No, you do not need to register the DLLs (the only assemblies you would register are those that contain CCWs, or COM-Callable Wrappers - the interop assemblies you're using are RCW, or Runtime-Callable Wrappers, to COM servers already registered).

Instead of create the interop assemblies yourself, use the PIAs (Primary Interop Assemblies) from Microsoft - the official assemblies created by them. You can download them for Office XP (just search for Office PIAs on http://msdn.microsoft.com[^]) or install them with Office 2003 Professional as ".NET Framework Support" or something like that.

Make sure that these assemblies are either deployed to the same directory as the assemblies you've created (and pay attention to code access security policies if they're not running on the local machine), or install them into the GAC (Global Assembly Cache) using gacutil.exe, ngen.exe (also pre-JITs the IL), drag and drop them to %WINDIR%\assembly, or using an installer like Windows Installer (for which VS.NET has basic installer projects).

Thanks for the advice, I just about managed to follow it all! (maybe one day i'll increase from newbie status!) The version of office I am using is 2000, so I can't go down the PIA route. I think i'll create an installer for the app as I don't have direct access to the machine, it's an end user performing the install.

See PrintDocument class in MSDN and there is an exmaple of printing there. In the PrintPage event use DrawImage instead of DrawString in that example.

Encrypting text data to a file

I was wondering what would be the best way to encrypt text data to a file. At the moment, I am basically serializing my class object that holds all the data, and storing the data via a BinaryFormatter (to a text file).

I was just wondering if there would be a better way to do this?

Here is my code:

Stream stream = File.Open( filePathString, FileMode.Create );
BinaryFormatter bformatter = new BinaryFormatter();
bformatter.Serialize(stream, Organizer.activeProfile); //activeProfile is my object
stream.Close();

Thanks in advance,
Jon

GUI design the way forward for MS

14-Apr-04 4:30

If you want to encrypt it, use the System.Security.Cryptography classes. You can chain whatever encryption method you want with the ToBase64Transform class to output base64-encoded data (most common) to a text file. Read the class documentation for various classes. There's a lot of example code.

I am involved in the redesign of a large project which is expected to take approx 5 years to complete. I need to find out (if possible) where MS GUI designs are going, i.e. what Microsoft intend to do with their GUI's will they be sticking with Office 2003 theme?

Can someone guide me to a suitable URL where I can read up on where MS are going with their GUI designs.

The Office 2003 scheme? Every Office has introduced a new scheme which has pretty much set the standard for products until the next Office is released. With a release schedule 5 years away (at least), basing your product on Office is probably not a good idea. Just go with the typical flat style which is still the basic scheme of the newer variants.

Another option is to use a third-party library that keeps up-to-date with the Office scheme. Even before the new Office comes out, the company should update their UI and release new assemblies, which - if they are backward compatible - you could simply add a publisher policy to the GAC or using binding redirection in your app's .config file to use the new versions even without recompiling (if it's already deployed, for example, and isn't ready for a rebuild). That'd probably be your best option, unless you want to maintain your own UI toolkit in a similar fashion. Just make it as abstract as possible, perhaps even supporting whatever theme a user wants.

Maybe you can find more info if you look about Longhorn and the technology "Avalon" you can find an articule in http://techzone.pcvsconsole.com/news.php?tzd=2168[^]

5 years down the road we may very well be using Avalon instead of System.Windows.Forms. Poke tongue | ;-P

That would pretty much throw away all your UI work.

Longhorn and Avalon[^] is the way MS are going. However they still haven't released any information about the actual look and feel of the new presentation layer.

It might be worth looking into using something like MyXaml[^] as this will help keep your presentation layer seperate from the rest of your application logic. Allowing you to change the UI without having to recompile your application code.

If i have a xmldocument like this:

<?xml version="1.0" standalone="yes"?>
<sessions version="1.0">
<session name="Development">
<parameters>
<developmentsession>true</developmentsession>
<rootdirectory>n:\realsoftware</rootdirectory>
<debuglevel>1</debuglevel>
</parameters>
</session>
<session name="AppserverDevelopment">
<parameters>
<developmentsession>true</developmentsession>
<rootdirectory>f:\pro.net\realsoftware</rootdirectory>
<debuglevel>1</debuglevel>
</parameters>
</session>
</sessions>

And if i do this in the code section:

private void cboSessions_SelectedIndexChanged_1(object sender, System.EventArgs e)
{
ds.Clear();
string pad = "//session[@name='" + cboSessions.SelectedItem.ToString() + "']";
XmlDocument xml = new XmlDocument();
xml.Load(@"c:\kopie van sessions.conf.xml")
XmlNodeList contactNodes = xml.SelectNodes(pad);

string box = contactNodes.Item(0).OuterXml;
xml.LoadXml(box);
XmlTextWriter xmltw = new XmlTextWriter(@"c:\testnodes.xml",new UTF8Encoding(false));
xml.WriteTo(xmltw);
xmltw.Close();

ds.ReadXml(@"c:\testnodes.xml");
this.chkDevelopment.DataBindings.Add("Checked", ds.Tables["parameters"].DefaultView, "developmentsession");
}

Now i have a form with the combobox and the check and textboxes. If i do it with this code, he shows it correctly but when i click my combobox again he says there is a mistake:

An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dll
Additional information: This would cause two bindings in the collection to bind to the same property.

