  • handling DATETIME values 0000-00-00 00:00:00 in JDBC

    - by Jason S
    I get an exception (see below) if I try to do resultset.getString("add_date"); for a JDBC connection to a MySQL database containing a DATETIME value of 0000-00-00 00:00:00 (the quasi-null value for DATETIME), even though I'm just trying to get the value as string, not as an object. I got around this by doing SELECT CAST(add_date AS CHAR) as add_date which works, but seems silly... is there a better way to do this? My point is that I just want the raw DATETIME string, so I can parse it myself as is. note: here's where the 0000 comes in: (from http://dev.mysql.com/doc/refman/5.0/en/datetime.html) Illegal DATETIME, DATE, or TIMESTAMP values are converted to the “zero” value of the appropriate type ('0000-00-00 00:00:00' or '0000-00-00'). The specific exception is this one: SQLException: Cannot convert value '0000-00-00 00:00:00' from column 5 to TIMESTAMP. SQLState: S1009 VendorError: 0 java.sql.SQLException: Cannot convert value '0000-00-00 00:00:00' from column 5 to TIMESTAMP. at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1055) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:956) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:926) at com.mysql.jdbc.ResultSetImpl.getTimestampFromString(ResultSetImpl.java:6343) at com.mysql.jdbc.ResultSetImpl.getStringInternal(ResultSetImpl.java:5670) at com.mysql.jdbc.ResultSetImpl.getString(ResultSetImpl.java:5491) at com.mysql.jdbc.ResultSetImpl.getString(ResultSetImpl.java:5531)

  • How to integrate a Ipython console in a PyQT application

    - by user1800689
    I am developing PyQt software for my lab. In this software, I am loading different kind of RAW and analyzed data from a mySQL database (usually in arrays). I would like to integrate an Iython console in a Widget, so that I could interact easily with these data. I had some difficulties with Ipython 0.13 to do this. Here is what I already have (The whole code is very long, so I just show the part containing the widget, the Ipython console and the corresponding import line, if you need more, just tell me): ##I load everything useful to my application, including the following line from IPython.frontend.qt.console.qtconsoleapp import IPythonQtConsoleApp ##then is my whole software ##here is a class containing the Graphical User Interface elements. A button call the following function. self.Shell_Widget is the widget containing the Ipython console, self.MainWindow is the application mainwindow def EmbeddedIpython(self): """ This function should launch an Ipython console """ self.Shell_Widget = QtGui.QDockWidget(self.MainWindow) #Widget creation self.MainWindow.addDockWidget(4,self.Shell_Widget) self.Shell_Widget.setMinimumSize(400,420) console = IPythonQtConsoleApp() #Console Creation console.initialize() console.start() self.Shell_Widget.show() So, as wanted, an Ipython console is launched, and seems to work, but I can not access the whole application variables ,arrays etc... I think the Ipython console is launched independently from my software, but here is my limit in programming... Does someone know how to launch Ipython within my application? Maybe a missing parameter, or a different way to integrate Ipython. for information, this doesn't work: Embedding IPython Qt console in a PyQt application Thank you for your help!!

  • Possible to Inspect Innards of Core C# Functionality

    - by Nick Babcock
    I was struck today, with the inclination to compare the innards of Buffer.BlockCopy and Array.CopyTo. I am curious to see if Array.CopyTo called Buffer.BlockCopy behind the scenes. There is no practical purpose behind this, I just want to further my understanding of the C# language and how it is implemented. Don't jump the gun and accuse me of micro-optimization, but you can accuse me of being curious! When I ran ILasm on mscorlib.dll I received this for Array.CopyTo .method public hidebysig newslot virtual final instance void CopyTo(class System.Array 'array', int32 index) cil managed { // Code size 0 (0x0) } // end of method Array::CopyTo and this for Buffer.BlockCopy .method public hidebysig static void BlockCopy(class System.Array src, int32 srcOffset, class System.Array dst, int32 dstOffset, int32 count) cil managed internalcall { .custom instance void System.Security.SecuritySafeCriticalAttribute::.ctor() = ( 01 00 00 00 ) } // end of method Buffer::BlockCopy Which, frankly, baffles me. I've never run ILasm on a dll/exe I didn't create. Does this mean that I won't be able to see how these functions are implemented? Searching around only revealed a stackoverflow question, which Marc Gravell said [Buffer.BlockCopy] is basically a wrapper over a raw mem-copy While insightful, it doesn't answer my question if Array.CopyTo calls Buffer.BlockCopy. I'm specifically interested in if I'm able to see how these two functions are implemented, and if I had future questions about the internals of C#, if it is possible for me to investigate it. Or am I out of luck?

