• Looking for a free tool to visualize object relationships for C#

  - by vfilby

  Here is my ideal solution: a free tool that reads a .csporj or .sln and generates a pretty picture that shows all the objects and how they are related. By relationships, I don't mean inheritance but rather dependency. For example, if we have a Car object and Car has a member variable Wheel, I would like that Car depends on Wheel to be visualized in the graph. I know visual studio can do inheritance graphs, but that is only half of what I am looking for. Is what I am looking for possible? Are there any tools that do something similar?

• How do chains work in Rainbow tables?

  - by James Moore

  Hello, I was wondering if should one could explain in detail how chains work in rainbow tables as though you would a complete novice but with relevance to programming. I understand that a chain is 16 bytes long. 8 bytes mark the starting point and 8 mark the end. I also understand that in the filename we have the chain length i.e. 2400. Which means that between our starting point and end point in just 16 bytes we have 2400 possible clear texts? What? How does that work? in those 16 bytes how do i get my 2400 hashes and clear texts or am i miss understanding this? Your help is greatly appreciated. Thanks P.s. I have read the related papers and googled this topic a fair bit. I think im just missing something important to make these gears turn.

• Storing DOM reference elements in a Javascript array

  - by webzide

  Dear experts, I was trying to dynamically generate DOM elements using JS. I read from Douglas Crockford's book that DOM is very very poorly structured. Anyways, I would like to create a number of DIVISION elements and store the reference into an array so it could be accessed later. Here's the code for(i=0;i<3;i++){ var div=document.body.appendChild(document.createElement("div")); var arr=new Array(); arr.push(div); } Somehow this would not work..... There is only 1 div element created. When I use the arr.length to test the code there is only 1 element in the array. Is there another way to accomplish this? Thanks in advance

• Jquery Autocomplete Unable to Empty Input on Internet Explorer

  - by Matias

  Hi, I´ve got a Jquery autocomplete input like the following: $("#cities").autocomplete(regionIDs, { minChars: 2, width: 310, autoFill: true, matchContains: "word", formatItem: function(row) { return row.city + ", " + "<span>" + row.country + "</span>"; }, formatMatch: function(row) { return row.city; }, formatResult: function(row) { return row.city + ", " + row.country; } }); A listener for the input $("#cities").result(function(event, data, formatted) { selectedCity = (data.regionID); }); And the input: <input type="text" class="textbox" id="cities" name="q" autocomplete="off"> The trouble is when I reload the page, Internet explorer displays last user Input in the text box. However, the variable has no value. I have tried with .reset() but no success. Any ideas why ?

• Write wave files to memory in Java

  - by Cliff

  I'm trying to figure out why my servlet code creates wave files with improper headers. I use: AudioSystem.write( new AudioInputStream( new ByteArrayInputStream(memoryBytes), new AudioFormat(22000, 16, 1, true,false), memoryBytes.length ), AudioFileFormat.Type.WAVE, servletOutputStream ); taking a byte array from memory containing raw PCM samples and a servlet output stream that gets returned to the client. In the result I get a normal wave file but with zeros in the chunk size fields. Is the API broken? I would think that the size could be filled in using the size passed in the audio input stream. But now, after typing this out I'm thinking its not making this info available to the outer write() method on AudioSystem. It seems like the AudioSystem.write call needs a size parameter unless it is able to pull the size from the stream... which wouldn't work with an arbitrary sized stream. Does anyone know how to make this example work?

• How do I respond to a specific sequence of key presses?

  - by Sergio Tapia

  The end result is very simple, I have to have something happen when a user types in the letter "n" "o" "t" "e" in that order. 'Note' is the word. I'm making a little application for a friend that will help him take notes, and I want my application to become visible when he types in "note" from anywhere on the machine. Here's what I've got so far: if (e.KeyCode == neededLetter as Keys) { neededLetter = "o"; } I initialize the neededLetter variable with "N" but I'm stuck there. Any help?

• AS3: Showing bufferlength of NetStream

  - by Tinelise

  I am trying to show the buffered amount of a video that is playing. I am using netstream.bufferLength to do this and it kinda seems to be right. Exept from the fact that it is almost constantly the same amount that is buffered. This can't be right? I want it to be like youtube where you can press pause and the buffer will continue to rise. When I click pause it just stays the same.. Anybody knows how to show buffer length?

