• C# RichTextBox - Partially setting DetectUrls=false

  - by Suds

  Hi, I have this RichTextBox and I have embedded some http links in it. I have set DetectUrls = true, and it displays the links correctly and handles in the event. In the same RichTextBox, I have one more string displayed which looks like this Type http://< Your host name Now, since DetectUrls= true, the portion "http://<" is displayed as a link, while I want this to be text. If I set the DetectUrls=false just before displaying this string, none of the other links are displayed as links. Is there a way to partially set DetectUrls for some strings and not for others? Thanks

• generating an objectForKey from an array

  - by Brian

  I'm having success when I use this code to get a string from an array of file names called "fileList": cell.timeBeganLabel.text = [[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]; so I expected the same code to generate the same string as a key for me in this: NSDictionary *stats = [thisRecordingsStats objectForKey:[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; cell.durationLabel.text = [stats objectForKey:@"duration"]; or this: NSDictionary *stats = [thisRecordingsStats objectForKey:@"%@",[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; Both build without error, and the log shows my data is there: but I'm getting a blank UILabel. Have I not written the dynamic key generator correctly?

• Force to call virtual base function instead of the overriden one.

  - by Roberto Sebestyen

  In the following example "Test that v1 function was called" fails. Is there a way to force call the base implementation of "RunFunction" through an instance of "class V2" ?? class V1 { public virtual string RunFunction() { return "V1"; } } class V2 : V1 { public override string RunFunction() { return "V2"; } } [Test] public void TestCall() { var v1 = (V1)new V2(); var v2 = new V2(); Assert.IsTrue(v1.RunFunction() == "V1", "Test that v1 function was called"); Assert.IsTrue(v2.RunFunction() == "V2", "Test that v2 function was called"); }

• Picking encryption cipher for mcrypt

  - by Autolycus

  I have few questions about this code: <?php $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $key = "This is a very secret key"; $text = file_get_contents('path/to/your/file'); echo strlen($text) . "\n"; $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $text, MCRYPT_MODE_ECB, $iv); file_put_contents('path/to/your/file', $crypttext); ?> It encrypts the file just fine, however it adds additional nulls at the end, so if I encrypt: a test string is this one and here is a new line once decrypted becomes: a test string is this one and here is a new line 000000000000000 What's going on? Second, is MCRYPT_RIJNDAEL_256 compatible with AES-128? Finally, how would I let another party decrypt a file I've encrypted? They would need to know which encryption was used and I am not sure what to tell them.

• download html source android?

  - by mars

  I'm trying to download a website source code and display it in a textbox but I seem to get an error and can't figure it out :s public void getHtml() throws ClientProtocolException, IOException { HttpClient httpClient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); HttpGet httpGet = new HttpGet("http://www.spartanjava.com"); HttpResponse response = httpClient.execute(httpGet, localContext); String result = ""; BufferedReader reader = new BufferedReader( new InputStreamReader( response.getEntity().getContent() ) ); String line = null; while ((line = reader.readLine()) != null){ result += line + "\n"; Toast.makeText(activity.this, line.toString(), Toast.LENGTH_LONG).show(); } } how come this doesn't work and throw an IOException?

• How do I "valueOf" an enum given a class name?

  - by stevemac

  Lets say I have a simple Enum called Animal defined as: public enum Animal { CAT, DOG } and I have a method like: private static Object valueOf(String value, Class<?> classType) { if (classType == String.class) { return value; } if (classType == Integer.class) { return Integer.parseInt(value); } if (classType == Long.class) { return Long.parseLong(value); } if (classType == Boolean.class) { return Boolean.parseBoolean(value); } // Enum resolution here } What can I put inside this method to return an instance of my enum where the value is of the classType? I have looked at trying: if (classType == Enum.class) { return Enum.valueOf((Class<Enum>)classType, value); } But that doesn't work.

• Excel Interop: Fastest way to change color of portions of text in a huge range of cells

  - by Kyopaxa

  There some articles about the fastest way to write data using Excel interop assigning directly an Array of data to the value of the range. Like: string[,] multidimensionalArrayData = new string[200, 3]; // (...) Fill multidimensionalArrayData with your data dataSheet.Range["A1:C200"].Value = multidimensionalArrayData; There are also some articles about how to change the Font color of a specific portion of text, for example (VB this time): With ActiveCell.Characters(Start:=3, Length:=3).Font .Name = "Arial" .FontStyle = "Regular" .Size = 10 .Color = "Red" .ThemeFont = xlThemeFontNone End With The question now is, what would be the fastest way to change the color of specific portions of text for thousands of cells? Currently, in my C# code, I have to do it cell by cell, with a horrible performance hit. Is there a way to fill an array of 'Characters' objects in C# and pass that array to a range in one go? Any other solutions?

• XML/XSL nub: Is it possible to create an COMPOSITE XML/XSLT document?

