• Deploying a PyQt application on Windows Vista x64

  - by Skilldrick

  I'm working on an application for a client/friend using PyQt. I've been working on Linux and testing on Vista, but the target computer is Vista x64. Now, Python comes with compiled binaries of Python 2.6 for 64 bit Windows, but Riverbank don't provide 64 bit binaries for PyQt. I don't have much access to the target computer, so I can't really go through the hassle of compiling PyQt. This Google code project might be the solution, but I'm not sure if it's going to work. Can I use something like py2exe from 32 bit Vista, or would I have to have to make the executable from a 64 bit machine with PyQt 64 bit installed? Basically, am I going to have to compile PyQt on the target machine?

• POSIX-compatible regex library for Visual Studio C

  - by user1397061

  I'm working on a C program which will be run in Linux and from inside Visual Studio 2010, and I'm looking for a regex library. GNU comes with a POSIX-compatible regex library, but Visual Studio, despite having C++ std::regex, doesn't have a C-compatible library. GNU has a Windows version of their library (http://gnuwin32.sourceforge.net/packages/regex.htm), but the DLLs are 32-bit only and the source code can't compile in Visual Studio (~500 errors!). My only requirement is that the end-user should not have to install anything extra, and should get the same behaviour on both platforms. I'm not picky about whether it's POSIX-style, Perl-style or something else. What should I do? Thanks in advance.

• Account preferences crashes on ListPreference

  - by Sionide21

  I have created an account type using the AccountAuthenticator stuff as done in the SampleSyncAdapter tutorial. I am now trying to get account preferences working. I have added the line android:accountPreferences="@xml/account_preferences" to my account-authenticator and account_preferences.xml looks like so: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory android:title="@string/alum_settings_title"/> <CheckBoxPreference android:key="sync_alum" android:title="@string/sync_alum" android:summaryOn="@string/sync_alum_check" android:summaryOff="@string/sync_alum_nocheck"/> <ListPreference android:key="sync_alum_since" android:title="@string/alum_years" android:entries="@array/years" android:entryValues="@array/years" android:dependency="sync_alum"/> </PreferenceScreen> The checkbox preference works exactly like it should but the ListPreference crashes the entire system with the following message: 05-14 22:32:16.794: ERROR/AndroidRuntime(63): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application I get the same error with EditTextPreference and with the custom subclass of DialogPreference I created.

• XSD Schema for XML with multiple structures

  - by Xetius

  I am attempting to write an XML Schema to cover a number of XML conditions which I may encounter. I have the same root element (serviceRequest) with different child elements. I was trying to use the xs:extension element to define multiple versions, but it is complaining about unexpected element orderInclusionCriteria etc. Am I going about this the right way, or is there a better way to define this? The other way I thought about this was to have a single xs:choice with all the options inside it, but this seemed somewhat inelegant. These XSD files are for use within XMLBeans if that makes any difference. I have Given the following 2 examples of XML: 1) <?xml version="1.0" encoding="utf-8"?> <serviceRequest method="GOO" debug="NO"> <sessionId sID="ABC1234567" /> <orderInclusionCriteria accountId="1234567" accountNum="1234567890" /> </serviceRequest> 2) <?xml version="1.0" encoding="utf-8"?> <serviceRequest method="GOO" debug="NO"> <sessionId sID="ABC1234567" /> <action aType='MakePayment'> <makePayment accountID='CH91015165S' amount='5.00' /> </action> </serviceRequest> I thought I could use the following schema file: <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="serviceRequest" type="ServiceRequestType" /> <xs:element name="session" type="SessionType" /> <xs:attribute name="method" type="xs:string" /> <xs:attribute name="debug" type="xs:string" /> <xs:complexType name="SessionType"> <xs:attribute name="sID" use="required"> <xs:simpleType> <xs:restriction base="xs:string"/> </xs:simpleType> </xs:attribute> </xs:complexType> <xs:complexType name="ServiceRequestType"> <xs:sequence> <xs:element ref="session" /> </xs:sequence> <xs:attribute ref="method" /> <xs:attribute ref="debug" /> </xs:complexType> <xs:complexType name="OrderTrackingServiceRequest"> <xs:complexContent> <xs:extension base="ServiceRequestType"> <xs:complexType> <xs:sequence> <xs:element name="OrderInclusionCriteria" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="Action"> <xs:complexContent> <xs:extension base="ServiceRequestType"> <xs:complexType> <xs:sequence> <xs:element name="makePayment"> <xs:complexType> <xs:attribute name="accountID" type="xs:string" /> <xs:attribute name="amount" type="xs:string" /> <xs:complexType> </xs:element> </xs:sequence> <xs:attribute name="aType" type="xs:string" /> </xs:complexType> </xs:extension> </xs:complexContent> </xs:complexType> </xs:schema>

