  • PostgeSQL: Arrays Data Type with PHP

    - by ArchJ
    I'm working on PostgeSQL with PHP and I know that PosrgeSQL allow columns of a table to be defined as arrays. So let's say I have a table like this: CREATE TABLE sal_emp ( a text ARRAY, b text ARRAY, c text ARRAY, ); These are my arrays: $a = array(aa,bb,cc); $b = array(dd,dd,aa); $c = array(bb,ff,ee); and I want to insert them into respective column each like this: a | b | c -----------+------------+------------ {aa,bb,cc} | {dd,dd,aa} | {bb,ff,ee} Can I insert it this way? $a = implode(',', $a); $b = implode(',', $b); $c = implode(',', $c); $a = array('a' => $a, 'b' => $b, 'c' => $c); pg_insert($dbconn, 'table', $a); Or is there a better way to achieve the same result?

  • Extracting data from Visual FoxPro databases

    - by whitequark
    I just got some 20Gb of data in a Visual FoxPro database with a custom frontend probably written in the same framework, and need to extract that data in any well-known format. I don't know anything about VFP in particular, but as it is SQL, there should be a way of opening an SQL console, or maybe an vfpdump utility. How can I do that? Everything I have now are a bunch of obscure binary files and a frontend executable.

  • nullable type and a ReSharper warning

    - by Sarah Vessels
    I have the following code: private static LogLevel? _logLevel = null; public static LogLevel LogLevel { get { if (!_logLevel.HasValue) { _logLevel = readLogLevelFromFile(); } return _logLevel.Value; } } private static LogLevel readLogLevelFromFile() { ... } I get a ReSharper warning on the return statement about a possible System.InvalidOperationException and it suggests I check _logLevel to see if it is null first. However, readLogLevelFromFile returns LogLevel, not LogLevel?, so there is no way the return statement could be reached when _logLevel is null. Is this just an oversight by ReSharper, or am I missing something?

  • Encrypt Data Prior to Upload

    - by TheW
    I'm looking to store some data online but I want to encrypt the files first. Since I understand that sFTP will only encrypt the transmission of the data, I'm wondering what program others use to encrypt their files prior to sFTPing them to a backup server. Thanks.

  • Is there such a thing as a C# style extension method in C++ ?

    - by Gary Willoughby
    I'm currently learning C++ and i run into the simple problem of converting an int to a string. I've worked around it using: string IntToString(int Number) { stringstream Stream; Stream << Number; return Stream.str(); } but though it would be more elegant to use something like: int x = 5; string y = x.toString(); but how do i add the toString() method to a built in type? or am i missing something totally fundamental?

  • Object or primitive type

    - by John
    Hi, Can someone explain to me the usage of Integer, Boolean etc in place of their primitive types in JAVA? I can't seem to grasp the advantages their are providing. They seem to create unnecessary problems of handling null values. Thanks!

  • Checking type sizes in C with macros.

    - by Seisatsu
    I'm writing a program that needs to have unsigned types with definite sizes. I need a uint8, uint16, uint32, and uint64, and I need them defined in types.h, in a way that they will always be defined correctly regardless of platform. My question is, how can I check the sizes of different types on each platform using preprocessor macros, so that I can define my custom types correctly in the types.h header?

  • Hyper-V Ubuntu Networking Problems Copying Large Amounts of Data

    - by Anonymous
    I am trying to copy a large amount (about 50 GB) of data over my network from a Hyper-V-hosted virtual machine running Ubuntu 11.04 (Natty Narwhal) to another (non-virtual) Ubuntu host that I plan to use for testing upgrades to one of our web applications. The problem I am having is with the virtual machine, which I shall refer to in what follows as "source.host". This machine is running 64-bit Ubuntu Server with the 2.6.38-8-server kernel and the Microsoft Linux Integration Components for Hyper-V kernel modules (hv_utils, hv_timesource, hv_netvsc, hv_blkvsc, hv_storvsc, and hv_vmbus) loaded. It uses a Hyper-V "synthetic network adapter" for its networking interface. To do the copy, I log on to the machine with the data and run the following commands (Call the remote machine "destination.host".): $ cd /path/to/data $ tar -cvf - datafolder/ | ssh [email protected] "cat > ~/data.tar" This runs for a while and then suddenly stops after transferring somewhere from 2-6 GB. The terminal on the source.host machine displays a Write failed: broken pipe error. The odd part is this: after this occurs, the "source.host" machine is no longer able to talk to the rest of the network. I cannot ping any other hosts on the network from the "source.host" machine, and I cannot ping the "source.host" machine from any other host on the network. I am equally unable to access the any of the web services hosted on "source.host". Running ifconfig on "source.host" shows the network adapter to be up and running as usual with the correct IP address and everything. I tried restarting the networking service with $ /etc/init.d/networking restart but the problem does not go away. Restarting the machine makes it capable of talking to the network again -- it can ping and be pinged by other hosts, and the web services are also accessible and usable as normal -- but attempting the copy operation again results in the same failure, requiring another restart. As an experiment, I tried replacing the tar -- ssh pipeline above with a straight scp: $ scp -r datafolder/ [email protected]:~ but to no avail Thinking that the issue might have to do with the kernel packet-send buffers filling up, I tried increasing the buffer size to 12 MB (up from the 128 KB default) with # echo 12582911 > /proc/sys/net/core/wmem_max but this also had no effect. I'm guessing at this point that it might be a problem with the Microsoft synthetic network driver, but I don't really know. Does anyone have any suggestions? Thank you very much in advance!

