  • Connecting form to database errors

    - by Russell Ehrnsberger
    Hello I am trying to connect a page to a MySQL database for newsletter signup. I have the database with 3 fields, id, name, email. The database is named newsletter and the table is named newsletter. Everything seems to be fine but I am getting this error Notice: Undefined index: Name in C:\wamp\www\insert.php on line 12 Notice: Undefined index: Name in C:\wamp\www\insert.php on line 13 Here is my form code. <form action="insert.php" method="post"> <input type="text" value="Name" name="Name" id="Name" class="txtfield" onblur="javascript:if(this.value==''){this.value=this.defaultValue;}" onfocus="javascript:if(this.value==this.defaultValue){this.value='';}" /> <input type="text" value="Enter Email Address" name="Email" id="Email" class="txtfield" onblur="javascript:if(this.value==''){this.value=this.defaultValue;}" onfocus="javascript:if(this.value==this.defaultValue){this.value='';}" /> <input type="submit" value="" class="button" /> </form> Here is my insert.php file. <?php $host="localhost"; // Host name $username="root"; // Mysql username $password=""; // Mysql password $db_name="newsletter"; // Database name $tbl_name="newsletter"; // Table name // Connect to server and select database. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // Get values from form $name=$_POST['Name']; $email=$_POST['Email']; // Insert data into mysql $sql="INSERT INTO $tbl_name(name, email)VALUES('$name', '$email')"; $result=mysql_query($sql); // if successfully insert data into database, displays message "Successful". if($result){ echo "Successful"; echo "<BR>"; echo "<a href='index.html'>Back to main page</a>"; } else { echo "ERROR"; } ?> <?php // close connection mysql_close(); ?>

  • reduce bandwidth streaming mp3s php...

    - by Scarface
    Hey guys, quick question for any experts out there. I am allowing users to upload and post mp3s so other users can listen to/stream. I was wondering if anyone had any tips for reducing bandwidth, or any tips or methods for streaming mp3s. I currently just reference the location of the file with my flash mp3 player after the file has been uploaded. I would ask about images as well, but I am pretty sure they can be compressed using gzip or mod_deflate

  • g++ linker error--typeinfo, but not vtable

    - by James
    I know the standard answer for a linker error about missing typeinfo usually also involves vtable and some virtual function that I forgot to actually define. I'm fairly certain that's not the situation this time. Here's the error: UI.o: In function boost::shared_ptr<Graphics::Widgets::WidgetSet>::shared_ptr<Graphics::Resource::GroupByState>(boost::shared_ptr<Graphics::Resource::GroupByState> const&, boost::detail::dynamic_cast_tag)': UI.cpp:(.text._ZN5boost10shared_ptrIN8Graphics7Widgets9WidgetSetEEC1INS1_8Resource12GroupByStateEEERKNS0_IT_EENS_6detail16dynamic_cast_tagE[boost::shared_ptr<Graphics::Widgets::WidgetSet>::shared_ptr<Graphics::Resource::GroupByState>(boost::shared_ptr<Graphics::Resource::GroupByState> const&, boost::detail::dynamic_cast_tag)]+0x30): undefined reference totypeinfo for Graphics::Widgets::WidgetSet' Running c++filt on the obnoxious mangled name shows that it actually is looking at .boost::shared_ptr::shared_ptr(boost::shared_ptr const&, boost::detail::dynamic_cast_tag) The inheritance hierarchy looks something like class AbstractGroup { typedef boost::shared_ptr<AbstractGroup> Ptr; ... }; class WidgetSet : public AbstractGroup { typedef boost::shared_ptr<WidgetSet> Ptr; ... }; class GroupByState : public AbstractGroup { ... }; Then there's this: class UI : public GroupByState { ... void LoadWidgets( GroupByState::Ptr resource ); }; Then the original implementation: void UI::LoadWidgets( GroupByState::Ptr resource ) { WidgetSet::Ptr tmp( boost::dynamic_pointer_cast< WidgetSet >(resource) ); if( tmp ) { ... } } Stupid error on my part (trying to cast to a sibling class with a shared parent), even if the error is kind of cryptic. Changing to this: void UI::LoadWidgets( AbstractGroup::Ptr resource ) { WidgetSet::Ptr tmp( boost::dynamic_pointer_cast< WidgetSet >(resource) ); if( tmp ) { ... } } (which I'm fairly sure is what I actually meant to be doing) left me with a very similar error: UI.o: In function boost::shared_ptr<Graphics::Widgets::WidgetSet>::shared_ptr<Graphics::_Drawer::Group>(boost::shared_ptr<Graphics::_Drawer::Group> const&, boost::detail::dynamic_cast_tag)': UI.cpp:(.text._ZN5boost10shared_ptrIN8Graphics7Widgets9WidgetSetEEC1INS1_7_Drawer5GroupEEERKNS0_IT_EENS_6detail16dynamic_cast_tagE[boost::shared_ptr<Graphics::Widgets::WidgetSet>::shared_ptr<Graphics::_Drawer::Group>(boost::shared_ptr<Graphics::_Drawer::Group> const&, boost::detail::dynamic_cast_tag)]+0x30): undefined reference totypeinfo for Graphics::Widgets::WidgetSet' collect2: ld returned 1 exit status dynamic_cast_tag is just an empty struct in boost/shared_ptr.hpp. It's just a guess that boost might have anything at all to do with the error. Passing in a WidgetSet::Ptr totally eliminates the need for a cast, and it builds fine (which is why I think there's more going on than the standard answer for this question). Obviously, I'm trimming away a lot of details that might be important. My next step is to cut it down to the smallest example that fails to build, but I figured I'd try the lazy way out and take a stab on here first. TIA!

