• SSIS 2008 Rows per batch and Maximum insert commit size

  - by Nissan Fan

  I've got about 100 million rows that I'm moving in SSIS 2008 via a Data Flow Task. It's pretty much a straight table data copy using a Multicast. My question is this: Using the OLE DB Destination Editor I have two options: Rows per batch and Maximum insert commit size. What are good settings for this? I've only been able to find that you are recommended to set Maximum insert commit size to 2147483647 instead of 0, but then tweak both these settings based on testing. I'm curious to find out if anyone has discovered anything useful in their own management of these values.

• Using CHDataStructures.framework on iPhone

  - by nununo

  Hi, I'm new to iPhone programming and I'm trying to use CHDataStructures in my project. But I'm running into some issues: When I directly try to build it right after download I get the error "Foundation/Foundation.h" no such file or directory. The Active SDK is "Use Base SDK" and the active architecture is x86_64. I believe I should set the Active SDK to the iPhone SDK but it isn't listed there; At some point (I don't remember how) I managed to tweak it and I got the iPhone SDK (simulator) in the active SDK but when I tried to build it I got the following error: "target specifies product type 'com.apple.product-type.framework', but there's no such product type for the 'iphonesimulator' platform"; And now I'm stuck. What am I doing wrong? Thanks in advance, Nuno

• Entity Framework One-To-One Mapping Issues

  - by Baddie

  Using VS 2010 beta 2, ASP.NET MVC. I tried to create an Entity framework file and got the data from my database. There were some issues with the relationships, so I started to tweak things around, but I kept getting the following error for simple one-to-one relationships Error 1 Error 113: Multiplicity is not valid in Role 'UserProfile' in relationship 'FK_UserProfiles_Users'. Because the Dependent Role properties are not the key properties, the upper bound of the multiplicity of the Dependent Role must be *. myEntities.edmx 2024 My Users table is consists of some other many-to-many relationships to other tables, but when I try to make a one-to-one relationship with other tables, that error pops up. Users Table UserID Username Email etc.. UserProfiles Table UserProfileID UserID (FK for Users Table) Location Birthday

• HTML table headers always visible at top of window when viewing a large table

  - by Craig McQueen

  I would like to be able to "tweak" an HTML table's presentation to add a single feature: when scrolling down through the page so that the table is on the screen but the header rows are off-screen, I would like the headers to remain visible at the top of the viewing area. This would be conceptually like the "freeze panes" feature in Excel. However, an HTML page might contain several tables in it and I only would want it to happen for the table that is currently in-view, only while it is in-view. Note: I've seen one solution where the table data area is made scrollable while the headers do not scroll. That's not the solution I'm looking for.

• vb.net program cannot connect to wampserver

  - by user225269

  I have a vb.net program that uses mysql as its database. And it works when the computer has wampservr installed. But the program gets an unhandled exception error when the computer where its running does not have a wampserver. The only thing that is installed in it is the mysql connector net. How do I make it work. I just want the two programs to access the same mysql database. I already opened port 20 by configuring firewall. Both in TCP and UDP. What do I do? Do I have to tweak the codes?

• Why won't the VisualVM Profiler profile my application?

  - by Luke

  I've created a simple 1 file java application that iterates through a loop, calls some functions, allocates some memory, adds some numbers, etc. I run that application via eclipse's Run As->Java Application. The running application shows up in Java VisualVM under Local. I double click on that application and go to the Profiler tab. The default settings are: Start profiling from classes: my.main.package.** Do not profile classes: java.*, javax.*, sun.*, sunw.*, com.sun.* I click on CPU. The CPU and Memory buttons gray out. Nothing happens. The Status says profiling inactive. When my application terminates the Status says application terminated. What am I doing wrong here? Are there some settings I need to tweak? Do I need to set a VM flag when I launch my application?

• Are there any PHP DocBlock parser tools available?

