  • fileinfo and mime types I've never heard of

    - by Jim
    I'm not a stranger to mime types but this is strange. Normally, a text file would have been considered to be of text/plain mime but now, after implementing fileinfo, this type of file is now considered to be "text/x-pascal". I'm a little concerned because I need to be sure that I get the correct mime types set before allowing users to upload with it. Is there a cheat sheet that will give me all of the "common" mimes as they are interpreted by fileinfo? Sinan provided a link that lists all of the more common mimes. If you look at this list, you will see that a .txt file is of text/plain mime but in my case, a plain-jane text file is interpreted as text/pascal.

  • C# Application Becomes Slow and Unresponsive as String in Multiline Textbox Grows

    - by Jim Fell
    Hello. I have a C# application in which a LOT of information is being added to a Textbox for display to the user. Upon processing of the data, almost immediately, the application becomes very slow and unresponsive. This is how I am currently attempting to handle this: var saLines = textBox1.Lines; var saNewLines = saLines.Skip(50); textBox1.Lines = saNewLines.ToArray(); This code is run from a timer every 100mS. Is there a better way to handle this? I am using Microsoft Visual C# 2008 Express Edition. Thanks.

  • Auto-Complete Suggestions in Source Code Editor

    - by Jim
    Hello, Most IDEs (Eclipse, Netbeans, Intelij) provide contextually smart suggestions about the current statement you're writing. We would like to do the same thing (In Java for Java). We considered tokenizing the input and building our own abstract syntax trees, but quickly realized that could be a month long project in and of its self. We also started digging through the source code for the above mentioned IDEs, but it appears (correct me if I'm wrong) that the auto-complete code is pretty tightly woven with the rest of the IDE. We're wondering if anyone knows of a relatively isolated package that we could pull into our project to provide this auto-complete functionality. Thanks!

  • Python os.path.join

    - by Jim
    Hello, I am trying to learn python and am making a program that will output a script. I want to use os.path.join but am pretty confused (I know I am very bad at scripting/programming) See, according to the docs ( http://docs.python.org/library/os.path.html ) if I say os.path.join('c:', 'sourcedir') I get C:sourcedir as it's output. According to the docs, this is normal (right?) But when I use the copytree command, Python will output it the desired way, for example import shutil src = os.path.join('c:', 'src') dst = os.path.join('c':', 'dst') shutil.copytree(src, dst) Here is the error code I get WindowsError: [Error 3] The system cannot find the path specified: 'C:src/.' If I wrap the os.path.join with os.path.normpath I get the same error If this os.path.join can't be used this way, then I am confused as to its purpose According to the pages suggested by Stack Overflow, slashes should not be used in join--that is correct I assume? Thanks guys(girls) for your help

  • MVC 4 Beta with Mobile Project FIle Upload does not work

    - by Jim Shaffer
    I am playing around with the new MVC 4 beta release. I created a new web project using the Mobile Application template. I simply added a controller and a view to upload a file, but the file is always null in the action result. Is this a bug, or am I doing something wrong? Controller Code: using System.IO; using System.Web; using System.Web.Mvc; namespace MobileWebExample.Controllers { public class FileUploadController : Controller { public ActionResult Index() { return View(); } [AllowAnonymous] [HttpPost] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Upload(HttpPostedFileBase file) { int i = Request.Files.Count; if (file != null) { if (file.ContentLength > 0) { var fileName = Path.GetFileName(file.FileName); var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName); file.SaveAs(path); } } return RedirectToAction("Index"); } } } And the view looks like this: @{ ViewBag.Title = "Index"; } <h2>Index</h2> <form action="@Url.Action("Upload")" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <input type="submit" value="Submit" /> </form>

