You have to expose them as COM objects and register the assembly on the system with regasm.exe. If you need to access the Excel object model from these controls, you should also create and reference the Microsoft.Office.Interop.Excel.dll primary interop assembly (PIA), downloadable from http://msdn.microsoft.com/downloads/list/office.asp[^]. You can pass objects from Excel to your controls through methods you define, such as passing the Excel.Application object, which is what Excel does to foster automation with VBA (Visual Basic for Applications).
For more information create COM-Callable Wrappers (CCWs), see Nick's article at http://www.codeproject.com/dotnet/nettocom.asp[^].

I have created a Webservice using Visual Studio .NET 2003. The webservice works fine on my local webserver. I then created a Web Setup project to install/uninstall this webservice. I have tested it on my local machine and everything works fine.
Now, I need to deploy this webservice on my website. The ISP I use supports .NET Hosting v1.0/V1.1. However, how can I run the Web Setup on their server!???
I tried copying the files, but it doesn't work. I changed custom errors mode to be Off, and changed the authorization mode to None. I also changed the .webinfo file to reflect the webservice location.
Any ideas, how this can be done?

When I use the browser and type:
http://www.example.com/dotNet/MyService/Service1.asmx
I get the following (even when I set the customErrors mode to Off, I still get the same error:
Server Error in '/' Application.
--------------------------------------------------------------------------------
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

You can copy file there through ftp but don't forget that you have to put it in virtual folder , they have to create it for you or give you some admin privilage to do that. I'm not sure you can run installshield there when you don't have direct access to server. For my web service I copy files in the root of my web site(bin directory_config and asmx files) cause those stupids didn't let me to create virtual directory there.

What is the difference between having it in the root of the website vs. in a sub-directory? I thought virtual directories are to map internal server paths into sub-folders of wwwroot. In my case, I copied the files to a sub-folder of wwwroot. I attempt to execute the webservice as follows:
http://www.example.com/dotNet/MyService/Service1.asmx
which is similar to how I run it on my local machine:
http://localhost/Service1.asmx
Thanks,
Victor

When you create a web service with VS.NET it automaticlly do the setting for you and set that directory as virtual directory so it works without problem, but when you upload your files you have to do setting manually.

Makes sense... But what is the benefit of having it as a virtual directory? As I said before, I thought virtual directories are useful to map paths that are not under wwwroot to virtual directories under wwwroot.
Thanks for your help..

Victor.

Hi!
First of all, I'd like to excuse my stupid question  .
However, I'm having probelms understanding the use of simple lookup tables in c#. I do not want to use database to create them, but classes or data structures instead. How can it be accomplished? I'd appreciate if one could explain the idea and the usage thoroughly.
Little more about my problem. I'm implementing an price collection software that fetches prices from multiple web sites. So one item (lets say MS Windows XP professional) may have multiple prices and it's name may me written in multiple ways (such as Win XP Pro or Microsoft Windows XP Professional etc).
Any tips how to overcome this problem? Thanks you for your answers in advance!

I think the proper way is add a LIKE operation to your query string:
SELECT * FROM mytable WHERE product LIKE 'WIN%'
Or something like this query , I think most web sites use this mechanism. This would gain most of result correctlty.

Thanks for your quick response. However, I don't want to use database but classes instead. Any good tips to overcome it?

What do you mean exactlyy by not using database? You mean you want it disconnected from DB? So you can use DataSet and its Find() method when you after filling dataset.

Besides maintaining an instance of a DataSet (which can be easily serialized to and deserialized from XML) and using Find, you can also use an IDictionary implementation like the Hashtable. This won't, however, allows you to find similar but different names without extending the Hashtable greatly.
Otherwise, you can always build your own database-like implementation with lists, collections, and the sort. To find similar names you'll offen experience O(n) operations unless you use something like a character-based or word-fragment-based B-tree.
Another option is to go with an in-memory database that exhibits the ACID properties (although it goes about transaction processing differently) known as Bamboo Prevalence (a .NET version of Prevayler, which is a Java implementation). See http://bbooprevalence.sourceforge.net/[^] for more information, or Object Prevalence with Bamboo Prevalence[^] for an article about it here on CodeProject.

Hi!
I've written a Client-Server-Application using Remoting. The Server runs as a WindowsService on a Windows 2003 or Windows 2000 Server. So far everything is working fine.
But if the Server has 2 or even more Network-Cards installed - how do I tell my RemotingApplication which one to use? and 2nd: how do I get the IP-Address of each Network-Card?
Any help would be really appreciated!

You just have to specify the appropriate port. Windows device manager will internally map the port to one of the multiple network cards.
|
|
|
|
|
I already got that port-thing - my question was if I can tell the Framework/App explicitly which Network-Card to use?
anyway thanks for your answer!

After digging through the assemblies and documentation, if there is a way I haven't found it.
However, hiding information is by no means a way to secure information. Instead of worry about others getting your service definition, use the Web Services Enhancements 1.0[^] (2.0 is still a preview and shouldn't be used / can't be used due to licensing restrictions in production environments).
You can add WS-Security (remember my XML Digital Signatures article? That's a part of it) and many other things (like authentication via X.509 certificates) to ensure that no matter who gets your WSDL, only people to whom you grant credentials or certificates (or both) can access your Web Service.
This is by far a better way than just hiding it. If someone wants your service definition that badly, they will get it.

Just day dreaming here. But how can you dial to a phone using modem/C#/.NET, then play a clip, say in mp3 format?

The simplest way would be to use the TAPI 3 COM objects via COM Interop. Have a read on MSDN for the Tapi 3 docs. It should at least get you a starting point of making the call.
Not sure about playing mp3 down the phone though, I've only ever done that with Tapi 2 and Wav files via the Windows multimedia libraries.

That's incorrect - the .NET Framework is not supported on Windows 95.

.NET Remoting is your answer. This is the de facto way of marshaling and transmitting data between two different AppDomains. See Accessing Objects in Other Application Domains Using .NET Remoting[^] for topics and examples. Also visit http://www.ingorammer.com[^] for arguably one of the best sources for .NET Remoting information. He also has a book.
And speaking of books, there's also Microsoft .NET Remoting[^] from the Microsoft Press. It's a good intro and intermediate book on .NET Remoting.
You can also search the CodeProject site for information on .NET Remoting as well.
