  • Empty files generated from running `mysqldump` using PHP

    - by alex
    I keep getting empty files generated from running $command = 'mysqldump --opt -h localhost -u username -p \'password\' dbname > \'backup 2009-04-15 09-57-13.sql\''; command($command); Anyone know what might be causing this? My password has strange characters in it, but works fine with connecting to the db. I've ran exec($command, $return) and outputted the $return array and it is finding the command. I've also ran it with mysqldump > file.sql and the file contains Usage: mysqldump [OPTIONS] database [tables] OR mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...] OR mysqldump [OPTIONS] --all-databases [OPTIONS] For more options, use mysqldump --help So it would seem like the command is working.

  • database search function on an HTML page possible?

    - by synergy989
    Not sure if this is against stackoverflow rules as it's not a specific code question but I really need a little help. I want to know if it is possible to create a search feature (search box) on an HTML webpage that will query a database and return the results? Basically I have a database of products and their related categories. A user would come to the website, enter the category in the search field...somehow query the database and return the results on a new page. Note: the results page doesn't have to be HTML (could be PHP etc). If you could also include a little guidance on how (please nothing detailed, just need a direction). Thank you!

  • 'Random' Orderby in webservice using LINQ To Entities

    - by MrDean
    Morning all Now I know there is a reason to this odering but my tiny little brain can't get my head around it. I am using a webservice to pull through data to a webp[age and have the following that is so far pulling data through from UUF1: public string[] GetBuyer(string Memberkey) { try { WebService.EntitiesConnection buyer = new WebService.EntitiesConnection(); return buyer.tblProducts .Where(p => p.MemberId == Memberkey) .OrderBy(p => p.UnitUserfield1) .Select(p => p.UnitUserfield1) .Distinct() .ToArray(); } catch (Exception) { return null; } } This works fine and pulls the data through but in a strange order. Where I would expect results of A B C D E F, it appears to be returning A C E B D F. Could someone point out the error in my ways please?

  • one-liner if statements...

    - by snickered
    Total noob here so be gentle. I've looked everywhere and can't seem to find the answer to this. How do I condense the following? if (expression) { return true; } else { return false; } I can't get it to work since it's returning something vs. setting something. I've already seen things like this: somevar = (expression) ? value1 : value2; Like I said, please be gentle :)

  • Searching in a TreeMap (Java)

    - by Kronen
    I need to do a search in a map of maps and return the keys this element belong. I think this implementation is very slow, can you help me to optimize it?. I need to use TreeSet and I can't use contains because they use compareTo, and equals/compareTo pair are implemented in an incompatible way and I can't change that. (sorry my bad english) Map m = new TreeSet(); public String getKeys(Element element) { for(Entry e : m.entrySet()) { mapSubKey = e.getValue(); for(Entry e2 : mapSubKey.entrySet()) { setElements = e2.getValue(); for(Element elem : setElements) if(elem.equals(element)) return "Key: " + e.getKey() + " SubKey: " + e2.getKey(); } } }

  • How to get data from dynamically created EditText views and insert it into an array?

    - by Snwspeckle
    So basically what I need my program to do at this point is that when I click the submit button, I need to loop through each dynamic row of the ListView and grab the value in the EditText view and then insert that into an array which I will do further calculations after. Here is my code right now. package com.hello_world; import java.util.ArrayList; import com.hello_world.ByteInputActivity.MyAdapter.ViewHolder; import android.app.Activity; import android.content.Context; import android.os.Bundle; import android.util.Log; import android.view.KeyEvent; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnFocusChangeListener; import android.view.View.OnKeyListener; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.Button; import android.widget.EditText; import android.widget.ListView; import android.widget.TextView; public class ByteInputActivity extends Activity { private ListView myList; private MyAdapter myAdapter; private Integer resQuestions; private Integer indexVal = 0; private View caption; ViewHolder holder; ArrayList<Integer> intArrayList = new ArrayList<Integer>(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fieldlist); //Gets number of questions from MainActivity Bundle extras = getIntent().getExtras(); if(extras !=null) { resQuestions = extras.getInt("index"); } myList = (ListView) findViewById(R.id.FieldList); myList.setItemsCanFocus(true); myAdapter = new MyAdapter(); myList.setAdapter(myAdapter); Button submit = (Button) findViewById(R.id.btn_New); submit.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { for (int i = 0; i < myList.getCount() ; i++) { View vListSortOrder; vListSortOrder = myList.getChildAt(i); String temp = holder.caption.getText().toString(); Log.e("VALUES", "" +temp); } } }); } public class MyAdapter extends BaseAdapter { private LayoutInflater mInflater; public ArrayList myItems = new ArrayList(); public MyAdapter() { mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); for (int i = 0; i < resQuestions; i++) { ListItem listItem = new ListItem(); listItem.caption = "Index " + i; listItem.indexText = "Index " + i; myItems.add(listItem); indexVal += 1; } notifyDataSetChanged(); } public int getCount() { return myItems.size(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { holder = new ViewHolder(); convertView = mInflater.inflate(R.layout.item, null); holder.indexText = (TextView) convertView .findViewById(R.id.textView1); holder.caption = (EditText) convertView .findViewById(R.id.ItemCaption); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } //Fill EditText with the value you have in data source holder.caption.setText(""); holder.caption.setId(position); holder.indexText.setText("Index " + position); holder.indexText.setId(position); //we need to update adapter once we finish with editing holder.caption.setOnFocusChangeListener(new OnFocusChangeListener() { public void onFocusChange(View v, boolean hasFocus) { if (!hasFocus){ final int position = v.getId(); final EditText Caption = (EditText) v; myItems.set(position, Caption.getText().toString()); } } }); return convertView; } class ViewHolder { EditText caption; TextView indexText; } class ListItem { String caption; String indexText; } } }

