• Excel VBA to Update SQL Table

  - by user307655

  Hi All, I have a small excel program that is use to upload data to an SQL server. This has been working well for a while. My problem now is that I would like to offer to users a function to update an existing record in SQL. As each row on this table has a unique id columne. There is a column call UID which is the primary key. This is part of the code currently to upload new data: Set Cn = New ADODB.Connection Cn.Open "Driver={SQL Server};Server=" & ServerName & ";Database=" & DatabaseName & _ ";Uid=" & UserID & ";Pwd=" & Password & ";" rs.Open TableName, Cn, adOpenKeyset, adLockOptimistic For RowCounter = StartRow To EndRow rs.AddNew For ColCounter = 1 To NoOfFields rs(ColCounter - 1) = shtSheetToWork.Cells(RowCounter, ColCounter) Next ColCounter Next RowCounter rs.UpdateBatch ' Tidy up rs.Close Set rs = Nothing Cn.Close Set Cn = Nothing Is there anyway i can modify this code to update a particular UID rather than importing new records? Thanks again for your help

• auto Focus (Hit Enter) Javascript function is working good in IE7 but not working in IE8

  - by James123

  Hi, I used a javascript FocusChange() in my aspx page. I have couple of controls and I need Hit enter key need to move next control based on tab index. It is working good in IE7 but not working in IE8... Please help me on this.. Thanks for your help in advance. The java script is given below. function FocusChange() { if (window.event.keyCode == 13) { var formLength = document.form1.length; // Get number of elements in the form var src = window.event.srcElement; // Gets the field having focus var currentTabIndex = src.getAttribute('tabindex'); // Gets its tabindex // scroll through all form elements and set focus in field having next tabindex for (var i = 0; i < formLength; i++) { if (document.form1.elements[i].getAttribute('tabindex') == currentTabIndex + 1) { for (var j = i; j <= formLength; j++) { if (document.form1.elements[j].disabled == false) { document.form1.elements[j].focus(); event.returnValue = false; event.cancel = true; return; } } } } } }

• Bit reversal of an integer, ignoring integer size and endianness

  - by ??O?????

  Given an integer typedef: typedef unsigned int TYPE; or typedef unsigned long TYPE; I have the following code to reverse the bits of an integer: TYPE max_bit= (TYPE)-1; void reverse_int_setup() { TYPE bits= (TYPE)max_bit; while (bits <<= 1) max_bit= bits; } TYPE reverse_int(TYPE arg) { TYPE bit_setter= 1, bit_tester= max_bit, result= 0; for (result= 0; bit_tester; bit_tester>>= 1, bit_setter<<= 1) if (arg & bit_tester) result|= bit_setter; return result; } One just needs first to run reverse_int_setup(), which stores an integer with the highest bit turned on, then any call to reverse_int(arg) returns arg with its bits reversed (to be used as a key to a binary tree, taken from an increasing counter, but that's more or less irrelevant). Is there a platform-agnostic way to have in compile-time the correct value for max_int after the call to reverse_int_setup(); Otherwise, is there an algorithm you consider better/leaner than the one I have for reverse_int()? Thanks.

• Entity Framework query not returning correctly enumerated results.

  - by SkippyFire

  I have this really strange problem where my entity framework query isn't enumerating correctly. The SQL Server table I'm using has a table with a Sku field, and the column is "distinct". It isn't a key, but it doesn't contain any duplicate values. Using actual SQL with where, distinct and group by cluases I have confirmed this. However, when I do this: // Not good foreach(var product in dc.Products) or // Not good foreach(var product in dc.Products.ToList()) or // Not good foreach(var product in dc.Products.OrderBy(p => p.Sku)) the first two objects that are returned ARE THE SAME!!! The third item was technically the second item in the table, but then the fourth item was the first row from the table again!!! The only solution I have found is to use the Distinct extension method, which shouldn't really do anything in this situation: // Good foreach(var product in dc.Products.ToList().Distinct()) Another weird thing about this is that the count of the resulting queries is the same!!! So whether or not the resulting enumerable has the correct results or duplicates, I always get the number of rows in the actual table! (No I don't have a limit clause anywhere). What could possibly cause this!?!?!?