• Python nested function scopes

  - by Thomas O

  I have code like this: def write_postcodes(self): """Write postcodes database. Write data to file pointer. Data is ordered. Initially index pages are written, grouping postcodes by the first three characters, allowing for faster searching.""" status("POSTCODE", "Preparing to sort...", 0, 1) # This function returns the key of x whilst updating the displayed # status of the sort. ctr = 0 def keyfunc(x): ctr += 1 status("POSTCODE", "Sorting postcodes", ctr, len(self.postcodes)) return x sort_res = self.postcodes[:] sort_res.sort(key=keyfunc) But ctr responds with a NameError: Traceback (most recent call last): File "PostcodeWriter.py", line 53, in <module> w.write_postcodes() File "PostcodeWriter.py", line 47, in write_postcodes sort_res.sort(key=keyfunc) File "PostcodeWriter.py", line 43, in keyfunc ctr += 1 UnboundLocalError: local variable 'ctr' referenced before assignment How can I fix this? I thought nester scopes would have allowed me to do this. I've tried with 'global', but it still doesn't work.

  What is the best way to perform a string manipulation. I wish to perform a substring on a email address to extract the domain detail and populate this to a variable. a java transformer is a possibilty, but i was hoping if i could use a message enricher with a expression to perform this operation. pardon me but i am still a greenhorn on Mule. here is the excerpt from my mule flow which is failing with error cannot resolve method string length. <enricher target="#[flowVars['FromAddressDomain']]" doc:name="Message Enricher"> <expression-transformer expression="#[ payload.fromAddr.substring(payload.fromAddr.lastIndexOf('@')+ 1,payload.fromAddr.lenth())]" doc:name="Expression"></expression-transformer> </enricher>

• Validating a single radio button is not working in available javascript validation script

• Unreachable code detected by using const variables

  - by Anton Roth

  I have following code: private const FlyCapture2Managed.PixelFormat f7PF = FlyCapture2Managed.PixelFormat.PixelFormatMono16; public PGRCamera(ExamForm input, bool red, int flags, int drawWidth, int drawHeight) { if (f7PF == FlyCapture2Managed.PixelFormat.PixelFormatMono8) { bpp = 8; // unreachable warning } else if (f7PF == FlyCapture2Managed.PixelFormat.PixelFormatMono16){ bpp = 16; } else { MessageBox.Show("Camera misconfigured"); // unreachable warning } } I understand that this code is unreachable, but I don't want that message to appear, since it's a configuration on compilation which just needs a change in the constant to test different settings, and the bits per pixel (bpp) change depending on the pixel format. Is there a good way to have just one variable being constant, deriving the other from it, but not resulting in an unreachable code warning? Note that I need both values, on start of the camera it needs to be configured to the proper Pixel Format, and my image understanding code needs to know how many bits the image is in. So, is there a good workaround, or do I just live with this warning?

• Check if hydrated doctrine result is NULL

  - by iggnition

  Hi, I'm trying to check if a result in my DQL is NULL. I got the following DQL query: $q = self::createQuery("l") ->select('i.*, s.aantal, m.naam, c.cat_naam, a.app_id') ->from('InstalledBase i, i.Spare s, i.Apparaat a, a.Categorie c, a.Merk m') ->execute(); return $q; Now i want to check if the s.aantal is NULL so i do: if(is_null($installedbase->Spare->spare_id)) when the variable is NOT null everything works, but when it is actually NULL i get a E notice message: Notice: Trying to get property of non-object in \installedbase\templates\_index.php on line 29 It does see that it is null though because the if condition is executed. Weird thing is i'm doing the exact same thing on another page where it works no problem. But i must be doing something wrong or stupid since those messages generally don't show for nothing. So can anybody explain this to me? :)

• Is my form password being passed in clear text?

  This is what my browser sent, when logging into some site: POST http://www.some.site/login.php HTTP/1.0 User-Agent: Opera/8.26 (X2000; Linux i686; Z; en) Host: www.some.site Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1 Accept-Language: en-US,en;q=0.9 Accept-Charset: iso-8859-1, utf-8, utf-16, *;q=0.1 Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0 Referer: http://www.some.site/ Proxy-Connection: close Content-Length: 123 Content-Type: application/x-www-form-urlencoded lots_of_stuff=here&e2ad811=my_login_name&e327696=my_password&lots_of_stuff=here Can I state that anyone can sniff my login name and password for that site? Maybe just on my LAN? If so (even only on LAN ) then I'm shocked. I thought using <input type="password"> did something more than make all characters look like ' * ' p.s. If it matters I played with netcat (on linux) and made connection browser <= netcat (loged here) <= proxy <= remote_site

• ASP.net VB Timers

  - by Tom Gullen

  I would like to be able to time a page load time in ASP.net (VBscript). Adding Trace="true" to the page directive is nice, but I need to actually time an event and store it in a variable. In ASP it was easy with the Timer object, but in .net I can't find anything on Google. I need something along the lines of: Dim startTime Dim endTime startTime = now() doBigFunction() endTime = now() response.write("That took " & endTime - startTime & " milliseconds") Cheers!

