Two web applications question.

Good day!

I have an ASP.NET web application , but i want to add a forum.
I've choosen the YAF ( Yet Another Forum ). Since its a whole new ( different ) web application i'm having trouble hosting both ( because that way i'll have to pay for hosting every individual application ).
My goal is to achieve by url rewriting : forum.XXXXXXXX.com - the forum where www.XXXXXXXXX.com is the main domain name.
Is it possible for somehow merge the two applications ?
I'm not quite sure what to google

Regards, Hris

Are you not able to create a sub-domain for your
main domain without having to pay extra?

Good evening. Thanks for your quick response !

So what you are saying is that i need to buy a subdomain and host the forum application separately ?

MAC Validation failed on web cluster

I have an C# .NET web app...small but perfectly formed. We have upgraded to .NET2. We now get an error on navigating off 1 page. When the user clicks 1 of the 2 buttons the app crashes with the well know error.....

'Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that  configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

Now before you all shout 'put the machine code in the webconfig', I have, on all 7 of the the front ends. And it hasn't cured it. And if it is so important, then how come the rest of the app was working fine without it?

Now I know it's related to viewstate and the fact that the postback can go to another server but I don't know much more.

I have added <enableViewStateMac="false">, this works a treat, cures my problem but has been deemed an unnacceptable fix by our solution architect. Something to do with security.

And suggestions on my next move would be welcome.

Thanks

ASP.NET Webservice clients

Hello friends,

I made a simple ASP.NET Webservice with one methode that needs some parameters:

[WebMethod]
        public String Person(string Id, string username, string pw)
        {
           //do something
           //return string        
        }

My question is, can a PHP client use this service?

Thanks in advance.

Web Service can be consume by any one. As this is an SOAP XML format

As this is inside a file, means it should have a class. Create the object of that class and call the method.

You have declare your Function like this

Public Function byteArrayToImage(ByVal byteArrayIn As Byte()) As Image
Dim ms As New MemoryStream(byteArrayIn)
Dim returnImage As Image = Image.FromStream(ms)

Return returnImage
End Function

now if you have declare this in same page , then you can access it like this

Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.SelectedIndexChanged

obj.byteArrayToImage(byteArrayIn)


End Sub

but if you have this in a Different class , then you have to create an object of a Class like this

MyClass obj = new MyClass

obj.byteArrayToImage(byteArrayIn)

Hope this Helps

Set default input language of a text box

Hi,
I want to change my textbox default input language,
Currently the default language is English and in order to change it, the user has to hit ALT+SHIFT keys...

Re: Set default input language of a text box

Abhishek Sur6-Aug-09 9:50

you mean to change the language of a textbox. Its totally dependent on the client browser configuration. Well, what google does is it changes the script through trapping the keystrokes.

You may send keystrokes to the server and process it to get the script in actual language. Use AJAX request to the server. Just create an http handler to process those requests.

hope you got my point. In this way you can also place quick suggestions as well... Cool | :cool:

Application Begin request is not getting called

Hi all,

I have created menu controls with the help of

<code><ul><li><a></code>
tag. The url page defined in the href attribute of anchor tag does not actually exist in the application directory instead, it comes from database and the logic for it is written in the application begin request event in global.asax.cs. but this event is getting called only once and is not getting fired whenever any menu is clicked. Please tell what could be the reason for it. If this event will not be called dynamic pages will not be created. Please help me.

yield return

Hi,
I am using a enumerable function using "yield return". This allows me to iterate through the items using for each loop. Since this is a lazy evaluation, after each iteration the control returns to the calling function.

How can I use the enumerable function without for each loop?

public static IEnumerable<int> GetValuesUpto(int n)
{

for(int ctr = 1;ctr<=n;ctr++)
{
yield return ctr;
}
}

So, when I call this function i.e.
int[] arr = GetValuesUpto(10);

What would be the result, will it work like a lazy evaluation and will return only the first value, or will it return the desired result?

Waiting for your replies guys!!
Vishwjeet

Iterator blocks are called when you want to fetch the data from the Enumerable.

Actually if you call the the function, it will not be called. Rather if you do a foreach on the Enumerable object the function will be called and will return you 10. Wink | ;)

Just change your code a bit as I did:

IEnumerable<int> arr = Documented.GetValuesUpto(10);
MessageBox.Show(arr.ToList<int>().Count.ToString());

public static IEnumerable<int> GetValuesUpto(int n)
{

    for (int ctr = 1; ctr <= n; ctr++)
    {

       yield return ctr;
    }
            
}

Put a breakpoint in the line IEnumerable<int> arr = Documented.GetValuesUpto(10);. and also a breakpoint within GetValueUpto block. You will see the function is called when we try to call ToList() rather than the actual call to GetValueUpto. This is the main advantage of iterator blocks.