  • Start with Java (JVM) ecosystem

    - by Kaveh Shahbazian
    I have came from another question to this one: How can one start with Java (JVM) ecosystem? What are beginner, intermediate and advanced knowledge-bases (bags!)? To be honest Java ecosystem was always a bit confusing to me, so it would be very helpful to provide some "reference references" and "defacto tutorials" for learning (curve!) JVM. I am a C# developer (WPF, Windows Forms, ASP.NET, Web Services, ... like that).

  • How to receive the text which was sent by SendText

    - by thillai-selvan
    In asterisk I have sent a text message using SendText as follows I have two registered users in sip.conf file. sip.conf details [thillai] username=thillai secret=thillai host=dynamic type=friend allow=all context=test [selvan] username=selvan secret=selvan allow=all host=dynamic type=friend context=test Then I have created the necessary extensions like this extensions.conf file: [test] exten = 677,1,BackGround(thankyou) exten = 677,n,Dial(SIP/thillai) exten = 677,n,SendText('this is for testing') So when a caller is trying to call to extension 677 this text information will be sent. My question is how can I receive this text in the caller side? Any help will be much appreciated.

  • C# dependency injection - how to you inject a dependency without source?

    - by Phil Harris
    Hi, I am trying to get started with some simple dependency injection using C# and i've run up against an issue that I can't seem to come up with an answer for. I have a class that was written by another department for which I don't have the source in my project. I wanted to inject an object of this type though a constructor using an interface, but of course, i can't change the injected objects implementation to implement the interface to achieve polymorphism when casting the object to the interface type. Every academic example I have ever seen of this technique has the classes uses classes which are declared in the project itself. How would I go about injecting my dependency without the source being available in the project? I hope that makes sense, thanks.

  • Inheritance in tables - structure problem

    - by Naor
    I have 3 types of users in my system. each type has different information I created the following tables: BaseUser(base_user_id, username, password, additional common data) base_user_id is PK and Identity UserType1(user_id, data related to type1 only) user_id is PK and FK to base_user_id UserType2(user_id, data related to type2 only) user_id is PK and FK to base_user_id UserType3(user_id, data related to type3 only) user_id is PK and FK to base_user_id Now I have relation from each type of user to warehouses table. Users from type1 and type2 should have only warehouse_id and users from type3 should have warehouse_id and customer_id. I thought about this structure: WarehouseOfUser(base_user_id,warehouse_id) base_user_id is FK to base_user_id in BaseUser WarehouseOfTyp3User(base_user_id,warehouse_id, customer_id) base_user_id is FK to base_user_id in BaseUser The problem is that such structure allows 2 things I want to prevent: 1. add to WarehouseOfTyp3User data of user from type2 or type1. 2. add to WarehouseOfUser data of user from type3. what is the best structure for such case?

