• AngularJS Bind Attribute Presence

  - by Chuck

  I want to bind the presence of an attribute to a variable in AngularJS. Specifically, sandbox for an iframe. Say I have $myCtrl.allowJavascript as a variable, I want to do: <iframe src="..." sandbox /> Where the sandbox attribute is present when allowJavascript == false, and I want the sandbox attribute to disappear when allowJavascript == true. Does AngularJS have a mechanism for this? The closest thing I could find was here, which basically says "it will just work for certain attributes"--but not for sandbox.

• is it possible to write data to a collection in wpf?

  - by randyc

  Hello. In looking through samples I have seen a number of examples where it is possible to present data within a wpf applicaiton by binding to collections. However I was wondering is it possible to write to a collection from an applicaiton. Say for example i have 2 or more fields such as names and I wanted to have hte ability to add up to three names in my application ( all stored in memory). Will collections serve this purpose. In the past with asp.net I have done this by creating data tables and storing values on the fly or during the session. I am trying to learn WPF and I was wondering if collections work in the same fashion? If so could you please post an example or point me to references that show examples of this? Thank you in advance.

• Is my Perl script grabbing environment variabless from "someplace else"?

  - by Michael Wilson

  On a Solaris box in a "mysterious production system" I'm running a Perl script that references an environment variable. No big deal. The contents of that variable from the shell both pre- and post-execution are what I expect. However, when reported by the script, it appears as though it's running in some other sub-shell which is clobbering my vars with different values for the duration of the script. Unfortunately I really can't paste the code. I'm trying to get an atomic case, but I'm at my wit's end here.

• Hiding result sets from multiple selects in a stored procedure

  - by Josh Young

  I have a stored procedure that retrieves SQL queries as text and executes the statements using sp_executesql. Each of the dynamic queries is a count query in that it only returns the number of records found (select COUNT(id) from...). I am looping through a set of SQL queries stored as text and building a table variable out of the results. At the end, I am selecting all the results from the table variable as the result set that I want returned from the stored procedure. However, when I execute the stored procedure, I am naturally getting multiple result sets (one for each of the dynamic queries and one for the final select.) Is there any way I can suppress the results of a select statement executed through sp_executesql? I have found answers that reference storing the results in a temp table, but I don't have control of the query text that I am running so I can't change it to select into anything. Please help. Thank you for your time.

• Implementing zoom on a fixed point, javascript/canvas

  - by csiz

  I want to implement zooming on the mouse pointer with the mouse wheel. That is scaling the image while the point under the mouse pointer stays fixed. Here is my code, which doesn't work very well var scala = 1 + event.wheelDelta / 1000; canvas.context.translate(-canvas.mouse.x * ( scala - 1 ) / canvas.scale,-canvas.mouse.y * ( scala - 1 ) / canvas.scale); canvas.context.scale(scala,scala); canvas.scale *= scala; //canvas.scale is my variable that is initially set to 1. //canvas.mouse is my variable that represents the mouse position relative to the canvas

• Is it wise to rely on default features of a programming language?

  - by George Edison

  Should I frequently rely on default values? For example, in PHP, if you have the following: <?php $var .= "Value"; ?> This is perfectly fine - it works. But what if assignment like this to a previously unused variable is later eliminated from the language? (I'm not referring to just general assignment to an unused variable.) There are countless examples of where the default value of something has changed and so much existing code was then useless. On the other hand, without default values, there is a lot of code redundancy. What is the proper way of dealing with this?

• Flexible string handling in Visual Studio 2008 C++

  - by David

  I'm slowly starting to get the hang of the _T stuff in Visual Studio 2008 c++, but a few things still elude me. I can see the benefit of the flexibility, but if I can't get the basics soon, I think I'll go back to the standard way of doing this - much less confusing. The idea with the code below is that it scans the parameters for -d and then stores the text that follows that in the string variable fileDir. It also ignores any other parameters. Any help is appreciated. //Console application Parameters::Parameters(int argc, _TCHAR* argv[]) { _Tstring fileDir; // Is there some kind of _t variable to use here for a string? for (int i = 0; i < argc; i = i + 1) { if (_tccmp(argv[i], _T("-d")) == 0) // this appeared to accept anything starting with - { i = i + 1; fileDir = argv[i] } } _tprintf("Parameter value found: %s\n", fileDir); }

• 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?

• another file_exists with special chars problem

  - by Camran

  I have some folders with special characters in their names. I run currently at a test-computer with Windows OS, but later I will use LINUX. My problem is that the folders with special chars in their names cannot be recognized somehow. ex: file_exists('../Bilar/27733691_1.jpg') // TRUE file_exists('../Båtar/27733691_1.jpg') // FALSE because of the special char in folder name... How should I solve this? I plan to run LINUX in the future when website is online... would that matter? Please explain thoroughly because I am a newb at this Thanks

• conditional while loop in php?

  - by julio

  I'm pretty sure there's an obvious answer for this-- hoping someone can help me-- I need to do a PHP while loop, but only if a variable is true. And I can't really put the while loop in an "if" statement, which seems like the obvious thing to do, since the code block is huge and it would be ugly and confusing. Do I need to break out the code in the loop into a function, or is there an easier way to deal with this? Here's the basic idea: if(condition){ while(another_condition){ //huge block of code loops many times } } else { // huge block of code runs once } I want the huge block of code to execute regardless of the state of the condition variable-- but only to execute once if condition is false, and execute for as long as another_condition is true if condition is true. Hope that's clear! The following code doesn't work, but gives an idea of what I want to accomplish: if(condition){ while(another_condition){ } // huge block of code if (condition){ } } // closes the while loop-- obviously throws an error though! thanks in advance.

