I need to happen is for whatever is typed in the txtStockBookID text box to be searched in the 'BookID' field in the database (dbStratagem) and for all relevant records to be produced in the datagrid (grdStockResult). The code used above has so far safely connected and displayed the entire table (dbStock) in the datagrid but I am not able to restrict the results to only criteria searched.
I have a problem which I have tried to solve in several ways, and by searching the Internet for various terms, searching through books and Visual Basic instructional videos, but none have yielded the correct results. My goal is as follows:
1. Create a Database listing job names, job numbers, and a link to the file about the job.
2. Create a form with 2 text boxes, a search button, a box to display results, and a preview panel.
The two above steps have been completed. The following is where I get stuck
3. I want to search for either the job name, and/or the job number, have VB search through the database and return the results in the results box.
4. On clicking on one of the results in the result box, the preview panel will show a preview of the file.
Notes:
i) The files being linked top are Microsoft Excel files.
ii) The box I have used for the results currently is a listbox, though I've no idea if this is the correct choice for what I want to do.
iii) The database I created is an *.xml database created in Visual Basic. I am a fair beginner to VB, learning as I go, but I'm stumped as to how to achieve this so any pointers on how to achieve points 3 or 4
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.

I have been taking a class in Visual Basic and am currently working on my final project which I am having some trouble with. I am using Visual Basic 2010 express The project is to create an application that will store data in a text file, specifically, Last Name, First Name, Customer Number, Address, City, State, ZIP Code, Telephone Number, Account Balance, and Date of Last Payment. I have gotten everything done except the ability to search the file by Last Name or Customer Number. I have no idea how to go about this? I was thinking of ways to use indexof or Readline to be able to search the data, but I'm not familiar enough with the code to come up with a good solution. Below is a picture of how my form looks..As you can see, I'm currently using 2 separate forms to get the data from the user. Here is the code for Form1 which is the "Customer Accounts" form in the picture.
Imports System.IO

There isn't enough room to post the code for my secondary form, but you get the idea. I would like to be able to enter a search term in the textbox on the bottom right of the form, and either search the data as its displayed in the listbox, or search the actual file? I was thinking that the results would be displayed in a messagebox?
im just starting to work with some database stuff, and ive got data binding done but im a little stuck with filtering. Ive got a test project, which has
-- listbox (bound to column 2/firstname)
-- Combo box (Has items added, with the same names as the items in colunm 3. so it has 'RPG' and 'Puzzle')
Now what im trying to do is when the item in the combobox is changed say to 'RPG' only items in the db which have 'RPG' in the surname column are displayed in the listbox. Been Google'ing and reading but all i can find is examples relating to a dataview and i cant get them to work/adapt to my situation.
is there anyway i can search for a particular row in all columns in a database and display them accordingly? like in a customer table, i have CustomerID, Name, Address is it possible to search for all the details of a customer?

On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.
View 1 RepliesI am currently trying to develop a program, for personal use, that will monitor the lending of items of music equipments to friends and family etc. And, for my program, I have a requirement, which is the ability to search a relational database, for items loaned, through my program, based on criteria entered in a set of text boxes located upon the program's form. I have already set up the form, and have searched the Internet high and low, to no avail (probably didn't look hard enough).e,I would also like to make another request... if possible I would like to achieve this task with use of the 'LIKE' statement, so that I don't have to input the criteria in full, when I wish to search the database.
The database that I am using is a standard Microsoft Office Access database, saved in a '.mdf' format, and the database comprises of three tables; LoanTbl (which specifies the loan details), EquipTbl (which contains information about the equipment loaned) and a LinkTbl (which forms the relationship between these former two tables) - the reason for the LinkTbl, even though it may seem unnecessary, is because the data has undergone 'normalisation', so that it is stored in the most efficient way possible.
Also, whilst I am on the point of linking together my program and database, does anyone also possibly have any ideas as to ways in which to add data to this relational database; I do have coding for this, however, it only applies to a stand-alone table, whereas there are relationships between my tables.
I am in the process of creating a program that is linked to a database. I want to automatically generate a reference number that is not already present in this database, to do this i know i am going to need to search the database to check whether that number is already present or not. But I am unsure of the best way to go about this. I am using an access database and vb.net.

I`m developing an appication which works with a mssql server database.At this stage I don`t have a problem connectiong to a database, because it`s on my computer.But the release version will be installed on few computers, when after installation user will have to choose the correct database to use with the application. I know how to find a working instances of MS SQL server in LAN, but after choosing an instance how to choose the correct database?
1. How to show databases availabale in th instance?
2. How to separate database designed for my application from all other databases in chosen instance?
how to add and remove entries from a database and now I need to know how to search it. I'm going to be scanning a directory and subdirectories and adding all files found to the database. I need to check if the file has already been entered into the database before adding it.
I though it'd be simple and would just require looping though each entry and checking the item for each entry. I played around with a while loop a bit and ran into some problems. Like when the database is empty.
I don't want to half-ass some code that seems to work, since that'd probably be slow and inefficient.
Also what are the technical terms for a column and row in a database. I'd to use the proper terms in the future.

I know how to search for one specific number from a single line in an access database using a query, but now I have to search through a whole database and display each instance.

search: "1", both results are ID = "1"
results:
