Does anyone have any idea how to separate GUI and business/data logic by placing the GUI on a Web Server and the business/data logic on an App Server?
The only thing I can think of is to place a web service on the App Server which makes it a web server now but on the inside of a firewall and then having it make the calls to the already written DLLs, is there a better way?
-- Update - I just found out about .NET Remoting but that would not work in this case because some pieces of the overall application are VB6.
Thanks!

I think you could still use .NET Remoting, if your VB6 code was compiled as COM objects. You could write a .NET wrapper object that uses P/Invoke to execute the COM code. Then you could use .NET Remoting to communicate among the pieces.

Well in this case there are multiple web sites that interact with each other, an intranet site and an internet site. The intranet site is ASP 1.0 VB6 and the internet site is ASP.NET 2.0 VB.NET. The code that resides on the application server will be invoked by either of the web sites so Im not sure that .NET Remoting is an option in this case without doing excessive work on the VB6 site or am I wrong in assuming that?.

I do think .NET Remoting would be an option in your case. You'll want to look into COM Interop in addition to .NET Remoting; COM Interop allows your .NET code to be executed from a COM object (e.g. VB6). There's lots of articles on this - use Google to look for "COM Interop", "VB6 .NET Remoting", and the like.

Hi all.
I am wondering what you all think about this design issue. I have a page where a few things are static and one part, essentially another page, of it will be inserted when a choice is made in a combo box. The inserted portions contain static controls(text boxs, labels, drop down, etc...). I've seen this done on other websites but can't find any tutorials on how to do this. So I've thought of a couple of ways to go forward. One, I can create a user control for each inserted item, which there could be 10+ of, and register all of them on the page. Two, I can create classes which inherit from Panel for each item, programmatically add in each field into the panel at construction of the class. In either case, it could be pasted/created in when needed (on selection in the combo box).
I would prefer the user control route but I'm not sure about the impact on performance of registering 10+ controls on a page will have. The class route will be more tinkering.
I'd love to hear any kind of input on this. A link to a tutorial on how to do it would be good too.

There isn't a major performance issue with User Controls. If I understand your question, you are talking about dynamically loading UCs.

Ahh yes...it's all about the vocab. *sigh* I'll do some more searching. In fact, I already found some good things...hopefully. Thanks.

Hi ,
I have to upload .csv file data to oracle 10g database from asp.net 2.0 page.
As .csv file data are too much large (around 200,000 records) so decided to
insert it using Sqlloader utility of oracle.
Now to execute sqlloader utility from asp.net web page
i have to use .Bat file(Batch file) and where .bat file will take oracle database
connection and in first parameter as .csv file.
Now i don't know how to take database connection to oracle from .bat file??
even i don't know is it possible or not ??
if it's not possible then what should be the alternative way to take database connection
with oracle from .bat file??
Is any article /sample code /link then will be good for me.
Thanks in advance.

You can invoke a VBS from within a BATCH file which can use ADO right?

Hey guys, I'm trying to create a web-form (or website kind of thing) which returns xml when an url was called. I don't want to return html whatsoever, just as if an xml document url was called. How can I accomplish that?

Response.ContentType="text/xml"
From memory - not sure if MIME should be application/xml instead.
edit: oh yea, and Response.Write your xml then.

Seems to be working even without the Response.ContentType, but I guess using the content type would be neater.
Thanks!
|

Using the correct content type would provide hints to the client app that XML is about to be received. Internet Explorer (and probably most web browsers) are smart enough to distinguish XML even without this hint.

You're correct. text/xml is the right MIME type.

Hey Man,
Use repective Data Class. If you are using SQL Server Data.SQLClient Namespace... You don't know ADO.NET? You have posted three time with the same question to my knowledge.

GridView.DataSource = null;
GridView.DataBind();
There may also be other ways.
