  • PHP MYSQL loop to check if LicenseID Values are contained in mysql DB [closed]

    - by Jasper
    I have some troubles to find the right loop to check if some values are contained in mysql DB. I'm making a software and I want to add license ID. Each user has x keys to use. Now when the user start the client, it invokes a PHP page that check if the Key sent in the POST method is stored in DB or not. If that key isn't store than I need to check the number of his keys. If it's than X I'll ban him otherwise i add the new keys in the DB. I'm new with PHP and MYSQL. I wrote this code and I would know if I can improve it. <?php $user = POST METHOD $licenseID = POST METHOD $resultLic= mysql_query("SELECT id , idUser , idLicense FROM license WHERE idUser = '$user'") or die(mysql_error()); $resultNumber = mysql_num_rows($resultLic); $keyFound = '0'; // If keyfound is 1 the key is stored in DB while ($rows = mysql_fetch_array($resultLic,MYSQL_BOTH)) { //this loop check if the $licenseID is stored in DB or not for($i=0; $i< $resultNumber ; i++) { if($rows['idLicense'] === $licenseID) { //Just for the debug echo("License Found"); $keyFound = '1'; break; } //If key isn't in DB and there are less than 3 keys the new key will be store in DB if($keyfound == '0' && $resultNumber < 3) { mysql_query( Update users set ...Store $licenseID in Table) } // Else mean that the user want user another generated key (from the client) in the DB and i will be ban (It's wrote in TOS terms that they cant use the software on more than 3 different station) else { mysql_query( update users set ban ='1'.....etc ); } } ?> I know that this code seems really bad so i would know how i can improve it. Someone Could give me any advice? I choose to have 2 tables: users where all information about the users is, with fields id, username, password and another table license with fields id, idUsername, idLicense (the last one store license that the software generate)

  • share code between check and process methods

    - by undu
    My job is to refactor an old library for GIS vector data processing. The main class encapsulates a collection of building outlines, and offers different methods for checking data consistency. Those checking functions have an optional parameter that allows to perform some process. For instance: std::vector<Point> checkIntersections(int process_mode = 0); This method tests if some building outlines are intersecting, and return the intersection points. But if you pass a non null argument, the method will modify the outlines to remove the intersection. I think it's pretty bad (at call site, a reader not familiar with the code base will assume that a method called checkSomething only performs a check and doesn't modifiy data) and I want to change this. I also want to avoid code duplication as check and process methods are mostly similar. So I was thinking to something like this: // a private worker std::vector<Point> workerIntersections(int process_mode = 0) { // it's the equivalent of the current checkIntersections, it may perform // a process depending on process_mode } // public interfaces for check and process std::vector<Point> checkIntersections() /* const */ { workerIntersections(0); } std::vector<Point> processIntersections(int process_mode /*I have different process modes*/) { workerIntersections(process_mode); } But that forces me to break const correctness as workerIntersections is a non-const method. How can I separate check and process, avoiding code duplication and keeping const-correctness?

  • VSS to TFS Migration - Persist User on check-in actions

    - by Adam Jenkin
    I am using the VSSConveter.exe tool to import from VSS6 (using 2005 ide) to TFS2008. I have run analyze (no errors) and migrate WITH a user mapping file (containg the vss/domain user mappings) I would like to persist in tfs the check-in user of the file, currently the check-in user for all versions of file shows as admin (the account im running the import with), the origional check-in user is appended to the check-in comment. For example:- TestFile.aspx in VSS Check in ver: 1 - User:Adam - Comment:TEST1 Check in ver: 2 - User:James - Comment:TEST2 Check in ver: 3 - User:Joel - Comment:TEST2 After import into TFS Check in ver: 1 - User:mydomain\Admin - Comment:TEST1 (Commited by Adam) Check in ver: 2 - User:mydomain\Admin - Comment:TEST2 (Commited by James) Check in ver: 3 - User:mydomain\Admin - Comment:TEST2 (Commited by Joel) In TFS I want the user to show as the correct domain user as configured in my user mapping file. Is this possible, or is this just how the VSSConverter program works?

  • Why does String.Equals(Object obj) check to see if this == null?

