• Can't store Data URI to database without stripping + characters

  - by citizencane

  I am trying to grab a reference to images with src's in URI scheme. An example would be the images on google.com/news. if I alert(escape(saveObj.image)); I get something like below: data%3Aimage/jpeg%3Bbase64%2C/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAgGBgcGBQgHBwcJCQgKDBQNDAsLDBkSEw8UHRofHh0aHBwgJC4nICIsIxwcKDcpLDAxNDQ0Hyc5PTgyPC4zNDL/2wBDAQkJCQwLDBgNDRgyIRwhMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjL/wAARCABQAFADASIAAhEBAxEB/8QAHAAAAQUBAQEAAAAAAAAAAAAABgIDBAUHAQAI/8QAPhAAAgECBAMFBgIGCwEAAAAAAQIDBBEABRIhEzFhBkFRcYEUIjKRobFCwRUjJFKC0QcWJSZiY3Jzg7Lw4f/EABoBAAIDAQEAAAAAAAAAAAAAAAMEAAIFBgH/xAAmEQABBAEEAQMFAAAAAAAAAAABAAIDESEEEjFBBRMisVFhcZGh/9oADAMBAAIRAxEAPwAr7L5pD2gyY5JXEtLGAFY/EU2sR1U2+nXF/pZFKuffViGPW5ximQUEz1cNdPNKms6g8TlWBufDcHyxsdLUmqoYqhiWZ1BYtsSe+/ I pass that from the js file and am using django to get that into a mysql table of type utf8_unicode_ci using modelform.save, but when i examine what's in the database, I see: data:image/jpeg;base64,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 nXF/pZFKuffViGPW5ximQUEz1cNdPNKms6g8TlWBufDcHyxsdLUmqoYqhiWZ1BYtsSe The key difference is that in my database all of the '+' characters from the original have been stripped and replaced with spaces.

• Architecture of a secure application that encrypts data in the database.

  - by Przemyslaw Rózycki

  I need to design an application that protects some data in a database against root attack. It means, that even if the aggressor takes control over the machine where data is stored or machine with the application server, he can't read some business critical data from the database. This is a customer's requirement. I'm going to encrypt data with some assymetric algorithm and I need some good ideas, where to store private keys, so that data is secure as well as the application usability was quite comfortable? We can assume, for simplicity, that only one key pair is used.

• Trying to read keyboard input without blocking (Windows, C++)

  - by Adam E

  I'm trying to write a Windows console application (in C++ compiled using g++) that will execute a series of instructions in a loop until finished OR until ctrl-z (or some other keystroke) is pressed. The code I'm currently using to catch it isn't working (otherwise I wouldn't be asking, right?): if(kbhit() && getc(stdin) == 26) //The code to execute when ctrl-z is pressed If I press a key, it is echoed and the application waits until I press Enter to continue on at all. With the value 26, it doesn't execute the intended code. If I use something like 65 for the value to catch, it will reroute execution if I press A then Enter afterward. Is there a way to passively check for input, throwing it out if it's not what I'm looking for or properly reacting when it is what I'm looking for? ..and without having to press Enter afterward?

• Claims-based Authentication: Are strings the essence of claims?

  - by Rising Star

  I've been programming with claims-based authentication for some time now with Windows Identity Foundation. It appears to me that in Windows Identity Foundation, once a user is logged in, the claims are basically strings of information that describe the user. With the old role-based authentication, I could say that a user is or is not a member of a given group, but with claims-based authentication, I can now have strings of information that describe a user. "This user is female". This user was born on "July 6, 1975". "This user logged in using a USB key". Is it the essence of claims-based authentication,that I have strings of information about the user given to the application by the framework?