• Hook Response.Cache to memcache

  - by dvr

  Has anyone done this before? I have a 32 bit win 2003 server running 2.0 and have read the ms engineers' blog about min(60%, 1800mb) for cache limits and our site (asp.net 2.0 / 3.5) is caching alot. It throws system outofmemory exceptions when wp is around 1.3gb (unfortunately it is the 2.0 apps) and I would like to push alot over to memcache but worried that at the moment the site is efficient using response.cache as is (though memory is an issue). I want to move most items over to memcache and have concerns on a – how to do this (implementation of response.cache to read/write from memcache) and b – what will performance be like? Before I commit to doing this and possibly spending a few days running tests I would like to hear from you if this has been done already and get some feedback. (and please don’t tell me to buy a x64 machine – I have already requested this!), by the way I ran a test requesting a single image 1000 times and response.cache was over 50% quicker than using application cache. Does response.cache bypass the page lifecycle?

• How to read a CLOB column in Oracle using OleDb ?

  - by T.Falise

  Hi, I have created a table on an Oracle 10g database with this structure : create table myTable ( id number(32,0) primary key, myData clob ) I can insert rows in the table without any problem, but when I try to read data from the table using OleDb connection, I get an exception. Here is the code I use : using (OleDbConnection dbConnection = new OleDbConnection("ConnectionString")) { dbConnection.Open(); OleDbCommand dbCommand = dbConnection.CreateCommand(); dbCommand.CommandText = "SELECT * FROM myTable WHERE id=?"; dbCommand.Parameters.AddWithValue("ID", id); OleDbDataReader dbReader = dbCommand.ExecuteReader(); } The exception details seems to point on an unsupported data type : System.Data.OleDb.OleDbException: Unspecified error Oracle error occurred, but error message could not be retrieved from Oracle. Data type is not supported. Does anyone know how I can read this data using the OleDb connection ? PS : The driver used in this case is the Microsoft one.

• What's wront in this iban validation code?

  - by Jackoder

  Hello coders, I'm working on a php iban validator but i have a problem I wrote like this: function IbanValidator($value) { $iban = false; $value= strtoupper(trim($value)); # Change US text into your country code if(preg_match('/^US\d{7}0[A-Z0-9]{16}$/', $value)) { $number= substr($value,4,22).'2927'.substr($value,2,2); $number= str_replace( array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'), array(10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35), $number ); $iban = (1 == bcmod($number,97)) ? true; } return $iban; } Thanks.

• Mapping of memory addresses to physical modules in Windows XP

  - by Josef Grahn

  I plan to run 32-bit Windows XP on a workstation with dual processors, based on Intel's Nehalem microarchitecture, and triple channel RAM. Even though XP is limited to 4 GB of RAM, my understanding is that it will function with more than 4 GB installed, but will only expose 4 GB (or slightly less). My question is: Assuming that 6 GB of RAM is installed in six 1 GB modules, which physical 4 GB will Windows actually map into its address space? In particular: Will it use all six 1 GB modules, taking advantage of all memory channels? (My guess is yes, and that the mapping to individual modules within a group happens in hardware.) Will it map 2 GB of address space to each of the two NUMA nodes (as each processor has it's own memory interface), or will one processor get fast access to 3 GB of RAM, while the other only has 1 GB? Thanks!

• Java variadic function parameters

  - by Amir Rachum

  Hi, I have a function that accepts a variable number of parameters: foo (Class... types); In which I get a certain number of class types. Next, I want to have a function bar( ?? ) That will accepts a variable number of parameters as well, and be able to verify that the variables are the same number (that's easy) and of the same types (the hard part) as was specified in foo. How can I do that? Edit: to clarify, a call could be: foo (String.class, Int.class); bar ("aaa", 32); // OK! bar (3); // ERROR! bar ("aa" , "bb"); //ERROR! Also, foo and bar are methods of the same class.

• Creating a spider using Scrapy, Spider generation error.

