Making A Program That Can Search Through Records In A Database?
Mar 24, 2010
I hate SQL.I am busy making a program that can search through records in a database. The normal search works fine. When I say normal search it means something like this
Code:AppSearchField = "SELECT * FROM StudentInfo WHERE Class LIKE '%" & AppSearchValue & "%'" As you can see the LIKE statement enabled me to search for the items I wanted. now, there is a slight hiccup. Say for example I wanted to add a search condition like AND OR and NOT - it doesn't seem to work.For example, if I do a search like the above statement I get results for Class 1 and Class 10 - which sometimes I do not want, that is why I decided to add NOT etc.
i have a search function in my program in order to find records from an access database... all the other functions add/edit/delete are working just fine this is my code for search function: [code]
How can I create a search box to search records in a sql database? I plan to use the search-box in the same Form where I have a details view interface to the database table.
i am using VB2008 and i need to work out how to search a database. it probably will be very easy but i cant understand it and havent been able to find any tutorials that are for VB 2008, only for other things that wont work, mainly because i dont understand much of what is been written/said/coded.
But the search button (btnsearch) isnt doing anything when the code is tested.

i have a simple application which can create/update/delete/search records using Access database. If i add a record, save it, then close the application and run it again and search for that record, it appears. However, when i write some code to my application, nothing to do with the search function, and i run the application the record is not found. For example i added a button to clear the textfields, and when i ran the application the records i have added earlier were not found.

I was wondering if it was possible to generate fields or details (they are called in IDE) of a xml tables .When you create a database than go into the Datasources and find the table you want than there is a drop down box with datagridview and details.When you select details and than drag the table over to your form ,the IDE creates or the nessiary fields to add and view the data.
If Possible ,How do I do this Using a xml file and at runtime .I have already managed to create the xml as a dataset and view it in a datagridview .But how do I create the fields for the tables .BTW the XML has Multiple tables?
I am trying to search for the occurence of a string within MS Access database with 1000000 records using VB.Net. The program does not respond once it is run or it is taking a very long time. However, if I reduce the size of the database the program runs.[code]...

I have a dataset containing 2 tables,Customers and Contacts. Just showing the master-detail is not a problem. Problem occurs when I try to search the master table to bring in the detail table. Searching the master table shows only the master record, but not the related detail records. Adding a 'findby' query on the detail table only shows the records.url.. Normally when the master table is filled, the detail record shows in a form.
I can retrieve records from my Database fine, but I'm having trouble updating records. I am getting a syntax error on [code] I get this error when I change the Last Name (Row 0, Column 1). [code]
I got a listbox (ListBox1), and I want a search function for it, BUT;When someone search for a string in the textbox, the "Items" in the ListBox will only show the result, nothing else.
This search button works fine, however, in the tooltip it shows "Record Found" as highlighted in the code below. What I want to do is to say how many records have been found. Lets say 2 records found it says "2 Records Found".
I would like to search my database for products from a table(products)The problem is i do not want 600 rows of code with multiple if's.The code looks as following atm(do not want it like this)
Public Function GetSearchResults(ByVal County As Integer, Optional ByVal Searchtext As String = "", Optional ByVal Category As Integer = 0, Optional ByVal SubCategory As Integer = 0) As List(Of Product) Dim dc As New DataClassesDataContext
[code]....
AND alot of elseifs and so on... The problem is that if the value is 0 at any of the above the search will be for all countys/categorys/headlines.... is there a better way to do this? i mean linq is great there have to be a way to make it more dynamic so i dont need the IFS.

I have a MS access database connected to a VB2008 developed software. I want to make a search button to search through all the tables in the database. how can I do this?
I want to link a field in table one to a field in table 2 in the database so that they are the same ( whenever I change what is in table 1 table 2 changes to the same automaticaly )
I have 2 forms in my visual basic 2010 project. Both are connected with an SQL 2008 Server where i keep a db with customers records(name,surname,address, etc).What i want to do is to give certain criteria in the first form, lets say name,and hit a search button. The program should search the db if the specified name exists.If it exists i want to show the results in the second form.By results i mean the name , surname, address,etc. If it does not exist i want to prompt the user to insert data into the db.The problem is that i know how to do this work in a single form but not how to make the two forms "communicate" with each other (meaning that one does the search and the other the projection-adding part).
Edit:I tried setting the filters but all i get is errors. I will post whatever i have written so far in case someone can help me out. So here it is.As i stated earlier i know how to search for the data in a single form(lets call it DisplayForm). As Olivier mentioned i have textboxes for the records, a combo box with the search criteria(name , surname,id) and a Search button that perfoms the search and populates the text boxes. The code for the search button is this:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click Dim intPosition As Integer 'Combo box code Select Case cboField.SelectedIndex
[code]....
I want this procedure be done in a second form (lets call it FormSearch) and populate the textboxes in form DisplayForm.