    - by m-y
    // Determines whether two strings match. [ReliabilityContract(Consistency.WillNotCorruptState, Cer.MayFail)] public override bool Equals(Object obj) { //this is necessary to guard against reverse-pinvokes and //other callers who do not use the callvirt instruction if (this == null) throw new NullReferenceException(); String str = obj as String; if (str == null) return false; if (Object.ReferenceEquals(this, obj)) return true; return EqualsHelper(this, str); } The part I don't understand is the fact that it is checking for the current instance, this, against null. The comment is a bit confusing, so I was wondering what does that comment actually mean? Can anyone give an example of how this could break if that check was not there, and does this mean that I should also place that check in my classes?

  • how to check that Google Analytics Tracking Code is firing on an iPad

    - by crmpicco
    I am used to using the Firebug extension "Omnibug" with Firefox to check that Google Analytics Tracking Code is firing on my website. This application works very well and has minimal overhead. I am now testing the website on an iPad and would like to know if there is a way to check that the GATC is firing on the iPad natively? I have spoofed the iPad UA string on Firefox on the desktop and it appears to fire correctly, however i'd like to see it happening on the device itself (if at all possible). I know that Firebug can be installed on an iPhone by means of a bookmarklet, however it is 1) quite buggy and not very user-friendly and 2) it doesn't support Omnibug. How can I check that my GATC is firing on my iPad?

  • Kernel Panic Fatal Machine Check

    - by 0x4a6f4672
    I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-(

  • What are some commonly used source code check-in policies?

    - by rwmnau
    I'm curious what code review policies other development shops apply to their source code when it's checked into the source control repository. I'm setting up a TFS (Team Foundation) server, and I'd like to apply some check-in policies to start to stamp out bad practices. For example, I was thinking of starting with the following couple, so this is the kind of stuff I'm looking for: Prohibit empty "Catch" blocks. This would prevent applications from swallowing any exceptions without at least requiring a comment explaining why it's not necessary to do anything with the exception. Prohibit "Catch ex as Exception" generic exception handling. Instead, require code to catch specific types of exceptions and deal with them appropriately, instead of just building catch-all handling. Require a check-in comment. This one should be self-explanatory, though it seems that TFS (and most other source-control systems) don't require a comment by default. While these are just examples, they're where I'm thinking of starting, and while I'd like some additional examples of what's popular, I'm open to feedback on these. Also, though we're a mostly .NET shop, I imagine the popular policies are universal across languages and IDEs (we have some Java development and a few people who will use the repository develop with Eclipse).

  • How to create a bash script to check the SSH connection?

    - by chutsu
    I am in the process of creating a bash script that would log into the remote machines and create private and public keys. My problem is that the remote machines are not very reliable, and they are not always up. I need a bash script that would check if the SSH connection is up. Before actually creating the keys for future use.

  • How to check SERP position correctly?

    - by Cengiz Frostclaw
    I wonder how do you check your website's SERP position for a certain query. I cannot directly go to Google and search, because it knows i'm looking for my site, and it shows it in the first position, but from another browser, it cannot be even in the first page. So how do you check for "average user" ? I use Tor browser for that, since it gives me a completely different IP, do you think is it safe? I mean, does it give useful information ?

  • T-SQL Tuesday #016:Check Your Service Accounts with PowerShell

    - by AllenMWhite
    T-SQL Tuesday #016:Check Your Service Accounts with PowerShell This T-SQL Tuesday is about Aggregate Functions. It may be a bit of a stretch, but a security best practice to use separate service accounts for all your SQL Server services, so I've written some PowerShell code to check to see if any account is used more than once on a given machine. I take advantage of the SQLWmiManagement DLL to find the SQL Server services, which is a safer bet than filtering on a service name. First I load the SQLWmiManagement...(read more)

  • Added key, but still getting "gpg: Can't check signature: public key not found"

