• Another answer to the CAPTCHA problem?

  - by Xeoncross

  Most sites at least employ server access log checking and banning along with some kind of bot prevention measure like a CAPTCHA (those messed-up text images). The problem with CAPTCHAs is that they poss a threat to the user experience. Luckily they now come with user friendly features like refresh and audio versions. Anyway, like linux vs windows, it isn't worth the time of a spammer to customize and/or build a script to handle a custom CAPTCHA example that only pertains to one site. Therefore, I was wondering if there might be better ways to handle the whole CAPTCHA thing. In A Better CAPTCHA Peter Bromberg mentions that one way would be to convert the image to HTML and display it embedded in the page. On http://shiflett.org/ Chris simply asks users to type his name into an input. Examples like this are ways to simplifying the CAPTCHA experience while decreasing the value for spammers. Does anyone know of more good examples I could use or see any problem with the embedded image idea?

• Convert matched string of UTF-8 values to UTF-8 characters in Ruby

  - by user1475154

  Trying to convert output from a rest_client GET to the characters that are represented with escape sequences. Input: ..."sub_id":"\u0d9c\u8138\u8134\u3f30\u8139\u2b71"... (which I put in 'all_subs') Match: m = /sub_id\"\:\"([^\"]+)\"/.match(all_subs.to_str) [1] Print: puts m.force_encoding("UTF-8").unpack('U*').pack('U*') But it just comes out the same way I put it in. ie, "\u0d9c\u8138\u8134\u3f30\u8139\u2b71" However, if I convert a raw string of it: puts "\u0d9c\u8138\u8134\u3f30\u8139\u2b71".unpack('U*').pack('U*') The output is perfect as "??????"

• Screen capture of MDI app with OpenGL graphics using MFC

  - by NPVN

  In our MDI application - which is written in MFC - we have a function to save a screenshot of the MDI client area to file. We are currently doing a BitBlt from the screen into a bitmap, which is then saved. The problem is that some of the MDI child windows have their content rendered by OpenGL, and in the destination bitmap these areas show up as blank or garbled. I have considered some alternatives: - Extract the OpenGL content directly (using glReadPixels), and draw this to the relevant portions of the screen bitmap. - Simulate an ALT+PrtScr, since doing this manually seems to get the content just fine. This will trash the clipboard content, though. - Try working with the DWM. Appart from Vista and Win7, this also needs to work on Win2000 and XP, so this probably isn't the way to go. Any input will be appreciated!

• StremReader.ReadToEnd() returning an empty string

  - by axk

  I have a method private static String DecompressAndDecode(byte[] data) { GZipStream decompressor = new GZipStream(new MemoryStream(data), CompressionMode.Decompress); StreamReader decompressed = new StreamReader(decompressor, Encoding.UTF8); String result = decompressed.ReadToEnd(); return result; } I have some GZipped text as input and the result is supposed to be a String representation of this text. The problem is that the method returns an empty string. What is puzzling me is that when I step trough the method in debug mode and reach the return statement the result variable is an empty string but if I create a watch for the decompressed.ReadToEnd() expression it returns me the text. What I would expect at this point is the result variable to contain the text and the decompressed.ReadToEnd() expression evaluating to an empty string. (Reevaluating the decompressed.ReadToEnd() expression returns an empty string as expected). There must be something obvious I'm missing here.

• Error Using PDCurses: Cannot Open File Libc.C

  - by cam

  I'm getting the error: 1>LINK : fatal error LNK1104: cannot open file 'LIBC.lib' Here's my source code: #include <curses.h> int main() { initscr(); /* Start curses mode */ printw("Hello World !!!"); /* Print Hello World */ refresh(); /* Print it on to the real screen */ getch(); /* Wait for user input */ endwin(); /* End curses mode */ return 0; } I've configured the PDcurses library properly (added to Additional Include libraries, added folder to Additional Library Directories). I've looked around for a bit, and I've tried adding Libc.C to the 'Ignore Library' list, which in turn causes about 150 errors. Not sure what to do from here.

• Want procmail to run a custom python script, everytime a new mail shows up

  - by Maddy

  I have a pretty usual requirement with procmail but I am unable to get the results somehow. I have procmailrc file with this content: :0 * ^To.*@myhost | /usr/bin/python /work/scripts/privilege_emails_forward.py Wherein my custom python script(privilege_emails_forward.py) will be scanning through the email currently received and do some operations on the mail content. But I am unable to get the script getting executed at the first shot(let alone scanning through the mail content). Is this a correct way of invoking an external program(python) as soon as new mail arrives? And how does my python program(privilege_emails_forward.py) will receive the mail as input? I mean as sys.argv or stdin????

