• Why vba doesnt handling Error 2042

  - by Jonathan Raul Tapia Lopez

  I have a variable "fila" with a full line with excel's values; The problem is when in excel I have --#N/A-- vba take that value like "Error 2042" and I cannot asign that value to "valor" and produce me an error, until this point everything is ok, now I am trying to define a "On error goto" for go to the "next" iteration in the loop "for", but I dont know Why vba doesnt handle the error. Do While Not IsEmpty(ActiveCell) txt = ActiveCell.Value2 cell = ActiveCell.Offset(0, 1).Value2 fila = Range("C20:F20") For j = 1 To UBound(fila, 2) On Error GoTo Siguiente If Not IsEmpty(fila(1, j)) Then valor = fila(1, j) cmd = Cells(1, j + 2).Value2 devolver = function1(cmd, txt, cell, valor) arrayDevolver(p) = devolver p = p + 1 End If Siguiente: Next Loop '

• How to disable a warning in Delphi about "return value ... might be undefined"?

  - by Lasse V. Karlsen

  I have a function that gives me the following warning: [DCC Warning] filename.pas(6939): W1035 Return value of function 'function' might be undefined The function, however, is clean, small, and does have a known, expected, return value. The first statement in the function is: Result := ''; and there is no local variable or parameter called Result either. Is there any kind of pragma-like directive I can surround this method with to remove this warning? This is Delphi 2007. Unfortunately, the help system on this Delphi installation is shot, so I can't pop up the help for that warning right now. Anyone know off the top of their head what I can do?

• Ruby w/ Postgres & Sinatra - Query won't order right with parameter??

  - by alleywayjack

  So I set a variable in my main ruby file that's handling all my post and get requests and then use ERB templates to actually show the pages. I pass the database handler itself into the erb templates, and then run a query in the template to get all (for this example) grants. In my main ruby file: grants_main_order = "id_num" get '/grants' do erb :grants, :locals => {:db=>db, :order=>grants_main_order, :message=>params[:message]} end In the erb template: db = locals[:db] getGrants = db.exec("SELECT * FROM grants ORDER BY $1", [locals[:order]]) This produces some very random ordering, however if I replace the $1 with id_num, it works as it should. Is this a typing issue? How can I fix this? Using string replacement with #{locals[:order]} also gives funky results.

• make a lazy var in scala

  - by ayvango

  Scala does not permit to create laze vars, only lazy vals. It make sense. But I've bumped on use case, where I'd like to have similar capability. I need a lazy variable holder. It may be assigned a value that should be calculated by time-consuming algorithm. But it may be later reassigned to another value and I'd like not to call first value calculation at all. Example assuming there is some magic var definition lazy var value : Int = _ val calc1 : () => Int = ... // some calculation val calc2 : () => Int = ... // other calculation value = calc1 value = calc2 val result : Int = value + 1 This piece of code should only call calc2(), not calc1 I have an idea how I can write this container with implicit conversions and and special container class. I'm curios if is there any embedded scala feature that doesn't require me write unnecessary code

• Updating Activity UI from Different Activity Method?

  - by stormin986

  I have a tab widget where one of the tabs is a chat-type feature. I want to update the chat data at an interval (variable depending on whether the chat tab is active or not). The best approach seemed to be using an AsyncTask in my main TabActivity class, as that would avoid any issues of the chat activity being destroyed while in the background, while an AsyncTask was running. I wanted to ensure that the Activity isn't destroyed and recreated, thus causing my AsyncTask to be unable to modify the actual active Activity's data. However, now that my AsyncTask is in the TabActivity activity, I don't have a direct way to call my Chat's ListAdapter notifyDataSetChanged() from my onPostExecute() method anymore. Is there a way to get a reference to a given Tab's current Activity from the TabHost/TabActivity? Or, alternatively, can I assume my chat activity will never be destroyed as a child activity of the TabActivity activity (well, never destroyed while the TabActivity is active at least), and then just put the AsyncTask in the Chat Activity?

• Scrapy + Eclipse PyDev : how to setup the debugger?

  - by AsTeR

  I've successfully setup Eclipse with my Scrapy project. I did it by setting a new Run/Debug configuration : Whose main module links to Scrapy /usr/local/bin/scrapy for me (I've found suggestion to use cmdline.py but that failed on my computer (OSX Lion & scrapy installed through easy_install) Defining the arguments to send "crawl ny" in my case as I would if I used the Scrapy command line Setting the correct working directory (${workspace_loc:My Project/src} in my case) Eclipse can successfully launch my project, but I've no debbuger. I'm missing my breakpoints and variable inspection, does anyone know how to setup the debbugger with this environment ?

