  • Information about PTE's (Page Table Entries) in Windows

    - by Patrick
    In order to find more easily buffer overflows I am changing our custom memory allocator so that it allocates a full 4KB page instead of only the wanted number of bytes. Then I change the page protection and size so that if the caller writes before or after its allocated piece of memory, the application immediately crashes. Problem is that although I have enough memory, the application never starts up completely because it runs out of memory. This has two causes: since every allocation needs 4 KB, we probably reach the 2 GB limit very soon. This problem could be solved if I would make a 64-bit executable (didn't try it yet). even when I only need a few hundreds of megabytes, the allocations fail at a certain moment. The second problem is the biggest one, and I think it's related to the maximum number of PTE's (page table entries, which store information on how Virtual Memory is mapped to physical memory, and whether pages should be read-only or not) you can have in a process. My questions (or a cry-for-tips): Where can I find information about the maximum number of PTE's in a process? Is this different (higher) for 64-bit systems/applications or not? Can the number of PTE's be configured in the application or in Windows? Thanks, Patrick PS. note for those who will try to argument that you shouldn't write your own memory manager: My application is rather specific so I really want full control over memory management (can't give any more details) Last week we had a memory overwrite which we couldn't find using the standard C++ allocator and the debugging functionality of the C/C++ run time (it only said "block corrupt" minutes after the actual corruption") We also tried standard Windows utilities (like GFLAGS, ...) but they slowed down the application by a factor of 100, and couldn't find the exact position of the overwrite either We also tried the "Full Page Heap" functionality of Application Verifier, but then the application doesn't start up either (probably also running out of PTE's)

  • Insert a doctype into an XML document (Java/ SAX)

    - by Thom Nichols
    Imagine you have an XML document and imagine you have the DTD but the document itself doesn't actually specify a DOCTYPE ... How would you insert the DOCTYPE declaration, preferably by specifying it on the parser (similar to how you can set the schema for a document that will be parsed) or by inserting the necessary SAX events via an XMLFilter or the like? I've found many references to EntityResolver, but that is what's invoked once a DOCTYPE is found during parsing and it's used to point to a local DTD file. EntityResolver2 appears to have what I'm looking for but I haven't found any examples of usage. This is the closest I've come thus far: (code is Groovy, but close enough that you should be able to understand it...) import org.xml.sax.* import org.xml.sax.ext.* import org.xml.sax.helpers.* class XmlFilter extends XMLFilterImpl { public XmlFilter( XMLReader reader ) { super(reader) } @Override public void startDocument() { super.startDocument() super.resolveEntity( null, 'file:///./entity.dtd') println "filter startDocument" } } class MyHandler extends DefaultHandler2 { public InputSource resolveEntity(String name, String publicId, String baseURI, String systemId) { println "entity: $name, $publicId, $baseURI, $systemId" return new InputSource(new StringReader('<!ENTITY asdf "&#161;">')) } } def handler = new MyHandler() def parser = XMLReaderFactory.createXMLReader() parser.setFeature 'http://xml.org/sax/features/use-entity-resolver2', true def filter = new XmlFilter( parser ) filter.setContentHandler( handler ) filter.setEntityResolver( handler ) filter.parse( new InputSource(new StringReader('''<?xml version="1.0" ?> <test>one &asdf; two! &nbsp; &iexcl;&pound;&cent;</test>''')) ); I see resolveEntity called but still hit org.xml.sax.SAXParseException: The entity "asdf" was referenced, but not declared. at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1231) at org.xml.sax.helpers.XMLFilterImpl.parse(XMLFilterImpl.java:333) I guess this is because there's no way to add SAX events that the parser knows about, I can only add events via a filter that's upstream from the parser which are passed along to the ContentHandler. So the document has to be valid going into the XMLReader. Any way around this? I know I can modify the raw stream to add a doctype or possibly do a transform to set a DTD... Any other options?

  • Copying Excel Worksheets in POI

    - by Patrick Nichols
    Does anyone know of a means to copy a worksheet from one workbook to another using POI? The Workbook class has a cloneSheet method, but there doesn't seem to be able to insert a cloned sheet into a new workbook? If there isn't an API to do this easily, does anyone have the code to copy all of the data (styles, column widths, data, etc) from one sheet to another? The jxls has methods to copy sheets, but they don't work when copying between workbooks.

  • Simple number-to-number (or number-to-hex) encryption algorithm that minimizes # of characters

    - by Clay Nichols
    I need to encrypt a number and I and this encrypted value will be given to a customer ask a key so I want to minimize the number of digits and make them all printable. So I'd like the result to be either all number or all Hex characters. The current encryption method I'm using (for non numbers) converts the characters to hex (2 hex digits each). That doubles the number of characters. I also considered just treating the input as hex (so each pair of numbers is treated as a Hex pair, but then you have ambiguity between an input of 0123 and 123 (when decrypting that leading '0' is lost. Any suggestions?

