  • object-oriented question

    - by user522962
    I am attempting to put all my database connections in 1 php file, rather than in each of my individual php pages. I have the following: //conn.php: <?php class conn { var $username = "name"; var $password = "password"; var $server = "localhost"; var $port = "3306"; var $databasename = "db"; var $tablename = "tablename"; var $connection; public function getConnected() { $this->connection = mysqli_connect( $this->server, $this->username, $this->password, $this->databasename, $this->port ); } } ?> // file.php: <?php require_once("conn.php"); class myClass{ public function con() { $conn = new conn(); $conn->getConnected(); } public function myF() { $stmt = mysqli_prepare($conn->connection, "SELECT * FROM $conn->tablename"); mysqli_stmt_execute($stmt); } } ?> I then call this as follows: $myNew = new myClass(); $myNew-con(); $myNew-myF(); When I call this, I get the following error: Undefined property: myClass::$connection What am I doing wrong?

  • Amazon EC2 pricing question

    - by Industrial
    Hi everyone, I took my first step today on working with cloud servers and chosed Amazon EC2 for this project. Since I am a bit of a newcomer on this, I didn't fully understand their pricing: What happens when a instance is idling with no connections being made. Does it still cost us money? It would be sad to have instances idling and costing us money when we do not use them... Thanks a lot!

  • Beginners PHP / mySQL question

    - by Reg H
    I'm brand new to PHP & MySQL, and one function I'm creating needs to access a large table or database. I've created the database and it's currently in a MySQL table, which I'm accessing with no problem. The table is 11,000 rows in length, with 8 columns (all text less than 8 characters long) - it's static, and will never change. Without getting too particular, my users will hit a button which will trigger scripts to access the data, say 500 times or more. So in general would it be better practice to include all of this data in a big 'switch' or 'if... then' conditional right in my scripts, rather than opening and accessing the database connection hundreds, or maybe even thousands of times? It just seems like that might be a bottleneck waiting to happen. Thanks!

  • android question about service and the method onstartcommand

    - by user516883
    In a service class there is a method to start the service. If that service gets done executing does it runs onstartcommand from the beginning? Is onstartcommand sorta like a loop as long as the service is running. For example i have onstartcommand { int x = 0; if(x == 0){ } else{ } } After that is complete does it run it again. If you know that answer please explain. I have read google explanation of services and it did not explain that part very well. Is onstartcommand sorta like a loop as long as the service is runnning

  • WIN32 API question - Looking for answer asap

    - by Lalit_M
    We have developed a ASP.NET web application and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. Has anyone seen this behavior with the Win32 LogonUser method? Does anyone know how to disable this behavior? I have tried LOGON32_LOGON_BATCH but it was giving an error 1385 in authentication user. I need either of the solution 1) Is there any way to stop the folder generation. 2) What parameter I need to pass this to work? Thanks

  • Question about inserting/updating rows with MS SQL (ASP.NET MVC)

    - by Alex
    I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today But what if the row doesn't exist? I'd have to use INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today) How can I check if the row exists or not? Is there any way different from doing the COUNT(*)? If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.

  • c# event and delegate question

    - by user359562
    I want to detach the custom event but could not detach. Please find below I am using -= to detach the event. I assume after this, TextChanged2 method should not be invoked as I have unregistered the event. Let me know if my understanding is wrong. public delegate void TextChangedEventHandler1(object sender, TextBoxargs ta); public event TextChangedEventHandler1 TextChanged1; private void textBox1_TextChanged(object sender, EventArgs e) { this.TextChanged1 -= new TextChangedEventHandler1(TextChanged2); TextChanged2(sender, e); } public void TextChanged2(object sender, EventArgs e) { textBox1.Text = textBox1.Text.ToUpper(); }

  • Docmd.TransferText question

    - by every_answer_gets_a_point
    b'h i will be programmatically importing a text file into a table. i have saved the import steps. i will use this: DoCmd.TransferText(TransferType, SpecificationName, TableName, FileName, HasFieldNames, HTMLTableName, CodePage) to do the import. this is what SpecificationName means: Specification Name The specification name for the set of options that determines how a text file is imported, exported, or linked. For a fixed-width text file, you must either specify a specification name or use a schema.ini file, which should be stored in the same directory as the imported, linked, or exported text file. i do need a specific specification; however i do not know how to specify one. when i manually imported a table, i did save the specifications for my import, however i do not know how to call this in the TransferText. does anyone know how to specify SpecificationName ?

  • question on reverse array

    - by davit-datuashvili
    we know algorithm how reverse array of n integers for (int i=0;i<n/2;i++){ swap(a[i],a[n-1-i]): } is this method better according the speed of algorithm or not because swap using xor is more fast then in other method here is code public class swap { public static void main(String[]args){ int a[]=new int[]{2,4,5,7,8,11,13,12,14,24}; System.out.println(" array at the begining:"); for (int i=0;i<a.length;i++){ System.out.println(a[i]); } for (int j=0;j<a.length/2;j++){ a[j]^=a[a.length-1-j]; a[a.length-1-j]^=a[j]; a[j]^=a[a.length-1-j]; } System.out.println("reversed array:"); for (int j=0;j<a.length;j++){ System.out.println(a[j]); } } } Result: array at the begining: 2 4 5 7 8 11 13 12 14 24 reversed array: 24 14 12 13 11 8 7 5 4 2
