The code which I provided takes care SQL injection problems. You do it by writing parameterized queries. The using block in my code ensures resources are properly cleaned up.

Will take care ok ... however I have already attended a course of a year to become "web designer", only that the world of Internet is so broad, I starts now to understand how powerful ASP.NET compared to other languages.
Many people underestimate, but wrong, especially those who are in favor of open source like PHP and company! PHP is not very functional for me.

A small correction. ASP.NET is not a language. It is a framework which can be programmed using C# or VB.NET. C# and VB.NET are the languages.

just simply make a dataset and a datatable....

and use sqldataadapter instead of sqlcommand....

and fill the dataset using SqlDataAdapter.fill(Dataset ds, "<tablename>")

then make a datatable

DataTable dt = ds.Tables["<tablename>"];

then ur return statement...

Dear All,
I am using asp.net 3.5 with Microsoft Reporting Service (RDLC).

My Application works fine in local machine. But when I upload my application in my real application server it shows the following error message
My real application server is a shared asp.net 3.5 hosting provider.
Can anyone advice to resolve it.

I think this is the problem with Trust level.
The application requires Full / Medium trust level while you are running it in Low Trust level.

Open your web.config and add

<trust level="Medium" originUrl="" />

to your <system.web> section.

hello all
I have a question.
My website has fileupload control that everyone can send data as doc,jpg and etc. Now I want to know that when they upload their files, where were these files go? it means that the transferred files go to the internet and I should download them to access them or these files send to my computer directly and I shouldn't connect to internet to see uploaded files.

For example suppose that a person whose name is FIRST upload a word file(doc) for me in my site. now I want to access to it to read it. what should I do?

Should I connect to the server that I buy my host from it and download that file? or that file send to my hard drive directly and it's in my computer.

Does it have any relation to ftp? if it does please explain for me about ftp?

excuse me for low English and long text.

The file will save to your server on the path where you have mentioned in your code. I guess you used some thing like,

FileUpload1.SaveAs(filepath);
Where filepath is server path location. Make sure when you host the site on IIS, you need to give the proper persmission to that folder for giving user to write access permission. It will normally work from VS Studio as VC Intergrated ASP.NET Enginge having full rights to write on Local Disk, but when you will host on IIS you need to setup the permission.

change data value by one when I click on checkbox in gridview

Hi!

I have database of movies and if there is available movies, someone (member) can borow it. I need to keep track of how many more movies is available so when someone returns a movie I increase the number of available movies by one. I have a gridview of borowed movies and I can click on checkbox if some movie is returned. My question is how do I update database to increase number of available movies (for example Matrix) by one when I check "movie returned" checkbox in gridview? Is there some easy way? I also need to search through a movie database and display names and how many movies is available for each movie (I need to display it in gridview). I know how to search for a movie but don't know sql command that will display field of movie availability.

Yes, it's called SQL. This is a very simple SQL statement.

OK, so once you do the search, you need to do a join to whatever table tells you how many movies you have on hand, that's basically it. The specifics depend on the layout of the DB, but it's all still SQL 101.

Can you tell me this statement?
if checkbox is checked (movie returned) then number of available movies is increased by one
else number of available movies is decreased by one

How to wrote that in sql? Do I need to combine UPDATE and SELECT somehow?

I can't tell you the statement without seeing the db. But yes, you'd do a select to get the old value, add one and update the column to contain that value.

I have a problem. The debugger in VS1.1 is not hitting the breakpoint. I have correct configuration settings (set to Debug) under the Project Properties and also debug attribute is set to true in config file. When the application is built and the output is rendered in the browser the application gets detached and enven can be rebuilt and run again. Can any one guide me whats the issue?
Thanks in advance.

Do you have multiple framework version on your machine?

Follow the below instruction-

If Anonymous is on, then the app is running under the ASPNET account (or
possibly Network Service). These accounts (and add IUSR_ while you're
there) should also be in the Debuggers group.
Or
simply turn off Anonymous. If your web server is not your desktop, then try
turning on Basic. Then the application will be running under your user
context.

Where is your application hosted ? Is it hosted on IIS and you want to debug your code ? Then you need to attach process for debug.

How to read/write data from another website onto your webpage?

Goalie3526-Sep-09 12:22

Goalie35

26-Sep-09 12:22

Does anyone know of a .NET solution to reading data from another website and updating data on that website? For example, there's a fantasy sports website that can read & display data about a persons "Yahoo!" fantasy sports team and send updates back to Yahoo. They also do this for about 20 other fantasy sports websites.

As you can see in this image (http://97.74.54.51/images/image1.jpg), they ask for your Yahoo account info. They then somehow retrieve your Yahoo data and display it onto their page (http://97.74.54.51/images/image2.jpg).

Does anyone know how this can be done or what programming methods I should be looking into to do this?

Thanks.
