  • java RSA Multiple Encryption

    - by user1763730
    I encrypt my message with a symmetric key and the symmetric key itself has to be further encrypted with different RSA public keys. When I tried to implement the above I got the following error: javax.crypto.IllegalBlockSizeException: The input was invalid: Invalid input length. at com.rsa.shareCrypto.j.hD.engineDoFinal(Unknown Source) at javax.crypto.Cipher.doFinal(Cipher.java:2087) at wrap1.main(wrap1.java:69) Is there a way to solve this problem ?

  • multiple regionDidChangeAnimated calls - what gives?

    - by mvexel
    I have a MKMapView inside a UITableView as a custom cell (don't ask ;) - don't know if it matters really), for which I register a regionDidChangeAnimated delegate method. This method gets called three times when the UITableView is loaded - once with the actual region and then two more times with a region that is way off. In the simulator, I consistently get a region with center (+37.43997405, -97.03125000). On the device, it seems to depend on the location reported by the location manager, which initializes the map view. Why am I getting three regionDidChangeAnimated calls? And why are the center coordinates for the last two of them off? This is the code I use to get the center coordinates: - (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated { CLLocation *l = [[CLLocation alloc] initWithLatitude:self.mapView.centerCoordinate.latitude longitude:self.mapView.centerCoordinate.longitude]; (....)

  • MULTIPLE CRITERIA TABLE JOIN

    - by user1447203
    I have a table listing clothing items (shirt, trousers, etc) named . Each item is identified with a unique CLOTHING.CLOTHING_ID. So a blue shirt is 01, a flowery shirt is 12 and jeans are 07 say. I have a second table identifying outfits with a column for shirts, for trousers, shoes etc. For example Outfit 1: shirt 01, trousers 07 (i.e. blue shirt with jeans) Outfit 2: shirt 12, trousers 07 (so flowery shirt with jeans). This table is named and each outfit is unique with OUTFIT_LIST.OUTFIT_ID. I want to produce a select statement that will list each outfit's contents, i.e. find the clothing specified in Outfit 1. Any help would be very much appreciated, and apologies in advance if I am missing a very simple solution. I have been playing with JOINS of all descriptions and CONCATS and so on with now luck - I am very new to this. Thanks.

  • multiple threads writting to a same socket problem

    - by alex
    Hi: My program uses sockets for inter-process communication. There is one server listening on a socket port(B) on localhost waiting for a list of TCP clients to connect. And on the other end of the server is another a socket(A) that sends out data to internet. The server is designed to take everything the TCP clients send him and forward to a server on the internet. My question is if two of the TCP clients happened to send data at the same time, is this going to be a problem for the server's outgoing socket(A)? Thanks

  • Tallying records using annotate() not working as should.

    - by 47
    I have two classes: Vehicle and Issues....a Vehicle object can have several issues recorded in the Issues class. What I want to do is to have a list of all issues, with each vehicle appearing only once and the total number of issues shown, plus other details....clicking on the record will then take the user to another page with all those issues for a selected vehicle shown in detail now. I tried this out using annotate, but I could only access the count and vehicle foreign key, but none of the other fields in the Vehicle class. class Issues(models.Model): vehicle = models.ForeignKey(Vehicle) description = models.CharField('Issue Description', max_length=30,) type = models.CharField(max_length=10, default='Other') status = models.CharField(max_length=12, default='Pending') priority = models.IntegerField(default='8', editable=False) date_time_added = models.DateTimeField(default=datetime.today, editable=False) last_updated = models.DateTimeField(default=datetime.today, editable=False) def __unicode__(self): return self.description The code I was using to annotate is: issues = Issues.objects.all().values('vehicle').annotate(count=Count('id')) What could be the problem?

  • Mysql multiple row count?

    - by Steven
    Hello, I have a database full of rows like id,action,date 2,2,2010-03-01 3,2,2010-03-01 4,3,2010-03-01 5,3,2010-03-01 6,4,2010-02-01 7,4,2010-02-01 And I want to select all the count all the 2's and all the 3's and all the 4's. But I don't want to have to do 3 different SELECT COUNT() commands, is there a way to do this in a single command? Note, I want to display this as something like Action 2 = 2 Action 3 = 2 Action 4 = 2 (etc etc). And I will also need to specific a date (so it only counts all the 2,3,4,etc for dates between 2010-02-03 and 2010-03-01 for example)

