  • Arguments, local variables, and global variables coding convention in Python

    - by prosseek
    In python, there is no way to differentiate between arguments, local variables, and global variables. The easy way to do so might be have some coding convention such as Global variables start with _ and capital letter arguments end with with _ _Gvariable = 10 def hello(x_, y_): z = x_ + y_ Is this a Pythonian way to go? I mean, is there well established/agreed coding-standards to differentiate them in python?

  • SQL Server 2000 tables

    - by klork
    We currently have an SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: Does anyone have any experience with a SQL Server (2000/2005) installation with millions of tables? What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

  • Query through linked server is very slow

    - by Sergey Olontsev
    I have 2 SQL 2005 servers SRV1 and SRV2. SRV2 is the linked server on SRV1. I run a storep proc with params on SRV2 and it is completed immediately. But when I run the same proc through the linked server on SRV1, for example EXEC [SRV1].DB_TEST.dbo.p_sample_proc it takes about 8-10 minutes to complete. After restarting SRV2 the problem is gone. But some time later it returns. Does anyone have any ideas what it could be?

  • How to set user environment variables in Windows Server 2008 R2 as a normal user?

    - by likm
    In older versions of Windows, it was just open the Control Panel, select the System applet, select the Advanced tab, and then hit the Environment variables button. As a normal user, you could edit the "User variables" but not the "System variables". In Windows Server 2008 R2, if I try to hit the Advanced System settings option in the System applet, it prompts for the Administrator password.

  • Flash As3.0 PHP Variables?

    - by user311421
    Is it possible to make php variables public and accessible anywhere on the timeline? The script I included works fine if I set it as the document class only (it won't work if I try importing it). The variables pass the text to dynamic text fields on the main timeline. The problem: It will pull the information and display it when the SWF first loads but if I move to my second frame and then back it erases the information. It also will not pass any variables to the second frame. The only way to see the variables after going back to the first frame is to reload the whole SWF. I'm pretty much stuck at this point trying to make the variables persistent through all frames. this is my code: package { import flash.display.MovieClip; import flash.events.*; import flash.net.*; import flash.display.Stage; public class Main extends MovieClip { public function Main() { var request:URLRequest = new URLRequest("http://localhost/mytest2/dataLayer.php"); request.method = URLRequestMethod.GET; var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.VARIABLES; loader.addEventListener(Event.COMPLETE, completeHandler); loader.load(request); function completeHandler(evt:Event) { var username = evt.target.data.username; var pclass = evt.target.data.pclass; var hpoints = evt.target.data.hpoints; var spoints = evt.target.data.spoints; username_txt.text = username; class_txt.text = pclass; hpoints_txt.text = hpoints; spoints_txt.text = spoints; } } } }

  • Windows Server 2003 R2 SP2 can't access the internet

    - by Ishmael
    Our 64-bit windows server can no longer access the internet although it is a web-server that is hosting webpages accessible by the internet. Since this dilemma the server can no longer receive windows updates or Symantec virus definitions. We have checked our firewalls so nothing is blocked. Any insight on why this issue happened would be appreciated. Also the server is running IE6 which we have been trying to update.

    Hi. I am setting up a BizTalk 2009 Server production environment and I wonder if this tutorial: http://msdn.microsoft.com/en-us/library/cc558972(BTS.10).aspx is still fairly accurate for an installation on all the latest platform software (Hyper-V, Windows Server 2008, BizTalk Server 2009, SQL Server 2008)? Is there anything like this but more up to date? Any other advice about this process and links to articles, blogs & tutorials would be appreciated.

  • VPN server on Windows Server 2008 for a small office

    - by cmbrnt
    I'm going to refurbish the IT-infrastructure for a small organization with one single office, and I'm not sure what VPN server to use. In your opinion, would the built-in Windows Server 2008 VPN server suffice or are there any specific problems with it as opposed to, for example, OpenVPN? I'd rather run a Windows native VPN server, but if there are few (preferably free) good alternatives, I could install VMware ESXi and virtualize both Windows and an OpenVPN-server. By the way, because of a low budget this office runs a solution with only one physical server. Any advice would be great to help me grasp this field of which I'm quite a novice. Thank you!

  • C# How to communicate between 2 servers

    - by Chau
    I have a website running ASP.NET (C#) on server A. I need my website to access a webservice on server B. server B will only accept incoming requests if the requestee is located within a certain IP range and server A is not within this range. I have a server server C which is located within the IP range and the only thing blocking server A from server C is a firewall (which I have access to). It must be possible to create a hole in the firewall between server A and server C, but my question is: How do I relay the request from server A to server B via server C? I need the response from server B to get back to server A also :) Thanks in advance.

