We have a web service that is growing large enough that we wish to seperate logic. Ideally, we would have multiple code files on the server, and the service itself would still appear to be the same to consumers of it.
If we were doing it in c++, we would simply split the implementation of our WebService class across several .cpp. Of course, we can't do that in C#.
Any ideas or pointers to docs?

Well, in VS2005/C#2.0 you have partial classes if thats what you mean (spreading the implimentation across files). But I don't see why you couldn't just have the webservice methods call methods in other classes.

Another part of it is wanting to group methods by thier function; e.g. multiple webservices in one. So from the WSDL, you'd have
Service1<br />
{ <br />
func1();<br />
func2();<br />
}<br />
<br />
Service2<br />
{<br />
func1();<br />
func2();<br />
}
Your information about 2005 helps though - that may end up being our solution.

What do you mean "large enough"? Is it too large to maintain on the server or is it too large for any client to handle? Any good enterprise application has multiple layers of implementation to facilitate stuff like this. The exposed web service is just another layer in the API so nothing says it needs to needs to match any actual implementation details. You may have 100 objects that that are needed to make the web service "http://server/service" function but changing any one of them shouldn't change the service definition itself. You should be able to modify any of the 100 objects and not have to modify the interface for the web service. If this isn't happening now then you should rethink about the design. Although partial may help, your team should really be asking themselves do they really need a gigantic object so large it needs to span multiple files?
|
|
|
|
|
Most of the logic is in other objects. It's just that this particular .asmx is going to end up being huge and it becomes a pain in the rear to deal with - to add a new function or hunt another down.
|
|
|
|
|
Your team should be spliting the web service *anyway* into more managable functional groups. If you are lumping everything into one giant object then it is a poor design that will cause problems down the road because it will grow like a cancer. Changing one large object/web service is trickier than one small one in an API with hundreds of objects. Regression over one large object/web service is more costly than one of many small ones. Resources consumed for one large object/web service is more "brutal" than many small ones. So on and so forth...
Since it seems like a design issue there is no amount of coding or tricks that will help. The fact you are asking how to do break the object into multiple code files seems to indicate you know what is functionally disperate anyway. If you are already considering breaking up a large object into multiple files then why not break the object along those same functional lines?

I agree. The problem is I have not been expressing myself clearly.
What I want is multiple web services in the same .wsdl. (Like how MapPoints web service does it.) So the end user only has to know http://foobar/service/Product.asmx?wsdl; so they only need to configure one URL in thier application, rather than have 4 or 5 seperate web services, each with URL and proxy settings configured independantly.
 And before any tells me it's not possible, LOOK AT THE WSDL SPEC. Look at Mappoint! sheesh. [/end grouchy part]

I want to make a form, that I can draw a grid on it, any one have any ideas on this?
Thanks

Can you explian much more ?

sorry my pic is not the best

In the paint event of your form draw the lines you need using the graphics object in the paint event. I'd suggest using a loop to draw your horizontal and vertical lines.

I am trying to create a struct that I can dynamically add multiple elements to at runtime, but for some reason I just can’t grasp how to do this. In VB, I would create a User Defined Type as such:
<br />
Private Type Person<br />
fName As String<br />
lName As String<br />
age As Integer<br />
End Type<br />
And use like so:
<br />
Private Sub Command1_Click()<br />
Dim a As Integer<br />
<br />
a = 5<br />
ReDim x(a) As Crap <br />
<br />
<br />
For y = 0 To 4<br />
x(y).fName = "first" & y<br />
x(y).lName = "last" & y<br />
x(y).age = y<br />
Next<br />
But for some reason I just can’t seem to accomplish this in C#. Can someone please explain this process to me?
|

You are looking for an array of structs. Something like
struct Person
{
public string fName;
public string lName;
public int age;
}
void Command1_Click()
{
Person []persons = new Person[5];
for (int i = 0; i<5; ++i)
{
persons[i].fName = "first" + i.ToString();
persons[i].lName = "last" + i.ToString();
persons[i].Age = i;
}
}
BTW, it's recommended to use Properties[^] instead of public variables in structs and classes.

Thanks, that is exactly what I was attempting to accomplish. I will also follow the advice on properties as well.
|
|
|
|
|
What if you wanted to pass the struct as a parameter to method in a different object? Would a struct be the best solution, or is there a better way to that?
|
|
|
|
|
Depends on what your struct contains. If you want value semantics, that is, if you want to pass around a copy of your data everywhere, you can use a struct, otherwise, you can use a class. This[^] might help you decide which one to use.

My project will be accessing production data off of a *nix box via samba. When the data path is pointing to a local test dataset, or a test set on a remote windows machine everything works fine. But when I change the path to point at a folder on a linuxbox made accessable via samba the application doesn't update.

From Googling around on this subject, it appears that there are major problems with getting this to work. It doesn't look like there is a great amount of support. About the only thing I could suggest is upgrading the Samba server to the latest and see what happens.

Bleh. Easier said than done on the client end unfortunately.

Hello everyone,
I'm trying to 'log' Terminal Server activity. From a fileserver I want to access the Security-logs from the Terminal Server. In those logs we can retrieve log-in and log-out date and times including username.
Offcourse, I did some research... but after a couple of hours i gave up... can't find anything usefull.
<br />
<br />
EventLog elog = new EventLog("test","172.16.2.18");<br />
elog.Log = "Security";<br />
<br />
string one = elog.Entries[i].MachineName;<br />
string two = elog.Entries[i].index;<br />
string etc. etc.<br />
<br />
During my search for the truth out there  I came across these classes:
System.Security.Permissions.RegistryPermission
..and..
System.Security.Permissions.SecurityPermission
only I don't know how to apply these classes. Can anyone give me a codesnippet/example?
Thnx in advance!

Hey
I want to print a menu out of a listview.
I am using drawing lines using drawline method, but I am using a string[] to get the text being printed (using drawstring), the thing is that I do not know how to tell the string to start and ending printing inside a defined border. I mean, how do I give the string a maximum pixel and a minimum pixel to create a border?
thanks!
