  • The different of SHA512 between openssl and php

    - by solomon_wzs
    Here is C code: #include <openssl/sha.h> #include <stdio.h> char *hash_sha512(char *data){ SHA512_CTX ctx; char *md=malloc(sizeof(char)*(SHA512_DIGEST_LENGTH+1)); SHA512_Init(&ctx); SHA512_Update(&ctx, data, strlen(data)); SHA512_Final(md, &ctx); md[SHA512_DIGEST_LENGTH]='\0'; return md; } int main(int argc, char *argv[]){ str=hash_sha512("GFLOuJnR19881218"); printf("%s\n", str); free(str); return 1; } The output: ?<?4????IIA[r?? ?#? 6p?8jD????J?b9?????^X? Here is PHP code: $hash=hash('sha512', 'GFLOuJnR19881218', TRUE); The output: ?<??4??j??II?-A[r???? ??#??D6p?8jD???????J?b9?????^X? The results of C code and PHP code are different, what is wrong with my code?

  • LINQ2SQL: How to let a column accept null values as zero (0) in Self-Relation table

    - by Remon
    As described in the img, I got a parent-Children relation and since the ParentID not accepting null values (and I can't change to nullabel due to some restriction in the UI I have), how can I remove an existence relation between ReportDataSources in order to change the parent for them (here i want to set the parentId for one of them = 0) how could i do that since i cant change the ParentID directly and setting Parent = null is not valid public void SetReportDataSourceAsMaster(ReportDataSource reportDataSource) { //Some logic - not necessarily for this scenario //Reset Master this.ReportDataSources.ToList().ForEach(rds => rds.IsMaster = false); //Set Master reportDataSource.IsMaster = true; //Set Parent ID for the rest of the Reports data sources this.ReportDataSources.Where(rds => rds.ID != reportDataSource.ID).ToList().ForEach(rds => { //Change Parent ID rds.Parent = reportDataSource; //Remove filttering data rds.FilteringDataMembers.Clear(); //Remove Grouping Data rds.GroupingDataMembers.Clear(); }); //Delete parent HERE THE EXCEPTION THROWN AFTER CALLING SUBMITCHANGES() reportDataSource.Parent = null; //Other logic } Exception thrown after calling submitChanges An attempt was made to remove a relationship between a ReportDataSource and a ReportDataSource. However, one of the relationship's foreign keys (ReportDataSource.ParentID) cannot be set to null.

  • getting string.substring(N) not to choke when N > string.length

    - by aape
    I'm writing some code that takes a report from the mainframe and converts it to a spreadsheet. They can't edit the code on the MF to give me a delimited file, so I'm stuck dealing with it as fixed width. It's working okay now, but I need to get it more stable before I release it for testing. My problem is that in any given line of data, say it could have three columns of numbers, each five chars wide at positions 10, 16, and 22. If on this one particular row, there's no data for the last two cols, it won't be padded with spaces; rather, the length of the string will be only 14. So, I can't just blindly have dim s as string = someStream.readline a = s.substring(10, 5) b = s.substring(16, 5) c = s.substring(22, 5) because it'll choke when it substrings past the length of the string. I know I could test the length of the string before processing each row, and I have automated the filling of some of the vsariables using a counter and a loop, and using the counter*theWidthOfTheGivenVariable to jump around, but this project was a dog to start with (come on! turning a report into a spreadsheet?), but there are many different types of rows (it's not just a grid), and the code's getting ugly fast. I'd like this to be clean, clear, and maintainable for the poor sucker that gets this after me. If it matters, here's my code so far (it's really crufty at the moment). You can see some of my/its idiocy in the processSection#data subs So, I'm wondering 1) is there a way baked in to .NET to have string.substring not error when reading past the end of a string without wrapping it in a try...catch? and 2) would it be appropriate in this situation to write a new string class that inherits from string that has a more friendly substring function in it? ETA: Thanks for all the advice and knowledge everyone. I'll go with the extension. Hopefully one of these years, I'll get my chops up enough to pay someone back in kind. :)

  • How to get a UIAlertView's result??

