• crazy asp.net error

  - by dominic

  Hi I am having a problem debugging an issue on a website. Everything works locally, the local and server databases are the same The strange thing about the error is that it points to my local dev machine in the error stack. Is that crazy or what, The files are published and being hosted on a server machine and the error is pointing to a line of code on my local dev box. I feel like I am losing the plot. Can someone pls help be clear the air here because this is very weird Error in '/' Application. Index was out of range. Must be non-negative and less than the size of the collection.

• Oracle - Is there any effects of not having a primary key on a table ?

  - by Sathya

  We use sequence numbers for primary keys on the tables. There are some tables where we dont really use the primary key for any querying purpose. But, we have Indexes on other columns. These are non-unique indexes. The queries use these non-primary key columns in the WHERE conditions. So, I dont really see any benefit of having a primary key on such tables. My experience with SQL 2000 was that, it used to replicate tables which had some primary key. Otherwise it would not. I am using Oracle 10gR2. I would like to know if there are any such side-effects of having tables that dont have primary key.

• Does margin-left:2px; render faster than margin:0 0 0 2px;?

  - by Christopher Altman

  Douglas Crockford describes the consequence of Javascript inquiring a node's style. How simply asking for the margin of a div causes the browser to 'reflow' the div in the browser's rendering engine four times. So that made me wonder, during the initial rendering of a page (or in Crockford's jargon a "web scroll") is it faster to write CSS that defines only the non-zero/non-default values? To provide an example: div{ margin-left:2px; } Than div{ margin:0 0 0 2px; } I know consequence of this 'savings' is insignificant, but I think it is still important to understand how the technologies are implemented. Also, this is not a question about formatting CSS--this is a question about the implementations of browsers rendering CSS. Reference: http://developer.yahoo.com/yui/theater/video.php?v=crockonjs-4

• Suppressing the language select button iPhone

  - by AWinter

  I'm working on an application now that contains an account register section. One field with secureTextEntry = NO (for registering only). The idea is this make registration faster and hopefully increases the number of signups. It's simple enough for me to just place a regular UITextField but if the user has any additional language keyboards then it's possible for the user to enter non-password friendly characters. Unlike in when secureTextEntry = YES. I know I can do textField.keyboardType = UIKeyboardTypeASCIICapable to get the text field to display the ASCII keyboard first, but the user will still have the keyboard switch button which will allow them to get to undesirable characters. Is there a simple method for suppressing the international button or forcing ASCII only keyboard with no international button? [EDIT] Another perhaps better option might be to suppress multi byte keyboards or even to display the text in the case that secureTextEntry = YES any ideas here? [EDIT AGAIN] I've decided it's a really bad idea to suppress the international button as non-multibyte characters should all be allowed.

• Linux standard input issue

  - by George2

  Hello everyone, I am new to Linux. And I am using Red Hat Enterprise Version 5. There is a ruby program which use standard input as its input (e.g. the Ruby program process input from standard input). I think standard input should be keyboard, correct? So, I think other kinds of input (non-standard input) should not work (i.e. the ruby program should not be able to read input from such non-standard input), but actually I have tried using pipe works, I am so confused because I think pipe should be some other kinds of input -- other than standard input, why it could work? i.e. put text "123" in abc.txt with pipe, could achieve the same result as using keyboard as input to type "123" for the ruby program. Here is the sample which works and makes me confused, cat abc.txt | ~/test/rubysrc/foo.rb thanks in advance, George

• How can I clip strings in Java2D and add ... in the end?

  - by Jonas

  I'm trying to print Invoices in a Java Swing applications. I do that by extending Printable and implement the method public int print(Graphics g, PageFormat pf, int page). I would like to draw strings in columns, and when the string is to long I want to clip it and let it end with "...". How can I measure the string and clip it at the right position? Some of my code: Font headline = new Font("Times New Roman", Font.BOLD, 14); g2d.setFont(headline); FontMetrics metrics = g2d.getFontMetrics(headline); g2d.drawString(myString, 0, 20); I.e How can I limit myString to be max 120px? I could use metrics.stringWidth(myString), but I don't get the position where I have to clip the string. Expected results could be: A longer string that exc... A shorter string. Another long string, but OK

• Should I use Perl or PHP or something else for this project?