    - by gertvdijk
    Trying to download Django source package using dget and the .dsc file from here. Then dget fails to verify the source, because it is missing a public key. $ dget https://launchpad.net/ubuntu... [...] dscverify: python-django_1.4.1-2.dsc failed signature check: gpg: Signature made Tue 21 Aug 2012 09:12:04 CEST using RSA key ID F2AC729A gpg: Can't check signature: public key not found Validation FAILED!! Fine, I added this key to my keyring, because I think I can trust this one: $ gpg --keyserver keyserver.ubuntu.com --recv-key 0xF2AC729A gpg: requesting key F2AC729A from hkp server keyserver.ubuntu.com gpg: key F2AC729A: "Raphaël Hertzog <[email protected]>" not changed gpg: Total number processed: 1 gpg: unchanged: 1 (well, this output is run afterwards, when it was already in my keyring) And it is really there: $ gpg --fingerprint F2AC729A pub 4096R/F2AC729A 2009-05-07 Key fingerprint = 3E4F B711 7877 F589 DBCF 06D6 E619 045D F2AC 729A uid Raphaël Hertzog <[email protected]> uid Raphaël Hertzog (Debian) <[email protected]> uid Raphaël Hertzog (Freexian SARL) <[email protected]> sub 2048R/71F23DEE 2009-05-07 But still fails for the same reason: gpg: Signature made Tue 21 Aug 2012 09:12:04 CEST using RSA key ID F2AC729A gpg: Can't check signature: public key not found I'm running all these commands as my regular user. I also tried adding this key to APT's keyring and root's keyring. Both to no avail. What am I missing here?

  • Spell check web pages using Firefox plugin

    - by Gopinath
    Having spelling mistakes on a website degrades customer experience by many times. Developers and website content creators spend good amount of time in going through the content manually to make sure that there are no spelling mistakes. At times few mistakes slip in as manual process is error prone. There are few web services and tool available in the market which provide automated spell checking services but they have certain limitations like – high fees to use the service, limitation on the number of pages they scan for errors, privacy issues, etc. What about a free tool that runs locally on your PC and spell checks unlimited web pages? Here comes Spell Checker extension for  Firefox web browser. This free Firefox extension is developed by  Gaurang, a Software Test Engineer based out in India.

  • How to check Early Z efficiency on AMD GPU with Windows 7

    - by Suma
    I have a game using DirectX 9, and a development station using Win 7 x64. I am still able to get access to another station with Vista x64 / dual booted with WinXP x86. I wanted to check early Z efficiency in the game and to my sadness all tools I have tried seem to be unable to perform this task: AMD PerfStudio AMD GPUPerfStudio 2 does not support DirectX 9 at all AMD GPUPerfStudio 1.2 does not install correctly on Windows 7. When I have tweaked the MSI package (a simple OS version check adjustment was needed), it complained the drivers I have do not provide needed instrumentation. The drivers old enough to support the GPUPerfStudio would most likely not be able to operate with my Radeon 5750 card (though this is something I am not 100 % sure, I did not attempt to try any older drivers, not knowing which I should look for) PIX PIX does not seem to contain any counters like this. It offers some ATI specific counters, but when I try to activate them, the PIX reports "PIX encountered a problem while attaching to the target program." I do not want to upgrade to DX 10/11 just to be able to profile the game, but it seems without the step I am somewhat locked with a toolset which is no longer supported. I see only one obvious options which would probably work, and that is using WinXP (or with a little bit of luck even Vista) station, perhaps with some older AMD card, to make sure GPUPerfStudio 1.2 works. Other than that, can anyone recommend other options how to check GPU HW counters (HiZ / EarlyZ in particular, but if others would be enabled as well, it would be a nice bonus) for a DirectX 9 game on Windows 7, preferably on AMD GPU? (If that is not possible, I would definitely prefer switching GPU to switching the OS, but before I do so I would like to know if I will not hit the same problem with nVidia again)

  • Brother MFC-J470DW scan function "Check Connection"

