  • Linux tool to send raw data to a TCP server

    - by paul simmons
    Hi, I am aware that this is not a direct 'development' question but I need that info to test a development project, so I think someone could've hit similar problem. I will test a software that runs a TCP server and according to sent commands replies some answers. I will test the software and do not want to write code if it doesn't work well. So I want to send those commands and test drive the server software. How can I achieve this with a Linux box?

  • Why can't your switch statement data type be long Java?

    - by Fostah
    Here's an excerpt from Sun's Java tutorials: A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Classes and Inheritance) and a few special classes that "wrap" certain primitive types: Character, Byte, Short, and Integer (discussed in Simple Data Objects ). There must be a good reason why the long primitive data type is not allowed. Anyone know what it is?

  • handling matrix data in python

    - by Ovisek
    I was trying to progressively subtract values of a 3D matrix. The matrix looks like: ATOM 1223 ZX SOD A 11 2.11 -1.33 12.33 ATOM 1224 ZY SOD A 11 -2.99 -2.92 20.22 ATOM 1225 XH HEL A 12 -3.67 9.55 21.54 ATOM 1226 SS ARG A 13 -6.55 -3.09 42.11 ... here the last three columns are representing values for axes x,y,z respectively. now I what I wanted to do is, take the values of x,y,z for 1st line and subtract with 2nd,3rd,4th line in a iterative way and print the values for each axes. I was using: for line in map(str.split,inp): x = line[-3] y = line[-2] z = line[-1] for separating the values, but how to do in iterative way. should I do it by using Counter.

    - by poeschlorn
    Hi guys, it may be a nooby question, but I've never needed it before: I have several strings and I want to compare them to given ones... At first glance it would lead to a switch/case construction in what every available entry is checked. Is there a more elegant way to swap those strings as key/value datas? greets, poeschlorn

  • Android GPS data of Railway Stations of India

    - by user578098
    Hi, I want to make an android application that will intimate the users about the approaching railway stations in INDIA. For this I will use GPS (Location Manager etc) on Android. So far, I have not developed the applications using GPS, so I have little insight on the capabilities of Android API for this. I know, through the android API I can know the current location of the users through GPS and google API but can I know the location of nearby railway stations from Google API for India? Or can I know the latitude and longitude of all the Railway Stations so that I can pre-feed that in the applciation? Please help me in finding out the way.

  • MS Access Form - Horizontal Anchor Affecting Data Update

    - by nicholas
    Running Access 2007 with a databound form. The form Record Source is set to a query, and all fields in the form have a defined Control Source; nothing fancy, just field names. The form is a Single form with record navigation buttons which perform a "Next Record" and "Previous Record" actions. As I navigate the records the controls in the header update correctly. However, if I change a control Horizontal Anchor property to "Right" the fields no longer update on record navigation. This is observed for both text box and combo box controls. I can switch the anchoring back to "Left" and the updating works as it should. Is there some reason anchoring would affect a control updating of in an Access form? Or is this a bug that has been observed before? The only workaround I can think of is to assign the control text/value property in the form OnCurrent event, but this seems somewhat sloppy. Am I missing something here?

  • Data not entering the table

    - by Luke
    //loop through usernames to add to league table for ($i = 0; $i < count($user); $i++) { //set some new variables in an array $username = $user[$i]; $squad = $team[$i]; //add details to league table if ( $username != "Ghost") { $database->addUsersToLeagueTable($username, $squad); } } I use this code to add to the league table, the following is more code: function addUsersToLeagueTable($username, $squad) { $q = "INSERT INTO `$_SESSION[comp_name]` ( `user` , `team` , `home_games_played` , `home_wins` , `home_draws` , `home_losses` ,`home_points, `home_goals_for` , `home_goals_against` , `away_games_played` , `away_wins` , `away_draws` , `away_losses` , `away_points` , `away_goals_for` , `away_goals_against` ) VALUES ( '$username', '$squad', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0')"; return mysql_query($q, $this->connection); } Can you see any obvious reason why this isn't happening?

  • REST services - exposing non-data "actions"

    - by ctacke
    I understand how to use REST for doing general entity interactions - using urls names to map to entities and the HTTP verbs to map to actions on those entities. But what is the generally accepted way of looking at "actions" more like RPC? For example, let's say I want to send a command for the device to reset? There's no real "entity" here or do I do something like POST to http://mydevice/device/reset?

  • How to POST data to an HTTP page from an HTTPS page

    - by buster55
    I know this is a long shot, but I figured I'd ask the question anyway. I have an HTTPS page and am dynamically creating a form. I want to POST the form to an HTTP page. Is this possible without the browser popping up a warning? When I do this on IE8, I get the following message: Do you want to view only the webpage content that was delivered securely? Essentially, I'm asking about the inverse of question 1554237.

  • SQL SELECT INSERTed data from Table

    - by Noam Smadja
    its in ASP Classic. MS-Access DB. i do: INSERT INTO Orders (userId) VALUES (123)" what i want to retrieve is orderNumber from that row. its an auto-increment number. so i did: SELECT orderNumber FROM Orders WHERE userId=123 but since it is on the same page, the SELECT returns: Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record. i've seen somewhere RETURNING orderNumber as variable but it was for oracle and i dont know how to implement it into my asp :( set addOrder = Server.CreateObject("ADODB.Command") addOrder.ActiveConnection = MM_KerenDB_STRING addOrder.CommandText = "INSERT INTO Orders (userId) VALUES ("&userId&")" addOrder.CommandType = 1 addOrder.CommandTimeout = 0 addOrder.Prepared = true addOrder.Execute() Dim getOrderNumber Set getOrderNumber = Server.CreateObject("ADODB.Recordset") getOrderNumber.ActiveConnection = MM_KerenDB_STRING getOrderNumber.Source = "SELECT orderNumber FROM Orders WHERE userId=" & userId getOrderNumber.CursorType = 0 getOrderNumber.CursorLocation = 2 getOrderNumber.LockType = 1 getOrderNumber.Open() session("orderNumber") = getOrderNumber.Fields.Item("orderNumber").value

  • Paging To The End Of A Data View Web Part

    - by ForNow
    Hi all! Hopefully you can help me with this. I've displayed an Announcement web part on a page with 20 items. I opened up SharePoint Designer 2007 and set the paging to 6 items. I've added a little bit of (OOB) functionality so that I have buttons for START, PREVIOUS, and NEXT. These work well without any problems but I'm wondering how do I get END to work? I tried using the $LastRow & $RealLastRow values supplied by the web part but those just give me the number of how many items are in the current view, not the total items in the list. Little help!