  • paypal IPN sends two different twice

    - by Patrick
    I've come across something a bit strange I was hoping someone with more experience with Paypal can explain, Specifically the IPN feature. It seems I'm getting two very different hits to my IPN listener. The first one always fails, The second one passes. Now I know Paypal tends to send duplicates, But what I've noticed is two very different $_POST arrays being recieved. Here's the respones : [2014-06-08 23:51:19] RAW POST DATA : Array ( [transaction] => Array ( [0] => ILS 20.00 ) [payment_request_date] => Sun Jun 08 13:52:12 PDT 2014 [return_url] => MY_URL [fees_payer] => EACHRECEIVER [ipn_notification_url] => MY_URL [sender_email] => patrick[email protected] //fake email [verify_sign] => ANp5TpLat3.2ylx.cECtVZ..5HejAsVcs05tdVC7RldmeYNJ91SKaqFJ [test_ipn] => 1 [cancel_url] => MY_URL [pay_key] => AP-04B74091M7083584A [action_type] => PAY [transaction_type] => Adaptive Payment PAY [tracking_id] => 13 // This is a number I passed, But it doesn't exist in the 2nd POST [status] => COMPLETED [log_default_shipping_address_in_transaction] => false [charset] => windows-1252 [notify_version] => UNVERSIONED [reverse_all_parallel_payments_on_error] => false ) [2014-06-08 23:51:19] RAW POST DATA : Array ( [transaction_subject] => [payment_date] => 13:52:28 Jun 08, 2014 PDT [txn_type] => web_accept [last_name] => test [residence_country] => US [item_name] => .... (this continues for quite a bit more) .... [payment_fee] => [mc_fee] => 1.78 [mc_gross] => 20.00 [custom] => [charset] => windows-1252 [notify_version] => 3.8 [ipn_track_id] => f93ce8bdd4382 ) My problem The first IPN with the juicy tracking_id fails, the 2nd IPN is verified, But once the IPN is verified I no longer have access to the tracking_id. My questions Why does paypal send two different IPN's Why are they different? Why isn't any of this documented on Paypal? :(

  • Best Ergonomic trackball (finger-operated, with scroll wheel) for programmer

    - by Clay Nichols
    We programmers are at great risk of RSI. After 10 years, I was having shoulder problems and switched to a trackball, which helped, then switched to my left hand which helped even more. I'm looking for a good finger-operated trackball with a scroll wheel. (I do not like the ones where you control the ball w/ your thumb. My thumb isn't as dexterous). I also want to have a scroll wheel. I currently use a Logitech Marble Mouse but the scrolling implementation is very poor. EDIT: I just tried the Marble Scroll (free software that provides better scrolling. Works great. Another option is the KatMouse addon (which I've not tried) for trackballs. I hear the old Logitech Trackman was very good, but is no longer available. Anyone have experience with the Marble Mouse (and the above fixes) ? Or any suggestions of a good trackball.

  • Windows Mobile Development on MacBook Pro?

    - by Ted Nichols
    I am a frequent Windows Mobile application developer in need of a new development laptop. I am considering a MacBook or Macbook Pro running either Fusion from VMWare or Parallels Desktop. This will give me the option to port my applications to the iPhone depending on what MS does with WM 6.5 and 7. Has anybody tried doing Windows Mobile development using Microsoft Windows Mobile Device Center (or ActiveSync) and VS2008 on the MacBook Pro using one of these virtual machines? Does the device emulator work properly? What about debugging a Windows Mobile device over a USB cable? In general, do most USB drivers (non HID) designed for Windows work under these virtual machines? Thanks.

  • How to record sound from a microphone in VB6?

    - by Clay Nichols
    We've been recording sound for over a decade using what seems like a very clunky method using the Winmm.dll and the MCIsendString. I've read that this doesn't set the recording quality value correctly (not sure if that article was ever true or is still true). I was wondering if there is any better way to record sound.

  • TortoiseSVN shows red ! decorator for folder, but no files within it are marked with !

    - by Clay Nichols
    I'm new to SVN. I'm using the latest version (svn 1.6.9, TortoiseSVN 1.6.7.18415). Some folders who a red exclamation point next to them. If I drill down, I find a sub folder with ! as well but no files within that are marked with ! (all are either a green checkmark or no icon (because they are Ignored (like .exe files) . What I've tried: Cleanup {reported success} Add {reports nothing to add. All files either under version control has been ignored per the .ignore property. Commit {succeeds} SVNupdate {succeeds} Restarted computer. Some oddities: -I had a bunch of CVS folders (these files were copied over from a PC that was using CVS but we don't need that version history so I didn't import it into SVN). I deleted those CVS\ folders and they are showing up (as unversioned files) when I CheckIn. Any ideas?

  • Softrware Licensing / Registration component/framework?

