i can insert picture from file location but can not use ctrl+v to paste the image.
if (e.Modifiers == Keys.Control && e.KeyCode == Keys.V)
{
DataFormats.Format df;
df = DataFormats.GetFormat(DataFormats.Bitmap);
if (Clipboard.ContainsImage())
{
rtbDoc.Paste(df);
e.Handled = true;
Clipboard.Clear();
}
}

Hi,
Clipboard.GetImage() is required, you can't paste a data format.
BTW: CTRL/V should not clear the Clipboard.

here is the code...
if (e.Modifiers == Keys.Control && e.KeyCode == Keys.V)
{
DataFormats.Format df;
df = DataFormats.GetFormat(DataFormats.Bitmap);
StringCollection strcollect = Clipboard.GetFileDropList();
Image image = Image.FromFile(strcollect[0]);
Clipboard.Clear();
Clipboard.SetImage(image);
if (Clipboard.ContainsImage())
{
rtbDoc.Paste(df);
e.Handled = true;
Clipboard.Clear();
}
}

Hi,
I have a small application that monitors a specified windows folder and displays the activities performed on that folder.My aim is to track all the activities, like creation,renaming,updating files/subfolders under the specified folder, but never allows the user to delete a file or sub folder. I have used FileSystemWatcher(FSW) to track and handles the activities. But Iam not able to track the event that fires just before deletion, and thus not able to deny delete access. My code tracks the activites and informs me of the activities. Please find below the code i have written.I have specified only those part that tracks the folder.The tracking happens on a 'Button Start' click.
<pre>public partial class Frm_Monitor : Form
{
public FileSystemWatcher FileWatcher;
private void Btn_Start_Click(object sender, EventArgs e)
{
FileWatcher = new FileSystemWatcher();
string Path;
Path = txt_FolderPath.Text;//user can browse for the path
//Clear all the previous entry
Tmr_ForThread.Start(); //timer to start the thread
FileWatcher.Path = Path;
FileWatcher.NotifyFilter =
NotifyFilters.FileName | NotifyFilters.Attributes | NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.Security
| NotifyFilters.Size
| NotifyFilters.CreationTime;
FileWatcher.Changed += new FileSystemEventHandler (OnFileEvent);
FileWatcher.Created += new FileSystemEventHandler(OnFileEvent);
FileWatcher.Deleted += new FileSystemEventHandler(OnFileEvent);
FileWatcher.Renamed += new RenamedEventHandler(OnRenameEvent);
FileWatcher.IncludeSubdirectories = true;
FileWatcher.EnableRaisingEvents = true;
}
}</pre>
In the above code, under the 'OnFileEvent' and 'OnRenameEvent', I had written the code to get and pass the 'changetype' and 'fullpath' attribute of the eventhandler arguments to a sub routine. That sub routine uses MethodInvoker on a Listview.BeginInvoke, to display the 'changetype' and 'fullpath' onto a ListView control in the form Frm_Monitor.
Instead of using the FileWatcher.Deleted , what should i use so that I will know the moment the user clicks on deletion of a file/folder, rather than letting me know after the deletion?
Any help in the whole process/idea as soon as possible is much appreciated. Please let me know If i need to paste the whole program

Deleted is in the past tense. If you want to capture something before it happens the events will typically be named in the present continuous/progressive* tense. e.g. Deleting
However, the FileWatcher isn't designed with this in mind. It is simply a mechanism to tell you what changes have been made recently. It cannot tell you what changes are about to be made.
You will have to use low level hooks into the filesystem that are beyond the scope of the .NET Framework to do this.

Thanks for the input. Can u please share with me your knowledge of using filesystem for my issue.

Sorry, my knowledge of the file system no longer extends to the problem that you have. You need someone with low level Win32 API experience. I stopped doing that about 8 years ago.
You are looking at the level that Mark Russinovich deals with. He's the chap that wrote the SysInternals[^] suite of applications. If you can understand that level then you should be able to capture events before they are carried out by trapping them at the OS level. However, be aware, if you get it wrong at that level you could very well destabalise your operating system.