• Error Cannot create an Instance of "ObjectName" in Designer when using <UserControl.Resources>

  - by Mike Bynum

  Hi All, I'm tryihg to bind a combobox item source to a static resource. I'm oversimplfying my example so that it's easy to understand what i'm doing. So I have created a class public class A : ObservableCollection<string> { public A() { IKBDomainContext Context = new IKBDomainContext(); Context.Load(Context.GetIBOptionsQuery("2C6C1Q"), p => { foreach (var item in SkinContext.IKBOptions) { this.Add(item); } }, null); } } So the class has a constructor that populates itself using a domaincontext that gets data from a persisted database. I'm only doing reads on this list so dont have to worry about persisting back. in xaml i add a reference to the namespace of this class then I add it as a usercontrol.resources to the page control. <UserControl.Resources> <This:A x:Key="A"/> </UserControl.Resources> and then i use it this staticresource to bind it to my combobox items source.in reality i have to use a datatemplate to display this object properly but i wont add that here. <Combobox ItemsSource="{StaticResource A}"/> Now when I'm in the designer I get the error: Cannot Create an Instance of "A". If i compile and run the code, it runs just fine. This seems to only affect the editing of the xaml page. What am I doing wrong?

• Good DB Migrations for CakePHP?

  - by Martin Westin

  Hi, I have been trying a few migration scripts for CakePHP but I ran into problems with all of the in some form or another. Please advice me on a migration option for Cake that you use live and know works. I'd like the following "features": -Support CakePHP 1.2(e.g. CakeDCs migrations will only be an option when 1.3 is stable and my app migrated to the new codebase) -Support for (or at least not halt on) Models with a different database config. -Support Models in sub-folders of app/models -Support Models in plugins -Support tables that do not conform to Cake conventions (I have a few special tables that do not have a single primary key field and need to keep them) -Plays well with automated deployment via Capistrano and Git. I do not need rails-style versioned files a git versioned schema file that is compared live to the existing schema will do. That is: I like the SchemaShell in Cake apart from it not being compatible with most of my requirements above. I have looked at and tested: CakePHP Schema Shell http://book.cakephp.org/view/734/Schema-management-and-migrations CakeDC migrations http://cakedc.com/downloads/view/cakephp_migrations_plugin YAML migrations http://github.com/georgious/cakephp-yaml-migrations-and-fixtures joelmoss migrations http://code.google.com/p/cakephp-migrations

• Db4o Mvc Application Architecture

  - by Mac

  I am currently testing out Db4o for an asp.net MVC 2 application idea but there are a few things I'm not quite sure on the best way to proceed. I want my application to use guessable routes rather than Id's for referencing my entities but I also think I need Id's of some sort for update scenarios. so for example I want /country/usa instead of /country/1 I may want to change the key name though (not perhaps on a country but on other entities) so am thinking I need an Id to use as the reference to retrieve the object prior to updating it's fields. From other comments it seems like the UUID is a bit long to be using and would prefer to use my own id's anyway for clean separation of concerns. Looking at both the KandaAlpha project I wasn't too keen on some aspects of the design and prefer something more along the lines of S#arp architecture where they use things like the [domainsignature] and EntityWithTypedId, IEntityDuplicateChecker, IHasAssignedId, BaseObject and IValidatable in their entities to control insert/update behaviour which seems cleaner and more extensible, covers validation and is encapsulated well within the core and base repository classes. So would a port of S#arp architecture to Db4o make sense of am I still thinking rmdbs in an oodb world? Also is there a best practice for managing indexes (including Unique ones as above) in Db4o? Should they be model metadata based and loaded using DI in a bootstrapper for example or should they be more loaded more like Automapper.CreateMap? Its a bit of a rambling question I know but any thoughts, ideas or suggested reading material is greatly appreciated. Thanks Mac

