I am writing a interface with Managed DirectX. I decided to use their build in UI, CustomUI. For one of the buttons, I have it clear the screen and then I need it to play a AVI file right in the window. I found some code that uses
the DirectX AudioVideoPlayback. The example it showed me did it in windows.forms. Here is the link to the example. The problem is I am tyring to figure out an easy
way to implement this into my CustomUI. I need to give the video ownership,
but I am not sure what window I use to give ownership. And can I do this without having to create a Windows.Forms? Thank help or input would be great.
Thanks.

From experience, Direct3D (which im pretty sure CustomUI is built in) does not like to share sys resources.
I have never used the DirectX AV Playback libraries, but I do know there are lots of posts on other forums like this - maybe you should create two seperate windows, or make a custom designed "flat" button in win.forms?

So it should be possible to create a second window, using the CreateWindow(); method and then use that to host my video playback?
|

Possibly yes, you could use the HWND of the second window to exchange commands between them both.
What are you intending to use the GUI for? If its only simple, then you may want to consider using hotkeys.

The GUI is going to be pretty simple, but I will need to use the mouse. The problem is I don't think I want to create a second window, but figure out how to place the video inside the CustomUI window. I am not sure if I can create a Windows.Form and embedded that into it?

I created an object class derived from System.Object and an array class derived from ArrayList. I'm trying to serialize (and deserialize) the entire thing. I found a great guide here.
When I serialized in the same situation in VC++, it automatically serialized all of the objects in the array for me. All I did was write in private variables that are in the list itself, and all the objects inside the list got serialized properly too.
Now, in C#, I read the file after serialization, it picks up the private array list data but it doesn't automatically serialize the objects inside of it. Not only do they not show up in the resulting file, but there's a breakpoint on the individual object serialization which never gets reached.
The question is, is the array list not supposed to automatically serialize it's objects inside of it, or am I not doing something to let it automatically serialize its members? I can serialize the members using a foreach but I wanted to know what the word on this was so I don't re-invent the wheel.

Did you mark the class inherited from ArrayList with the [Serializable] attribute? As far as I know, serialization cannot be inherited, but I am not sure.

My class that I derived from ArrayList, yeah. I have private variables associated with the list itself that are declared in the lists' class definition like counts, maximums and minimums. Those get serialized and deserialized so I know C# has no problem finding the list.

Could you post the code of the 2 classes, please?

You must put XMLArray and XmlArrayItem attributes as shown in code below:
<br />
[XmlArray ("MyItems"), XmlArrayItem("MyItem", typeof(MyItem))]<br />
public ArrayList MyItems = new ArrayList();<br />
The output XML should be in following form
<MyItems> <br />
<MyItem/><br />
<MyItem/><br />
</MyItems><br />
Of course the MyItem class must be serializable too..

I have to do a heavy load printing job...
In order to be ok with the clients, they want first to preview the printing, analize it, and then print it.
In my implementation I use a printPreviewDialog. When I show the dialog 1-2 minutes are wasted in order to generate the preview - this is OK so far... But when I press on the print button in the dialog, all the data that was readed previously is re-readed again wasting another 1-2 minutes...
Is there a way to print directly the data generated by the printPreviewDialog?
protected internal static readonly ... and I wish the list could continue ...

Hello gurus,
I'd like to know how can I retrieve the previous value of the SelectedIndex of the tab control?
I need to know the previous value before it is modified when the SelectedIndexChanged event of the tab is fired...
Can some one show me a code snipet for doing this please?
Best regards.
Fred.

Why can you not just store the data (int index) in a custom variable?

oops, sorry Leppie, I somehow didnt realise you had already said the same thing lol

Hello,
I would like to store the encrypted password in the Windows Registry, and in my application I want to retrieve the password and decrypt it for further use. How can I achieve this.
Thank you.

Look at the Microsoft.Win32 namespace for registry writing.
Look at the System.Security.Cryptography namespace for encrypting and decrypting data.

I can access Windows Registry no problem. The problem is, I don't know how to store encrypted password in the registry, and when I want to retrieve the password, I need to decrypt the password as well. I figured that I have to use the Cryptograph class, but in what way to encrypt and decrypt the information I can figure out.
Thank you.

So where do you want to store the encryption key in order to decrypt it?
If this is a user password that the user must type in to gain access to something, then using a hashing algorithm is a much better idea. Hashing is a type of one way encryption (you can encrypt, but you cannot decrypt). So when the user types in their password it is also hashed and the two hash values are compared. The bonus is that you don't need to figure out where to store any keys in order to decrypt the data (because you can't decrypt the data)

I would like to store the password in the windows registry, and I want to use the password to access the SQL Server from my Application. So, user will never type in the password. The application will use a generic account to access SQL server and not per user basis. And I want to store the password in the windows registry.
Thank you.
