Searching And Displaying Specific Records In A DataGrid
Apr 6, 2009
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 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 to write a program that allows a user to input DVD info such as DVD Name, Year produced, Running Time, and Rating. The user then clicks a menu item "New" to save that info to a file. Then the next time the user inputs new DVD info it has to append the new data to the same file. (I got this far and everything is working writing and appending data)Next the year has to be able to search by DVD Video name and it has to print the info in the text boxes on the form, if not found then a messagebox should say not found. When I use the sub procedure that I have created to search the record it always comes back as record not found although the record in in the file.
Option Strict On
Imports System.IO
Public Class Form1

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 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'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 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 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 converted the spreadsheet to an Access database,then used that database in my program.

I want to be able to search the column "Movie Title" for a title input by the user (whether it's the whole title or just a few characters)Here's the code:

I need to accum some data based on whether or not an SSN number appears in the data. I have it in a string, what I need to do is search for a numeric pattern within the string such as:I looked into regex a bit, but I don't have much time to read deep into it (my company needs the program this week) and it seems too complex to grasp in such a short time. What I've came across so far is:
If (rec.address1 Like "###-##-####")
but I don't know if this will filter it out of the string (it can appear with an address attached to it).

I have a program which grabs the source code of a webpage and puts it into a string. I would now like to search the string for two values.
"video_id": "value 1 here"
"t": "value 2 here"
The problem, is that I don't know the position of the values, and I the values change depending on each webpage. All I know, is the text before the value, e.g. "video_id" and "t:"
Here is my code:
Dim videoid As String = TextBox1.Text.Trim
Dim wc As New System.Net.WebClient()
Dim result As String = wc.DownloadString(videoid)

There's an INI file that I want to access and read information from. This is the complete content of the INI file in question: http:[url]....I believe it is because of the [ ] tags in that INI file. Because they work if I remove the tags.My program has a bunch of comboboxes, trackbars and checkboxes. These items will be filled by the information taken from the INI file.For instance, ini file has these lines;
bCrosshairEnabled=1
bDoDepthOfField=0
bFXAAEnabled=1[code]...
Example: I want the checkbox8 in my form to get checked if bFXAAEnabled has a value of 1 or unchecked if it is 0.
