This is a line in my code:
NSString *count = [[NSString alloc] initWithString: [sTemp substringFromIndex:[sTemp rangeOfString:@"count="].location + [sTemp rangeOfString:@"count="].length]];
One solution was
NSString *count = [[NSString alloc] //line 1
initWithString: [sTemp substringFromIndex:
[sTemp rangeOfString:@"count="].location +
[sTemp rangeOfString:@"count="].length]];
This is not the best sample, but the idea is:
1. Ok, the first line is the assignment and alloc thing.
2. The line 2 indent with a fell more right space. But, if the name of variable or type is very big, I will have the situation above. What I do?
NSStringWithVeryBigType *bigNameVariable = [NSStringWithVeryBigType alloc]
initWithString: [sTemp substringFromIndex:
3. IN second line I create a new NSString. I can be confuse if the line 3 and 4 (in a bad situation, not this) is the main function creation, or is this new one. Have a good rule about it? And if it have a big name too, what to do again...

The rename in the branch works as expected. When I switch back to the master branch the directory has its original name, but there's also an empty directory tree with the name that I changed it to in the branch.
Is this the expected behavior?
Am I missing a step?
Do I just need to delete these empty directory trees as they appear?
I know Git doesn't track empty directories and that may be a factor here.
My current workflow is:
# create and checkout a branch from master
/projects/demo (master)
$ git checkout -b rename_dir
# update paths in any affected files
# perform the rename
/projects/demo (rename_dir)
$ git mv old_dir new_dir
# add the modified files
/projects/demo (rename_dir)
$ git add -u
# commit the changes
/projects/demo (rename_dir)
$ git commit -m 'Rename old_dir to new_dir'
I get to this point and everything is as expected:
# old_dir has been renamed new_dir
/projects/demo (rename_dir)
$ ls
new_dir
The issue comes when I switch back to master:
/projects/demo (rename_dir)
$ git checkout master
# master contains old_dir as expected but it also
# includes the empty directory tree for new_dir
/projects/demo (master)
$ ls
old_dir new_dir
new_dir is an empty directory tree, so git won't track it - but it's ugly to have there.

my college assignment is to make an database,
such that
the database is able to generate a user interface which provides the best help to the TIME TABLE MAKER PERSON of the college
it manages all the issues relating to timetabling and extra issues request by the college.
my professor explained me that,
1) currently all the timetabling work is done on paper through mutual coordination.
i have to make a database for it whose 'schema' must be common to all departments.
2) now have to implement it in an distributed environment. Each department will/must be maintain/having its own computer where its data will be stored.
MY Answer 1) i have designed the database schema such that its one for all "can handle timetabling for all departments."
MY Answer 2)
for implementing this, i have to assume that
2a) each department will want to maintain its own database server. The software used will be "SQL SERVER 2005 EXPRESS".
2b)The website will connect to the needed data base server depending on the request of the client.
2c) one computer running IIS 5.0 windows XP to host the website.
2d) Assume there are 4 departments, i will need four computers running sql server 2005 express.
***The Question***
what term to use here "the database is distributed
or
the database is replicated"??
{
there is no distribute database feature in sql server 2005 express edition
}
"i do not think it will be distributed as the same schema will be running, on all computers"
that leaves replication,
if i use the "Replication feature" which is shown in micrsoft SQL Server Management Studio Express. The schema of the database will be replicated.
Now to access these db server i will still have to use different connection strings in C# coding, as the dbs reside on different computers, so whats the big deal?? its just copying paste-ing the db file to all that need it!!
am i right? i hope i am not,?
please guide.
Thank you.

2. Use a DTO, retrieve the existing entity using session.Load(dto.Id), assign new vaues from the dto, then save.
No1 requires much less effort, but sometimes I'm getting an exception: "a different object with the same identifier value was already associated with the session". Is there a simple way around that?

