Hello everybody,
By using below codes I produced a pdf file.
static void Main(string[] args)
{
FileStream fstrm=new FileStream("b.pdf", FileMode.OpenOrCreate, FileAccess.ReadWrite);
StreamWriter wrtr = new StreamWriter(fstrm);
string str = "Hello Acrobat";
wrtr.WriteLine(str);
wrtr.Close();
fstrm.Close();
}
However as I open the b.pdf file with Adobe Acrobat 5.0 I see below message.
"Acrobat could not open b.pdf because it is either not a supported file type or because the file has been corrupted."
What should I do to open the file with Acrobat Reader after program?
Thanks a lot.

Write something in PDF format - it's a very complex file format, so you would be best using a third party PDF library like iText[^].

Im writing a windows service in C# and I want to trigger an event within that service using a MS SQl server(2005) Trigger. i.e. The Windows service sits there doing whatever, when a new row is created in a specific table it will somehow message/trigger an event within the service.
Hope this makes sense,. Am I asking in the right place?
Kind Regards,
Rhys

Hi all,
Not a C# or even .net programmer so please bare with me.
Can C# use the Rijendeal/AES block cipher without it beiing imported
from an ASCI file into a keyring?
One of our trading partners is asking to send us files encrypted with
the above cipher. The code they use themselves is show below but I'm
wondering on how & where I'm to store the key values if not on a keyring.
Thanks in advance

{
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
byte[] bytes = encodedsource;
MemoryStream memstream = new MemoryStream();
memstream.Write(bytes, 0, bytes.Length);
memstream.Position = 0;
SymmetricAlgorithm algorithm = SymmetricAlgorithm.Create("RijnDael");
algorithm.Key = key;
algorithm.IV = iv;
ICryptoTransform transform = algorithm.CreateDecryptor();
CryptoStream cryptstream = new CryptoStream(memstream, transform, CryptoStreamMode.Read);
StreamReader reader = new StreamReader(cryptstream);
string returnstring = reader.ReadToEnd();
memstream.Dispose();
reader.Dispose();
cryptstream.Dispose();
return returnstring;

Forgot describe what the keys look like. I've changed the actual vals for this post.
key = ABCDE%^$ABCDE-99
iv = ABCDE$*@ABCDE-99

Thats the issue symmetrical ciphers have.Where does one hide the private key.

You can't do this. You only can change appearence settings in Windows.
Also you can draw scrollbar yourself.
Best regards, Alexey.

Best regards, Alexey.

[LocalizableAttribute(true)] <br />
public string[] Lines { get; set; }
If this property is an Array? How can I add a text to a specific line or read a specific line?
this wont work
this.richTextBox.Lines[2] = "row 3";
|
|
|
|
|
Lines returns a read-only array. You can't set individual elements. However, you can replace the array:
string[] newLines = (string[])(this.richTextBox.Lines.Clone());
newLines[2] = "row 3";
this.richTextBox.Lines = newLines

I've killed again, haven't I?