• Conky graph frozen in time

  - by dijxtra

  Is it possible to plot a graph in conky? Give a function a set of values 0-100 and conky plots a graph similar to execgraph? What I want is to visualize how a variable changed in last week. For example, I'd like to make a graph of gold prices in last 14 days. One way I could do that is use "execigraph 86400 python fetch_price_of_gold.py" and keep my box up 24/7 and eventually I'd get a nice graph. But, unfortunately my box isn't up 24/7. Not to mention I'd have to wait 14 days after every reboot ;-) So, any other ideas? :-)

• [jquery/javascript] Trigger function when mouse click inside textarea AND type stop typing...

  - by marc

  Welcome, In short, my website use BBcode system, and i want allow users to preview message without posting it. I'm using JQuery library. I need 3 actions. 1) When user click in textarea i want display DIV what will contain preview, i want animate opening. 2) When user typing, i want dynamical load parsed by PHP code to DIV.

• Simple reduction (NP completeness)

  - by Allen

  hey guys I'm looking for a means to prove that the bicriteria shortest path problem is np complete. That is, given a graph with lengths and weights, I need to know if a there exists a path in the graph from s to t with total length <= L and weight <= W. I know that i must take an NP complete problem and reduce it to this one. We have at our disposal the following problems to choose from: 3-SAT, independent set, vertex cover, hamiltonian cycle, and 3-dimensional matching. Any ideas on which may be viable? thanks

• Need help using the Windows IP Helper API & ParseNetworString in C#.

  - by JohnnyNoir

  I'm attempting to rewrite some C# web service code that uses the Windows IP Helper API call "SendARP" to retreive a remote system's MAC address. SendARP works great - until you cross a network segment as Arp requests aren't routed. I've been looking at the "ParseNetworkString" documentation after happening across its existance on StackOverflow. The quick & dirty algorithm I have in mind is: public static string GetMacAddress(string strHostOrIP) { if (strHostOrIP is IPAddress) { parse results of nbstat -A strHostOrIP return macAddress } if (strHostOrIP is Hostname) { IPHostEntry hostEntry = null; try { hostEntry = Dns.GetHostEntry(strHostOrIP); } catch { return null; } if (hostEntry.AddressList.Length == 0) { return null; } foreach (IPAddress ip in hostEntry.AddressList) { if (ip.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork) { ipAddress = ip; break; } } } return GetMACAddress(ipAddress); } "ParseNetworkString" is new with Vista/Win2008 so I haven't been able to find example C# code demonstrating its use and I'm no C++ coder so if anyone can point me in the right direction...

• How do I create a MessageBox in C# ?

  - by Nick Stinemates

  I have just installed C# for the first time, and at first glance it appears to be very similar to VB6. I decided to start off by trying to make a 'Hello, World!' UI Edition. I started in the Form Designer and made a button named "Click Me!" proceeded to double-click it and typed in MessageBox("Hello, World!"); I received the following error: MessageBox is a 'type' but used as a 'variable' Fair enough, it seems in C# MessageBox is an Object. I tried the following MessageBox a = new MessageBox("Hello, World!"); I received the following error: MessageBox does not contain a constructor that takes '1' arguments Now I am stumped. Please help.

• String labels on boxplot outliers

  - by Benoît Collette

  Hi! I want to put string labels on outliers in a boxplot. Here's a simplification of the dataset I'm using: [,x] [,y] [,z] 7 2 a 10 2 b 112 3 c boxdata<-boxplot(x ~ y) To put values as label on outliers by group, I use this function: for(i in 1:length(boxdata$group)){ text(boxdata$group[i], boxdata$out[i], which(x==boxdata$out[i]),labels=boxdata$out[i],pos=4) } The problem is that I want to put z (string) as label instead of outlier value, but I don't know how to proceed. What do I need to do? Thank you! Ben

• How to stop HTML text in textarea to be interpreted as code

  - by Myone

  I have a textarea that users can edit. After the edit I save the text in a PHP variable $bio. When I want to display it I do this: <?php $bio = nl2br($bio); echo $bio; ?> But if a user for example types an HTML command like "strong" in their text my site will actually output the text as bold. Which is nothing I want. How can I print/echo the $bio on the screen just as text and not as HTML code? Thanks in advance!
