Array manipulation

Yashpal — Wed, 06 Oct 2010 06:52:27 +0000

i want to create a 10×10 matrix(with user input)

for e.g., i have given a small sample of 2×2 matrix and below is the description regarding what manipulation i want to do.

say for e.g my matrix is
0.76 1
0 0.3

now what i want to do is that, whenever the value in the matrix is greater than 0.25, i want to print 1 and if it is less than 0.25 than i want to print 0 and if it is 0 or 1 then let it be as it is….
so the answer for my above matrix should be

1 1
0 0

Is it possible to assign more than one form element to one php variable?

PatOswalt — Sat, 13 Mar 2010 19:46:12 +0000

I have an HTML form file and a PHP file that are supposed to interact with eachother to save information from the form to a contactlist text file. I had it working fine and it has been turned it, but started playing with it and now have a question.

Is it possible to assign more than one form element to one php variable? I want my form to have a specific text field for the area code, the prefix and the line number and then want to combine those three field into one variable. This is not a requirement for my class, I’m just wanting to see how much I can do with this. Here is my html code below:

Telephone Directory Input

New Directory Listing

Add New Listing

Retrieve Contact List

Here is my PHP code:


    
    
    
        Save Directory
    
     
    

        You must completely fill out the form.  Please use your browser's Back button to return to the form.";

        else 
        //creating, writing and saving to the text file.
        $NewContact = 'contactlist.txt';
        $Contact = fopen($NewContact, 'a+');
        $output ="n $LastName n";
        $output .="n $FirstName n";
        $output .="n $StreetAdd n";
        $output .="n $City n";
        $output .="n $State n";
        $output .="n $ZipCode n";
        $output .="n $AreaCode n";
        $output .="n $PhoneNum['Prefix']['LineNumb'] n";//this is where the error in pointing to.
        echo "New Contact Saved Successfully!";
        fwrite($Contact, $output);
        fclose($Contact);

    // Split a string into an index array
        $Contacts = "$LastName;$FirstName;$StreetAdd;$City;$State;$ZipCode;$AreaCode;$PhoneNum";
        $ContactsArray = explode(";", $Contacts);
        echo "
Contact List

";
        for($i=0; $i";
         }
    // Sort an index array
        sort($ContactsArray);
        echo "
Sorted Contact List

";
        foreach($ContactsArray as $Contacts) {
           echo "$Contacts
";
         }
    
        ?>

Parsing error in a class project. Can’t figure it out

PatOswalt — Thu, 11 Mar 2010 18:21:30 +0000

This is a project for a class. I’m unable to figure it out and I’m at my wits end. I’m not asking for someone to do the project to me, just tell me where my coding is wrong. My html form is correct. I just placed in on here for a reference. My php code seems to work until I get to the // Split a string into an index array. Any help would be greatly appreciated.

When I try to run the program through WAMP I get an error:

Parse error: parse error in C:wampwwwOswaltPatricia_Unit4AssignmentSaveDirectory.php on line 53

Line 53 is:
$Contacts = “$LastName;$FirstName;$StreetAdd;$City;$State;$ZipCode;$AreaCode;$PhoneNum”;

Vb.Net Image List

Surfdog — Fri, 30 May 2008 23:53:27 +0000

I am Trying to build a game that uses arrays to select an image from an image list. when i run the game, i get an image in the image box, but it keeps cycling through all three options.

the code so far is:

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim flagRight As Integer = 0
Dim flagLeft As Integer = 0
Dim I, J As Integer
Do Until flagRight = 1
I = Int(Rnd() * 3)
picRight.Image = imlRight.Images(I)
flagRight = 1
Loop
Do Until flagLeft = 1
J = Int(Rnd() * 3)
picLeft.Image = imlLeft.Images(J)
picRight.Visible = True
flagLeft = 1
Loop

Can anyone help

thanks a lot