  - by user355859

  is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified manifest.xml?? I know there are tools such as baksmali / smali to disassemble / re-assemble given classes.dex from .apk, but not sure limitation what could be modified from there on? I'm trying to add additional activity, to modify starting launcher activity (may be from androidmanifest.xml) from original apk, then re-pack and sign to make complete single .apk... all need to be done out of build time, no raw source or build structure visible, only .apk as input... ANY IDEA?

• FPDI - SELECT WHICH PDFS TO SHOW

  - by NORM

  IS THERE A WAY FOR A OPTION TO SELECT WHICH PDFS TO SHOW WITH THE FPDI FUNCTION? THIS IS THE REGULAR CODE: $pdf-AddPage(); // set the sourcefile $pdf-setSourceFile('h.pdf'); // import page 1 $tplIdx = $pdf-importPage(1); // use the imported page and place it at point 10,10 with a width of 100 mm $pdf-useTemplate($tplIdx, 0, 0, 0); Is there a way to make this $pdf-setSourceFile('h.pdf'); a option for users who visit the website. For example: have - $pdf-setSourceFile('h.pdf'); & $pdf-setSourceFile('g.pdf'); - then let the visitor select which one to include in the pdf via fpdi. I would prefer something like a input. Any ideas?? or something similar??? Help is very much appreciated!! :D

• Is there a mode for different Paypal IPN?

  - by Doug

  I have a donation script at this moment where the user inputs the donation amount on the Paypal website. The problem with this is that some people donate $0.30 which equates to $0 after Paypal fees. I want to put first check the amount donated using an input on my website and then send off the amount to the Paypal website where they can continue to enter their credit card information and what not. How do I do this? Do I have to change to another mode? or am I supposed to send the amount to Paypal and then they'll know how it's handled?

• Why does an onclick property set with setAttribute fail to work in IE?

  - by Aeon

  Ran into this problem today, posting in case someone else has the same issue. var execBtn = document.createElement('input'); execBtn.setAttribute("type", "button"); execBtn.setAttribute("id", "execBtn"); execBtn.setAttribute("value", "Execute"); execBtn.setAttribute("onclick", "runCommand();"); Turns out to get IE to run an onclick on a dynamically generated element, we can't use setAttribute. Instead, we need to set the onclick property on the object with an anonymous function wrapping the code we want to run. execBtn.onclick = function() { runCommand() }; BAD IDEAS: You can do execBtn.setAttribute("onclick", function() { runCommand() }); but it will break in IE in non-standards mode according to @scunliffe. You can't do this at all execBtn.setAttribute("onclick", runCommand() ); because it executes immediately, and sets the result of runCommand() to be the onClick attribute value, nor can you do execBtn.setAttribute("onclick", runCommand);

• Retrieve Button value with jQuery

  - by Simon Hutton

  A simple one, I'm trying to retrieve the value attribute of a button when its been pressed using jQuery, here's what I have: <script type="text/javascript"> $(document).ready(function() { $('.my_button').click(function() { alert($(this).val()); }); }); </script> <button class="my_button" name="buttonName" value="buttonValue"> Button Label</button> In Firefox my alert displays 'buttonValue' which is great but in IE7 it displays 'Button Label'. What jQuery should I use to always get the button's value? Or should I be using a different approach? Many thanks. ANSWER: I'm now using <input class="my_button" type="image" src="whatever.png" value="buttonValue" />

• How to draw a sliced image in Cairo?

I have tried rendering to both xlib and png surfaces, neither seems to work, that is nothing is drawn. Also, I have written the input surfaces to png files, and they appear to be working. Thanks.

• JQuery Scrollable List Dissapears if scrolled IE7

  - by namtax

  Hi there I have created a time picker using jquery, using the following code // Display Time Picker $('.time').click(function(){ $('.timePicker').remove(); var thisTime = $(this); var timePicker = '<ul class="timePicker">' timePicker += '<li>09:00</li>' timePicker += '<li>09:15</li>' timePicker += '</ul>' thisTime.after(timePicker); $('.timePicker').fadeIn() $('.timePicker li').click(function(){ term = $(this).html(); $(thisTime).val(term); $('.timePicker').remove(); }); }).blur(function(){ $('.timePicker').fadeOut(); }); This adds a dropdown scrollable list of times to any input field with the class "time". This functions as expected in all browsers apart from IE7, where if I scroll the list to choose a time lower down in the list, the list dissapears.. Hope that makes sense, any help would be much appreciated Many thanks

• PHP getopt Operations

  - by Rachel

  This question is regarding getopt function in php. I need to pass two parameter to the php scripts like php script.php -f filename -t filetype Now depending upon the file type which can be u, c or s I need to do proper operation. I am using switch case for the same: Here is the Code I am using: // Get filename of input file when executing through command line. $file = getopt("f:t:"); Switch case should compare the type of the file which I am passing in from the command line (u, c or i) and accordingly match it and do the operation. switch("I am not sure what should go in there and this is wrong,Please advice") { case `Not sure`: $p->ini(); break; case `Not sure`: $p->iniCon(); break; case `Not sure`: $p->iniImp(); break; } Kindly advise on this !!!

