• error reporting issues

  - by SunnyOne

  I'm still entangled in error handling problems. After having read and tried lots of different scripts, I still do not have an overall insight on the problem. I made a syntax error on purpose and get the following error message : Parse error: syntax error, unexpected '{' in /home/directory/public_html/mypage.php on line 10 To understand how it work, as a first step, I'd like to remove this message(which I'am able to do) and replace it by a custom one. How can I customize this message ? Thanks a lot.

• Any way to find out which line break char(s) to use in Javascript?

  - by Irro

  I'm trying to parse some text into a textarea control and at the same time replace all with ordinary line break chars. I have been able to do it in windows by replacing with CR (it didn't work with CRLF strangely enough, it gave me linebreak + empty space) but I'm afraid that this code won't work in Unix/Mac because they use LF for line break. Is there any way to use the system default line break char in javascript? Something similar to Environment.NewLine in .Net (I wasn't able to write backslash in this editor but I use /r for CR and /n for LF, replace / with backslash)

• PHP troubleshooting unexpected T_PUBLIC error

• Translate This git_parse_function to zsh?

  - by yar

  I am using this function in Bash function parse_git_branch { git_status="$(git status 2> /dev/null)" pattern="^# On branch ([^${IFS}]*)" if [[ ! ${git_status}} =~ "working directory clean" ]]; then state="*" fi # add an else if or two here if you want to get more specific if [[ ${git_status} =~ ${pattern} ]]; then branch=${BASH_REMATCH[1]} echo "(${branch}${state})" fi } but I'm determined to use zsh. While I can use this perfectly as a shell script (even without a shebang) in my .zshrc the error is a parse error on this line if [[ ! ${git_status}}... What do I need to do to get it ready for zshell? Note: I realize the answer could be "go learn zsh syntax," but I was hoping for a quick hand with this if it's not too difficult.

• parsing command option with default values and range constrains in C

  - by agramfort

  Hi, I need to parse command line arguments in C. My arguments are basically int or float with default values and range constrains. I've started to implement something that look like this: option_float(float* out, int argc, char* argv, char* name, description, float default_val, int is_optional, float min_value, float max_value) which I call for example with: float* pct; option_float(pct, argc, argv, "pct", "My super percentage option", 50, 1, FALSE, 0, 100) however I don't want to reinvent the wheel ! My objective is to have error checking of range constrains, throw an error when the option is not optional and is not set. And generate the help message usually given by usage() function. The usage text would look like this: --pct My super percentage option (default : 50). Should be in [0, 100] I've started with getopt but it is too limited for what I want to do and I feel it still requires me to write too much code for a simple usecase like this. thanks

• Is it possible to add two nodes at a time dynamically to a treeview

  - by Dorababu

  I am having a tree-view on my main form with initially some nodes as follows ACH |-> some.txt |->FileHeader |->BatchHeader Now at this point i will have to add 2 child nodes at a time to BatchHeader. This nodes i will pass as strings from child forms My sample code that i added some nodes is as follows public void loadingDatafrom(string filename, bool str) { if (Append.oldbatchcontrol != filename) { if (tvwACH.SelectedNode.Text == "FileHeader") { tvwACH.SelectedNode.Nodes.Add(filename); } if (tvwACH.SelectedNode.Text == "BatchHeader" && filecontrolvariables.m_gridclick == false) { tvwACH.SelectedNode.Nodes.Add(filename); **I got this idea tvwach.SelectedNode.Lastnode.Nodes.Add("Node");** } } } Can any one give an idea to add 2 nodes as child to the existing node ..

• Pass value to an include file in php.

  - by Muhammad Sajid

  Hi, How do you pass a parameter into an include file? I tried the following but it doesn't work. include "myfile.php?var=123"; and in myfile.php, I try to retrieve the parameter using $_GET["var"]. include "myfile.php?var=123"; will not work. PHP searches for a file with this exact name and does not parse the parameter for that I also did this: include "http://MyGreatSite.com/myfile.php?var=123";but it does not also work. Any hints? Thanks.

• To use package properly, how to arrange directory, file name, unit test file?

  - by Stephen Hsu

  My source files tree is like this: /src /pkg /foo foo.go foo_test.go Inside foo.go: package foo func bar(n int) { ... } inside foo_test.go: package foo func testBar(t *testing.T) { bar(10) ... } My questions are: Does package name relates to directory name, source file name? If there is only one source file for a package, need I put it in a directory? Should I put foo.go and foo_test.go in the same package? In the foo_test.go, as it's in the same package as foo.go, I didn't import foo. But when I compile foo_test.go with 6g, it says bar() is undefined. What should I do?

• Actual SQL statement after bind variables specified

  - by bioffe

  I am trying to log every SQL statement executed from my scripts. However I contemplate one problem I can not overcome. Is there a way to compute actual SQL statement after bind variables were specified. In SQLite I had to compute the statement to be executed manually, using code below: def __sql_to_str__(self, value,args): for p in args: if type(p) is IntType or p is None: value = value.replace("?", str(p) ,1) else: value = value.replace("?",'\'' + p + '\'',1) return value It seems CX_Oracle has cursor.parse() facilities. But I can't figure out how to trick CX_Oracle to compute my query before its execution.

• Securing database keys for client-side processing

  - by danp

  I have a tree of information which is sent to the client in a JSON object. In that object, I don't want to have raw IDs which are coming from the database. I thought of making a hash of the id and a field in the object (title, for example) or a salt, but I'm worried that this might have a serious effect on processing overhead. SELECT * FROM `things` where md5(concat(id,'some salt')) = md5('1some salt'); Is there a standard practice for obscuring IDs in this kind of situation?