  • Stacking two pictures with captions side by side and centered in Wordpress

    - by Jim
    Hi all - this is driving me absolutely nuts. I'm not the most experienced with CSS, so I'm hoping it is something simple. I'm running Wordpress 2.9.2 with "The Morning After" theme. I am trying to write a post where I want to display two small pictures, with captions, side-by-side and centered in the middle of the page. Here is the HTML code I am using to display the images: [caption align="alignnone" width="150" caption="Protein rest"] <a href="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest.jpg"> <img title="Mash during protein rest" src="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest-150x144.jpg" alt="Mash during protein rest" width="150" height="144" /> </a>[/caption] [caption align="alignnone" width="143" caption="Saccharification rest" captionalign="center"] <a href="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest.jpg"> <img title="Mash during saccharification rest" src="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest-143x150.jpg" alt="Mash during saccharification rest" width="143" height="150" /> </a>[/caption] I tried using "aligncenter" and "alignleft" for the caption align - if I use "alignleft" the pictures are lined up perfectly, but all the way to the left of the page. If I use "aligncenter" the pics are in the center, but stacked one on top of the other. My first thought was to wrap the images in a div using: <div style="text-align:center;">image code</div> but that doesn't work. Now, if I wrap in a centered div like that and omit the [caption] tags, it works, but I need the captions. Those caption tags are translated by Wordpress into it's own div of class wp-caption. I've also tried wrapping each separate image in its own div within a parent centered div wrapper. Here is the pertinent parts of the style.css - please let me know if you need any other info, and if you can help me, I will postpone jumping off the nearest bridge! Thanks!! Style.css: .aligncenter, div.aligncenter { display: block; margin: 14px auto; } .alignleft { float: left; margin: 0 14px 10px 0; } .alignright { float: right; margin: 0 0 10px 14px; } .wp-caption { border: 1px solid #ddd; text-align: center; background-color: #f3f3f3; padding-top: 4px; /* optional rounded corners for browsers that support it */ -moz-border-radius: 3px; -khtml-border-radius: 3px; -webkit-border-radius: 3px; border-radius: 3px; } .wp-caption img { margin: 0; padding: 0; border: 0 none; } .wp-caption p.wp-caption-text { font-size: 11px; line-height: 14px; padding: 5px 4px 5px 5px; margin: 0; } PS - I am aware of the Gallery feature available in Wordpress, but would like to avoid it and would love to understand why wrapping in a div doesn't move the whole kit to the center. Finally, just for the sake of completeness, here is the source of the page when loaded using the div wrapper and image code as above (so you can see how Wordpress translates the caption tags): <div style="text-align:center;"> <div class="wp-caption alignnone" style="width: 160px"> <a href="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest.jpg"> <img title="Mash during protein rest" src="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest-150x144.jpg" alt="Mash during protein rest" width="150" height="144" /> </a> <p class="wp-caption-text" style="text-align:center">Protein rest</p> </div> <div class="wp-caption alignnone" style="width: 153px"> <a href="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest.jpg"> <img title="Mash during saccharification rest" src="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest-143x150.jpg" alt="Mash during saccharification rest" width="143" height="150" /> </a> <p class="wp-caption-text" style="text-align:center">Saccharification rest</p> </div> </div>

  • Grouping php array items based on user and created time

    - by Jim
    This is an array of objects showing a user uploading photos: Array ( [12] => stdClass Object ( [type] => photo [created] => 2010-05-14 23:36:41 [user] => stdClass Object ( [id] => 760 [username] => mrsmith ) [photo] => stdClass Object ( [id] => 4181 ) ) [44] => stdClass Object ( [type] => photo [created] => 2010-05-14 23:37:15 [user] => stdClass Object ( [id] => 760 [username] => mrsmith ) [photo] => stdClass Object ( [id] => 4180 ) ) ) However instead of showing: mr smith uploaded one photo mr smith uploaded one photo I'd like to display: mr smith uploaded two photos by grouping similar items, grouping by user ID and them having added them within, let's say 15 minutes of each other. So I'd like to get the array in this sort of shape: Array ( [12] => stdClass Object ( [type] => photo [created] => 2010-05-14 23:36:41 [user] => stdClass Object ( [id] => 760 [username] => mrsmith ) [photos] => Array ( [0] => stdClass Object ( [id] => 4181 ) [1] => stdClass Object ( [id] => 4180 ) ) ) ) preserving the first item of the group and it's created time, and supplementing it with any other groupable photos and then unsetting any items that were grouped (so the final array doesn't have key 44 anymore as it was grouped in with 12). The array contains other actions than just photos, hence the original keys of 12 and 44. I just can't figure out a way to do this efficiently. I used to use MySQL and PHP to do this but am trying to just use pure PHP for caching reasons. Can anyone shed any insights? I thought about going through each item and seeing if I can group it with the previous one in the array but the previous one might not necessarily be relevant or even a photo. I've got total brain freeze :(

  • SVN Path Based Authorization: Granting listing access but not read access

    - by Jim
    Hello, We're using path-based-authorization module for Apache SVN. It all works fine, except that when users try to check out code they have access to, their SVN clients get confused if they don't have at least read access to the parent directories - all the way up to root. It works, but some clients just get confused sometimes. Because SVN path-based-authorization is recursively applied, we don't want to give all users read access to root, because that would give them access to all source code in the repository. It would, however, be acceptable if users could get directory listings (just not actual lines of code) for the entire repository. This would prevent the svn clients from getting confused. Does any one know how to grant permissions to get directory listings without granting permissions to the actual contents of the files? Thanks!

  • How to think in data stores instead of databases?

    - by Jim
    As an example, Google App Engine uses data stores, not a database, to store data. Does anybody have any tips for using data stores instead of databases? It seems I've trained my mind to think 100% in object relationships that map directly to table structures, and now it's hard to see anything differently. I can understand some of the benefits of data stores (e.g. performance and the ability to distribute data), but some good database functionality is sacrificed (e.g. joins). Does anybody who has worked with data stores like BigTable have any good advice to working with them?

