  • Smart way to execute function in flash from an imported html (or XML) plain text

    - by DomingoSL
    Ok, here is the think. I have a very simple flash program code in AS3, inside this program there is a dynamic textfield html capable. Also i have a database were i will put some information. Each element in the database can be linked to other. For example, this database will contain tourist spots, and they can be related with others in the same database. Ramdom place 1 This interesting spot is near <link to="ramdo2">ramdom place2</link>. And so, so so... The information in the database is retrived by the flash application and it shows the text on the dynamic textfield. I need somehow to tell my flash application that have to be a link to other part of the database, so when the user click the link a function in flash call this new data. The database is a simple Mysql server, and the data is not yet in there, waiting for your suggestions of how to format it and develop the solution. Im a php developer too, so i can make a gateway in PHP to read the MySQL and then retrive some format to flash, an XML for example.

  • Memory optimization while downloading

    - by lboregard
    hello all i have the following piece of code, that im looking forward to optimize, since i'm consuming gobs of memory this routine is heavily used first optimization would be to move the stringbuilder construction out of the download routine and make it a field of the class, then i would clear it inside the routine can you please suggest any other optimization or point me in the direction of some resources that could help me with this (web articles, books, etc). i'm thinking about replacing the stringbuilder by a fixed (much larger) size buffer ... or perhaps create a larger sized stringbuilder thanks in advance. StreamWriter _writer; StreamReader _reader; public string Download(string msgId) { _writer.WriteLine("BODY <" + msgId + ">"); string response = _reader.ReadLine(); if (!response.StartsWith("222")) return null; bool done = false; StringBuilder body = new StringBuilder(256* 1024); do { response = _reader.ReadLine(); if (OnProgress != null) OnProgress(response.Length); if (response == ".") { done = true; } else { if (response.StartsWith("..")) response = response.Remove(0, 1); body.Append(response); body.Append("\r\n"); } } while (!done); return body.ToString(); }

  • Access Question

    - by kralco626
    I have a record set for inspections of many peices of equipment. The four cols of interest are equip_id,month,year,myData. My requirment is to have EXACTLY ONE Record per month for each peice of equipment. I have a quiery that makes the data unique over equip_id,month,year. So there is no more than one record for each month/year for a peice of equipment. But now I need to simulate data for the missing month. I want to simply go back in time to get the last peice of my data. So that may seem confusing, so i'll show by example. Given this: equip_id month year myData 1 1 2010 500 1 2 2010 600 1 5 2010 800 2 2 2010 300 2 4 2010 400 2 6 2010 500 I want this: equip_id month year myData 1 1 2010 500 1 2 2010 600 1 3 2010 600 1 4 2010 600 1 5 2010 800 2 2 2010 300 2 3 2010 300 2 4 2010 400 2 5 2010 400 2 6 2010 500 Notice that im filling in missing data with the data from the month ( or two months etc.) before. Also note that if the first record for equip 2 is in 2/2010 than I don't need a record for 1/2010 even though I have one for equip 1. I just need exactly one record for each month/year for each peice of equipment. So if the record does not exsist I just want to go back in time and grab the data for that record. Thanks!!!

  • jquery suspected naving convention problem

    - by donfigga
    Hi all im having provlem with this jquery function, the protion of the function that renames the id, class and name of the dropdown only works for the first dropdown, susequest ones do not work , any ideas, i suspect it may have something to do with naming convention as in cat.parent_id but it is required for asp.net mvc model binding. $(document).ready(function () { $("table select").live("change", function () { var id = $(this).attr('id'); if ($(this).attr('classname') != "selected") { var rowIndex = $(this).closest('tr').prevAll().length; $.getJSON("/Category/GetSubCategories/" + $(this).val(), function (data) { if (data.length > 0) { //problematic portion $("#" + id).attr('classname', 'selected'); $("#" + id).attr('name', 'sel' + rowIndex); $("#" + id).attr('id', 'sel' + rowIndex); var position = ($('table').get(0)); var tr = position.insertRow(rowIndex + 1); var td1 = tr.insertCell(-1); var td2 = tr.insertCell(-1); td1.appendChild(document.createTextNode('SubCategory')); var sel = document.createElement("select"); sel.name = 'parent_id'; sel.id = 'parent_id'; sel.setAttribute('class', 'unselected'); td2.appendChild(sel); $('#parent_id').append($("<option></option>").attr("value", "-1").text("-please select item-")); $.each(data, function (GetSubCatergories, Category) { $('#parent_id').append($("<option></option>"). attr("value", Category.category_id). text(Category.name)); }); sel.name = 'cat.parent_id'; sel.id = 'cat.parent_id'; } }); } }); });