I am writing a program and so far I've stuck to the no more than 79 characters in a line rule. However I'm not sure where to break lines in a few situations.
Here are the problem areas:
self.proc.stdin.write('(SayText "%s")\n' % text.replace('\\', '\\\\').replace('"', '\\"'))
For this situation when I break first line after the '(SayText "%s")\n', the second line ends up being 80 characters long. Should I then break the second line somewhere in the brackets like this?
self.proc.stdin.write('(SayText "%s")\n'
% text.replace('\\',
'\\\\').replace('"', '\\"'))
Or would it be better to bring the entire third line to the beginning of the first brackets like this:
self.proc.stdin.write('(SayText "%s")\n'
% text.replace('\\',
'\\\\').replace('"', '\\"'))
Another example of this is here:
filename = tkFileDialog.askopenfilename(filetypes = (("Word list", "*.tldr"), ("All files", "*.*")))
Should I do this?
filename = tkFileDialog.askopenfilename(filetypes = (("Word list",
"*.tldr"),
("All files",
"*.*")))
Or this?
filename = tkFileDialog.askopenfilename(filetypes = (("Word list",
"*.tldr"),("All files", "*.*")))
What would be a good convention to follow?

% text.replace('\\',
'\\\\').replace('"', '\\"'))
Or would it be better to bring the entire third line to the beginning of the first brackets like this:
self.proc.stdin.write('(SayText "%s")\n'
% text.replace('\\',
'\\\\').replace('"', '\\"'))
Another example of this is here:
filename = tkFileDialog.askopenfilename(filetypes = (("Word list", "*.tldr"), ("All files", "*.*")))
Should I do this?
filename = tkFileDialog.askopenfilename(filetypes = (("Word list",
"*.tldr"),
("All files",
"*.*")))
Or this?
filename = tkFileDialog.askopenfilename(filetypes = (("Word list",
"*.tldr"),("All files", "*.*")))
What would be a good convention to follow?
Thanks. | 4 |

public new bool IsVisible
{
get { return base.IsVisible; }
set
{
base.IsVisible = value;
this.RaisePropertyChanged ( "IsVisible" );
}
}
So this property is set to `true` when left mouse button is down for the selected item in the`TreeView`. It works fine, but I also have a `CheckBox` I am trying to bind to the same property, two way. So whenever I change this property via left mouse button down, the `CheckBox` shows the IsVisible state if it's true. So this works partially.
But the problem is, each time when I set this property to true for an instance, all other layers' `IsVisible` property is set to false, but the `CheckBox`es don't show the changes. They still look checked.
So whenever I say:
layer.IsVisible = true;
all the other layers are set to false by the base class which I don't have access to the source code (shown above).

So i created work around. i created Winfrom that run on PC client and connect to my ASP.NET via WCF.
until now works fine, but the process become anoying for the client. because he has to work on ASP.NET to save the item and run the Winform and clic it to retrive the item from ASP.NET and print it.
nowdays i use PULL methode, that's meant that my Winform PULL the data from ASP.NET
i wonder if i can use PUSH methode, that meant the ASP.NET push the data to Winform and the client only clic one button on ASP.NET.
or how can i make my winform always listen into ASP.NET.
by the way, i want to simplify the client side, so he only clic one button instead of two.

Could someone explain the purposes of these two things, in 2d orthographical game, so that I can understand it better?
It feels like OpenGL is doing a lot of useless stuff in a 2d setup. Rasterizing and calculating fragments when the images are already there, converting vertex coordinates to NDC only to be converted back to what they already where by glViewport.

Right now, Simpletest, the Drupal testing framework works by installing and setting up the tables for every module needed for a test, which makes for slow tests, and I'm emulating a similar approach by loading a db dump for each test.
Given that a site, if you're doing integration testing has a 'known good' state to be starting from, I think it would be faster to be able to just revert back to that point each time, instead of waiting twenty seconds or so to drop the database then pipe the dumpfile back in between each test runs.
However, when I try diffing between two dumpfiles (ie `before.I.create.a.node.sql`, and `after.I.create.a.node.sql`) the output is an unreadable load of serialised php, that I can't make sense of.
Ae there any tools I can use to help work out which tables I need to drop and rebuild between test cases, so I don't incur the 20 second hit on each test, short of reading the schema and code of every module I'm working with?