    - by cocos2dbeginner
    Hi, I implemented the gamekit. All works fine now. But if the user presses on send the data will instantly send to the other iphone/ipod/ipad and it will instantly written. So now i wanted to implemenr a confirm screen for the receiver. In my receiveData method (from the gamekit) i have an array. If the user presses yes the array will be written into a file.if not it wont be written into a file. #pragma mark - #pragma mark - GKreceiveData - (void) receiveData:(NSData *)data fromPeer:(NSString *)peer inSession: (GKSession *)session context:(void *)context { NSDictionary *dict = [NSKeyedUnarchiver unarchiveObjectWithData:data]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Incoming Set" message:[NSString stringWithFormat:@"%@ wants to send you a Set named: \n\n %@",[session displayNameForPeer:peer], [dict valueForKey:@"SetName"]] delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil]; [alert show]; [alert release]; } - (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { // the user clicked one of the OK/Cancel buttons if (buttonIndex == 0) { //NSLog(@"ok"); //this should happen if the user presses on ok on the alertview.

  • Best way to validate currency input?

    - by Abe Miessler
    I have created the TextBox and CompareValidator below which I thought would allow input in the following forms: 5 5.00 $5.00 Unfortunately it's not allowing the version with the dollar sign in it. What is the point of doing a type check against currency if you don't allow the dollar sign? Is there a way to allow this symbol? <asp:TextBox ID="tb_CostShare" runat="server" Text='<%# Eval("CostShare", "{0:$0.00}")%>' CausesValidation="true" /> <asp:CompareValidator ID="vld_CostShare" runat="server" ControlToValidate="tb_CostShare" Operator="DataTypeCheck" Type="Currency" ValidationGroup="vld" ErrorMessage="You must enter a dollar amount for 'Cost Share'." />

  • jQuery ajax response not operating correctly

    - by mmarceau
    Ok this is frustrating... The code below works "correctly" as far as sending the email address to the SaveEmail URL and it gets saved correctly each time I change the drop down. However it only outputs the "Successful" message once, no matter how many times I change the value in the drop down. The "data" that is returned is "Successful". I would like to show the message for a couple seconds, then fade it out. It works correctly the first time I change the drop down, after that the change happens and the value gets saved, but the "Successful" message doesn't display. jQuery code: $('#AgentEmails').change(function() { var NewAddress = $('#AgentEmails').val(); $.post('SaveEmail.aspx', { email: NewAddress }, function(data) { $('#SelectMsg').html("<b>" + data + "</b>").fadeOut(); }); }); HTML code: <select ID='AgentEmails' runat='server'> <option value="[email protected]">TEST</option> </select><span id='SelectMsg'></span> What needs to be changed in my code to make this operate correctly? Thanks for the help.

  • Can I pass a non-generic type where a generic type is expected?

    - by Water Cooler v2
    I want to define a set of classes that collect and persist data. I want to call them either on-demand basis, or in a chain-of-responsibility fashion, as the caller pleases. To support the chaining, I have declared my interface like so: interface IDataManager<T, K> { T GetData(K args); void WriteData(Stream stream); void WriteData(T data, Stream stream); IDataCollectionPolicy Policy; IDataManager<T, K> NextDataManager; } But the T's and K's for each concrete types will be different. If I give it like this: IDataManager<T, K> NextDataManager; I assume that the calling code will only be able to chain types that have the same T's and K's. Is there a way I can have it chain any type of IDataManager? One thing that occurs to me is to have IDataManager inherit from a non-generic IDataManager like so: interface IDataManager { } interface IDataManager<T, K>: IDataManager { T GetData(K args); void WriteData(Stream stream); void WriteData(T data, Stream stream); IDataCollectionPolicy Policy; IDataManager NextDataManager; } Is this going to work?