  - by Beau Simensen

  I would like to build some smaller scale but hightly customized documentation sites for a few projects. PhpDocumentor is pretty great but it is very heavy. I thought about trying to tweak the templates for that but after spending only a couple of minutes looking into it I decided that it would be too much work. Ideally I'd like to see something to which I could pass a bunch of files and have it return all of the files, classes and properties and methods, along with their meta data, so that I could build out some simple templates based on the data. Are there any DocBlock parser-only projects that will help me in this task, or am I stuck reinventing that wheel?

• Update frequency for dynamic favicons

  - by rosscowar

  I wanted to learn how to dynamically update the favicon using the Google Chrome browser and I've noticed that the browser seems to throttle how often you can update the favicon per second and that sort of makes things look sloppy. The test page I've made for this is: http://staticadmin.com/countdown.html Which is simply a scrolling message displaying the results of a countdown. I added an input field to tweak how many pixels per second are moved by the script and I've eyeballed the max to be about 5 frames per second smoothly in Google Chrome and I have not tested it in any other browsers. My question is what is the maximum frequency, are there any ways to change, is there a particular reason behind it? NOTE: I've also noticed that this value changes based on window focus as well. It seems to drop to about 1 update per second when the browser's window isn't in focus and returns to "max" when you return.

• iPhone: Having trouble figuring out how to scroll a UITableView with custom UITextField cells automa

  - by Gordon Fontenot

  Ok, I know this seems like a duplicate question, but don't think it is. I actually have this implemented already (thanks to this SO question), but it seems sluggish. I am willing to tweak it a bit, but I ran across a demo app by AboutObjects that seems to have exactly the right functionality with absolutely no code doing it. I have looked through their demo code dozens of times, and I can't figure out what they are doing that I am not. The code to look at is in their iPhone Development Tutorials section, and is called "Editable TableView" (2nd from the bottom). There are a couple of questions on the forums on that site asking how they got the functionality, but there is no answer (other than "It's a built in function"). Does anyone have any clue as to why their UITableView would implement the input scrolling by default (including being able to scroll the view manually when the keyboard pops up, which I cannot get to work)?

• Suggestions for debugging print stylesheets?

  - by Jim Puls

  I've recently been working on a print stylesheet for a website, and I realized that I was at a loss for effective ways to tweak it. It's one thing to have a reload cycle for working on the on-screen layout: change code command-tab reload but that whole process gets much more arduous when you're trying to print: change code command-tab reload print squint at print-preview image open PDF in Preview for further inspection Are there tools I'm missing out on here? Does WebKit's inspector have a "pretend this is paged media" checkbox? Is there some magic that Firebug (shudder) can do?

• Measuring Web Page Performance on Client vs. Server

  - by Yaakov Ellis

  I am working with a web page (ASP.net 3.5) that is very complicated and in certain circumstances has major performance issues. It uses Ajax (through the Telerik AjaxManager) for most of its functionality. I would like to be able to measure in some way the amounts of time for the following, for each request: On client submitting request to server Client-to-Server On server initializing request On server processing request Server-to-Client Client rendering, JavaScript processing I have monitored the database traffic and cannot find any obvious culprit. On the other hand, I have a suspicion that some of the Ajax interactions are causing performance issues. However, until I have a way to track the times involved, make a baseline measurement, and measure performance as I tweak, it will be hard to work on the issue. So what is the best way to measure all of these? Is there one tool that can do it? Combination of FireBug and logging inserted into different places in the page life-cycle?

• Linking to non-home panel in JQTouch site

  - by Patrick Dinnen

  I'm trying to create a link from an external site that arrives at a particular, internal panel on a JQTouch site I'm building. However the browser always opens the home panel of the JQT site no matter what anchor tag I use in the link. e.g. If I try to link to the User Interface panel in the official JQTouch demo I use http://www.jqtouch.com/preview/demos/main/#ui but the home panel shows in the browser and not the sub-panel I requested. Any suggestions would be very welcome. I have control of the both the linked and linking sites so can tweak code is necessary. Thanks

• Is there a Windows API to modify file type associations for an extension?