• How to extend abstract Entity class in RIA Services

  - by Calanus

  I want to add a bool variable and property to the base Entity class in my RIA services project so that it is available throughout all the entity objects but seem unable to work out how to do this. I know that adding properties to actual entities themselves is easy using .shared.cs and partial classes but adding such properties to the Entity class using similar methods doesn't work. For example, the following code doesn't work namespace System.ServiceModel.DomainServices.Client { public abstract partial class Entity { private bool auditRequired; public bool AuditRequired { get { return auditRequired; } set { auditRequired = value; } } } } All that happens is that the existing Entity class gets totally overriden rather than extending the Entity class. How do I extend the base Entity class so that functionality is available thoughout all derived entity classes?

• $("body").scrollTop() doesn't update in safari

  - by Kristoffer Nolgren

  I'm working on a website: http://beta.projektopia.se/ the body has several background-images that are updated on scroll like this: $(document).ready(function(){ $(document).scroll(function(){ var scrollfactor=$("body").scrollTop()*0.2; var centerscrollpos =scrollfactor+613; var docheight = $(document).height(); var windowheight = $(window).height(); var bottompos = (docheight-980)-((docheight-windowheight)*0.2)+scrollfactor; var scrollpos = 'center '+scrollfactor+'px,center '+bottompos+'px, center '+ centerscrollpos+'px,center 0px'; $("body").css("background-position", scrollpos); }); }); Lots of calculations, but the important thing is that a scrollpos is created that should change the position of the background when you scroll, to create a parallax-effect. It works great in chrome, but in firefox, the variable scrollfactor, that is suppose to get the current scroll-position, doesn't update. ps, some people have this issue due to lack of correct doctype. I believe i have declared it correctly like this: <!DOCTYPE html>

• Stopping the manipulation of variables used for data collection?

  - by Ruinous

  I am working on a project in java and I was hoping to be able to collect statistics from the client and a possible problem that I fear will occur is the manipulation of the variables used for collection which will lead to illegitimate statistics. Is it in any way possible to prevent the manipulation of variables or is it always possible? For example: I want to log the actions made per hour from the client. The variable acting as a counter for the amount of actions performed is manipulated and a much larger amount is added to the counter. This data is then uploaded to the server (Of course using a multi-tier architecture to prevent even more possible problems) and considered 'legit.' Is there any way to prevent this?

• How is the Trac Project List page customised?

  - by Completenutter2

  We've been using Trac for a while now for our developers only. However we are now opening it up for our (internal) clients. We have a project listing page (based on the default one that comes with Trac). What we'd like to do, is display more information about the project than what is currently available. I have searched google and here, to see if I can find how to get more information. There seems to be a variable called $project which has .name, .description and .href as attributes. Is there somewhere, a list of the attributes available? Or perhaps a different solution altogether that will allow us to display more information on the project list page. Such as the number of open tickets etc.

• How to Implement Dynamic Timestamp in Web Page?

  - by Morgan Cheng

  In Facebook and twitter, we can see that there is a timestamp like "23 seconds ago" or "1 hour ago" for each event & tweet. If we leave the page for some time, the timestamp changes accordingly. Since it is possible that user machine doesn't have same system time as server machine, how to make the dynamic timestamp accurate? My idea is: It is always based on server time. When request is sent to server for the web page, timestamp T1 (seconds to 1970/1/1) is rendered into inline javascript variable. The displayed timestamp ("23 seconds ago") is calculated by T1 instead of local time. I'm not sure whether this is how Facebook/Twitter do it. Is there any better idea?

• Automatically create valid links

  - by Marcos Placona

  Hi, I'm new to python, so please bare with me :) I was wondering if there's any built-in way in python to append variables to URL's regardless of it's structure. I would like to have a URL variable (test=1) added to an URL which could have any of the following structures http://www.aaa.com (would simply add "/?test=1") to the end http://www.aaa.com/home (like the one above, would simply add "/?test=1") to the end http://www.aaa.com/?location=home (would figure out there's already a ? being used, and would add &test=1 to the end) http://www.aaa.com/?location=home&page=1 (like the one above, would figure out there's already a ? being used, and would add &test=1 to the end) I'd be happy to write domething to do it myself, but if python can already do it somehow, I'd me more than happy to use any built-in functionality that would save me some time ;-) Thanks in advance