  • How to do this in a smart way

    - by Azzyh
    Hello SO. My websystem im coding with now is integrated from the originally phpBB system. With this i mean when you log on my websystem, you have actually logged into the forum from the login page. Now i came to the "log out" part, and i want to make it smart. Right now its a simply link with logout: <a href="<?php echo BASEDIR; ?>../../ucp.php?mode=logout&sid=<? echo $user->data['session_id']; ?>" style="margin-left: 14px; font-size: 10px;">- Log Out</a> As you see in the link it refers to the forum´s ucp.php?mode=logout, and you need to have the SID variable in it in order to log out right.. anyway.. I want to do this log out part in a smart way, i mean, not so you land on the forum´s "you have now been logged out", i want something maybe like run this page in background when you click, and then it refreshes the current page your on. Or should it be smarter just try to modify the phpbb file ucp.php? I think its hard coded, and not the way I am coding, so thats why i find it abit tricky. Thank you for your answers and examples on how this could be done, in a smart way..

  • C++ design question, container of instances and pointers

    - by Tom
    Hi all, Im wondering something. I have class Polygon, which composes a vector of Line (another class here) class Polygon { std::vector<Line> lines; public: const_iterator begin() const; const_iterator end() const; } On the other hand, I have a function, that calculates a vector of pointers to lines, and based on those lines, should return a pointer to a Polygon. Polygon* foo(Polygon& p){ std::vector<Line> lines = bar (p.begin(),p.end()); return new Polygon(lines); } Here's the question: I can always add a Polygon (vector Is there a better way that dereferencing each element of the vector and assigning it to the existing vector container? //for line in vector<Line*> v //vcopy is an instance of vector<Line> vcopy.push_back(*(v.at(i)) I think not, but I dont really like that approach. Hopefully, I will be able to convince the author of the class to change it, but I cant base my coding right now to that fact (and i'm scared of a performance hit). Thanks in advance.

  • Gearman client doBackground always returns GEARMAN_TIMEOUT

    - by Ascherer
    So, ive got a simple gearman system running right now, with a worker running. The worker basically just takes the payload (a random number in this case, and is supposed to echo it back to the screen. Literally an echo, not returning to the client. The client sends the random number. Im trying to do a $client->doBackground( 'post', 65482, md5(uniqid())); but its coming back with a 47 error (GEARMAN_TIMEOUT) every time. getErrNo() returns 0, error() returns something about GEARMAN_TIMEOUT However, when i change it to just $client->do(blah, blah, blah), it works just fine. I've even occasionally seen it where the worker still echo's the number, even after getting the timeout error... public function execute() { $method = 'do'; if( !$this->getBlock() ) { $method .= ( $this->getPriority() == 'Normal' ? '' : $this->getPriority() ) . 'Background'; } else { $method .= $this->getPriority(); } echo "Method: $method \t Worker: {$this->getName()} \t Payload: {$this->getPayload()} \t Hash: {$this->getHash()}\n"; $this->setResult( $this->getClient() ->$method( $this->getName(), $this->getPayload(), $this->getHash() ) ); if( $this->getClient()->returnCode() != GEARMAN_SUCCESS ) { echo "Code: " . $this->getClient()->returnCode() . "\t" . GEARMAN_TIMEOUT . "\n"; } }

