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.

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); ?

Dave,
I tried but the namespace doesn´t exists....
I´m using VisualStudio 2003!!!
I think I can´t avoid shell....

Yes, it does exists, and has since .NET 1.0.
What does your code look like??

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.
|
|
|
|
|
Yeah! That´s where I´m placing the method executeFile. I´ll call by an event like listView_Click or eiter the listView_SelectedIndex
The code to populate I found here at CP and with a few changes I made it point to an expecific folder to be the root (just basic programming and basic O.O. concepts). My professors at college helped me a little because they are not quite familiar with .NET Framework. Even I got more familiarity with Assemble Languages and Structured C/Pascal... and few notions of O.O C++ and Objective C(Mac) (I HATE JAVA). I´m still junior in .NET but I´m trying!!!! I almost did it... just a few errors!!!
I appreciate all the help!!! I owe you guys a beer!!!!
Thanks

I have Visual Studio 2005 with Framework 2.0 installed in my machine. Can I use Framework 3.0 or 3.5 with Vistual Studio 2005. Or do you think that I need to have Visual Studio 2008 to work with 3.0 and 3.5. And also is Framework 3.5 is out or is that still in its Beta version.
Thanks

thanks for answering. i am scared upgrading from 2.0 or 3.5 in my existing vs 2005 as it may corrupt something. do you think this possibility. Why microsoft is releasing their framwork so often. It's getting very tough to catch up and live up the with one framwork atleast for a while.

3.0 and 3.5 live in addition to 2.0 so you can still use 2.0 if you like. In fact, VS2008 gives you the option of which of these frameworks you'd like to use on the New Project screen.
If you go for it you'll be able to play with LINQ, extension methods, WPF etc... That's why they added the new frameworks - new stuff/toys to play with

It is possible but unlikely. That's what backups are for.
2005 to 2008 upgrade is a lot easier than 2003 to 2005 especially as VS2008 supports multi-targetting. That means that in VS2008 you can specify what version of the .NET Framework you want to use in your project.
netJP12L wrote: Why microsoft is releasing their framwork so often.
Jeez, if you think that is bad you should have been around when MFC was at its height (late 90s). MS were releasing a new version of that every few months at one point.
.NET 3.0 and 3.5 are purely additive. In otherwords they don't make changes to bits released in previous versions. (Unlike 1.1 to 2.0)
That means that if you know .NET 2.0 then you are not required to learn anything new unless you want to.
netJP12L wrote: It's getting very tough to catch up and live up the with one framwork atleast for a while.
Then concentrate on the areas you will find useful. I try and take a high level view of everything so I know what is out there. Then I drill down into what I need when I need it. I find that I can ramp up to a new part of the framework fairly quickly because I already know what it is for and what it does, I just need to learn the detail.
