Hey, I'm trying to build my own ICryptoTransform-able class, so I could use it in CryptoStream, because as I know of, 2 chars in hebrew, transformed (in almost any transformable there is in System.Security.Cryptography) to 24 chars, so I would like to create my own so it wouldn't be so much... I already built the algoritm, and I inherited from ICryptoTransform as they wanted to, and I'm using MSDN to know what methods and properties I need to do, but there are two properties I don't know what to do with them, and what I should return from them... the properties are InputBlockSize AND OuputBlockSize, if anyone can tell me what to do in them, and even give me an exemple I would appriciate it...
oh and another thinh, can some-one tell me in the TransformBlock and TransformFinalBlock, what does every parameter stand for, and what do I need to return from it?

I want to trap the page break event at runtime.I can't able to trap the page break at runtime in a running word document.
Requirement :
- When columns in a table span pages, need to repeat the column heading row at start of each page .Column means to say the total no of rows in a page is greater than the rows that can be printed in a single page, then in that case we have to repeat the column heading into the next page as well.
If anyone have any idea to implement this condition then please give your suggestions

I found the answer myself.
First, set maximize the child form in Form load event.
Second, set ControlBox of the child form to be False.

there is one BEST way which I recomend, without using static variables and distroying your code, simply, go to frmSecondForm.cs, and you will see a Constructor, simply add parameters in it, i'll give you the example and then explain:
public frmSecondForm(object myFirstVariable, string mySecondVariable, Form prevForm)
all you need to do, is to add before that private variables, and then simply placing them from the constructor to the variables, and there you go.
Why Form prevForm?
that's how you can control the last form either, when you want (as you want - your click event on btnShowFirstForm), you just do:
prevForm.Show();<br />
this.Close();
ofcourse in the first form, you can't do the close method, cuz it will close your whole program, because it's the main [first] form opened.
Hope I helped... NaNg

Answer 1:
On Click event of btnShowFirstForm write this code
frmSecondForm.Show();<br />
frmFirstForm.Hide();<br />
On Click event of btnShowSecondForm write this code
frmFirstForm.Show();<br />
frmSecondForm.Hide();
Answer 2:
Declare variables as public and call them from second form like this:
<br />
frmFirstForm f1 = new frmFirstForm();<br />
string getvalue = f1.varablename;<br />

How about recompiling your component under 1.1 and using this instead?

How about telling us what the error message is?

Im just starting to play with manipulating Active Directory using C# (never done any C# before).
I've followed some examples and extracted data for a given user, but its returning some odd data as follows:
badPasswordTime = System.__ComObject
lastLogoff = System.__ComObject
lastLogon = System.__ComObject
pwdLastSet = System.__ComObject
What is "System.__ComObject" and why am I not getting numeric data back?
Am I doing something wrong or missing something?
The code I am using (just a sample pulled off the web) is as follows:
<code> static void Main(string[] args)
{
string path = "LDAP://domain.com";
DirectoryEntry entry = new DirectoryEntry(path,"USERNAME","PASSWORD");
try{
Object native = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=ADTEST)";
foreach(SearchResult result in search.FindAll())
{
DirectoryEntry dirEntry = result.GetDirectoryEntry();
foreach (string key in dirEntry.Properties.PropertyNames)
{
foreach (Object propValue in dirEntry.Properties[key])
{
Console.WriteLine(key + " = " + propValue);
}
}
}
}
catch( Exception ex )
{ throw new Exception(ex.Message); }
Console.ReadKey();
}
}
}</code>
Any suggestions welcomed.......Thanks!

i think there should not be any problem in this case. Simply get the selected values from list and pass them to get values from database for datagrid.

Hi everybody.
I have a project which is developed by visual c#.net by visual studio 2005.
It is a database project and because of damaging the connection in anywhere of my application, I put the main method in try catch block which handles SqlException.
When I run the application, the try catch code works. But when I execute my application exe, the try catch code does not work. And unhandled exception message is shown and says to handle SqlException exception. I really get confused what to do...
My code in visual studio running mode, works but when executing the exe file, it does not work. I think it is the worst error for programmers.
Please help me with my stupid problem.
Thanks

Hello All!
I have a richtextbox such that the user can copy-paste images into it. Now i am saving the 'rtf' of richtextbox in the database. Now after retrieving the 'rtf' and assigning it to Richtextbox, the image doesnt show up.
It is to be noted that the rtf before storing and after retrieving is the same.
Thanx in advance

Hi!
From time to time visual studio 2005 shows a queer error message:
'Code generation for property 'Cursor' failed. Error was: ''CursorConverter' is unable to convert 'System.Windows.Forms.Cursor' to 'System.ComponentModel.Design.Serialization.InstanceDescriptor'.'
Maybe it happens because i use an own UserControl. But in fact this UserControl doesn't make anything with the property cursor ... 
Is there anybody who knows this error message and can say what's wrong!?!?
Thanks in advance!

As far as I can tell, this seems to be a bug in Visual Studio (still present in VS 2008).
A workaround that worked for me was to mark the property with an attribute to make it invisible
to the designer, as follows:
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public Cursor MyCursor{ get; set; }