    - by Clay Nichols
    We use a home-grown Registration System for our software but I'd like to update it fixing a number of things including adding the ability to remotely activate/deactivate it (to facilitate Saas). Feel free to suggest any good (in your opinion) VB6- compatible option. I can check out whether it meets our other criteria below. Required Features: Activate multiple programs (Ok if it generates a separate code for each one) Works with VB6 and VB.net. A VB6-compatible DLL should be fine. Still supported (nice to have but not absolutely required Compatible with Windows 2000 through 7. Nice-to-have features (but not required) * Work without internet access * Works through a firewall (this may be a tough one) Any suggestions?

  • Mac CoreLocation Services does not ask for permissions

    - by Ryan Nichols
    I'm writing a Mac App that needs to use CoreLocation services. The code and location works fine, as long as I manually authenticate the service inside the security preference pane. However the framework is not automatically popping up with a permission dialog. The documentation states: Important The user has the option of denying an application’s access to the location service data. During its initial uses by an application, the Core Location framework prompts the user to confirm that using the location service is acceptable. If the user denies the request, the CLLocationManager object reports an appropriate error to its delegate during future requests. I do get an error to my delegate, and the value of +locationServicesEnabled is correct on CLLocationManager. The only part missing is the prompt to the user about permissions. This occurs on my development MPB and a friends MBP. Neither of us can figure out whats wrong. Has anyone run into this? Relevant code: _locationManager = [CLLocationManager new]; [_locationManager setDelegate:self]; [_locationManager setDesiredAccuracy:kCLLocationAccuracyKilometer]; ... [_locationManager startUpdatingLocation]; UPDATE: Answer It seems there is a problem with Sandboxing in which the CoreLocation framework is not allowed to talk to com.apple.CoreLocation.agent. I suspect this agent is responsible for prompting the user for permissions. If you add the Location Services Entitlement (com.apple.security.personal-information.location) it only gives your app the ability to use the CL framework. However you also need access to the CoreLocation agent to ask the user for permissions. You can give your app access by adding the entitlement 'com.apple.security.temporary-exception.mach-lookup.global-name' with a value of 'com.apple.CoreLocation.agent'. Users will be prompted for access automatically like you would expect. I've filed a bug to apple on this already.

  • Are there any open-source / free site analytics solutions that are intranet deployable?

    - by Richard Nichols
    There are plenty of statistics/analytics providers for Internet deployed software (e.g. Google Analytics), but I'm looking for an analytics tool to integrate into a LAN/intranet based web application. I'm aware of AWStats, but I'd prefer something with a design similar to Google Analytics, where a Javascript callback can be embedded into the app and call back to an analytics server. This doesn't require any sort of extra application server configuration and access to run. I'm thinking there's nothing available that isn't proprietary / pay-for, but I'd love to be told I'm wrong!

  • Tortoise SVN does not give option to "Add to SVN"

    - by Clay Nichols
    I've created an SVN repository and added folders and added contents and Committed. No problem. But when go to add a new folder (the others were on the P:\ drive, now I want to add our website which is on the C:\ drive) but Tortoise doesn't give me the option of Adding a folder. I have no idea why. Help file shows the instructions I'd expect ("right click on the folder you want to add and choose +Add...") but Add... isn't in the menu. This is TortoiseSVN v 1.6.7.18415 (I'm about to update it but I was able to add folders before so I don't think this is just a bug, I think maybe I'm missing something obvious).

  • retrieve comma delimited data from a field in using SQL

    - by Nichols
    I've created a form in php that collects basic information. I have a list box that allows multiple items selected (ie housing, rent, food, water). If multiple items are selected they are stored in a field called Needs seperated by a comma. I have created a report ordered by the persons needs. The people who only have one need are sorted correctly, but the people who have multiple are sorted exactly as the string passed to the database (ie. housing, rent, food, water) -- which is not what i want. Is there a way to seperate the multiple values in this field using SQL to count each need instance/occurance as 1 so that there are no comma delimitations shown in the results? CLICK FOR EXAMPLE

  • How to properly encode "[" and "]" in queries using Apache HttpClient?

    - by Jason Nichols
    I've got a GET method that looks like the following: GetMethod method = new GetMethod("http://host/path/?key=[\"item\",\"item\"]"); Such a path works just fine when typed directly into a browser, but the above line when run causes an IllegalArgumentException : Invalid URI. I've looked at using the URIUtils class, but without success. Is there a way to automatically encode this (or to add a query string onto the URL without causing HttpClient to barf?).

  • Are folks using the VB6 "Common Controls Replacement Project" controls? Any caveats or showstoppers?

    - by Clay Nichols
    I'm considering using the VB6 Common Controls Replacement Project controls and would like to see what other's experiences with them are. Specifically: What do you need to distribute with them? (I assume just the .OCX file) Do I need to register the .ocx file or just include in the app directory? Do these controls depend on any other ocx's? (There is mention, for example in the Progress Bar replacement that it is using COMCTL32.DLL but the .DEP file does not list that DLL. Are they at least as robust as the controls they replace?
