  • Dymanic if statement evaluation problem with string comparison

    - by Mani
    I tried the example given in http://forums.sun.com/thread.jspa?threadID=780576&tstart=67605 to create if statement dynamically. But it is not working fine. Instead of using "age" variable as integer, i have used string in the below example. I am getting "fail" as answer instead of "success". Can anyone help me? / To change this template, choose Tools | Templates and open the template in the editor. / import java.lang.reflect.*; import bsh.Interpreter; public class Main { public static String d; public static void main(String args[]) { try { String age = "30"; String cond = "age==30"; Interpreter i = new Interpreter(); i.set("age", age); System.out.println(" sss" + i.get("age")); if((Boolean)i.eval(cond)) { System.out.println("success"); } else { System.out.println("fail"); } } catch (Throwable e) { System.err.println(e); } } } Thanks, Mani

  • Nicely representing a floating-point number in python

    - by dln385
    I want to represent a floating-point number as a string rounded to some number of significant digits, and never using the exponential format. Essentially, I want to display any floating-point number and make sure it “looks nice”. There are several parts to this problem: I need to be able to specify the number of significant digits. The number of significant digits needs to be variable, which can't be done with with the string formatting operator. I need it to be rounded the way a person would expect, not something like 1.999999999999 I've figured out one way of doing this, though it looks like a work-round and it's not quite perfect. (The maximum precision is 15 significant digits.) >>> def f(number, sigfig): return ("%.15f" % (round(number, int(-1 * floor(log10(number)) + (sigfig - 1))))).rstrip("0").rstrip(".") >>> print f(0.1, 1) 0.1 >>> print f(0.0000000000368568, 2) 0.000000000037 >>> print f(756867, 3) 757000 Is there a better way to do this? Why doesn't Python have a built-in function for this?

  • Modify shell script to monitor/ping multiple ip addresses

    - by Alex
    Alright so I need to constantly monitor multiple routers and computers, to make sure they remain online. I have found a great script here that will notify me via growl(so i can get instant notifications on my phone) if a single ip cannot be pinged. I have been attempting to modify the script to ping multiple addresses, with little luck. I'm having trouble trying to figure out how to ping a down server while the script keeps watching the online servers. any help would be greatly appreciated. I haven't done much shell scripting so this is quite new to me.

  • Publish failed using Ant publisher (Eclipse/datanucleus).

    - by aronp
    Dear All, I am being driven mad the following (apparently hard) error from eclipse. Publish failed using Ant publisher Resource is out of sync with the file system: '/MyServlet/build/classes/com/inver/hotzones/database/BaseNetworkData.class'. I have seen comments on similar errors where refreshing eclipses view of the project helps but it is not helping me. Have tried cleaning the project, removing it from the webserver, deleting war files but cant seem to clear it. I have reset my TMPDIR variable so that it uses a directory on the same filesystem as that appeared to be another possible cause. The error occurs on classes which have been enhanced by datanuculeus. I have auto-enhance on the project. The other references to this problem indicate that it is due to Eclipses view of the project being out of step with the filesystem, and I am guessing that this has something to do with thedata nucleus enhancement. Any ideas? Thanks. I am using Eclipse 3.5.2 with latest datanucleus pluggins.

  • Why Sql not bringing back results unless I set varchar size?

    - by Tom
    I've got an SQL script that fetches results based on the colour passed to it, but unless I set the size of the variable defined as a varchar to (50) no results are returned. If I use: like ''+@Colour+'%' then it works but I don't really want to use it in case it brings back results I don't need or want. The column FieldValue has a type of Varchar(Max) (which can't be changed as this field can store different things). It is part of aspdotnetstorefront package so I can't really change the tables or field types. This doesn't work: declare @Col VarChar set @Col = 'blu' select * from dbo.MetaData as MD where MD.FieldValue = @Colour But this does work: declare @Col VarChar (50) set @Col = 'blu' select * from dbo.MetaData as MD where MD.FieldValue = @Colour The code is used in the following context, but should work either way <query name="Products" rowElementName="Variant"> <sql> <![CDATA[ select * from dbo.MetaData as MD where MD.Colour = @Colour ]]> </sql> <queryparam paramname="@ProductID" paramtype="runtime" requestparamname="pID" sqlDataType="int" defvalue="0" validationpattern="^\d{1,10}$" /> <queryparam paramname="@Colour" paramtype="runtime" requestparamname="pCol" sqlDataType="varchar" defvalue="" validationpattern=""/> </query> Any Ideas?

