Sounds like it's going to be a bit tough if you haven't touched C# for 3 years. I'd recommend:
1. Learn to post in the correct forum. This one is for specific C# coding issues only. If you don't observe the basic site rules, people here will get fed up very quickly. It sounds like you may be asking for a lot of help very soon so you don't want that.
2. Dig out your C# books, get some new ones if needed and get reading.
3. Ask your employer (if you haven't already) what project(s) your going to be working on and do some research and experimental coding NOW on those subjects or you'll be unemployed very quickly.
4. If you can't handle it, be honest and quit so someone who's really qualified may get the job without having to clean up too much mess. This may not be neccesary - but if it is, do it.
[Edit] By the way, congratulations and good luck  [/Edit]

Hi,
Can I create a UserControl that can be used in WPF by using the Language Service Package comes with VS SDK ?
VSSDKInstallDir\VisualStudioIntegration\Tools\Babel
Thanks!

Yes, there is more than one sample that shows you how to do this.
xacc.ide - now with TabsToSpaces support IronScheme - 1.0 beta 1 - coming soon ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

Hmm, There are some samples for VS integration packages... But I couldn't find anything for creating usercontrol using this. If you know any link could you please send it to me?
Thanks!

I am not getting the connection here. How is creating/using a UserControl in WPF related to Language Services?

He is using the VS SDK. There are some sample that shows you to use .net controls for use inside VS. IIRC you can host a WPF control in a Winforms control.

I try to create a Windows Service which listens to UDP port 514, i install it using installutil.exe and i get the following error message:
---------------------------

The SyslogService2005 service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs.

What about attaching the debugger and stepping through the startup code?

Hello folks!!!
I have a serious problem. I´making a "file explorer" in C# and it has to set a root node from an external HDD and show only files and folders hierarchically down it. This I´ve done and it´s working "fine"... with some problems but working!
The major problem is that I´ve to load a file by double clicking it on the list view (DWGs MUST open with AutoCAD, DOCs and Spreadsheets MUST open with MS Ofiice, Pictures must open with paint and whatever!) I know that I need to use ShellAPI BUT I´m having problems to use it properlly... I´ve been reading some HotTo´s, articles, walkthroughs (including C# does Shell) but none answer my question especifically.....
Can some one please help me? I´m desperate!!!!
thanks
PS. I´m using framework 1.1/2.0 with .NET 2003

Do you have to use the shell? if so, there's a cool article on here somewhere if you search.
Any reason why you can't just use System.Diagnosics.Process.Start(pathToFile); ?

Yes, it does exists, and has since .NET 1.0.

Just ignore the comments in portuguese!! I translated some important lines to english!!!
If anyone could helpme I will be VERY pleased!!! very very very pleased!!! I will thank my whole life!!!!

NOT THE WHILE BLOODY THING!! Just the part where you're having the problem launching files!
Thankfully, that part is at the end of the file. Noone is going to go looking through all that code for a small part...
Your executeFile method just needs to do something like:
Process.Start(filepath)
Because the Shell interpret spaces as a delimiter, it's a good idea to enclose filepaths in double quotes.
Process.Start(String.Format("\"{0}\"", filepath))
|
|
|
|
|
hahahahahaha sorry for that, my mistake  !!!!
It was just if you wanted to to test it!!! So I showed the whole thing!!!!
Well, as you can see I´m bloody new on c# and .net!!! The other question is where I call the executeFile method???
but the complier is still yelling me that System.Diagnosics.Process namespace doesn´t exists!!!
There is something else I should do?
Thanks!!! I really appreciate the whole support you are giving me!!!

Oops - that might be because of a typo in my earlier post!
Diagnosics should be
Diagnostics (missed the 't')

hehehehehehehe no problem dude!!!!
just one last question... on the header of the code a put just
using System.Diagnostics; ??? because System.Diagnostic.Process is unrecognized too : /
Thank you dudes.. I really owe you one!!!!
|

In 'using's at the top of your file you can only put namespaces.
Process is a class within System.Diagnostics so it can't be put in the using (and of course Start is a method of that class).
For future reference, typos like that happen quite regularly. If something's not found there's several ways to find the error.
1. Type the line letter by letter until intellisense kicks in, and see if what you need is in the list (spelled correctly!).
2. Use the Object Browser and search for the class and/or method, or alternatively, browse from the base namespace. This can be good for finding out if there are any references you need to add to your project too.
3. Paste it into google, if there is a typo, at the top of the first page of search results there will normally be a suggested correct spelling.
The first two have the added benifit of showing you all the other stuff in that namespace/class that you wouldn't have known about otherwise. You can learn loads of new stuff by browsing around in there.

Then you just use Process, not System.Diagnostics.Process.
The using statement at the top frees you from haing to type the entire qualifier.
As for where you call the execute statement, that's up to your design! Though, having looked at the entire code you posted, you don't have any code doing anything with the files in the listview after the listview is populated. So, I have no idea what you expect the user to do to launch a file. What happens there is totally up to you.