  - by Nacari

  I just downloaded Scrapy (web crawler) on Windows 32 and have just created a new project folder using the "scrapy-ctl.py startproject dmoz" command in dos. I then proceeded to created the first spider using the command: scrapy-ctl.py genspider myspider myspdier-domain.com but it did not work and returns the error: Error running: scrapy-ctl.py genspider, Cannot find project settings module in python path: scrapy_settings. I know I have the path set right (to python26/scripts), but I am having difficulty figuring out what the problem is. I am new to both scrapy and python so there is a good possibility that I have failled to do something important. Also, I have been using eclipse with the Pydev plugin to edit the code if that might cause some problems.

• SIP servlets, chatserver

  - by Senne

  I'm trying to get a SIP servlet chat server working, together with the textclient found here. When I use 2 clients to send messages to eachother (peer to peer), everything goes well. But when I use one or more clients together with my server, I have to wait exactly 32 seconds before the server picks up any new messages in the doMessage() method. I'm using Netbeans together with Sailfin as my SIP server. Is there some kind of limitation or configurable delay or timeout between requests or responses in Sailfin I'm looking over? I can post the server code, if needed. Thanks

  Hi, I have a program that is compressing a string in an unknown way. I know a few inputs and the output produced, but I am not sure what is being used to compress the string. Here are my examples. (just 38 x a, no spaces or anything else) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" Out: "026900211AA63000026900"   (just 32 x a) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" Out: "0209001c1aa7a000020900" (31 x a, then 1 b) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaab" Out: "0209000177c553c000020900" (31 x b, then 1 a) In: "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbba" Out: "0209001e7754f38000020900" In: "Hey wot u doing 2day u wanna do something" Out: "02990011C7C62E78CE6B8E3ACD83E81B37C5C5A6B9D1E1B06963DB5E71155C1000029900" (same as previous string, but with a space at the end) In: "Hey wot u doing 2day u wanna do something " Out: "02A90012C7718B9E339AE2EB360FA02CDF17177A674786DF4B1EDAF388AAE08000000002A90000" The only definite thing I can see so far is digit 2 and 3 are the amount of characters (hex value), ie first one is 26 = 38 Also the first 6 digits are repeated at the end Any help / advice would be great, thanks!

• Variable-byte encoding clarification

  - by Myx

  Hello: I am very new to the world of byte encoding so please excuse me (and by all means, correct me) if I am using/expressing simple concepts in the wrong way. I am trying to understand variable-byte encoding. I have read the Wikipedia article (http://en.wikipedia.org/wiki/Variable-width_encoding) as well as a book chapter from an Information Retrieval textbook. I think I understand how to encode a decimal integer. For example, if I wanted to provide variable-byte encoding for the integer 60, I would have the following result: 1 0 1 1 1 1 0 0 (please let me know if the above is incorrect). If I understand the scheme, then I'm not completely sure how the information is compressed. Is it because usually we would use 32 bits to represent an integer, so that representing 60 would result in 1 1 1 1 0 0 preceded by 26 zeros, thus wasting that space as opposed to representing it with just 8 bits instead? Thank you in advance for the clarifications.

• How do I send an email with embedded images AND regular attachments in JavaMail?

