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.

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 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 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.
