  • Array as struct database?

    - by user2985179
    I have a struct that reads data from the user: typedef struct { int seconds; } Time; typedef struct { Time time; double distance; } Training; Training input; scanf("%d %lf", input.time.seconds, input.distance); This scanf will be looped and the user can input different data every time, I want to store this data in an array for later use. I THINK I want something like arr[0].seconds and arr[0].distance. I tried to store the entered data in an array but it didn't really work at all... Training data[10]; data[10].seconds = input.time.seconds; data[10].distance = input.distance; The data will wipe when the program closes and that's how I like it to be. So I want it to be stored in an array, no files or databases!

  • Access violation C++ (Deleting items in a vector)

    - by Gio Borje
    I'm trying to remove non-matching results from a memory scanner I'm writing in C++ as practice. When the memory is initially scanned, all results are stored into the _results vector. Later, the _results are scanned again and should erase items that no longer match. The error: Unhandled exception at 0x004016f4 in .exe: 0xC0000005: Access violation reading location 0x0090c000. // Receives data DWORD buffer; for (vector<memblock>::iterator it = MemoryScanner::_results.begin(); it != MemoryScanner::_results.end(); ++it) { // Reads data from an area of memory into buffer ReadProcessMemory(MemoryScanner::_hProc, (LPVOID)(*it).address, &buffer, sizeof(buffer), NULL); if (value != buffer) { MemoryScanner::_results.erase(it); // where the program breaks } }

  • maintain formatting entered into an html form?

    - by NickG77
    Im setting up a web form, and I'm trying to have it where visitors can paste their resumes into a text area. Then I want to email the info using php mail(). But the resume info is just stored in the variable as one long string with no formatting. Is there a way I can send the pasted resume text to the client in the resume format? Maintaining all the line breaks and stuff? He wants to avoid having people upload resumes.

  • Rspec > testing database views

    - by Sean McCleary
    How can database views be tested in Rspec? Every scenario is wrapped in a transaction and the data does not look like it is being persisted to the database (MySQL in my case). My view returns with an empty result set because none of the records are being persisted in the transaction. I am validating that the records are not being stored by setting a debug point in my spec and checking my data with a database client while the spec is being debugged. The only way I can think to have my view work would be if I could commit the transaction before the end of the scenario and then clear the database after the scenario is complete. Does anyone know how to accomplish this or is there a better way? Thanks

    - by zengr
    public class hello { public static void main(String[] args) { Object[] newarray = new Object[1]; Object[] obj = new Object[2]; obj[0] = "Number1"; //string value obj[1] = "Number2"; //string value newarray[0] = obj; //this works Object[] tmp_obj = new Object[2]; tmp_obj = newarray[0]; //obviously does not work System.out.println(tmp_obj[0]); //nope System.out.println(tmp_obj[1]); //nope } } So, now if I want to access the values "Number1" and "Number2" which are stored in obj[0] and obj[1]; obj is in newarray[0]. what should I do? Is this a possible? Thanks

  • cakephp droplist/form - xml and ajax

    - by gudinne
    Hello- I'm complete noob in Cakephp - here goes... I have a website set up with Cakephp framework. I have been tasked with creating two dropdown forms to compare/show data. When the user selects an item from the dropdown from either one of the forms it is to show the content below on website. I was thinking this data would need to be stored in an xml file. How do I create and sync two dropdown forms with xml data within Cakephp? The page the form is on is the view(.ctp) file. Thanks

  • C#: Select row from DataGridView

    - by Bi
    Hi I have a form with a DataGridView (of 3 columns) and a Button. Every time the user clicks on a button, I want the get the values stored in the 1st column of that row. Here is the code I have: private void myButton_Click(object sender, EventArgs e) { foreach (DataGridViewRow row in ProductsGrid.Rows) { if (this.ProductsGrid.SelectedRows.Count == 1) { // get information of 1st column from the row string value = this.ProductsGrid.SelectedRows[0].Cells[0].ToString(); } } } However when I click on myButton, the this.ProductsGrid.SelectedRows.Count is 0. Also, how do I ensure that the user selects only one row and not multiple rows? Does this code look right?

  • Lua : How to check if one of the values associated with the specified key of a table is nil, from ap

    - by felace
    In lua, it's legal to do this : table={} bar if(table[key]==nil) foo However, using C API, I couldn't find way to check if there's a nil value on the specified position. lua_getglobal(L,"table"); lua_gettable(L,key); If there's a nil value stored in table[key], lua_gettable would give me the "unprotected error in call to Lua API (attempt to index a nil value)" message. Is there any way to check if there's actually something associated with that key, before actually pushing the key to do so ?

  • 32/64 Bit Question

    - by user48408
    Here's my question. What is the best way to determine what bit architecture your app is running on? What I am looking to do: On a 64 bit server I want my app to read 64 bit datasources (stored in reg key Software\Wow6432Node\ODBC\ODBC.INI\ODBC Data Sources) and if its 32 bit I want to read 32 bit datasources, (i.e. Read from Software\ODBC\ODBC.INI\ODBC Data Sources). I might be missing the point, but I don't want to care what mode my app is running in. I simply want to know if the OS is 32 or 64 bit. [System.Environment.OSVersion.Platform doesn't seem to be cutting it for me. Its returning Win32NT on my local xp machine and on a win2k8 64 bit server (even when all my projects are set to target 'any cpu')]

  • Can't get a List(Of <my class>) from a Dictionary in .NET?

