• Help, I need to debug my BrowserHelperObject (BHO) (in C++) after a internet explorer 8 crash in Rel

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• Creating installers in .net

  - by Manish

  I want to create a installer which would just dump few files and folders at a location specified by user. But the problem is these files are required to be picked up from a fixed source folder and then the installer is build. Also, these files may change any time and then again a new version of the installer is required to be created. I want to do this in .Net using Setup and Deployment project. I'm not sure how to do this. Do I need to create another class library project with a Setup Poject? Does anyone has any idea?

• gcc compiled binaries w/different sizes?

  - by BillTorpey

  If the same code is built at different times w/gcc, the resulting binary will have different contents. OK, I'm not wild about that, but that's what it is. However, I've recently run into a situation where the same code, built with the same version of gcc, is generating a binary with a different size than a prior build (by about 1900 bytes). Does anyone have any idea what may be causing either of these situations? Is this some kind of ELF issue? Are there any tools out there (other than ldd) that can be used to dump contents of binaries to see what exactly is different? Thanks in advance.

• Tomcat thread waiting on and locking the same resource

  - by Adam Matan

  Consider the following Java\Tomcat thread dump: "http-0.0.0.0-4080-4" daemon prio=10 tid=0x0000000019a2b000 nid=0x360e in Object.wait() [0x0000000040b71000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <0x00002ab5565fe358> (a org.apache.tomcat.util.net.JIoEndpoint$Worker) at java.lang.Object.wait(Object.java:485) at org.apache.tomcat.util.net.JIoEndpoint$Worker.await(JIoEndpoint.java:458) - locked <0x00002ab5565fe358> (a org.apache.tomcat.util.net.JIoEndpoint$Worker) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:484) at java.lang.Thread.run(Thread.java:662) Is this a deadlock? It seems that the same resource (0x00002ab5565fe358) is both locked and waited on - what does it mean?

• .resx file data inaccessible in Visual C#

  - by dsp_099

  What I'm trying to do: include some files along with the executable to extract them later. I have two projects, both with a Resource1.resx file (and some resources included from disk). In one project, I can use File.WriteAllBytes(path, Resource1.Image); to dump the resource to disk. In another, Resource1 is does not exist. I've done this before but all I can find is information about localizations (?) when I search MSDN for how to work with Resources.

• How to retrieve all keys (or values) from a std::map?

  - by Owen

  This is one of the possible ways I come out: struct RetrieveKey { template <typename T> typename T::first_type operator()(T keyValuePair) const { return keyValuePair.first; } }; map<int, int> m; vector<int> keys; // Retrieve all keys transform(m.begin(), m.end(), back_inserter(keys), RetrieveKey()); // Dump all keys copy(keys.begin(), keys.end(), ostream_iterator<int>(cout, "\n")); Of course, we can also retrieve all values from the map by defining another functor RetrieveValues. Is there any other way to achieve this easily? (I'm always wondering why std::map does not include a member function for us to do so.)

• How do I tell gdb how long my zero-length array is?

  - by Joe

  Slightly oxymoronic title! Bonus points for Xcode answer but it's a gdb question. If I have a standard, statically sized array gdb will print all its elements [and Xcode will let me browse through it] but if I have a zero length array, it won't, because it doesn't know. Obviously I can print the array indexes one by one, but I'd like a dump of the whole thing. How do I tell gdb how much space I have allocated for the array to allow it to print the array (or to allow Xcode to view the array). Is it even possible?

• Log your SQL in Rails application inside unit test

  - by Phuong Nguy?n

  I want to install a logger so that I can dump all executed SQL of my rails application. Problem is, such logger is associated with AbstractAdapter which initialized very soon under test mode, and thus cannot be set by my initializer code. I try to put ActiveRecord::Base.logger = MyCustomLogger.new(STDOUT) in the end of environment.rb like someone advised but it only works when being run in console environment (kicked by script/console), not when run under test mode. I wonder if there is any way to config such logger so that I will sure to be invoked under any environment (test, development, production, console)

• SSIS Migration - Pulling IDs from dest DB?

