Awesome: how to toggle marking of a client?

I'm fairly new to Awesome, so forgive me if I am missing something obvious.
I simply want to set Win+t to toggle the marking of a client, and if it's marked to put a red border round the client window.
He's what I've put in my theme.lua:
theme.border_marked = "#ff0000"
and in rc.lua:
clientkeys = awful.util.table.join(
awful.key({ modkey, }, "f", function (c) c.fullscreen = not c.fullscreen end),
awful.key({ modkey, "Shift" }, "c", function (c) c:kill() end),
awful.key({ modkey, "Control" }, "space", awful.client.floating.toggle ),
awful.key({ modkey, }, "t", awful.client.togglemarked ),
Despite 'man awesome' saying "Mod4 + t [to] Mark a client" no code to execute this exists in the default Awesome rc.lua file, hence my addition as above. However, when I restart Awesome. my client doesn't seem to get marked (and shows no red border) when I press Win+t.
Any help to resolve this would be most welcome.

Despite 'man awesome' saying "Mod4 + t [to] Mark a client" no code to execute this exists in the default Awesome rc.lua file.
This was a bug, I fixed it recently, but Mod4+t now sets the client on-Top: http://git.naquadah.org/?p=awesome.git; … h=fda2c091
However, when I restart Awesome. my client doesn't seem to get marked (and shows no red border) when I press Win+t.
Your client does get marked, only the visual cue is missing. When you press Mod4+t and mark the client, a "marked" signal is emitted now you need to attach a handler to the signal that will change the clients border color to beautiful.border_marked (same goes for unmarked to revert the border color).
Marking was removed a few months ago from default rc.lua, even though the functionality is still in awful it is probably deprecated, and to be removed.

I have a similar chat application. When the user attempts to connect, instead of sending a simple string, the client sends a serialized object(xml string) with all relevant login and session information, this includes the user's IP address. Once the server
receives said information, depending on the type of TCP broadcast (a custom enumerated type) information from one user may be passed to a single user, or distributed to many users.
If it helps, here is the TCPBroadcast object I use. But in order for your server to understand it, you kind of have to build your server and client somewhat around it.

How can I mark an email as SPAM without "opening" it?

When I go to "the cloud" to read my email, I might see spam there.
But when I click on the email message to mark it as spam or even
delete it, I've "opened" the email. I don't want to do that, right!!!
So how can I mark it as spam *or* delete it without "opening" the
email in question.
Thanks!
[and oh, by the way, since moving to the cloud, I've gotten lots of
spam -- something I almost never got with me.com. just fyi...]

You need to have the account set up as IMAP or Exchange (iCloud, Gmail, Yahoo, etc. automatically do this if you choose that option when you create the account). POP3 accounts do not supporting synchronizing between clients and the server.

How can I mark event as "done" so that I see this at one glance?

how can I mark an event on ical as "done" so that I see this at one glance? In outlook this was possible, there was a white line on the left once I had marked the event as "done".

Greetings,
If you are new iCal user read this: http://support.apple.com/kb/HT2513
Events are more along the lines of a...well...event "Appointment with Dr. Smith"..."Travel to Mexico"..."Jon's Birthday".
What you are describing is what I would call a task. iCal offers "To Dos" for that purpose which include a check box for completion.
Cheers!

Async tcp client and server. How can I determine that the client or the server is no longer available?

Hi,
Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

How do I mark a "not measurable" event on a chart history?

I have an application which is working very well and takes measurements - continuously plotting a result on a chart. The chart history is typically a 100 or so measurements. I plot on the chart both an upper and lower tolerance limit, hence the measurment plot should hopefully stay between the two (straight lines) limits.
Occasionally a sample is "missing" and when this happens a "measurement" of zero is given. This is currently displayed on the chart as a sudden drop to zero. The users like this as it shows them clearly that the sample was missing. All OK so far, however...
On rare occasions a sample is present and is measured but for reasons I will not go into we know (and the software can determine) that the measurement result is actually invalid. This situation I call "not measurable" in that although a sample is present it actually cannot be properly measured. The question is this; how do I show this on my chart history?The chart history plot is by far the most looked at display of data for the users. I realise that I could show a message box saying "not measurable" (and intend to do so) but this would only last for that measurement cycle. How do I "mark" the chart to show that there was a sample but that it was not measurable.
I don't particularly want to use a zero value because that is being used quite nicely for the "no sample" situation. Also I don't want to simply not plot anything because the fact that the sample was "not measurable" is potentially very important indeed. Ideally what I would like is to put a marker, say a thick vertical line at the position where the invalid measurment is, in order to both block it out to show that it is wrong and also show there actually was a sample there in the first place.
Any ideas as to how I can do this? Sorry this is a bit wordy!
Regards
Kevin

