Hi Karthik,
I'm not sure I fully understand. Is it that you want to upload a text file, and using information in that text file you want to search the Access database?
quote:
pertaining to four column in the database
I don't understand this bit - why do you mention 4 columns here if your database is 2 columns?

Why an upload? Are you going to do something with the uploaded file other than search? Perhaps you can explain a little more in depth.

RE: search database with the text file uploaded - 12/15/2005 8:40:47
Hi,
i need to search the data in database using the text file.
i give an example here.
The following are the fields in database with values.
product price
--------- -----
soap 12
shampoo 13
i need to search the prices for both soap and shampoo
from single input. i cant do it through input in a textbox
so i decided to have a text file wherein i have the following
format:
product
---------
soap
shampoo
so i need to upload the text file which will search with the values in database(access) and return the results in the screen.
i need to search different multiple products rather a single product.
i hope it makes clear.
plz help me .
thanks in advance

Okey Dokey.
To grab things from a text document you will need to "parse" the document. The best way to parse text is to use Regular Expressions - though they aren't always easy to use. Here is an article on using RegExp with VBScript.
quote:
i cant do it through input in a textbox
Is there any reason for the "can't" ??? Perhaps you could get users to pass the values in a query string - tell them to go to yourpage.asp?product= and add the name of the product, so they put in their address bar yourpage.asp?product=shampoo. Then you can grab the value using the Response object.

RE: search database with the text file uploaded - 12/15/2005 13:49:48
you can still use a querystring, the user would type in
yourform.asp?product=shampoo&product=soap
and the following code would output it to the screen.
<%
For i = 1 To Request.QueryString("Q").Count
Response.Write Request.QueryString("Q")(i) & "<br />"
Next
%>
obviously you would do something different to the Response.write. Perhaps put it into another array and do something with that, or
<%
For i = 1 To Request.QueryString("Q").Count
mySQL = "SELECT * FROM Products WHERE ProductId = " & Request.QueryString("Q")(i) & ";"
Next
cmd.Execute(mySQL)
%>
Something like that.

why would the user have to type all that in? why not a drop down and the GET method?

RE: search database with the text file uploaded - 12/15/2005 14:12:59
I'd use a page with a list of all the products and a checkbox for each. Tick the box and submit and you get prices.
But if you were going to do that you could just put the price of the items on that page too.
What's the purpose of the site and who will be using the search output?

RE: search database with the text file uploaded - 12/15/2005 15:01:04
as I said, the only way I can think of to choose from 21000 products in an effective (ie quick) way is to use Ajax. If you have the option of .NET I can help build a page that does this. Otherwise, perhaps a checkboxlist and an alphabet as links to the first letter of what it is you want to pick.
Unless anyone else has a good idea?
What are you using for this, ASP? And do you know what version of IIS you are using? (if you are)

Karthik, if you could email me I'll send you back the compiled code and some instructions.
For the really geeky among you (that means everyone! ) here is the code. I didn't come up with the ajax part, I got that from the Code Project, so here's the code to implement it.
This is the web page

Set compilation debug="true" to enable ASPX debugging. Otherwise, setting this value to
false will improve runtime performance of this application.
Set compilation debug="true" to insert debugging symbols (.pdb information)
into the compiled page. Because this creates a larger file that executes
more slowly, you should set this value to true only when debugging and to
false at all other times. For more information, refer to the documentation about
debugging ASP.NET files.
-->

<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.
"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to users not running
on the local Web server. This setting is recommended for security purposes, so
that you do not display application detail information to remote clients.

<!-- AUTHENTICATION
This section sets the authentication policies of the application. Possible modes are "Windows",
"Forms", "Passport" and "None"
"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or Integrated Windows) according to
its settings for the application. Anonymous access must be disabled in IIS.
"Forms" You provide a custom form (Web page) for users to enter their credentials, and then
you authenticate them in your application. A user credential token is stored in a cookie.
"Passport" Authentication is performed via a centralized authentication service provided
by Microsoft that offers a single logon and core profile services for member sites.
-->
<authentication mode="Windows" />
<!-- AUTHORIZATION
This section sets the authorization policies of the application. You can allow or deny access
to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous

<!-- APPLICATION-LEVEL TRACE LOGGING
Application-level tracing enables trace log output for every page within an application.
Set trace enabled="true" to enable application trace logging. If pageOutput="true", the
trace information will be displayed at the bottom of each page. Otherwise, you can view the
application trace log by browsing the "trace.axd" page from your web application
root.

RE: search database with the text file uploaded - 12/16/2005 18:30:28
I've sent you the files and instructions, but here's some general ones.
.NET uses pre-compiled code, you can't just put the code into a page and run it without the dll's.
If you don't have something like Visual Studio, then download the .NET SDK. Then you can use the command line compiler to compile the code. Type into the compiler csc NameOfFileToCompile.cs and press enter.
Take the dll that has been compiled and put it in a dir called Bin that is in the main website dir. Also put the web.config into the directory - it holds useful settings, like the .dat files you used to get pre Win2000.
You'll also need to get the code from the link I gave, and put the javascripts either directly in the page or in a dir called Scripts off of the main dir.
If anyone else needs the dlls jsut let me know.
