  • Screen Scraping HTML with C#

    - by WildBill
    I have been given the task at work of screen scraping one of our legacy web apps to extract certain data from the code. The data is formatted and "should" be displayed exactly the same every time. I am just not sure how to go about doing this. It's a full html file with header and footer navigations but in the middle of all this is the data I need. I need to extract the Company Name value, Contact Name, Telephone, email address, etc. Here is an example of what the code looks like: ...html above here <br /><br /> <table cellpadding="0" cellspacing="12" border="0"> <tr> <td valign="top" align="center"> <!-- Company Info --> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="black"> <table cellspacing="1" cellpadding="0" border="0" width="370"> <tr> <th>ABC INDUSTRIES</th> </tr> <tr> <td class="search"> <table cellpadding="5" cellspacing="0" border="0" width="100%"> <tr> <td> <table cellpadding="1" cellspacing="0" border="0" width="100%"> <tr> <td align="center" colspan="2"><hr></td> </tr> <tr> <td align="right" nowrap><b><font color="FF0000">Contact Person&nbsp;<img src="/images/icon_contact.gif" align="absmiddle">&nbsp;:</font></b></td> <td align="left" width="100%">&nbsp;Joe Smith</td> </tr> <tr> <td align="right" nowrap><b><font color="FF0000">Phone Number&nbsp;<img src="/images/icon_phone.gif" align="absmiddle">&nbsp;:</font></b></td> <td align="left" width="100%">&nbsp;555-555-5555</td> </tr> <tr> <td align="right" nowrap><b><font color="FF0000">E-mail Address&nbsp;<img src="/images/icon_email.gif" align="absmiddle">&nbsp;:</font></b></td> <td align="left" width="100%">&nbsp;<a HREF="mailto:[email protected]">[email protected]</a></td> </tr> more...

  • No Commons Logging in Android?

    - by Joe Boese
    Hello all, I have a pretty big library I developed specifically for use in my Android Application. However business logic itself has no dependency on Android. To preserve that, I used Commons Logging throughout this library and it's respective JUnit tests (which I run in Eclipse). However now that I am starting to integrate it into an Activity which I launch on Android, I am unable to get my logging to work. In Eclipse/JUnit, I had simply pulled in log4j's jar file as well as a log4j.properties file. This doesn't seem to work when deploying to a device. After struggling with attempting to get that to work for several hours, I gave up and tried replacing all my commons logging stuff with android.util.Log. Now I can log on the device.. but all JUnit tests are broken. When any JUnit tries to log using android.util.Log, it throws a RuntimeException 'Stub!'. I would prefer to revert to my commons logging approach.. if anyone can help with that.. otherwise.. what can I do to get my JUnit test cases running using 'android.util.Log'? Many thanks in advance.. I've spent more than a few hours on this and I'd like to move on to writing real code again! Joe

  • c - strncpy issue

    - by Joe
    Hi there, I am getting segmentation fault when using strncpy and (pointer-to-struct)-(member) notation: I have simplified my code. I initialise a struct and set all of it's tokens to an empty string. Then a declare a pointer to a struct and assign the address of the struct to it. I pass the pointer to a function. I can print out the contents of the struct at the beginning of the function, but if I try to use the tp - mnemonic in a strncpy function, I get seg fault. Can anyone tell me what I am doing wrong? typedef struct tok { char* label; char* mnem; char* operand; }Tokens; Tokens* tokenise(Tokens* tp, char* line) { // This prints fine printf("Print this - %s\n", tp -> mnem); // This function gives me segmentation fault strncpy(tp -> mnem, line, 4); return tp; } int main() { char* line = "This is a line"; Tokens tokens; tokens.label = ""; tokens.mnem = "load"; tokens.operand = ""; Tokens* tp = &tokens; tp = tokenise(tp, line); return 0; } I have used printf statements to confirm that the code definitely stops executing at the strncpy function. Can anyone tell me where I am going wrong? Many thanks Joe

  • Non-Mainstream Languages, Bad for your resume?