  - by JohnFx

  I'm looking for a way to programatically tweak the particulars of a file association on a Windows system. For example, the "Application User to Perform this Action" setting for the "Open" action for a particular file type. Clearly I could do this by modifying the registry directly, but if there is an API I'd prefer to use that as it would likely be more resilient to changes in the OS handling of mapping extensions to applications. For my purposes I'm needing to write this in VBScript (.VBS) file because it is part of a package to be used with VMWare ThinApp that mandates it. However, I'll port/wrap/whatever I need to make this week, so I am open to any solution (including using the .NET framework)

• Opera Mobile for Windows + Reported Screen Size

  - by Antony Scott

  I know this isn't a direct programming question, but's it's kinda relevant as I'm trying to get a good testing environment set up before I embark on my latest project. I'm trying to set up Opera Mobile for Windows to allow me to test a new website. The UserAgent I get is a fairly generic one, so my workaround is to tweak my mobile.browser file to have the correct screen width and height of the target device. Is it possible to add to the list of "fake" user agents that Opera Mobile for Windows can pretend to be? It currently supports S60, Android and Windows Mobile.

• Graph visualization code in javascript?

  - by Chris Farmer

  Hi. I have a data structure that represents a directed graph, and I want to render that dynamically on an HTML page. Does anyone know of any javascript code that can do a reasonable job with graph layout? These graphs will usually be just a few nodes, maybe ten at the very upper end, so my guess is that performance isn't going to be a big deal. Ideally, I'd like to be able to hook it in with jQuery so that users can tweak the layout manually by dragging the nodes around. Edit: Google's Visualization API seems to be more "graphs as charts" oriented than "graphs as nodes" oriented. I didn't see any node-oriented visualizations already built there, anyway. Do you know that one exists?

• Regex: Strip HTML attributes except SRC

  - by Ian Silber

  Hi, I'm trying to write a regular expression that will strip all tag attributes except for the SRC attribute. For example: <p id="paragraph" class="green">This is a paragraph with an image <img src="/path/to/image.jpg" width="50" height="75"/></p> Would be returned as: <p>This is a paragraph with an image <img src="/path/to/image.jpg" /></p> I have a regular expression to strip all attributes, but I'm trying to tweak it to leave in src. Here's what I have so far: <?php preg_replace('/<([A-Z][A-Z0-9]*)(\b[^>]*)>/i', '<$1>', '<html><goes><here>'); Using PHP's preg_replace() for this. Thanks! Ian

• .NET Regular Expression to split multiple words or phrases

  - by Cj Anderson

  I'm using the code below to take a string and split it up into an array. It will take: Disney Land and make it two separate elements. If the string contains "Disney Land" then it is one element in the array. Works great, however it adds some empty elements to the array each time. So I just iterate over the elements and remove them if they are empty. Is there a tweak to the code below that will prevent those empty elements from occurring? Private m_Reg As Regex m_Reg = New Regex("([^""^\s]+)\s*|""([^""]+)""\s*") Dim rezsplit = m_Reg.Split(criteria)

• Any Way to Further Customize Embedded Google Calendar?

  - by user117737

  I'd like to embed a few Google Calendars for my client's web site. The "Google Embeddable Calendar Helper" provides very few customization options. Updating the hex code for the background color in the generated source only works if you pick one of the ~70 standard Google Calendar bg colors. (I can tweak the "border" selector because at least it's in an actual statement.) A "view-source" on the rendered page shows a CSS file loaded from the iframe, but I obviously can't change anything in there. And I assume I can't force an override of selectors with my own CSS file because I have no way of "injecting" it into the iframe. Does anyone know of a (non-API) way of tweaking the colors, fonts, and other CSS thingies in an embedded Google Calendar? Thanks in advance...

• memory problem with metapost

  - by yCalleecharan

  Hi, I'm using gnuplot to plot a graph to the mp format and then I'm converting it to eps via the command: mpost --sprologues=3 -soutputtemplate=\"%j-%c.eps\" myfigu.mp But I don't get the eps output; instead I get this message: This is MetaPost, version 1.208 (kpathsea version 3.5.7dev) (mem=mpost 2009.12.12) 6 MAY 2010 23:16 **myfigu.mp (./myfigu.mp !