  • Database design to hold multiple iteration measurements

    - by Valder
    Hi All. I am new to sqlite and SQL in general. I am keen to switch from flat-files to sqlite for holding some measurement information. I need a tip on how to better layout the database, since I have zero experience with this. I have a ~10000 unique statistic counters that are collected before and after each test iteration. Max number of iterations are 10, though it could be less. I was thinking the following: CREATE TABLE stat_names(stat_id, stat_name); CREATE TABLE stats_per_iteration(stat_id, before_iter_1, after_iter_1, before_iter_2, after_iter_2, ...); stat_names table would hold mapping of a full counter to a uniq stat_id. stats_per_iteration table would hold mesurement data 1 + 10 * 2 columns. stat_names.stat_id = stats_per_iteration.stat_id OR maybe I should have a separate table for each iteration? Which would results in 1 + 10 tables in database. Thanks!

  • EF 4 Query - Issue with Multiple Parameters

    - by Brian
    Hello, A trick to avoiding filtering by nullable parameters in SQL was something like the following: select * from customers where (@CustomerName is null or CustomerName = @CustomerName) This worked well for me in LINQ to SQL: string customerName = "XYZ"; var results = (from c in ctx.Customers where (customerName == null || (customerName != null && c.CustomerName == customerName)) select c); But that above query, when in ADO.NET EF, doesn't work for me; it should filter by customer name because it exists, but it doesn't. Instead, it's querying all the customer records. Now, this is a simplified example, because I have many fields that I'm utilizing this kind of logic with. But it never actually filters, queries all the records, and causes a timeout exception. But the wierd thing is another query does something similarly, with no issues. Any ideas why? Seems like a bug to me, or is there a workaround for this? I've since switched to extension methods which works. Thanks.

  • Improve disk read performance (multiple files) with threading

    - by pablo
    I need to find a method to read a big number of small files (about 300k files) as fast as possible. Reading them sequentially using FileStream and reading the entire file in a single call takes between 170 and 208 seconds (you know, you re-run, disk cache plays its role and time varies). Then I tried using PInvoke with CreateFile/ReadFile and using FILE_FLAG_SEQUENTIAL_SCAN, but I didn't appreciate any changes. I tried with several threads (divide the big set in chunks and have every thread reading its part) and this way I was able to improve speed just a little bit (not even a 5% with every new thread up to 4). Any ideas on how to find the most effective way to do this?

  • Multiple column foreign key contraints

    - by eugene4968
    I want to setup table constraints for the following scenario and I’m not sure how to do it or if it’s even possible in SQL Server 2005. I have three tables A,B,C. C is a child of B. B will have a optional foreign key(may be null) referencing A. For performance reasons I also want table C to have the same foreign key reference to table A. The constraint on table C should be that C must reference its parent (B) and also have the same foreign key reference to A as its parent. Anyone have any thoughts on how to do this?

  • Stored procedure for selecting multiple records

    - by padmavathi
    I need to select records say 2000 from a table with a matching timestamp from c# .net code. Eg: SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME='Item1' and TimeStamp='2010-04-26 17:15:05.667' The above query has to execute for 2000 items more for the same timestamp. for this we can use SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME in ('Item1','Item2','Item3','Item4',......) AND TimeStamp='2010-04-26 17:15:05.667' from SQL Server Management Studio. I have tried appending all Item names to one string variable and giving it as a parameter to the stored procedure,but it resulted into a wrong concatenation. How can I do this as a stored procedure executing from the .net code? Can anyone suggest me/correct me in doing this? Thanks & Regards Padma

  • WPF problem modify style of images in multiple Button Templates

    - by user556415
    I'm trying to create a control panel for a video camera, the panel has buttons for up, down, left and right etc. Each camera function up, down, left and right is represented by three images (see code below) for the left side, middle and right side. The control panel is circular so the corner images kind of overlap (its complicated to explain this without a visual). When I click on up for example I have to hide the initial three images (leftside, middle and right side) and display another three images for left , middle and right that indicate that the button is pressed. I am achieving this by having a grid inside a button template. The problem I have is that for the corner images for the control there are really four images that represent this. For example for the top left corner the four images would be represent 1. Top not clicked. 2. Top Clicked and 3. Left Not clicked and 4. Left Clicked. My problem is if I need to make the images contained within the Top button have precedence when the top control is clicked or the images in the left button have precedence when the left button is clicked. So it's like I want to modify the left button's image visible property when the top button is clicked and vise versa. This is really difficult to explain so I apologize if it makes little sense but I can email the source code on request if anyone is interested in my predicament. <Grid> <Canvas> <!--<StackPanel>-->

