You can make use of role based security in your application. Have a predefined set of roles. Assign them the rights as needed. Then assign each user to a particular role.
This[^] might help.

Hi Danish
Can you give me some more detail about role based security.
For example, how to define the roles and how to link for example the buttons to these roles?
What I see as most difficult is how to intermix the enabling and disabling of buttons and menu options depending on the security roles in combination with the "normal" button enabling and disabling business logic.

When you are authenticating the user, at that point of time you should check the role the user belongs to. Once you get the role, enable/disable the controls. As far as enabling disable of the controls based on the business rules goes, that would happen on some user action after he logs in. So that would not interfere.
Here[^] is another article that might be useful.

I want know how to keep records of copied files to an external disk,such as USB? does anyone know how to achieve this in coding? Which kind of API s can we used to do this?
|

you could use log4net and log either to a file or a database everytime you do a copy ...
is that the sort of thing you mean ?

There's no filter or event that fires for all copy-actions.
Do you want to log copy-actions initiated by your own application? If so, you'd need to write a message yourself.
Do you want to keep an eye on a folder on that external drive? A FileSystemWatcher perhaps?
Can you explain in more detail what it is that you're trying to achieve?

I want to keep and eye on all the files that are copying to a USB media. Whenever file copy operation perform, I want to check whether those are copying a USB device or not. If they are copying to a USB device, details of those file transfers should be logged.

Might be doable using a CopyHook[^].

Hi,
You have to write a service which will motinor USB drive. If any USB is connected to the system than watch that USB using FileWatcher class.

I think you are right. But is there any examples how to achieve this. And I'm not that much sure whether I can do this for file copy event using FileSystemWatcher.

I apologize if this post is generic and redundant, but I have not found a solution, but I have been searching the net for a good example with no luck....
I have a simple windows form app that has a windows media control, and I want to play a playlist. I have a directory that has a list of playlists and I want to select a playlist and play it.
I have all the code to select the playlist working, but I can not for the life of me figure how to set the active playlist in the control and then make it play...
Any links or direction to a place find a sample would be greatly appreciated.

I have to agree that information on this does seem hard to come by.
For all comments that follow I am assuming that you are talking about the WindowsMediaPlayer ActiveX control, although your question does not make it clear. If it is not this control, please let me know to save me wasting my time.
However after about 10 minutes Googling I have discovered that there is a currentPlaylist property, so far, however I am unable to determine how to start playing.
Unless you tell me that it is not WMP control I will continue investigating.

I have just found this[^] thread which contains
this.axWindowsMediaPlayer1.Stop();
so maybe there is a
this.axWindowsMediaPlayer1.Start();
method? Give it a try, the worst that can happen is that your computer will explode!

OK, here is the full gen.
Go to Solution explorer.
Open the references folder.
Find the reference to the DLL you are using and right-click on it.
From the context menu select 'View in Object Explorer'.
In the left-hand pane of the Object Explorer scroll down to and select WindowsMediaPlayerClass.
In the top right-hand pane you will see all of the available members.
You will see that there is a Play method, it would seem to be what you are looking for.
Whilst you are there, have a good look through the list, there are lots of useful looking methods/properties.

I am sorry I did not post the control, but yes your assumption is correct I am using the windows media player control.
I will post with the end result, and a code snippet in case helps others, thanks for the pointers.

Hi,
this recent article[^] presents a simple way to log information; it does not rely on Windows Event Viewer stuff though.
CodeProject hosts a number of articles dealing with Windows Events and Event Viewer, here[^] is just one of them.

You have System.Diagnostics.Trace and log4net framework.Just google and will find plenty of articles & tutorials how to use them.

Hello everyone,
I have a bitmap object that is created in C# and I want to share this bitmap between managed and unmanaged code.
So, I have something as follows in my C# code:
void DrawGraphic()
{
BitmapData bitmapData = myBitmap.LockBits(new Rectangle(0, 0, Width, Height), ImageLockMode.ReadWrite,
PixelFormat.Format32bppArgb);
}
Is there a possibility to pass the BitmapData pointer to my unmanaged code and then use the result? So, I do not want to create a copy but somehow share this bitmap data.
Thanks for any help you can give me.
Thanks,
Keith