Hey All!  ,
Over the past coupla months I've read alot about TCP/IP and
System.Net.Sockets etc and I made my own little server/client application. Simple. One connects the other listens and receives messages. All works fine on my end (testing). BUT, to my surprise, it never works on anybody elses computer. I give them the client, and I use my server to listen, and they can never end up connecting to my server. They always get a "Server took way way way too long to respond" and similar error messages.  . I tried reading a little more about it and nothing I had read helped solve the problem. So, I turned to my second best friend (Google) and found about 20 sample client/server applications that I downloaded and tested. They all worked perfectly on my own computer. But when I got friends to test, same old story... Couldn't connect. My friends have DSL Internet. Does this matter? Can anybody help shed a little light on this? I'd appreciate any help I can get on this.
lots of thanks,
jay

Are there firewalls in between blocking the connection?
|
|
|
|

Well, I don't know if they are blocking the connection. But now that you've mentioned it. That must be the case since we're all using anti-virus software with their own Firewalls. I use ESET Smart Security. And my friends are using AVG and Norton's. Maybe there's a way to get around the firewall's without disabling them?

If it is a firewall issue, ensure that the port of your service is open on the firewall(s).
You can also cheat and use a common port so long as you are not already using that service. e.g. If you don't have a web server installed on your computer you can use port 80 as firewalls typically keep that one open.

Oh. Awesome. It worked. Thanks so much for that!!!

Hy!
I have multimedia keys on my laptop, just like most of us. These keys make Winamp/iTunis/GOMPlayer and so play/pause, etc. I want to make an application that does just the same: makes multimedia applications play/pause, stop, etc.
Now as these keys work with more applications I suppose (though not sure) that they use a built-in .NET API or some other Windows functionality hidden in some DLL somewhere rather then controlling the hotkeys of the individual applications.
I want my application to be PC model independent, I don't mind having it only Vista compatible.
So can anyone recommend a good starting point, library, class or anything in fact that could get me started. I don't (really) need all of the code to be written for me, I just need something to get me started.
Thanks!

For those who are reading the first post: original introductory sentence was: "I have multimedia keys on my laptop, just like most of us.", hence the discussions. Edited later not to upset all the "sensible" people around here.
And in fact whether you have or not multimedia keys on your keyboard/laptop is not even important as I am looking for a software solution that would make all commonly used media players controllable by software, via OS specific commands (if any) even on system without MM keys.
RESOLVED: Global Mouse and Keyboard Library[^] also simulates MultiMedia Key press events.

Thats a bit of a generalisation there. I have a laptop without multimedia keys. It is called a business laptop. My mother's consumer laptop, however, does have multimedia keys.

Not to be offensive... but really... NOT the point and NOT the answer to the question.

Likewise - Don't tell me what I have on my laptop, no offense of course.
I don't know if Enlish is your first language or not, but the phrase "just like all of us" tacked onto the end of a statement implies (or I've only ever heard it used to imply) that if the statement is not true for the listener/reader then he/she is somehow mentally deficient/wrong/retarded/idiotic/etc. I don't like being called that.

Yes... you not having multimedia controls on your laptop does make you deficient... of multimedia controls. You also are all the other words you mentioned, but not because of the absence of MM controls on your laptop but because you keep answering this post without really having anything REMOTELY RELATED to say about THE REAL QUESTION. So if you don't like being called "those things" stop acting accordingly.
P.S.: No, English is not my first language, but as you can see I speak it quite well. And please, I'm begging you, look up the phrase "just like all of us" in a dictionary!

You'll have to provide a link because I couldn't find it in a dictionary (on- or off- line). Idiomatic expressions often aren't in dictionaries unless you happen upon them through a specific word.

Note that I did mark my post as being "not an answer" so others can easily identify that it does not contain an answer.
I was mearly pointing out that in your original post you may reduce your chances of getting an answer because someone could have misinterpreted your opening statement as an implicit insult if the condition was false.

Oh... well, I guess that is why you have no idea that is has absolutely no offensive connotations. I was hoping that those who didn't actually have the respective keys could just ignore that part, you know, like *normal* people do.

Yes, I head African-Americans rolling in "da hood" swearing and insulting each other using those exact words. I even heard that someone actually got shot for using the phrase "just like all of us" when it wasn't 100% true.

I have multimedia keys on my laptop, and I know how to use them, manually and programmatically.
And if I would not know, I would know how to find out in a matter of seconds.
This being the weekend, I take a few days off, just like all of us.

Well then, have a nice weekend!
If I knew the answer and someone was asking for it, I would just paste a link or something, and I would feel much better about myself in the weekend cause I helped someone who needed it... just like most of us.

I know of no library to do what you want - I chuck keyboards away if they have all the MM and internet key and buy a business keyboard.
Create and app and detect the keydown event on a form to identify the keys and deal with them the way you need to. Doesn't every developer have a test app where snippets are tried