  • how to create multiple tcp connections between server and client

    - by lowcosthighperformance
    I am new in Unix/Linux networking programming, so I have written server-client program in below.In this code there is one socket between client and server, client requests to server, then server responses from 1 to 100 numbers to client. So my question is how can we do this process with 3 socket( tcp connection) without using thread? ( e.g. First socket runs then second runs then third runs then first again .. ) Do you have any suggestion? Thank you client.c int main() { int sock; struct sockaddr_in sa; int ret; char buf[1024]; int x; sock = socket (AF_INET, SOCK_STREAM, 0); bzero (&sa, sizeof(sa)); sa.sin_family = AF_INET; sa.sin_port = htons(SERVER_PORT); inet_pton (AF_INET, SERVER_IP, &sa.sin_addr); ret = connect (sock, (const struct sockaddr *) &sa,sizeof (sa)); if (ret != 0) { printf ("connect failed\n"); exit (0); } x = 0; while (x != -1) { read (sock, buf , sizeof(int)); x = ntohl(*((int *)buf)); if (x != -1) printf ("int rcvd = %d\n", x); } close (sock); exit (0); } server.c int main() { int list_sock; int conn_sock; struct sockaddr_in sa, ca; socklen_t ca_len; char buf[1024]; int i; char ipaddrstr[IPSTRLEN]; list_sock = socket (AF_INET, SOCK_STREAM, 0); bzero (&sa, sizeof(sa)); sa.sin_family = AF_INET; sa.sin_addr.s_addr = htonl(INADDR_ANY); sa.sin_port = htons(SERVER_PORT); bind (list_sock,(struct sockaddr *) &sa,sizeof(sa)); listen (list_sock, 5); while (1){ bzero (&ca, sizeof(ca)); ca_len = sizeof(ca); // important to initialize conn_sock = accept (list_sock,(struct sockaddr *) &ca,&ca_len); printf ("connection from: ip=%s port=%d \n",inet_ntop(AF_INET, &(ca.sin_addr), ipaddrstr, IPSTRLEN),ntohs(ca.sin_port)); for (i=0; i<100; ++i){ *((int *)buf) = htonl(i+20); // we using converting to network byte order write (conn_sock, buf, sizeof(int)); } * ((int *)buf) = htonl(-1); write (conn_sock, buf, sizeof(int)); close (conn_sock); printf ("server closed connection to client\n"); } }

  • Multiple HTTP request - Rails

    - by bradleyg
    My application checks a number of domains to see if they are valid (approx 100). I have the following code to check a single domain: def self.test_url uri, limit = 10 if limit == 0 return get_error_messages("001") end begin url = URI.parse(uri) response = Net::HTTP.start(url.host, url.port).request_head('/') rescue SocketError => e return get_error_messages("002") end case response when Net::HTTPRedirection then test_url(response['location'], limit - 1) else return get_error_messages(response.code) end end The code checks for the response code while taking into account redirects. This works fine. The only problem I have is when I put this in a loop I want it to run in parallel. So I don't have to wait for domain 1 to respond before I can request domain 2. I have managed this in PHP using curl_multi to run the requests in parallel. Is there a similar thing I can do in Rails?

  • How to write a CASE WHEN statement with multiple DATEDIFF variables

    - by Anne C
    I need to calculate the difference between two dates (facility_start_date, facility_end_date) for a report in Reporting Services in SQL 2005. If the facility_end_date is null then it needs to use the report parameter @EndDate in the calculation. However if the facility_end_date is greater than the parameter @EndDate, then it also needs to use the paramenter @EndDate. The code below works fine except that if the facility_end_date is greater than the parameter @EndDate it is still calculating between the facility_start_date and facility_end_date, rather than between the facility_start_date and @EndDate. Any help would be appreciated. CASE WHEN facility_start_date > facility_end_date THEN NULL WHEN DATEPART(day , facility_start_date) > DATEPART(day , facility_end_date) THEN DATEDIFF(d , facility_start_date , ISNULL(facility_end_date , @EndDate)) - 1 WHEN DATEPART(day , .facility_end_date) > DATEPART(day , @EndDate) THEN DATEDIFF(d , facility_start_date , @EndDate) - 1 ELSE DATEDIFF(d , facility_start_date , ISNULL facility_end_date , @EndDate)) END