  - by TheSciz

  So I'm working on migrating some data to a new server. In the new server, each entry in the MAIN table is assigned a new GUID when the transfer takes place. A few other tables must be migrated, and their records must link to the GUID in the MAIN table. Example... WorksheetID --- GUID 1245677903 --- 1 AccidentID --- WorksheetID --- Guid 12121412 --- 1245677903 --- 1 The guid is used moreso for versioning purposes, but my question is this. In SSIS, is there any way to pull the Worksheet's GUID from the destination database and assign it directly to the entries in the 'Accident' table? Or do I have to just dump the data into the source DB and run some scripts to get everything nicely referenced? Any help would be greatly appreciated.

• C# Anyway to detect if an object is locked.

  - by scope-creep

  Hi, Is their anyway to determine if a object is locked in c#. I have the unenviable position, through design where i'm reading from a queue inside a class, and I need to dump the contents into a collection in the class. But that collection is also read/write from an interface outside the class. So obviously their may be a case when the collection is being written to, as the same time i want to write to it. I could program round it, say using delegate but it would be ugly. Bob.

• Object for storing strings in Python

  - by evg

  class MyWriter: def __init__(self, stdout): self.stdout = stdout self.dumps = [] def write(self, text): self.stdout.write(smart_unicode(text).encode('cp1251')) self.dumps.append(text) def close(self): self.stdout.close() writer = MyWriter(sys.stdout) save = sys.stdout sys.stdout = writer I use self.dumps list to store data obtained from prints. Is there a more convenient object for storing string lines in memory? Ideally I want dump it to one big string. I can get it like this "\n".join(self.dumps) from code above. May be it's better to just concatenate strings - self.dumps += text?

• INSERT INTO ... SELECT ... vs dumping/loading a file in MySQL

  - by Daniel Huckstep

  What are the implications of using a INSERT INTO foo ... SELECT FROM bar JOIN baz ... style insert statement versus using the same SELECT statement to dump (bar, baz) to a file, and then insert into foo by loading the file? In my messing around, I haven't seen a huge difference. I would assume the former would use more memory, but the machine that this runs on has 8GB of RAM, and I never even see it go past half used. Are there any huge (or long term) performance implications that I'm not seeing? Advantages/disadvantages of either?

• Android Terminal and Log Dumping

  - by J3hova

  I am trying to send terminal commands programmaticly from an android activity. At the moment I'm using something like the following: Process process = null; DataOutputStream os = null; process = Runtime.getRuntime().exec("su"); os = new DataOutputStream(process.getOutputStream()); os.writeBytes("./data/program1\n"); os.writeBytes("./data/program2\n"); os.writeBytes("exit\n"); os.flush(); However, my program1 is failing to run successfully and I believe it is due to inadequate user permissions. Now for my question: Does anyone know how I can dump the terminal to a file and save it on the phone or sdcard? The program is tying into the terminal to feed it commands, I want to know a way to open a connection the otherway and access the (what is normally visual on a terminal screen) output.

• send javaScript variable to php variable

  - by mrbunyrabit

  First i thought that i had to convert javascript to php, but then i found out that cant because of server and client side executions. So now I simply want to send ONE variable <script type="text/javascript"> function scriptvariable() { var theContents = "the variable"; } </script> to a php variable <?php $phpvariable ?> That function in the javascript executes when lets say i click on a button. Now i have Nooo idea how to get that phpvariable Equal to the javascript one so i can use that phpvariable to look up stuff in my Database. I know i can add it to my url or some thing, and just refresh the page.. But id like to do it with AJAX as further in my webpage i might have to use this Ajax method.. So is there an easy way to do this without having to dump pages of code on my page to do one simple thing?

• Creating CFArray from MySQL Result Array

  - by Andrew

  Is there an easy way to dump an array returned from mysql_fetch_row into a CFArray? (part of the PHP implementation of CFPropertyList) I'm bummed by the lack of documentation on CFPropertyList for PHP. Iterating through each item in the array seems inefficient. I'm open to using a different mysql_fetch_... command. I'd like to just say: $NewArray = new CFArray( $ResultArray ) But that deosn't seem to work. This is my current code: $plist = new CFPropertyList(); $ResultRow = mysqli_fetch_row( $result ); $plist-add( $TableRow = new CFArray() ); foreach ( $ResultRow as $Item ){ $TableRow-add( new CFString( $Item ) ); }

• Process incoming emails with script

  - by luckytaxi

  Remember iwantsandy.com? It was quite popular for what it did. ANyways, I'm looking to do something similar, but my question is, how does one process incoming emails? Let's assuming I'm using PHP or maybe even Ruby to do this. I would need a way to process the emails and dump them into a DB or something. Ok fine, but my main question is getting a script to kick off when an email comes in. I have a VPS so I have full control over my environment and it's running Centos.

