  • SIMPLE PHP MVC Framework!

    - by Allen
    I need a simple and basic MVC example to get me started. I dont want to use any of the available packaged frameworks. I am in need of a simple example of a simple PHP MVC framework that would allow, at most, the basic creation of a simple multi-page site. I am asking for a simple example because I learn best from simple real world examples. Big popular frameworks (such as code ignighter) are to much for me to even try to understand and any other "simple" example I have found are not well explained or seem a little sketchy in general. I should add that most examples of simple MVC frameworks I see use mod_rewrite (for URL routing) or some other Apache-only method. I run PHP on IIS. I need to be able to understand a basic MVC framework, so that I could develop my own that would allow me to easily extend functionality with classes. I am at the point where I understand basic design patterns and MVC pretty well. I understand them in theory, but when it comes down to actually building a real world, simple, well designed MVC framework in PHP, i'm stuck. I would really appreciate some help! Edit: I just want to note that I am looking for a simple example that an experienced programmer could whip up in under an hour. I mean simple as in bare bones simple. I dont want to use any huge frameworks, I am trying to roll my own. I need a decent SIMPLE example to get me going.

  • Writing to EEPROM on PIC

    - by JB
    Are there any PIC microcontroller programmers here? I'm learning some PIC microcontroller programming using a pickit2 and the 16F690 chip that came with it. I'm working through trying out the various facilities at the moment. I can sucessfully read a byte from the EEPROM in code if I set the EEPROM vaklue in MPLAB but I don't seem to be able to modify the value using the PIC itsself. Simply nothing happens and I don't read back the modified value, I always get the original which implies to me that the write isn't working? This is my code for that section, am I missing something? I know I'm doing a lot of unnecessary bank switches, I added most of them to ensure that being on the wrong bank wasn't the issue. ; ------------------------------------------------------ ; Now SET the EEPROM location ZERO to 0x08 ; ------------------------------------------------------ BANKSEL EEADR CLRF EEADR ; Set EE Address to zero BANKSEL EEDAT MOVLW 0x08 ; Store the value 0x08 in the EEPROM MOVWF EEDAT BANKSEL EECON1 BSF EECON1, WREN ; Enable writes to the EEPROM BANKSEL EECON2 MOVLW 0x55 ; Do the thing we have to do so MOVWF EECON2 ; that writes can work MOVLW 0xAA MOVWF EECON2 BANKSEL EECON1 BSF EECON1, WR ; And finally perform the write WAIT BTFSC EECON1, WR ; Wait for write to finish GOTO WAIT BANKSEL PORTC ; Just to make sure we are on the right bank

  • looking for a license key algorithm.

    - by giulio
    There are a lot of questions relating to license keys asked on stackoverflow. But they don't answer this question. Can anyone provide a simple license key algorithm that is technology independent and doesn't required a diploma in mathematics to understand ? The license key algorithm is similar to public key encryption. I just need something simple that can be implemented in any platform .Net/Java and uses simple data like characters. Preferably no byte translations required. So if a person presents a string, a complementary string can be generated that is the authorisation code. Below is a common scenario that it would be used for. Customer downloads s/w which generates a unique key upon initial startup/installation. S/w runs during trial period. At end of trial period an authorisation key is required. Customer goes to designated web-site, enters their code and get authorisation code to enable s/w, after paying :) Don't be afraid to describe your answer as though you're talking to a 5 yr old as I am not a mathemtician. Just need a decent basic algorithm, we're not launching nukes... NB: Please no philosophy on encryption nor who is Diffie-Hellman. I just need a basic solution.

  • Titanium Appcelerator - After enabling cloud services I get UnicodeDecodeError when compiling for Android

    - by Shahar Zrihen
    I've got an app that has a UTF8 name (hebrew). I use the platform/android/AndroidManifest.xml file for this. I've managed to narrow it down to the Ti.cloudpush module. only when I enable this module I get the error. I used to be able to compile it to android without any issues but as soon as I enable cloud services I get this error - [ERROR] Exception occured while building Android project: [ERROR] Traceback (most recent call last): [ERROR] File "/Users/Shahar/Library/Application Support/Titanium/mobilesdk/osx/2.1.0.GA/android/builder.py", line 2218, in <module> [ERROR] s.build_and_run(True, None, key, password, alias, output_dir) [ERROR] File "/Users/Shahar/Library/Application Support/Titanium/mobilesdk/osx/2.1.0.GA/android/builder.py", line 1970, in build_and_run [ERROR] self.manifest_changed = self.generate_android_manifest(compiler) [ERROR] File "/Users/Shahar/Library/Application Support/Titanium/mobilesdk/osx/2.1.0.GA/android/builder.py", line 1195, in generate_android_manifest [ERROR] custom_manifest_contents = fill_manifest(custom_manifest_contents) [ERROR] File "/Users/Shahar/Library/Application Support/Titanium/mobilesdk/osx/2.1.0.GA/android/builder.py", line 1122, in fill_manifest [ERROR] manifest_source = manifest_source.replace(ti_permissions,permissions_required_xml) [ERROR] UnicodeDecodeError: 'ascii' codec can't decode byte 0xd7 in position 501: ordinal not in range(128) and this is my manifest file with the part that causes the issues.