Hi
I have come up with a quick fix for using a chart which might give you a few ideas. This is just a quick fix and isn’t very nice at all. The green dots are meant to represent the immeasurable data, I have just triggered them by a set of limits. You would be better of using an XY plot and an array which you constantly up date. Using an XY graph will give you a lot more options such as using cursors to mark certain points.
I have attached my quick fix and an example of using text on an XY graph
Hope this at least gives you some ideas

How can I allow a user (client) to choose a local image file (on his hard d

How can I allow a user (client) to choose a local image file (on his hard drive) and modify it using an applet from his browser ? I am trying to develop a web page that enables the user to choose an Image file, manipulate the image using a java applet, and display the results.
Using Java�s �JFileChooser� does not work when called from a browser, probably due to security privileges issues. On the other hand, I can choose and upload any file using a JavaScript form:
<FORM METHOD="POST" ENCTYPE="multipart/form-data" ACTION="process.asp">
<INPUT TYPE=FILE NAME="file1"><BR>
�
It seems that I can choose an image file with a Java script form and process an image with an applet. How can I choose a file AND process it locally ?
(I do not wish to upload the file to the server using JavaScript form and then back to the client�s applet for processing since it will be a tremendous waste of resources).
Will appreciate any solution.
Thanks !
( my email is: [email protected] )

"Using Java�s �JFileChooser� does not work when called from a browser, probably due to security privileges issues. "
You can do this if you sign the applet...

How can I mark something as 'helpful' or 'the correct answer' ?

I have been posting a handful of questions within the DreamweaverCC forum.
I notice that there indications that 5 people have marked the replies as 'helpful'.
How can I mark some of the responses to my posts as helpful ?
I am unable to do this.
Under my 'Actions' button it says "no actions available".
I also do not have the ability to edit my own posts.
For instance, I have resolved one of the problems and I would like to clean up my own post eliminating the 'noise' and leaving the relevant.
This is for the sake of others. I have noticed that one of my posts has 200+ views. I do not want to waste people's time.
During the first week of may, the Adobe FORUMS had a message for a couple of days that they were doing a major overhaul of the Forum.
Since then I am unable to sign in to the forums (or to Adobe.com) from my ipad.
I upgraded my IOS, and cleared cookies and history.
note. Today I was doing a general search on my ipad (w/o) logging in.
I wanted to see what was out there about header.php.
I came across my own post (which requires cleanup).
I came across another person's. It made me laugh.
The individuals who were helping him asked him to post his code
which ultimately ended up in the longest scroll in the world (hundreds of div ids).
The responders said 'nightmare'.
It made me laugh because I am certain that part of my posts elicit the same response (nightmare)
I would like to clean them up.

Thanks Hans-Günter.
Yes, I have noticed that elsewhere. I just do not have those options.
Okay. After I clicked my own response to you - then the greenStar 'correct answer showed up.
So I clicked the 'greenstar' on your response.
Guess what ?
Earlier, I emailed Preran because there weren't any options under my 'Actions' button for instance 'edit or 'delete'.
They are now there !!

What is the best way to navigate to my own posts so that I can follow them ?
The only way I can do this is by clicking on my inbox & activity under my profile icon.
There is a list of the latest responses and emails but it is not really a list of my own posts.

machine. I already written a program which can be used at the time of zooming and panning
of the image and can throw the image but that is all PC based. but when I am implementing
on the server it is giving error because code is not getting any output directory to save
the image on sever.
Please tell me if that can be happen through caching or how can I save image on
client machine without user authenication and can retrieve on the web page. so that my
server doesn't have extra load.

HOW TO GET INFORMATION ABOUT THE CLIENT MACHINE AT DATABASE LEVEL

HOW TO GET INFORMATION ABOUT THE CLIENT MACHINE AT DATABASE LEVEL USING 10g Database and 10g Application Server
we have developed an application using oracle forms 10g with
oracle database 10g and Application server 10g
Application uses a single Oracle User name to connect to database
where as at Application level there are different users (these are not database users)
Now how can we get the information about the user/his machine etc. at database level. earlier in 6i/8i we use to get by using
USERENV('TERMINAL')
we had written a triggers on tables on Insert/Update where we used to update a database field Last user terminal with USERENV('TERMINAL')
but not this information is comming to be the machine name of application server where as we wish this to be the machine name of Client. Any Way outs
thanks

hi, you can use the sys_context function, like this:
select sys_context('userenv','current_user'),
     sys_context('userenv','os_user'),
     sys_context('userenv','host'),
     sys_context('userenv','ip_address'),
     sys_context('userenv','instance'),
     sys_context('userenv','sessionid'),
     sys_context('userenv','terminal')
from dual;
Is this what you 're looking for?

How do I bind 10.4 clients to a 10.5 server?