What can i do about this? I want to be able to switch between the sessions and make changes to them.

thx in advance

Be sure to remove any existing binding on the Checked before adding a new one.

Casting problem

bouli14-Apr-04 2:32

14-Apr-04 2:32

Hi C# gurus,

I have a casting problem in the following set of classes:

<br />
class Polymino<br />
{<br />
  ...<br />
}<br />
<br />
class Tetramino : Polymino<br />
{<br />
  ...<br />
}<br />
<br />
class ITetramino : Tetramino<br />
{<br />
  ...<br />
}<br />
<br />
class GameBoard<br />
{<br />
  ...<br />
  private Polymino m_polymino;<br />
  ...<br />
<br />
  public Polymino polymino<br />
  {<br />
    get { return m_polymino; }<br />
    set { m_polymino=value; }<br />
  }<br />
  ...<br />
}<br />
<br />
class Tetrion : UserControl<br />
{<br />
  ...<br />
  private GameBoard m_gameBoard;<br />
  ...<br />
  private Tetramino m_currentTetramino;<br />
  ...<br />
<br />
  public void Start()<br />
  {<br />
    m_currentTetramino=GetRandomTetramino();<br />
    m_gameBoard.polymino=m_currentTetramino;<br />
  }<br />
  ...<br />
<br />
  private Tetramino GetRandomTetramino() ...<br />
}<br />

Polymino is the base class of all.
In the Tetrion.Start method, when I call m_gameBoard.polymino=m_currentTetramino, I have an error in the m_gameBoard.polymino property call. I guess it's a casting problem. In C++ this kind of thinking is okay, but it seems that it does not work in C#, even if I do a cast like that: m_gameBoard.polymino=(Polymino) m_currentTetramino.

Can anybody help me and tell me why the debugger stops at this call?

Best regards.
Thanks.

What is the exact exception you are receiving, including the Type and message (if any)?

Hi Heath,

I have no exception... The call stack is full of "Tetour.exe!Tetour.GameBoard.set_polymino(Tetour.Polymino value = {Tetour.STetramino}) Line 49 + 0xa bytes"
STetramino is derived from Tetramino which is derived from Polymino. as STetramino is a specialized class based on Polymino class, the casting should work... like for C++... Confused | :confused:

Heath Stewart14-Apr-04 2:59

Yes it should, just like the ArrayList which collects objects can take an instance of any class no matter far down the derivation tree it is.

Are these simple classes or controls (or possibly modify control properties directly)? If so, are you using multiple threads? Odd problems can occur when getting and most often setting properties on controls from another thread besides the main UI thread.

What causes the break into the debugger if you're not seeing an exception? Are you just stepping through lines or does it break while executing?

it breaks while executing.

All the classes I show you are simple classes. the only classes derived from a UserControl are the Tetrion and TetraminoPreview classes.

The complete code of Tetrion.Start() method looks like this:

<br />
		public void Start()<br />
		{<br />
			Debug.WriteLine("Tetrion.Start");<br />
			m_gameStatus=GameStatus.gameStarted;<br />
			m_gameBoard.Initialize();<br />
<br />
			m_currentTetramino=GetRandomTetramino();<br />
			m_gameBoard.polymino=m_currentTetramino;<br />
			m_nextTetramino=GetRandomTetramino();<br />
<br />
			if (m_tetraminoView != null)<br />
			{<br />
				m_tetraminoView.tetramino=m_nextTetramino;<br />
				m_tetraminoView.Display=m_bShowNextTetramino;<br />
				m_tetraminoView.Draw3D=m_gameBoard.Draw3D;<br />
				m_tetraminoView.DrawGrid=m_gameBoard.DrawGrid;<br />
			}<br />
			<br />
			Invalidate();<br />
		}<br />
<br />

The code stops its execution at the call m_gameBoard.polymino=m_currentTetramino;
while there are no break points. Confused | :confused:

There is no spoon.

you were right. the exception is:
"An unhandled exception of type 'System.StackOverflowException' occurred in Tetour.exe"