• Virtual Earth (Bing) Pin "moves" when zoom level changes

  - by Ali

  Hi guys, Created a Virtual Earth (Bing) map to show a simple pin at a particular point. Everything works right now - the pin shows up, the title and description pop up on hover. The map is initially fully zoomed into the pin, but the STRANGE problem is that when I zoom out it moves slightly lower on the map. So if I started with the pin pointing somewhere in Toronto, if I zoom out enough the pin ends up i the middle of Lake Ontario! If I pan the map, the pin correctly stays in its proper location. When I zoom back in, it moves slightly up until it's back to its original correct position! I've looked around for a solution for a while, but I can't understand it at all. Please help!! Thanks a lot! import with javascript: http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2 $(window).ready(function(){ GetMap(); }); map = new VEMap('birdEye'); map.SetCredentials("hash key from Bing website"); map.LoadMap(new VELatLong(43.640144 ,-79.392593), 1 , VEMapStyle.BirdseyeHybrid, false, VEMapMode.Mode2D, true, null); var pin = new VEShape(VEShapeType.Pushpin, new VELatLong(43.640144 ,-79.392593)); pin.SetTitle("Goes to Title of the Pushpin"); pin.SetDescription("Goes as Description."); map.AddShape(pin);

• Getting the CVE ID Property of an update from WSUS API via Powershell

  - by thebitsandthebytes

  I am writing a script in Powershell to get the update information from each computer and correlate the information with another System which identifies updates by CVE ID. I have discovered that there is a "CVEIDs" property for an update in WSUS, which is documented in MSDN, but I have no idea how to access the property. Retrieving the CVE ID from WSUS is the key to this script, so I am hoping someone out there can help! Here is the property that I am having difficulty accessing: IUpdate2::CveIDs Property - http://msdn.microsoft.com/en-us/library/aa386102(VS.85).aspx According to this, the IUnknown::QueryInterface method is needed to interface IUpdate2 -  "http://msdn.microsoft.com/en-us/library/ee917057(PROT.10).aspx" "An IUpdate instance can be retrieved by calling the IUpdateCollection::Item (opnum 8) (section 3.22.4.1) method.  The client can use the IUnknown::QueryInterface method to then obtain an IUpdate2, IUpdate3, IUpdate4, or IUpdate5 interface. Additionally, if the update is a driver, the client can use the IUnknown::QueryInterface method to obtain an IWindowsDriverUpdate, IWindowsDriverUpdate2, IWindowsDriverUpdate3, IWindowsDriverUpdate4, or IWindowsDriverUpdate5 interface. " Here is a skeleton of my code: [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | Out-Null  if (!$wsus)  {  Returns an object that implements IUpdateServer  $wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer($server, $false, $port)  }  $computerScope = New-Object Microsoft.UpdateServices.Administration.ComputerTargetScope  $updateScope = New-Object Microsoft.UpdateServices.Administration.UpdateScope  $updateScope.UpdateSources = [Microsoft.UpdateServices.Administration.UpdateSources]::MicrosoftUpdate  $wsusMachines = $wsus.GetComputerTargets($computerScope)  foreach machine in QSUS, write the full domain name $wsusMachines | ForEach-Object {  Write-host $.FullDomainName  $updates = $.GetUpdateInstallationInfoPerUpdate($updateScope)  foreach update for each machine, write the update title, installation state and securitybulletin $updates | ForEach-Object {  $update = $wsus.GetUpdate($.UpdateId) # Returns an object that implements Microsoft.UpdateServices.Administration.IUpdate $updateTitle = $update.Title | Write-Host $updateInstallationState = $.UpdateInstallationState | Write-Host $updateSecurityBulletin = $update.SecurityBulletins | Write-Host  $updateCveIds = $update.CveIDs # ERROR: Property 'CveIDs' belongs to IUpdate2, not IUpdate  }  }

• Can I select 0 columns in SQL Server?

