OK. Don't call me only ignorant* but pesimistic ignorant from now. My theory is better say something obvious again than forget to say something critical.

you mean "that rookie" ? Sorry than.. I am so stupid I cannot remember who was author of original post as I see only post I am replying to... so I had to use something else than your name... well i could use "s/he" ... *click* another lesson learnt
At the top of the things, I always had problems (nope, I never... others have problem wit me ) to be polite... and I am not going to change myself in this way much... sorry man that's the way I am.

ok , the critical thing is not critical for me right now, and when I consider the example , it enlightened me a lot..So I didnt intend to write or answer about the IDispose..
I wont talk about about the politeness , thats your choice , and if you like the way ppl threaten to you , than everything is fine..
Whatever, I know your are trying to help ppl , the way you do..it is ok for me...

Ah, yes, there is that. But all that will be corrected when we get generics...

Well, if he truly was a rookie, it wasn't bad. But he could be a very good C programmer that is about to learn OOP, in that case, he would probably find rookie a bit insulting 
I was a consultant in a .NET project a couple of years ago (a very bold decision from a big company to use the brand new technology), where more than half of the staff were new to OOP, and they certainly weren't at home with GC.
I used a lot of hours reeding out resource leaks by inserting dispose() invocations and encapsulating functionality inside using(...) blocks.
I even had to expose my ears to statements like: "Hey, look what Bob did!, isn't it clever?, now we can use this code in blah blah blah", the guy was talking about 'bob' having implemented a class for Gods sake!
But I never considered them rookies, at many points, some of them were much more experienced programmers, than I was.

Oh yeah...  I was thinking in contex of what he is learing... bt no one can know what I am thinking unless I write it down  - my fault. I understand now...

Hi
I have done a c# program which reads a schema file and automatically inserts data's according to the datatypes. Now I have another xml file which has original values in it. So while my program is raeading a schema file, if there is field which is same field name of an original values cxml file. my program should read the values of the the original values xml file of that field and insert into the resultant one.
i AM TRYING AS SUCH
ie,
I have used switch ..case in my program
[b]switch(dColmn.DataType.ToString())
{
case "System.String":
if(dColmn.ColumnName.Equals("billto_name"))
{
XmlTextReader xtr = new XmlTextReader("D:\\billtoname.xml");
oValues[i] = ((xtr.NodeType == XmlNodeType.Element) & (xtr.Name == "billto_name"));
}
else
oValues[i] = (string) "Castle Hampers" + j;
break;[/b]
Note:
//***** billto_name is the field which exists in both the schema and original values xml file.//
// j is a for loop for about 0 to 200
the if statemnt given inside is the one I am trying . But when run , the data's inside are shown as "false".

hi,
I wrote you long and detailed response, bt I hit some mouse combo or what and lost it before I post it 
so:
don't even try [b] there are <b> and better <code> for marking code snippets in post
johnsanthosh wrote:
XmlTextReader xtr = new XmlTextReader("D:\\billtoname.xml");
shouldn't be inside loop.. you don't have to create it again and again... inefficient. And it's even mistake here!
Plus you don't call xtr.Read()
You must call XmlTextReader.Read() method in order to advance to next node in XML stream... that's why it gets wrong there...
hope it help I rush to post it I don't want to screw again
best regards,

Hi
Thank you for your response.
Can U please give a some more detailed note about it.
As its very urgent for me to do.
pls

sorry for late response as I am +6 time zone so you ca count what time it was for me 
<br />
if(dColmn.ColumnName.Equals("billto_name"))<br />
{<br />
XmlTextReader xtr = new XmlTextReader("D:\\billtoname.xml");<br />
oValues[i] = ((xtr.NodeType == XmlNodeType.Element) && (xtr.Name == "billto_name"));<br />
<br />
}<br />
You must call XmlTextReader.Read()[^] to move to another node in XML stream (File, in this case). Since you don't do it, xtr.NodeType & xtr.Name are null (IMO)...
(btw there should be && not bitwise & operator)
As I reread you post, I must ask why there is loop from 1 to 200 or so...
If I understand you have xml file with schema, xml file with values and you are trying to create one more file with...? or? now I don't know
At least you know now how to read XML files with XmlTextReader...
tell me more about what exactly you want to do and I'll (or somebody else) will hopefully tell you how to do it...

