• iPhone: App crashes when I click on a cell in table view.

  - by Jack Griffiths

  Hi there, Compiling my application works—everything is fine. The only errors I get are by deprecated functions (setText). The only problem is now, is that when I tap on a cell in my table, the app crashes, even though it's meant to push to the next view in the stack. Any solutions are appreciated, if you need any code, just ask. Also, how can I only make sure that one cell goes to only one view? For example: When I tap on CSS, it takes me to a new table with different levels of CSS. WHen I tap on an item in that new view, it comes up with an article on what I just selected. Regards, Jack

• Can I prevent a user from using windows taskmanager to end a process?

  - by Russ

  I have a c# 4.0 application that I hear grumblings and rumors about problems with. Now, this application has a global unhandled exception handler that reports back to me with errors. I also know that it works because SOME people fill it in, and submit it. It seems though; that a large number of people do NOT fill it in, but instead, use the Windows Taskmanager to end the process. Is it possible to prevent a user from using the Windows Taskmanager to end a specific process? My goal would be that if the application crashes, the form that the user is presented with prevents the process from being ended. I'll also accept steps that would prevent the Windows Taskmanager from being launched.

• Alternative to Apache’s .htaccess file for IIS?

  - by user80151

  I'm moving a WordPress blog from Apache to IIS. It's just for a couple weeks until I get it changed out. But all I can get to is the homepage. Everything else throws errors. I think my problem is in the .htaccess file: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> #END WordPress Is there something equivalent to this for IIS? Thanks.

• File Encrypt/Decrypt under load?

  - by chopps

  I found an interesting article about encrypting and decrypting files but since it uses a file.dat to store the key this will run into problems when theres alot of users on the site dealing with alot of files. http://www.codeproject.com/KB/security/VernamEncryption.aspx?display=Print Should a new file be created every time a file needs decrypting or would there be a better way to do this? UPDATE: Here is what im using to avoid the locking problems. using (Mutex FileLock = new Mutex(true, System.Guid.NewGuid().ToString())) { try { FileLock.WaitOne(); using (FileStream fs = new FileStream(keyFile, FileMode.Open)) { keyBytes = new byte[fs.Length]; fs.Read(keyBytes, 0, keyBytes.Length); } } catch (Exception ex) { EventLog.LogEvent(ex); } finally { FileLock.ReleaseMutex(); } } I tested it on 1000 TIFFs doing both encryption and decryption without any errors.

• Which rdfa parser for java that supports currently used rdfa attributes?

  - by lennyks

  I am building an app in Java using Jena for semantic information scraping. I am looking for a RDFa parser that would allow me to correctly extract all the rdfa statements. Specifically, one that extracts info about namespaces used and presuming that rdfa tags are correct in the page produces correct triples, ones that distinguish between object and data properties. I went through all rdfa parsers from the site http://rdfa.info/wiki/Consume for Java. They all struggle to extract any rdfa statements and if they do not crash, Jena RDFa parser shows plenty of errors and then dies a terrible death, the data is of little use as it is incorrectly processed and generally mixed up. I am newbie in this area so please be gentle:) I was also thinking of using a library written in different language but then again I don't really know how to plug it into Java code. Any suggestions?

• Where can I find a jQuery color animation plugin?

  - by George Edison

  I need an up-to-date jQuery color animation plugin that works in IE 8. I tried using the one at http://plugins.jquery.com/project/color but it causes errors like "Invalid property value." in the following line of code from color.js: fx.elem.style[attr] = "rgb(" + [ Math.max(Math.min( parseInt((fx.pos * (fx.end[0] - fx.start[0])) + fx.start[0]), 255), 0), Math.max(Math.min( parseInt((fx.pos * (fx.end[1] - fx.start[1])) + fx.start[1]), 255), 0), Math.max(Math.min( parseInt((fx.pos * (fx.end[2] - fx.start[2])) + fx.start[2]), 255), 0) ].join(",") + ")"; Where can I get something that works? By the way, I really hate IE, if that helps.

• how to import other schema jars when using the scomp tool

  - by MikeJiang

  there is a huge amount of xml schemas for the business, some of them are common types like Money.xsd, Address.xsd, etc, while others are business specific like Customer.xsd, ShippingOrder.xsd, etc. So I decide to compile these schemas into 2 jars, one is commonbeans.jar, the other is businessbeans.jar. I've separated them into different folders. to build the commonbeans.jar is simple, just run "scomp -out commonbeans.jar ....\common*.xsd"; while run "scomp -out businessbeans.jar ....\business*.xsd" is a different story, there are errors say can't find those common types, and run "scomp -out businessbeans.jar ....\business*.xsd ....\business*.xsd" will blindly duplicate all the common types into the businessbeans.jar. so is there any way to link the commonbeans.jar when compile those busimess schemas, maybe something like "scomp -out businessbeans.jar ....\business*.xsd commonbeans.jar". I hope my poor english has expressed my issue!