• What environment variables available while starting the script using init.d boot process

  - by raj_arni

  My problem is like this (OS is Sun Solaris): 1) At the boot time I want to start a process using a specific script. I am doing this by putting this script in /etc/init.d (and following other K and S rules) 2) The program which will be called by the script is located at $HOME/xxx/yyy location. 4) I am using 'su - {myuser} -c "{full path of the program}"' in order to execute the script as {myuser} 3) I dont want to hardcode the value of $HOME in the script but want to use the $HOME env variable only. How can I get this $HOME env variable in the shell script? Also what other variables will be available to me?

• PHP export to text file - Only saving first line.

  - by wertz8090

  I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.

• What is the standard way of using a sitemap with pages that require specific information passed to t

  - by Mike

  Hi, I have a website for which many pages rely on information passed to them (usually in the form of a querystring) or on a session variable. When making a web application, how do you normally handle these particular pages in regards to the sitemap? If you're using the standard ASP.NET menu control, it will render the node on the menu and if you click it, you could get an exception stating that a session variable doesn't exist (if it hasn't been created yet). For example, if you're making a user management area: All of these nodes get rendered, but I don't want the user to click on edit user or delete user without specifying someone to edit or delete. Any tips or suggestions would be greatly appreciated.

• Save or update for FK relationship Sqlalchemy

  - by Alex

  I've googled, but haven't been able to find the answer to this seemingly simple question. I have two relations, a customer and an order. Each order is associated to a single cusomter, and therefore has a FK relationship to the customer table. The customer relation only stores customer names, and I have set a unique constraint on the customer table barring duplicate names. Let's say I create a new order instance and set a customer for the order. Something like: order_instance.customer = Customer("customer name") When I save the order instance, SqlAlchemy will complain if a customer with this name already exists in the customer table. How do I specify to SqlAlchemy to insert into the customer table if a customer with this name doesn't already exist, or just ignore (or even update) to the customer relation? I don't really want to have to check each time if a customer with some name already exists...

• Can you set a form field value with PHP?

  - by dcp3450

  I use the $_GET function to pull a value with php from the url (http:..../index.html?variable=value), basic stuff. However, I need to use that value in my form. Typically, I would set <?php echo 'value="'.$variable.'"' ; ?> or something to that effect. However, I can't use php inside my form using the editor I'm working with. Can I set a value in the form without using PHP in my form? If so, how?

• Javascript Phone Swap

  - by Batfan

  I've been trying to find a way to do this but, have not found many resources that specifically relate to this situation. I need a javascript (can make use of Jquery if need be) to swap phone numbers on a site. 2 numbers would be specified. One would show on the site by default. The script needs to be able to create a cookie and do this by recognizing a value in the URL string. For Example: http://www.site.com/index.html?value= '?value=' would be the value. This URL (with the additional variable) would bring the user to the same site but, the variable in the string would set the cookie and display a different number. The default number would not be displayed again until the cookies were removed. Due to the situation with my server, I cannot make use of PHP ( I know, that would make things alot easier :P ) Any help would be greatly appreciated.

• Correct use of a "for...in" loop in javascript?

  - by jnkrois

  Hello everybody, before I ask my question I wanted to let everybody know that I appreciate the fact that there's always somebody out there willing to help, and on my end I'll try to give back to the community as much as I can. Thanks Now, I would like to get some pointers as to how to properly take advantage of the "for...in" loop in JavaScript, I already did some research and tried a couple things but it is still not clear to me how to properly use it. Let's say I have a random number of "select" tags in an HTML form, and I don't require the user to select an option for all of them, they can leave some untouched if they want. However I need to know if they selected none or at least one. The way I'm trying to find out if the user selected any of them is by using the "for...in" loop. For example: var allSelected = $("select option:selected"); var totalSelected = $("select option:selected").length; The first variable produces an array of all the selected options. The second variable tells me how many selected options I have in the form (select tags could be more than one and it changes every time). Now, in order to see if any has been selected I loop through each element (selected option), and retrieve the "value" attribute. The default "option" tag has a value="0", so if any selected option returns a value greater than 0, I know at least one option has been selected, however it does not have to be in order, this is my loop so far: for(var i = 0; i < totalSelected; i++){ var eachOption = $(allSelected[i]).val(); var defaultValue = 0; if(eachOption == defaultValue){ ...redirect to another page }else if(eachOption > defaultValue){ ... I display an alert } } My problem here is that as soon as the "if" matches a 0 value, it sends the user to the next page without testing the rest of the elements in the array, and the user could have selected the second or third options. What I really want to do is check all the elements in the array and then take the next action, in my mind this is how I could do it, but I'm not getting it right: var randomValue = 25; for(randomValue in allSelected){ var found = true; var notFound = false if(found){ display an alert }else{ redirect to next page } } This loop or the logic I'm using are flawed (I'm pretty sure), what I want to do is test all the elements in the array against a single variable and take the next action accordingly. I hope this makes some sense to you guys, any help would be appreciated. Thanks, JC

• Where best to instantiate and close a Silverlight-enabled WCF Service from the Silverlight app?

  - by Yttrium

  When using a Silverlight-enabled WCF service, where is the best place to instantiate the service and to call the CloseAsync() method? Should you say, instantiate an instance each time you need to make a call to the service, or is it better to just instantiate an instance as a variable of the UserControl that will be making the calls? Then, where is it better to call the CloseAsync method? Should you call it in each of the "someServiceCall_completed" event methods? Or, if created as a variable of the UserControl class, is there a single place to call it? Like a Dispose method, or something equivalent for the UserControl class. Thanks, Jeff
