• EXCEL import to sql returning NULL for decimals when in VARCHAR data type

  - by Daniel

  Hi, I am working on a peice of software which has expodentially grown over the last few years and the database needs to be regularly updated. Customers are providing us with data now on large spreadsheets which we format and will start importing into the database. I am using the Import and Export Data (32-bit) Wizard. One column in the database contains values like '1.1.1.2' etc and i am importing them in as a Varchar as that is the data type in the database. However, for values like '8.5', 'NULL' is getting imported insead. It only occurs when there is one decimal point. Is this a formatting error with excel or is it the wrong datatype?

• Passing data between Castle Windsor's Interceptors

  - by Nhím H? Báo

  I'm adopting Castle Windsor for my WCF project and feel really amazed about this. However, I'm having a scenario that I don't really know if Castle Windsor supports. For example I have the following chained Interceptors Interceptor 1 > Interceptor 2 > Interceptor 3 > Interceptor 4 > Real method Interceptor 1 returns some data and I want that to be available in Interceptor 2 Interceptor 2 in turn does it work and returns the data that I want to make avaialbe in the 3,4, interceptor. The real case scenario is that we're having a WCF service, Interceptor 1 will parse the request header into a Header object(username, password, etc.). The latter interceptors and real method will ultilize this Header object. I know that I can use Session variable to transport data, but is it a built-in, more elegant, more reliable way to handle this?

• Best place to store large amounts of session data

  - by audiopleb

  I'm building an application that needs to store and re-use large amounts of data per session. So for example, the user selects a large list of list items (say 2000 or significantly more) which have a numeric value as their key then they save that selection and go off to another page, do something else and then come back to the original page and need to load their selections into that page. What is the quickest and most efficient way of storing and reusing that data? In a text file saved with the session id? In a temp db table? In the session data itself (db sessions so size isn't a limit) using a serialised string or using gzcompress or gzencode? Any advice or insight would be great! Thank you!!!!

• Dynamically adding data to a UITableView

  - by tableview

  Hey guys! I'm new to Objective C and I need a little help. I've created a UITableView in a UIViewController. I'd like to know how to populate my UITableView dynamically. The data is a bunch of labels that I've stored in a NSMutableArray. So each row displays the contents of the array. Once the array is reloaded with fresh data, the second row will then keep displaying the data as it is added to the array. Thanks in advance for any help!

• Consolidating data in SharePoint from different sites based on variable site naming

  - by Mughrabi

  Hi, am working on a project where I want to pull data from different lists in SharePoint and have these data imported into a single list. The list has the same attribute everywhere; it is located in different sites. I have a list which contains all the site names and URL to those sites. The idea is to read from this list all the site names and then go to each one of those sites and try and pull the information from the list under that particular site, in synchronies matter. Data that are pulled from last week’s process do not need to be pulled again. Can someone guide me in explaining what would be the best way to doing this solution? Am using SharePoint 2007

• CoreData leak when reading a property

  - by Kamchatka

  Hello, I have the following code in a loop iterating over the different document objects: NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init]; [document primitiveValueForKey:@"data"]; [data writeToFile:filename atomically:NO]; [document.managedObjectContext refreshObject:document mergeChanges:NO]; [pool release]; The "data" property is a large blob (a 1MB image). And as I monitor the memory with the Allocation Instrument memory usage is increasing. I cannot find where the leak is coming from and how to remove it. Thanks!

• Grails design for domain class initialization from static data

  - by Allison Eer

  I have some data, stateNames, to instantiate an instance of the object Country. Right now, I will only have one Country but stateNames for each country should be different. What is the best way to instantiate the instance of Country with my data? I am new to grails and would appreciate any "best practices" or common designs. One solution I can think of is to use BootStrap to save the unitedStates instance of Country to the database. What are the cons of this approach? Another solution would be to save the data in a file (in xml?) under web-app folder. If I did this approach, should the unitedStates instance of Country be instantiated by a controller?

• Python: Data Object or class

  - by arg20

  I enjoy all the python libraries for scraping websites and I am experimenting with BeautifulSoup and IMDB just for fun. As I come from Java, I have some Java-practices incorporated into my programming styles. I am trying to get the info of a certain movie, I can either create a Movie class or just use a dictionary with keys for the attributes. My question is, should I just use dictionaries when a class will only contain data and perhaps almost no behaviour? In other languages creating a type will help you enforce certain restrictions and because of type checks the IDE will help you program, this is not always the case in python, so what should I do? Should I resort to creating a class only when there's both, behaviour and data? Or create a movie class even though it'll probably be just a data container? This all depends on your model, in this particular case either one is fine but I'm wondering about what's a good practice.