  • assigning a string to another string

    - by user1509676
    Why this code is not running? Why str1 is not assigned to str2 ?? I know i have an option of using strcpy but i wish to know the reason why this is not working?? #include<stdio.h> int main() { char str1[]="hello"; char str2[10]; str2=str1; printf("%s",str2); return 0; } Whereas if I use pointers than it works like here.. #include<stdio.h> int main() ( char *s="good morning"; char *q; q=s; while(*q!='\0') { printf("%c",*q); q++; } return 0; } This works. Now the string has been copied via pointers so why such difference??

  • singleton pattern in java- lazy Intialization

    - by flash
    public static MySingleton getInstance() { if (_instance==null) { synchronized (MySingleton.class) { _instance = new MySingleton(); } } return _instance; } 1.is there a flaw with the above implementation of the getInstance method? 2.What is the difference between the two implementations.? public static synchronized MySingleton getInstance() { if (_instance==null) { _instance = new MySingleton(); } return _instance; } I have seen a lot of answers on the singleton pattern in stackoverflow but the question I have posted is to know mainly difference of 'synchronize' at method and block level in this particular case.

  • Switching back into the middle of a function in Actionscript

    - by J.Ded.
    I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards. The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?

  • HandsOnTable - using date functions with methods

    - by briansol
    I have a function used on the datepicker to limit dates selected to the first of the month... I invoke it by setting a class and listener, such as: $( ".datepickfom" ).datepicker( { beforeShowDay: fom, showOn: "both", buttonImage: "/images/calendar.png", buttonImageOnly: true, changeMonth: true, changeYear: true, dateFormat: "m/d/yy", yearRange: "-25:+100", constrainInput: true } ); the fom call: function fom(date){ if (date.getDate() != 1) { return [false, "", "Specify 1st of Month"]; } return [true, ""]; } This works great for regular forms. I'm looking to extend this functionality to the HandsOnTable 'date' cell data types. var $container_1 = $("#datatable_1"); var handsontable_1 = $container_1.data('handsontable'); $("#datatable_1").handsontable( { columns: [ {}, {}, { type: 'date', dateFormat: 'm/d/yy' }, {}, { type: 'dropdown', source: ["","Y","N"] }, {}, {} ] }); This also works as it should, but the date lets me pick other dates besides the first. Is there a way to attach the beforeShowDay option to the HOT cell call as well?

  • How do I put these: @{$subset}, [@ext_subset], [$last_item] in PHP?

    - by Alex
    I'm having trouble translating a subroutine from Perl to PHP (I'm new to Perl). The entire subroutine is as follows: sub find_all_subsets { if (1 == scalar (@_)) {return [@_]} else { my @all_subsets = () ; my $last_item = pop (@_) ; my @first_subsets = find_all_subsets (@_) ; foreach my $subset (@first_subsets) { push (@all_subsets, $subset) ; my @ext_subset = @{$subset} ; push (@ext_subset, $last_item) ; push (@all_subsets, [@ext_subset]) ; } push (@all_subsets, [$last_item]) ; return (@all_subsets) ; } } My problem is that I really don't quite understand the Perl syntax, so I'm having trouble writing these @{$subset}, [@ext_subset] and [$last_item] in PHP. Thanks and sorry if the question is stupid.