I have a .Net WCF service (not a web service) with many methods, some accepting and returning complex data types. I use these services from my Windows Phone
7 apps. It all works great and it's easy.
Now I'm evaluating the feasibility of porting some of my apps to android but I can't figure out how to invoke my WCF services from an android client.
I have a working example I found at...
huup://naveenbalani.com/index.php/2011/01/invoke-webservices-from-android/
(code pasted below)
But this looks to be accessing a "Web Service" not a WCF Service.
My service is at huup://www.deanblakely.com/Service2.svc and it contains a simple method named "SimpleTest" that just returns the string "Alive".
Using the code below I put huup://www.deanblakely.com/Service2.svc in SOAP_ADDRESS and SimpleTest in OPERATION_NAME. But I have no idea what to put in
SOAP_ACTION and WSDL_TARGET_NAMESPACE. I don't even know if this approach is valid.
In .Net, Visual Studio builds us a "Service Reference" and everything just works.
I also don't understand the following two lines of code...
huupTransport.call(SOAP_ACTION, envelope);
Object response = envelope.getResponse();
With WCF services the call is async so we make the call to SimpleTestAsync and leave a callback for the async return. These two lines of code appear to be
synchronous, no?
Hope someone can help.

As the lead, I’m trying to balance best practices with an incredibly tight time line.
Here are the reasons I do NOT think Canonical is a good approach for our project.
- We have no immediate (<5 years) requirement to expose any internal services to the enterprise.
- Time required for governance. (Developing adapters with data transformation logic, developing XSDs, and developing contracts [fault, data, and operation]).
- No need to expose a different data contracts than what exists in the data layer
- It doesn’t appear that we can easily use ‘self tracking entities’ with the Canonical approach.
Here are some reasons I’m considering using Canonical approach.
- We can use the XSD schemas for data type and length validation.
- We will be prepared to allow consumption of our services to the enterprise, whether it’s 5 years or 1 year.
- We can feel good that we’re implementing best practices. :)
So, is it advisable to follow the Canonical approach with a Silverlight application? It does not seem that the benefits Canonical provide out weigh the additional work. …or perhaps I’m wrong and it’s not additional work.

(Which it was.) But I think it's a genuine question that needs to be discussed, so here's a much shorter version:
Abstractions are supposed to simplify your code. But in my experience maintaining other people's code, I consistently find that the trade-off for making code easier to write is making it harder to read, understand, and debug, especially if it's someone else doing the reading and debugging. In a lot of cases, it doesn't really reduce complexity; it just hides it or makes it someone else's problem.

my problem is when the entire form is sent to through the post request how do I know exactly which items were purchased?

would be the equivalent to the example at the top. but what if someone bought

- Setting up a WiX project (layout, references, file patterns)
- Integrating WiX into their solutions, build and release process
- Configuring installers (both for new installations and for upgrades)
I'd also be interested in any tricks or good hacks that you would like to share.
To get the ball rolling, here are a few things that we do:
1. Keep all variables in a separate include file e.g. Config.wxi
2. Define Platform variables for x86 and x64 builds
<!-- Product name as you want it to appear in Add/Remove Programs-->
<?if $(var.Platform) = x64 ?>
<?define ProductName = "Product Name (64 bit)" ?>
<?define Win64 = "yes" ?>
<?define PlatformProgramFilesFolder = "ProgramFiles64Folder" ?>
<?else ?>
<?define ProductName = "Product Name" ?>
<?define Win64 = "no" ?>
<?define PlatformProgramFilesFolder = "ProgramFilesFolder" ?>
<?endif ?>
An example using 1. and 2.
<Package InstallerVersion="200"
InstallPrivileges="elevated"
InstallScope="perMachine"
Platform="$(var.Platform)"
Compressed="yes"
Description="$(var.ProductName)" />
3. For our products, the simplest approach seems to be to always do major upgrades, so our ProductCode is set as * (auto-generate for each build) and our UpgradeCode is fixed to a unique Guid and will never change (unless we don't want to upgrade existing product)
4. Create an icon in Add/Remove Programs
<Icon Id="Company.ico" SourceFile="..\Tools\Company\Lib\Company.ico" />
<Property Id="ARPPRODUCTICON" Value="Company.ico" />
<Property Id="ARPHELPLINK" Value="http://www.example.com/" />
5. On release builds (we version our installers) copy msi to a deploy folder
<Target Name="CopyToDeploy" Condition="'$(Configuration)' == 'Release'">
<!-- Note we append AssemblyFileVersion, changing MSI file name only works with Major Upgrades -->
<Copy SourceFiles="$(OutputPath)$(OutputName).msi"
DestinationFiles="..\Deploy\Setup\$(OutputName) $(AssemblyFileVersion)_$(Platform).msi" />
</Target>

