Surely you are someone and you are testing the application all the time. Security is not something to be tagged on at the end. It is something that should be in up front at the start or development and stays all the way through to the end.

I use DirectX.AudioVideoPlayback to play video, which require any control to be an "owner" in which it plays video. Now I selected to play video in Panel control & wanted to save snapshot/picture of any paused frame. Thats taking picture from movie.
Tell me how can I do this (please include coding if possible)

AudioVideoPlayback is no longer supported, and won't come out in future versions for .NET 2.0 at least. However, you should be able to render to a texture, which you can then save.

The AudioVideoPlayback namespace is gone. There's nothing new that's good that I know of.

Thats really bad, but I think some other namespace will replace it but it cannot be completely removed.

They are in the SDK, but I also bought a book.

My fear is the new SDK will be WPF, which only runs on XP and higher.

Ok I'll search in the SDK, Please confirm me, you are talking about DirectX SDK?

Thats Microsoft policy to eliminate usage of old versions of Windows.
Tell me what WPF stands for?

It seems that the message tells the story.
Or you set a non null value for bcId or you make it nullable in the DB.

I have a picturebox for view some jpg file.
However, the jpg is always larger than the picture box view.
By default,
<br />
pictureBox.SizeMode = PictureBoxSizeMode.StretchImage<br />
after a button is clicked, it change to
<br />
pictureBox.SizeMode = PictureBoxSizeMode.Normal<br />
How can I view the whole 1:1 picture by the control of verticle and horizontal scrolling bar?
Any example/article for this?
Thank you!

Hi,
I am new to VB .Net so was going thru this e-book. I came across an error which I was unabe to understand. Even writing to their customer support didn't help and they referred me to the author who hasn't replied back for past 2 months. here is the description of the problem
e-Book : Mastering VB .Net
Author : Evangelos Petroutsos
Page Number : 112
Lines In Concern : 15 to 21
Specific Line : 20
Structure Person - Line 15
Dim First As String - Line 16
Dim Last As String - Line 17
Dim Address As String - Line 18
Dim Phone As String - Line 19
Dim EMail(10) As String - Line 20
End Structure - Line 21
My Operating System : Microsoft Windows 2000 5.00.2195
Service Pack 4
IDE : Microsoft Visual Studio .NET 2003
Error Text : "Arrays Declared as structure members cannot be
declared with an intial size"
Problem Description : The code was copied 'AS IT IS' From the book and
The declaration given in the 20th line on the
112th page, where an Array of index 10 is declared
inside the structure, generated the above quoted
error. Please explain the reason for the
occurance of the error.
|
|

The reason it fails is because you can't initialize a structure's members variables upon declaration. This is only allowed in a class. For example, the following is not allowed in a structure...
Public Structure Person
Public Age As Integer = 21 ' Error!
Public Name As String = "Bob" ' Error!
Public Age As New Date(1970, 1, 1) ' Error!
End Structure
Now, how is this related to your array you ask? It's because the following array declaration...
Dim Numbers(2) As Integer
...creates a new array object and is not all that different than declaring it like this...
Dim Numbers() As Integer = New Integer() {0, 0, 0}
So, what can you do about it? You can create an initialization function that will allocate the array for you. Or you can initialize it in a constructor, but remember that a structure can't have a constructor with no arguments.
I hope this helps!

Hey,
Thanks for taking time to reply to this one.
Yes I do understand and I hope this is the only explanation.
It is not the same in other languages that I know, Example this kind of error does not occut in C or maybe even C++. Still it was a great help.
But I still cannot understand why it was gievn in that book, when the code is generating errors.
Anyways
Thanks a lot
Love