  • What's the fastest way to bulk insert a lot of data in SQL Server (C# client)

    - by Andrew
    I am hitting some performance bottlenecks with my C# client inserting bulk data into a SQL Server 2005 database and I'm looking for ways in which to speed up the process. I am already using the SqlClient.SqlBulkCopy (which is based on TDS) to speed up the data transfer across the wire which helped a lot, but I'm still looking for more. I have a simple table that looks like this: CREATE TABLE [BulkData]( [ContainerId] [int] NOT NULL, [BinId] [smallint] NOT NULL, [Sequence] [smallint] NOT NULL, [ItemId] [int] NOT NULL, [Left] [smallint] NOT NULL, [Top] [smallint] NOT NULL, [Right] [smallint] NOT NULL, [Bottom] [smallint] NOT NULL, CONSTRAINT [PKBulkData] PRIMARY KEY CLUSTERED ( [ContainerIdId] ASC, [BinId] ASC, [Sequence] ASC )) I'm inserting data in chunks that average about 300 rows where ContainerId and BinId are constant in each chunk and the Sequence value is 0-n and the values are pre-sorted based on the primary key. The %Disk time performance counter spends a lot of time at 100% so it is clear that disk IO is the main issue but the speeds I'm getting are several orders of magnitude below a raw file copy. Does it help any if I: Drop the Primary key while I am doing the inserting and recreate it later Do inserts into a temporary table with the same schema and periodically transfer them into the main table to keep the size of the table where insertions are happening small Anything else? -- Based on the responses I have gotten, let me clarify a little bit: Portman: I'm using a clustered index because when the data is all imported I will need to access data sequentially in that order. I don't particularly need the index to be there while importing the data. Is there any advantage to having a nonclustered PK index while doing the inserts as opposed to dropping the constraint entirely for import? Chopeen: The data is being generated remotely on many other machines (my SQL server can only handle about 10 currently, but I would love to be able to add more). It's not practical to run the entire process on the local machine because it would then have to process 50 times as much input data to generate the output. Jason: I am not doing any concurrent queries against the table during the import process, I will try dropping the primary key and see if that helps. ~ Andrew

  • Retactoring advanced has_many example

    - by atmorell
    Hello, My user model has three relations for the same message model, and is using raw SQL :/ Is there a better more rails way to achieve the same result? Could the foreign key be changed dynamically? e.g User.messages.sent (foreign key = author_id) and User.messages.received (foreign key = recipient ) I have been trying to move some of the logic into scopes in the message model, but the user.id is not available from the message model... Any thoughts? Table layout: create_table "messages", :force => true do |t| t.string "subject" t.text "body" t.datetime "created_at" t.datetime "updated_at" t.integer "author_id" t.integer "recipient_id" t.boolean "author_deleted", :default => false t.boolean "recipient_deleted", :default => false end This is my relations for my user model: has_many :messages_received, :foreign_key => "recipient_id", :class_name => "Message", :conditions => ['recipient_deleted = ?', false] has_many :messages_sent, :foreign_key => "author_id", :class_name => "Message", :conditions => ['author_deleted = ?', false] has_many :messages_deleted, :class_name => "Message", :finder_sql => 'SELECT * FROM Messages WHERE author_id = #{self.id} AND author_deleted = true OR recipient_id = #{self.id} AND recipient_deleted = true' Best regards.

  • Application lifecycle and onCreate method in the the android sdk

    - by Leif Andersen
    I slapped together a simple test application that has a button, and makes a noise when the user clicks on it. Here are it's method: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button b = (Button)findViewById(R.id.easy); b.setOnClickListener(this); } public void onClick(View v) { MediaPlayer mp = MediaPlayer.create(this, R.raw.easy); mp.start(); while(true) { if (!mp.isPlaying()) { mp.release(); break; } } } My question is, why is onCreate acting like it's in a while loop? I can click on the button whenever, and it makes the sound. I might think it was just a property of listeners, but the Button object wasn't a member variable. I thought that Android would just go through onCreate onse, and proceed onto the next lifecycle method. Also, I know that my current way of seeing if the sound is playing is crap...I'll get to that later. :) Thank you.