  - by jmweekes

  I have just recently (like 2 days) started using XSLT documents with XML. I understand the basics and am able to generate a formatted document using an .XML document that references a separate .XSLT document. My question, as in the subject, is "Is it possible to create a SINGLE, composite document that contains both the XML data and XSLT processing/formatting/styling and displays as formatted HTML?" I am writing a desktop application in which I need to generate a formatted document on the fly from XML stored in the database. I want to do this without creating or referencing any actual physical files. I will generate a text string containing the XML/XSLT document and feed this to a WebBrowser component for formatted display. Hopefully what I want to do doesn't totally go against the whole XML/XSLT methodology. Any information, direction or suggestions will be greatly appreciated.

• C# how to sort a list without implementing IComparable manually?

  - by JL

  I have a fairly complex scenario and I need to ensure items I have in a list are sorted. Firstly the items in the list are based on a struct that contains a sub struct. For example: public struct topLevelItem { public custStruct subLevelItem; } public struct custStruct { public string DeliveryTime; } Now I have a list comprised of topLevelItems for example: var items = new List<topLevelItem>(); I need a way to sort on the DeliveryTime ASC. What also adds to the complexity is that the DeliveryTime field is a string. Since these structs are part of a reusable API, I can't modify that field to a DateTime, neither can I implement IComparable in the topLevelItem class. Any ideas how this can be done? Thank you

• Convert "minutes since midnight" to time (convert to NSDate?)

  - by Canada Dev

  I am getting some open/closed times as integers since midnight. For example: "1140" = 19:00 (or 7 pm if you will) or; "570" = 9:30 (or 9.30 am) I can easily get the time in European format, just by doing doing a simple calculation and formatting: [NSString stringWithFormat:@"%d:00", (T / 60)] However, this doesn't work for half hours, such as "570 minutes since midnight". Also, I run into problems if I want to include a bit of localization, because some people may prefer AM/PM times. Does NSDate include a method for easily implementing times using the above? Or can anyone tell me how I would at least convert a time like "570 minutes since midnight" to 9:30 properly. Right now it obviously won't write the :30 part. Thank you

• How to find out how namespace got polluted?

  - by dehmann

  Consider the following little piece of code: // all of these include other headers, lots of code: #include "myheader1.h" #include "myheader2.h" #include <string> void foo() { string s("hello world"); // oh no, why does this compile?? } This compiles, so obviously some of the recursively included header files has a using namespace std; somewhere. How would you go about finding out where that offending line of code is? Just using grep on all header files won't really work because that statement is often used inside a function, where it is safe and won't pollute the rest of the code.

• When open-sourcing a live Rails app, is it dangerous to leave the session key secret in source contr

  - by rspeicher

  I've got a Rails app that's been running live for some time, and I'm planning to open source it in the near future. I'm wondering how dangerous it is to leave the session key store secret in source control while the app is live. If it's dangerous, how do people usually handle this problem? I'd guess that it's easiest to just move the string to a text file that's ignored by the SCM, and read it in later. Just for clarity, I'm talking about this: # Your secret key for verifying cookie session data integrity. # If you change this key, all old sessions will become invalid! # Make sure the secret is at least 30 characters and all random, # no regular words or you'll be exposed to dictionary attacks. ActionController::Base.session = { :key => '_application_session', :secret => '(long, unique string)' } And while we're on the subject, is there anything else in a default Rails app that should be protected when open sourcing a live app?

• In .NET, how can I convert from "0.000" to a 'long'?

  - by willem

  I have a string, "0.000" (or any similar string), that I would like to convert to a long. I am happy to "chop-off" anything after the decimal. What is the best way to go about this? I can convert to double and then to long, but I'm just wondering if there is an easier way. All the following statements throw exceptions: long l3 = Convert.ToInt64(nrToConvert); long l1; long.TryParse(nrToConvert, out l1); long l2 = long.Parse(nrToConvert);

• Standardize word macro usage within the team

  - by user138010

  Hi, I have a team of 10 persons who work on word documents, they format them as per our defined guidlines. To complete the work fast we have created a macro that has been updated on all the machines. This macro corrects the font, size and formatting. How can I ensure and implement that nobody can change/replace or delete this macro from their system? In case this happens I should get an alert. Can something be done at the system or programme level? Thanks, PK

• grep --include command doesn't work in OSX zsh

This is my command grep --include=*.rb -rnw . -e "pattern" Zsh tells me that zsh: no matches found: --include=*.rb It seems that grep doesn't support --include option.

• Why does `Array(0,1,2) == Array(0,1,2)` not return the expected result?

  - by soc

  As far as I understand, Scala's == defines the natural equality of two objects. I expected that Array(0,1,2) == Array(0,1,2) compares the natural equality e. g. checks if all elements of the array return true when compared with the corresponding elements of the other array. People told me that Scala's Array is just a Java [] which only compares identity. But Scala's String is also just a Java String but Scala overrides equals to compare natural equality. I wonder why Array's equals method was not overridden, too. Thank you for your thoughts!