  - by Clinton

  I'm about to embark on a project that will need to: Process XML Heavy text parsing of non-xml documents Insertion of data from xml and non-xml documents into a relational DB. Present processed data to user from db using webpages. The website will be subject to short periods of very heavy loads to pages (300+ visitors a minute for several minutes), but most of the time will be idle (a dozen or so visitors a minute). The ability to cache or scale to load will be very nice. I have a very strong background in Java and web services, but I do not want to use Java for this project as I'd like to diversify my skill set. Which language would you recommend and what are some pros and cons that you might recognize from your own experiences?

• Sanitize a string from ascii art

  - by Toto

  I need to sanitize article titles when (creative) users try to "attract attention" with some bad "ascii art". Exemples: Buy my product !!!!!!!!!!!!!!!!!!!!!!!! Buy my product !? !? !? !? !? !? Buy my product !!!!!!!!!.......!!!!!!!! Buy my product <----------- Some acceptable solution would be to reduce the repetition of non-alphanum to 2. So I would get: Buy my product !! Buy my product !? !? Buy my product !!..!! Buy my product <-- This solution did not work that well: preg_replace('/(\W{2,})(?=\1+)/', '', $title) Any idea how to do it in PHP with regex? Other better solution is also welcomed (I cannot strip all the non-alphanum characters as they can make sense).

• What's the proper technical term for "high ascii" characters?

  - by moodforaday

  What is the technically correct way of referring to "high ascii" or "extended ascii" characters? I don't just mean the range of 128-255, but any character beyond the 0-127 scope. Often they're called diacritics, accented letters, sometimes casually referred to as "national" or non-English characters, but these names are either imprecise or they cover only a subset of the possible characters. What correct, precise term that will programmers immediately recognize? And what would be the best English term to use when speaking to a non-technical audience?

• SQL Server 2008 BULK INSERT causes more reads than writes. Why?

  I've huge a table (a few billion rows) with a clustered index and two non-clustered indices. A BULK INSERT operation produces 112000 reads and only 383 writes (duration 19948ms).

• jQuery Validation Engine with Mime

  - by Diego Pucci

  I have this custom rule with tje jQuery validation Engine: "validateMIME": { "func": function(field, rules, i, options){ var fileInput = field[0].files[0]; var MimeFilter = new RegExp(rules[3],'i'); if (fileInput) { return MimeFilter.test(fileInput.type); } else { return true;} }, "alertText": "* Estensione non supportata" }, The problem is that this is working ONLY if the field is required. But in my case the field is not required, but if filled then the Mime type needs to be checked. How do I edit this function to work with non required fields? what's wrong with it? Thanks

• NSFormatter problem: not getting called for the empty string

  - by Enchilada

  I have created a custom formatter for my (read-only) table column. It looks like this: - (NSString *)stringForObjectValue:(id)anObject { NSAssert([anObject isKindOfClass:[NSString class]] && anObject != nil, @"invalid object"); if ([anObject isEqualToString:@""]) return @"EMPTY"; else return [anObject stringByAppendingString:@"++"]; } Very simple. The corresponding objects are just strings, so it's an string-to-string formatter. All non-empty string objects are returned with @"++" appended to them. Empty string objects should be turned into the @"EMPTY" string. The @"++" gets appended to non-empty strings just fine. The problem is, @"EMPTY" never gets shown! My formatter is never called by Cocoa when the underlying object is the empty string. The corresponding row just keeps being empty, instead of showing my requested @"EMPTY". Any ideas?

• What Web design tool would make a good CityDesk replacement?

  - by Joshua Fox

  I am looking for a tool for building static template-based web sites, your typical brochure-ware for a non-profit or a personal site. I have used CityDesk, but that is out-of-date, unsupported, and has certain problems. Of course there are lots of tools out there, but I cannot find anything similar to CityDesk: WYSIWYG as well as HTML coding a templating system not overdesigned like, say, Dreamweaver built for developers who understand HTML/JS/CSS but easier to use than hand-coding of PHP, Ruby, or other templates in a text editor supporting the editing of pages by non-developers preferably free I'd also like it to be CSS-aware; and to have lots of free templates available. Or alternatively, static template-based sites are often developed nowadays on the Web using a CMS like Django; is that the way to go? Edit: Namo, DreamWeaver, NetObjects Fusion, Coffee Cup, Evrsoft First Page, and Microsoft Expression might be candidates. I'll appreciate comments on these based on the criteria above.