    - by magsto
    I have a Dictionary with key of type UInteger and the value is List(Of Session) where the (Public) class Session contains a couple of variables and a constructor (Public Sub New(...)). Some of the variables in my Session class is: Private count As Integer Private StartDate As Date Private Values As List(Of Integer) and a couple of methods like: Friend Sub Counter(ByVal c as Integer) count += c End Sub There is no problem to add values to the Dictionary: Dim Sessions As New List(Of Session) Dim dict As New Dictionary(Of Integer, Sessions) then some code to fill up a couple of Session objects in Sessions (not shown here) and then: dict.Add(17, Sessions) 'No problem Sessions.Clear() Sessions = dict(17) 'This doesn't return anything! The Sessions object is empty even if the code doesn't returned any error. Is my class Session to compex to be stored in a Dictionary?

  • MySQL returns fewer rows with GROUP BY statement

    - by bschaeffer
    I've got a MySQL database that stores image information. Right now it only has three rows stored in the database, and each row is associated with something like, for instance, a unique blog post via a key column. As of right now, one "blog post key" has one image, and one has two images in the database. When I run this query, MySQL returns all three rows. SELECT `id`, `key`, `url` FROM (`images`) WHERE `key` = 'TpaS4G5h' OR `key` = '78855e44' However, when i add the GROUP BY statement I only get two rows... one for each key. SELECT `id`, `key`, `url` FROM (`images`) WHERE `key` = 'TpaS4G5h' OR `key` = '78855e44' GROUP BY `key` I'm sure there is a simple solution, but I don't know what it is... so any help would be really appreciated. Thanks in advance!

  • Structure question over Local/Remote Services, Broadcast Receivers, and Intent Services

    - by Ryan
    I'm writing an android app that has a standard activity, but also needs to monitor incoming/outgoing calls and texts at all times. In addition, the app needs to notify users of information once a day without having the activity open. The information it notifies users of is stored in a database, so communication with the activity is not necessary. I've been researching for a week and still can't decide how to go about doing this. My instinct tells me I need a remote service that has a constantly running broadcast receiver, but every remote service example I see is overly complicated. Could anyone help me better understand what steps I need to take? Thanks in advance.

  • ASP: using existing Crystal Report with date parameter

    - by eric3141
    I have an existing Crystal Report done in Crystal Reports version 9. I need to display it via an ASP website created in Visual Studio 2008. I have put the Crystal data source and viewer controls on the design page and configured the controls to use the crystal report but cannot seem to figure out how to pass a date to the report which uses it as an input parameter for a SQL Server 2005 stored procedure. I have tried putting a calendar control on the design page but don't know how to use it to pass the date parameter. Thanks in advance for any help. Eric

  • MySQL features I can rely on being available

    - by xrstf
    So I'm developing a PHP/MySQL based CMS which requires PHP 5.1 and MySQL 5.0 (with InnoDB support) at least. I'm now wondering what features of MySQL I can safely use without noticing one day that "Oh, well, that crappy hoster has disabled feature X, damn, now I'm screwed." So my question is, which of these features can become problematic (= can be disabled, require special configuration, require user privilege): transactions and FKs in InnoDB (of course unavailable to MyISAM) table locking (MyISAM and InnoDB) stored procedures I just want to know once and for all what's the minimal feature set I can expect from MySQL.

  • Why can't i call Contains method from my array?

    - by xbnevan
    Arrrg!I am running into what i feel is a dumb issue with a simple script i'm writing in powershell. I am invoking a sql command that is calling a stored proc, with the results i put it a array. The results look something like this: Status ProcessStartTime ProcessEndTime ------ ---------------- -------------- Expired May 22 2010 8:31PM May 22 2010 8:32PM What i'm trying to do is if($s.Contains("Expired")) , report failed. Simple...? :( Problem i'm running into is it looks like Contains method is not being loaded as i get an error like this: Method invocation failed because [System.Object[]] doesn't contain a method named 'Contains'. At line:1 char:12 + $s.Contains <<<< ("Expired") + CategoryInfo : InvalidOperation: (Contains:String) [], RuntimeException + FullyQualifiedErrorId : MethodNotFound So, what can i do to stop powershell from unrolling it to string? Actual ps script below - $s = @(Invoke-Sqlcmd -Query "USE DB GO exec Monitor_TEST_ps 'EXPORT_RUN',NULL,20 " ` -ServerInstance "testdb002\testdb_002") if ($s.Contains("Expired")) { Write-Host "Expired found, FAIL." } else { Write-Host "Not found, OK." }

  • For securing forms, when do I issue the token?