  • basic json > struct question

    - by danwoods
    I'm working with twitter's api, trying to get the json data from http://search.twitter.com/trends/current.json which looks like: {"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} My structs look like: type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } and then I parse the JSON into a variable of type Trending. I'm very new to JSON so my main concern is making sure I've have the data structure correctly setup to hold the returned json data. I'm writing this in 'Go' for a project for school. (This is not part of a particular assignment, just something I'm demo-ing for a presentation on the language)

  • Dynamically creating subviews of similar type

    - by Akki
    My code for above view is: -(void)viewWillAppear:(BOOL)animated{ float yh = 0; while (yh<200) { //UIView CGRect myFrame = CGRectMake(0, yh, 320, 30); UIView *myFirstView = [[UIView alloc] initWithFrame:myFrame]; myFirstView.backgroundColor = [UIColor orangeColor]; //IUILabel in UIView CGRect mylblFrame = CGRectMake(5, yh, 60, 15); UILabel *lblsize = [[UILabel alloc] initWithFrame:mylblFrame]; lblsize.text = @"Hello"; [myFirstView addSubview:lblsize]; CGRect mylbl_hi = CGRectMake(80, yh, 60, 15); UILabel *lbl_hi = [[UILabel alloc] initWithFrame:mylbl_hi]; lbl_hi.text = @"Hii"; [myFirstView addSubview:lbl_hi]; [self.view addSubview:myFirstView]; [lbl_hi release]; [lblsize release]; [myFirstView release]; yh=yh+40; } [super viewWillAppear:YES]; } I can't understand reason of it being like this...i wanted labels to be attached with my subviews of orange color...this may be odd day for me to understand what's wrong with my code...if any of you can tell me where i ma doing wrong would be great to me.

  • SQLite SQLite column can't be updated to any value but zero (real type)

    - by user1065320
    Hi I'm trying to create a three fields table (date,text,real), I can insert and update the first two fields but can't set or update the last one. createSQL = @"CREATE TABLE IF NOT EXISTS ACTIVITIES (MYDATE DATETIME PRIMARY KEY, ACTIVITY TEXT , LENGTH REAL);"; try to insert char *update = "INSERT OR REPLACE INTO ACTIVITIES (MYDATE, ACTIVITY , LENGTH) VALUES (?, ? ,?);"; sqlite3_stmt *stmt; if (sqlite3_prepare_v2(database, update , -1, &stmt, nil) == SQLITE_OK) { sqlite3_bind_double(stmt, 1, valueToWrite); sqlite3_bind_text(stmt, 2, [task UTF8String], -1, NULL); sqlite3_bind_double(stmt, 3, 1.5); } if (sqlite3_step(stmt) != SQLITE_DONE) { NSAssert1(0, @"Error updating table: %s", errorMsg); } sqlite3_finalize(stmt); sqlite3_close(database); The first two values are updated but the last one remains 0 even if I'm writing a value like 1.5 or put a double variable with a different value Thanks

  • Load balancers, multiple data centers and url based routing

    - by kunkunur
    There is one data center - dc1. There is a business need to setup another data center - dc2 in another geography and there might be more in the future say dc3. Within the data center dc1: There are two web servers say WS1 and WS2. These two webservers do not share anything currently. There isnt any necessity foreseen to have more webservers within each dc. dc1 also has a local load balancer which has been setup with session stickiness. So if a user say u1 lands on dc1 and if the load balancer decides to route his first request to WS1 then from there on all u1's requests will get routed to WS1. Local load balancer and webservers are invisible to the user. Local load balancer listens to the traffic on a virtual ip which is assigned to the virtual cluster of webservers ws1 and ws2. Virtual ip is the ip to which the host name is resolved to in the DNS. There are no client specific subdomains as of now instead there is a client specific url(context). ex: www.example.com/client1 and www.example.com/client2. Given above when dc2 is onboarded I want to route the traffic between dc1 and dc2 based on the client. The options that I have found so far are. Have client specific subdomains e.g. client1.example.com and client2.example.com and assign each of them with the virtual ip of the data center to which I want to route them. or Assign www.example.com and www1.example.com to first dc i.e. dc1 and assign www2.example.com to dc2. All requests will first get routed to dc1 where WS1 and WS2 will redirect the user to www1.example.com or www2.example.com based on whether the url ends with /client1 or /client2. I need help in the following If I setup a global load balancer between dc1 and dc2 do I have any alternative solutions. That is, can a global load balancer route the traffic based on the url ? Are there drawbacks to subdomain based solutions compared to www1 solution? With www1 solution I am worried that it creates a dependency on dc1 atleast for the first request and the user will see that he is getting redirected to a different url.

