Building through XSD, yes it does. From straight XML there's no way to specify inheritance. Or were you asking about Pseudo code?

Hi!
I'm usimg bindingsource filter property to sort out the data I need..
I know that this property supports sql wildcard '%' as a substitution for a array of chars.
is there a wildcard that substitutes only one char??

ex. i've got this list
aaazzz11
aaazzz12
aazzzf13

and i want only those items where three letters counting from fourth are 'z' ie aaazzz11 and aaazzz12
now in sql I'd write "like '___zzz%' "
but '_' doesn't work in bs..

thanks for any help!!

internal protected is a superset of internal and protected. Was this your understanding?

These are access specifiers,
If we use "protected" before a method/variable, it can be accessed only to derived class.
If we use "internal" before a method/variable, it can be access only within the same assembly.
So, internal protected can be accessed within the same assembly as well as in derived class.
Hope this served your purpose.;P

Communicate between windows and linux box

Hi,
I have two different services; those are running under windows box and Linux box. Both Windows and Linux services had been developed by .NET by the help of respective SDK’s. Both business service systems are running fine based on its scope. But now, I wanted to implement a communication channel or some mechanism, which will help these different services to share objects/data. Apart from that, I am not allowed to use web interfaces to facilitate the communication since both windows and Linux machines resides in same intranet.

Is it possible to communicate between two distinct OS environment using .NET remoting?
If so, what could be the fine tuned way to achieve the same?
What are the other possible thoughts to implement the same apart from remoting and web service?

Any thoughts / url/ sample application will be appreciated.

Thanks in advance.

Alphabetising an array using OrderBy

JamesBarnes10-Aug-07 2:31

Items[] ItemsArray = new Items[100];<br />
Items[] AlphabetisedItemsArray = new Items[100];

I have an Items array of size 1*100, now lets say i have populated that array, and want to organise its elements in alphabetical order, by item name.

I think the code should be something like this :

AlphabetisedItemsArray = ItemsArray.OrderBy(ItemsArray,Items.getItemName)

If it helps at all, here is the structure of the items class:

public class Items<br />
    {<br />
        string Name; //40 bytes<br />
<br />
            public void SetName(string aName)<br />
            {<br />
                Name = aName;<br />
            }<br />
            public string GetName()<br />
            {<br />
                return Name;<br />
            }<br />
}<br />

Any help is greatly appreciated, thanks =)

Look at Array.Sort. You will need to define an IComparer for your Items class.

In .NET 2 there will be a generic version of this I suspect.

i ended up doing it manually =)

while (c < NumberOfRecords)<br />
            {<br />
<br />
                while (index < NumberOfRecords)<br />
                {<br />
                    AlphaItem = AlphabetisedItemNames[c];<br />
                    NonAlphaItem = ItemsArray[index].GetName();<br />
<br />
                    if (NonAlphaItem == AlphaItem)<br />
                    {<br />
                        AlphabetisedItemsArray[c] = ItemsArray[index];<br />
<br />
                        c++;<br />
<br />
                        if (c < NumberOfRecords)<br />
                        { index = 0; }<br />
                        else<br />
                        { index = NumberOfRecords; }<br />
                        <br />
                    }<br />

Like Kevin said, but you can make it a little easier on yourself by defining a function with a Comparison<Items> signature:

Items[] theItems = ...;
Array.Sort<Items>(theItems, CompareItems);

...

int CompareItems(Items first, Items second)
{
   return first.Name.CompareTo(second.Name);
}

Environment Variable USERNAME returns null reference error for Service Account

Rajni P10-Aug-07 0:34

10-Aug-07 0:34

When executing the code -

Environment.GetEnvironmentVariable("USERNAME").ToString(CultureInfo.CurrentCulture)

under the Service Account gives the error -
'Object reference not set to an instance of an object'.

Running the same code using a local machine accounts credentials does not fail.

Pls help me with the possible cause and resolution.

Cheers !

Hi,

when there is no user, what in your opinion should the value be for:
Environment.GetEnvironmentVariable("USERNAME") ??

and who's culture do you want then ?

You should check for null, and maybe work with a default if that makes sense at all.

Smile | :)

As long as you have the printer driver installed, you can "draw" the slip however you want. And no, I'm not going to write the code for you before you ask.

Deja View - the feeling that you've seen this post before.