  • Creating Oracle stored procedure that returns data

    - by user3614327
    In Firebird you can create a stored procedure that returns data an invoke it like a table passing the arguments: create or alter procedure SEL_MAS_IVA ( PCANTIDAD double precision) returns ( CANTIDAD_CONIVA double precision) as begin CANTIDAD_CONIVA = pCANTIDAD*(1.16); suspend; end select * from SEL_MAS_IVA(100) will return a single row single column (named CANTIDAD_CONIVA) relation with the value 116 This is a very simple example. The stored procedure can of course have any number of input and output parameters and do whatever it needs to return data (including multiple rows), which is accomplished by the "suspend" statement (which as it name implies, suspends the SP execution, returns data to the caller, and resumes with the next statement) How can I create such kind of stored procedures in Oracle?

  • How to get a List ordered by the List it's filtered by?

    - by DaveDev
    I have a method as follows. It returns a list of MyTypes which appear to be ordered by myType.Id ascending by default. public List<MyType> GetMyTypes(List<int> ids) { return (from myType in db.MyTypes where ids.Contains(myType.Id) select new MyType { MyValue = myType.MyValue }).ToList(); } So if ids contains 302 300 301 the List returned contains items in ascending order. What do I need to do to return List<MyType> in the order of ids? Thanks edit: I've tried orderby ids.IndexOf(myType.Id) but it throws the exception Method 'Int32 IndexOf(Int32)' has no supported translation to SQL.

  • javascript timer fires up on the first key press

    - by pedrag
    I have a html page with a timer in it. I'm starting the timer with the keypress event, but i want it to execute only for the first key. I'm using a variable to catch the total keys in an other function which there were pressed and i have something like that: if(totaAttempts==1) start the timer, but with this solution the timer starts correctly, but is stomps when a key is pressed again. Any better ideas? Thanks in advance function setTime() { if (totalAttempts == 1) { ++totalSeconds; secondsLabel.innerHTML = pad(totalSeconds % 60); minutesLabel.innerHTML = pad(parseInt(totalSeconds / 60)); } } function pad(val) { var valString = val + ""; if (valString.length < 2) { return "0" + valString; } else { return valString; } }

  • C++ OOP: Which functions to put into the class?

    - by oh boy
    Assume I have a class a: class a { public: void load_data( ); private: void check_data( ); void work_data( ); void analyze_data( ); } Those functions all do something with the class or one of its members. However this function: bool validate_something( myType myData ) { if ( myData.blah > 0 && myData.blah < 100 ) { return true; } return false; } Is related to the class and will only be called by it, so it won't be needed anywhere else Doesn't do anything with the class or its members - just a small "utility" function Where to put validate_something? Inside or outside the class?

  • NSString inheritance

    - by Stef

  • javascript call url from different domain

    - by user246114
    Hi, I want to post some data via javascript to another domain. Something like: http://www.othersite.com/submitfunnyname?name=blah The other site (othersite.com) has a REST interface that you can call (well actually this is a get example) to submit a funny name to them. Can I do this already with javascript? I'm a little confused on this - I know if that service wants to return some data, I'd need to use something like JSON-P - even though here I'm submitting some data, I guess the service will return some message structure letting me know the result, so it would have to be JSON-P, right? Thanks

    Is it possible for multiple wcf services to implement the same service contract interface? What I want to do is allow for a test service to be interchangeable for the real service, and to specify which service to be used in the configuration file. For example: [ServiceContract] public interface IUselessService { [OperationContract] string GetData(int value); } Test implementation public class TestService : IUselessService { public string GetData(int value) { return "This is a test"; } } Real class public class RealService : IUselessService { public string GetData(int value) { return string.Format("You entered: {0}", value); } }

  • extracting string occurrence in c

    I have a string from a text file that look something like this: long_str = "returns between paragraphs 20102/34.23" - 9203 1232 "test" "basic HTML" Note: Quotes are part of the string. int match(char *long_str){ char * str; if ((str = strchr(long_str, '"')) != NULL) str++; // last " ? else return 1; return 0; } Using strstr I'm trying to get the whole substring between the last two quotes: "basic HTML". I'm just not quite sure what would be a good and efficient way of getting that match. I'm open to any other ideas on how to approach this. Thanks
