Hello,
Now, I develop communication tool using udp protocol.
When I send data, I use send() in C#'s Socket class.
If a recipient tool is exist, a sender send it.
If not, sendTo() waiting some seconds.
Maybe after 10 seconds, the error occured.
I'd like to send it no waiting whether recipients is exist or not.
I investigated Socket class( expecially, SetSocketOption ),
But I have no idea.
If you have some ideas, please tell me.
Thank you in advance for your kindness.

1. You can use ODBC and read Excel data. That data you can store anywhere you want.
2. Using Excel.Application object, you can read information form Excel sheet and save it to array or where ever you want.

I have say a 100x100 array of gray values (0 to 255). How can I create a 8bpp bitmap from this array such that 0 maps to black 255 maps to white?
In particular how to you set the ColorPalette for a 8bpp image; I want 0 to map to black 255 to white?
I tried following code but its giving me problems:
PixelFormat pf = PixelFormat.Format8bppIndexed;
byte[] Scan0 = CalculateIntensityValues();
Bitmap bmp = new Bitmap(100, 100, 100, pf, Scan0);
how to convert Scan0 from byte[] to IntPtr?

Scan0 is a pointer to the bitmap data. The easiest thing to do is to create the bitmap, then get access to the pointer and set the values in an unsafe block. None of this code is setting up a palette, as far as I can see.

Dear *.*
I'm a c#-rooky *g*. How can I call word/outlook from an existing c#-app. The users just want to start word or outlook by pressing a simple button within the form.
An additional nice feature would be for example submitting the email-adress to outlook or something like this.
regards
Klaus

You need to add reference of Word and outlook libraries in your project. Then you can do whatever you want using Application objects of these libraries.
If you are using Office Xp, library 10.0 will be available on your system. And if it is 2003, you will see library 11.0
Enjoy

Ashish,
thanks a lot for open my eyes . After thinking it over, I've also found many samples on the net (msdn).

I've in my application an infinite number of object displayed on the form that are made dinamically by the user.
The user define the position, the size and the color.
I've implement this by a linked list.
Now i want to save this linked list inside a ASCII file so i can load in a second time and recreate this objects.
In your opinion what is the easer way to do that?

 take a look at some classes from System.Collections, especially ArrayList, Hashtable and similar...

Does it have to be ASCII ? Again, take a look at System.Serialization.
Do not reinvent the wheel.
Search for them on http://msdn.microsoft.com/[^].

Sorry i've maybe explained bad.
I know about ArrayList and Serialization, the problem is implement this to an invinite Linked list, how could i concettually linked list in a file?
Maybe it is easy but i don't understand how?
Have i to loop for all the list's son and save one at time in the file?
But how can i read it then?

uh. I understand this even worse

No, serializer will do that for you.
Sasuko wrote:

Using deserialization.
Search Google for keywords "Serialization of ArrayList". There are many examples. It's actually easier then it looks.

can you submit some details
|

i've found nothing about that on google! Can you show me where?
|

the problem is that array is finite, linked list no!
It does work the same?
|
|
|
|
|
Forget about linked list.

Who says so? ArrayList is growing array, that means if there is no place for new item, it re-create array with double size... There isn't limit. ArrayList is actually much better then linked list implemented by yourself.
"The capacity of an ArrayList is the number of elements the list can hold. As elements are added to an ArrayList, the capacity is automatically increased as required through reallocation."
How on earth you can think that ArrayList is somehow limited but linked list isn't? Did you even try to look up what ArrayList actually is?! link[^]

Really thanks for your interesting.
I let you know...

a recursive method to check if a lined list is sorted
method should return true if it is sorted in ascending order, false otherwise
|
|
|
|
|
what you mean by recursive method?
like this?
bool checkNode( IListItem node )
{
static something lastValue;
static bool sorted = true;
if( node == null )
{
return true;
}
if( lastValue > IListItem.Value )
{
return false;
}
else
{
lastNode = node;
return ( checkNode( node.Next ) );
}
}
What a stupid method. If you tell me why it is so stupid, maybe I'll teach you how write more stupid code like this.