Hi
First of thank you for replying.
I have to read any schema file, and according to their datatype, it should load values for about 200 into a new xml file.
ie, a rough xml(first file -resulatant file)
<name>john1
<salary>8100
<name>john2
<salary>8200
<name>john3
<salary>8300
<name>john4
<salary>8400
like so on.. for about 200 values.
Now I have another xml file which has same "name" field all meaningful values for about 50.
(second xml file)
<name>john milton
<name>stephen
<name>george
<name>thomas
<name>paul like so on for about 50 data's.
Now coming to my program, when it reads the schema, and when the schema file has the field"name" then it should read the second file and insert the data's from second file into the first xml (resultant file) for that particular field.
This is my requirement.
and this is my coding done, after running this program i find the values for the particular field are changed to false.
private void button2_Click(object sender, System.EventArgs e)
{
dataSet1.ReadXmlSchema(txtSchema.Text);
foreach (DataTable dTbl in dataSet1.Tables)
{
for(int j = 0; j <= 20; j++)
{
object[] oValues = new object[dTbl.Columns.Count];
int i = 0;
foreach (DataColumn dColmn in dTbl.Columns)
{
switch(dColmn.DataType.ToString())
{
case "System.String":
if(dColmn.ColumnName.Equals("billto_name"))
{
XmlTextReader xtr = new XmlTextReader("C:\\CDEV\\testdatagenerator\\meelu.xml");
oValues[i] = ((xtr.NodeType == XmlNodeType.Element) && (xtr.Name == "billto_name"));
}
else
{
oValues[i] = (string) "sachin" + j;
}
break;
}
i = i+1;
}
dTbl.Rows.Add(oValues);
}
}
dataSet1.WriteXml(txtXml.Text,XmlWriteMode.WriteSchema );
}

sorry
I had given tags for the above program so, it is not in clear xml format.
for first xml file
ie john1,john2,.... comes for a field "name" tag(element)
and 8100,8200,8300..etxc comes for "slary" tag(element)
second xml file
ie, john milton, stephen,george, thomas,paul all comes for a field " name" tag(element)
so now i have insert the data's form second xml file and load those values to the same field of first xml file.

Is there a way to 'lock' an entire folder, not just a file in side? I read this: http://www.codeproject.com/csharp/CryptoSafe.asp[^] and it lays out the info very well, but is there a way to adapt it to do an entire folder so that it cant be opened?
|

The only way you're going to accomplish anything like this is to Crpto every file in the folder. There is no way to do the same for the folder itself.

this will be difficult as some files will be very large ( 500mb or bigger). I and speed is very important.

Like I said, it's not possible to do it on the folder itself. In order to accomplish something like this, you'd have to replace the NFTS File System with your own implementation.
Since security is an issue, look into using the security system that's built into Windows and/or whatever network your using to control access to these resources. That's what it's there for...

Maybe I missed the point here but I though this thread is about encrypting all files in a folder and that is actually supported by NTFS.

Like I told him, encrypting the FOLDER isn't possible because it's just a pointer to a list in the file table. Encrypting the contents of the folder is possible using either an external program or using the NTFS encryption. But in the latter case, he'll still need to go read the documentation on it to understand how to use it.
Most of the time, when someone posts a question like "how can I password protect a file or folder so noone else can open it", it usually means that they want to protect every file in a folder so you can't even open it in Notepad without a password box coming up.
This question was no different, and I referred him to the security features of the OS, be it using ACL's to control access or encryption. The choice is up to him, so long as he reads about the features and pitfalls of each and understands them.

A folder is actually a file with certain attributes (see The NTFS File System[^] section NTFS File Attributes). As folders have an encryption attribute too, you can use this to ensure encryption of files that will be created in that folder (given that nobody disables ACL inheritance). By the way, the documentation states that you can encrypt files and folder so I assume that in case you set the encryption flag for a folder the file (which represents the folder) is also encrypted (yeah, I know, that does not answer the original question ).
Dave Kreskowiak wrote:

It seems that you only need the function EncryptFile()[^] (but there is also a more detailed article about that titled A Programmer's Perspective on NTFS 2000[^]).

I definitely agree about that!

Great! Now that the detail of his project actually come out, all of this was moot.

Ok so then I guess my next question is about folder hiding. How secure is this method?
|
|
|
|

Not at all...
Like I said, look into the security features of NTFS. It's the ONLY method that will allow you to secure a folder so only certain people/groups can see what's inside.

Let me explain what I am trying to do. I am trying to create an electronic file distribution program, much like Steam. Unlike Steam, I want any game developer who wants to use it, the option to. What I am looking to do is require as little code moddification on the devs part. What I want to happen is that the entire game is downloaded in one file (could be an encypted folder or some varient of a zip file). When the user runs this program it checks the database (online mode) or a file stored on the user's machine (offline mode) to see if the user has permission to unencrypt / unzip the folder and run the contents. This leads to a problem that the decrypted / unziped files can not be placed onto the user's harddrive in as accessible manner as doing so would allow a devious user to just obtain these files from another user who has legit permission. Thus receiving a free game. Any thoughts on how this can be done?