• Creating a virtual, data-driven section of a Wordpress-powered site

  - by lgomez

  Hello all, I want to create a plugin for wordpress to automatically serve pages containing data pulled from a provider's API. The API returns one or more records containing data for that record and I simply want to have the plugin intercept the request, call the API with parameters pulled from the request URI and display the data using a template that I can either let them upload to the server or let them copy and paste into the plugins admin settings. For example, I may want one of my wordpress installations to show products pulled from such an API under the url "example.com/products". The plugin would catch that request, extract the variables from the URL, call the API and render the template with the returned results. I'd like to avoid requiring editing the .htaccess file like some caching plugins do. Some of the admins of these pages won't know how to do that or simply won't have access to the .htaccess file. Thanks!

• Adding new "columns" to csv data file in Tcl

  - by George

  Hi All, I am dealing with a "large" measurement data, approximately 30K key-value pairs. The measurements have number of iterations. After each iteration a datafile (non-csv) with 30K kay-value pairs is created. I want to somehow creata a csv file of form: Key1,value of iteration1,value of iteration2,... Key2,value of iteration1,value of iteration2,... Key2,value of iteration1,value of iteration2,... ... Now, I was wondering about efficient way of adding each iteration mesurement data as a columns to csv file in Tcl. So, far it seems that in either case I will need to load whole csv file into some variable(array/list) and work on each element by adding new measurement data. This seems somewhat inefficient. Is there another way, perhaps?

• Pyserial : How to send data to drive SIPO

  - by bino oetomo

  Dear All .. I'm learning to drive a stepper motor with Python. It's hard now to find a PC with paralel port. So My plan is using a USB-Serial .. and a SIPO (serial in parallel out) shift register circuit. As you know with this circuit we need to send a binary data in series and this data will be stored in it's register. Next we need to send another one pulse to make it shift the data out to the out-port. How to do it using pyserial ? Sincerely -bino-

• Using a class with const data members in a vector

  - by Max

  Given a class like this: class Foo { const int a; }; Is it possible to put that class in a vector? When I try, my compiler tells me it can't use the default assignment operator. I try to write my own, but googling around tells me that it's impossible to write an assignment operator for a class with const data members. One post I found said that "if you made [the data member] const that means you don't want assignment to happen in the first place." This makes sense. I've written a class with const data members, and I never intended on using assignment on it, but apparently I need assignment to put it in a vector. Is there a way around this that still preserves const-correctness?

• Proper way to build a data Repository

  - by rockinthesixstring

  I'm working on using the Repository methodology in my App and I have a very fundamental question. When I build my Model, I have a Data.dbml file and then I'm putting my Repositories in the same folder with it.... IE: Data.dbml IUserRepository.cs UserRepository.cs My question is simple. Is it better to build the folder structure like that above, or is it ok to simply put my Interface in with the UserRepository.cs? Data.dbml UserRepository.cs              which contains both the interface and the class

• Linq to SQL and Realtime Data

  - by Jeremy

  I have an application that needs to constantly (every 50ms), call to an MVC action, and pickup/drop off data. I am using Linq to SQL and MVC because of how simple they are to implement, and I know that they aren't perfect when it comes to performance, but it works relatively well, but the best speed I can get with my current approach is 200ms (without requests overlapping). Each call to the site will create a new instance of the datacontext, query/insert it and return that data. Is there a way to have the datacontext static, but submitchanges say every 5 seconds, so that i am pretty much hitting an in-memory version of the data?