  • UDP: Client started before Server

    - by Chris
    I have a bit of a glitch in my game just now, everything runs fine if the server is started before the client however when the client is started before the server they never connect. This is all UDP The problem happens when the client tries to call recvfrom() before the server has started, when this happens the client never finds the server and the server never finds the client. The resulted error is a wouldblock. If I stop the client using recvfrom and start the client before the server (the client is still sending data its just not receiving it) they both find each other no problem. Whats the solution for this? The way its seems just now is that the client cannot call recvfrom without a server being active or it all falls apart. Is there a check that can be done to see if data is sitting on a certain port(data the server would send)? Or is there a better way to do this? Some Code... Server Operation - UDPSocket is a class UDPSocket.Initialise(); UDPSocket.MakeNonBlocking(); UDPSocket.Bind(LOCALPORT); int n = UDPSocket.Receive(&thePacket); if (n > 0) UDPSocket.Send(&sendPacket); Client... UDP.Initialise(); UDP.MakeNonBlocking(); UDP.SetDestinationAddress(SERVERIP, SERVERPORT); serverStatus = UDP.Receive(&recvPacket); if (serverStatus > 0) { //Do some things UDP.Send(dPacket); //Try and reconnect with server } Thanks

  • Exchange Server 2010: move mailboxes from recoveded and mounted edb to user's mailbox [closed]

    - by Cook
    One of our exchange servers crashed, and I am trying to recover the mailboxes. We had 1 exchange 2003 server named "apex" and 1 exchange 2010 server named "2008Enterprise. the exchange 2010 server named "2008Enterprise" crashed. I created a new exchange 2010 server named "Providence". I ran the command on Providence: New-MailboxDatabase -Recovery -Name JBCMail -Server Providence -EdbFilePath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147\Mailbox Database 0579285147.edb" -LogFolderPath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147" this command executed and finished without error I then ran the command: eseutil /p E00 this command was executed from the below directory: c:\data\Exchange\Mailbox\Mailbox Database 0579285147 I then mounted the JBCMail with the mount command note: I do not have my full typed command. Inside my Exchange Management Console (EMC) I can view the new mailbox database named JBCMail. The JBCMail database is show as mounted on the exchange server named Providence. I can see the crashed Exchange server named 2008Exchange. In the EMC the crashed exchange server states the Copy Status under ServerConfiguration-Mailbox is ServiceDown. From here I need to recover three mailboxes The mail boxes are on the apex server. How do I move the mailboxs from apex to Providence? How do I restore the mailboxes from JBCmail mounted database to the user's mailbox? I do not fully understand how to use the Restore-Mailbox command because when I use this command it tries to restore the mailbox to the dead apex server.

  • C++ Design Question on template types

    - by user231536
    I have a templated class template <typename T> class MyContainerClass For types to be substituted for T, it has to satisfy many requirements: for example, get_id(), int data(), etc. Obviously none of the fundamental types (PODs) are substitutable. One way I can provide this is via wrappers for the PODs that provide these functions. Is this an acceptable way? Another way would be to change the template to: template < typename T, typename C=traits<T> > class MyContainerClass and inside MyContainerClass, call traits::data() instead of data() on T objects. I will specialize traits<int>, traits<const char *> etc. Is this good design ? How do I design such a traits class (completely static methods or allow for inheritance) ? Or are the wrapper classes a good solution? What other alternatives are there?

  • Why SQL functions are faster than UDF

    - by Zerotoinfinite
    Though it's a quite subjective question but I feel it necessary to share on this forum. I have personally experienced that when I create a UDF (even if that is not complex) and use it into my SQL it drastically decrease the performance. But when I use SQL inbuild function they happen to work pretty faster. Conversion , logical & string functions are clear example of that. So, my question is "Why SQL in build functions are faster than UDF"? and it would be an advantage if someone can guide me how can I judge/manipulate function cost either mathematically or logically.

  • Write-Only Reference in C++?

    - by Robert Mason
    Is there a way to code a write-only reference to an object? For example, suppose there was a mutex class: template <class T> class mutex { protected: T _data; public: mutex(); void lock(); //locks the mutex void unlock(); //unlocks the mutex T& data(); //returns a reference to the data, or throws an exception if lock is unowned }; Is there a way to guarantee that one couldn't do this: mutex<type> foo; T& ref; foo.lock(); ref = foo.data(); foo.unlock(); //I have a unguarded reference to foo now On the other hand, is it even worth it? I know that some people assume that programmers won't deliberately clobber the system, but then, why do we have private variables in the first place, eh? It'd be nice to just say it's "Undefined Behavior", but that just seems a little bit too insecure.