  • Efficient splitting of elements in a field

    - by Gary
    I have a field in a text file exported from a database. The field contains addresses but sometimes they are quite long and the database allows them to contain multiple lines. When exported, the newline character gets replaced with a dollar sign like this: first part of very long address$second part of very long address$third part of very long address Not every address has multiple lines and no address contains more than three lines. The length of each line is variable. I'm massaging the data for import into MS Access which is used for a mailmerge. I want to split the field on the $ sign if it's there but if the field only contains 1 line, I want to set my two extra output fields to a zero length string so that I don't wind up with blank lines in the address when it gets printed. I have an awk file that's working correctly on all the other data in the textfile but I need to get this last bit working. I tried the below code. Aside from the fact that I get a syntax error at the else, I'm not sure this is a good way to do what I want. This is being done with gawk on Windows. BEGIN { FS = "|" } $1 != "HEADER" { if ($6 ~ /\$/) split($6, arr, "$") address = arr[1] addresstwo = arr[2] addressthree = arr[3] addressLength = length(address) addressTwoLength = length(addresstwo) addressThreeLength = length(addressthree) else { address = $6 addressLength = length($6) addresstwo = "" addressTwoLength = length(addresstwo) addressthree = "" addressThreeLength = length(addressthree) } printf("%*s\t%*s\t\%*s\n", addressLength, address, addressTwoLength, addresstwo, addressThreeLength, addressthree) }

  • C++ Returning a Reference

In both the cases compiler does not even throws the Warning: returning address of local variable or temporary as I am returning a reference. #include <iostream> #include <string> using namespace std; double &getDouble(){ double h = 46.5; double &hours = h; return hours; } string &getString(){ string str = "Devil Jin"; string &refStr = str; return refStr; } int main(){ double d = getDouble(); cout << "Double = " << d << endl; string str = getString(); cout << "String = " << str.c_str() << endl; return 0; } Output: $ ./a.exe Double = 46.5 String =

  • Calculating bounding box a certain distance away from a lat/long coordinate in Java

    - by Bryce Thomas
    Given a coordinate (lat, long), I am trying to calculate a square bounding box that is a given distance (e.g. 50km) away from the coordinate. So as input I have lat, long and distance and as output I would like two coordinates; one being the south-west (bottom-left) corner and one being the north-east (top-right) corner. I have seen a couple of answers on here that try to address this question in Python, but I am looking for a Java implementation in particular. Just to be clear, I intend on using the algorithm on Earth only and so I don't need to accommodate a variable radius. It doesn't have to be hugely accurate (+/-20% is fine) and it'll only be used to calculate bounding boxes over small distances (no more than 150km). So I'm happy to sacrifice some accuracy for an efficient algorithm. Any help is much appreciated. Edit: I should have been clearer, I really am after a square, not a circle. I understand that the distance between the center of a square and various points along the square's perimeter is not a constant value like it is with a circle. I guess what I mean is a square where if you draw a line from the center to any one of the four points on the perimeter that results in a line perpendicular to a side of the perimeter, then those 4 lines have the same length.

  • APS.NET MVC Ajax: Passing a IList from the View to the Controller

    - by Bpimenta
    I need to pass the grid rows from the view to the controller using POST. The idea is to pass an IList of objects (people) that have the following structure: String Name String Address String ID I want to read the data from the JQGrid and pass it to the controller to fill the IList. I'm trying to build the data object to pass through the Ajax data parameter. Here is the Javascript code: $("#saveButton").click( function() { var returnData = '{'; var existingIDs = $('#listPeople').getDataIDs(); if (idsPeople.length > 0) { for (i=0;i<idsPeople.length;i++) { //Trying to build the obejct data ret = ret + '"people['+ i +'].Name":' $('#listPeople').getRowData(idsPeople[i]).Name + ','; ret = ret + '"people['+ i +'].Address":' $('#listPeople').getRowData(idsPeople[i]).Address+ ','; ret = ret + '"people['+ i +'].Id":' $('#listPeople').getRowData(idsPeople[i]).Id+ ','; //If it has more than one element if (idsPeople.length>1 && (i+1)<idsPeople.length) { ret = ret + ','; } } } ret = ret + '}'; My Ajax function for sending: var url_all = '<%=Url.Action("SaveData") %>; $.ajax({ type: "POST", url: url_all, data: ret, dataType: "json", success: function(){ alert("OK"); }, error: function(){ alert("Error: check SaveData"); } }); My controller: public ActionResult SaveData(IList<PeopleHeader> people){ // using debug to know if "people" variable has any values return Json(true); } The problem I'm getting is an error: "System.NotSupportedException: Fixed size collection", and no data is being delivered. I think my problem relies on creating the object... is there any simpler way of doing this procedure? Thanks in advance,

