I have a wmi enumerator, and I'm looking to build one for exchange wmi commands and I can't seem to get it to work. Below is my code.
As some background as to why, I am trying to query some things in exchange 2007 that are not stored in the registry and that I think are in the exchange database. An example of values I'm looking for are owa (Default Web Site) Properties inside of the EMC under server config --> client access --> owa (Default Web Site) Properties and the tabs underneath there.
Thanks for reading!
private void wmiExchangeEnumerator(string wmiSearchClass)
{
try
{
ManagementScope scope = null;
ManagementObjectSearcher searcher = null;
ConnectionOptions options = new ConnectionOptions();
if (textBox4.Text != "")
{
string serverName = textBox4.Text;
scope = new ManagementScope(GetStandardPath(serverName), options);
scope.Path = new ManagementPath(@"\\" + serverName + @"\root\MicrosoftExchangeV2");
scope.Options.Impersonation = ImpersonationLevel.Impersonate;
scope.Connect();
ObjectQuery query = new ObjectQuery("SELECT * FROM " + wmiSearchClass);
searcher = new ManagementObjectSearcher(scope, query);
}
else
{
scope = new ManagementScope();
scope.Path = new ManagementPath(@"\root\MicrosoftExchangeV2");
scope.Options.Impersonation = ImpersonationLevel.Impersonate;
scope.Connect();
searcher = new ManagementObjectSearcher("SELECT * FROM " + wmiSearchClass);
}
ManagementObjectCollection results = searcher.Get();
textBox5.Text += ("There are " + results.Count + " items in " + wmiSearchClass) + System.Environment.NewLine;
int count = 0;
foreach (ManagementObject result in results)
{
textBox5.Text += ("=============== " + wmiSearchClass + "[" + count + "] ===============") + System.Environment.NewLine;
count++;
PropertyDataCollection pdc = result.Properties;
foreach (PropertyData pd in pdc)
{
string name = pd.Name;
object obj = pd.Value;
if (obj != null)
{
string[] sa = obj as string[];
if (sa != null)
{
string ss = string.Join("\";\"", sa);
textBox5.Text += ("SA " + count.ToString() + ": " + name + " = string[] = \"" + ss + "\"") + System.Environment.NewLine;
}
else
{
textBox5.Text += (count.ToString() + ": " + name + " = \"" + obj.ToString() + "\"") + System.Environment.NewLine;
}
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

I need to write a web related search Engine in C++ or C#. I am more comfortable in C++, but I would also like to master C#. My question, is there any clear advantage of doing in one than the other?
Thanks

One obvious advantage of course is that you will not learn C# if you do it in C++.
Of course there is also a difference between C++ and managed C++. But if you use the former then you are more likely to learn about nitty gritty details of network details.

Are you saying learning C# is a disadvantage?

C# is a more modern language, which produces more reliable code. It has a vast class library which reduces the amount of code you have to write. Development is faster in C#, and it will be a requirement for many jobs for the foreseeable future.
You should take an opportunity to learn it.

Based on that everyone should immediately move to F#.

Only way to produced significantly more reliable code is to actually write code that is reliable. Language choice doesn't lead to success at that. People make the difference.

Pretty sure C++ has a vast number of libraries to access. They just don't come with the language.

Again people make the difference.

Which is true for C++.
In terms of employability if one knows C++ or C# and then learns SQL is probably going to have more opportunities, overall, than if one just learns another OO language.

"Based on that everyone should immediately move to F#."
Its a factor; not an absolute. You don't drive a Model T, do you?
"Only way to produced significantly more reliable code is to actually write code that is reliable. Language choice doesn't lead to success at that. People make the difference."
Have to disagree here; it's much less likely to have certain types of errors in C#, such as undetected buffer overruns. If the only factor is people, why is development in assembly language so slow? The tools you use make a big difference.
"Pretty sure C++ has a vast number of libraries to access. They just don't come with the language."
Locating and integrating them increases the amount of work you have to do to get a solution. There's no guarantee of mutual compatibility or any minimum level of reliability with a library from an unknown source. Then there's the versioning problem that's greatly reduced when all the libraries are integrated with the language release.
I think use of C# will increase, while use of C++ will decrease in the coming years. C# is a better bet at this point, in my opinion.

Got to love those analogies...
Exactly how many deliveries on a daily basis do you see via Model T?
What percentage from all mechanics will work on them?
How many auto parts stores sell parts for them?
In comparison the following study, which has been going on for years, and of which has the best methodology that I have ever seen demonstrates that C# certainly isn't one that you want to bet on for being the most popular in the near future.