  • Advice on Minimizing Stored Procedure Parameters

    - by RPM1984
    Hi Guys, I have an ASP.NET MVC Web Application that interacts with a SQL Server 2008 database via Entity Framework 4.0. On a particular page, i call a stored procedure in order to pull back some results based on selections on the UI. Now, the UI has around 20 different input selections, ranging from a textbox, dropdown list, checkboxes, etc. Each of those inputs are "grouped" into logical sections. Example: Search box : "Foo" Checkbox A1: ticked, Checkbox A2: unticked Dropdown A: option 3 selected Checkbox B1: ticked, Checkbox B2: ticked, Checkbox B3: unticked So i need to call the SPROC like this: exec SearchPage_FindResults @SearchQuery = 'Foo', @IncludeA1 = 1, @IncludeA2 = 0, @DropDownSelection = 3, @IncludeB1 = 1, @IncludeB2 = 1, @IncludeB3 = 0 The UI is not too important to this question - just wanted to give some perspective. Essentially, i'm pulling back results for a search query, filtering these results based on a bunch of (optional) selections a user can filter on. Now, My questions/queries: What's the best way to pass these parameters to the stored procedure? Are there any tricks/new ways (e.g SQL Server 2008) to do this? Special "table" parameters/arrays - can we pass through User-Defined-Types? Keep in mind im using Entity Framework 4.0 - but could always use classic ADO.NET for this if required. What about XML? What are the serialization/de-serialization costs here? Is it worth it? How about a parameter for each logical section? Comma-seperated perhaps? Just thinking out loud. This page is particulary important from a user point of view, and needs to perform really well. The stored procedure is already heavy in logic, so i want to minimize the performance implications - so keep that in mind. With that said - what is the best approach here?

  • Simple HTML interface to XSD?

    - by Visage
    I'm writing an app that, at its heart, uses a hierarchical tree of nodes in XML, it looks like this: <node> <name>Node1</name> <Attribute1>Something</Attribute1> <Attribute2>SomethingElse</Attribute2> <child>Node2</child> <child>Node4</child> <child>Node7</child> </node> And so on (all child elements must refer to an existing node, though the node inquestion doesnt have to precede the first reference to it) For a simple structure like this is there a simple tool to generate a html page that will allow a user to enter Nodes and dynamically update a server-side xml file? Im basically writing a tool that will use such a file, but the people who's job it is to create the file arent especially techno-literate, so creating the XML by hand is a no-no. I could hand-crank one fairly quickly, but if I can get a tool to do it, even better (especially as the format may change in future)....

  • How can I run an appear effect and a fade effect in scriptaculous? I need them to run in tandam so t

    - by LeeRM
    Hi, Ive been fiddling with this for hours and hours and just cant get it right. First off my sites are already using Prototytpe and Scriptaculous, and to change would take a long time. Basically I am after achieving a slideshow effect similar to jQuery Cycle plugin. I have written most of it but cant get over this hurdle: I need the user to be able to press a control button which will skip the slide to which ever one they have picked. My problem is that if a fade / appear effect is running, then it causes an overlap. I am using queues and they are in their own scope. The problem as I see it is that the fade effect on one slide and the appear effect on the next slide are separate functions. Which means that if the user clicks the control button to move to another slide whilst the animation is inbetween fade & appear, then the next cycle will slot itself in the queue between those 2 effects. The default is to append to the end of the existing queue, which should be fine. But if the appear hasnt been added when a new fade is instantiated, then the queue messes up. I can make it so nothing happens if animation is in effect but thats not the effect I am after. I want to be able to click a slide and whatever is happening to effectively stop and the next slide appear. This is an example of what I am after: http://www.zendesk.com/ Im sorry if that doesnt make sense. Its a tough one to explain. Thanks Lee

  • How would I associate a "Note" class to 4+ classes without creating lookup table for each associatio

    - by Gthompson83
    Im creating a project tasklist application. I have project, section, task, issue classes, and would like to use one class to be able to add simple notes to any object instance of those classes. The task, issue tables both use a standard identity field as a primary key. The section table has a two field primary key. The project table has a single int primary key defined by the user. Is there a way to associate the note class with each of these without using a seperate lookup table for each class? I'm not so sure my original idea is a decent way to implement this. I considered the following (each variable mapping to a field n the notes table. Private _NoteId As Integer Private _ProjectId As Integer Private _SectionId As Integer Private _SectionId2 As Integer Private _TaskId As Integer Private _IssueId As Integer Private _Note As String Private _UserId As Guid Then I would be able to write seperate methods (getProjectNotes, getTaskNotes) to get notes attached to each class. I started writing this a few weeks ago but got pulled away before i could finish. When revisiting this code today my first thought "this is retarded". Thoughts on drawbacks to this design?

  • Assigning Object to View, big MySQL resultset.

