You don't put the progress bar in the background thread. It MUST stay on the UI (startup) thread. Your work goes in the background thread and then Invokes a method that updates the progress bar on the UI thread.

I'm in my third year of a software development course and will soon be tasked with completing a project to demonstrate my knowledge so far in programming.
I have decided to pick c# as the language as I'm more confident with it and my ideas so far are either a website with a database and/or a shopping cart or else an application like a movie library that has a database and capabilities to update info from the web.
The spec for the project is vague in terms of features and functions as I'm just going by what I've learned in the last three years.
I would be grateful if anyone could give me some feedback on my ideas or any new ideas they may have.
Thanks for your time

Depending on how long you have....
C# and unity go nice together..

Choose something that you have an interest in, so that your knowledge can help you design the program. It is impossible to suggest much more as we have no idea of your experience. You could look at the CodeProject Articles section[^] for some further ideas.

Go with Richards idea, my son did his on scuba diving, his hobby at the time.
If you can't think of something then try and find a friend who runs a small business and ask then for their most painful paperwork job then try and automate it. Beware you may lose that friend, birthing your first LOB solution is a painful exercise for all involved.

Hi johnmolo,
You can chose any one of the projects you mentioned.But take care of following points.
1.Use coding standards.
2.You should include all the OOPs concept in your project.
3.Database standards should be followed.
4.Use MVC architecture for designing.
5.Choose a professional looking design, no need for a complex design.
6.Try not to use any external API's since it may cause problem at any time.
Happy coding and wish you all the best for your project

What if someone would like to do payment integration. External API is the only bridge that can help Software developers to work beyond the limit of their existing software. You can add more functionality and more features. My personal opinion is to use already build application (API) instead of rebuilding the same. If we have Image processing library why should i create my own for even my small project.
I am not against you but always there is two side of coin. You may have some bad experience with external API's.
Thanks

Hi Amit,
Thanks to point out the mistake.What i really meant was not to use complex APIs since it may affect working of project ( I had a bad experience ).

Why? One of the worst pieces of advice for someone is generally "use pattern x on this project" before the project requirements have been defined. You should never go into a project having picked patterns to follow because you end up constraining your design and you might have to contort it to fit an unsuitable architecture.

Agree, decision of architecture and design pattern is vary by project.
Thanks

Hi,
Sorry for the mistake.I defined this one since it was mostly used among Dot Net developer these days.I would like to take back this point.

It's used commonly by .NET web developers you mean. WPF and Silverlight developers tend to steer clear of it, Winforms developers will not have done much with it and server side developers will have steered clear of it.

There are many application in the market. if you do something different that people may not have seen before that may impact more. If you want to earn more credit compare to your other class friends you need to think beyond the usual application development. Your idea is not bad but you can find many opensource application in the market with the shopping cart or database applications.
I suggest you to work in any opensource community to provide them help to create some modules or may be some functionality. But first get approval from your project guide. Creating project from scratch is not the only option. First you need to identify any of the community and the functionality they are looking for.
Second option is to work on some algorithm that are not implemented in C#. You can also convert any existing C/C++ library and publish as an opensource. that will also gives you credit from many developers.
But the primary thing is to convince your project guide.
Thanks

I would go for the movie database. A webshop application can become very complex.
For extra credit I would create it more as a media library that can also contain books and CD's for example. (and then tie those together).
Also if you're allowed, create something like a flashy WPF (or winforms) instead of web. It removes the problems of sessions, client/server code etc...
Don't get me wrong, don't set the level too low, but my experience is that applications tend to be more complex than you imagined them to be, especially when you're still junior.
hope this helps.

My file contains data like:
First name: ahmed
Last name: nasser
City: giza
i created a flat file schema to parse this file, but the element store all the line.. such as
<Fname>First name: ahmed</Fname>
<Lname>Last name: nasser</Lname>
i want the element to store only the value without the label ..to be like this:
<Fname>ahmed</Fname>
<Lname>nasser</Lname>
How To do that using Flate File Schema.. BizTalk?

The script needs to visit a series of game retailer websites and input some keywords into their search boxes. Then it yields the product results sorted by price in an HTML table in a separate page. The resulting HTML table is a list of the accumulated results.
The goal is to obtain a sorted overview of the total result set, sorted by price so that the cheapest version of the game (lowest price) is visible on the top of the list.
How would I begin coding this?
Is another implementation language recommended (Javascript, AHK, Selenium, etc.)?

I am using c#.
I want to print bill of a shop which contains dynamic data.
currently i am converting it in pdf,saved it in a folder & then print it.
what i have to do so that i can directly prepare a bill format using c# and print it without saving & converting it into pdf.
I think i can use datagridview.
Is there any better option rather than using datagridview.

Look at using the PrintDocument class[^] - the link includes an example.
This message is manufactured from fully recyclable noughts and ones. To recycle this message, please separate into two tidy piles, and take them to your nearest local recycling centre.
Please note that in some areas noughts are always replaced with zeros by law, and many facilities cannot recycle zeroes - in this case, please bury them in your back garden and water frequently.

I want to write some trace messages to a text file. The same methods could be called in different places. So, if I have something like method A calls B calls C calls B calls E calls C calls D, E, F, I'd like my trace file to show an indentation like this (assume the full stop implies a space character):
A
.B
..C
...B
....E
.....C
......D
......E
......F
Edit: I forgot to mention there's no recursion and the calls to C might not even get called, that sort of thing.
So, method C is called in different places and I'd like to reflect the "depth" where its called from. An old trick is to have a global variable that you increment/decrement but that's really messy. It's not essential that I do what I'd like but it would make the trace file easier to read if things are indented. I know it's a daft question with a limited shelf-life but if anyone does know a quick trick that'd do it for me, I'd be happy to test it.
Tks.

I suppose you could mess around with StackTrace[^] and its FrameCount property. It requires no changes anywhere, but it's crazy slow.
|
|
|
|
|
It's doable, but not practical.
Every one of your methods that participates in this scheme would have to pass around a "depth" field. Every time a method that uses this field is called, it would have to pass the current depth to the next method, where one of the first things the callee does is increment the depth.
I'm not liking this as is neccessitates passing an extra value into each method and each method would have to be custom implemented to support this, possibly interfering with your logic, but certainly adding a bit more complexity and duplication in your code.
I don't see any other way to do this, but I could be wrong.
[EDIT]
I just thought of something. You might be able to use the StackTrace for the current depth in some logging component, but don't count on it being accurate as you'll also be counting depth into calls that do not belong to your code.

Thanks guys. I did some research and I did find some suggestions to use the stack frame count. I think I'll bail out from my indentation idea as performance, while negotiable to a degree, can't be degraded too much because idle-time interrupts in the device could kick in. A few are ok because there is some recovery and resending but I don't want to sail too close to shore. Thanks again for confirming my options.

I suggest you research logging APIs instead.
