• How to validate parameter values against a data source in Crystal Reports 2008

  - by mjh41

  I have a report designed in Crystal 2008. The report has a parameter field called "Member ID" that I want to use to get a string input from the user running the report. However, I want to do some sort of validation to ensure that the ID they entered is valid (it exists in a database table that I already have set up). Is there any way to do this? I know you can set up dynamic parameters that would give the user a dropdown list of Member ID values to choose from based on the data stored in my database table. But I don't want to make the user sort through thousands of IDs in a dropdown. I just want them to manually enter an ID and then have the report check the entered value against a database table. Is this possible?

• Convert ieee 754 float to hex with c - printf

  - by Michael

  Ideally the following code would take a float in IEEE 754 representation and convert it into hexadecimal void convert() //gets the float input from user and turns it into hexadecimal { float f; printf("Enter float: "); scanf("%f", &f); printf("hex is %x", f); } I'm not too sure what's going wrong. It's converting the number into a hexadecimal number, but a very wrong one. 123.1443 gives 40000000 43.3 gives 60000000 8 gives 0 so it's doing something, I'm just not too sure what. Help would be appreciated

• Compass Rails 3.0 working with 'compass watch' but not without

  - by Mike Blyth

  I'm trying Compass with Rails 3.0.7, just trying to get started. Using gem compass-rails. If I put my sass file in app/assets/stylesheets and run 'compass watch', everything works ok: the compiled css is put into public/stylesheets. However, if I stop 'watch' and rely on Rails to do the compilation, it does not work. Instead, the program looks at the public/stylesheets/sass folder for the input. Furthermore, if a file in that folder has the '@include "compass"' directive, I get an error that the file is not found. How do I force Rails to look in the right place -- app/assets/stylesheets?

• GData for my own API?

  - by Malax

  Hi StackOverflow! Im currently planning to build an API for my service. I want to use GData because it fits the application scheme and there are libraries for many programming languages available. The first question that rose: Am I allowed to do that? I mean, Google put lots of work into the GData specification and have some sort of copyright. Does anyone know anything about this issue or did that before? You could extend the case if you want to specifically mimic an API which uses GData like the YouTube API to have my API 100% compliant. This is not my case, but I was wondering about that too. :-) Thank you for any input, Malax Edit: Note that i want to use it for my own service. So, I am implementing an API using the GData protocol, not using one of the Google APIs.

• newbie question -- how does one override show for a newtype?

  - by gatoatigrado

  I want to override the default integer constructors in Haskell so they produce strings (mostly for curiosity, but temporarily to make a nice input alternative for LaTeX's \frac{}{} inconvenience). I wanted to be able to use the language itself, instead of a special parser, but I guess that's probably not going to work out... module Main where import Prelude hiding ((+)) newtype A = A Int deriving (Eq, Show, Num) default (A) (+) :: A -> (A -> String) (A a) + (A b) = (show a) ++ " + " ++ (show b) main2 = 3+4 main :: IO () main = putStrLn main2 The problem with the above is that the + function only works for (A, A) instead of (A, String), etc. If one simply leaves out the pattern match "(A a)" and writes "a" instead, then the show() function prepends "A " so "3" becomes "A 3" instead of just "3". I want to override Show for A, but it seems to be quite a headache...

• convert ArrayList.toString() back to ArrayList in one call

  - by dotnetnewbie

  I have a toString() representation of an ArrayList. Copying the toString() value to clipboard, I want to copy it back into my IDE editor, and create the ArrayList instance in one line. In fact, what I'm really doing is this: my ArrayList.toString() has data I need to setup a unit test. I want to copy this ArrayList.toString() into my editor to build a test against this edge case I don't want to parse anything by hand My input looks like this: [15.82, 15.870000000000001, 15.92, 16.32, 16.32, 16.32, 16.32, 17.05, 17.05, 17.05, 17.05, 18.29, 18.29, 19.16] The following do not work: Arrays.asList() google collections Lists.newArrayList() Suggestions?

• One position right barrel shift using ALU Operators?

  - by Tomek

  I was wondering if there was an efficient way to perform a shift right on an 8 bit binary value using only ALU Operators (NOT, OR, AND, XOR, ADD, SUB) Example: input: 00110101 output: 10011010 I have been able to implement a shift left by just adding the 8 bit binary value with itself since a shift left is equivalent to multiplying by 2. However, I can't think of a way to do this for shift right. The only method I have come up with so far is to just perform 7 left barrel shifts. Is this the only way?

• wmd editor sanitizing

  - by Ke

  hi, i am trying to find ways to sanitize the input of wmd editor Specifically, I am trying to make HTML tags only available in the <code>tags that wmd generates. Is that possible My problem is that the following code is rendered as html which is vunerable to potential xss attacks e.g. <a onmouseover="alert(1)" href="#">read this!</a> The above code renders normally both in preview mode and when saved to the db. I notice that SO doesnt seem to have this problem. The same code is just rendered as text. I notice that SO has shared their code here http://refactormycode.com/codes/333-sanitize-html Do I really have to use c# in order to sanitize wmd to do this? Any help appreciated , cheers Ke

• Javascript Bookmarklet fails in IE8

  - by songdogtech

  Anyone want to take a stab at why this bookmarklet fails in IE8? It turns all text uppercase in Friefox and Safari. But in IE8, it simply stalls with "loading..." I've enabled scriplets and the security settings in IE8. Update 3/13/10: I've discovered that IE limits the data length of Favorites, so I need to find a work around to prevent IE from truncating the bookmarklet. javascript: (function(){ var i,t,D=document; for(i=0;t=D.getElementsByTagName('textarea')[i];++i) t.value=t.value.toUpperCase(); var newSS,styles='*{text-transform:uppercase}input,textarea{text-transform:none}'; if(D.createStyleSheet){ D.createStyleSheet("javascript:'"+styles+"'"); } else{ newSS=D.createElement('link'); newSS.rel='stylesheet'; newSS.href='data:text/css,'+escape(styles); D.documentElement.childNodes[0].appendChild(newSS); } } )()

• How to get users to read error messages?