  • Creating BlackBerry method stubs using wscompile on WSDL from ColdFusion

    - by Jim B
    I have been working on a BlackBerry application that consumes web services from ColdFusion 7. The Java ME SDK and the Java Wireless Toolkit both require that the generated WSDL be of the document/literal type. Fortunately, I have input on the web service development so I tried setting 'style="document"' in the cfcomponent tag. This generated a document/literal style WSDL but now wscompile generates the following errors in several places: Found unknown simple type: javax.xml.soap.SOAPElement Found unknown simple type: java.util.Calendar Any ideas why this is happening? The WSDL does get parsed correctly by the JWSDP tool but the stubs use namespaces that are not available in the J2ME platform. I would have thought ColdFusion WSDL would work more easily with other products in the Java family.

  • What data formats does PowerShell most easily read ?

    - by Jim
    I'm trying to use PowerShell with SharePoint. I'd like my PowerShell scripts to load my SharePoint farm configuration from files rather than either hard coding the configuration in the scripts, or having to pass in the same parameters each time. This the kind of information I need to store. WebFrontEnds: Web1, Web2, Web3 CentralAdmin: Central1 Index: Web1 ContentWebApps: http://user1, http://user2 Does PowerShell easily load this data from CSV, XML, or other formats?

  • ClassLoader exceptions being memoized

    - by Jim
    Hello, I am writing a classloader for a long-running server instance. If a user has not yet uploaded a class definition, I through a ClassNotFoundException; seems reasonable. The problem is this: There are three classes (C1, C2, and C3). C1 depends on C2, C2 depends on C3. C1 and C2 are resolvable, C3 isn't (yet). C1 is loaded. C1 subsequently performs an action that requires C2, so C2 is loaded. C2 subsequently performs an action that requires C3, so the classloader attempts to load C3, but can't resolve it, and an exception is thrown. Now C3 is added to the classpath, and the process is restarted (starting from the originally-loaded C1). The issue is, C2 seems to remember that C3 couldn't be loaded, and doesn't bother asking the classloader to find the class... it just re-throws the memoized exception. Clearly I can't reload C1 or C2 because other classes may have linked to them (as C1 has already linked to C2). I tried throwing different types of errors, hoping the class might not memoize them. Unfortunately, no such luck. Is there a way to prevent the loaded class from binding to the exception? That is, I want the classloader to be allowed to keep trying if it didn't succeed the first time. Thanks!

  • Calculating ComboBox DropDownWidth in C#

    - by Jim Fell
    In my application a ComboBox gets resized, so that it is smaller. How do I re-calculate the DropDownWidth property? I know how to set it, but I'd prefer to calculate the proper width because its contents changes. Preferabley, I was thinking of something along these lines: int iMaxLen = 0; foreach item in comboBoxList { iMaxLen = (item.Length > iMaxLen) ? item.Length : iMaxLen; } comboBoxList.DropDownWidth = iMaxLen; Thanks.

  • Is defragging tough on replication?

    - by Jim
    I've been told that defragging causes the log to grow tremendously. Is this true? If so, is there something better to do than defragging that will not impact the log as much? We are running SQL Server 2005 replicating between 2 sites.

  • Converting String^ and Collection of String^ to const char*

    - by Jim Jones
    Using VS2008 Managed C++ to wrap a dll. The native method takes a series of single const char* values and a collection of char* values. Going to make an example function: Function1(char * value1, TF_StringList& catList); TF_StringList is a dll class with 3 insert methods, the one I want to use is: TF_StringList::insert(const char* str); So I set up a wrapper method of: WrapperClass::callFunction(String^ mvalue1, ArrayList mcatList); mvalue1 is converted to const char* using: const char* value1 = (char*)(Marshal::StringToHGlobalAnsi(mvalue1)).ToPointer(); However, when a get to the collection of strings, I iterate over it getting each string using the index: String^ mstr = mcatList[i]; Have tried every way of converting String^ to const char* and in every case the TF_StringList::insert(const char* str) method throws a C2663 error which has to do with the const-ness of the value. What is the problem?

  • Need to work out database structure

    - by jim smith
    Hi, Just need a little kickstart with this. I have Mysql/PHP, and I have 5,000 products. I have 30 companies I need to store some data for those 30 companies for each product as follows: a) prices b) stock qty I also need to store data historically on a daily basis. So the table... It makes sense that the records will be the products because there's 5000, and if I put the companies as the columns, I can store the prices, but what about the stock quantities? I could create two columns for each compoany, one for prices, one for qty. Then make the tablename the date for that day...so theer would be a new table for every day with 5000 products in it? is this the correct way? Some idea on how I'll be retreiving data the top 5 lowest prices (and the company) by product for a certain date the price and stock changes in the past 7 days by product

  • NSWindowController and isWindowLoaded

    - by Jim
    Hi, I have an NSWindowController and I initialize it like this; + (MyWindowController *) sharedController { static MyWindowController *singleton = nil; if (!singleton) singleton = [[self alloc] initWithWindowNibName: @"myWindow"]; return singleton; } and I show windows like this; [[MyWindowController sharedController] showWindow: nil]; Now the problem is that I need information from some controls on that window. But I do not want to load the window if it's not yet loaded because then I can just go with the defaults. Should I use @property to access the singleton? or what is recommended here? (If @property, then please give me the readonly, nonatomic attributes too.)