  • Python minidom and UTF-8 encoded XML with hash references

    - by Jakob Simon-Gaarde
    Hi I am experiencing some difficulty in my home project where I need to parse a SOAP request. The SOAP is generated with gSOAP and involves string parameters with special characters like the danish letters "æøå". gSOAP builds SOAP requests with UTF-8 encoding by default, but instead of sending the special chatacters in raw format (ie. bytes C3A6 for the special character "æ") it sends what I think is called character hash references (ie. &#195;&#166;). I don't completely understand why gSOAP does it this way as I can see that it has marked the incomming payload as being UTF-8 encoded anyway (Content-Type: text/xml; charset=utf-8), but this is besides the question (I think). Anyway I guess gSOAP probably is obeying transport rules, or what? When I parse the request from gSOAP in python with xml.dom.minidom.parseString() I get element values as unicode objects which is fine, but the character hash references are not decoded as UTF-8 character codes. It unescapes the character hash references, but does not decode the string afterwards. In the end I have a unicode string object with UTF-8 encoding: So if the string "æble" is contained in the XML, it comes like this in the request: "&#195;&#166;ble" After parsing the XML the unicode string in the DOM Text Node's data member looks like this: u'\xc3\xa6ble' I would expect it to look like this: u'\xe6ble' What am I doing wrong? Should I unescape the SOAP XML before parsing it, or is it somewhere else I should be looking for the solution, maybe gSOAP? Thanks in advance. Best regards Jakob Simon-Gaarde

  • moving audio over a local network using GStreamer

    - by James Turner
    I need to move realtime audio between two Linux machines, which are both running custom software (of mine) which builds on top of Gstreamer. (The software already has other communication between the machines, over a separate TCP-based protocol - I mention this in case having reliable out-of-band data makes a difference to the solution). The audio input will be a microphone / line-in on the sending machine, and normal audio output as the sink on the destination; alsasrc and alsasink are the most likely, though for testing I have been using the audiotestsrc instead of a real microphone. GStreamer offers a multitude of ways to move data round over networks - RTP, RTSP, GDP payloading, UDP and TCP servers, clients and sockets, and so on. There's also many examples on the web of streaming both audio and video - but none of them seem to work for me, in practice; either the destination pipeline fails to negotiate caps, or I hear a single packet and then the pipeline stalls, or the destination pipeline bails out immediately with no data available. In all cases, I'm testing on the command-line just gst-launch. No compression of the audio data is required - raw audio, or trivial WAV, uLaw or aLaw encoding is fine; what's more important is low-ish latency.

  • QueryString malformed after URLDecode

    - by pdavis
    I'm trying to pass in a Base64 string into a C#.Net web application via the QueryString. When the string arrives the "+" (plus) sign is being replaced by a space. It appears that the automatic URLDecode process is doing this. I have no control over what is being passed via the QueryString. Is there any way to handle this server side? Example: http://localhost:3399/Base64.aspx?VLTrap=VkxUcmFwIHNldCB0byAiRkRTQT8+PE0iIHBsdXMgb3IgbWludXMgNSBwZXJjZW50Lg== Produces: VkxUcmFwIHNldCB0byAiRkRTQT8 PE0iIHBsdXMgb3IgbWludXMgNSBwZXJjZW50Lg== People have suggested URLEncoding the querystring: System.Web.HttpUtility.UrlEncode(yourString) I can't do that as I have no control over the calling routine (which is working fine with other languages). There was also the suggestion of replacing spaces with a plus sign: Request.QueryString["VLTrap"].Replace(" ", "+"); I had though of this but my concern with it, and I should have mentioned this to start, is that I don't know what other characters might be malformed in addition to the plus sign. My main goal is to intercept the QueryString before it is run through the decoder. To this end I tried looking at Request.QueryString.toString() but this contained the same malformed information. Is there any way to look at the raw QueryString before it is URLDecoded? After further testing it appears that .Net expects everything coming in from the QuerString to be URL encoded but the browser does not automatically URL encode GET requests.

