10/5/2008 = 4
11/5/2008 = 4
12/5/2008 = 4 + 3

Hmmm... lets see, this can be done using a HashTable.
First make empty string entries with keys equal to the dates present in the range.
Then iterate through each date range you have, and map the corresponding entry into the HashTable seperated by a +

Hello everyone,
In IIS, we can set the directory security of some virtual directory to .Net Passport authentication. I am very interested in this feature. But I am not sure that if I configure IIS in this way,
- Which .Net passport account should I use? Could I use the public MSN ID/Live ID applied from Microsoft (which we use to login MSN messenger) or should be use some other kinds .Net Passport ID?
- I learned if a web site is involved to use .Net Passport based authentication, web site delegates authentication work to .Net Passport login server, and the .Net passport login server is involved to do real authentication and ticket assignment. I am wondering if I use .Net Passport based authentication in the web site I setup, should I configure some .Net passport login server? If ues, how? I searched for quite some time but not found related documents regarding this setup.
thanks in advance,
George

You should turn option strict on in your project, so that you get an error message telling you that you are using the variable stream1 that is not declared anywhere.
Despite everything, the person most likely to be fooling you next is yourself.

What do you mean? You open stream2 and close stream1 (which doesn't exist in the code that you posted), that is definitely a problem.
It might not be your only problem, though. On which line do you get the error message?
Edit:
You should name your variables to something more descriptive than stream1 and stream2, that way you are not so likely to mix them up.
Despite everything, the person most likely to be fooling you next is yourself.

No, you are right. There isn't. I was thinking of VB, where such a mistake is usually caused by not using strict mode.

Use this routine (doesn´t crash with *.gifs) 
public static byte[] ReadFile(string image_path)
{
byte[] data = null;
FileInfo file_info = new FileInfo(image_path);
long bytes_count = file_info.Length;
FileStream file_stream = new FileStream(image_path, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(file_stream);
data = br.ReadBytes((int)bytes_count);
return data;
}

Hi,
You probably want to take a look at Reflection.
Also, while I realise your first language may not be English, I suggest you run your posts through some form of English spellchecker (the Google toolbar has one), and if possible a grammar checker. You may find that helps you get better results.

Perhaps you should rephrase your question. It doesn't make any sense (or it's too general).

Have you done a search on this? There should be plenty of documentation on how to do so.

Simply press F1 on TreeView class and you'll get something like: TreeView Class[^]. If you scroll down a bit you'll find good basic examples.

Hello!
Yesterday I posted an article, which tried exactly to explain my problems with Linq2Sql - Dataclasses.
It contained 3 questions, but the simply answer I got were 2 Ratings of "1", so from now on noone will find that article anymore.
So I ask you again, please to help me.
My questions in short are:
- How can I define in the DataClass-Designer an Linq2Sql-Association with deletrule.cascade ?
- Is there a more simple way to add Entities directly to a Table<TEntity> (without submitting data to the DB)?
- How can I enforce the Datacontext to submit Delete-Commands, when I delete a Child-Entity from a DataGridview (actually it submits an Update, which sets the Child.ParentID to null)?
As I said, my questions are asked more detailed in that article[^], and are shipped with a sample-project to make it easy to reproduce my problems.

Well Mr poorenglish an article is supposed to be an informative, instructional contribution from you to CP. If you pose a complex question in an article then you must expect it to be vetoed as a rubish article.
If you look at the forum list you will find a forum for LINQ and dotnet 3.5. I suggest you pose the questions in that forum and just possibly you may get an answer.
Never underestimate the power of human stupidity