I've been given the task of cleaning up a Mac network that has 15 iMacs....some running 10.4 and some 10.5.
2 issues
1 - as a test I created an account called MacA on the server, and there are only 6 other accounts listed in the server....BUT, some of the iMacs that have complete access to the server, are not listed in the accounts on the server. So I can go to some of the 15 iMacs, and login as JohnD and have complete access, but JohnD is not on the list of server accounts. this seems to just be a roaming client in the network, how do I delete these roaming clients?
2 - When I am on a Machine that is running 10.5, I go to SYST PREF>ACCTS>LOGIN OPTIONS> and then a NETWORK ACCT SERVER(JOIN) option shows.....when I CLICK on this, I can type in the name of the central Mac server, and VOILA, I can then log in as the user MacA that I created on the central server
HOWEVER
on a machine running 10.4, when clicking on SYST PREF>ACCTS>LOGIN OPTIONS....there is no NETWORK ACCT SERVER(JOIN) option.....
what am I doing wrong.....and how exactly do I go about JUST creating accounts/users on the central server, and when these client machines get the login popup, ONLY the accounts that I've created can login to the server?

Hi
+"1- I create a user on the 10.5 server in accounts"+
From what you've been saying of what it is you think you want to do, this is not the place to be creating network accounts. Assuming I've understood what it is you want. Launch WorkGroup Manager. Select the LDAPv3 node. Create users you wish to have desired network homes. Assign passwords or define a Password Policy. In the Homes tab select the share point you've already shared and defined as an auto-mount for networked homes. Click Create Home Now. Click Save. That's basically it. Repeat the process for however many users you have or want. Alternatively create all the users you want first in one go. Select them all (apart from diradmin) and click Create Home now followed by Save.
All of this assumes:
(a) DNS is correctly configured
(b) Users are defined in the correct directory
(c) Server is correctly configured to allow LDAP accounts
(d) Workstations are using the relevant DNS Server
These are just to begin with.
+"b - allow network users to login to this computer (it is here that I see the users that I've created on the server, and put them on the list to allow to login)"+
IMO there truly is no need to do this at the stage you're at now. Get the basics figured out correctly. Above all just get it working. If it's a requirement for your environment to control and/or manage - later on - which network based accounts are allowed to login on designated workstations look at that option then.
NB: Local accounts will always take precedence over networked accounts if named exactly the same.

How do I mark the entire contents of a RichTextBox (gRTbxInfo) with a background color of white?

How do I mark the entire contents of a RichTextBox (gRTbxInfo) with a background color of white?
I have code that finds / marks words with a different color. Now I want to remove that color. I've started with the following, but cannot complete it.
    //int iLength = gRTbxInfo.Length
    int iLength = 10;
    TextRange trText = new TextRange(gRTbxInfo.Document.ContentStart, gRTbxInfo.Document.ContentEnd);
    TextPointer tpStart = trText.Start.GetInsertionPosition(LogicalDirection.Forward);
    TextPointer tpSelectionStart = tpStart.GetPositionAtOffset(0, LogicalDirection.Forward);
    TextPointer tpSelectionEnd = tpSelectionStart.GetPositionAtOffset(iLength, LogicalDirection.Forward);
    TextRange tpSelection = new TextRange(tpSelectionStart, tpSelectionEnd);
    tpSelection.ApplyPropertyValue(TextElement.BackgroundProperty, new SolidColorBrush(Colors.White));

Isn't that just
TextRange tr = new TextRange(rtb.Document.ContentStart, rtb.Document.ContentEnd);
tr.ApplyPropertyValue(TextElement.BackgroundProperty, Brushes.White);
Hope that helps.

How do I get list of client IP Addresses using new Airport Utility v6.3?

I have purchased and Airport Time Capsule 3TB (newest model). Previous models were still compatible with Airport Utility 5.6 and I could use "manual" mode to get a list of client IP addresses attached to the device. The new Airport Time Capsule is only compatible with Airport Utility 6.3 and I cannot figure out how to get a list of client IP addresses with this new model. Does anyone know how to do this?

Try a ping broadcast - for example if your network were 192.168.1.xxx (netmask of 255.255.255.0) try this from a Termnal.app window (located in /Applications/Utilities):
ping 192.168.1.255
If you have a different type netmask, you need to put 255's where the 0's are in your netmask.
Everyone on the local network (the 192.168.1.xxx network) should reply that is up and running unless you have them setup to not respond to pings (the WAN port on your TC should not reply cause it's in a different network) and you have your list of clients on the network. If you setup the TC to dedicate a range of addresses for WiFi clients you can even identify which of them are wired and which are wireless.
good luck.

In Mail: how do I mark prior emails as read.

Aside from opening them one at a time, how can I mark prior emails as "read" in one or two steps?
Thanks!

Select all (command A) in the mailbox.