  • Is there a way to determine the Variance of an Interface / Delegate in C# 4.0?

    - by BFree
    So now that we have generic Covariance and Contravariance on interfaces and delegates in C#, I was just curious if given a Type, you can figure out the covariance/contravariance of its generic arguments. I started trying to write my own implementation, which would look through all of the methods on a given type and see if the return types and or arguments match the types in the generic arguments. The problem is that even if I have this: public interface IFoo<T> { void DoSomething(T item); } using my logic, it LOOKS like it should be contravariant, but since we didn't actually specify: public interface IFoo<in T> { void DoSomething(T item); } (the in parameter) it isn't actually contravariant. Which leads to my question: Is there a way to determine the variance of generic parameters?

Is there any way i can optimize so it uses less rows to scan and get the data. Also, id is the primary key column.

  • Dynamic Dispatch without Virtual Functions

    - by Kristopher Johnson
    I've got some legacy code that, instead of virtual functions, uses a kind field to do dynamic dispatch. It looks something like this: // Base struct shared by all subtypes // Plain-old data; can't use virtual functions struct POD { int kind; int GetFoo(); int GetBar(); int GetBaz(); int GetXyzzy(); }; enum Kind { Kind_Derived1, Kind_Derived2, Kind_Derived3 }; struct Derived1: POD { Derived1(): kind(Kind_Derived1) {} int GetFoo(); int GetBar(); int GetBaz(); int GetXyzzy(); // plus other type-specific data and function members }; struct Derived2: POD { Derived2(): kind(Kind_Derived2) {} int GetFoo(); int GetBar(); int GetBaz(); int GetXyzzy(); // plus other type-specific data and function members }; struct Derived3: POD { Derived3(): kind(Kind_Derived3) {} int GetFoo(); int GetBar(); int GetBaz(); int GetXyzzy(); // plus other type-specific data and function members }; and then the POD class's function members are implemented like this: int POD::GetFoo() { // Call kind-specific function switch (kind) { case Kind_Derived1: { Derived1 *pDerived1 = static_cast<Derived1*>(this); return pDerived1->GetFoo(); } case Kind_Derived2: { Derived2 *pDerived2 = static_cast<Derived2*>(this); return pDerived2->GetFoo(); } case Kind_Derived3: { Derived3 *pDerived3 = static_cast<Derived3*>(this); return pDerived3->GetFoo(); } default: throw UnknownKindException(kind, "GetFoo"); } } POD::GetBar(), POD::GetBaz(), POD::GetXyzzy(), and other members are implemented similarly. This example is simplified. The actual code has about a dozen different subtypes of POD, and a couple dozen methods. New subtypes of POD and new methods are added pretty frequently, and so every time we do that, we have to update all these switch statements. The typical way to handle this would be to declare the function members virtual in the POD class, but we can't do that because the objects reside in shared memory. There is a lot of code that depends on these structs being plain-old-data, so even if I could figure out some way to have virtual functions in shared-memory objects, I wouldn't want to do that. So, I'm looking for suggestions as to the best way to clean this up so that all the knowledge of how to call the subtype methods is centralized in one place, rather than scattered among a couple dozen switch statements in a couple dozen functions. What occurs to me is that I can create some sort of adapter class that wraps a POD and uses templates to minimize the redundancy. But before I start down that path, I'd like to know how others have dealt with this.

