Perhaps Crazy Idea for a Summer Project: Intelligent Book Library and Online Ordering System

I was thinking for some time to try and do some home automation by building a system to manage my library of physical books.

Basically I'm thinking on building a system that automatically retreives and stores books from a shelf based on user input. Add to that, I'm also thinking on building a system that could browse through Amazon and order books for me.

I can handle the first part but I have absolutely no idea how to approach the automatic book ordering system. Now, I can imagine a dozen reasons why Amazon wouldn't want people abusing their website but I would really like to come up with something that could just grab whatever book title I tell it to look for and just do the order for me.

Is this even possible? To be fair I don't have much experience in web programming, I'm more familiar with embedded systems, desktop apps and games so I'm not sure if its feasable to write something in C# to do this or if there's some kind of API provided by Amazon that would allow me to automate the ordering process.

I know I can use POST to tell the server to accept data but I don't know if something as simple as this would work in my case.
Heck, if its not possible for Amazon, any other decent place where I can order books from would be nice.

Google Site - SMTP support? ASP.NET? Microsoft SQL server?

"Google Site" - I understand it's free, but:
a. SMTP support?
b. Can it host ASP.NET? I suspect you can only post static HTML page?
c. Database support?
What about database support? Microsoft SQL server?

I read their page, doesn't seem there's any mention of SMTP[^]

I doubt it's possible.[^]

I don't think there's any server side scripting supported by Google Site: ""It is disturbing and unexpected that googlesites is not dynamic enough to allow other popular scripting and programming languages"[^]
Thanks

Google is a website. If you want to know what services (paid or free) they offer then try their help or contact them directly.

no.. "Google Site" is free hosting service (But apparently no server side scripting supported, and no SMTP)[^]

How to display a radiobuttonList along with a textbox with dynamically generated values?

Hi Gurus,

We have an online ballot app that has a bunch of radioButtonList with values dynamically populated from the database.

Please see screenshots below to see example ballot

Sample ballot

All values ( Candidate A, Candidate B, Write In Candidate) are all stored on the database dynamically populate the radioButtonList.

Example 1 shows the current setup.

How do I modify my script to have setup similar to example2?

Here is the code I am working with so far:

The object rb1 has not been initialised; use your debugger to diagnose why this happens.

`You can create a unit test[^]
Alternatively You can create a new project that has a very basic GUI and calls whatever you need to call.

Create a for loop and in each loop you can start a new thread[^] calling the method that will create a report.

Also read up on load testing[^]

hope this helps.

how to make dropdownlist select manually inserted value

Hi, have following situation:
Using a dropdownlist with sqldatasource as source for selectedvalue and objectdatasource as source for the listitems.
I have added 1 item to the dropdownlist in the aspx page. It doesn't show up on the page though. I'm guessing the databind clears the listitems, but where is the best place to put it then?
If I get a null value from the sqldatasource, I need to select the manually added item. If not, I need to select an item from the databound listitems. Of course, if the manually added item stays selected, I need to return that null value back to the sqldatasource for insert/update. Guessing that last part needs to be done in the inserting/updating eventhandler of the sqldatasource, but otherwise, I'm not really sure what to do.
Using the customized dropdownlist I got from the Microsoft website(Customized Dropdownlist), I have fixed the problem that an exception was thrown every time I tried to select the manually inserted item, but it doesn't show on the page.

Anyone care to help me out here?
Thanks.

Mixing Data binding and custom elements in a Dropdown is always an headache. If the Data source is a DataTable, you can add your manual entry into the table as a row before the data binding process. Add it as the first item and you can write custom logic to handle this special case based on the index of the item selected.

Figured out the problem: I had disabled the inserted item. Anyone know though if you can enforce the user to select a different item other than disabling it?

I have a chart control in my ASPX page. At the top of the page there are some dropdown boxes to select some parameters to draw chart control and a button. Initially the chart control is invisible. After the btton click the chart control databinding will be done and visible property is set true. How to make the Chart control to be focused where it is at the down of the page after button click. Where now after postback the user has to scroll down to view the chart.

If I remember correctly,

the button click event fires a postback to the server, the page is sent to the server
background processing occurs on the server, here you can toggle the visible property
the page is sent back to the client, and then the page loads again with new HTML
the page.load event fires again

so the focus should probably be in the page.load event,
if page.ispostback {
if yyy.visible = true {
xxx.focus
}
}

try that out.

Switching from PHP to ASP.NET

After working with C# for a few years now, i'm thinking about to switch my web development branch to .NET as well. But old habits die hard, and i find it very hard to do the switch. Especially considering the PHP codebase i leave behind.

So the question is, is there any good material, tips, guides, tutorials and so on, for an old PHP egghead like me?

At today's rapid pace of technological advancement, it is necessary to be versatile. Learning new technology does not have to be at the expense of abandoning an existing one as long as it is still relevant. Take it as an add-on, and the knowledge and experience that you have acquired for PHP should give an advantage as you would have understand how the web work and you would already have the competency in solving problem using code. It is only a matter of learning a new language and a new paradigm of coding, but one thing never change, that is your ability to solve problems using code (as you already have), albeit a different one.
To get started, try this: Learn About ASP.NET Web Forms[^]

I don't think i will abandon PHP anytime soon, but i will slowly, but surely shift over to ASP.NET. That's why i want to start as soon as possible to learn all the stuff that is required to produce a working web application, with the same quality standards i have for my PHP based applications.
