  • 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

  • Does correcting a value in an validation method mark the object as dirty?

    - by dontWatchMyProfile
    From the docs: If you change the input value in a validate:error: method, you must ensure that you only change the value if it is invalid or uncoerced. The reason is that, since the object and context are now dirtied, Core Data may validate that key again later. If you keep performing a coercion in a validation method, this can therefore produce an infinite loop. So when I modify a value in a validation method, the context gets dirtied? And the next time I save, the validation happens again - and when I change the value even if the validation is OK, then the context is again dirtied, and revalidated again - and I change the value, and Core Data validates, again, because the context is dirtied. And so on...for ever... is that right? Or did they try to say something different?

  • Java URLConnection Timeout

    - by Chris
    I am trying to parse an XML file from an HTTP URL. I want to configure a timeout of 15 seconds if the XML fetch takes longer than that, I want to report a timeout. For some reason, the setConnectTimeout and setReadTimeout do not work. Here's the code: URL url = new URL("http://www.myurl.com/sample.xml"); URLConnection urlConn = url.openConnection(); urlConn.setConnectTimeout(15000); urlConn.setReadTimeout(15000); urlConn.setAllowUserInteraction(false); urlConn.setDoOutput(true); InputStream inStream = urlConn.getInputStream(); InputSource input = new InputSource(inStream); And I am catching the SocketTimeoutException. Thanks Chris

  • Python: Trying to get index of an intersection

    - by user1620716
    I have the following line of code: for i in [i for i,x in enumerate(catdate) if x == set(NNSRCfile['datetimenew']).intersection(catdate)]: print i I am trying to find the index of the intersection for the two components above. Both are lengthy lists that have several commonalities. The intersection part works perfectly; however, the for loop seems to output nothing. (ie: there is nothing that is printed). Python outputs no error, and when I run the code in IPython, I notice that i is equivalent to to the very last element in the list "catdate", instead of listing the indices of "catdate" that are equivalent to the intersection values. Any help is greatly appreciated!

Please explain.

  • 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?

  • oracle plsql: retrieve runtime parameter values when you call a procedure

    - by Luca Vaccaro
    I need a generalized method to get list of runtime parameters (values) when I call a procedure. I need something similar to the $$PLSQL_UNIT that returns the name of the running procedure. (plsql Oracle 10g) E.g. look at this sample procedure: (it simply prints its own name and parameters ) CREATE OR REPLACE PROCEDURE MY_PROC(ow in varchar2, tn IN varchar2) IS BEGIN dbms_output.put_line('proc_name: '||$$PLSQL_UNIT||' parameters: '|| ow||' '||tn ); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('ERRORE: ' ||SQLERRM); END MY_PROC; / Running procedure produces the following output: SQL> 1 BEGIN 2 IBAD_OWN.MY_PROC('first_par', 'second_par'); 3 END; 4 / proc_name: MY_PROC parameters: first_par second_par PL/SQL procedure successfully completed. I'm not satisfy because I can't copy and paste in all my procedures because I have to hard code each procedure to set their right parameter variables. Thanks in advance for the help.

  • How does Microsoft Detours work and how do I use it to get a stack trace?

    - by Bruce
    I am new to Microsoft Detours. I have installed it to trace the system calls a process makes. I run the following commands which I got from the web syelogd.exe /q C:\Users\xxx\Desktop\log.txt withdll.exe /d:traceapi.dll C:\Program Files\Google\Google Talk\googletalk.exe I get the log file. The problem is I don't fully understand what is happening here. How does detours work? How does it trace the system calls? Also I don't know how to read the output in log.txt. Here is one line in log.txt 20101221060413329 2912 50.60: traceapi: 001 GetCurrentThreadId() Finally I want to get the stack trace of the process. How can I get that?

  • Best way to save complex Python data structures across program sessions (pickle, json, xml, database

    - by Malcolm
    Looking for advice on the best technique for saving complex Python data structures across program sessions. Here's a list of techniques I've come up with so far: pickle/cpickle json jsonpickle xml database (like SQLite) Pickle is the easiest and fastest technique, but my understanding is that there is no guarantee that pickle output will work across various versions of Python 2.x/3.x or across 32 and 64 bit implementations of Python. Json only works for simple data structures. Jsonpickle seems to correct this AND seems to be written to work across different versions of Python. Serializing to XML or to a database is possible, but represents extra effort since we would have to do the serialization ourselves manually. Thank you, Malcolm

  • US (Postal) ZIP codes: ZIP+4 vs. ZIP in web applications

    - by FreekOne
    Hi guys, I am currently writing a web application intended for US users that asks them to input their ZIP code and I just found out about the ZIP+4 code. Since I am not from the US and getting a user's correct ZIP code is important, I have no idea which format I should use. Could anyone (preferably from the US) please clarify what's the deal with the +4 digits and how important are they ? Is it safe to use only the plain 5-digit ZIP ? Thank you in advance !