  • SQL Server query

    - by carrot_programmer_3
    Hi, I have a SQL Server DB containing a registrations table that I need to plot on a graph over time. The issue is that I need to break this down by where the user registered from (e.g. website, wap site, or a mobile application). the resulting output data should look like this... [date] [num_reg_website] [num_reg_wap_site] [num_reg_mobileapp] 1 FEB 2010,24,35,64 2 FEB 2010,23,85,48 3 FEB 2010,29,37,79 etc... The source table is as follows... UUID(int), signupdate(datetime), requestsource(varchar(50)) some smple data in this table looks like this... 1001,2010-02-2:00:12:12,'website' 1002,2010-02-2:00:10:17,'app' 1003,2010-02-3:00:14:19,'website' 1004,2010-02-4:00:16:18,'wap' 1005,2010-02-4:00:18:16,'website' Running the following query returns one data column 'total registrations' for the website registrations but I'm not sure how to do this for multiple columns unfortunatly.... select CAST(FLOOR(CAST([signupdate]AS FLOAT ))AS DATETIME) as [signupdate], count(UUID) as 'total registrations' FROM [UserRegistrationRequests] WHERE requestsource = 'website' group by CAST(FLOOR(CAST([signupdate]AS FLOAT ))AS DATETIME)

  • Stop SQL returning the same result twice in a JOIN

    - by nbs189
    I have joined together several tables to get data i want but since I am new to SQL i can't figure out how to stop data being returned more than once. her's the SQL statement; SELECT T.url, T.ID, S.status, S.ID, E.action, E.ID, E.timestamp FROM tracks T, status S, events E WHERE S.ID AND T.ID = E.ID ORDER BY E.timestamp DESC The data that is returned is something like this; +----------------------------------------------------------------+ | URL | ID | Status | ID | action | ID | timestamp | +----------------------------------------------------------------+ | T.1 | 4 | hello | 4 | has uploaded a track | 4 | time | | T.2 | 3 | bye | 3 | has some news | 3 | time | | t.1 | 4 | more | 4 | has some news | 4 | time | +----------------------------------------------------------------+ That's a very basic example but does outline what happens. If you look at the third row the URL is repeated when there is a different status. This is what I want to happen; +-------------------------------------------------------+ | URL or Status | ID | action | timestamp | +-------------------------------------------------------+ | T.1 | 4 | has uploaded a track | time | | hello | 3 | has some news | time | | bye | 4 | has some news | time | +-------------------------------------------------------+ Please notice that the the url (in this case the mock one is T.1) is shown when the action is has uploaded a track. This is very important. The action in the events table is inserted on trigger of a status or track insert. If a new track is inserted the action is 'has uploaded a track' and you guess what it is for a status. The ID and timestamp is also inserted into the events table at this point. Note: There are more tables that go into the query, 3 more in fact, but I have left them out for simplicity.

  • Rails 3 MySQL 2 reports an error in what looks to be valid SQL syntax

    - by John Judd
    I am trying to use the following bit of code to help in seeding my database. I need to add data continually over development and do not want to have to completely reseed data every time I add something new to the seeds.rb file. So I added the following function to insert the data if it doesn't already exist. def AddSetting(group, name, value, desc) Admin::Setting.create({group: group, name: name, value: value, description: desc}) unless Admin::Setting.find_by_sql("SELECT * FROM admin_settings WHERE group = '#{group}' AND name = '#{name}';").exists? end AddSetting('google', 'analytics_id', '', 'The ID of your Google Analytics account.') AddSetting('general', 'page_title', '', '') AddSetting('general', 'tag_line', '', '') This function is included in the db/seeds.rb file. Is this the right way to do this? However I am getting the following error when I try to run it through rake. rake aborted! Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'group = 'google' AND name = 'analytics_id'' at line 1: SELECT * FROM admin_settings WHERE group = 'google' AND name = 'analytics_id'; Tasks: TOP => db:seed (See full trace by running task with --trace) Process finished with exit code 1 What is confusing me is that I am generating correct SQL as far as I can tell. In fact my code generates the SQL and I pass that to the find_by_sql function for the model, Rails itself can't be changing the SQL, or is it? SELECT * FROM admin_settings WHERE group = 'google' AND name = 'analytics_id'; I've written a lot of SQL over the years and I've looked through similar questions here. Maybe I've missed something, but I cannot see it.

