As I mentioned with one of your earlier questions, an ActiveX control contains it's own message queue and .NET has no control over that. If there are events exposed on the ActiveX control, those should be declared by the RCW (Runtime Callable Wrapper) and you can use those. If it doesn't have them, there's really nothing you can do. This is not a .NET Control, merely an ActiveX control hosted within a .NET Control that does little more than marshal calls from managed to unmanaged code.

please help more.how can i access to RCW .and please a tell me address of related sample .

The very use of the Acrobat control means that you are already using the RCW. What I was saying was that the ActiveX control has to expose some interfaces that let you handle notification messages. The AxHost control merely hosts the ActiveX control. Messages passed through the message pump are not handled by the window procedure (WndProc ) for the control in the same manner that other controls' messages are handled.
For instance, if you host the WebBrowser control you can modify the AxHost -derived slightly and pass a number of interfaces to the WebBrowser control. I haven't ever needed to try this with the Acrobat ActiveX control (it would be different interfaces, if any) so I don't know if it support this. I do know that it does support ActiveX Containers, but that is beyond the scope of a simple message board.
I recommend you go to Adobe's web site[^] and look for developer information, or search the 'net with google or something. For more information on ActiveX containers, see the MSDN Library Online[^]. It's not a simple solution.

how i serialize userControl BackGroundimage?
i wanted import windows media but i cant rigthclick and doubleclick it.
i want doubleclick in AxmediaPlayer and then open another form that select opened file.
thus i create a usercontrol and hide Axmediaplayer and then size of usercontrol put in size of windows media and show AxmediaPLayer.
now i want serialize and deserializ AxmediaPlayer but I dont Know
what i do?
thanks

I just answered your question before: you don't need to serialize the media player control at all. You're not sending it across context boundaries (separate AppDomains, separate processes, separate machines, etc.), so there's no reason to serialize it in order to marshal it. Either re-parent the control or use the existing methods from the PlayerApplication class I mentioned before.
You won't be able to recieve single- and double-click events from the AxMediaPlayer control as you would with other Windows Forms control because the AxMediaPlayer control is an ActiveX control with it's own thread queue (message dispatch). If the control exposes appropriate events, you can handle those, but the Click and DoubleClick events you find on other controls will not work.
See my previous post for details about re-parenting the control or using the supplied methods exposed by its typelib that you use to create an interop assembly, which I also gave you instructions on. If you don't understand them, continue the thread - don't start a new one.

thanks for your help
i want a form with some controls for example textbox,picturebox,shape,Axmediaplayer,and Axshockwaveflash
and i want to save as that form with total controls,with xml format, and load that form too.

That's a different request than from before. In the future, please be as descriptive as you can when describing a problem - in anything you do (not just development; like to doctors, lawyers, etc.).
Images can't be serialized using XML Serialization, unless you were to attribute your non-supported properties with your own implementation of TypeConverter s that could effectively convert to and from strings (like for an image, you could serialize as a base64-encoded string using the ToBase64Transform class, for example). That's really about the only thing you can do; either that, or go to a lot more trouble of using Runtime Serialization with a SOAP (an XML dialect) formatter since all your control classes are themselves serializable (which means you have to extend every control you use and implement ISerializable .
I recommend you take a look at Marc Clifton's articles here on CodeProject about his project (recognized by Microsoft), http://www.myxaml.com[^]. It already does a lot of this, and you can either learn from his code (which requires pretty in-depth knowledge of the .NET Framework) or simply use it for your UIs.

hi,
is there any command in ADO.NET to list all tables from a given database name?
(in C#)
|
|
|
|
|
ADO.NET is ADO.NET whether you're using C#, VB.NET, MC++, etc. In fact, all assemblies work the same in any managed language. It's important to understand that.
That being said, ADO.NET is an abstract interface to any database driver that uses either an OLE DB driver, ODBC driver, or has implemented a specific driver client implementing the ADO.NET interfaces. That does not mean, however, that every feature in a particular database is supported, since abstraction leads to simplification (which is why SQL Server, Oracle, and others have implemented their own clients for ADO.NET).
Enumerating databases in a DBMS is different; so, what type of DBMS do you want to enumerate?
In SQL Server, you can use the "sp_helpdb" stored procedure. For Access, there is no way other than searching your hard drive for *.mdb, since Access uses Jet Databases, which is a file-based database. It's different for MySQL, Oracle, and others, too.

in mysql, i can use 'show tables' command to list down all the tables in particular database.
i wanna know how to do this in sql server 2000.
so that i can use C# to perform such operation using data adapter
|

There's several ways you can show tables in SQL Server, the easiest being the INFORMATION_SCHEMA metadata table:
SELECT table_name
FROM INFORMATION_SCHEMA.TABLES You can also query the sysobjects table:
SELECT name
FROM sysobjects
WHERE xtype = 'U' or xtype = 'S' -- U for user tables, S for system tables

Hi
please tell me what exactly the
System.Drawing.Drawing2D.Matrix class and it's operations like
Clone(),Invert(),TransformPoints(points) performs?
Thanks

System.Drawing.Drawing2D.Matrix
Encapsulates a 3-by-3 affine matrix that represents a geometric transform. This class cannot be inherited.
Royaeh kohestan wrote:
Clone()
Creates an exact copy of this Matrix object.
Royaeh kohestan wrote:
Invert()
Inverts this Matrix object, if it is invertible.
Royaeh kohestan wrote:
TransformPoints(points)
Overloaded. Applies the geometric transform this Matrix object represents to an array of points.
That is how it is stated in MSDN. You can find more information here[^]. Hope this helps you out.
Happy Programming and God Bless!

thanks Dear bneacetp,
i read this explanations before,but i can't have a good conception of them,
can your self give more explanation with one example of its structure and elements?

it seems your asking not on the class itself, but about matrix manipulations. this is usualy referred to in basic linear algebra courses. you can easily find links such as:
http://www.isr.umd.edu/~austin/aladdin.html#sec3[^]
anyway, the basic idea is that you can do arithmetics with matrices (and vectors), in a way that somewhat resembles number (scalar) arithmetics. These arithmetics can have functional and gerometrical meanings.

Oh come on - it's all in the .NET Framework SDK which you should already have installed! Look it up in the documentation. how do you expect to learn anything?!

Then you really should be a little more specific in your question. Asking what they do when the .NET Framework SDK class documentation for the Matrix clearly states what they is asking for trouble.
If you don't understand matrix calculations - because, frankly, the method names are self-explanitory even without reading the documentatin - I suggest you do a google search on matrix operations[^], or something similar.
This forum is for programming questions, and while a basic understand of matrix operations may lead to questions asking how to use it, your questions really seem along the lines of basic matrix operation questions. This is a class all by itself.
