the thing is it does not just store information on the images, imagine a map class which can hold several tiles, each tile has its own position and size and image, now i need all this information storing one way or another originally i had it storing via binary serialisation but as you know binary serialisation is slow, so i thought about using xml as the users of my program would also be able to edit them and change the values easily
Anyway it does not matter i think referencing the file and the image area(via preset indexes) will do just fine, as i have seen another example which uses this method.

No!

I don't even know what spd is. I certainly did not know that it had a C# implementation.

AFAIK SPD is part of BIOS, so use WMI.

It's cunningly hidden between the info on ISO 8582, and ISO 8584.

And people too stupid to google, probably wouldn't be able to make much sense of it.

Modify file attributes... Access denied.

I am trying to modify the file's attibutes to apply hidden feature. This method appears to be inadequite as it does not change my file attributes. Instead as I run my code and watch what is doing it give me a access denied #5 and invalid parameter #87. What am I doing wrong?

Bitmap bitmap = new Bitmap(1, 1);
                    //string fullPath = string.Format("{0}\\bitmap.bmp", Environment.GetFolderPath(Environment.SpecialFolder.MyPictures));
                    //string fullPath = string.Format("{0}", BMP_Path);
                    bitmap.Save(BMP_Path);
                    if ((File.GetAttributes(BMP_Path) & FileAttributes.Hidden) != FileAttributes.Hidden)
                    {
                        //Adds to the existing file attributes
                        File.SetAttributes(BMP_Path, File.GetAttributes(BMP_Path) | FileAttributes.Hidden);
                        //Replaces the file attributes
                        File.SetAttributes(BMP_Path, File.GetAttributes(BMP_Path) & FileAttributes.Hidden);

                    }

I don't get an error in code. I just do not get my file to become invisible. (Yes I have windows set to hide invisible files and yes I have checked the file at the command prompt to verify the attrib's assigned to the file. It gives no indication that the file is hidden.

In your original post you said:

which is why I asked about errors.

Never mind.

Some of the methods of Bitmap behave in a rather thuggish manner, in that they don't always release files that they have accessed. So I would suggest that you dispose your bitmap before trying the FileAttributes part.

Something like this:

Bitmap bitmap = new Bitmap(1, 1);
//string fullPath = string.Format("{0}\\bitmap.bmp", Environment.GetFolderPath(Environment.SpecialFolder.MyPictures));
//string fullPath = string.Format("{0}", BMP_Path);
bitmap.Save(BMP_Path);
bitmap = null;        //<================================== HERE ********************************
bitmap.Dispose();     //<================================== HERE ********************************
if ((File.GetAttributes(BMP_Path) & FileAttributes.Hidden) != FileAttributes.Hidden)
{
    //Adds to the existing file attributes
    File.SetAttributes(BMP_Path, File.GetAttributes(BMP_Path) | FileAttributes.Hidden);
    //Replaces the file attributes
    File.SetAttributes(BMP_Path, File.GetAttributes(BMP_Path) & FileAttributes.Hidden);
}

I cannot guarantee that this will work, I have not tested it. It is based purely on known behaviour of Bitmap.

I do hope that you only use one of your attribute setting lines at a time, otherwise you cannot tell what is and what is not working.

That worked thanks.
I did only use one in each test. And both lines will result in the same way.

But when disposing the bitmap that fixed it thanks.

C# for Linux

Recently a friend told me that their is a compiler aviable for C# that enables us to generate execuitable for a C# program written in windows to be executed in Linux (i.e. the .cs file written in windows while the execuitable are generated for linux). Is it true? If true which compiler, is it a freeware and where can i find it.

I have also noted that when i open my .cs file in gedit (a text editor) in Ubuntu (a linux based operating system), all the keywords that would high lighted(marked in different color) in VS2K8(Visual Studio 2008) IDE are also high lighted in this text editor. Why is this so?

Yes. Take a look at MONO project. It is open-source.

You'd change the Font[^] of the selection.

Finding class and method definitions in .cs files

Hello everyone!

I'm developing a simple app that would allow me to index .cs files based on classes and methods, for example:
I would like to supply a .cs file and get as a result a list of all classes and methods, related to those classes (including their source and line numbers).

I tried using some regex but was unsuccessful.
Could some one please help me finding the right regex for that, or maybe there is even a better way to accomplish that?

Thanks, Leon.
