I just figured out that .Anchor property.
Those MS guys think of everything :/
That's what ya mean, right?
Thanks!

I'm in the middle of a Windows Forms application with a bunch of TextBoxes. Regular key presses fire KeyUp, KeyPress and KeyDown events. But the Delete key doesn't fire KeyPress. Why? I need to get the text BEFORE it's changed, so I'm trapping it in KeyPress, but when I press the Delete Key, this event doesn't fire. Can someone help? What am I missing here...
TIA
Mark.

I would override IsInputKey(Keys keydata) just to know if the delete key is trapped there. (Keys.Delete = 0x2E).
|
|
|
|
|
I was not able to override IsInputKey or IsInputChar. As far as I could tell, my code was never called.
While developing an Explorer Bar in C#, using the BandObject control, the Backspace seems to be ignored -- it is never passed on to the textbox which is a child of my Explorer Bar. A KeyPress event is never triggered for the Backspace key.
What is a good solution? I've heard that trapping the key in TranslateAcceleratorIO is the way to go, which makes sense, but I don't know what to do from there. I wouldn't mind firing an event from there, but how do I fire the event with the right event source? Or is there something I can override to prevent the Backspace key from being trapped?
Thanks,
Arun

Anyone know of any good articles on the design of modular apps, apps that can utilise plug-ins for example. In the style of winamp's plugins. Such that supplement to distribution, new features can be added to the app without having to re-build the app itself.

THe .NET reflection API opens the door of a new generation of open apps that can guess entry points of plug-ins, at run-time. I believe the MSDN mag has a few articles about it.
If your plugins are supposed to implement a simple interface, then there is no nothing particularly new or odd with assemblies. They work like dlls.
Plugins can be declared either in the application .config file, or dynamically loaded at run-time by code( System.AppDomain.Load(...) ).

Any particular keywords I should search for? I've tried 'modular applications' and 'plugins'.
Its the principle of, there is an app that knows everything it needs to to run, but then I wanna add a dialog box/form that does something else say a media player or something. I'd need it to add a menu/toolbar item in the main app, then that would load the form (contained in the plugin dll).

I would recommend these 2 MSDN mag articles as a starting point : Dino Esposito Xml plugins[^] ; Paul Di Lascia Xml GUIs[^].

Hey I told you it was bloody annoying, and I was bored when I made it.
It was designed to be the most annoying app ever. Next to Clippy.

Hi all,
I want to build in c# a persistant activex containing 4 ocx : ocx1, ocx2, ocx3, ocx4. To catch ocx events, we must embedd them in forms.
So, my c# activex will be an activex containing :
4 forms for my 4 ocx.
The goal is :
- The c# activex is an "OCX WRAPPER" exposing an interface allowing
to invoke all the methods of the 4 ocx. When a process invoke a method of this wrapper, the wrapper switch to the good ocx.
- There is only one instance of each ocx
- We must be able to invoke a method of an embedded ocx in a process
and catch an event in another process !
Good luck.

Sounds like event dispatching (all 4 ocxs are event sources and event sinks at the same time).

Sounds like mutex

Events cross the process boundaries. Not an issue here.

Good homework, indeed. 
(well at least, if you like plumbering and marshaling).

I am trying to draw graphics on media player,It works. but when I play a movie, the draw the graphics has been hidden on the movie. and i can not draw on the media player anymore, but if i draw on the brink, still can see some line of graphics.
It is said that bcs media player is Weight object, they always hides light object. any body know these concept?
How can i do if i want to draw on the movie. is there any setting i need to do or whatever....
pls help.
thanks a lot

Not sure about the latest Windows media player SDK, but the apps I have seen in the past rely on DirectShow (DirectX SDK), draw in a doublebuffer, and blit the resulting stuff on screen.

I did not catch what u mean, how do u think the solution of the problem?
i want to draw on mediaplayer,but it is weight object. how should i do?

I am trying to send email with an encrypted xml document attached to it. The file is writen to a log then picked up encrypted using the System.Security.Cryptography namespace and then attached to an email. When I receive the mail and decrypt the attachment, 1 out of ten will have the last few letters of the closing tag is missing. The path that the file takes is as follows.
1.Encrypted using RijndaelManaged Algorithm
2.attached to the email as a MIME Entity and encoded in base64
3.received in the email client and converted from base64 to a byte array of the attachment.
4.decrypt with RijndaelManaged Algorithm.
The kicker is that when I don't encrypt the file with RijndaelManaged the files are all recieved in full and when I encrypt and decrypt without send in files by email the encrypted matches the decrypted file. however, when I do both together I lose data in 1 of every 10 files.
the following is what the end of a messed up file looks like followed by the xml error it gets when opened.
xml file **********************************************************
<?xml version="1.0" standalone="yes"?>
<diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">

</diffgr:diffgr

thanks in advance for your help.

In order to help you with this, you must post the source code you are using for encryption / decryption. Do that and I'll see what I can do to help.

The following is the source code that I wrote to set up my encryption class. This works independently of the entire program and will successfully encrypt and decrypt any byte array I pass through it. However, when I encrypt a file attach it to an email and then decrypt that file when recieved. I lose the data.
using System;
using System.Security.Cryptography;
using System.IO;
using System.Text;
namespace crypt.Cryptography
{
class SymCryptography
{
private string _Key;
public SymCryptography()
{
}
public string EncryptionKey
{
get
{
return _Key;
}
set
{
_Key = value;
}
}
public byte[] Encrypt(byte[] source)
{
byte[] EncryptedFile= null;
byte[] encryptedKey = this.getKeyBytes();
SymmetricAlgorithm rijn =SymmetricAlgorithm.Create();
//Creates the default implementation, which is
//RijndaelManaged.
MemoryStream encryptContainerMS = new MemoryStream();
CryptoStream encryptStream = new CryptoStream
(encryptContainerMS,rijn.CreateEncryptor(encryptedKey,
encryptedKey),CryptoStreamMode.Write);
encryptStream.Write(source,0,source.Length);
encryptStream.FlushFinalBlock();
encryptStream.Close();
EncryptedFile = encryptContainerMS.ToArray();
return EncryptedFile;
}
private byte[] getKeyBytes()
{
UnicodeEncoding UE = new UnicodeEncoding();
return UE.GetBytes(this._Key);
}
public byte[] Decrypt(byte[] source)
{
byte[] DecryptedFile= null;
byte[] encryptedKey = this.getKeyBytes();
SymmetricAlgorithm rijn= SymmetricAlgorithm.Create();
//Creates the default implementation, which is
// RijndaelManaged.
MemoryStream decryptContainer = new MemoryStream();
CryptoStream decryptStream = new CryptoStream(decryptContainer,
rijn.CreateDecryptor(encryptedKey, encryptedKey),
CryptoStreamMode.Write);
decryptStream.Write(source,0,source.Length);
decryptStream.FlushFinalBlock();
decryptStream.Close();
DecryptedFile = decryptContainer.ToArray();
return DecryptedFile;
}
}
}
thanks for the help.