  - by Woody Zenfell III

  I am hoping this question fares a little better than the similar Create a table without columns. Yes, I am asking about something that will strike most as pointlessly academic. It is easy to produce a SELECT result with 0 rows (but with columns), e.g. SELECT a = 1 WHERE 1 = 0. Is it possible to produce a SELECT result with 0 columns (but with rows)? e.g. something like SELECT NO COLUMNS FROM Foo. (This is not valid T-SQL.) I came across this because I wanted to insert several rows without specifying any column data for any of them. e.g. (SQL Server 2005) CREATE TABLE Bar (id INT NOT NULL IDENTITY PRIMARY KEY) INSERT INTO Bar SELECT NO COLUMNS FROM Foo -- Invalid column name 'NO'. -- An explicit value for the identity column in table 'Bar' can only be specified when a column list is used and IDENTITY_INSERT is ON. One can insert a single row without specifying any column data, e.g. INSERT INTO Foo DEFAULT VALUES. One can query for a count of rows (without retrieving actual column data from the table), e.g. SELECT COUNT(*) FROM Foo. (But that result set, of course, has a column.) I tried things like INSERT INTO Bar () SELECT * FROM Foo -- Parameters supplied for object 'Bar' which is not a function. -- If the parameters are intended as a table hint, a WITH keyword is required. and INSERT INTO Bar DEFAULT VALUES SELECT * FROM Foo -- which is a standalone INSERT statement followed by a standalone SELECT statement. I can do what I need to do a different way, but the apparent lack of consistency in support for degenerate cases surprises me. I read through the relevant sections of BOL and didn't see anything. I was surprised to come up with nothing via Google either.

• displaying images in a list box so the image resizes based on parent container

  I have an expander with a list box in it that displays image thumbnails.

• Wpf Resource: "Unknown Build Error, 'Path cannot be null..."

  The following is a snippet from a xaml defining a DataGrid in a Control, defining a template selector. <DataGrid.Resources> <selector:CurrencyColorSelector x:Key="currencyColorSelector"> <selector:CurrencyColorSelector.NegativeTemplate> <DataTemplate> <TextBlock Text="{Binding Balance, StringFormat=n}" Background="Red"/> </DataTemplate> </selector:CurrencyColorSelector.NegativeTemplate> <selector:CurrencyColorSelector.NormalTemplate> <DataTemplate> <TextBlock Text="{Binding Balance, StringFormat=n}"/> </DataTemplate> </selector:CurrencyColorSelector.NormalTemplate> </selector:CurrencyColorSelector> </DataGrid.Resources> Now, an error is thrown: "Unknown build error, 'Path cannot be null. Parameter name: path Line 27 Position 79.'" (Compiler or xaml validation error). I have no idea where this Path comes from, neither does my example show anything of it. If you doubleclick the error, it points to the end of the first line. Did anybody encounter such a problem and has a solution for it?

• Manipulating columns of numbers in elisp

  - by ~unutbu

  I have text files with tables like this: Investment advisory and related fees receivable (161,570 ) (71,739 ) (73,135 ) Net purchases of trading investments (93,261 ) (30,701 ) (11,018 ) Other receivables 61,216 (10,352 ) (69,313 ) Restricted cash 20,658 (20,658 ) - Other current assets (39,643 ) 14,752 64 Other non-current assets 71,896 (26,639 ) (26,330 ) Since these are accounting numbers, parenthesized numbers indicate negative numbers. Dashes represent 0 or no number. I'd like to be able to mark a rectangular region such as third column above, call a function (format-column), and automatically have (-73135-11018-69313+64-26330)/1000 sitting in my kill-ring. Even better would be -73.135-11.018-69.313+0.064-26.330 but I couldn't figure out a way to transform 64 -- 0.064. This is what I've come up with: (defun format-column () "format accounting numbers in a rectangular column. format-column puts the result in the kill-ring" (interactive) (let ((p (point)) (m (mark)) ) (copy-rectangle-to-register 0 (min m p) (max m p) nil) (with-temp-buffer (insert-register 0) (goto-char (point-min)) (while (search-forward "-" nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward "," nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward ")" nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward "(" nil t) (replace-match "-" nil t) (just-one-space) (delete-backward-char 1) ) (goto-char (point-min)) (while (search-forward "\n" nil t) (replace-match " " nil t)) (goto-char (point-min)) (kill-new (mapconcat 'identity (split-string (buffer-substring (point-min) (point-max))) "+")) (kill-region (point-min) (point-max)) (insert "(") (yank 2) (goto-char (point-min)) (while (search-forward "+-" nil t) (replace-match "-" nil t)) (goto-char (point-max)) (insert ")/1000") (kill-region (point-min) (point-max)) ) ) ) (global-set-key "\C-c\C-f" 'format-column) Although it seems to work, I'm sure this function is poorly coded. The repetitive calls to goto-char, search-forward, and replace-match and the switching from buffer to string and back to buffer seems ugly and inelegant. My entire approach may be wrong-headed, but I don't know enough elisp to make this more beautiful. Do you see a better way to write format-column, and/or could you make suggestions on how to improve this code?

