I know that the SID is the only constant thing in a users account, but it is public isn't it?
An administrator can easily read all SIDs of users in a network. Therefore, using just the SID is a bad idea, too...
Any other way?
Thanks for your reply and best regards

I've just found a solution and wanted to quickly let you know it, in case it's interesting for you, too:
First, a random byte array is generated using a cryptographically secure random number generator. This is the key used for encryption. It is protected using ProtectedData.Protect with the DataProtectionScope.CurrentUser option and written to the registry.
When loading, the protected key is retrieved from the registry, unprotected using ProtectedData.Unprotect and used as decryption key for our file.
I'm not sure what data ProtectedData is using, but it seems that the password can be changed, without making the ProtectedData behavior change, i.e. the user's password actually doesn't matter. Same applies to the user name. Probably Windows keeps some secret key for each user, which we can't access manually.
Best regards

Hi,
A stored procedure runs three select queries.
Each of these select queries is being assigned to a table (See below).
The question is: In this case I know how many tables are returned so I use the "oDA.TableMappings.Add" three times. But what if I do not know how many tables are returned? How can I make a dynamic loop arouond "oDA.TableMappings.Add"?
Alternatively, Is it better to retrieve the whole of data into one dataset and then separate the data into datatables?
This is what I am doing at present:
SqlDataAdapter oDA = new SqlDataAdapter(oCmd);
//use Tablemappings to name the retrieved tables...
//otherwise have to use indexes to refer to each table...
oDA.TableMappings.Add("Table", "Curves1");
oDA.TableMappings.Add("Table1", "Curves2");
oDA.TableMappings.Add("Table2", "Curves3");
DataSet dsData = new DataSet();
oDA.Fill(dsData);
This is what I am trying to do:
SqlDataAdapter oDA = new SqlDataAdapter(oCmd);
int i = 0;
foreach(table in oDA)
{
oDA.TableMappings.Add("Table" + i, "Curves" + i);
}
DataSet dsData = new DataSet();
oDA.Fill(dsData);

Hi,
I'm new to C# and need some help with scrolling in panels.
I have a PictureBox (PB1) on a Panel in a Windows Forms appliction. PB1 is larger than the panel so scrollbars are needed on the panel. The Panel's AutoScroll property is set to true and the PictureBox's SizeMode is set to autosize. I have added a small PictureBox (PB2) on top of PB1 (in the upper left corner of PB1). So far, everything is ok and displayed as intended.
Now, I want to drag & drop PB2 from the upper left corner of PB1 to the lower right corner of PB1. But since I cannot see the right hand side of PB1 (it is larger than the panel) then the panel needs to scroll PB1 to the right and down when the dragged PB2 is close or on the right and lower borders of the panel.
Is there any information out there that can point me to the right direction how the scrolling can be implemented?
Regards,

hello,
I've got the following regexpression:
"<span .*bbc_underline.*>(.*)</span>"
and the following input string:
"this <span class="bbc_underline">is underlined <span class="bbc_strikethrough">and striked through</span>text.</span>"
when I do a replace on the expression, I get the following result:
"this text."
I'm quite new to regular expressions. the goal in the expression above is to yield the following result:
"this [u]is underlined [s]and striked through[/s]test.[u]"
but somehow, the first expression eats up more then it should. btw, I don't know if or what is nested. I just have a couple of span's with given classes, that will "turn into" square brackets. can somebody please help? A ton of thanks in advance.

I would normally use:
"<span [^>]*bbc_underline[^>]*>([^<]*)</span>" The "^" within square-brackets says that the RE parser can match any character except the specified ones. I cannot remember if you need to use a backslash to escape the "<" character.
Your example text contains nest spans, so the above RE would match the inner "strickthrough" span on the first pass, then the outer "underline" span on the following pass.
You might find that the "Greedy and Lazy" section of http://www.codeproject.com/dotnet/RegexTutorial.asp[^] can simplify the expression.
Hope that helps.

hey andy,
lot of thanks for your reply. I've tried it out but the RE you've provided does not work. In the meantime, I came up with this expression
"<span .*?bbc_underline.*?>(.*?)</span>"
...but it does not work correctly either, since it matches the first occurence of </span> instead of the last.
In the case I did not explain it correctly: What I want to achive is to match the first occurence of <span SOMETHING "bbc_underline"> with the last possible occurence of </span> and replace everything within with [u]$1[/u]. I don't know how many nestings there are. The span classes I use come from a predefined list (bbc_underline, bbc_italic, bbc_strikethrough and the like)
I would greatly appreceate further help.
Matthias

Hello,
I´d like to program a simple Program in C# with a windows form as the main window. From the main menu I want to open a plugin-dll which automatically extends my main menu with new plugin-specific entries.
I read the article about the Razor framework, which really is a nice work, but it is way too complex for my needs.
Any Ideas?
Thank you,
Oliver

Normally you would define an interface, such as IPlugin, which your application would recognise and which the plugins would conform to. This would have a set of methods that plugins would have to provide the implementation for. Your methods could be something along the lines of:
public interface IPlugin
{
void Loading();
void DoWork();
void Shutdown();
}
Next, you need a mechanism to recognise plugins. This could be by having them loaded from a certain directory, or having a config file which lists the plugins associated with your application.
Finally, you need to load these plugins in. This can be loaded using Activator.CreateInstance.

Thank you very much...
But how can I extend my menu entries in the main window when the plugin is loaded? The main program should not know anything about the functions of the plugin.
Thanks,
Oliver

It looks like your IIS has not been configured with asp.net. You'll need to register it - run C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe

Thanks for the input....
I tried registering the same from the path mentioned.
But it dinn't help me , gives the same error message.
Is there any other workaround / solution for this issue.
Thanks & Regards,