  • Template deduction based on return type?

    - by Marlon
    I'd like to be able to use template deduction to achieve the following: GCPtr<A> ptr1 = GC::Allocate(); GCPtr<B> ptr2 = GC::Allocate(); instead of (what I currently have): GCPtr<A> ptr1 = GC::Allocate<A>(); GCPtr<B> ptr2 = GC::Allocate<B>(); My current Allocate function looks like this: class GC { public: template <typename T> static GCPtr<T> Allocate(); }; Would this be possible to knock off the extra < A and < B? Thanks

  • Best way to map/join two autogenerated enums

    - by tomlip
    What is the best C++ (not C++11) way of joining two enums from autogenerated class similar to one presented below: namespace A { namespace B { ... class CarInfo { enum State { // basically same enums defined in different classes Running, Stopped, Broken } } class BikeInfo { enum State { // basically same enums defined in different classes Running, Stopped, Broken } } } } What is needed is unified enum State for both classes that is seen to outside world alongside with safe type conversion. The best and probably most straightforward way I came up with is to create external enum: enum State { Running, Stopped, Broken } together with conversion functions State stateEnumConv(A::B::CarInfo::State aState); State stateEnumConv(A::B::BikeInfo::State aState); A::B::CarInfo::State stateEnumConv(State aState); A::B::BikeInfo::State stateEnumConv(State aState); Direction into right approach is needed. Gosh coming from C I hate those long namespaces everywhere an I wish it could be only A::B level like in presented example. Four conversion functions seem redundant note that CarInfo::State and BikeInfo::State has same enum "members".

  • C# Bug or Brain Teaser? Cast working only with Coalesce (??) Operator

    - by Alex
    This is very strange, maybe someone can explain what's happening, or this is a bug (though I tend to think that this is probably just something intricate about C#). The following code throws the error "Cannot implicitly convert type 'uint?' to 'uint'.": public void Test(UInt32? p) { UInt32 x = p; } However, this code works without error: public void Test(UInt32? p) { UInt32 x = p ?? 1; } Huh? Why does this work? Why would the coalesce operator cause implicit conversion of UInt32? (nullable) to UInt32 (non-nullable), while the first error message says that there is no implicit conversion between those types?

  • NSFetchedResultsChangeInsert reported when only updates are taking place

    - by niblha
    I have a class that acts as a NSFetchedResultsControllerDelegate which is receiving messages to -(void)controller:didChangeObject:atIndexPath:forChangeType:newIndexPath: with change type NSFetchedResultsChangeInsert, but the actual object which is the subject has with certainty not been newly inserted, only updated. So I would expect to get a change message with type NSFetchedResultsChangeUpdate, should I not? If i check the value of isInserted on the object, it yields false (as expected from the logic in my program). So my question is, why is this reported as an insert when it is only a change/update? They only thing I can think of is that part of the changes that are taking place is that objects of another entity type are inserted with relationships to objects of the entity type that the NSFetchedResultsController is set up to fetch.

  • Custom android preference type loses focus when typing

    - by Brian
    I created a simple preference class that shows an AutoCompleteTextView control and it displays properly but when i focus on the AutoCompleteTextView and start typing it brings up the keyboard but then immediately loses focus on the control. Any idea why this loses focus? Here's what i did to create the view. the inflated layout is just a basic linear layout with a title textview in it. I could change it to a dialog preference instead I guess but it'd be smoother if it could be part of the base view. @Override protected View onCreateView(ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); LinearLayout layout = (LinearLayout) inflater.inflate(R.layout.base_preference, null); if (mHint != null) { TextView hintView = (TextView) layout.findViewById(R.id.PreferenceHintTextView); hintView.setText(mHint); } TextView titleView = (TextView) layout.findViewById(R.id.PreferenceTitleTextView); titleView.setText(getTitle()); AutoCompleteTextView inputView = new AutoCompleteTextView(getContext()); inputView.setGravity(Gravity.FILL_HORIZONTAL); ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(getContext(), R.layout.auto_complete_text_list_item, getEntries()); inputView.setAdapter(adapter); inputView.setThreshold(1); inputView.setOnItemSelectedListener(this); layout.addView(inputView); return layout; }