    - by Joe
    Hi folks, I got my BS in Computer Science about seven years ago. I spent two years in neuroscience research and the next three providing what amounts to tech support. But I love computer programming - and I have since written, as a freelancer, non-trivial commercial code in Haskell, Smalltalk, and Objective-C. I used these languages because I find them rewarding, they make me a better programmer and thus, I thought, more attractive to companies. However the polar opposite has occured and I am now unhireable. The freelance market has bottomed out and I am looking for regular employment. But I am being repeatedly turned down, even for entry-level positions, because I don't specifically fit the requirements - eg. Java programmer with 2+ years with JUnit, JavaMail, Servlets etc. And none of the hiring managers, let alone the recruiters, have heard of either Haskell or Smalltalk and more disturbing is their thinly veiled contempt for my background. My question is , how should I market myself to these positions? Is anyone here in a similar position? What should I be doing different professionally? More broadly is this contempt for non-mainstream experience occurring everywhere or just my town? And if there are any hiring managers reading this, I'd love to hear your side. Please be brutally honest. thanks, joe

  • Python Django Global Variables

    - by Joe J
    Hi all, I'm looking for simple but recommended way in Django to store a variable in memory only. When Apache restarts or the Django development server restarts, the variable is reset back to 0. More specifically, I want to count how many times a particular action takes place on each model instance (database record), but for performance reasons, I don't want to store these counts in the database. I don't care if the counts disappear after a server restart. But as long as the server is up, I want these counts to be consistent between the Django shell and the web interface, and I want to be able to return how many times the action has taken place on each model instance. I don't want the variables to be associated with a user or session because I might want to return these counts without being logged in (and I want the counts to be consistent no matter what user is logged in). Am I describing a global variable? If so, how do I use one in Django? I've noticed the files like the urls.py, settings.py and models.py seems to be parsed only once per server startup (by contrast to the views.py which seems to be parsed eache time a request is made). Does this mean I should declare my variables in one of those files? Or should I store it in a model attribute somehow (as long as it sticks around for as long as the server is running)? This is probably an easy question, but I'm just not sure how it's done in Django. Any comments or advice is much appreciated. Thanks, Joe

  • VBA Macro to save an excel file to a different backup location

    - by Joe Taylor
    I am trying to create a Macro that either runs on close or on save to backup the file to a different location. At the moment the Macro I have used is: Private Sub Workbook_BeforeClose(Cancel As Boolean) 'Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean) 'Saves the current file to a backup folder and the default folder 'Note that any backup is overwritten Application.DisplayAlerts = False ActiveWorkbook.SaveCopyAs Filename:="T:\TEC_SERV\Backup file folder - DO NOT DELETE\" & _ ActiveWorkbook.Name ActiveWorkbook.Save Application.DisplayAlerts = True End Sub This creates a backup of the file ok the first time, however if this is tried again I get: Run-Time Error '1004'; Microsoft Office Excel cannot access the file 'T:\TEC_SERV\Backup file folder - DO NOT DELETE\Test Macro Sheet.xlsm. There are several possible reasons: The file name or path does not exist The file is being used by another program The workbook you are trying to save has the same name as a... I know the path is correct, I also know that the file is not open anywhere else. The workbook has the same name as the one I'm trying to save over but it should just overwrite. Any help would be much appreciated. Joe

  • firefox and javascript redirection

    - by Joe
    Hello there, I currently have a issue with firefox, where all other browser behave in the right way - even IE6! What I want to do is redirection to a subpage but leaving a history entry. There are 2 methods of rewriting the url as far as I know: window.location = "some.url"; - redirect to some.url with history entry window.location.replace("some.url"); - redirect without history entry So I have to use the first one and tested in the firebug console everthing works fine. Now there is the kind of strange part of this question: the same statement, that worked fine in the console doesn't in some jQuery callback handler: jQuery("#selector").bind("submit", function() { $.getJSON("some_cool_json", function(response) { var redirect_path = response.path; window.location = redirect_path; }); return false; }); where response_path is set correctly, I checked it! Even the redirection is working correctly, but there is no history entry created. Any ideas on that one? Would be great! ;) Cheers Joe

  • Question about passing data using intents

    - by Joe K 1973
    Hi everyone, I'm trying to modify the Notepad tutorial (the Notepadv3 solution) to take in a value into the NoteEdit class, given to by the Notepadv3 class. I've successfully used .putExtra in the OnListItemClick method to place the value into the NoteEdit class, but I'm struggling to do this for the createNote method; I'm getting a force close when I try to create a new note. I bet there's a simple solution, but I'm pretty new to Java & Android and would very much appreciate your help. Here's the code in question in the Notepadv3 class: private void createNote() { Intent i = new Intent(this, NoteEdit.class); i.putExtra("key", 1); startActivityForResult(i, ACTIVITY_CREATE); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); Intent i = new Intent(this, NoteEdit.class); i.putExtra(NotesDbAdapter.KEY_ROWID, id); i.putExtra("key", 1); startActivityForResult(i, ACTIVITY_EDIT); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent intent) { super.onActivityResult(requestCode, resultCode, intent); fillData(); } And here's the receiving code in the NoteEdit class: mRowId = savedInstanceState != null ? savedInstanceState.getLong(NotesDbAdapter.KEY_ROWID) : null; if (mRowId == null) { Bundle extras = getIntent().getExtras(); mRowId = extras != null ? extras.getLong(NotesDbAdapter.KEY_ROWID) : null; value = extras.getInt("key"); } I'm fairly sure that (mRowId == null) is not true when I'm using the createNote method so therefore getExtras won't be called. One of my questions would be how can I make my NoteEdit class get this value when I use the createNote method? I'm new to this so sorry if this is a simple question for you all. Thanks, Joe