  • How to retrieve an array from Multidimensional Array.

    - by Mike Smith
    So I have a multi-dimensional array looks like this. $config = array( "First Name" => array( "user" => $_POST['firstname'], "limit" => 35, ), "Last Name" => array( "user" => $_POST['lastname'], "limit" => 40, ), ); I want use the array that's within the config array, so my approach is to use a foreach loop. foreach($config as $field => $data) { } Now I know that $data will be my array, but it seems I can't use it outside of the foreach statement because I only get half of whats already there. Using print_r you can see what it shows outside the loop: Array ( [user] => lastname [limit] => 40 ) But when inside the loop and I use print_r here is my result: Array ( [user] => firstname [limit] => 35 ) Array ( [user] => lastname [limit] => 40 ) I imagine it has to do something with it being with the foreach loop. I've tried to run a foreach on the $data array to populate another array, but that didn't work as well. Is there a way to use this outside of a foreach loop? Sorry if this a dumb question, I'm sure there is a quite a simple answer to this, but I'm just stumped, and can't think of a way to do this. Thanks.

  • Retrieve Flash file post in ASP.NET

    - by Quandary
    Question: In ASP.NET, I retrieve a JPEG-file as Flash post data like this Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest context.Response.ContentType = "text/plain" ' Retrieve a bytearray from the post buffer Dim myBuffer As Byte() = context.Request.BinaryRead(Convert.ToInt32(context.Request.InputStream.Length)) System.IO.File.WriteAllBytes("c:\temp\test.jpg", myBuffer) End Sub In Flash, I send it to an asp.net handler like this var jpgSource:BitmapData = cPrint.TakeSnapshot(MovieClip(cGlobals.ccPlanZoomView)); var bmpThisBitmap:Bitmap = new Bitmap(jpgSource); var nQuality:Number = 100; var jpgEncoder:JPGEncoder = new JPGEncoder(nQuality); var jpgStream:ByteArray = jpgEncoder.encode(jpgSource); var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream"); // Make sure to use the correct path to jpg_encoder_download.php var strFileName:String="test.jpg"; var jpgURLRequest:URLRequest = new URLRequest("http://localhost/raumplaner_new/raumplaner_new/cgi-bin/SavePDF.ashx"); //var scriptVars:URLVariables = new URLVariables(); //scriptVars.fn = strFileName; //var myarr:Array= new Array(); //myarr.push(jpgStream); //scriptVars.Files = myarr; jpgURLRequest.requestHeaders.push(header); jpgURLRequest.method = URLRequestMethod.POST; //jpgURLRequest.data = scriptVars; jpgURLRequest.data = jpgStream; var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.BINARY; loader.load(jpgURLRequest); It works but I want to send a few additional variables along, via scriptVars (commented out here). How do I retrieve the JPEG file in that case ? Because if I use parameters, there is no more BinaryRead... Aspecially, how would I read an array of jpeg files (several files) ?

  • Linking problems using libcurl with Visual C++ 2005: "unresolved external symbol __imp__curl_easy_se