  - by Chris

  Hi, I'd like to know how to build an SMTP multipart message in the correct order so that it will render correctly on the iPhone mail client (rendering correctly in GMail). I'm using Javamail to build up an email containing the following parts: A body part with content type "text/html; UTF-8" An embedded image attachment. A file attachment I am sending the mail via GMail SMTP (via SSL) and the mail is sent and rendered correctly using a GMail account, however, the mail does not render correctly on the iPhone mail client. On the iPhone mail client, the image is rendered before the "Before Image" text when it should be rendered afterwards. After the "Before Image" text there is an icon with a question mark (I assume it means it couldn't find the referenced CID). I'm not sure if this is a limitation of the iPhone mail client or a bug in my mail sending code (I strongly assume the latter). I think that perhaps the headers on my parts might by incorrect or perhaps I am providing the multiparts in the wrong order. I include the text of the received mail as output by gmail (which renders the file correc Message-ID: <[email protected]> Subject: =?UTF-8?Q?Test_from_=E3=82=AF=E3=83=AA=E3=82=B9?= MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="----=_Part_0_20870565.1274154021755" ------=_Part_0_20870565.1274154021755 Content-Type: application/octet-stream Content-Transfer-Encoding: base64 Content-ID: <20100518124021763_368238_0> iVBORw0K ----- TRIMMED FOR CONCISENESS 6p1VVy4alAAAAABJRU5ErkJggg== ------=_Part_0_20870565.1274154021755 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 7bit <html><head><title>Employees Favourite Foods</title> <style> body { font: normal 8pt arial; } th { font: bold 8pt arial; white-space: nowrap; } td { font: normal 8pt arial; white-space: nowrap; } </style></head><body> Before Image<br><img src="cid:20100518124021763_368238_0"> After Image<br><table border="0"> <tr> <th colspan="4">Employees Favourite Foods</th> </tr> <tr> <th align="left">Name</th><th align="left">Age</th><th align="left">Tel.No</th><th align="left">Fav.Food</th> </tr> <tr style="background-color:#e0e0e0"> <td>Chris</td><td>34</td><td>555-123-4567</td><td>Pancakes</td> </tr> </table></body></html> ------=_Part_0_20870565.1274154021755 Content-Type: text/plain; charset=us-ascii; name=textfile.txt Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=textfile.txt This is a textfile with numbers counting from one to ten beneath this line: one two three four five six seven eight nine ten(no trailing carriage return) ------=_Part_0_20870565.1274154021755-- Even if you can't assist me with this, I would appreciate it if any members of the forum could forward me a (non-personal) mail that includes inline images (not external hyperlinked images though).

• Write data to an xml file.

  - by Bobby

  My aim is to write an XML file with few tags whose values are the regional language. I'm using Python to do this and using IDLE(Pythong GUI) for programming. While I try to write the words in an xmls file it gives the following error. UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128) For now, I'm not using any xml writer library instead I'm opening a file "test.xml" and writing the data into it. This error is encountered by the line: f.write("\t\" + data + "\"). If I replace the above write statement with print statement then it prints the data properly on Python Shell. I'm reading the data from an excel file which is not in the UTF8,16, or 32 encoding formats. Its in some other format. cp1252 is reading the data properly. Any help in getting this data writtent oan xml would be highly appreciated. Thanks in advance. Bob

• avr-gcc Atmel AVR microncontrollers on Linux / Windows Arduino IDE

  - by Prakash

  I recently heard all about avr-gcc and avr-lib support on Linux that can be used for developing code for Atmel AVR micro-controller (ATmega48/88/168, ATmega16/32). I also understand that Arduino also uses Atmel's AVR micro-controller (I am not sure which one). Now different vendors have designed their own product (using Atmel AVR uc) where code is to be developed using avr-gcc i.e. on Linux platform. In the same regards Arduino's Windows IDE is much simpler and easy to code with. I am confused as to which platform is more promising - what are the benefits of learning avr-gcc? Which is the better option to program using the same? What type of application can we develop using avr-gcc compiler?

  Hello oh great wizards of all things android. I really need your help. Mostly because my little brain just doesn't know were to start.

• ODBC datasource for DB2 on 64 bit Windows 2008

  - by Rob Vermeulen

  First of all, sorry for this non-programming question. I just finished development of some code that communicates with DB2 and want to test/deploy it on a Windows 2008 machine. I'm a bit concerned about not being able to find a working ODBC datasource (DSN/client) driver for DB2 on Windows 2008 (x64). I have a 32-bit driver for XP but that one (obviously) won't install on 2008-64. The IBM web site comes up with 1844 results when searching for "ODBC Windows 2008", but none of them are relevant. The web site's also a pain to use, btw. While googling around I found some solutions by 3rd party vendors but they all want money :) And the DB2 client and ODBC driver from IBM have always been free-of-charge. Does anyone have a solution?

• What is the bit size of long on 64-bit Windows?

  - by acidzombie24

  Not to long ago someone told me that long are not 64 bits on 64 bit machines and i should always use int. This did not make sense to me. I seen docs (such as the one on apples official site) say that long are indeed 64 bits when compiling for a 64bit CPU. I looked up what it was on windows and found Windows: long and int remain 32-bit in length, and special new data types are defined for 64-bit integers. from http://www.intel.com/cd/ids/developer/asmo-na/eng/197664.htm?page=2 What should i use? should i define something like uw, sw ((un)signed width) as a long if not on windows. Otherwise do a check on the target CPU bitsize?
