Yeah, I've done lots of that, but I do need to get to basics... (sorry, had to eat). But, some of it's just boring to go through, and then there's the cool stuff. Thanks a lot.

Does anyone have any other trusted lnks as to where a beginner should go?
|

Really, a beginner should buy a book and work through it. After that, once you have a handle on C# in general, and the 'boring' bits, you shouldn't need any other resources than MSDN and this site. There are also MSDN forums, but I think these forums are better. By MSDN, I mean msdn.microsoft.com, where all the C# documentation is.

Honestly, I've got several, but, MAN! Books alone are tough. I'm going to look into a class (no pun intended). Thanks!

Not sure if such a thing exists

Hi!
I think it could help if you read about the concepts of .NET, especially the CLR.
When you write a .NET program (be it C#, VB.NET, J#,...), it gets compiled to IL and a runtime has to interprete this IL.
This is similar to Java, but you have two completely different runtime environments: the JVM für Java, the .NET runtime for .NET.
You can install the .NET Compact Framework on mobile devices, though, and then run special .NET programs on these devices, too.
But they are and stay .NET programs and not Java applications!

Try a DatePicker or DateTimePicker instead.
|
|
|
|

If you don't want to use a picker, but want to start from some string information,
either use DateTime.TryParse to parse an entire date/time string, or use int.TryParse
to parse the numeric fields, then use the appropriate DateTime constructor.

Hi!
I am trying to create a simple example with the System.Timers.Timer, and i can not.
can someone show me where i need to declare in a win project this timer and how to use it(which event?how to declare it?)
I have searched the web but i get only complex examples and not the simple one, even in the MSDN.
Thanks

Hi,
the timer classes on MSDN contain a simple example.
I have an article on timers, it comes with some test/demo code.
The easiest timer to use (in a Windows app) is a Windows.Forms.Timer (not the System.
Timers.Timer since that one ticks on another thread).

Is it possible to specify the date and time of an outgoing System.Net.Mail.MailMessage?
|
|
|
|
|
The date/time to send the mail can ce stored in the property DeferredDeliveryTime. If DeferredDeliveryTime contains any value, the Exchange server will keep the mail in the outbox until the specified date/time.

I'v been making an app that communicates with my home pc from any other. One of the things it does is sends a message to my pc saying to delete a file or directory (and if its a file or directory its deleting)
Anyway, i tell it to delete a folder within My Documents (the folder was NOT empty, it had files and other folders within it)
So, my home pc calls
Directoty.Delete(path, true);
I have no idea what the hell happened, by all files and folders within my documents had been deleted. It should have come back with an exception because the folder was not empty right? How the hell did it get to the parent directory and start deleting everything?
|

|

Well, by passing a true to the Delete call, you are telling it to remove directories, subdirectories, and files in path. If you actually read the MSDN documentation on Directory.Delete(String, Boolean)[^], it says that an IOException will be thrown when dhe directory specified by path is read-only, or recursive is false and path is not an empty directory.
As to why it deleted starting at the wrong directory, how sure are you that the path you sent is actually the one that was received? Put some debugging statements in your client code and print out the path before actually performing the delete (or instead of it) to make sure it's working with the correct path.

I must have misread, i knew by using recursive it deleted subdirectories, but i thought they had to be empty of files.
But still, more care on my part in future, especially when dealing with delete()
|
|

|

It's easy to miss. You should always be careful when dealing with file or directory deletes. I worked with someone who managed to get a bug into production that under certain conditions would delete the entire C:\Users directory due to a bug in the recursion. (It was code that had been added and never code reviewed, but it shipped anyway and caused a huge headache.)

Sounds bad...
Just goes to show, code reviews can be a good thing :->

It was. It caused a lot of people to scramble to figure out ways to help the affected customers recover the deleted files. The worst part of it is that the developer is still at the company and didn't even get a reprimand.
Code reviews are always a good thing, but their effectiveness is limited by how seriously people take them.

Very true. It does depend on how serious people take it. Seems more that often there is a rush to get things out into production and play blame game later.

Take a BrainBench certification if that's all your interested in. Seriously, having a certification doesn't prove that you know programming. Experience and past accomplishments prove you know programming. All the certification does is show that you have knowledge of a particular language and programming concepts.
If you want one of the Microsoft certifications, go to the Microsoft Learning[^] pages and look at the different certifications you can earn. There are different ones depending on what your development focus is. This will give you all of the information you need to know which exams you need to take and were to get study materials.
Seriously, the certifications should be about what you know not how hard you can study.