    - by user88595
    Hi, I am planning to use libcurl in my project. I had downloaded the library source,built and integrated it in a small POC application. I am able to build and run the application without any issues with the generated libcurl.dll and libcurl_imp.lib files. Now when I integrate the same library in my project I am getting linker errors. 6foo.obj : error LNK2001: unresolved external symbol _imp_curl_easy_setopt 6foo.obj : error LNK2001: unresolved external symbol _imp_curl_easy_perform 6foo.obj : error LNK2001: unresolved external symbol _imp_curl_easy_cleanup 6foo.obj : error LNK2001: unresolved external symbol _imp_curl_global_init 6foo.obj : error LNK2001: unresolved external symbol _imp_curl_easy_init I have researched and tried all manners of workarounds like adding CURL_STATICLIB definitions , additional libraries , changing to /MT even copying the libs to the release directory but nothing seems to work. As far as I can see the only difference between approach #1 and #2 in my steps are #1 is an console application using the libcurl.dll while in my main project this is another dll which is trying to link to libcurl.dll.. Would that necessitate any change in approach? Can I use the same generated multi threaded DLL /MD file for both(Tried /MT also with no success)? Any other ideas? Following are the linker options. -------------------------------------------------Working------------------------------------------------- /OUT:"C:\SampleFTP\Release\SampleFTP.exe" /INCREMENTAL:NO /NOLOGO /LIBPATH:"C:\SampleFTP\SampleFTP\Release" /MANIFEST /MANIFESTFILE:"Release\SampleFTP.exe.intermediate.manifest" /DEBUG /PDB:"c:\SampleFTP\release\SampleFTP.pdb" /SUBSYSTEM:CONSOLE /OPT:REF /OPT:ICF /LTCG /MACHINE:X86 /ERRORREPORT:PROMPT libcurl_imp.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib -------------------------------------------------Working------------------------------------------------- ----------------------------------------------NotWorking------------------------------------------------- /OUT:".......\nt\Win32\Release/foo__tests.dll" /INCREMENTAL:NO /NOLOGO /LIBPATH:"C:\FullLibPath\libcurl_libs" /LIBPATH:"......\nt\Win32\Release" /DLL /MANIFEST /MANIFESTFILE:".\foo_tests\Win32\Release\foo_tests.dll.intermediate.manifest" /DEBUG /PDB:".......\nt\Win32\Release/foo_tests.pdb" /OPT:REF /OPT:ICF /LTCG /IMPLIB:".......\nt\Win32\Release/foo_tests.lib" /MACHINE:X86 /ERRORREPORT:PROMPT odbc32.lib odbccp32.lib util_process.lib wsock32.lib Version.lib libcurl_imp.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib "......\nt\win32\release\otherlib1.lib" "......\nt\win32\release\otherlib2.lib" ----------------------------------------------NotWorking-------------------------------------------------

  • How to Display a Bmp in a RTF control in VB.net

    - by Gerolkae
    I Started with this C# Question I'm trying to Display a bmp image inside a rtf Box for a Bot program I'm making. This function is supposed to convert a bitmap to rtf code whis is inserted to another rtf formatter srtring with additional text. Kind of like Smilies being used in a chat program. For some reason the output of this function gets rejected by the RTF Box and Vanishes completly. I'm not sure if it the way I'm converting the bmp to a Binary string or if its tied in with the header tags 'returns the RTF string representation of our picture Public Shared Function PictureToRTF(ByVal Bmp As Bitmap) As String Dim stream As New MemoryStream() Bmp.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp) Dim bytes As Byte() = stream.ToArray() Dim str As String = BitConverter.ToString(bytes, 0).Replace("-", String.Empty) 'header to string we want to insert Using g As Graphics = Main.CreateGraphics() xDpi = g.DpiX yDpi = g.DpiY End Using Dim _rtf As New StringBuilder() ' Calculate the current width of the image in (0.01)mm Dim picw As Integer = CInt(Math.Round((Bmp.Width / xDpi) * HMM_PER_INCH)) ' Calculate the current height of the image in (0.01)mm Dim pich As Integer = CInt(Math.Round((Bmp.Height / yDpi) * HMM_PER_INCH)) ' Calculate the target width of the image in twips Dim picwgoal As Integer = CInt(Math.Round((Bmp.Width / xDpi) * TWIPS_PER_INCH)) ' Calculate the target height of the image in twips Dim pichgoal As Integer = CInt(Math.Round((Bmp.Height / yDpi) * TWIPS_PER_INCH)) ' Append values to RTF string _rtf.Append("{\pict\wbitmap0") _rtf.Append("\picw") _rtf.Append(Bmp.Width.ToString) ' _rtf.Append(picw.ToString) _rtf.Append("\pich") _rtf.Append(Bmp.Height.ToString) ' _rtf.Append(pich.ToString) _rtf.Append("\wbmbitspixel24\wbmplanes1") _rtf.Append("\wbmwidthbytes40") _rtf.Append("\picwgoal") _rtf.Append(picwgoal.ToString) _rtf.Append("\pichgoal") _rtf.Append(pichgoal.ToString) _rtf.Append("\bin ") _rtf.Append(str.ToLower & "}") Return _rtf.ToString End Function