    - by A Finn
    Hello (Sorry for my bad English) Is it bad practice to assign object to view and call its methods in there? I use smarty as my template engine. In my controller I could do like this 1# $this->view->assign("name", $this->model->getName); and in my view <p>{$name}</p> OR 2# $this->view->assign("Object", $this->model); and in my view <p>{$Report->getName()}</p> Well my biggest problem is that I have to handle a big amount of data coming out from the MySQL and I thought that if I would made a method that would print out the data while looping mysql_fetch_row. Well at least I know that using html-tags in the model is a bad thing to do. So I would assign the object to the view to get the result to the right position on the page.. Reading a mysql-result to an array first may cause memory problems am I right? So what is the solution doing things MVC style.. And yes Im using a framework of my own.

  • Generic applet style system for publishing mathematics demonstrations?

    - by Alex
    Anyone who's tried to study mathematics using online resources will have come across these Java applets that demonstrate a particular mathematical idea. Examples: http://www.math.ucla.edu/~tao/java/Mobius.html http://www.mathcs.org/java/programs/FFT/index.html I love the idea of this interactive approach because I believe it is very helpful in conveying mathematical principles. I'd like to create a system for visually designing and publishing these 'mathlets' such that they can be created by teachers with little programming experience. So in order to create this app, i'll need a GUI and a 'math engine'. I'll probably be working with .NET because thats what I know best and i'd like to start experimenting with F#. Silverlight appeals to me as a presentation framework for this project (im not worried about interoperability right now). So my questions are: does anything like this exist already in full form? are there any GUI frameworks for displaying mathematical objects such as graphs & equations? are there decent open source libraries that exposes a mathematical framework (Math.NET looks good, just wondering if there is anything else out there) is there any existing work on taking mathematical models/demos built with maple/matlab/octave/mathematica etc and publishing them to the web?

  • basic file input using C

    - by user1781966
    So im working on learning how to do file I/O, but the book I'm using is terrible at teaching how to receive input from a file. Below is is their example of how to receive input from a file, but it doesn't work. I have copied it word for word, and it should loop through a list of names until it reaches the end of the file( or so they say in the book), but it doesn't. In fact if I leave the while loop in there, it doesn't print anything. #include <stdio.h> #include <conio.h> int main() { char name[10]; FILE*pRead; pRead=fopen("test.txt", "r"); if (pRead==NULL) { printf("file cannot be opened"); }else printf("contents of test.txt"); fscanf(pRead,"%s",name); while(!feof(pRead)) { printf("%s\n",name); fscanf(pRead, "%s", name); } getch(); } Even online, every beginners tutorial I see does some variation of this, but I can't seem to get it to work even a little bit.

  • I cant put a string in a switch nor an array in a class

    - by TimothyTech
    Okay, im making a pretty big file in my opinion, so i wanted to separate it into several files for cleaner code. so i have my main .cpp file and two header files holding my classes. well the header files dont hold strings, it aboslutely wont budge. i call the library in both my .cpp file and even tried it in my header file. another issue i ran into is using strings to make switches function, reason being if i use integers in a switch if the user inputs a alphabetical character the program goes into an endless loop. string choice; switch (choice) { case "1" : //... break; case "2" : //... break; } and my last issue is when i create an object in a case it gives an error. says cross initialization of object. string choice; switch (choice) { case "1" : Class object; break; case "2" : //... break; }

  • c# creating a database query METHOD

    - by Sinaesthetic
    I'm not sure if im delluded but what I would like to do is create a method that will return the results of a query, so that i can reuse the connection code. As i understand it, a query returns an object but how do i pass that object back? I want to send the query into the method as a string argument, and have it return the results so that I can use them. Here's what i have which was a stab in the dark, it obviously doesn't work. This example is me trying to populate a listbox with the results of a query; the sheet name is Employees and the field/column is name. The error i get is "Complex DataBinding accepts as a data source either an IList or an IListSource.". any ideas? public Form1() { InitializeComponent(); openFileDialog1.ShowDialog(); openedFile = openFileDialog1.FileName; lbxEmployeeNames.DataSource = Query("Select [name] FROM [Employees$]"); } public object Query(string sql) { System.Data.OleDb.OleDbConnection MyConnection; System.Data.OleDb.OleDbCommand myCommand = new System.Data.OleDb.OleDbCommand(); string connectionPath; //build connection string connectionPath = "provider=Microsoft.Jet.OLEDB.4.0;Data Source='" + openedFile + "';Extended Properties=Excel 8.0;"; MyConnection = new System.Data.OleDb.OleDbConnection(connectionPath); MyConnection.Open(); myCommand.Connection = MyConnection; myCommand.CommandText = sql; return myCommand.ExecuteNonQuery(); }