  • Read HTML file into email

    - by cast01
    Ive written a script to send html emails and all works well. I have the email stored in a separate HTML file which is then read in usin a while loop and fgets(). However, i want to be able to pass variables into the html. For example, in a html file i may have something like.. <body> Dear Name <br/> Thank you for your recent purhcase </body> and i read this into a string like so $file = fopen($filename, "r"); while(!feof($file)) { $html.= fgets($file, 4096); } fclose ($file); I want to be able to replace "Name" in the html file by a variable and im not entirely sure on the best way to do this. I could always make my own tag and then use regex to replace that with the name once ive read the file into the string, but im wondering if there is a better/easier method to do this. (On a side note, if anyone knows whether its better to use file_get_contents instead of multiple calls to fgets, id be interested to know)

  • Extension methods conflict

    - by Yochai Timmer
    Lets say I have 2 extension methods to string, in 2 different namespaces: namespace test1 { public static class MyExtensions { public static int TestMethod(this String str) { return 1; } } } namespace test2 { public static class MyExtensions2 { public static int TestMethod(this String str) { return 2; } } } These methods are just for example, they don't really do anything. Now lets consider this piece of code: using System; using test1; using test2; namespace blah { public static class Blah { public Blah() { string a = "test"; int i = a.TestMethod(); //Which one is chosen ? } } } I know that only one of the extension methods will be chosen. Which one will it be ? and why ? How can I choose a certain method from a certain namespace ? Edit: Usually I'd use Namespace.ClassNAME.Method() ... But that just beats the whole idea of extension methods. And I don't think you can use Variable.Namespace.Method()

  • With PascalMock how do I mock a method with an untyped out parameter and an open array parameter?

    - by Oliver Giesen
    I'm currently in the process of getting started with unit testing and mocking for good and I stumbled over the following method that I can't seem to fabricate a working mock implementation for: function GetInstance(const AIID: TGUID; out AInstance; const AArgs: array of const; const AContextID: TImplContextID = CID_DEFAULT): Boolean; (TImplContextID is just an alias for Integer) I thought it would have to look something like this: function TImplementationProviderMock.GetInstance( const AIID: TGUID; out AInstance; const AArgs: array of const; const AContextID: TImplContextID): Boolean; begin Result := AddCall('GetInstance') .WithParams([@AIID, AContextID]) .ReturnsOutParams([AInstance]) .ReturnValue; end; But the compiler complains about the .ReturnsOutParams([AInstance]) saying "Bad argument type in variable type array constructor.". Also I haven't found a way to specify the open array parameter AArgs at all. Also, is using the @-notation for the TGUID-typed parameter the right way to go? Is it possible to mock this method with the current version of PascalMock at all?

  • Can't get data with spaces into the database from Ajax POST request

    - by J Jones
    I have a real simple form with a textbox and a button, and my goal is to have an asynchronous request (jQuery: $.ajax) send the text to the server (PHP/mysql a la Joomla) so that it can be added to a database table. Here's the javascript that is sending the data from the client: var value= $('#myvalue').val(); $.ajax( { type: "POST", url: "/administrator/index.php", data: { option: "com_mycomponent", task: "enterValue", thevalue: value, format: "raw"}, dataType: "text", success: reportSavedValue } ); The problem arises when the user enters text with a space in it. The $_POST variable that I receive has all the spaces stripped out, so that if the user enters "This string has spaces", the server gets the value "Thisstringhasspaces". I have been googling around, and have found lots of references that I need to use encodeURIComponent. So I have tried it, but now the value that I get from $_POST is "This20string20has20spaces". So it appears to be encoding it the way I would expect, only to have the percent signs stripped instead of the spaces, and leaving the hex numbers. I'm really confused. It seems that this sort of question is asked and answered everywhere on the web, and everywhere encodeURIComponent is hailed as the silver bullet. But apparently I'm fighting a different breed of lycanthrope. Does anyone have any suggestions?