  • Run a .java file using ProcessBuilder

    - by David K
    I'm a novice programmer working in Eclipse, and I need to get multiple processes running (this is going to be a simulation of a multi-computer system). My initial hackup used multiple threads to multiple classes, but now I'm trying to replace the threads with processes. From my reading, I've gleaned that ProcessBuilder is the way to go. I have tried many many versions of the input you see below, but cannot for the life of me figure out how to properly use it. I am trying to run the .java files I previously created as classes (which I have modified). I eventually just made a dummy test.java to make sure my process is working properly - its only function is to print that it ran. My code for the two files are below. Am I using ProcessBuilder correctly? Is this the correct way to read the output of my subprocess? Any help would be much appreciated. David primary process package Control; import java.io.*; import java.lang.*; public class runSPARmatch { /** * @param args */ public static void main(String args[]) { try { ProcessBuilder broker = new ProcessBuilder("javac.exe","test.java","src\\Broker\\"); Process runBroker = broker.start(); Reader reader = new InputStreamReader(runBroker.getInputStream()); int ch; while((ch = reader.read())!= -1) System.out.println((char)ch); reader.close(); runBroker.waitFor(); System.out.println("Program complete"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } subprocess package Broker; public class test { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub System.out.println("This works"); } }

  • Filtering Wikipedia's XML dump: error on some accents

    - by streetpc
    I'm trying to index Wikpedia dumps. My SAX parser make Article objects for the XML with only the fields I care about, then send it to my ArticleSink, which produces Lucene Documents. I want to filter special/meta pages like those prefixed with Category: or Wikipedia:, so I made an array of those prefixes and test the title of each page against this array in my ArticleSink, using article.getTitle.startsWith(prefix). In English, everything works fine, I get a Lucene index with all the pages except for the matching prefixes. In French, the prefixes with no accent also work (i.e. filter the corresponding pages), some of the accented prefixes don't work at all (like Catégorie:), and some work most of the time but fail on some pages (like Wikipédia:) but I cannot see any difference between the corresponding lines (in less). I can't really inspect all the differences in the file because of its size (5 GB), but it looks like a correct UTF-8 XML. If I take a portion of the file using grep or head, the accents are correct (even on the incriminated pages, the <title>Catégorie:something</title> is correctly displayed by grep). On the other hand, when I rectreate a wiki XML by tail/head-cutting the original file, the same page (here Catégorie:Rock par ville) gets filtered in the small file, not in the original… Any idea ? Alternatives I tried: Getting the file (commented lines were tried wihtout success): FileInputStream fis = new FileInputStream(new File(xmlFileName)); //ReaderInputStream ris = ReaderInputStream.forceEncodingInputStream(fis, "UTF-8" ); //(custom function opening the stream, reading it as UFT-8 into a Reader and returning another byte stream) //InputSource is = new InputSource( fis ); is.setEncoding("UTF-8"); parser.parse(fis, handler); Filtered prefixes: ignoredPrefix = new String[] {"Catégorie:", "Modèle:", "Wikipédia:", "Cat\uFFFDgorie:", "Mod\uFFFDle:", "Wikip\uFFFDdia:", //invalid char "Catégorie:", "Modèle:", "Wikipédia:", // UTF-8 as ISO-8859-1 "Image:", "Portail:", "Fichier:", "Aide:", "Projet:"}; // those last always work

  • Problem Linking Boost Filesystem Library in Microsoft Visual C++

    - by Scott
    Hello. I am having trouble getting my project to link to the Boost (version 1.37.0) Filesystem lib file in Microsoft Visual C++ 2008 Express Edition. The Filesystem library is not a header-only library. I have been following the Getting Started on Windows guide posted on the official boost web page. Here are the steps I have taken: I used bjam to build the complete set of lib files using: bjam --build-dir="C:\Program Files\boost\build-boost" --toolset=msvc --build-type=complete I copied the /libs directory (located in C:\Program Files\boost\build-boost\boost\bin.v2) to C:\Program Files\boost\boost_1_37_0\libs. In Visual C++, under Project Properties Additional Library Directories I added these paths: C:\Program Files\boost\boost_1_37_0\libs C:\Program Files\boost\boost_1_37_0\libs\filesystem\build\msvc-9.0express\debug\link-static\threading-multi I added the second one out of desperation. It is the exact directory where libboost_system-vc90-mt-gd-1_37.lib resides. In Configuration Properties C/C++ General Additional Include Directories I added the following path: C:\Program Files\boost\boost_1_37_0 Then, to put the icing on the cake, under Tools Options VC++ Directories Library files, I added the same directories mentioned in step 3. Despite all this, when I build my project I get the following error: fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-gd-1_37.lib' Additionally, here is the code that I am attempting to compile as well as a screen shot of the aformentioned directory where the (assumedly correct) lib file resides: #include "boost/filesystem.hpp" // includes all needed Boost.Filesystem declarations #include <iostream> // for std::cout using boost::filesystem; // for ease of tutorial presentation; // a namespace alias is preferred practice in real code using namespace std; int main() { cout << "Hello, world!" << endl; return 0; } Can anyone help me out? Let me know if you need to know anything else. As always, thanks in advance.