  • Working with a CSV file with odd encapsulation // PHP

    - by Patrick
    I have a CSV file that I'm working with, and all the fields are comma separated. But some of the fields themselves, contain commas. In the raw CSV file, the fields that contain commas, are encapsulated with quotes, as seen here; "Doctor Such and Such, Medical Center","555 Scruff McGruff, Suite 103, Chicago IL 60652",(555) 555-5555,,,,something else the code I'm using is below <?PHP $file_handle = fopen("file.csv", "r"); $i=0; while (!feof($file_handle) ) { $line = fgetcsv($file_handle, 1024); $c=0; foreach($line AS $key=>$value){ if($i != 0){ if($c == 0){ echo "[ROW $i][COL $c] - $value"; //First field in row, show row # }else{ echo "[COL $c] - $value"; // Remaining fields in row } } $c++; } echo "<br>"; // Line Break to next line $i++; } fclose($file_handle); ?> The problem is I'm getting the fields with the commas split into two fields, which messes up the number of columns I'm supposed to have. Is there any way I could search for commas within quotes and convert them, or another way to deal with this?

  • Is it possible to read data that has been separately copied to the Android sd card without having ro

    - by icecream
    I am developing an application that needs to access data on the sd card. When I run on my development device (an odroid with Android 2.1) I have root access and can construct the path using: File sdcard = Environment.getExternalStorageDirectory(); String path = sdcard.getAbsolutePath() + File.separator + "mydata" File data = new File(path); File[] files = data.listFiles(new FilenameFilter() { @Override public boolean accept(File dir, String filename) { return filename.toLowerCase().endsWith(".xyz"); }}); However, when I install this on a phone (2.1) where I do not have root access I get files == null. I assume this is because I do not have the right permissions to read the data from the sd card. I also get files == null when just trying to list files on /sdcard. So the same applies without my constructed path. Also, this app is not intended to be distributed through the app store and is needs to use data copied separately to the sd card so this is a real use-case. It is too much data to put in res/raw (I have tried, it did not work). I have also tried adding: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> to the manifest, even though I only want to read the sd card, but it did not help. I have not found a permission type for reading the storage. There is probably a correct way to do this, but I haven't been able to find it. Any hints would be useful.

  • error handler isn't called when file is uploaded via ajax using jQuery form plugin

    - by scompt.com
    Here's my test case. If the form is posted, a 500 error response is sent. If not, the form is sent. If the file input tag is commented out, the error handler is called. If the file input tag is present, the error handler isn't called. I think this might have something to do with the fact that jQuery needs to use an iframe to handle the upload and iframes don't seem to respond to the error handler. Edit: If I add iframe: true to the options passed to ajaxSubmit to force the use of an iframe, the non-file-upload case stops working also, so it definitely has to do with the iframe. Edit2: I'm using the jQuery Form Plugin. <?php if($_SERVER['REQUEST_METHOD'] == 'POST') { header('HTTP/1.1 500 Internal Server Error'); die; } else {?> <html><head> <script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js?ver=2.9.2'></script> <script type='text/javascript' src='http://github.com/malsup/form/raw/master/jquery.form.js?v2.43'></script> <script type="text/javascript"> jQuery(document).ready(function() { jQuery('a').click(function() {jQuery('form').ajaxSubmit({error: function(){alert('error handler called');}})}); }); </script> </head><body> <form method="POST"> <input type="text" name="mytext" /> <input type="file" name="myfile" /><!-- comment this element out --> <input type="hidden" name="blah" value="blah" /> <a>submit</a> </form> </body></html> <?php } Is there any way to get the error handler to be called in both situations?

  • Scripts to parse and download iTunes Connect and AppStore data

    - by bradhouse
    I'm looking for recommendations of a script or series of scripts that download and parse iTunes Connect sales data and AppStore comments, ratings and rankings data for a defined app. I'm also aware of solutions like: AppViz appsales-mobile iphone-stats Heartbeat.app I'm sure I'll find a few more with more searching. I can't help but feel there must be a really decent set of open source scripts out there to do this, given how many developers are now writing apps for the AppStore. Would be interested to hear any commercial offerings as well (although my personal preference is for open source, so I can at least see what it is doing with my iTunes Connect login credentials). To be clear, I'm really looking for something that hits all of the areas mentioned: App Store (per store) Comments Ratings Category/store rankings iTunes Connect The contents of the sales reports Analysis/graphs of the data is not necessary (but would be a nice to have I guess). I'm not really looking for something like AppSales Mobile above, I would like the raw data so I can do my own analysis and formatting. So far it looks like AppViz (listed above) is the best out there. Any suggestions on what is good/available or should I just go roll my own?

  • Why Spark viewengine renders unnecessary (or unexpected) quotes?