I've been using my Arduino mainly to test LED's and other small components, so I've kept it plugged into my laptop without any issues until now. Recently, I built a project using a receipt printer ([Hello Printer][1]), so it was necessary to plug the Arduino (connected to an ethernet shield and the printer) into a wall socket. Almost immediately, both boards began to heat up to the point where it hurt to touch. I unplugged it as quickly as I could, and there didn't appear to be any damage. My first thought was that I was using the wrong adapter, so I checked and confirmed that it is a 9v AC-DC adapter. My next thought was that the printer was using too much power, so I unplugged it and tested a simple LED blink program. That made the Arduino and the ethernet shield heat up as well. Finally, I tried the LED blink program in a different socket, only to have the same results. I am aware that it's normal for the board to heat up slightly, but this seems a little extreme.
What should I do? I'm all out of things to try.
Thanks in advance!

So, say the source directory has sub directories sub1, sub2, and sub3 in it and the target directory has sub1, sub2, sub3, and sub4 in it then I'd like to delete sub1, sub2, and sub3 from target dir.
I thought I could do this by using a FileSelector to identify all directories in source that are present in target. However, I can't get the <type> file selector to ever return a match for directories.
Ultimately, I figured I'd do something like:
<fileset id="dirSelector" dir="${install.dir}">
<type type="dir"/>
<present targetdir="${dist.dir}"/>
</fileset>
I started by just trying to list the directories present in the source directory and print them out:
<fileset id="dirSelector" dir="${install.dir}">
<type type="dir"/>
</fileset>
<property name="selected" refid="dirSelector" />
<echo>Selected: ${selected}</echo>
However, I never get anything printed with the type selector set to directory. If I change the type to file I do get files printed out.
Is there a better way to accomplish what I'm trying to do? Am I missing something in my use of the type selector? | ant | fileset | null | null | null | null | open | How do I select subdirectories in ant using a FileSet?

I'm using ant 1.6.2 and am trying to set up a task that will compare a source and a target directory, identify all the subdirectories that exist in the source directory and delete liked named subdirectories in the target directory.
So, say the source directory has sub directories sub1, sub2, and sub3 in it and the target directory has sub1, sub2, sub3, and sub4 in it then I'd like to delete sub1, sub2, and sub3 from target dir.
I thought I could do this by using a FileSelector to identify all directories in source that are present in target. However, I can't get the <type> file selector to ever return a match for directories.
Ultimately, I figured I'd do something like:
<fileset id="dirSelector" dir="${install.dir}">
<type type="dir"/>
<present targetdir="${dist.dir}"/>
</fileset>

I came across the above quote the other day. I get that many features unique to java (over c++) like garbage collection were initially found in Lisp. But how else did java drag c++ programmers **half way** to lisp? | java | lisp | null | null | null | 09/14/2010 18:13:07 | not constructive | how is java inspired by lisp?

<pre>
git reset --hard HEAD
git clean -f -d

This works for the most part. However there is a directory /shared/media that we <b>don't</b> want to be touched, even though there is a "media" symlink checked into git.
I've added "media" to .git/info/exclude, but regardless, "git reset --hard HEAD" removes /shared/media and replaces it with the checked in symlink.
Is there any way to get "git reset --hard HEAD" to leave this directory alone, other than e.g. by moving it out of the way beforehand and restoring it afterwards?
