hello everybody,
in my web site i have two databases, ASPNETDB.MDF and a self created one (database.mdf). (The don't contain a lot of data yet) But i need a relationship (foreign key) between a table in ASPNETDB.MDF and a table in database.mdf.
So i guess i need to merge both databases first, would you just extend the "ASPNETDB.MDF" with the tables from "database.mdf" ? or better configure "database.mdf" for the asp.net Applicatoin Services and then delete "ASPNETDB.MDF" ? Is "ASPNETDB.MDF" even meant to be used in a production online web application?
(Right now i'm using sql server express but i will probably use sql server when deploying Site to a shared host)
thanks a lot for answers

Merge the two databases on One! and then make your relationship with tables.

Hi,
I am trying to bind a XML file to a grdiview and get an error:
The data source for GridView with id 'gvPhotos' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.
I found out that I have to make and xsl format to solve this issue. Here is the original XML file.
What's the correct XSL format for it ? Thanks for the time and effort.
<gallery>
<settings>
<imagesFolder>friedmans-admin/Photos/</imagesFolder>

Hi,
I've written a stream to minify HTML code and I want to make it run every time a response is completed.
To do this, I've created a module that registers this stream using the Response.Filter property.
The problem is that on some pages of my website, I get an ObjectDisposedException while writing in the base stream (the original value of Response.Filter).
Any solutions?
PS: the only difference between the "working" pages and the "not working" pages, is that the not working page contains a TabControl.
I hope the TabControl isn't the cause of this exception!

Hi,
I have this class:
[Serializable]
public class Item
{
public string ProdName { get; set; }
public string Qty { get; set; }
}
[Serializable]
public class Order
{
public DateTime Dt;
public int CustomerId;
public List<Item> Items;
}
It's implemented in a separated assembly and is used in a lot of projects (the class is bigger than it appears here)
When I made a webService to return a List<item>, I have two problems.
1) The WebReference I add in the client has a definition of Order that the compiler thinks it's not from the assembly they are defined into. I can't cast. I have to create a List<item> and populate with the data returned from the WebMethod. Worst, It doesn't return a List<>, it returns an [].
2) The Item.Items is not a member of this new (mirror) type the webservice declares?
Is there a way to fix it? At least the #2?
Thanks,
Dirso

Hi!
1) I see, i think it would work, but the other problems keep comming
2) Didn't work for me. The Items are a IList<item> I tried to XmlInclude Item, but it still doesn't seem to be exported
Thanks,
Dirso

This is correct (and good!) behaviour. The web service is supposed to be agnostic of the client (for example a Java client can consume a .Net web service and vice versa). This is the reason the list is returned as an array, as all languages have the concept of an array, but not a list. The same goes for the Order type not casting, the message passed between the client and server is just a "value bag" that looks like an object, you are supposed to populate proper objects from them when then response is recieved. When you generate the client, a new class type is created. The generated class will have a different namespace but normally the same name as the originating server type. This won't cast as it is a completely different type as far as the runtime is concerned, you have to write a convertor if you wish to include the original class. Web Services != Object Orientation.

Yeah, you're right, it should be independent... it's just a lot of extra work (my objects are much more complex than what I showed).
Thanks,

i am a learner in asp.net. i want to know about web service in asp.net.
why we user web service?
how to use?
if any category in web service?
Thanks

To call methods on servers across a network, commonly the Internet or a Corporate Intranet.
Any_India wrote: how to use?
In general the web service publishes which methods are available and a tool is used to generate a set of client classes. The class used to communicate with the service is called a proxy.
Any_India wrote: if any category in web service?
I'm not 100% clear about this question. SOAP is the main technology this[^] explains the basics of a SOAP service for beginners to the subject. WCF is a Microsoft technology that is an enhancement over plain SOAP services. If you are going to implement a webservice in .net I'd start with WCF, it is easier IMO, and you can expose a plain SOAP endpoint if you need it.

Hi,
what's the web way to develop a multi language website? what's your advise?
Thanks...

That's a really broad topic, and the strategies for coping with this are numerous. At the very least - don't fix your layout; remember that some people use RTL and others use LTR; don't hardcode any strings - at the least, they should come from a resource file; don't hardcode references to images - certain images mean different things in different countries, and always respect the culture settings.

I started work in Jordan, and I've very recently had to ford this stream myself.
Everything Pete says in his post is sound: Extract Strings and Image references to Resx files. For your Default.aspx page you'll have Default.aspx.resx for the Invariant culture (This should be English: the browsers default to US-English, but you can select Arabic as the culture in some browsers.) You can then add Default.aspx.ar.resx for generic Arabic and add regional variations e.g. Default.aspx.ar-JO.resx. Note that the where the value isn't available in the most specific resx file, .net applies the next most specific then the invariant. So Jordanian --> Generic Arabic --> Invariant. If the user's browser is set to Arabic culture, the framework will attempt to get the Arabic version of the page.
I also found it useful to remove any styling from the ASPX page, and put it into a theme / css. file. Additionally I try to avoid css styling involving the words "left" or "right" though these are needed occasionally. Luckily pretty much any asp.net property can be set through the meta:resourcekey attribute, which includes the CssClass attribute, overriding the default style .
I found these very helpful:

and this if working with master pages:

how to select design patterns according to project
|
|
|
|
|
It is mostly about experience. Design patterns get their name from their repetitive nature. When you have seen one type of problem often enough you can tell when a similar solution would apply. Patterns can be at very different levels of the software architecture though. A pattern like the Party pattern is pretty high level and implies data models. A pattern like Observer can be much lower level and might only apply to an event on a single control like a button click or it could be very high level and be applied to a message queue in an enterprise service bus.
Be careful about patterns. They can be a lot like fads. When Microsoft released the MVC framework tons of people decided that they had to shove all their projects into that pattern. But if you only ever have one view and that view has to re-implement a lot of the business rules that would also go in the model (client side validators in the view and further validation in the domain objects), you aren't buying yourself much.

Obiously, its is based on the requirement. At the time of design, one should decide, what pattern best suits for the requirement. At some point, tailoring of an existing pattern ,might be required also.
|

|

Find a design patterns book/website, implement them, and understand why and when they are used. Then decide if any are applicable to your project given your requirements. Each design pattern is a solution to a problem, not a solution looking for a problem.
The original Gang of Four (GoF) patterns each had a specific use in mind. The idea behind the book was that if you had a problem there is probably some commonly used solution which can be applied without needing to re-invent the wheel. A second advantage is that the patterns were given names which developers can use as a kind of shorthand e.g. "I'll us a singleton class" as opposed to "I'll need to write a class to make sure that only one instance of it exists".
The problem is design patterns have become the latest thing, so everyone wants to say they use design patterns. Additionally there has been a design pattern explosion too (negating the "shorthand" effect). That's not to say there is anything wrong with the original research, just the way it has been taken up by the dev community.

Start off by working out what you actually want your project to do, and how you want it to work. Once you know that, you need to break the application down into smaller areas and start thinking about how to compartmentalize the different aspects of the app. Don't get hung up on designing for patterns; let it come naturally.

}
wht i have to do is store arrylist inside string.
after storing the values in string , i have to identify the email with "@" symbol if value contains @ symbol then i have to bind that values to array2
if anybody knows please let me know.

I have some suggestion for you
1. Why are you using ArrayList you can use Generic List instead.
2. You can use Regular Express to validate email.
3. you can fire Linq query to filter out your list
I know this is not answer but you should have to improve your programming using upgrade techniques
Thanks

5'd - everything you said here makes sense. Occasionally it is good to step back and look at the problem being solved and all your points are valid. I don't know why you have been downvoted.