Are you claiming that Assembly is comparable to C++?
And having programmed in C++ for many years the last time I had a pointer error was before there was an ANSI standard. You are aware that there are now and have been for many years (again before ANSI C++) tools which are very effective at discovering pointer errors?
Alan Balkany wrote: Locating and integrating them increases the amount of work you have to do to get a solution.
Huh?
Are you suggesting that C++ programmers don't know how to use google?
Or that there are not libraries that are very effective which do not come with the standard .Net API? As an example do you use a logging library? For that matter have you ever used the Enterprise library or any of number of other libraries from Microsoft which do not come with the .Net API?
Alan Balkany wrote: There's no guarantee of mutual compatibility or any minimum level of reliability with a library from an unknown source.
Presumably you mean in comparison with .Net API? Are you claiming you haven't found bugs in that? Or at least very odd things? I certainly have.
One advantage to other solutions is that there is at least a chance that I some how I can get a solution in the near future. For example I might be able to get the source code (free or at a reasonable price) and fix it myself. Or I might point out the problem to a 3rd party vendor and have a fix in a very short time (point of fact I have had that happen.) Conversely the only way I expect to have that happen with the .Net API is if a give a very large sum of money to Microsoft. (To be fair that would be exactly the same situation with Oracle as well.)
Alan Balkany wrote: Then there's the versioning problem that's greatly reduced when all the libraries are integrated with the language release.
No idea what you are talking about. If I compile with a C++ compiler with the standard C++ libraries then those libraries go in my install. If I update then so do the libraries.
Best I can suppose is that you are referring to the versioning problem that some people experienced across all Microsoft languages when they were not careful in the past. That however, as per my point about people, is caused because people (not languages) didn't know what they were doing.
Alan Balkany wrote: I think use of C# will increase, while use of C++ will decrease in the coming years. C# is a better bet at this point, in my opinion.
Actual statistics suggest otherwise. If you want to make that bet then Objective-C is much, much more likely to be the winner.

Could be.
For example
- Using TCP in C++ will require learning more about that versus C#.
- One is more likely to learn about how the OS manages memory if one uses C++.
- One is more likely to learn about how the OS manages other types of resources if one uses C++.
Doesn't mean that one will not learn those with C# but rather that it is more likely that with C++ will need to learn about those in detail.

Hello
I am calling a piece of code in all my aspx.cs pages, which is like an error trapping class.
Can I create an actual class, and then include this class in my aspx.cs pages, so if I do have a change I can make this change in one place, in this one class instead of all my aspx.cs pages?
How would I go to call this class?
I was able to create a stand alone class but how to include in my aspx.cs pages?
Thanks!

Inheritance will solve your problem. You create a base page based on the built-in Page object:
public abstract class MyPageBase : System.Web.UI.Page {
}
Then in your codebehind files, you can inherit from the class:
public partial class DefaultPage : MyPageBase {
}

If you are really trying to implent a top-level exception handler to trap all errors,
you might like to use the Application_Error method in Global.asax. There is an whole knowledge base article about it here[^]. This has the added advantage of trapping some extra [mostly unlikely] errors.
In all other cases Matt Meyer's answer is excellent.
[Edit]
Replaced bizzare language with a more commonly used one called English, and changed the content so it says what I mean rather than simply meaining what I say. </Idiotness>

I have 2 list collections as below
List1
115
100
150
List2
115
100
now i need to check both of above list and need to get answer for matched ,
for example :
115
100
both matched, i need to achieve this how can i do it ?

C# 3.5? list1.Intersect(list2)[^] (it's an extension method in System.Linq)
If not, it's trivial to produce a naive implementation which will be fine for small lists:
IList<T> Intersection<T>(ICollection<T> one, ICollection<T> two){
IList<T> r = new List<T>();
foreach(T t in one)
if(two.Contains(t)) r.Add(t);
return r;
}

You've been around long enough to know and understand the forum guidelines. DON'T REPOST. You asked this same question four hours ago in the C# forum, it has nothing to do with ASP.NET. If you didn't receive an answer, wait. Don't repost.

I think he should delete the other one, not this one, though. C# forum is the correct place for it, the other one is misplaced (and I didn't see it there since I don't read the ASP.NET forum  ).

Consider using HashSet instead.

I would be willing to be that you need to update your .net install.

I've looked all over the internet for a formula to calculate the start angle and end angle of an arc. It's very awkward since the angles go in a clockwise motion. The parameters I have are, (X1, Y1), (X2, Y2), ArcCenter, Radius. I'm pretty sure the calculation uses Atan2 as I have tried to figure it out myself.
Thanks