• 2 (or more) ComboBoxes dependent on each other

  - by Mcad001

  Hi, I have an Organisation entity and a Region entity. An object of type Organisation can have one or more Region objects connected to it, thus I have a foreign key in my Region entity to the Organisation Entity. The Organisation and Region objects are pulled from my database using WCF RIA and entity framework. I want to put the Organisation objects in one ComboBox and the Region objects in another ComboBox, and when selecting an organsation having the ComboBox for Region objects automatically only showing regions that are connected to the selected organisation. Should be pretty basic, but the way I've designed it right now it doesnt work at all. So, any hint to how I can achive this? A simple simple codeexample is much appreciated! (I'm using SL4,WCF RIA MVVM)

• Copy new records from datatable and identify changes in old records

  - by Betite

  Assume there are two tables: Remote_table and My_table. Remote_table has 6 columns: **PROJECT JOB_TYPE MONTH YEAR** HOURS IS_DELETED 134393 70 1 2013 30 0 134393 70 2 2013 50 0 134393 70 3 2013 80 0 134393 70 10 2012 10 0 134393 70 11 2012 0 0 134393 70 12 2012 15 0 My_table is a copy of remote_table. I tried to copy only the new records from the remote_table by this query: SELECT * FROM [remote_DB].[LudanProjectManager].[dbo].Remote_table EXCEPT SELECT * FROM My_table It works OK but I get a duplicate primary key exception when changes have been made on the remote_table on the hours column. Can anyone think of a way to copy only the new records from remote_table and if changes has been made on old records, to identify them and update the my_table to correspond?

• Issue with storing items in session in MVC

  - by Sundeep

  I have a customer page on which user can enter multiple locations for customer. I am using telerik ajax grid to display locations, and when a new location is added, I am adding it to session and returning back to the grid. Finally, when user submits, customer and all locations using customerid as reference key gets inserted. I am clearing the session, when user enters create/edit page and on successful commit or any exception occurs. Problem is when user adds the locations for one user and then opens another tab, to create another user then all locations get cleared for previous user. Coz of session, this issue is occuring. Something of viewstate would be page specific. But for ajax grid actions, viewdata/viewbag is not working. Any thoughts on how to implement this. Thanks in advance.

• How to merge existing row with new data in SQLite?

  - by CSharperWithJava

  I have a database full of simple note data, with columns for title, due date, priority, and details. There is also a _id column PRIMARY KEY int. Say I have a note in the table already with some data filled and the rest null. I also have a set of data that will fill all those fields. Is there a way that I can only write data to the fields that are NULL? I can't overwrite existing data, but I'd like to add data to NULL columns. I know the rowId of the target row. If my target row had rowId of 5, I could do something like this: UPDATE SET duedate='some date', priority='2', details='some text' WHERE _id=5 But that would overwrite all the data in that row, and I don't want to lose any data that might be there. How can I change this statement to avoid writing to non-null fields?

• How can I catch a change event from an HTML text field when a user clicks on a link after editing?

  - by Eric the Red

  Our webapp has a form with fields and values that change depending on values entered. Each time there is a change event on one of the form elements, we use an expensive AJAX call to update other elements on the page. This works great for selects, radio buttons and checkboxes. The issue comes in when a user adds content to a text field, and then clicks a link without taking the focus from the text field. The browser moves to a new page, and the contents of the text field are never saved. Is there an easy way to code around this? The AJAX call is too expensive to call with each key press. Here's an example of my Prototype code at the moment: $$('.productOption input.text').invoke('observe', 'change', saveChangeEvent);

• Sorting NSTableColumn contents

  - by Yahoo

  Hey, I have a problem with sorting NSTableColumn contents. In my NSTableView there are three columns: File, Size, Path. The contents are stored in NSMutableArray. Each object in this array is a NSDictionary containing three keys: file, size and path - value for each is a NSString. In Interface Builder, in each Table Column's attributes I can choose sorting options: Selector: IB entered "compare:" which I think is ok, because I compare NSStrings. Sort Key - and that's the problem I think - I don't know what to enter here. Any clues? If you've got questions about my code, please ask.

• Selecting a sequence NEXTVAL for multiple rows

  - by stringpoet

  I am building a SQL Server job to pull data from SQL Server into an Oracle database through a linked server. The table I need to populate has a sequence for the name ID, which is my primary key. I'm having trouble figuring out a way to do this simply, without some lengthy code. Here's what I have so far for the SELECT portion (some actual names obfuscated): SELECT (SELECT NEXTVAL FROM OPENQUERY(MYSERVER, 'SELECT ORCL.NAME_SEQNO.NEXTVAL FROM DUAL')), psn.BirthDate, psn.FirstName, psn.MiddleName, psn.LastName, c.REGION_CODE FROM Person psn LEFT JOIN MYSERVER..ORCL.COUNTRY c ON c.COUNTRY_CODE = psn.Country MYSERVER is the linked Oracle server, ORCL is obviously the schema. Person is a local table on the SQL Server database where the query is being executed. When I run this query, I get the same exact value for all records for the NEXTVAL. What I need is for it to generate a new value for each returned record. I found this similar question, with its answers, but am unsure how to apply it to my case (if even possible): Query several NEXTVAL from sequence in one satement

• Making bash script to check connectivity and change connection if necessary. Help me improve it?