  • Finding Common Phrases in SQL Server TEXT Column

    - by regex
    Short Desc: I'm curious to see if I can use SQL Analysis services or some other SQL Server service to mine some data for me that will show commonalities between SQL TEXT fields in a dataset. Long Desc I am looking at a subset of data that consists of about 10,000 rows of TEXT blobs which are used as a notes column in a issue tracking (ticketing) software. I would like to use something out of the box (without having to build something) that might be able to parse through all of the rows and find commonly used byte sequences in the "Notes" column. In other words, I want to find commonly used phrases (two to three word phrases, so 9 - 20 character sections of the TEXT blob). This will help me better determine if associate's notes contain similar phrases (troubleshooting techniques) that we could standardize in our troubleshooting process flow. Closing Note I'd really rather not build an application to do this as my method will probably not be the most efficient way to do it. Hopefully all this makes sense. Please let me know in the comments if anything needs clarification.

  • Uncatchable AccesViolationException

    - by Roy
    Hi all, I'm getting close to desperate.. I am developing a field service application for Windows Mobile 6.1 using C# and quite some p/Invoking. (I think I'm referencing about 50 native functions) On normal circumstances this goes without any problem, but when i start stressing the GC i'm getting a nasty 0xC0000005 error witch seems uncatchable. In my test i'm rapidly closing and opening a dialog form (the form did make use of native functions, but for testing i commented these out) and after a while the Windows Mobile error reporter comes around to tell me that there was an fatal error in my application. My code uses a try-catch around the Application.Run(masterForm); and hooks into the CurrentDomain.UnhandledException event, but the application still crashes. Even when i attach the debugger, visual studio just tells me "The remote connection to the device has been lost" when the exception occurs.. Since I didn't succeed to catch the exception in the managed environment, I tried to make sense out of the Error Reporter log file. But this doesn't make any sense, the only consistent this about the error is the application where it occurs in. The thread where the application occurs in is unknown to me, the module where the error occurs differs from time to time (I've seen my application.exe, WS2.dll, netcfagl3_5.dll and mscoree3_5.dll), even the error code is not always the same. (most of the time it's 0xC0000005, but i've also seen an 0X80000002 error, which is a warning accounting the first byte?) I tried debugging through bugtrap, but strangely enough this crashes with the same error code (0xC0000005). I tried to open the kdmp file with visual studio, but i can't seem to make any sense out of this because it only shows me disassembler code when i step into the error (unless i have the right .pbb files, which i don't). Same goes for WinDbg. To make a long story short: I frankly don't have a single clue where to look for this error, and I'm hoping some bright soul on stackoverflow does. I'm happy to provide some code but at this moment I don't know which piece to provide.. Any help is greatly appreciated!

  • html5 vs flash - full comparison chart anywhere?

    - by iddqd
    So since Steve Jobs said Flash sucks and implied that HTML5 can do everything Flash can without the need for a Plugin, I keep hearing those exact words from a lot of People. I would really like to have a Chart somewhere (similar to http://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28HTML5%29#Form_elements_and_attributes ) that I can just show to those people. Showing all the little things that Flash can do right now, that HTML5/Ajax/CSS is not yet even thinking about. But of course also the things that HTML5 does better. I would like to see details compared like audio playback, realtime audio processing, byte level access, bitmap data manipulation, webcam access, binary sockets, stuff in the works such as P2P technology (adobe stratus) and all the stuff I don't know about myself. Ideally with examples of what can be accomplished with, lets say Binary Sockets (such as a POP3 client) because otherwise it won't mean a lot to non-programmers since they will just say "well we can do without Binary Sockets". And ideally with some current benchmarks and some examples of websites that use this technology. I've searched the web and am surprised not to find anything. So is there such a comparison somewhere? Or does anybody want to create this and post it to Wikipedia? ;-)