  • Log4net appender filename issue

    - by JL
    I have an appender setup like this <appender name="Scheduler_Appender" type="log4net.Appender.RollingFileAppender"> <file value="c:\temp\ApplicationLog.txt"/> <rollingStyle value="Date"/> <datePattern value="yyyyMMdd"/> <appendToFile value="true"/> <staticLogFileName value="true"/> <layout type="MinLayout"> <locationInfo value="true"/> </layout> </appender> When the log file first gets created the file name is simply ApplicationLog.txt this is correct. However when the logging rolls - the filename that gets generated is ApplicationLog.txt20100323 (for example), and not ApplicationLog20100323.txt How can I change the configuration so files are rolled to [FileName][Date].[ext] rather than [FileName].[ext][Date] Thanks

  • XSD.exe question about include files and code generation

    - by Roger Willcocks
    If you have an XSD with an includes reference. Is it possible to generate 2 separate class files. 1 for the XSD, and 1 for the included XSD? My Scenario 4 XSDs, each of which share 15-20 element definitions in common. Rather than maintaining, I'd like to end up with the 4 XSDs all referencing a fifth file with the common definitions, and code generating 5 .cs files to use.

  • How might one implement FileTimeToSystemTime?

    - by Billy ONeal
    Hello :) I'm writing a simple wrapper around the Win32 FILETIME structure. boost::datetime has most of what I want, except I need whatever date type I end up using to interpolate with Windows APIs without issues. To that end, I've decided to write my own things for doing this -- most of the operations aren't all that complicated. I'm implementing the TimeSpan - like type at this point, but I'm unsure how I'd implement FileTimeToSystemTime. I could just use the system's built-in FileTimeToSystemTime function, except FileTimeToSystemTime cannot handle negative dates -- I need to be able to represent something like "-12 seconds". How should something like this be implemented? Billy3

  • Is there a way to query if array field contains a certain value in Doctrine2?

    - by dpimka
    Starting out with Symfony2 + Doctrine. I have a table with User objects (fos_user), for which my schema contains a roles column of an 'array' type. Doctrine saves fields of this type by serializing them from php 'array' to 'longtext' (in mysql's case). So let's say I have the following users saved into DB: **User1**: array(ROLE_ADMIN, ROLE_CUSTOM1) **User2**: array(ROLE_ADMIN, ROLE_CUSTOM2) **User3**: array(ROLE_CUSTOM2) Now in my controller I want to select all users with ROLE_ADMIN set. Is there a way to write a DQL query which would directly return me User1 and User2? Or do I need to fetch all users to have Doctrine to unserialize roles column and then for each of them do in_array('ROLE_ADMIN', $user-getRoles())? I have searched the DQL part of the manual, but so far did not find anything similar to my needs...

  • Openlayers and Bing Maps (POLYGONS)

    - by Jordan
    When trying to draw polygons onto a bing map, the initial marker is set differently on the map. How can I fix this? OpenLayers Bing Example <script src="OpenLayers.js"></script> <script> var map; function init(){ map = new OpenLayers.Map("map"); map.addControl(new OpenLayers.Control.LayerSwitcher()); var shaded = new OpenLayers.Layer.VirtualEarth("Shaded", { type: VEMapStyle.Shaded }); var hybrid = new OpenLayers.Layer.VirtualEarth("Hybrid", { type: VEMapStyle.Hybrid }); var aerial = new OpenLayers.Layer.VirtualEarth("Aerial", { type: VEMapStyle.Aerial }); var POLY_LAYER = new OpenLayers.Layer.Vector(); map.addLayers([shaded, hybrid, aerial, POLY_LAYER]); map.setCenter(new OpenLayers.LonLat(-110, 45), 3); var polygon = new OpenLayers.Control.DrawFeature(POLY_LAYER, OpenLayers.Handler.Polygon); map.addControl(polygon); polygon.activate(); } </script> Bing Example <div id="tags"> Bing, Microsoft, Virtual Earth </div> <p id="shortdesc"> Demonstrates the use of Bing layers. </p> <div id="map" class="smallmap"></div> <div id="docs">This example demonstrates the ability to create layers using tiles from Bing maps.</div> Of course the above is being initialized and page works. You can draw the polygon shapes. Notice if you zoom in or out one time, the markers are set at the correct coordinates. My app I was testing this on is really using the bing maps API keys and not VirtualEarth. But it's doing a similar thing. Is this an Openlayers bug? The below source came directly from the open layers example site, I just added and activated polygons to the map. Please let me know how I can fix this for using the Bing Map API.. I've been stuck on this for HOURS! :(