  - by cypherpunks

  My connection is flaky, however I have a backup one. I made some bash script to check for connectivity and change connection if the present one is dead. Please help me improve them. The scripts almost works, except for not waiting long enough to receive an IP (it cycles to next step in the until loop too quick). Here goes: #!/bin/bash # Invoke this script with paths to your connection specific scripts, for example # ./gotnet.sh ./connection.sh ./connection2.sh until [ -z "$1" ] # Try different connections until we are online... do if eval "ping -c 1 google.com" then echo "we are online!" && break else $1 # Runs (next) connection-script. echo fi shift done echo # Extra line feed. exit 0 And here is an example of the slave scripts: #!/bin/bash ifconfig wlan0 down ifconfig wlan0 up iwconfig wlan0 key 1234567890 iwconfig wlan0 essid example sleep 1 dhclient -1 -nw wlan0 sleep 3 exit 0

• Python sort 2-D list by time string

  - by Mark Kennedy

  How do I sort a multi dimensional list like this based on a time string? The sublists can be of different sizes (i.e. 4 and 5, here) I want to sort by comparing the first time string in each sublist (sublist[-4]) x = (['1513', '08:19PM', '10:21PM', 1, 4], ['1290', '09:45PM', '11:43PM', 1, 4], ['0690', '07:25AM', '09:19AM', 1, 4], ['0201', '08:50AM', '10:50AM', 1, 4], ['1166', '04:35PM', '06:36PM', 1, 4], ['0845', '05:40PM', '07:44PM', 1, 4], ['1267', '07:05PM', '09:07PM', 1, 4], ['1513', '08:19PM', '10:21PM', 1, 4], ['1290', '09:45PM', '11:43PM', 1, 4], ['8772', '0159', '12:33PM', '02:43PM', 1, 5], ['0888', '0570', '09:42PM', '12:20AM', 1, 5], ['2086', '2231', '04:10PM', '06:20PM', 1, 5]) The sorted result would be sortedX = (['0690', '07:25AM', '09:19AM', 1, 4], ['0201', '08:50AM', '10:50AM', 1, 4], ['1166', '04:35PM', '06:36PM', 1, 4], ['0845', '05:40PM', '07:44PM', 1, 4], ['1267', '07:05PM', '09:07PM', 1, 4], ['1513', '08:19PM', '10:21PM', 1, 4], ['1513', '08:19PM', '10:21PM', 1, 4], ['1290', '09:45PM', '11:43PM', 1, 4], ['1290', '09:45PM', '11:43PM', 1, 4], ['8772', '0159', '12:33PM', '02:43PM', 1, 5], ['2086', '2231', '04:10PM', '06:20PM', 1, 5], ['0888', '0570', '09:42PM', '12:20AM', 1, 5]) I tried the following: sortedX = sorted(x, key=lambda k : k[-4]) #k[-4] is the first time string and it works but it doesn't respect the sublist size ordering

• HTML Input on change of value

  - by arik-so

  Hello, I have an input tag. This tag does not have the autocomplete feature turned off, thus, one does not necessarily need to release a key to change the value of this field and focus anotehr one. My question is: how can I detect ANY value changes of this particular field, like e. g. <input onvaluechange="//do following..." /> The JavaScritp attribute onchange does not fire on change of value, only on changes like blur, focus, etc... Thanks in advance!

• C++ associative array with arbitrary types for values

  - by Gerald Kaszuba

  What is the best way to have an associative array with arbitrary value types for each key in C++? Currently my plan is to create a "value" class with member variables of the types I will be expecting. For example: class Value { int iValue; Value(int v) { iValue = v; } std::string sValue; Value(std::string v) { sValue = v; } SomeClass *cValue; Value(SomeClass *v) { cValue = c; } }; std::map<std::string, Value> table; A downside with this is you have to know the type when accessing the "Value". i.e.: table["something"] = Value(5); SomeClass *s = table["something"].cValue; // broken pointer Also the more types that are put in Value, the more bloated the array will be. Any better suggestions?