  • Users suddenly missing write permissions to the root drive c within an active directory domain

    - by Kevin
    I'm managing an active directory single domain environment on some Windows Server 2008, Windows Server 2008 R2 and Windows Server 2012 machines. Since a few weeks I got a strange issue. Some users (not all!) report that they cannot any longer save, copy or write files to the root drive c, whether on their clients (vista, win 7) nor via remote desktop connection on a Windows Server 2008 machine. Even running programs that require direct write permissions to the root drive without administrator permissions fail to do so since then. The affected users have local administrator permissions. The question I'm facing now is: What caused this change of system behavior? Why did this happen? I didn't find out yet. What was the last thing I did before it happened? The last action that was made before it happened was the rollout of a GPO containing network drive mappings for the users depending on their security group membership. All network drives are located on a linux server with samba enabled. We did not change any UAC settings, and they have always been activated. However I can't imagine that rolling out this GPO caused the problem. Has anybody faced an issue like that? Just in case: I know that it is for a specific reason that an user without administrative privileges is prevented from writing to the root drive since windows vista and the implementation of UAC. I don't think that those users should be able to write to drive c, but I try to figure out why this is happening and a few weeks ago this was still working. I also know that a user who is a member of the local administrators group does not execute anything with administrator permissions per default unless he or she executes a program with this permissions. What did I do yet? I checked the permissions of the affected programs, the affected clients/server. Didn't find something special. I checked ALL of our GPOs if there exist any restrictions that could prevent the affected users from writing to the root drive. Did not find any settings. I checked the UAC settings of the affected users and compared those to other users that still can write to the root drive. Everything similar. I googled though the internet and tried to find someone who had a similar problem. Did not find one. Has anybody an idea? Thank you very much. Edit: The GPO that was rolled out does the following (Please excuse if the settings are not named exactly like that, I translated the settings into english): **Windows Settings -- Network Drive Mappings -- Drive N: -- General:** Action: Replace **Properties:** Letter: N Location: \\path-to-drive\drivename Re-Establish connection: deactivated Label as: Name_of_the_Share Use first available Option: deactivated **Windows Settings -- Network Drive Mappings -- Drive N: -- Public: Options:** On error don't process any further elements for this extension: no Run as the logged in user: no remove element if it is not applied anymore: no Only apply once: no **Securitygroup:** Attribute -- Value bool -- AND not -- 0 name -- domain\groupname sid -- sid-of-the-group userContext -- 1 primaryGroup -- 0 localGroup -- 0 **Securitygroup:** Attribute -- Value bool -- OR not -- 0 name -- domain\another-groupname sid -- sid-of-the-group userContext -- 1 primaryGroup -- 0 localGroup -- 0 Edit: The Error-Message of an affected users says the following: Due to an unexpected error you can't copy the file. Error-Code 0x80070522: The client is missing a required permission. The command icacls C: shows the following: NT-AUTORITY\SYSTEM:(OI)(CI)(F) PRE-DEFINED\Administrators:(OI)(CI)(F) computername\username:(OI)(CI)(F) A college just told me that also the primary domain-controller (PDC) changed from Windows Server 2008 to Windows Server 2012. That also may be a reason. Any suggestions?

  • View all ntext column text in SQL Server Management Studio for SQL CE database

    - by Dave
    I often want to do a "quick check" of the value of a large text column in SQL Server Management Studio (SSMS). The maximum number of characters that SSMS will let you view, in grid results mode, is 65535. (It is even less in text results mode.) Sometimes I need to see something beyond that range. Using SQL Server 2005 databases, I often used the trick of converting it to XML, because SSMS lets you view much larger amounts of text that way: SELECT CONVERT(xml, MyCol) FROM MyTable WHERE ... But now I am using SQL CE, and there is no Xml data type. There is still a "Maximum Characters Retreived XML" value under Options; I suppose this is useful when connecting to other data sources. I know I can just get the full value by running a little console app or something, but is there a way within SSMS to see the entire ntext column value? [Edit] OK, this didn't get much attention the first time around (18 views?!). It's not a huge concern, but maybe I'm just obsessed with it. There has to be some good way around this, doesn't there? So a modest bounty is active. What I am willing to accept as answers, in order from best-to-worst: A solution that works just as easy as the XML trick in SQL CE. That is, a single function (convert, cast, etc.) that does the job. A not-too-invasive way to hack SSMS to get it to display more text in the results. An equivalent SQL query (perhaps something that creatively uses SUBSTRING and generates multiple ad-hoc columns??) to see the results. The solution should work with nvarchar and ntext columns of any length in SQL CE from SSMS. Any ideas?