The text file containing these two column values is about 6 MB. Thanks a lot...

• PHP protected classes and properties, protected from whom?

  - by Andrew Heath

  I'm just getting started with OOP PHP via PHP Object-Oriented Solutions and am a little curious about the notion of protection in OOP. The author clearly explains how protection works, but the bit about not wanting others to be able to change properties falls a bit flat. I'm having a hard time imagining a situation where it is ever possible to prevent others from altering your classes, since they could just open up your class.php and manually tweak whatever they pleased seeing as how PHP is always in plaintext. Caution: all of the above written by a beginner with a beginner's understanding of programming...

• Swapping an image during web development

  - by detly

  I'm trying to see what a certain webpage would look like if I replaced a certain image with another. Rather than upload the image, edit the site, etc, each time I tweak it, I'd like to know if there's a way to change the image in the page to my local version while viewing the remote page. I use Firebug for debugging web development usually, but I'm open to any other tool that might do this. (It is absolutely impossible to search for this and find anything but questions about dynamic image swapping on a deployed website, so sorry if this is a duplicate.)

• Generate markdown from source code doc-comments

  - by erikkallen

  Is there any easy way to generate markdown from source code comments? I'm looking for something similar to Sandcastle, but with Markdown (or something like it) as output. The full story is that I use DokuWiki to generate documentation. It has many nice properties, including that all its data is stored in text files. So my idea is that I should somehow be able to get my API docs into the same place as the rest of my documentation. So far my best bet seems to be to write a custom documenter for NDoc3, but perhaps someone has already done something similar which would save me the trouble. I realize I might need to tweak it a little due to slight syntax differences.

• In Delphi, Is there a way to adjust the line spacing of a TMemo?

  - by Kieran

  I'm working with a TMemo component to display some text in a limited space. Currently it's using a truetype font which doesn't ship with windows and is installed by the app when it runs. On my PC (Running Windows XP), the spacing between each line of text seems to be about eight pixels. On a different PC running Windows 7, the line spacing seems to be about 14 pixels, which is pushing the bottom row of text out of visibility on the memo. So, My question is really this: Is this caused by the different versions of Windows? It's all I could think that was different. Is there some way I can adjust this value so it would be consistent across all instances of the application, wherever it was running? Alternatatively, is there a different component I could use which might let me tweak this value?

• Deploy CakePHP to a subfolder

  - by mgroves

  I have created a CakePHP 2 app, and now I'm trying to deploy it to a production web server. My app uses the default folder structure (app/lib/plugins/vendors), default htaccess, default routing, nothing special. I've been developing locally as if the app were in the root folder of the site (e.g. http://mycakeapp.localhost/ takes me to the site). But I'm deploying to a site (shared hosting) where that will not be the case (e.g. http://www.somedomain.com/mycakeapp). It doesn't work (I didn't really expect it to), so I assumed I had to tweak one or more htaccess files. I tried modifying the root .htaccess as suggested in this post, but that only partially worked (the link to the CSS didn't work, for instance): <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^mycakeapp$ mycakeapp/app/webroot/ [L] RewriteRule ^mycakeapp/(.*)$ mycakeapp/app/webroot/$1 [L] </IfModule> So what should I do to all the htaccess files to make this CakePHP site work in a subfolder?

• Placing an background image with padding in h2 tag

  - by Cedar Jensen

  I want to create a headline (h2) with an image at the right-most area of the bounding box. I have the layout almost right except I can't push the image a little bit to the right of the element's bounding box -- how would I tweak my css so it is displayed correctly? I'm trying to do something like this: [{someHeadLineText}{dynamic space }{image}{5px space}] where the [] indicate the total available width of my content. Html: <div class="primaryHeader"> <h2>News</h2> </div> Css: .primaryHeader h2 { background-color: green; /* the header looks like a box */ color: black; background: transparent url(../images/edit.png) no-repeat right center; border: 1px solid red; } I am placing the image to the right of my h2 element and centered vertically -- but how do I adjust the placement of the background image?