  • ObjC get property name

    - by Joe Even
    Yes. I've searched a lot without success. I've looking for a way to get a property name as StringValue from inside a method. Lets say: My class has X Subviews from the Type UILabel. @property (strong, nonatomic) UILabel *firstLabel; @property (strong, nonatomic) UILabel *secondLabel; [...] and so on. Inside the method foo, the views are iterated as followed: -(void) foo { for (UIView *view in self.subviews) { if( [view isKindOfClass:[UILabel class]] ) { /* codeblock that gets the property name. */ } } } The Result should be something like that: THE propertyName(NSString) OF view(UILabel) IS "firstLabel" I've tried class_getInstanceVariable, object_getIvar and property_getName without Success. For Example, the Code for: [...] property_getName((void*)&view) [...] RETURNS: <UILabel: 0x6b768c0; frame = (65 375; 219 21); text = 'Something'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x6b76930>> But i'm looking for this kind of result: "firstLabel" , "secondLabel" and so on. Thanks for your help! Reagrds Joé

  • Custom Django Field is deciding to work as ForiegnKey for no reason

    - by Joe Simpson
    Hi, i'm making a custom field in Django. There's a problem while trying to save it, it's supposed to save values like this 'user 5' and 'status 9' but instead in the database these fields show up as just the number. Here is the code for the field: def find_key(dic, val): return [k for k, v in dic.items() if v == val][0] class ConnectionField(models.TextField): __metaclass__ = models.SubfieldBase serialize = False description = 'Provides a connection for an object like User, Page, Group etc.' def to_python(self, value): if type(value) != unicode: return value value = value.split(" ") if value[0] == "user": return User.objects.get(pk=value[1]) else: from social.models import connections return get_object_or_404(connections[value[0]], pk=value[1]) def get_prep_value(self, value): from social.models import connections print value, "prep" if type(value) == User: return "user %s" % str(value.pk) elif type(value) in connections.values(): o= "%s %s" % (find_key(connections, type(value)), str(value.pk)) print o, "return" return o else: print "CONNECTION ERROR!" raise TypeError("Value is not connectable!") Connection is just a dictionary with the "status" text linked up to the model for a StatusUpdate. I'm saving a model like this which is causing the issue: Relationship.objects.get_or_create(type="feedback",from_user=request.user,to_user=item) Please can someone help, Many Thanks Joe *_*

  • Trying to reconcile global ip address and Vhosts

    - by puk
    I have been using my local machine as a web server for a while, and I have several websites set up locally on my machine, all with similar Vhost files like the one seen here /etc/apache2/sites-available/john.smith.com: <VirtualHost *:80> RewriteEngine on RewriteOptions Inherit ServerAdmin [email protected] ServerName john.smith.com ServerAlias www.john.smith.com DocumentRoot /home/john/smith # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn LogFormat "%v %l %u %t \"%r\" %>s %b" comonvhost CustomLog /var/log/apache2/access.log comonvhost </VirtualHost> then I set up the /etc/hosts file like so for every Vhost: 192.168.1.100 www.john.smith.com john.smith.com 192.168.1.100 www.jane.smith.com jane.smith.com 192.168.1.100 www.joe.smith.com joe.smith.com 192.168.1.100 www.jimbob.smith.com jimbob.smith.com Now I am hosting my friend's website until he gets a permanent domain. I have port forwarding set up to redirect port 80 to my machine, but I don't understand how the global ip fits into all of this. Do I for example use the following web site addresses (assume global ip is 12.34.56.789): 12.34.56.789.john.smith 12.34.56.789.jane.smith 12.34.56.789.joe.smith 12.34.56.789.jimbob.smith