  • What is the suggested approach to Syncing/Backing up/Restoring from SQL Server 2008 to SQL Server 20

    - by Eoin Campbell
    I only have SQL Server 2008 (Dev Edition) on my development machine I only have SQL Server 2005 available with my hosting company (and I don't have direct connection access to this database) I'm just wondering what the best approach is for: Getting the initlal DB Structure & Data into production. And keeping any structural changes/data changes in sync in future. As far as I can see... Replication - not an option cos I can't connect to the production DB. Restoring a backup - not an option because as far as I can see, you cannot export a DB from 2008 that is restorable in 2005 (even with the 2008 DB set in 2005 compatibility mode) and it wouldn't make sense to be restoring production over the top of my dev version anyway. Dump all the scripts from my 2008 Database, Revert my Dev to machine from 2008 - 2005, and recreate the database from the scripts, then just use backup & restore to get the initial DB into production, then run scripts through the web panel from that point onwards Dump all the scripts from my 2008 Database and generate the entire 2005 db from scripts in production. then run scripts through the web panel from that point onwards With the last 2 options, I'd probably need to script all the data inserts as well using some tool (which I presume exists on the web) Are there any other possibile solutions that I'm not considering.

  • SQL SERVER – Table Variables and Transactions – SQL in Sixty Seconds #007 – Video

    - by pinaldave
    Today’s SQL in Sixty Seconds video is inspired from my presentation at TechEd India 2012 on Misconception and Resolution. Quite often I have seen people getting confused with certain behavior of the T-SQL. They expect SQL to behave certain way and SQL Server behave differently. This kind of issue often creates confusion and frustration. Sometime I have seen them also confusing it with bug and submitting the bug, where reality is totally different. Similar concept which are going to see today. I have seen quite commonly developer assuming that table various will be rolled back when transaction is rolled back. This sixty seconds video describes that table various are not rolled back when transactions are rolled back. More on Errors: Difference Temp Table and Table Variable – Effect of Transaction Effect of TRANSACTION on Local Variable – After ROLLBACK and After COMMIT Debate – Table Variables vs Temporary Tables – Quiz – Puzzle – 13 of 31 I encourage you to submit your ideas for SQL in Sixty Seconds. We will try to accommodate as many as we can.

  • Please Describe Your Struggles with Minimizing Use of Global Variables

    - by MetaHyperBolic
    Most of the programs I write are relatively flowchartable processes, with a defined start and hoped-for end. The problems themselves can be complex but do not readily lean towards central use of objects and event-driven programming. Often, I am simply churning through great varied batches of text data to produce different text data. Only occasionally do I need to create a class: As an example, to track warnings, errors, and debugging message, I created a class (Problems) with one instantiation (myErr), which I believe to be an example of the Singleton design pattern. As a further factor, my colleagues are more old school (procedural) than I and are unacquainted with object-oriented programming, so I am loath to create things they could not puzzle through. And yet I hear, again and again, how even the Singleton design pattern is really an anti-pattern and ought to be avoided because Global Variables Are Bad. Minor functions need few arguments passed to them and have no need to know of configuration (unchanging) or program state (changing) -- I agree. However, the functions in the middle of the chain, which primarily control program flow, have a need for a large number of configuration variables and some program state variables. I believe passing a dozen or more arguments along to a function is a "solution," but hardly an attractive one. I could, of course, cram variables into a single hash/dict/associative array, but that seems like cheating. For instance, connecting to the Active Directory to make a new account, I need such configuration variables as an administrative username, password, a target OU, some default groups, a domain, etc. I would have to pass those arguments down through a variety of functions which would not even use them, merely shuffle them off down through a chain which would eventually lead to the function that actually needs them. I would at least declare the configuration variables to be constant, to protect them, but my language of choice these days (Python) provides no simple manner to do this, though recipes do exist as workarounds. Numerous Stack Overflow questions have hit on the why? of the badness and the requisite shunning, but do not often mention tips on living with this quasi-religious restriction. How have you resolved, or at least made peace with, the issue of global variables and program state? Where have you made compromises? What have your tricks been, aside from shoving around flocks of arguments to functions?
