I know this so far...I must use using System.Runtime.InteropServices; Also, I must say the form class is COM visible like this [ComVisible(true)] .
What I don't understand is how I can call the javascript functions once I have done that. I tried this:
string path = Path.Combine(Path.GetDirectoryName(this.GetType().Assembly.Location), "VirtualEarth.htm");
webBrowser1.Navigate(path);
webBrowser1.Document.InvokeScript("loadMap()");
webBrowser1.Document.InvokeScript("goto_map_position(43.22, 45.56)");
However, all it does it load the intial page. It doesn't appear that the javascript function calls are working. Can anyone provide an example of how to do this.
Many thanks,
chance.

I must be doing something wrong, cuz I am testing out some this mechanism and I make a simple call to a Javascript function like this:
string path = Path.Combine(Path.GetDirectoryName(this.GetType().Assembly.Location), "VirtualEarth.htm");
webBrowser1.Navigate(path);
webBrowser1.Document.InvokeScript("doSomething");
function doSomething()
{
MsgBox("you suck");
map.HideDashboard();
}
Nothing happens.

What does mean 'Internal' and 'Protected Internal' for a class.
Durgesh Kumar Mishra

Internal means the type is only accessible from within the assembly it is defined in.
Protected Internal is simply a combination of the two class modifiers. We know that "internal" means the type can only be accessed from withing the assembly it is defined in. And we know that "protected" means it can only be accessed by the containing class or classed derived from the containing class. So, protected internal means the type can only be accessed by the containing class and derived classes that are included in the same assembly.

protected internal means that the member can be accessed from the current assembly *or* derived classes (both conditions do not need to be true).

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);
}
Freedom is the right to say that 2+2=5 if this is so everything else will follow.

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.
