uctrlobj.panel2.visible=false;
Hope u got it.

when a file is created, all information (file name, creation date, size etc) are stored anywhere.
so keeping these points in mind,
how these information can be accessed.
these information is also called signature of a file.

Use:
FileInfo fi = new FileInfo(@"c:\test.xml");

Your suggestions are prone to criticisms, especially the theoretical assumptions about how the mind is at work.

1) Open VS.net 2005.
2) Mash Face on keyboard for 1-2 minuites
3) Bandage Face
4) Press "Compile"
5) Debug
Repeat steps 4-5 until your program works.

Hello everybody,
I'm working on a C# application (.Net framework 1.1) that is gonna be used as
an HTML editor.It uses Microsoft MSHTML API for editing HTML pages. Now most
of the job looks good and it is dealing fine with Bold , Italic, Underline,
Open file, Save file and other features as well. The problem is that I can
not find a way to insert a <table> element into the page(HTML document) or
edit an existing TABLE at run time. Anybody got a clue?
TIA
yours,
P.Assadi M.D.

Actually it was solved in a way, you can add "Table" tags as STRING
and add them to document.innerHTML. they will be recognized as an HTML
element.
thanks anyway

I have a database containing a many-to-many relationship and want to display it using two datagrids in the usual master-detail style. For illustration let's say I have a movie table, an actor table and an appearsIn relation table representing the many-to-many relationship between movies and actors. The master datagrid should display movies and the details datagrid should display all actors that appear in the selected movie. The number of actors that can appear in a movie could be in the thousands, so selecting the actors to display must be efficient. It appears that .Net directly supports one-to-many relationships, but not many-to-many relationships, and thus I can't seem to find an obvious solution which is efficient and elegant. I've tried filtering the actors table using rowfilter like this "id in (1,2,7,9,.....)" but that's way too slow if the number of ids to filter on gets very big.
Any suggestions?

Hi,
actually, malware signature (in this case spyware signature) is a set of parameters that helps you recognize whether the specific file is malware or not. Basically, it may be a unic sequence of bytes, specific for that file or for that malware family.
In case you want to develope your own anti-malware tool you should, first of all, learn the PE (portable executable) file format, you may find the needed documentation on MSDN.
Unfortunately, you'll have to build your own signature database, because all the AV vendors keep their sigs in secret.
You should use simple binary IO (System.IO namespace) for accessing the files (those you think are malicious) and your signature database.
cheers,
Alexey

hi all.
how to get information hidden in the header of a file
or
how to get information about the signature (name, version, creation date, modified date etc)of a file
muhammad mahmood ilyas
|
|

|
|
Depends on the file type. For a description of file types you might check this link.
Basically you craete a BinaryReader. You can then read the complete header with ReadBytes(count) and convert them yourself, or you can read them information by information, like ReadInt, ReadBoolean etc.

u can try
System.IO.FileInfo fl = new System.IO.FileInfo("full path of file");
and from this fl object u can check name, version, creation date, modified date etc of that file

I have a string, which i'm retrieving from the database, and i need to identify whether the string is unicode or not.
Either by string, or by enumerating the charachters and identifying if they are unicode.
I've had no luck in my own searches. (.net 1.1)
Cheers
Tris

Here is the implementation for you:
bool IsCharUnicode(char c)
{
return true;
}
Any string is Unicode in C#. The database access layer must transform the string to or from Unicode (except any decent database would use Unicode anyway) - it is not your problem.
If it fails, then it is broken. If you have to live with a broken access layer you might use the encoding classes to go from the broken string representation back to bytes, and then another encoding to get the correct string. This will only work if the database access layer converts it using an encoding where every byte sequence can be matched to a single string (for example codepage 1252). Yes, I know this is not clearly written, but it will have to do.

I have to work an output into a system that was built on UTF-7 strings / files, but now requires a degree of Unicode support. So all Unicode strings need to be converted to HEX and stored in a specialy flagged field.
Unfortunately, i can't encode normal strings, as this will interfear with the legacy data.
I really need a way of determinging if a charachter is exclusively available in Unicode.
Hope that clears things up. :/
Cheers

UTF-7 strings ARE unicode strings. More specifically it is a 7 bit encoding of the Unicode character set - just like UTF-8, UTF-16 and UTF-32 are 8, 16, and 32 bit encodings.
If you have read a string as if it was ASCII, but it actually contains UTF-7, convert as follows (from memory, so expect typos etc):
Encoding.UTF7.GetString(Encoding.ASCII.GetBytes(theString))
To generate a UTF7 encoded string that will turn out correct when set as an ASCII text do this:
Encoding.ASCII.GetString(Encoding.UTF7.GetBytes(theString))
If the result of the conversion is the same as what you started with - then it does not require any conversion, so a simple string comparison will be enough to tell you, but you really do not need this if you already have UTF7, just convert everything.
Also notice that besides maybe Klingon and the likes, you should expect every character to be available though at least ONE codepage besides Unicode. You need to think about it as "does this codepage support this character", not as "Does this character require Unicode", as the latter simply does not have a defined result.

This is purely for the back end.
It's required to send Indian, Chinese, Japanese, Arabic, Hebrew etc, all through the same data stream. Fun Fun 
You have me on the right track now tho, cheers.

Hi.
Im running a private live communications server and I would now like to add windows messenger-like functionality to an application which will use this server to communicate.
Whats the best way of doing this?
Can you integrate the windows messenger client directly in some way (preferably with full control) or do you have to create your own client? If so, which api is best to use, the RTC api or some messenger api?
regards
/Rickard