    - by Arnis L.
    If i add pageBaseType="Spark.Web.Mvc.SparkView" in my web.config (necessary to fix intellisense), somehow it does not render links (probably not only) correctly anymore. This is how it's supposed to look like (and does, if page base type is not specified)= This is how it looks when base type is specified= Chrome source viewer shows identical page source code for both cases= <body> <div class="content"> <div class="navigation"> <a href="/Employee/List">Employees</a> <a href="/Product/List">Products</a> <a href="/Store/List">Stores</a> <div class="navigation_title"> Navigation</div> </div> <div class="main"> <div class="content"> <h2>Employees</h2>Nothing found... &lt;a href=&quot;/Employee/Create&quot;&gt;Create&lt;/a&gt; </div> </div> </div> </body> Developer tools does not= So - why my link gets htmlencoded (if that's what happens)? If it's default behavior, then how to render raw html? Using latest Spark version, rebuilt with Asp.Net Mvc2 RC assemblies.

  • String Comparison containing hyphens not matching

    - by Christo Fur
    I have a method in a url rewriting module that looks like this public bool Match(Uri url) { string x = url.PathAndQuery.ToLowerInvariant(); string y = RuleData.ToLowerInvariant(); return x.Contains(y); } However, it is not returning true for the following values: x = "/xx09-02-09xx"; y = "09-02-09"; but if I write a unit test with the raw strings, like below, it does return true [Test] public void Contains() { string x = "/xx09-02-09xx"; string y = "09-02-09"; Assert.IsTrue(x.Contains(y)); // this returns true } What could be the difference? The encoding? The culture? Have tried removing the ToLowerInvarient(), but that makes no difference have tried all the following in the Match method bool contains = x.Contains(y); bool contains1 = x.IndexOf(y) != -1; bool contains2 = x.IndexOf(y, StringComparison.OrdinalIgnoreCase) != -1; bool contains3 = x.IndexOf(y, StringComparison.InvariantCultureIgnoreCase) != -1; bool contains4 = x.IndexOf(y, StringComparison.CurrentCultureIgnoreCase) != -1; but none return true for those values, when run in the rewrite module. But they do in the unit test. So something about the strings is clearly different any ideas?

  • Why can't perfmon see instances of my custom performance counter?

    - by spoulson
    I'm creating some custom performance counters for an application. I wrote a simple C# tool to create the categories and counters. For example, the code snippet below is basically what I'm running. Then, I run a separate app that endlessly refreshes the raw value of the counter. While that runs, the counter and dummy instance are seen locally in perfmon. The problem I'm having is that the monitoring system we use can't see the instances in the multi-instance counter I've created when viewing remotely from another server. When using perfmon to browse the counters, I can see the category and counters, but the instances box is grayed out and I can't even select "All instances", nor can I click "Add". Using other access methods, like [typeperf][1] exhibit similar issues. I'm not sure if this is a server or code issue. This is only reproducible in the production environment where I need it. On my desktop and development servers, it works great. I'm a local admin on all servers. CounterCreationDataCollection collection = new CounterCreationDataCollection(); var category_name = "My Application"; var counter_name = "My counter name"; CounterCreationData ccd = new CounterCreationData(); ccd.CounterType = PerformanceCounterType.RateOfCountsPerSecond64; ccd.CounterName = counter_name; ccd.CounterHelp = counter_name; collection.Add(ccd); PerformanceCounterCategory.Create(category_name, category_name, PerformanceCounterCategoryType.MultiInstance, collection); Then, in a separate app, I run this to generate dummy instance data: var pc = new PerformanceCounter(category_name, counter_name, instance_name, false); while (true) { pc.RawValue = 0; Thread.Sleep(1000); }

  • Rendering LaTeX on third-party websites?

    - by A. Rex
    There are some sites on the web that render LaTeX into some more readable form, such as Wikipedia, some Wordpress blogs, and MathOverflow. They may use images, MathML, jsMath, or something like that. There are other sites on the web where LaTeX appears inline and is not rendered, such as the arXiv, various math forums, or my email. In fact, it is quite common to see an arXiv paper's abstract with raw LaTeX in it, e.g. this paper. Is there a plugin available for Firefox, or would it be possible to write one, that renders LaTeX within pages that do not provide a rendering mechanism themselves? (The LaTeX would be enclosed within dollar signs, e.g. $\pi$. See the arXiv link above.) Some notes: It may be impossible to render some of the code, because authors often copy-paste code directly from their source TeX files, which may contain things like "\cite{foo}" or undefined commands. These should be left alone. This question is a repost of a question from MathOverflow that was closed for not being related to math. There is one answer there, which is helpful, but perhaps Stack Overflow can provide better answers. I program a lot, but Javascript is not my specialty, so comments along the lines of "look at this library" are not particularly helpful to me (but may be to others).