  • Why do Firefox and Opera ignore max-width inside of display: table-cell?

    - by brad
    The following code displays correctly in Chrome or IE (the image is 200px wide). In Firefox and Opera the max-width style is ignored completely. Why does this happen and is there a good work around? Also, which way is most standards compliant? Note One possible work around for this particular situation is to set max-width to 200px. However, this is a rather contrived example. I'm looking for a strategy for a variable width container. <!doctype html> <html> <head> <style> div { display: table-cell; padding: 15px; width: 200px; } div img { max-width: 100%; } </style> </head> <body> <div> <img src="http://farm4.static.flickr.com/3352/4644534211_b9c887b979.jpg" /> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec facilisis ante, facilisis posuere ligula feugiat ut. Fusce hendrerit vehicula congue. at ligula dolor. Lorem ipsum dolor sit amet, consectetur adipiscing elit. leo metus, aliquam eget convallis eget, molestie at massa. </p> </div> </body> </html> [Update] As stated by mVChr below, the w3.org spec states that max-width does not apply to inline elements. I've tried using div img { max-width: 100%; display: block; }, but it does not seem to correct the issue.

  • Flex wordwrap issue with multiple text instances

    - by Craig Myles
    Hi, I have a scenario where I want to dynamically add words of text to a container so that it forms a paragraph of text which is wrapped neatly according to the size of the parent container. Each text element will have differing formatting, and will have differing user interaction options. For example, imagine the text " has just spoken out about ". Each word will be added to the container one at a time, at run time. The username in this case would be bold, and if clicked on will trigger an event. Same with the news article. The rest of the text is just plain text which, when clicked on, would do nothing. Now, I'm using Flex 3 so I don't have access to the fancy new text formatting tools. I've implemented a solution where the words are plotted onto a canvas, but this means that the words are wrapped at a particular y position (an arbitrary value I've chosen). When the container is resized, the words still wrap at that position which leaves lots of space. I thought about adding each text element to an Array Collection and using this as a datasource for a Tile List, but Tile Lists don't support variable column widths (in my limited knowledge) so each word would use the same amount of space which isn't ideal. Does anyone know how I can plot words onto a container so that I can retain formatting, events and word wrapping at paragraph level, even if the container is resized?

  • How to make UIButton work like Launcher in SpringBoard, when pressed for long timeinterval

    - by KayKay
    In my ViewController I am using UIButton which triggers some action when touchedUpInside. Upto here no problem, but i also want to add another action for touchDown event. More precisely i dont have an idea how to add that action to which event, that will work the same as when App-Icon is pressed longer in springboard which causes springboard enter in editing mode.Actually what i want is : when this button is kept holding for ,say about 2 seconds it will pop-up an alertView without touch being heldUp (with finger is still on button). I have tried with 2 NSdate difference, one of which is allocated when touchedDown and other when touchUpInside. Its working and popping alert,but only after touchedUpInside. I want it to show alert without touch being removed. Here is the code. (IBAction)touchedDown:(id)sender { momentTouchedDown = [[NSDate alloc] init];//class variable NSLog(@"touched down"); } - (IBAction)touchUpInside:(id)sender { NSLog(@"touch lifted Up\n"); NSDate *momentLifted = [[NSDate alloc] init]; double timeInterval = [momentLifted timeIntervalSinceDate:momentTouchedDown]; NSLog(@"time lifted = %@, time down = %@, time diff = %@", momentLifted, momentTouchedDown, [NSString stringWithFormat:@"%g",timeInterval]); [momentLifted release]; if(timeInterval > 2.0) { NSLog(@"AlertBox has been fired"); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Yes" message:@""//msg delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK" , nil]; [alert show]; [alert release]; } } Please provide me an insight..thanks for help in advance.

