Hi all,
Sorry for putting up the two silly questions (named Drawing on a Form & Drawing on an image).....
Jumped the gun and submitted it.
The problem was simple. The DrawString wasn't working because i had put that statement in the Load event handler method. The Load event is fired before the form is shown, and the Paint method was reworking and erasing all that i was drawing.
So, there was no need to get the graphics of the image. The form itself did the trick.
Thanks to all for bearing with me.

My copy/paste operation results in a MemoryStream full of '\0' characters on the Clipboard.
Maybe my approach to copy/paste is wrong when handling generic types?
All entries in the CollectionBase are, of course, ISerializable and the binary serialization to file fully works. The collection is, to sketch the context, a set of shapes and connections of a diagram (application), see the Netron project[^] for details.
Thank you so much for you help. ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
The copy operation:
CollectionBase<IDiagramEntity> copy = MyDeepCopyOfTheCollectionViaSerialization();
DataFormats.Format format =
DataFormats.GetFormat(typeof(CollectionBase<IDiagramEntity> ).FullName);
IDataObject dataObject = new DataObject();
dataObject.SetData(format.Name, false, copy);
Clipboard.SetDataObject(dataObject, false);
where the MyDeepCopyOfTheCollectionViaSerialization() is :
CollectionBase<T> newobj = null;
MemoryStream stream = new MemoryStream();
GenericFormatter<BinaryFormatter> f = new
GenericFormatter<BinaryFormatter>();
f.Serialize(stream, this);
stream.Seek(0, SeekOrigin.Begin);
newobj = f.Deserialize<CollectionBase<T>>(stream);
stream.Close();
return newobj;
And finally the Paste operation is:
IDataObject data = Clipboard.GetDataObject();
string format = typeof(CollectionBase<IDiagramEntity> ).FullName;
if (data.GetDataPresent(format))
{
}

What on earth you doing there?
Why not pass the just generated memorystream directly?

Ah! Interesting, though unorthodox idea. The logic is as follows; I first make a deep copy of the collection such that it's detached from the context. Since it's a copy of the collection is seemed logical to implement a 'Copy()' method. Of course, your suggestion is quite an interesting short-cut and I tried it out but...a Stream instance is not serializable and the pasting results in a 'null' value. On the other hand, an Image object is a kind of stream as well, no? 
The Clipboard has never been my favorite.
Thanks a bunch for the idea! I have posted the question on Google, MSDN forums, here and you're the only one who has answered.

I have tried something similar, and as long as you remain with an application, rather use a static hashtable and map objects to GUID's or something. In my case I want to keep the proper uncloned references.

You know what...it's working. It seems things like
stream.Seek(0, SeekOrigin.Begin);
are not a good idea. Thanks!
By the way, your XACC project is really impressive.

Hi!
I want to stream mp3 files from my home computer over the internet.
I want to be able to have a webpage on my computer where I can manipulate the playlist, choose next song, previous etc.
I would in other words need a live feed and I want to be able to stream different songs to different users.
Any ideas how this can be done?

I dont think that you need to reinvent the wheel and try to stream the media yourself.
Use Windows Media Server as backend to host the media files and use either an asp page or any other custom application as front end.

With Media Server, you can have your own songs playing in a playlist, which could be streamed over the internet. Also, you can have on-demand streaming.
dennisss80 wrote: I want to be able to have a webpage on my computer where I can manipulate the playlist, choose next song, previous etc.
So, all you got to do on the client side, is to use the Media Player ActiveX control to play the song.
Making a playlist is the logic that should be done by you. Something like, let the users choose the songs. Then you iterate through each song name and get it streamed as an on-demand streaming.
That all should do the trick.
Good Luck.

You might want to check with your ISP's Terms Of Service before you even try to set this up. Most ISP's, like Comcast, don't allow you to setup servers inside their network. But some do...

This will be a bunch of code on your part. You'll not only have to expose the Windows Media Server, but also a Web Server.

How much upstream bandwidth do you have???? You may have 6Mb downstream, and only 128Kb to 512Kb up. Most people don't have the upstream bandwidth to support for more than about 3 people with any decent quality.

Thank you both for your answers.
Isn't just WMS for windows server os?
I can't set up a server at home without killing my non existent economy

Use .PadRight()
foreach(Int32[] cells in rows) {
sw.Write(" ");
sw.Write(cells[0].ToString().PadRight(14, ' ');
sw.Write(cells[1].ToString().PadRight(9, ' ');
sw.WriteLine(cells[2].ToString());
}
Share and enjoy.

Try this creating your graphics object like this:
Graphics gfx = Graphics.FromImage(img);<br />
Where img is the image you want to draw on
Then you can use gfx to draw on the image.

I thy to change lifetime mode of ordinary registered singleton to "live forever".
Try this:
----------------
public override object InitializeLifetimeService()
{ ILease lease = (ILease)base.InitializeLifetimeService();
if (lease.CurrentState == LeaseState.Initial)
{ lease.InitialLeaseTime = TimeSpan.Zero; }
return lease; }
----------------
Or Try this (as reccommended):
----------------
public override object InitializeLifetimeService()
{ return null; }
----------------
But in both cases singleton die after 5 min.
When I try to get it's method I get just this exception:
----------------
System.Runtime.Remoting.RemotingException: Object
has been disconnected or does not exist at the server.
Server stack trace:
at
System.Runtime.Remoting.Channels.ChannelServices.CheckDisconnectedOrCreateWellKnownObject(IMessage msg)
at System.Runtime.Remoting.Channels.ChannelServices.SyncDispatchMessage(IMessage msg)
Exception rethrown at [0]:
at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)
at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
----------------
That means that overriding of InitializeLifetimeService() has no effects!
How can it be possible?
Thanks a lot for any help.

I need to write an application that will open a windows application (platform builder), wait for it to open, give it the focus, and then press a button to attach a device or send keys to the application.
1. Open application
2. Give the application the focus
3. Start the attach device function by sending in keys to the app
4. Parse the debug information until the device is connected.

And your question is ??????

1. quod erat demonstrandum
2. "Give a man a fish and you've fed him for a day. Teach him how to fish and you've fed him for life." I read that somewhere once
(Translation: I'll show you the way, but not write the code for you.)

1. Use Process.Start("");
2. Use SetFocus API
3. Send.SendKeys("");
4. ????

Is it possible to make the size of the array dynamic.
eg:
->here is a part of a recursive function , which extracts the files in a directory and its subdirectories,
->As it is not know the number of files that will be retrieved , i cannot assign a size for the array "files".
foreach(FileInfo b in dirPath )
{
files[ctr]=b.FullName ;
ctr++;
}

No. Use a list instead, like an ArrayList or a HashTable.

b { font-weight: normal; }