  • Asyncronus javascript rendering widgets

    - by Joe J
    Hey all, I'm creating a javascript widget so third partys (web designers) can post a link on their website and it will render the widget on their site. Currently, I'm doing this with just a script link tag: <div class="some_random_div_in_html_body"> <script type='text/javascript' src='http://remotehost.com/link/to/widget.js'></script> </div> However, this has the side-effect of slowing down a thrid party's website render times of the page if my site is under a load. Therefore, I'd like the third party website to request the widget link from my site asyncronously and then render it on their site when the widget link loads completely. The Google Analytics javascript snippet seems to have a nice bit of asyncronous code that does a nice async request to model off of, but I'm wondering if I can modify it so that it will render content on the third party's site. Using the example below, I want the content of http://mysite.com/link/to/widget.js to render something in the "message" id field. <HTML> <HEAD><TITLE>Third Party Site</TITLE><STYLE>#message { background-color: #eee; } </STYLE></HEAD> <BODY> <div id="message">asdf</div> <script type="text/javascript"> (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = 'http://mysite.com/link/to/widget.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); </script> </BODY> </HTML> I don't know if what I'm trying to do constitutes Cross Site Scripting (still a bit vague on that concept) but am wondering if what I'm trying to do is possible. Or if anyone has any other approaches to creating javascript widgets effectively, I'd appreciate any advice. Thanks for reading this. Joe

  • C Programming - My program is good enough for my assignment but I know its not good

    - by Joe
    Hi there I'm just starting an assignment for uni and it's raised a question for me. I don't understand how to return a string from a function without having a memory leak. char* trim(char* line) { int start = 0; int end = strlen(line) - 1; /* find the start position of the string */ while(isspace(line[start]) != 0) { start++; } //printf("start is %d\n", start); /* find the position end of the string */ while(isspace(line[end]) != 0) { end--; } //printf("end is %d\n", end); /* calculate string length and add 1 for the sentinel */ int len = end - start + 2; /* initialise char array to len and read in characters */ int i; char* trimmed = calloc(sizeof(char), len); for(i = 0; i < (len - 1); i++) { trimmed[i] = line[start + i]; } trimmed[len - 1] = '\0'; return trimmed; } as you can see I am returning a pointer to char which is an array. I found that if I tried to make the 'trimmed' array by something like: char trimmed[len]; then the compiler would throw up a message saying that a constant was expected on this line. I assume this meant that for some reason you can't use variables as the array length when initialising an array, although something tells me that can't be right. So instead I made my array by allocating some memory to a char pointer. I understand that this function is probably waaaaay sub-optimal for what it is trying to do, but what I really want to know is: 1. Can you normally initialise an array using a variable to declare the length like: char trimmed[len]; ? 2. If I had an array that was of that type (char trimmed[]) would it have the same return type as a pointer to char (ie char*). 3. If I make my array by callocing some memory and allocating it to a char pointer, how do I free this memory. It seems to me that once I have returned this array, I can't access it to free it as it is a local variable. Many thanks in advance Joe

  • How to specify the order of XmlAttributes, using XmlSerializer

    XmlElement has an "Order" attribute which you can use to specify the precise order of your properties (in relation to each other anyway) when serializing using XmlSerializer. Is there a similar thing for XmlAttribute? I just want to set the order of the attributes from something like <MyType end="bob" start="joe" /> to <MyType start="joe" end="bob" /> This is just for readability, my own benefit really.

  • javascript simple object creation test: opera leaks?

    - by joe
    Hi, I am trying to figure out certain memory leak conditions in javascript on a few browsers. Currently I'm only testing FF 3.6, Opera 10.10, and Safari 4.0.3. I've started with a fairly simple test, and can confirm no memory leaks in Firefox and Safari. But Opera just takes memory and never gives it back. What gives? Here's the test: <html> <head> <script type="text/javascript"> window.onload = init; //window.onunload = cleanup; var a=[]; function init() { var d = document.createElement('div'); d.innerHTML = "page loading..."; document.body.appendChild(d); for (var i=0; i<400000; i++) { a[i] = new Obj("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"); } d.innerHTML = "PAGE LOADED"; } function cleanup() { for (var i=0; i<400000; i++) { a[i] = null; } } function Obj(msg) { this.msg=msg; } </script> </head> <body> </body> </html> I shouldn't need the cleanup() call on window.unload, but tried that also. No luck. As you can see this is simple JS, no circular DOM links, no closures. I monitor the memory usage using 'top' on Mac 10.4.11. Memory usage spikes up on page load, as expected. In FF and Safari reloading the page does not use any further memory, and all memory is returned when the window (tab) is closed. In Opera, memory spikes on load, and seems to also spike further on each reload (but not always...). But regardless of reload, memory never goes back down below the initial load spike. I had hoped this was a no-brainer test that all browsers would pass, so I could move on to more "interesting" conditions. Am I doing something wrong here? Or is this a known Opera issue? Thanks! -joe

  • c++, object life-time of anonymous (unnamed) variables

    In the following code, the object constructed in the last line of 'main()', seems to be destroyed before the end of the expression. The destructor is called before the '<<' is executed.