    - by AQuestionADayKeepsTheDrAway
    So, I have a form, to make it a little more secure and potentially help prevent CSRF attacks I want to add a random token value in a hidden field that value is also stored server side in my session data. When should I issue a new token? Per form? Per page load where there is any form? Per session? I can render it invalid as soon as a form is successfully submitted but I'm wondering when to generate one. I ask as if I issue it per form or per page do I not risk the chance of a duplicate token value overwriting the existing (valid) token if a user opens a separate window but submitting the first form (with the now overwritten value)?

  • How to update JLabel in Swing?

    - by Roman
    I am trying to use Swing Timer and I wanted to start from a very simple program. I have a window with text: "You have n seconds", where n changes from 10 to 0 every second. I know how to generate a window with text. And I understand how Timer works (it starts an action periodically). But I cannot figure out how to combing this two things. Should I use that: JLabel label = new JLabel(myMessage); and then with timer I need to update the "myMessage" variable? But I think I need to "force" my window to "update" itself (to display a new value stored in "myMessage").

  • MySQL null/empty-string too long for VarChar(5) ?

    - by rlb.usa
    I have a stored procedure that takes an input var_zip varchar(5). My webapp calls this procedure and gives it the parameter: cmd.Parameters.Add(new MySqlParameter("var_Zip", MySqlDbType.VarChar, 5)); cmd.Parameters["var_Zip"].Value = txtZip.Text; txtZip is empty. So it is either giving empty string '', or null. Doesn't matter to me which. But it is throwing an error: MySql.Data.MySqlClient.MySqlException: Data too long for column 'var_Zip' at row 1 What's going on and how can I fix it? I don't understand.

  • Sql Server query performance

    - by Macros
    I have a stored procedure on a busy database which constantly come out top in the list of expensive queries (by some way). The query is very simple, it takes a single parameter (@ID, int) which is the primary key of the table, and selects the record that matches that ID. The primary key is an identity field with a clustered index, so I am stumped as to how to optimise this any further? The query is as follows CREATE PROCEDURE [dbo].[P_Call_Get] @ID int = null AS select ID, AppID, AgentID, AgentLogin, Ext, VDN, VDNName, Skill, SkillName, CallFrom, TelNoFrom, ParentCallID, CallStart, ACWStart, CallEnd, Outcome, StageID, TxTo, TxSuccess, ServiceID, DiallerID, CRC, TSCallID, CallDirection, [Manual], CallBackAgent, CallBackDateTime, Notes from P_Call where (ID = @ID or @ID is null) Not sure the best way to post the execution plan - all it shows is that 100% of the operation is taken up by the clustered index scan

  • how to store a date, and then check to see if another date matches that date

    - by user797963
    I'm trying to figure out dates in Java and am completely lost. Do I use Date? Use epoch time? Gregorian Calendar? Let's say I have a want to store a date, then later compare it to other dates. For example, I've stored a date "10/27/2013". Then, I want to later compare it to dates entered later to see if a later date is identical to "10/27/2013", or if just the day, year, or month matches? What's the best way to do this?

  • building treeview

    - by DJPlayer
    I'm dynamically building a treeview given numerous stored procedures. the structure goes like this: OwnerRPColl.Search2() For Each root As OWNER_RP In OwnerRPColl Dim nd_Root As New TreeNode nd_Root = TreeView1.Nodes.Add(root.OWNER_RP_BUSNS_NAME) bldg.ID = root.ID bldgColl.Search(bldg.ID) For Each firstChild As BLDG In bldgColl Dim nd_lvl_One As New TreeNode With nd_lvl_One .Text = firstChild.BLDG_NAME_1 .Tag = firstChild.ID End With problem being is that I need to have labels for these.. meaning the first level of the treeview needs to say "users" when expanded displays users. Each of these users can have a building. The world building needs to be the example option, which then displays the building.. essentially I need a slick way to add the word in for the expanding level (instead of the value in the collection).

  • Advice regarding Java frameworks [closed]

    - by Mixiul
    I am in the process of creating a website/phone application using JQuery Mobile and PhoneGap. I am hoping to add openID support so users can login in with pre-existing accounts. It will be necessary for me to have a database with a few tables to enable me to implement all the core functionality I desire. I haven't really had much experience with frameworks before, the closest thing I have done to this is create a basic website using php that connected to a MySql database stored on the machine that hosted the apache webserver. The interaction with the database won't be complex. I am required to use a java framework for the backend of my application. My question is which java framework is most suitable (flexible and straight forward to learn)? Any advice you guys can provide is greatly appreciated. Thanks

  • Version Control in Visual Studio

    - by keynesiancross
    Hi all, I'm currently working on a large project, and am about to make some large changes, and was looking for a way to 'backup' my prior work. Is there built in functionality in Visual Studio to work with version control? This project is developed only by me, and doesn't use Team Foundation Server (which is what most of my googling seems to give me answers on). Ideally, I would like to identify and restore all the different versions of my program as it evolves, without having to worry about totally messing something up... Cheers and thanks in advance! ---EDIT--- With a version control system though, would that be stored on a seperate server? Or is it possible to store it locally? I'm more just concerned that I will just seriously mess up my code and not be able to undo it at some point...