• get data from gridview without querying database

  - by frank2009

  Hi there I am new at this so please bear with me... I have managed to get the following code to work...so when I click on the "select" link in each row of the gridview, the data is transfered to other label/textbox on the webpage. So far so good, the thing is that everytime I click on select...it goes and checks on the database for the data and there is a delay of a few seconds... I was hoping that the data, since it is already visible on the gridrows, is simply "picked up" and used on other labels/textboxes...without requerying the database. Is this possible ? Thanks in advance Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Label1.Text = GridView2.SelectedRow.Cells(8).Text Label2.Text = GridView2.SelectedRow.Cells(9).Text TextBox1.Text = GridView2.SelectedRow.Cells(7).Text End Sub

• store data in asp.net pages (Not Sessions)

  - by ARB

  I am creating 4 asp.net pages. first three pages have 'CONTINUE' button and last page has 'SUBMIT' button. I am not allowed to use Sessions to store first three pages data. and i need to use 'BACK' button on last three pages. when i click 'BACK' button i need to maintain the previous page data entered by user. As my pages do some postbacks, i cannot use javascript.history function. My restrictions are: As the application is served from a web farm, a session object cannot be used. However, for the purpose of this excersise, consider session object as database-like persistent space where you can store your data. your code should show an easy way to switch to a different persistent space. What is databse like persistent space and how to write a code to switch to different persistent space?... Please give me some idea on how to proceed.... Thank you

• How to efficiently deal with a large amount of HTML5 canvas pixel data over websockets

  - by user730569

  Using imageData = context.getImageData(0, 0, width, height); JSON.stringify(imageData.data); I grab the pixel data, convert it to a string, and then send it over the wire via websockets. However, this string can be pretty large, depending on the size of the canvas object. I tried using the compression technique found here: JavaScript implementation of Gzip but socket.io throws the error Websocket message contains invalid character(s). Is there an effective way to compress this data so that it can be sent over websockets?

• Is it possible to get RSA private key knowing public key and set of "original data=>encrypted data"

  - by Riz

  Hi, I work on apllication which allows plugins to access different set of functionality, every plugin provides "initialization string" which sets level of access to different features. Developers send me this strings, and I encrypt them using my 1024 bit RSA private key and send encoded data back. When started, my application decodes encoded data(encoded initialisation string) using built-in public key and if "decoded data != initialization string" it fails to start. So, is it possible to use a database of "initialization string" = "encoded initialization string"(extracted from other plugins) to crack my private key, or make it possible to bruteforce it in reasonable time?

• Django: Data corrupted after loading? (possible programmer error)

  - by Rosarch

  I may be loading data the wrong way. excerpt of data.json: { "pk": "1", "model": "myapp.Course", "fields": { "name": "Introduction to Web Design", "requiredFor": [9], "offeringSchool": 1, "pre_reqs": [], "offeredIn": [1, 5, 9] } }, I run python manage.py loaddata -v2 data: Installed 36 object(s) from 1 fixture(s) Then, I go to check the above object using the Django shell: >>> info = Course.objects.filter(id=1) >>> info.get().pre_reqs.all() [<Course: Intermediate Web Programming>] # WRONG! There should be no pre-reqs >>> from django.core import serializers >>> serializers.serialize("json", info) '[{"pk": 1, "model": "Apollo.course", "fields": {"pre_reqs": [11], "offeredIn": [1, 5, 9], "offeringSchool": 1, "name": "Introduction to Web Design", "requiredFor": [9]}}]' The serialized output of the model is not the same as the input that was given to loaddata. The output has a non-empty pre_req list, whereas the input's pre_reqs field is empty. What am I doing wrong?

• what changes when your input is giga/terabyte sized?

  - by Wang

  I just took my first baby step today into real scientific computing today when I was shown a data set where the smallest file is 48000 fields by 1600 rows (haplotypes for several people, for chromosome 22). And this is considered tiny. I write Python, so I've spent the last few hours reading about HDF5, and Numpy, and PyTable, but I still feel like I'm not really grokking what a terabyte-sized data set actually means for me as a programmer. For example, someone pointed out that with larger data sets, it becomes impossible to read the whole thing into memory, not because the machine has insufficient RAM, but because the architecture has insufficient address space! It blew my mind. What other assumptions have I been relying in the classroom that just don't work with input this big? What kinds of things do I need to start doing or thinking about differently? (This doesn't have to be Python specific.)

• Declaring a data type dynamically in C++

  - by Bobby

  I want to be able to do the following: I have an array of strings that contain data types: string DataTypeValues[20] = {"char", "unsigned char", "short", "int"}; Then later, I would like to create a variable of one of the data types at runtime. I won't know at compile time what the correct data type should be. So for example, if at runtime I determined a variable x needed to be of type int: DataTypeValues[3] x = 100; Obviously this won't work, so how could I do something like this?