  • 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.

  • Disable buttons on post back using jquery in .net app

    - by Chris Lively
    I have a asp.net app that I want to disable the buttons as soon as they are clicked in order to prevent multiple submissions. I'd like to use jquery for this as the site already liberally uses it anyway. What I've tried is: $(document).ready(function () { $("#aspnetForm").submit(function () { $('input[type=submit]', $(this)).attr("disabled", "disabled"); }) }); The above will disable the button, and the page submits, but the asp.net button on click handler is never called. Simply removing the above and the buttons work as normal. Is there a better way?

  • directx 9 hlsl vs. directx 10 hlsl : syntex the same.

    - by numerical25
    For the past month or so I been busting my behind trying to learn directx. So I been mixing back back and fourth from directx 9 to directx 10. One of the major changes I've seen in the two is how to process vectors in the graphics card. one of the drastic changes I notice is how you get the gpu to recognize your structs. In directx 9 you define the Flexible Vertex Formats your typical set up would be like this... #define CUSTOMFVF (D3DFVF_XYZRHW | D3DFVF_DIFFUSE) in directx 10 I believe the equivalent is the input vertex description D3D10_INPUT_ELEMENT_DESC layout[] = { {"POSITION",0,DXGI_FORMAT_R32G32B32_FLOAT, 0 , 0, D3D10_INPUT_PER_VERTEX_DATA, 0}, {"COLOR",0,DXGI_FORMAT_R32G32B32A32_FLOAT, 0 , 12, D3D10_INPUT_PER_VERTEX_DATA, 0} }; I notice in directx 10. it is more descriptive. besides this, what are some of the drastic changes made. and is the hlsl syntax the same for both.

  • Using Ant to merge two different properties files

    - by Justin
    I have a default properties file, and some deployment specific properties files that override certain settings from the default, based on deployment environment. I would like my Ant build script to merge the two properties files (overwriting default values with deployment specific values), and then output the resulting properties to a new file. I tried doing it like so but I was unsuccessful: <target depends="init" name="configure-target-environment"> <filterset id="application-properties-filterset"> <filtersfile file="${build.config.path}/${target.environment}/application.properties" /> </filterset> <copy todir="${web-inf.path}/conf" file="${build.config.path}/application.properties" overwrite="true" failonerror="true" > <filterset refid="application-properties-filterset" /> </copy> </target>

  • datetime command line argument in python 2.4

    - by Ike Walker
    I want to pass a datetime value into my python script on the command line. My first idea was to use optparse and pass the value in as a string, then use datetime.strptime to convert it to a datetime. This works fine on my machine (python 2.6), but I also need to run this script on machines that are running python 2.4, which doesn't have datetime.strptime. How can I pass the datetime value to the script in python 2.4? Here's the code I'm using in 2.6: parser = optparse.OptionParser() parser.add_option("-m", "--max_timestamp", dest="max_timestamp", help="only aggregate items older than MAX_TIMESTAMP", metavar="MAX_TIMESTAMP(YYYY-MM-DD HH24:MM)") options,args = parser.parse_args() if options.max_timestamp: # Try parsing the date argument try: max_timestamp = datetime.datetime.strptime(options.max_timestamp, "%Y-%m-%d %H:%M") except: print "Error parsing date input:",sys.exc_info() sys.exit(1)

  • 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 !!!

  • 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" />

  • asp.net mvc custom routes with multiple submit buttons

    - by dangerisgo
    So I have a custom route as such: routes.MapRoute( "Wizard", // Route name "Wizard/{page}", // URL with parameters new { controller = "Wizard", action = "Index" } // Parameter defaults ); and have the following on my View: <% Html.BeginForm("Continue", "Wizard"); %> <input type="submit" value="Continue" name="Continue" /> <% Html.EndForm(); %> In which I want to call this function: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Continue(string Number, string Rev) { (...) } but in turn when that button is pressed always calls the postback Index rather than the one I want. If I remove the custom route, it calls my function, but what I want to be displayed in the address bar is: localhost:xxxx/Wizard/1 where the number at the end is the page (div shown) of the wizard either 1, 2, 3, or 4. So is there something I'm missing or can it not be done? Thanks.