• WPF Datatemplate + ItemsControl each item uses > 1 MB Memory?

  - by Matt H.

  Does that sound right to anyone???? I have an ItemsControl that displays data from a custom object that implements iNotifyPropertyChanged. The DataTemplate consists of: Border 3 buttons 5 textboxes An ellipse A Bindable RichTextBox (custom class that inherits from RichTextBox... so I could make Document a dependency property (to support binding)) Several grids and stackpanels for layout It uses: Styles (stored in a resource dictionary higher up the tree) Styles affect: colors, thicknesses, and text properties: which are data-bound to a "settings" class that implements iNotifyPropertyChanged, so the user can change display settings That's it! So what gives? I've also noticed that when I empty and remove the ItemsControl, memory isn't freed. over 5000 instances of "CommandBindingCollection" and "WeakReference" are CREATED (using ANTS profiler). And huge number of EffectiveValueEntry objects are created too. So really, what gives!!! :-) Thanks for your insight! Management needs this project soon but in its current state, it's unreleasable.

• How to access a subset of XML data in Java when the XML data is too large to fit in memory?

  - by Michael Jones

  What I would really like is a streaming API that works sort of like StAX, and sort of like DOM/JDom. It would be streaming in the sense that it would be very lazy and not read things in until needed. It would also be streaming in the sense that it would read everything forwards (but not backwards). Here's what code that used such an API would look like. URL url = ... XMLStream xml = XXXFactory(url.inputStream()) ; // process each <book> element in this document. // the <book> element may have subnodes. // You get a DOM/JDOM like tree rooted at the next <book>. while (xml.hasContent()) { XMLElement book = xml.getNextElement("book"); processBook(book); } Does anything like this exist?

The action triggers a java function. How do i see which checkboxes are checked?

Appreciate all the help in advance. Thanks

• Is there a way to use XDocument in the Application Settings?

  - by Shimmy

  I have to store a complex type in the application settings. I thought that storing it as XML would work best. The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value. Is there a way to use XDocument or XML in application settings?

• Getting unevaluated tcl arguments

  - by user1327792

  What I want to do is parse an argument to a tcl proc as a string without any evaluation. For example if I had a trivial proc that just prints out it's arguments: proc test { args } { puts "the args are $args" } What I'd like to do is call it with: test [list [expr 1+1] [expr 2+2]] And NOT have tcl evaluate the [list [expr 1+1] [expr 2+2]]. Or even if it evaluated it I'd still like to have the original command line. Thus with the trivial "test" proc above I'd like to be able to return: the args are [list [expr 1+1] [expr 2+2]] Is this possible in tcl 8.4 ? Thank you. -MP

• Figuring out Host's Top Domain with Javascript

  - by timeitquery

  Is there a way to figure out what the top domain for the hostname of the current page is? The problem I have is that the script could be on .com domain, or in an international domain like .co.uk So for: jobs.telegraph.co.uk - top domain is:telegraph.co.uk jobs.nytimes.com - top domain is nytimes.com The problem is that location.hostname , and the document.domain give the entire domain. One route is to have a list of all TLDs (too much to carry around) and parse based on that. Another route was if 2 characters after last ".", than internationaltion - hence last two are the TLD, but that does not hold true for all international domains.

• Determine if e-mail message can be successfully sent

  - by Felipe Lima

  Hello Everyone, I am working in a mailing application in C# and, basically, I need to be able to determine which recipients successfully received the message, which ones did not, no matter what was the failure reason. In summary, I need an exception to be thrown whenever the email address does not exist, for example. However, SmtpClient.Send does not throw an exception in this case, so I'd need to monitor the delivery failure replies and parse them, maybe. I know this is not a simple task, so I'd ask you experts some tips on how to handle the main issues with email sending. Thanks in advance!!

• Simple, Custom Parsing with c++

  - by bradkovach

  Hi! I have been reading SO for some time now, but I truly cannot find any help for my problem. I have a c++ assignment to create an IAS simulator. Here is some sample code... 0 1 a 1 2 b 2 c 3 1 10 begin 11 . load a, subtract b and offset by -1 for jump+ 11 load M(0) 12 sub M(1) 13 sub M(3) 14 halt Using c++, I need to be able to read these lines and store them in a "memory register" class that I already have constructed... For example, the first line would need to store "1 a" in register zero. How can I parse out the number at the line beginning and then store the rest as a string? I have setup storage using a class that is called using mem.set(int, string);. int is the memory location at the beginning of the line and string is the stored instruction.

• How can I pass a type as a parameter in scala?

  - by rsan

  I'm having a really hard time trying to figure out how can I store or pass a type in scala. What I want to achive is something like this: abstract class Foo( val theType : type ) object Foo{ case object Foo1 extends Foo(String) case object Foo2 extends Foo(Long) } So at some point I can do this: theFoo match{ case String => "Is a string" case Long => "Is a long" } and when obtaining the object being able to cast it: theFoo.asInstanceOf[Foo1.theType] Is this possible? If is possible, is a good aproach? What I'm trying to achieve ultimately is writing a pseudo schema for byte stream treatment. E.g if I have an schema Array(Foo1,Foo1,Foo2,Foo3,Foo1) I could parse Arrays of bytes that complain with that schema, if at some point I have a different stream of bytes I could just write a new schema Array(Foo3, Foo4, Foo5) without having to reimplement parsing logic. Regards,