• Database design efficiency with 1 to many relationships limited 1 to 3

  - by Joe

  This is in mysql, but its a database design issue. If you have a one to many relationship, like a bank customer to bank-accounts, typically you would have the table that records the bank-account information have a foreign key that keeps track of the relationship between account and customer. Now this follows the 3rd normal form thing and is a widely accepted way of doing it. Now lets say that you are going to limit a user to only having 3 accounts. The current database implementation will support this and nothing would need to change. But another way to do this would have 3 coloms in the account table that have the id of the 3 respective accounts in them. By the way this violates 1st normal form of db design. The question is what would be the advantage and disadvantages of having the user account relationship recored in this way over the traditional?

• BeanUtils getPropertyOfMapBean

  - by dx-cp

  Hi, Im wondering if it is possible to get data from property which is map cotaining pairs Key-StringArray (Map) in BeanUtils library. I just simply need to access one of array elements by calling propertyName=string[0]. Current version (1.8.3) does not support indexed properties. If you look into their code you will find in class PropertyUtilsBean in method getPropertyOfMapBean: if (resolver.isIndexed(propertyName) || resolver.isMapped(propertyName)) { throw new IllegalArgumentException( "Indexed or mapped properties are not supported on" + " objects of type Map: " + propertyName); } way too bad:-( Have any of you any tip how to do it somehow differently?

• MaximumErrorCount has now effect

  - by Rob Bowman

  Hi I'm quite new to SSIS - using 2008 version. I have a job that uses a few data flow tasks. On the third one I'm getting a primary key violation on the last row that it needs to insert, but only sometimes! I'd like to ignore this problem for now and let the job continue. I have set the MaximumErrorCount property to 10 for the DataFlowTaks, the SequenceContainer and for the Package but still taks fails and this causes the package to stop. Could anyone please advise how I can get the package to ignore the error? Thanks Rob.

• How to capture the value change of numericUpDown ctrl real-time in .NET?

  I have implement the ValueChanged event, but I found it will be triggered only after change the focus from numericUpDown to other control or by clicking the up/down arrow. Inputting the value in the control will not trigger ValueChanged event. What I did now is adding an KeyDown event and judge if the input value is numeric (can not include SHIFT/CTRL/ALT key); but there is another case need to be involved: the user can paste value into the numericUpDown ctrl What I need is : When I was typing numeric value (only numeric) in the numericUpDown ctrl, it will known the content has been changed; When pasted a numeric value into the ctrl, it also kowns the content changed

• How to speed up saving data to database over the internet?

  - by robert_d

  I am using C#, Entity Framework and SQL Server 2008 Express. I am connected to the database over the internet. What is the best method to speed up saving/updating data to database? It takes 87 seconds to save 180 records to the database. It takes only 3.5 seconds to save the same number of records to local (on the same machine) SQL Server. For every record that I save/update I check if record with this primary key exists in the database, if it doesn't exists I simply save it, if it exists I update it using ObjectContext.ApplyCurrentValues(entitySetName, currentEntity) method.

• getting the value of a filter at an arbitrary time

  - by Andiih

  Context: I'm trying to improve the values returned by the iPhone CLLocationManager, although this is a more generally applicable problem. The key is that CLLocationManger returns data on current velocity as and when it feels like it, rather than at a fixed sample rate. I'd like to use a feedback equation to improve accuracy v=(k*v)+(1-k)*currentVelocity where currentVelocity is the speed returned by didUpdateToLocation:fromLocation: and v is the output velocity (and also used for the feedback element). Because of the "as and when" nature of didUpdateToLocation:fromLocation: I could calculate the time interval since it was last called, and do something like for (i=0;i<timeintervalsincelastcalled;i++) v=(k*v)+(1-k)*currentVelocity which would work, but is wasteful of cycles. Especially as I probably want timeintervalsincelastcalled to be measured as 10ths of a second. Is there a way to solve this without the loop ? i.e. rework (integrate?) the formula so I put an interval into the equation and get the same answer as I would have by iteration ?