• Facebook iframe app redirecting https to http, how?

  - by Paul Whitrow

  I'm trying to get an app working within Facebook, but it seems that no matter what I try including forcing just https in the app settings (see screen shot), the iframe source (Facebooks canvas) seems to change the https address to http (301) which is then producing SEC7111: HTTPS security errors in IE?

• CentOS 6 and Sun/Oracle Java Issue

• Trying to send XML via EMail and the XML includes a byte[]

  - by barbary

  Hello All, I want to send an email that has a machine readable part you cut and paste into an asp.net page and you get the information. I have stored all the information in an object and then used an XMLSerizer to create some xml. It all worked fine until I added some Images as byte[] to the object. If I dump the resulting string to disk then I can recreate the object fine but after it appears in the email client and I try to cut and paste it it never works. Clearly there are non standard characters coming out that email clients don't like. Is there some encoding I could apply to my XML that would make it display correctly in an email client? Then I could cut, paste, decode and deserilize to get my object back. Please an example of how to encode the string in c# would be great.

• How to migrate a codebase from one svn repo to another preserving history?

  - by chotchki

  I have a branch in a badly structured svn repo that needs to be stripped out and moved to another svn repository. (I'm trying to clean it up some). If I do an 'svn log' and not stop on copy/rename I can see all 3427 commits that I care about. Is there some way to dump the revisions out, short of writing some major scripts? I would follow the advice in this question but this branch has been moved all over the place and I would like to preserve the moves as well. Any ideas?

• downloading full page text from a web domain

  - by user362808

  Howdy, folks! First time here -- thought I'd field a question on behalf of a coworker. Somebody in my lab is doing a content analysis (e.g. reading an article or transcript line by line and identifying relevant themes) of the web presences of various privatized neuroimaging centers (e.g. http://www.canmagnetic.com/). She's been c/ping entire site maps by hand, and I know I could slap something together with Python to follow links and dump full text (with line numbers) for her, but I've never actually done anything quite like this. Any ideas for how I'd get started? Cheers, -alex

• How do i view the index version of a file before it is committed?

  - by lsiden

  I have just performed add --interactive, so the index version of some files is different than the working-directory versions. Instead of doing diff --cached, I want to actually dump the contents of each file in the index, but I can't find a command to do that. I should think that there would be something like "git show INDEX:filename...", but "INDEX" is not a valid object name. I was able to do git ls --cached, then git show , but there should be a more straightforward method to see what you are committing.

• Getting information about where c++ exceptions are thrown inside of catch block?

  - by tfinniga

  I've got a c++ app that wraps large parts of code in try blocks. When I catch exceptions I can return the user to a stable state, which is nice. But I'm not longer receiving crash dumps. I'd really like to figure out where in the code the exception is taking place, so I can log it and fix it. Being able to get a dump without halting the application would be ideal, but I'm not sure that's possible. Is there some way I can figure out where the exception was thrown from within the catch block? If it's useful, I'm using native msvc++ on windows xp and higher. My plan is to simply log the crashes to a file on the various users' machines, and then upload the crashlogs once they get to a certain size.

• Outer select column value in joined subquery?

  - by Michael DePetrillo

  Is it possible to use a column value from an outer select within a joined subquery? SELECT table1.id, table2.cnt FROM table1 LEFT JOIN (SELECT COUNT(*) as `cnt` FROM table2 where table2.lt > table1.lt and table2.rt < table1.rt) as table2 ON 1; This results in "Unknown column 'table1.lt' in 'where clause'". Here is the db dump. CREATE TABLE IF NOT EXISTS `table1` ( `id` int(1) NOT NULL, `lt` int(1) NOT NULL, `rt` int(4) NOT NULL) ENGINE=MyISAM DEFAULT CHARSET=latin1; CREATE TABLE IF NOT EXISTS `table2` ( `id` int(1) NOT NULL, `lt` int(1) NOT NULL, `rt` int(4) NOT NULL) ENGINE=MyISAM DEFAULT CHARSET=latin1; INSERT INTO `table1` (`id`, `lt`, `rt`) VALUES (1, 1, 4); INSERT INTO `table2` (`id`, `lt`, `rt`) VALUES (2, 2, 3);