• Batch convert latin-1 files to utf-8 using iconv

  - by Jasmo

  I'm having this one PHP project on my OSX which is in latin1 -encoding. Now I need to convert files to UTF8. I'm not much a shell coder and I tried something I found from internet: mkdir new for a in ls -R *; do iconv -f iso-8859-1 -t utf-8 <"$a" new/"$a" ; done But that does not create the directory structure and it gives me heck load of errors when run. Can anyone come up with neat solution?

• Algorithm for calculating definite integrals with bounds at infinity

  - by mbac32768

  Suppose I have an integral that's bounded on one (or both) end by (-)infinity. AFAICT, I can't analytically solve this problem, it takes brute force (e.g. using a Left Riemann Sum). I'm having trouble generalizing the algorithm so that it sets the proper subdivisions; I'll either do far too much work to calculate something trivial, or not do nearly enough and have huge aliasing errors. Answering in any language is cool, but maybe someone with better google-fu can end this quickly. :) Is what I'm looking for as impossible as trying to measure the British coastline?

• NSAutoreleasePool carrying across methods?

  - by Tim

  I'm building an iPhone application where I detach some threads to do long-running work in the background so as not to hang the UI. I understand that threads need NSAutoreleasePool instances for memory management. What I'm not sure about is if the threaded method calls another method - does that method also need an NSAutoreleasePool? Example code: - (void)primaryMethod { [self performSelectorInBackground:@selector(threadedMethod) withObject:nil]; } - (void)threadedMethod { NSAutoreleasePool *aPool = [[NSAutoreleasePool alloc] init]; // Some code here [self anotherMethod]; // Maybe more code here [aPool drain]; } - (void)anotherMethod { // More code here } The reason I ask is I'm receiving errors that objects are being autoreleased with no pool in place, and are "just leaking." I've seen other questions where people didn't have autorelease pools in place at all, and I understand why an autorelease pool is needed. I'm specifically interested in finding out whether an autorelease pool created in (in this example) threadedMethod applies to objects created in anotherMethod.

• javax.servlet import cannot be resolved after moving web servlet

  - by Michael Kjörling

  I have written a small web servlet to run under Tomcat, using Eclipse Helios. In its old, non-source-controlled location, everything was fine, but now I need to add this to our source control system. Moving the old files out of the way, creating a new workspace, setting up the server connection and copying and importing the existing projects into the new workspace all worked fine once I figured out how to do it, but I can't get the servlet to build. Instead, I get a whole bunch of cannot be resolved to a type errors talking about various servlet class types; HttpServlet, HttpServletRequest, ServletException, etc. Another error that is almost certainly related is The import javax.servlet cannot be resolved. I am obviously missing something very basic, but I'm new to this (and not having the terminology really down pat probably doesn't help me Google for an answer). Any suggestions as to what I might be missing would be greatly appreciated.

• C# ASP.NET Update database with datatable

  - by Sir Graystar

  Scenario: I'm just trying to update my database with the changes made by the user to their information. Here is my code: SqlCommandBuilder cb = new SqlCommandBuilder(da); dt.Rows[0][2] = txtname.Text; dt.Rows[0][3] = txtinterests.Text; dt.Rows[0][4] = txtlocation.Text; da.SelectCommand = new SqlCommand(sqlcommand, conn); da.Update(dt); I know its going to be something obvious, but what have I missed? There are no errors, everything compiles correctly, but nothing happens. The record remains unchanged.

• Strange error: cannot convert from 'int' to 'ios_base::openmode'

  - by Dylan Klomparens

  I am using g++ to compile some code. I wrote the following snippet: bool WriteAccess = true; string Name = "my_file.txt"; ofstream File; ios_base::open_mode Mode = std::ios_base::in | std::ios_base::binary; if(WriteAccess) Mode |= std::ios_base::out | std::ios_base::trunc; File.open(Name.data(), Mode); And I receive these errors... any idea why? Error 1: invalid conversion from ‘int’ to ‘std::_Ios_Openmode’ Error 2: initializing argument 2 of ‘std::basic_filebuf<_CharT, _Traits* std::basic_filebuf<_CharT, _Traits::open(const char*, std::_Ios_Openmode) [with _CharT = char, _Traits = std::char_traits]’ As far as I could tell from a Google search, g++ is actually breaking the C++ standard here. Which I find quite astonishing, since they generally conform very strictly to the standard. Is this the case? Or am I doing something wrong. My reference for the standard: http://www.cplusplus.com/reference/iostream/ofstream/open/

• Images saved with D3DXSaveSurfaceToFile will open in Paint, not Photoshop

  - by bsruth

  I'm using D3DXSaveSurfaceToFile to save windowed Direct3D 9 surfaces to PNG, BMP and JPG files. There are no errors returned from the D3DXSaveSurfaceToFile call and all files open fine in Windows Photo Viewer and Paint. But they will not open in a higher end image editing program such as Paint Shop Pro or Photoshop. The error messages from these programs basically say that the file is corrupted. If I open the files in Paint and then save them in the same file format with a different file name, then they'll open fine in the other programs. This leads me to believe that D3DXSaveSurfaceToFile is writing out non-standard versions of these file formats. Is there some way I can get this function to write out files that can be opened in programs like Photoshop without the intermediate step of resaving the files in Paint? Or is there another function I should be using that does a better job of saving a Direct3D surfaces to an image?