• c style thread creation in python

  - by chandank

  Hi I am new to python and want to create multiple threads in a loop something like (in C style) for (;i < 10; i++) thread[i]= pthread_create(&thread[i],&attr,func) I am not sure how to do the same in python? Basically I want have that thread[] variable as global will create all thread at once and then will start then in once. I have written a similar python program that does it but I think having it in above style will be better. def thread_create(thread_number): command_string = "Thread-" + "%d" %thread_number thread = myThread(thread_number, command_string) thread.start() # Start new Threads for i in range(5): thread_create(i)

• PHP: Loop through text file and isolate lines which a specific "starting point"

  - by Mestika

  Hi everyone, I’m trying to reduce some editing time within some textfiles where there approximately are 10.000 lines of text, but I only need around 200 or some. The text file relies on a almost specific pattern but it deviates from time to time but my “focus” in order to select the right line to keep is, that the line always starts with: z3455 and then have a variable afterwards, e.g.: z3455 http://url.com/data1/data1.1/data1.3/ (342kb) I have an algorithm to capture the URL and its content but now I need some way to loop through the text file, deleting all lines except does that starts with z3455 and then “push” them together so they are listed underneath each other. I’ve tried different approaches for this in PHP but can’t seem to find a correct function. I can “isolate” a specific line number but when it deviates I can’t use this approach fully. I hope that someone can help me, either by providing the code or knocking me in the right direction to how I’ll solve this problem. Thanks in advance Sincerely - Mestika

• Django - Empty session data in ajax requests

  - by ninja123

  Hi guys, I have an ajax view where I want to set a session variable like such: def upload(request, *args, **kwargs): request.session['test'] = 'test' request.session.modified = True print request.session.items() I have another normal view something like this: def advertise(request): print request.session.items() I get these two strings printed to shell: [('test', 'test')] [('_auth_user_backend', 'django.contrib.auth.backends.ModelBackend'), ('_auth_user_id', 26L)] Why is the session data that I set in the ajax view not passing to my regular views? If I set session data in regular view, everything works as fine, but it seems that ajax requests contain empty session data? Anybody dealt with something like this before? Any suggestions are greatly appreciated. Thanks.

I want to pass them as parameters - any ideas how to get this to work?

• Parantheses around method invokation: why is the compiler complaining about assignment?

  - by polygenelubricants

  I know why the following code doesn't compile: public class Main { public static void main(String args[]) { main((null)); // this is fine! (main(null)); // this is NOT! } } What I'm wondering is why my compiler (javac 1.6.0_17, Windows version) is complaining "The left hand side of an assignment must be a variable". I'd expect something like "Don't put parantheses around a method invokation, dummy!", instead. So why is the compiler making a totally unhelpful complaint about something that is blatantly irrelevant? Is this the result of an ambiguity in the grammar? A bug in the compiler? If it's the former, could you design a language such that a compiler would never be so off-base about a syntax error like this?

• set and get variables throughout moive - actionscript 3

  - by ed209

  I need to set various variables depending on what a user clicks. Those variables then need to be accessed by other movieclips. The problem is that at the time of clicking, those "other movieclips" don't exist on the timeline yet. What I have done is assign the variable to the parent movieclip, although I guess I could just as easily set them to the root. Then I would grab that value when the relevant clip is initiated. // set - works MovieClip(parent).aMovieClip.someVariable = myVal; // get? - doesn't work getVar = MovieClip(parent).aMovieClip.someVariable; the above doesn't work - what is the correct way to get that value whenever I need it. I guess it's a case of getting and setting global variables

• Iterator category

• C# Count registry keys existing using a partial value

  - by cheeseman

  Microsoft.Win32.RegistryKey registryPath = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Testing"); Microsoft.Win32.RegistryKey entryKey = registryPath.OpenSubKey("Entry Point"); I have a lot of keys in Testing, in the format: "Entry Point 011", "Entry Point 123" - so Entry Point with random numbers after it. Would I be able to search the registryPath variable above and get a count of the number of keys containing the "Entry Point" keyword? Assuming that there are also other keys existing without this keyword. At the moment I have been using a for loop and looping for all possible combinations to get a count of all the keys, checking if the key exists or not, but as there are keys as high as "Entry Point 9000" having a for loop execute 9000 times is very inefficient. for (int i = 0; i <= highestEntryPointValue; i++) { Microsoft.Win32.RegistryKey entryKey = steamApps64.OpenSubKey("Entry Point " + Convert.ToString(i)); if (entryKey != null) { count++; } }
