Where is your data coming from ? It seems pretty straightforward to me, if you're using a database and want to filter from the DB. Just build a query on each keypress to return the data valid for that search.

yes im using a database and the search result would appear to the gridview...im having a combobox that would give the textbox choices on which to filter...but i dont know how to use the like clause in the select statement propely..
sql = "Select Supplier_Information.Supplier_ID,Supplier_Information.Supplier_Name,Supplier_Information.Address,Supplier_Information.Contact_No, Products.Product_ID, Products.Product_Name,Products.Product_Type, Products.Present_Price, Products.Past_Price from Supplier_Information, Products where Supplier_Information.Supplier_ID like '%s-%' "
i have this code but it does not work properly...i want to come up with a textbox that would filter in every letter that they will type in the textbox.tnx

Whoah - this is a really bad design. Don't attempt to do this because you are going to be hitting the database after every keypress. The more users you have, the more you are going to hit the database. How would you handle the case where the user enters some text and then starts to delete text? Thats the same data being queried many times.
Please - rethink your design.

any suggestive design that i could make?may i know exacly what is the bad design that you are pertaining of...tnx

I'm sorry, but I thought I'd made myself clear enough. Don't design a system where you are hitting the database so many times. Apart from anything else, you probably won't be able to retrieve the data and display it quickly enough if the user is a quick typist.
As for the design - identify a more natural point for retrieving the data.

should i delete my combobox?or can i search any data on my database in my textbox without giving any choices for filtering
|

This has stopped being a question about databases and become a question about an autofiltering combo box. The exact details of how to do this depends on whether you are using Win Forms or ASP.NET.

VB.NET is a language. The question was about frameworks. Which framework are you using? The ASP.NET framework or the WinForms framework (both of which are part of the larger .NET Framework)
shyne7 wrote: hos to use the like clause for searching
WHERE SomeColumn LIKE '%'+@SomeSearchTerm+'%'
@SomeSearchTerm is passes as a parameter for security

u want to filter
so ,
u are writing the query. ok then in where clause
fieldname like '" & textbox1.text & "%'
u will get the result

NO NO NO NO!!!! Do NOT inject into SQL strings like this. I've been banging on about this for THREE years now! Doesn't anyone know about SQL Injection Attacks?!

Ah well - at least I did mention parameterized queries (albeit in another post) . Don't worry Colin - some of the more professional members of the site have read/taken in your message. Perhaps your technical test should include a query that's wide open for Sql Injection and then ask candidates if they can tell you what's wrong with it.

We believe we know the interval when multiple records are being entered when they shouldn't be (we don't know why yet, vendor to figure that out). The interval is something like 00:00:45 or so. Using managerial fuzzy logic, I can get better than superbly screwed up data by grouping the records by timestamp. This really seems like it lends itself to a cursor operation to first indicate whether the sorted records are in the proper date range, then we go by time and place a value into a new field to help us sort based on some fine subtraction caluculation. All in a job to automate it.
Anyone have a better suggestion? I'm pretty good with cursors and once it's run once, I can ignore existing rows to reduce the operation. It just seems so clumsy.
Thanks in advance,
i

Are the multiple records dups? This post needs more info what do mean by interval?
|
|
|
|
|
The "interval" is the time span during which dups were inserted in seconds. I though "interval" seemed appropriate. 
I've since found out that the multiple records are not dups. So there is no longer a need to do the record comparison and mark them in any way. We just need the vendor to answer a phone call so we can understand their model and eventually write a valid statement to aggregate all the related repair records by repair. (For example, an operator sees that a repair is needed, hits the button, automated machine repair happens, repair not effective, hits the button" should be 1 repair event, not 2).

any one remind me how to update,delete on asp.net based on given txtfield?
e.g we write code like this in oracle:
--update code:
update EMP set f_name=:txt_name
where id=:txt_id;
commit;
---delete code:
delete from EMP
where id=:txt_id;
commit;

Best way to do this is through parameterized queries. See this[^] article for advice.
Obviously, you will want to use the Oracle .Net providers.

imports system.data.sqlclient
dim objsqlconn as sqlconnection
dim objsqlcmd as sqlcommand
dim dataset as dataset
dim strupdate as string
first update
objsqlconn=new sqlconnection("user id=sa;password=;initial catalog=databasename;data source=servername")
objsqlconn.open
strupdate="update EMP set f_name=:txt_name where id=:txt_id"
objsqlcmd=new sqlcommand(strupdate,objsqlconn)
objsqlcmd.executenonquery()
messagebox.show("Record successfully update")
second delete
objsqlconn=new sqlconnection("user id=sa;password=;initial catalog=databasename;data source=servername")
objsqlconn.open
strdelete="delete from EMP where id=:txt_id"
objsqlcmd=new sqlcommand(strdelete,objsqlconn)
objsqlcmd.executenonquery()
messagebox.show("Record successfully delete")

How do you think this will work? First of all, you are connecting to SQL Server here, secondly the strupdate command is wrong. Finally, always use parameterized queries as they are much better.

Months don't have weeks, years have weeks. At least that seems to be what ISO says.