  - by FX

  If you program for a nontechnical audience, you find yourself at a high risk that users will not read your carefully worded and enlightening error messages, but just click on the first button available with a shrug of frustration. So, I'm wondering what good practices you can recommend to help users actually read your error message, instead of simply waiving it aside. Ideas I can think of would fall along the lines of: Formatting of course help; maybe a simple, short message, with a "learn more" button that leads to the longer, more detailed error message Have all error messages link to some section of the user guide (somewhat difficult to achieve) Just don't issue error messages, simply refuse to perform the task (a somewhat "Apple" way of handling user input) Edit: the audience I have in mind is a rather broad user base that doesn't use the software too often and is not captive (i.e., not an in-house software or narrow community). A more generic form of this question was asked on slashdot, so you may want to check there for some of the answers.

• Best Practices for Sanitizing SQL inputs Using JavaScript?

  - by Greg Bulmash

  So, with HTML5 giving us local SQL databases on the client side, if you want to write a select or insert, you no longer have the ability to sanitize third party input by saying $buddski = mysql_real_escape_string($tuddski) because the PHP parser and MySQL bridge are far away. It's a whole new world of SQLite where you compose your queries and parse your results with JavaScript. But while you may not have your whole site's database go down, the user who gets his/her database corrupted or wiped due to a malicious injection attack is going to be rather upset. So, what's the best way, in pure JavaScript, to escape/sanitize your inputs so they will not wreak havoc with your user's built-in database? Scriptlets? specifications? Anyone?

• Why is my masm32 program crashing whenever I try using interrupts?

  - by incrediman

  Here's the code: .386 ;target for maximum compatibility .model small,stdcall ;model .code main: int 20h END main Result: http://img705.imageshack.us/img705/3738/resultom.png "test.exe has stopped working" - always right when it reaches the interrupt. This is the interrupt I'm trying to use. It should simply exit the program. Others I've tried include character input/output, etc.. Nothing works. I'm on windows 7, using masm32 with the WinAsm IDE. There are so many cool things it seems I should be able to do with interrupts... however, it crashes whenever I try to use an interrupt - always the same way. This seems related and possibly useful: http://stackoverflow.com/questions/1414260/dos-interrupt-in-masm-x86-assembly-crashing ...but I haven't really been able to figure anything out from it. Any suggestions?

• setUserCredentials from Google data api is stuck

  - by yogsma

  Well, since I am facing some issues with OAuth implementation, I decided to go back to normal method where users will input their login id and password and I will use them in my code to validate their google account to fetch calendar information. So when user enters login id and password, the page is getting stuck. When I check the code, setUserCredentials is the method where it is getting stuck. But when I enter my login id and password and debug on development site, it works fine. There is no problem when I debug. And importantly , the problem appears for first time only, once I debug the code and next time I try it without breakpoint, it works fine. Does anyone know why setUserCredentials takes time or any way I can track why it is taking so time? I have asked the same question on Google data api forum, but nobody answered it.

• asp.net mvc textbox date format

  - by maxxxee

  My form contains a textbox for date input. When submitted the data is used to add a row to the table. The view is strongly typed to the table. The problem is that the database server is configured with US date format. But the users need to use UK date format in the textbox. When users enter uk date format error is thrown. The database server configuration cannot be changed. So what can be done so that users can enter date in uk format?

• Out of Memory - web applications

  Hi all, I am trying to figure out why Jetty 6.1.22 is running out of memory on my laptop. I have 2 web applications running JBoss Seam, Hibernate (with EHCache), and separate Quartz scheduler instances. With little load, the server dies throwing OutOfMemory. What can I look for? Would you think that I am not properly closing handles for input streams or files? I tried profiling my application with Netbeans, but it works off and on. Usually, it ends up locking up even though it doesn't use that much CPU or memory. Walter

• xforms "instance namespace" issue

However, apparently due to a namespace issue none of my Xpath expressions resolve.My form works fine on a simple instance when the instance file has no namespace. However, I need the namespace support. My instance file has a namespace "ai:inventory." I am referencing the instance data Where should I be declaring the prefix "ai" for my namespace so that my XPath expressions can find the appropriate elements? /ai:inventory/products ?

• Building big, immutable objects without using constructors having long parameter lists

  - by Malax

  Hi StackOverflow! I have some big (more than 3 fields) Objects which can and should be immutable. Every time I run into that case i tend to create constructor abominations with long parameter lists. It doesn't feel right, is hard to use and readability suffers. It is even worse if the fields are some sort of collection type like lists. A simple addSibling(S s) would ease the object creation so much but renders the object mutable. What do you guys use in such cases? I'm on Scala and Java, but i think the problem is language agnostic as long as the language is object oriented. Solutions I can think of: "Constructor abominations with long parameter lists" The Builder Pattern Thanks for your input!