    - by user292599
    I have a Brother MFC-J470DW printer that I have connected to a Linux desktop (running Ubuntu 14.04) using a wireless router network. The printer works fine for printing and copying, but now I want to add the scan function. To set up the scan function, I went to the Brother web page for this printer: http://support.brother.com/g/b/downloadlist.aspx?c=eu_ot&lang=en&prod=mfcj470dw_us_eu_as&os=128 and under Scanner Drivers selected "Scanner driver 64bit (deb package)", "Scan-key-tool 64bit (deb package)", and "Scanner Setting file (deb package)". For each package, I clicked the EULA, and selected "open with Ubuntu Software Center". Then after the USC window pops up, I click on Install and the red line goes from left to right. In each case, the USC window then had a green checkmark and the Install box changes to Reinstall (that's how you know it worked). So now I try it out. Hitting the Scan button on the printer, selecting "Scan to file", and hitting ok produces the message "Check Connection". I checked the Brother Linux Information FAQ (scanner) page and the 14th question seems the same as mine: When I try to use the scan key on my network connected machine, I receive the error "Check connection" or I can not select anything except "scan to FTP". I explored the solution given for this FAQ, but found from ifconfig that I am already using eth0, the default setting, so presumably that is not the problem. I also found brscan-skey installed in /usr/bin and did drrm@drrmlinux2:~$ brscan-skey -t drrm@drrmlinux2:~$ brscan-skey but that didn't help - I still get the "Check connection" message. What can you suggest to fix this problem?

  • Ubuntu 12.04 64 bit doesn't work on a win7 with check point full disk encryption

    - by Victor Rodriguez
    I installed Ubuntu 12.04 64 bit with the Wubi installer on a Windows 7 with Check Point Full Disk Encryption. The Wubi Installer runs without any trouble selecting the compatibility mode with WinXP and as Administrator. The problem is that after the installation is complete and the reboot done, when you restart the system, there's no option to start Ubuntu instead of Windows. I recently installed Ubuntu on other Win7 machines without any problem. But those laptops don't have the Check Point Full Disk Encryption. And when you restart the system you have the option to start in Ubuntu. If somebody has resolved this issue please share...!!! Regards! Víctor

  • Tor check failed though Vidalia shows green onion

    - by Wolter Hellmund
    I have installed tor successfully and Vidalia shows it is running without problems; however, when I check if I am using tor in this website I get an error message saying I am not using tor. I have tried two things to fix this: I installed ProxySwitchy on Google Chrome, and created a profile for Tor (with address 127.0.0.1, port 8118), but enabling the proxy doesn't change the results in the tor check website linked before. I changed my network proxy settings through System Settings Network from None to Manual, and selected as address always 127.0.0.1 and as port 8118 for all but for the socket, for which I entered 9050 instead. This makes internet stop working completely. How can I fix this problem?

  • SQL SERVER – Check If Column Exists in SQL Server Table

    - by Pinal Dave
    A very frequent task among SQL developers is to check if any specific column exists in the database table or not. Based on the output developers perform various tasks. Here are couple of simple tricks which you can use to check if column exists in your database table or not. Method 1 IF EXISTS(SELECT * FROM sys.columns WHERE Name = N'columnName' AND OBJECT_ID = OBJECT_ID(N'tableName')) BEGIN PRINT 'Your Column Exists' END   For AdventureWorks sample database IF EXISTS(SELECT * FROM sys.columns WHERE Name = N'Name' AND OBJECT_ID = OBJECT_ID(N'[HumanResources].[Department]')) BEGIN PRINT 'Your Column Exists' END   Method 2 IF COL_LENGTH('table_name','column_name') IS NOT NULL BEGIN PRINT 'Your Column Exists' END For AdventureWorks sample database IF COL_LENGTH('[HumanResources].[Department]','Name') IS NOT NULL BEGIN PRINT 'Your Column Exists' END Method 3 IF EXISTS( SELECT TOP 1 * FROM INFORMATION_SCHEMA.COLUMNS WHERE [TABLE_NAME] = 'TableName' AND [COLUMN_NAME] = 'ColumnName' AND [TABLE_SCHEMA] = 'SchemaName') BEGIN PRINT 'Your Column Exists' END For AdventureWorks sample database IF EXISTS( SELECT TOP 1 * FROM INFORMATION_SCHEMA.COLUMNS WHERE [TABLE_NAME] = 'Department' AND [COLUMN_NAME] = 'Name' AND [TABLE_SCHEMA] = 'HumanResources') BEGIN PRINT 'Your Column Exists' END Let me know if you know any other method to find if Column Exists in SQL Server Table.