  • strange behavior in python

    - by fsm
    The tags might not be accurate since I am not sure where the problem is. I have a module where I am trying to read some data from a socket, and write the results into a file (append) It looks something like this, (only relevant parts included) if __name__ == "__main__": <some init code> for line in file: t = Thread(target=foo, args=(line,)) t.start() while nThreads > 0: time.sleep(1) Here are the other modules, def foo(text): global countLock, nThreads countLock.acquire() nThreads += 1 countLock.release() """connect to socket, send data, read response""" writeResults(text, result) countLock.acquire() nThreads -= 1 countLock.release() def writeResults(text, result): """acquire file lock""" """append to file""" """release file lock""" Now here's the problem. Initially, I had a typo in the function 'foo', where I was passing the variable 'line' to writeResults instead of 'text'. 'line' is not defined in the function foo, it's defined in the main block, so I should have seen an error, but instead, it worked fine, except that the data was appended to the file multiple times, instead of being written just once, which is the required behavior, which I got when I fixed the typo. My question is, 1) Why didn't I get an error? 2) Why was the writeResults function being called multiple times?

  • UIViewController remaining

    - by Guy
    Hi Guys. I have a UIViewController named equationVC who's user interface is being programmatically created from another NSObject class called equationCon. Upon loading equationVC, a method called chooseInterface is called from the equationCon class. I have a global variable (globalVar) that points to a user defined string. chooseInterface finds a method in the equationCon class that matches the string globalVar points to. In this case, let's say that globalVar points to a string that is called "methodThatMatches." In methodThatMatches, another view controller needs to show the results of what methodThatMatches did. methodThatMatches creates a new equationVC that calls upon methodThatMatches2. As a test, each method changes the color of the background. When the application starts up, I get a purple background, but as soon as I hit backwards I get another purple screen, which should be yellow. I do not think that I am release the view properly. Can anyone help? -(void)chooseInterface { NSString* equationTemp = [globalVar stringByReplacingOccurrencesOfString:@" " withString:@""]; equationTemp = [equationTemp stringByReplacingOccurrencesOfString:@"'" withString:@""]; SEL equationName = NSSelectorFromString(equationTemp); NSLog(@"selector! %@",NSStringFromSelector(equationName)); if([self respondsToSelector:equationName]){ [self performSelector:equationName]; } } -(void)methodThatMatches{ self.equationVC.view.backgroundColor = [UIColor yellowColor]; [setGlobalVar:@"methodThatMatches2"]; EquationVC* temp = [[EquationVC alloc] init]; [[self.equationVC navigationController] pushViewController:temp animated:YES ]; [temp release]; } -(void)methodThatmatches2{ self.equationVC.view.backgroundColor = [UIColor purpleColor]; }

  • Applying policy based design question

    - by Arthur
    I've not read the Modern C++ Design book but have found the idea of behavior injection through templates interesting. I am now trying to apply it myself. I have a class that has a logger that I thought could be injected as a policy. The logger has a log() method which takes an std::string or std::wstring depending on its policy: // basic_logger.hpp template<class String> class basic_logger { public: typedef String string_type; void log(const string_type & s) { ... } }; typedef basic_logger<std::string> logger; typedef basic_logger<std::wstring> wlogger; // reader.hpp template<class Logger = logger> class reader { public: typedef Logger logger_type; void read() { _logger.log("Reading..."); } private: logger_type _logger; }; Now the questing is, should the reader take a Logger as an argument, like above, or should it take a String and then instantiate a basic_logger as an instance variable? Like so: template<class String> class reader { public: typedef String string_type; typedef basic_logger<string_type> logger_type; // ... private: logger_type _logger; }; What is the right way to go?

  • memory alignment within gcc structs

    - by Mumbles
    I am porting an application to an ARM platform in C, the application also runs on an x86 processor, and must be backward compatible. I am now having some issues with variable alignment. I have read the gcc manual for __attribute__((aligned(4),packed)) I interpret what is being said as the start of the struct is aligned to the 4 byte boundry and the inside remains untouched because of the packed statement. originally I had this but occasionally it gets placed unaligned with the 4 byte boundary. typedef struct { unsigned int code; unsigned int length; unsigned int seq; unsigned int request; unsigned char nonce[16]; unsigned short crc; } __attribute__((packed)) CHALLENGE; so I change it to this. typedef struct { unsigned int code; unsigned int length; unsigned int seq; unsigned int request; unsigned char nonce[16]; unsigned short crc; } __attribute__((aligned(4),packed)) CHALLENGE; The understand I stated earlier seems to be incorrect as both the struct is now aligned to a 4 byte boundary, and and the inside data is now aligned to a four byte boundary, but because of the endianess, the size of the struct has increased in size from 42 to 44 bytes. This size is critical as we have other applications that depend on the struct being 42 bytes. Could some describe to me how to perform the operation that I require. Any help is much appreciated.