Here's what my code looks like: <!-- this is in <head> --> <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="http://api.recaptcha.net/js/recaptcha_ajax.js"></script> <script type="text/javascript"> $(document).ready(function() { Recaptcha.create("my key here", "recaptcha_widget", { "theme": "custom", "lang": "en", "callback": function() { console.log("callback"); } // this doesn't get called }); }); </script> <!-- ... this is in <body> --> <div id="recaptcha_widget" style="display: none"> <div id="recaptcha_image"></div> <div id="recaptcha_links"> <a href="javascript:Recaptcha.reload()">get another</a> &bull; <a class="recaptcha_only_if_image" href="javascript:Recaptcha.switch_type('audio')">switch to audio</a> <a class="recaptcha_only_if_audio" href="javascript:Recaptcha.switch_type('image')">switch to image</a> &bull; <a href="javascript:Recaptcha.showhelp()">help</a> </div> <dt>Type the words</dt> <dd><input type="text" id="recaptcha_response_field" name="recaptcha_response_field"></dd> </div>

• Fluent NHibernate IDictionary with composite element mapping

  - by Alessandro Di Lello

  Hi there, i have these 2 classes: public class Category { IDictionary<string, CategoryResorce> _resources; } public class CategoryResource { public virtual string Name { get; set; } public virtual string Description { get; set; } } and this is xml mapping <class name="Category" table="Categories"> <id name="ID"> <generator class="identity"/> </id> <map name="Resources" table="CategoriesResources" lazy="false"> <key column="EntityID" /> <index column="LangCode" type="string"/> <composite-element class="Aca3.Models.Resources.CategoryResource"> <property name="Name" column="Name" /> <property name="Description" column="Description"/> </composite-element> </map> </class> and i'd like to write it with Fluent. I found something similar and i was trying with this code: HasMany(x => x.Resources) .AsMap<string>("LangCode") .AsIndexedCollection<string>("LangCode", c => c.GetIndexMapping()) .Cascade.All() .KeyColumn("EntityID"); but i dont know how to map the CategoryResource entity as a composite element inside the Category element. Any advice ? thanks

• Iterating through StaticResource loaded by ResourceDictionary

  - by akaphenom

  Given a resource dictionary loading some static resources into memory - is there any way to iterate through theResources loaded into memory? My silverlight application keeps telling me it cannot find a static resource. I wonder if I have a naming convention issue or somehting - was hoping iterating through the resources in memory would help diagnose any issue... I have the following app.xaml <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Module1.MyApp"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/FSSilverlightApp;component/TransitioningFrame.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> and content template: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ControlTemplate x:Key="TransitioningFrame" TargetType="navigation:Frame"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}"/> </Border> </ControlTemplate> </ResourceDictionary>

• How to use perl for SMTP connection with user and SSL Auth and send emails with attachment