  • Java Sound API: Capturing sound output from a Target Port

    - by Kyle Kampy
    I'm writing a simple piece of software that streams audio over LAN. I have all of the network parts implemented, but what I'm stumbling on is using the Java Sound API. I have successfully captured audio from the microphone, and line-in, but I can't seem to capture from any target ports, like the speakers. My question is, is it possible to capture from the Master target port? Here is the piece of code that works on initializing the line. private boolean startCapture(){ try{ DataLine.Info info = new DataLine.Info( TargetDataLine.class, format); line = (TargetDataLine)AudioSystem.getLine(info); audioBuffer = new byte[bufferSize]; line.open(format); line.start(); return true; }catch(Exception e){ System.out.println("Exception thrown when capturing audio:\n" + e); return false; } } Running the code like this will just use the microphone as my line. Here is info about my sound system. Most important is probably the fact that I'm running Linux. Thanks in advance for any and all help you can give me.

  • Generate exe in .Net

    - by rwallace
    In .Net, you can generate byte code in memory, and presumably save the resulting program to a .exe file. To do the first step, I have the following test code adapted from http://www.code-magazine.com/Article.aspx?quickid=0301051 var name = new AssemblyName(); name.Name = "MyAssembly"; var ad = Thread.GetDomain(); var ab = ad.DefineDynamicAssembly(name, AssemblyBuilderAccess.Run); var mb = ab.DefineDynamicModule("MyModule"); var theClass = mb.DefineType("MathOps", TypeAttributes.Public); var retType = typeof(System.Int32); var parms = new Type[2]; parms[0] = typeof(System.Int32); parms[1] = typeof(System.Int32); var meb = theClass.DefineMethod("ReturnSum", MethodAttributes.Public, retType, parms); var gen = meb.GetILGenerator(); gen.Emit(OpCodes.Ldarg_1); gen.Emit(OpCodes.Ldarg_2); gen.Emit(OpCodes.Add_Ovf); gen.Emit(OpCodes.Stloc_0); gen.Emit(OpCodes.Br_S); gen.Emit(OpCodes.Ldloc_0); gen.Emit(OpCodes.Ret); theClass.CreateType(); How do you do the second step, and save the result to a .exe?

  • Paypal sandbox account in dotnet: "IPN Response invalid"

I downloaded the code below from Paypal: string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr"; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox); //Set values for the request back req.Method = "POST"; req.ContentType = "application/x-www-form-urlencoded"; byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength); string strRequest = Encoding.ASCII.GetString(param); strRequest += "&cmd=_notify-validate"; req.ContentLength = strRequest.Length; //for proxy //WebProxy proxy = new WebProxy(new Uri("http://url:port#")); //req.Proxy = proxy; //Send the request to PayPal and get the response StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII); streamOut.Write(strRequest); streamOut.Close(); StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream()); string strResponse = streamIn.ReadToEnd(); streamIn.Close(); if (strResponse == "VERIFIED") { //check the payment_status is Completed //check that txn_id has not been previously processed //check that receiver_email is your Primary PayPal email //check that payment_amount/payment_currency are correct //process payment } else if (strResponse == "INVALID") { //log for manual investigation } else { //log response/ipn data for manual investigation } When I add this snippet in my pageload event of my success page, I show the IPN response as INVALID, but amount is paid successfully. Why is this? Paypal's docs are not clear.

  • I/O between AIR client using Native process and executable java .jar

    - by aseem behl
    I am using Adobe AIR 2.0 native process API to launch a java executable jar. I/O is handled by writing to the input stream of the java process and reading from the output stream. The application is event based where several events are fired from the server. We catch these events in java code, handle them and write the output to the outputstream using the synchronized static method below. public class ReaderWriter { static Logger logger = Logger.getLogger(ReaderWriter.class); public synchronized static void writeToAir(String output){ try{ byte[] byteArray = output.getBytes(); DataOutputStream dataOutputStream = new DataOutputStream(System.out); dataOutputStream.write(byteArray); dataOutputStream.flush(); } catch (IOException e) { logger.info("Exception while writing the output. " + e); } } } The issue is that some messages are lost between the transfer and not all messages reach the AIR client. If I run the java application from the console I am receiving all the messages. It would be great if somebody could point out what I am missing. Following are some of the listeners used to send the event data to the AIR client. // class used to process Shutdown events from the Session private class SessionShutdownListener implements SessionListener{ public void onEvent(Event e) { Session.Shutdown sd = (Session.Shutdown) e; Session.ShutdownReason sr = sd.getReason(); String eventOutput = "eo;" + "Session Shutdown event ocurred reason=" + sr.strValue() + "\n"; ReaderWriter.writeToAir(eventOutput); } } // class used to process OperationSucceeded events from the Session private class SessionOperationSucceededListener implements SessionListener{ public void onEvent(Event e) { Session.OperationSucceeded os = (Session.OperationSucceeded) e; String eventOutput = "eo;" + "Session OperationSucceeded event ocurred" + "\n"; ReaderWriter.writeToAir(eventOutput); } }