  • Formating a date field in the Model (Codeigniter)

    - by Landitus
    Hi, I', trying to re-format a date from a table in Codeigniter. The Controller is for a blog. I was succesfull when the date conversion happens in the View. I was hoping to convert the date in the Model to have things in order. This is the Model: class Novedades_model extends Model { function getAll() { $this->db->order_by('date','desc'); $query = $this->db->get('novedades'); if($query->num_rows() > 0) { foreach ($query->result() as $row) { $data[] = $row; } } return $data; } } This is part of the controller $this->load->model('novedades_model'); $data['records'] = $this->novedades_model->getAll(); Here's the date conversion as it happens in the View. This is inside the posts loop: <?php foreach($records as $row) : ?> <?php $fdate = "%d <abbr>%M</abbr> %Y"; $dateConv = mdate($fdate, mysql_to_unix($row->date)); ?> <div class="article section"> <span class="date"><?php echo $dateConv ;?></span> ... Keeps going ... How can I convert the date in the Model? Can I access the date key and refactor it?

  • One-to-many Associations Empty Columns Issue (Ext on Rails)

    - by Joe
    I'm playing with rewriting part of a web application in Rails + Ext. However, I'm having trouble getting an associated models' name to display in the grid view. I've been able to successfully convert several models and arrange the views nicely using tabs and Ext's layout helpers. However, I'm in the middle of setting up an association -- I've followed along with Jon Barket's tutorial on how to do this using Ext -- and I've made all the Rails and JS changes suggested (with appropriate name changes for my models,) the result being that the combo box is now being correctly populated with the names of the associated models, and changes are actually written correctly to database, BUT the data doesn't show up in the column, it's just empty. However, the correct data is there in the 'detail' view. Really just wondering if anyone else ran into this, or had any thoughts on what could be happening. Definitely willing to post code if requested; just note that (AFAIK) my changes follow the tutorial pretty closely. Thanks in advance! UPDATE: Alright, slight progress - kind of. I can get the associated model id # displaying properly -- just by modifying the column model slightly. But I can't get the virtual attribute displayed in the main table (in Jon's example it's country_name.) It still goes blank when I change the data source for that column from dataIndex: 'model[associated_model_id]' to dataIndex: 'virtual_attributes[associated_model_name]' ANOTHER UPDATE: Bump. Has NOBODY here tried integrating Ext with Rails?

  • SCons and dependencies for python function generating source

    - by elmo
    I have an input file data, a python function parse and a template. What I am trying to do is use parse function to get dictionary out of data and use that to replace fields in template. Now to make this a bit more generic (I perform the same action in few places) I have defined a custom function to do so. Below is definition of custom builder and values is a dictionary with { 'name': (data_file, parse_function) } (you don't really need to read through this, I simply put it here for completeness). def TOOL_ADD_FILL_TEMPLATE(env): def FillTemplate(env, output, template, values): out = output[0] subs = {} for name, (node, process) in values.iteritems(): def Process(env, target, source): with open( env.GetBuildPath(target[0]), 'w') as out: out.write( process( source[0] ) ) builder = env.Builder( action = Process ) subs[name] = builder( env, env.GetBuildPath(output[0])+'_'+name+'_processed.cpp', node )[0] def Fill(env, target, source): values = dict( (name, n.get_contents()) for name, n in subs.iteritems() ) contents = template[0].get_contents().format( **values ) open( env.GetBuildPath(target[0]), 'w').write( contents ) builder = env.Builder( action = Fill ) builder( env, output[0], template + subs.values() ) return output env.Append(BUILDERS = {'FillTemplate': FillTemplate}) It works fine when it comes to checking if data or template changed. If it did it rebuilds the output. It even works if I edit process function directly. However if my process function looks like this: def process( node ): return subprocess(node) and I edit subprocess the change goes unnoticed. Is there any way to get correct builds without making process functions being always invoked?