  • LINQDataSource and private columns

    - by fyjham
    Hey, I was trying to use a ListView bound to a LinqDataSource to insert to a table where I had a few columns private to the table class (Specifically password columns - only access I want to give outside the class is methods that generate the salt and encrypt the password to store it in 1 go). I gave this a few shots, but I didn't come up with anything I really liked... was wondering if anyone has a better way to do this. The methods I've found: Use the LinqDataSource inserting event and make the appropriate calls on e.NewObject. I don't really like this because it's so far removed from the actual input and there's no simple way to hold the password in the meantime other than a class variable set during the ListView's inserting event (Which works, but seems a little dodgy). Open up these properties and just ask everyone to use the appropriate static methods for encoding the passwords they pass in. I don't really like this cause I'd prefer that class to enforce data integrity rather than relying on all calling code doing it properly... I'm currently going with option #1, but I don't really like passing values between events using class variables like that (It just seems unstructured... even though I can guarantee the events will happen in the right order). Does anyone know a better way, or alternatively am I being too pedantic and one of the methods above is actually the right way to go? Thanks

    - by h2g2java
    I asked this at the GWT forum but I'm impatient for the answer and I seem to get rather good responses here. A html or jsp file is used to launch the xxx.nocache.js, which then decides which browser "permutation" to use. <head> <meta http-equiv="content-type" content="text/html;charset=UTF-8"> <title>xxx</title> <script type="text/javascript" language="javascript" src="xxx.nocache.js"></script> </head> In my case, I am using a jsp. When the JSP is executed, it discovers some conditions. I wish to pass these conditions as values to the GWT module being launched. The "elegant" GWT way to pass these values would be to persist them as request/memcache attributes and then have the GWT module perform RPC to retrieve those values. For example, the JSP discovers that the current user is Whoopy. Shouldn't I simply have the JSP generate javascript to store user = "Whoopy" as a top or namedframe level javascript variable and use JSNI within the module to retrieve the value for user? I have not tried it yet, but I would like to know how anyone might have done it without having to use RPC.

  • Convert templated parameter type to string

    - by wheaties
    I've got a small bit of DRY going on in code I and others have written that I'd like to reduce but I'm failing to figure out how to get it done. This is legacy COM code but it's interfering with the readability. I'd like to do the following: bool queryInterface<class T, class V>(T &_input, V &_output, Logger &_logger){ if( FAILED( _input->QueryInterface( &_output ) ) ){ _logger.error() << "Failed to Query Interface between " << MAGICHAPPENS<T>() << " and " << MAGICHAPPENS<V>(); return false; } if( _output == NULL ){ _logger.warn() << "Unable to Query Interface between " << MAGICHAPPENS<T>() << " and " << MAGICHAPPENS<V>(); return false; } } Wherein the "MAGICHAPPENS()" function would spit out the name of the variable type. Such that if "V" were a IQueryFilter I'd get back a string of "IQueryFilter." I can't think of any reasonable solution without having to write a bunch of template specializations totally defeating the point in the first place. Is there a way to write ANDMAGICHAPPENS?

  • How to add text to email sent from a php contact form

    - by JustStatic
    Hi all this is the PHP im using: <?php $name = $_POST['name']; $email = $_POST['email']; $phone = $_POST['phone']; $message = $_POST['message']; $formcontent=" From: $name \n Phone: $phone \n Message: $message"; $recipient = "[email protected]"; $subject = "Contact Form"; $mailheader = "From: $email \r\n"; mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); echo "Thank You!" . " -" . "<a href='contact.html' style='text-decoration:none; color:#ff0099;'> Return Home</a>"; ?> Its working perfectly fine but i would like there to be some text sent with this email that says "This is from your website" or something similar to tell the recipient that it isnt spam (my client isn't tech friendly and sees everything plain text as spam). I'm very new to PHP with nearly 0 knowledge and have no idea how to add something like that. I did have a go at making a new variable with the string inside and then include that in the: mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); line but with no success. Thanks for taking the time any help would be welcome.
