to pop up and say that the classrom you have entered does not exist. .I have tried different if statements but none has worked for me so far.

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

I need to search a keyword put in a text box. In my case, I want to search records by the month name. I would want a command button that displays results according to the keyword typed in a text box. Now I tried two methods, one with a text box, one with a query. Both Do search, but the fields return empty.
Heres the code for my form where the datagrid is:
vb.net
Public Class Form6
Private Sub Pay_CalculatorBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Pay_CalculatorBindingNavigatorSaveItem.Click
Me.Validate()

I am coding on Visual Basic 2010 and need some My Access database table has following information:
FirstName
LastName
PhoneNumber
Basically what I am trying to do is create a Search function where the user will enter a First and Last Name in the search boxes and upon hitting the ''Search'' button the program will look through the database and check if the records exists.
If the record does exist then I want the Phone number to appear in a separate textbox which is named txtPhoneN. I have included the code I use to connect to the Database. I have already managed code the part to Add new record to the database.

I have this piece of code wich works perfectly when inserting records into one table using records from another table. My question is that now i need to create another table by using records from 3 other tables (tables are related). Can i use aliases on the column names, like on Oracle SqlPlus? How will be the syntax of the 'INSERT INTO SQL statement?

I have a problem finding strings that do not exist in a column in a database. I am going to use linq but its more the 'way' of doing I am concerned with.
I have strings like;
MEAL
GPST
EXLEG
EXLG ...etc
I need to find records that does not have this list of strings in, so for example DBML BUT sometimes I can have the string MEALDBML, or more concatenated. So this is a known string of MEAL and unknown string of DBML. I would then want to see that record. I do not know the unknown strings up front, so its a case of feeding in the strings I know are ok, and finding one that are outside that list. I was also thinking of regex?

I do this in Oracle databases just in a snap, but now I have to do it in VB using ADODB and I don't know how to do it.
I have two Access 2007 tables. Table A contains: Col1 (text), Col2 (text), Col3(date), Col4(amount), Col5(text)
Table B contains Col1(date), Col2(amount) What I need to do is to insert into table B the records of table A (col4 summed) grouped by date of table A. The date is a variable contained in a text box so it cannot be hardcoded into the SQL statement.

I am pulling the computer model from the bios, the passing the result into some SQL to find it in a table (as the bios name, and the names in the database are different).If it exist, it writes the value from the database to a combo box (cbModelBios)I am trying to debug the case where the computer model does not exist in the table.I figured I would just try to see if the SQL statement returned null, but I am still getting an error [code]

I have an application where I need to be able to search for the workers related to a company from a contacts list. I am able to do this by entering the company number but I am unsure how I can set the query to allow to search for the information in the other table.
[Code]...
SELECT RecordNo, CompanyID, AccntRep, CustNumber, Person, SubjectID, StatusID FROM dbo.Contact
WHERE CompanyID = @companyNo I think that I need to create a join in the SQL statement to the company table but am unsure how to go about this and I would be grateful if someone would give me a point in the right direction so that i can search for the company name instead of the companyID.