    For inserting special characters in data like (,')etc., I am using musql_real_escape_string() function & it's working fine. Now I want to use same variable while inserting values in Oracle. $str = 'N.G.Palace\'s Building', 'xyzcity', '12345678','India','100001',12 Here $str is result of mysql_real_escape_string(). so it escapes special character. Now my code for oracle is like this-: $qry ="INSERT INTO Ora_table(ship_to_street, ship_to_city,ship_to_country, ship_to_telephone, order_id, record_no) VALUES(".$str); So my doubt is Oracle is not accepting values return by mysql_real_escape_string i.e. Palace\'s (like this as this mysql function attach \ before 'single quote)? So can anybody tell me ho9w can I use that variable $str to insert data into Oracle? Also I tried like this also-: "q"."'"."c".$str."c"."'" can we use this for multiple values like in my case...though still I am unable to inser data in oracle? plz help.

  • when to use Hibernate vs. Simple ResultSets for small application

    - by luke
    I just started working on upgrading a small component in a distributed java application. The main application is a rather complicated applet/servlet combo running on JBoss and it extensively uses Hibernate for its DataAccess. The component i am working on however is very a very straightforward data importing service. Basically the workflow is Listen for a network event Parse the data packet, extract a set of identifiers Map the identifier set to a primary key in our database Parse the rest of the packet and insert items in a related table using the foreign key found in step 3 Repeat in the previous version of this component it used a hibernate based DAL, that is no longer usable for a variety of reasons (in particular it is EOL), so I am in charge of replacing the Data Access layer for this component. So on the one hand I think i should use Hibernate because that's what the rest of the application does, but on the other i think i should just use regular java.sql.* classes because my requirements are really straightforward and aren't expected to change any time soon. So my question is (and i understand it is subjective) at what point do you think that the added complexity of using an ORM tool (in terms of configuration, dependencies...) is worth it? UPDATE due to the way the DataAccesLayer for the main application was written (weird dependencies) i cannot easily use it, i would have to implement it myself.

  • How can I find out how much memory an object of a C++ class consumes?

    - by Shadow
    Hi, I am developing a Graph-class, based on boost-graph-library. A Graph-object contains a boost-graph, so to say an adjacency_list, and a map. When monitoring the total memory usage of my program, it consumes quite a lot (checked with pmap). Now, I would like to know, how much of the memory is exactly consumed by a filled object of this Graph-class? With filled I mean when the adjacency_list is full of vertices and edges. I found out, that using sizeof() doesn't bring me far. Using valgrind is also not an alternative as there is quite some memory allocation done previously and this makes the usage of valgrind impractical for this purpose. I'm also not interested in what other parts of the program cost in memory, I want to focus on one single object. Thank you.

  • How to update MySQL table with a cumulative count of events with the same date

    - by John
    I have a table which I pull data from. This data has a date and a stock symbol. There can be multiple rows of data with the same date and different stock symbols. I need to update the table so that there is a running total for all rows with the same date. When a new date occurs the cumulative count re-sets to 1 and then resumes. A typical query: mysql> SELECT Sym 'sym' , fdate as 'FilledDate', TsTradeNum 'numT' -> FROM trades_entered_b2 -> WHERE fDate >= '2009-08-03' AND fDate <= '2009-08-07' -> LIMIT 10; +------+------------+------+ | sym | FilledDate | numT | +------+------------+------+ | WAT | 2009-08-03 | 0 | | ALGN | 2009-08-04 | 0 | | POT | 2009-08-05 | 0 | | PTR | 2009-08-06 | 0 | | SCHW | 2009-08-06 | 0 | | FDO | 2009-08-07 | 0 | | NBL | 2009-08-07 | 0 | | RRC | 2009-08-07 | 0 | | WAT | 2009-08-08 | 0 | | COCO | 2009-08-08 | 0 | +------+------------+------+ What I want: +------+------------+------+ | sym | FilledDate | numT | +------+------------+------+ | WAT | 2009-08-03 | 1 | | ALGN | 2009-08-04 | 1 | | POT | 2009-08-05 | 1 | | PTR | 2009-08-06 | 1 | | SCHW | 2009-08-06 | 2 | | FDO | 2009-08-07 | 3 | | NBL | 2009-08-07 | 4 | | RRC | 2009-08-07 | 5 | | WAT | 2009-08-08 | 1 | | COCO | 2009-08-08 | 2 | +------+------------+------+ What I need to do is update the TsTradeNum column with the correct values. I have tried to create a function and various queries all failed. Any ideas? Thanks in advance