  - by Octopus

  I am using a SMTP mail server which require user + ssl authentication for connection. I am looking for the perl modules to connect to the mail server and send emails but doesn't found anything helpful. Any suggestion for perl module or any perl code would be really appreciated. EDIT I have tried to use Mail::Sendmail and Net::SMTP::SSL to connect to the sendmail server and send mail. Below is the sample code but getting the error user unknown. Error: mail: Net::SMTP::SSL=GLOB(0x9599850) not found RCPT TO: error (550 5.1.1 <[email protected]>... User unknown). Code: #!/usr/bin/perl use strict; use warnings; use Mail::Sendmail; use Net::SMTP::SSL; my %mail = ( #To=> 'No to field this time, only Bcc and Cc', From=> '[email protected]', Cc=> '[email protected]', # Cc will appear in the header. (Bcc will not) Subject => 'Test message', 'X-Mailer' => "Mail::Sendmail version $Mail::Sendmail::VERSION", ); $mail{Smtp} = Net::SMTP::SSL->new("mail.server.com", Port=> 465); $mail{auth} = {user=>'username', password=>"password", required=>1 }; $mail{'X-custom'} = 'My custom additionnal header'; $mail{Message} = "The message key looks terrible, but works."; # cheat on the date: $mail{Date} = Mail::Sendmail::time_to_date( time() - 86400 ); if (sendmail %mail) { print "Mail sent OK.\n" } else { print "Error sending mail: $Mail::Sendmail::error \n" } print "\n\$Mail::Sendmail::log says:\n", $Mail::Sendmail::log;

• VS2008 EF and non crud SP usage.

  - by SteveO

  Using an edmx version of EF. My returned data is a join between tables that has a COMPOUND filter on the primary table. In essence this query is going to return a SEGMENT of Law codes and descriptions that a user can tie to a Sex Offender report. I have a complex SP because Linq2SQL cannot pass in a between statement, or at least that is how I understand the error. The Code itself is broken up by '-' marks. 39-13-504 "Aggravated Sexual Battery" User wants to have a query with 4 parmas 39, 13, 500, 599. Get all codes from Title 39 and Chapter 13 with parts between 500 and 599. I have the SP in place to do the work, is there are way to consume the SP within the EF? I find many blogs about SPs with CRUD operations as their use of an SP. That doesn't fit this need at all. I do not have a single table but a join to the "prior selections" table that maps the key for the code. Any pointers on how to get a READ with an SP? TIA

• Server port 16080 problem: webserver adds the port number 16080 in the URL

  - by Juri

  Hello everybody. On my wordpress website one little thing doesn't work. Sometimes the Webserver adds the port number 16080 in the URL, which leads to an error (network timeout). Wrong: http://www.example.com:16080/about-us/weekly-program/?month=may&yr=2010 Correct: http://www.example.com/about-us/weekly-program/?month=may&yr=2010 Has someone a "Server port 16080 problem fix"? Is it possible, that I need to add a ServerName directive to the config file to tell the domain name of the server? Cheers Juri !!!update!!! PS: Here is the site configuration, don't ask me to change the 16080 to 80, because that screwes up everyone else's websites...

• maintaining a large list in python

  - by Oren

  I need to maintain a large list of python pickleable objects that will quickly execute the following algorithm: The list will have 4 pointers and can: Read\Write each of the 4 pointed nodes Insert new nodes before the pointed nodes Increase a pointer by 1 Pop nodes from the beginning of the list (without overlapping the pointers) Add nodes at the end of the list The list can be very large (300-400 MB), so it shouldnt be contained in the RAM. The nodes are small (100-200 bytes) but can contain various types of data. The most efficient way it can be done, in my opinion, is to implement some paging-mechanism. On the harddrive there will be some database of a linked-list of pages where in every moment up to 5 of them are loaded in the memory. On insertion, if some max-page-size was reached, the page will be splitted to 2 small pages, and on pointer increment, if a pointer is increased beyond its loaded page, the following page will be loaded instead. This is a good solution, but I don't have the time to write it, especially if I want to make it generic and implement all the python-list features. Using a SQL tables is not good either, since I'll need to implement a complex index-key mechanism. I tried ZODB and zc.blist, which implement a BTree based list that can be stored in a ZODB database file, but I don't know how to configure it so the above features will run in reasonable time. I don't need all the multi-threading\transactioning features. No one else will touch the database-file except for my single-thread program. Can anyone explain me how to configure the ZODB\zc.blist so the above features will run fast, or show me a different large-list implementation?
