Hi,
Modifier internal means that we can only access that class from the same assembly.
"protected internal" cannot be applied on class. But it can be applied on members. This means two things. It is either derived classes or classes in the same file that can access that member.

It can if the class is nested within another class.

I have a C# app that wraps windows media player to play some streaming audio. I need a way to determine the sound level of the stream (Not the volume level that media player is set to). Any one know how to do this?

Hello everybody,
I hope someone will be able to help me with something I have come across.
What I want to do is to recognize a specific object in a picture. I will process the image and we will suppose that the image is taken from the same distance at a certain interval of time (let's say with a webcam).
Now, what I have done is extracted all the objects from an image using Andrew Kirillov's Image Processing Lab (it can be found here on codeproject). However, the Image Processing Lab extracts Blobs, which are formed of the object I am interested and it is placed in a rectangle.
What I want to do is to extract ONLY the object and I have no clue on how to do that. Does anyone have any ideas ?
After that I want to compare that object with another one extracted from another picture.
Is there a way of comparing two pictures and searching for a certain object?
I guess I am looking for a simple shape recognition algorithm.
Please guide me on this,
Thank you very much,
OviDeus

Short and skinny version.
I am creating a application that will copy files from one location to another. There will be an option that allows the user to automatically delete the destination folder after a specified number of days. Before implementing this functionality I have been trying to delete the directory by hard coding the destination path. But each time I do only the files are deleted and the folders are left behind and I'm left with a IOException, telling me that access to the specified path is denied.
Any thoughts?
Freedom is the right to say that 2+2=5 if this is so everything else will follow.

There is an overloaded .Delete method that allows you to delete all subdirectories as well.
|
|
|
|
|
I have set the recursive to true:
DirectoryInfo asdf = new DirectoryInfo(temp.getDestination());
try
{
asdf.Delete(true);
}
catch(IOException d)
{
MessageBox.Show(d.ToString());
}
The folder that I am trying to delete contains a folder, which contains another folder, which contains another folder, which contains 12 files. The 12 files get deleted but the folder that contains the 12 files is the folder that the exception says access is denied on.

Hi,
Try to delete the folder using "DirectoryInfo.Delete(true)" function. Please note that you need to provide the parameter as "true" so that even if there are files and sub-folder in that particular folder, they all will get deleted.

I have tried this.
Thanks for the suggestion though. I just don't get why something so simple is causing me so much hassle.
The folders that I am trying to delete have been copied by my application.

Try checking if any of the files in the folder are left open.
|
|
|
|
|
Got it!
Nothing to do with open files or folders.
When I was copying form on the source to the destination I needed to specify Access Control:
if (!Directory.Exists(Dst))
{
Directory.CreateDirectory(Dst);
System.Security.AccessControl.DirectorySecurity asdf = new System.Security.AccessControl.DirectorySecurity(Dst, System.Security.AccessControl.AccessControlSections.All);
}

then are you sure that the directories/files aren't Read Only or being used by another application?
That's always the first thing that comes to my mind whenever something tells me access to a file is denied.

Have you researched Click Once? There is plenty of information about it, books even.

I've got a stringbuilder object back from a dll for which i don't have the source by using an API call. The api call is a blackbox I have no idea what happens inside it.
Inspecting the stringbuilder in VS shows the same result as inspecting the output in the VB6 app i am trying to copy.
I now need to perform a bitwise mask on each of the bytes in the stringbuilder as that is what the original app does.
How can i get a byte array of ASCII values out of a string builder?
I've tried these 2 approaches:
Encoding enc = Encoding.ASCII;
byte[] bytes = enc.GetBytes(text.ToString());
This overflows value bigger than unsigned byte...
for (int i = 0; i < text.Length; i++)
{
Console.WriteLine(text[i] + " " + Convert.ToByte(text[i]));
}
this produces output that doesn't seem to bear much relation to the input data.

Console.WriteLine(text[i] + " " + Convert.ToByte(text[i]));<br />

Has anyone played with string compatability between VB6 and c#?

WHat does? I see nothing wrong with you use of Encoding.ASCII.GetBytes(string) it works fine for me.

sorry, it doesn't look like it did when i typed it. That comment should have been attached to the code below it. The ASCII encode was giving me values that weren't the same as the old skool VB6 Asc command. (oops no i've attached the wrong comment to each piee of code)
I've used the Microsoft.VisualBasic.Strings.Asc function now and i'm getting the results i need.
Thanks for the reply.

ASP.NET 2.0 is better
nullable types
anonymous methods ( although these are not so great, and have potential for misuse )