  • Android, FragmentActivity and prevent Swipe

    - by FIG-GHD742
    I use android.support.v4.app.FragmentActivity for create a app with multi fragment/panels that can be access by drag/swipe between different part of the app. In one of my fragment I has a zoomable view and my problem is in case I is on the zoomable view I will prevent the use for drag/swipe to a other fragment. I has try to hack into android.support.v4.view.ViewPager for get the action from on Touch event but not work. I has try all of this case but not work: (All code is a a part of subclass to android.support.v4.view.ViewPager) Case 1: // Not working @Override protected void onPageScrolled(int position, float offset, int offsetPixels) { if (isPreventDrag()) { super.onPageScrolled(position, 1, 0); } else { super.onPageScrolled(position, offset, offsetPixels); } } Case 2: // Work but stop all event include the event to the target image view. @Override public boolean onInterceptTouchEvent(MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_DOWN: lastX = ev.getX(); // float lockScroll = false; return super.onInterceptTouchEvent(ev); case MotionEvent.ACTION_MOVE: this.lockScroll = this.isPreventDrag(); break; } if (lockScroll) { ev.setLocation(lastX, ev.getY()); return super.onInterceptTouchEvent(ev); } else { return super.onInterceptTouchEvent(ev); } } Case 3: // Work good, but by some unknown error I can drag the screen // some pixels before this stop the event. @Override public boolean onTouchEvent(MotionEvent ev) { if (this.isPreventDrag()) { return true; } else { return super.onTouchEvent(ev); } } I want a easy way to deactivate stop or deactivate if the use is allow to switch to a other Fragment. Here is a working code for me, I don't know what error I do before. // This work for me, @Override public boolean onInterceptTouchEvent(MotionEvent ev) { if (this.isPreventDrag()) { return false; } else { return super.onInterceptTouchEvent(ev); } }

  • HP QTP 10: Web-app testing - SomeObj.FireEvent("OnCLick") works, SomeObj.Object.FireEvent("OnCLick") doesn't

    - by Vitaliy
    Hi all! I have rich web app btuil with ExtJS. It has multi-select list control (created with JS+CSS). I want to click on some item in that list using HP QuickTest Pro 10 with Internet Explorer 6. I added that item into Object repository and found that following code works - selects some item: Browser("blah").Page("blah").WebElement("SomeElem").Click next code also works: Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseDown") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseUp") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onClick") But I want to select several items using shift+click method. I don't know to do that :( So I have a few questions: How can perform click with mouse on several web elements with Shift key pressed? I tried to do that using CreateEventObject + shiftKey set to true, but the method (perform fireEvent on DOM object, not object from Object repository) doesn't work: Browser("blah").Page("blah").WebElement("SomeElem").Object.FireEvent("onClick") What the difference between WebElement("Element").FireEvent("OnClick") and WebElement("Element").Object.FireEvent("OnClick") ? Plsease, help someone, because I fought with that problem a lot, but had no result. Thanks!

  • Re-using aggregate level formulas in SQL - any good tactics?