• hasErrors with indexed property

  - by Micor

  I am having hard time getting hasErrors to work with indexed properties. For example class Order { String prop1 String prop2 static hasMany = [items: Item] } class Item { String name static constraints = { name(blank:false) } } Validation works properly and on item.name being blank I do get an error with <g:renderErrors bean="${orderInstance}"/> However, I am trying to have input box highlighted using hasErrors : <g:each in="${orderIntsance.items}" status="i" var="item"> <span class="field ${hasErrors(bean: orderInstance, field: ????????? , 'errors')}"> <g:textField name="items[${i}].name" value="${item?.name}"/> </span> </g:each> Not sure how to get to it with a field: property, any ideas? Thanks

• Problem with dictionary key in Python

  - by Hossein

  Hi all, For some project I have to make a dictionary in which the keys are urls,among which I have this url: http://www.microsoft.com/isapi/redir.dll prd=windows&sbp=mediaplayer&ar=Media&sba=Guide&pver=6.2 the url is too long to fit in here I guess in one single line. there is a space between .dll and prd. I can build a dictionary without any errors this url is also a key. but for some reason when I want to extract the values associated to this key(url). I cannot, I get and error "error key:...." Does someone know what is wrong with this url? Are dictionary keys sensitive to some stuff? thanks

• golang dynamically parsing files

  - by Brian Voelker

  For parsing files i have setup a variable for template.ParseFiles and i currently have to manually set each file. Two things: How would i be able to walk through a main folder and a multitude of subfolders and automatically add them to ParseFiles so i dont have to manually add each file individually? How would i be able to call a file with the same name in a subfolder because currently I get an error at runtime if i add same name file in ParseFiles. var templates = template.Must(template.ParseFiles( "index.html", // main file "subfolder/index.html" // subfolder with same filename errors on runtime "includes/header.html", "includes/footer.html", )) func main() { // Walk and ParseFiles filepath.Walk("files", func(path string, info os.FileInfo, err error) { if !info.IsDir() { // Add path to ParseFiles } return }) http.HandleFunc("/", home) http.ListenAndServe(":8080", nil) } func home(w http.ResponseWriter, r *http.Request) { render(w, "index.html") } func render(w http.ResponseWriter, tmpl string) { err := templates.ExecuteTemplate(w, tmpl, nil) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) } }

• DataMapper: using auto_migrate! with many-to-many dependencies?

  - by pschuegr

  Hi, I'm trying to migrate my app from MySql to Postgresql, using Rails3-pre and the latest DataMapper. I have several models which are related through many-to-many relationships using :through = Resource, which means that DataMapper creates a join table with foreign keys for both models. I can't auto_migrate! these changes, because I keep getting this: ERROR: cannot drop table users because other objects depend on it DETAIL: constraint artist_users_owner_fk on table artist_users depends on table users constraint site_users_owner_fk on table site_users depends on table users HINT: Use DROP ... CASCADE to drop the dependent objects too. I have tried everything I can think of, and thought I had things working when I added :constraint = :skip to the field definition, but I keep getting that error back when I try and run auto_migrate. I thought that :skip meant that it would ignore the dependents, but maybe that only applies for deleting rows and not dropping tables? I should mention that I can run auto_migrate after i nuke the db once, but after that, errors. Any suggestions or advice much appreciated.

• How to simulate an error 500 in Symfony 1.4?

  - by Guillaume Flandre

  I created an error500.php file in web/errors/ and would now like to test it. I tried to put this line in one of my actions: $this->getResponse()->setStatusCode(500); Unfortunately it looks like it's ignored. Do you guys have any idea of what's happening here? I'm using Symfony 1.4. Edit: Firebug is telling me that the error is actually fired but the page is still loading afterwards. And I'm in the prod env.

• How to update user info with restful_authentication plugin in Rails?

  - by benoror

  Hi people, I want to give the users to change their account info with restful_authentication plugin in rails. I added this two methods to my controller: def edit @user = User.find(params[:id]) end def update @user = User.find(params[:id]) # Only update password when necessary params[:user].delete(:password) if pàrams[:user][:password].blank? respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' format.html { redirect_to(@user) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end Also, I copied new.html.erb to edit.html.erb. Considering that resources are already defined in routes.rb I was expecting it to work easily, bute somehow when I click the save button it calls the create method, instead of update, using a POST http request. Any ideas?