  • Is there a library that can decompile a method into an Expression tree, with support for CLR 4.0?

    - by Daniel Earwicker
    Previous questions have asked if it is possible to turn compiled delegates into expression trees, for example: http://stackoverflow.com/questions/767733/converting-a-net-funct-to-a-net-expressionfunct The sane answers at the time were: It's possible, but very hard and there's no standard library solution. Use Reflector! But fortunately there are some greatly-insane/insanely-great people out there who like reverse engineering things, and they make difficult things easy for the rest of us. Clearly it is possible to decompile IL to C#, as Reflector does it, and so you could in principle instead target CLR 4.0 expression trees with support for all statement types. This is interesting because it wouldn't matter if the compiler's built-in special support for Expression<> lambdas is never extended to support building statement expression trees in the compiler. A library solution could fill the gap. We would then have a high-level starting point for writing aspect-like manipulations of code without having to mess with raw IL. As noted in the answers to the above linked question, there are some promising signs but I haven't succeeded in finding if there's been much progress since by searching. So has anyone finished this job, or got very far with it? Note: CLR 4.0 is now released. Time for another look-see.

  • Simply if Statement for checking co-ordinate square.

    - by JonB
    I have an UIImageView and taking the raw touch input. I need to check if a touch is within a certain set of squares. At the moment... I have this if statement.... if(46 < touchedAt.x && touchedAt.x < 124 && 18 < touchedAt.y && touchedAt.y < 75) but I have tried to simplify it to this one... if(46 < touchedAt.x < 124 && 18 < touchedAt.y < 75) It didn't work. Is it possible to simplify like this or am I stuck with the slightly lengthier version at the top? Is there a reason why the types of comparisons in the bottom if don't work? Many Thanks.

  • Android always play intro clip

    - by mrmamon
    I'm trying to make my app to play intro clip for only when I start activities. But from my code it's always play the clip after wakeup before resume to app although I did not closed the app. What can I do to fix this prob? Thanks From main: startActivity(new Intent(this, MyIntro.class)); From MyIntro: public class MyIntro extends Activity implements OnCompletionListener { int a; @Override protected void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.intro); playIntro(); } public void onConfigurationChanged(Configuration newConfig) { setContentView(R.layout.intro); } public void onCompletion(MediaPlayer arg0) { // TODO Auto-generated method stub this.finish(); } private void playIntro(){ setContentView(R.layout.intro); VideoView video = (VideoView) this.findViewById(R.id.VideoView01); Uri uri = Uri.parse("android.resource://real.app/" + R.raw.intro); video.setVideoURI(uri); video.requestFocus(); video.setOnCompletionListener(this); video.start(); } }

  • Loading machinecode from file into memory and executing in C -- mprotect failing

    - by chartreusekitsune
    Hi I'm trying to load raw machine code into memory and run it from within a C program, right now when the program executes it breaks when trying to run mprotect on the memory to make it executable. I'm also not entirely sure that if the memory does get set right it will execute. What I currently have is the following: #include <memory.h> #include <sys/mman.h> #include <stdio.h> int main ( int argc, char **argv ) { FILE *fp; int sz = 0; char *membuf; int output = 0; fp = fopen(argv[1],"rb"); if(fp == NULL) { printf("Failed to open file, aborting!\n"); exit(1); } fseek(fp, 0L, SEEK_END); sz = ftell(fp); fseek(fp, 0L, SEEK_SET); membuf = (char *)malloc(sz*sizeof(char)); if(membuf == NULL) { printf("Failed to allocate memory, aborting!\n"); exit(1); } memset(membuf, 0x90, sz*sizeof(char)); if( mprotect(membuf, sz*sizeof(char), PROT_EXEC | PROT_READ | PROT_WRITE) == -1) { printf("mprotect failed!!! aborting!\n"); exit(1); } if((sz*sizeof(char)) != fread(membuf, sz*sizeof(char), 1, fp)) { printf("Read failed, aborting!\n"); exit(1); } __asm__ ( "call %%eax;" : "=a" (output) : "a" (membuf) ); printf("Output = %x\n", output); return 0; }