• C# Monitor Programs Periodically Based on PID

  - by ThaKidd

  Thank you in advance for you ideas and input. I would like to periodically check to see if a third party program is currently running on a user's system from my program. I am currently launching the program as follows in C#: String plinkConString = ""; // my connection string Process plink = Process.Start(utilityPath + @"\putty.exe", plinkConString); int plinkProcessId = plink.Id; I launch the program and grab its pid in a Windows environment. As Putty/PLink may disconnect from its SSH server at some point and close, what is the best way to monitor how this process is doing in code? Is there a better way to launch this program to monitor its success or failure?

• jQuery Event Keypress: Which key was pressed?

  - by BlaM

  With jQuery, how do I find out which key was pressed when I bind to the keypress event? $('#searchbox input').bind('keypress', function(e) {}); I want to trigger an submit when ENTER is pressed. [Update] Even though I found the (or better: one) answer myself, there seems to be some room for variation ;) Is there a difference between keyCode and which - especially if I'm just looking for ENTER, which will never be a unicode key? Do some browsers provide one property and others provide the other one?

• SQL: How can i update a value on a column only if that value is null?

  - by user321185

  Hey, I have an SQL question which may be basic to some but is confusing me. Here is an example of column names for a table 'Person': PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood Let's say that I input the row: 121312, Rayna, Pieterson, BMW123d, Brown, NULL, NULL Now I want to update the values for this person, but only if the new value is not null, Update: 121312, Rayna, Pieterson, NULL, Blonde, Fanta, NULL The new row needs to be: 121312, Rayna, Pieterson, BMW123d, Blonde, Fanta, NULL So I was thinking something along the lines of: Update Person(PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood) set Car = @Car (where @Car is not null), HairColour = @HairColour (where @HairColour...)... etc. My only concern is that I can't group all the conditions at the end of the query because it will require all the values to have the same condition. Can't i do something like Update HairColour if @HairColour is not Null

• Nested form using accepts_nested_attributes_for with pre-population from another table

  - by mikeydelamonde

  I'm using Rails 2.3.5 and have a nested structure as follows: Lists has_many Items Items_Features has_many Features Items_Features has_many Items Items_Features has a text field to hold the value of the feature Then I have a nested form with partials to update and display this so that it updates Lists, Items and Items_Features What I want to do is generate input fields for each of the rows in features so that the user can fill in a value and it gets inserted/updated in items_features. I also want a label next to the box to display the feature name. It might look like this: List name: Cheeses Item1 name: Edam Feature, hardness: - fill in - <= this list of features from feature table Feature, smell: - fill in - How can I interrupt the nice and easy accepts_nested_attributes_for system to display this as I want?

• Trying to parse xml, but xmldocument.loadxml() is trying to download?

  - by maxp

  I have a string input that i do not know whether or not is valid xml. I think the simplest aprroach is to wrap new XmlDocument().LoadXml(strINPUT); In a try/catch. The problem im facing is, sometimes strINPUT is an html file, if the header of this file contains <!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""> <html xml:lang=""en-GB"" xmlns=""http://www.w3.org/1999/xhtml"" lang=""en-GB""> ...like many do, it actually tries to make a connection to the w3.org url, which i really dont want it doing. Anyone know if its possible to just parse the string without trying to be clever and checking external urls? Failing that is there an alternative to xmldocument?

• disable text drag and drop

  - by maniek

  There is a common feature of modern browsers where a user can select some text and drag it to an input field. Within the same field it causes moving of text, between different fields it does copying. How do I disable that? If there is no portable way, I am mostly interested in firefox. This is an intranet webapp, so I am also interested in modifying the browser/getting a plugin to do this. Maybe some system-level settings (I`m on windows XP)? I need to keep the default select-copy-paste functionality. The background is I have multiple-field data entry forms, and users often drag something by mistake.

• Django: Geocoding an address on form submission?

  - by User

  Trying to wrap my head around django forms and the django way of doing things. I want to create a basic web form that allows a user to input an address and have that address geocoded and saved to a database. I created a Location model: class Location(models.Model): address = models.CharField(max_length=200) city = models.CharField(max_length=100) state = models.CharField(max_length=100, null=True) postal_code = models.CharField(max_length=100, null=True) country = models.CharField(max_length=100) latitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) longitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) And defined a form: class LocationForm(forms.ModelForm): class Meta: model = models.Location exclude = ('latitude','longitude') In my view I'm using form.save() to save the form. This works and saves an address to the database. I created a module to geocode an address. I'm not sure what the django way of doing things is, but I guess in my view, before I save the form, I need to geocode the address and set the lat and long. How do I set the latitude and longitude before saving?