    - by Cade Roux
    Imagine this case, but with a lot more component buckets and a lot more intermediates and outputs. Many of the intermediates are calculated at the detail level, but a few things are calculated at the aggregate level: DECLARE @Profitability AS TABLE ( Cust INT NOT NULL ,Category VARCHAR(10) NOT NULL ,Income DECIMAL(10, 2) NOT NULL ,Expense DECIMAL(10, 2) NOT NULL ) ; INSERT INTO @Profitability VALUES ( 1, 'Software', 100, 50 ) ; INSERT INTO @Profitability VALUES ( 2, 'Software', 100, 20 ) ; INSERT INTO @Profitability VALUES ( 3, 'Software', 100, 60 ) ; INSERT INTO @Profitability VALUES ( 4, 'Software', 500, 400 ) ; INSERT INTO @Profitability VALUES ( 5, 'Hardware', 1000, 550 ) ; INSERT INTO @Profitability VALUES ( 6, 'Hardware', 1000, 250 ) ; INSERT INTO @Profitability VALUES ( 7, 'Hardware', 1000, 700 ) ; INSERT INTO @Profitability VALUES ( 8, 'Hardware', 5000, 4500 ) ; SELECT Cust ,Profit = SUM(Income - Expense) ,Margin = SUM(Income - Expense) / SUM(Income) FROM @Profitability GROUP BY Cust SELECT Category ,Profit = SUM(Income - Expense) ,Margin = SUM(Income - Expense) / SUM(Income) FROM @Profitability GROUP BY Category SELECT Profit = SUM(Income - Expense) ,Margin = SUM(Income - Expense) / SUM(Income) FROM @Profitability Notice how the same formulae have to be used at the different aggregation levels. This results in code duplication. I have thought of using UDFs (either scalar or table valued with an OUTER APPLY, since many of the final results may share intermediates which have to be calculated at the aggregate level), but in my experience the scalar and multi-statement table-valued UDFs perform very poorly. Also thought about using more dynamic SQL and applying the formulas by name, basically. Any other tricks, techniques or tactics to keeping these kinds of formulae which need to be applied at different levels in sync and/or organized?

  • RDP through TCP Proxy

    - by johng100
    Hi, First time in Stackoverflow and I'm hoping someone can help me. I'm looking at a proof of concept to pass RDP traffic through a TCP Proxy/tunnel which will pass through firewalls using HTTPS. The problem has to do with deploying images to machines and so it can't be assumed that the .NET framework will be present, so C++ is being used at the deployment end of a connection. The basic system I have at present is a program which listens for client connections on a port then passes any data to a WCF service which stores it as a byte array. A deployment machine (using GSoap and C++) polls the WCF service for messages and if it finds them then passes the data onto the target server process via sockets. I know this sounds horrible, but it works for simple test clients and server passing data to and from simple test client and server programs via this WCF/C++/C# proxy layer. But I have to support traffic from RDP, VNC and possibly others, so I need a transparent proxy to do this and am wondering whether the above approach is worth pursuing. I've read up on SSH tunneling and that seems a possibility. My basic question is is it possible to tunnel RDP traffic over HTTPS using custom code. Thanks John

  • Retrieving many huge sized EPS files and converting them to JPEG in ASP.NET application

    - by Ashish Gupta
    I have many (600) EPS files(300 KB - 1 MB) in database. In my ASP.NET application (using ASP.NET 4.0) I need to retrieve them one by one and call a web service which would convert the content to the JPEG file and update the database (JPEGContent column with the JPEG content). However, retrieving the content for 600 of them itself takes too long from the SQL management studio itself (takes 5 minutes for 10 EPS contents). So I have two issues:- 1) How to get the EPS content ( unfortunately, selecting certain number of content is not an option :-( ):- Approach 1:- foreach(var DataRow in DataTable.Rows) { // get the Id and byte[] of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or foreach(var DataRow in DataTable.Rows) { // get only the Id of EPS // Hit database to get the content of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or Any other approach? 2) Converting EPS to JPEG using a web method for 600 contents. Ofcourse, each call would be a long running operation. Would task parellel library (TPL) be a better way to achieve this? Also, is doing the entire thing in a SQL CLR function a good idea?

  • [ActionScript 3] Array subclasses cannot be deserialized, Error #1034

    - by aaaidan
    I've just found a strange error when deserializing from a ByteArray, where Vectors cannot contain types that extend Array: there is a TypeError when they are deserialized. TypeError: Error #1034: Type Coercion failed: cannot convert []@4b8c42e1 to com.myapp.ArraySubclass. at flash.utils::ByteArray/readObject() at com.myapp::MyApplication()[/Users/aaaidan/MyApp/com/myapp/MyApplication.as:99] Here's how: public class Application extends Sprite { public function Application() { // register the custom class registerClassAlias("MyArraySubclass", MyArraySubclass); // write a vector containing an array subclass to a byte array var vec:Vector.<MyArraySubclass> = new Vector.<MyArraySubclass>(); var arraySubclass:MyArraySubclass = new MyArraySubclass(); arraySubclass.customProperty = "foo"; vec.push(arraySubclass); var ba:ByteArray = new ByteArray(); ba.writeObject(arraySubclass); ba.position = 0; // read it back var arraySubclass2:MyArraySubclass = ba.readObject() as MyArraySubclass; // throws TypeError } } public class MyArraySubclass extends Array { public var customProperty:String = "default"; } It's a pretty specific case, but it seems very odd to me. Anyone have any ideas what's causing it, or how it could be fixed?