• NSStrings, C strings, pathnames and encodings in iPhone

  - by iter

  I am using libxml2 in my iPhone app. I have an NSString that holds the pathname to an XML file. The pathname may include non-ASCII characters. I want to get a C string representation of the NSString for to pass to xmlReadFile(). It appears that cStringUsingEncoding gives me the representation I seek. I am not clear on which encoding to use. I wonder if there is a "default" encoding in iPhone OS that I can use here and ensure that I can roundtrip non-ASCII pathnames.

• UAC on Win2k8/VIsta x64 - local "Administrator" works but domain account in Administrators group fai

  - by deltanine

  I have come across a strange problem in one of our applications on win2k8/Vista x64 with UAC enabled. It is a process which hosts the UI for our service and runs in the context of the logged on user. When logged in as a domain user who is a member of the "Administrators" group, writing to the registry under HKLM fails due to UAC with access denied. But when logged in as the local "Administrator" account (non-domain) then writing to the registry succeeds. Both accounts are adminstrators - is there a distinction between domain and non-domain accounts with UAC? What gives?

• What does it mean when git pull causes a conflict but git pull --rebase doesn't?

  - by Jason Baker

  I'm pulling from a repository that only I have access to. As far as I know, I've only pushed to it from one repository. A couple of times, I've pulled from it and gotten this: To [email protected]:tsched_dev.git ! [rejected] master -> master (non-fast-forward) error: failed to push some refs to '[email protected]:tsched_dev.git' To prevent you from losing history, non-fast-forward updates were rejected Merge the remote changes before pushing again. See the 'Note about fast-forwards' section of 'git push --help' for details. Generally, that just means that I have to do a git pull (although all the changes should be fast-forwardable). When I do a git pull, I get conflicts. If I do a git pull --rebase, it works fine. What am I doing wrong?

• how best to set text alignment in a table

  - by ericslaw

  Does anyone know of a jquery plugin or snippet that will auto-text-align cells in a table based on content? Specifically, all table cells would be right justified unless there is a visible non-number related character in the cell, then it would be left justified. I'd like to use something like this regular expression to identify non-number related characters in a cell: /[^0-9% +-()]/ Is there a real simple way to accomplish this? I would think something like this: $("td:contains('[^0-9% +-()]')").addClass("left"); would do the trick, but I don't think 'contains' can take a regular expression.

• Get positions for NAs only in the "middle" of a matrix column

  - by Abiel

  I want to obtain an index that refers to the positions of NA values in a matrix where the index is true if a given cell is NA and there is at least one non-NA value before and after it in the column. For example, given the following matrix [,1] [,2] [,3] [,4] [1,] NA 1 NA 1 [2,] 1 NA NA 2 [3,] NA 2 NA 3 the only value of the index that comes back TRUE should be [2,2]. Is there a compact expression for what I want to do? If I had to I could loop through columns and use something like min(which(!is.na(x[,i]))) to find the first non-NA value in each column, and then set all values before that to FALSE (and the same for all values after the max). This way I would not select leading and trailing NA values. But this seems a bit messy, so I'm wondering if there is a cleaner expression that does this without loops.

• Can Tomcat provide seperate (or HTTPS only) sessions for HTTPS requests?

  - by Joe

  I have a web application which contains both secure (SSL) and non-secure pages. A user can login to the site and must appear logged-in in both the SSL and non-SSL areas. (NB. SSL isn't implemented via Tomcat, but via Apache HTTPD servers which sit in front of Tomcat - so Tomcat has no SSL configuration.) The logged-in state is currently maintained via a servlet session (using Tomcat's vanilla session management). The obvious issue with this approach is that the JSESSIONID cookie is transported over both HTTP and HTTPS connections, meaning that it's potentially possible to intercept it and hijack the session. Are there any solutions to this without rolling our own session management (i.e. does Tomcat cater for this situation)? I'm prepared to implement our own session management, but don't want to reinvent something that may already be supported.
