  • Bind Grid.Row / Grid.Column inside a DataTemplate

    - by Thorsten79
    Hope this is not a dupe. I would like to be able to do the following in XAML: <DataTemplate DataType="{x:Type NewGACCTestApp:ButtonVM}"> <Button Grid.Column="{Binding GridColumn}" Grid.Row="{Binding GridRow}" Content="{Binding Path=Info}" /> </DataTemplate> The Content binding works fine but Grid.Column and Grid.Row simply don't exist in the produced object. Not even when I set them to some value without binding (like in Grid.Column="1"). I've snooped the application and saw that inside my grid nobody ever sets Grid.Column and Grid.Row. Any ideas?

  • How to get the line number an xml element is on via the Java w3c dom api

    - by Benju
    Is there a way to lookup the line number that a given element is at in an xml file via the w3c dom api? My use case for this is that we have 30,000+ maps in kml/xml format. I wrote a unit test that iterates over each file found on the hard drive (about 17GB worth) and tests that it is parseable by our application. When it fails I throw an exception that contains the element instance that was considered "invalid". In order for our mapping department (nobody here knows how to program) to easily track down the typo we would like to log the line number of the element that caused the exception. Can anybody suggest a way to do this? Please note we are using the W3C dom api included in the Android 1.6 SDK.

  • Postfix Bounced Emails With Google Apps

    - by crontab
    So our company uses Google Apps to handle our accounts for our employees. Meaning something like [email protected] would go to Google Apps. We also use postfix on our server to send out our news letter emails to our users. We've setup our emails to have a unique return-path which is basically [email protected] problem is that when postfix gets a bounce during the SMTP connection, it actually sends out the email to Google Apps. Is there anyway that we can setup Postfix to not send to [email protected] and instead pipe that message to a script which we can grab the original message and log the bounced address? I realize this only partially works as some emails may send correctly from postfix and then bounce down the road somewhere, but this should help us out with a good portion of our bounces. For a start, in main.cf we have recipient_delimiter = + and in master.cf we have bouncehandler unix - n n - - pipe user=nobody argv=/path/to/bounce_handler.php ${recipient} Not really sure where to go from here though.

  • What is the best way to keep database data encrypted with user passwords?

    - by Dan Sosedoff
    Let's say an application has really specific data which belongs to a user, and nobody is supposed to see it except the owner. I use MySQL database with DataMapper ORM mapper. The application is written in Ruby on Sinatra. Application behavior: User signs up for an account. Creates username and password. Logs into his dashboard. Some fields in specific tables must be protected. Basically, I'm looking for auto-encryption for a model properties. Something like this: class Transaction include DataMapper::Resource property :id, Serial property :value, String, :length => 1024, :encrypted => true ... etc ... belongs_to :user end I assume that encryption/decryption on the fly will cause performance problems, but that's ok. At least if that works - I'm fine. Any ideas how to do this?

  • iPhone SDK: How do I programatically change the background image of a UIButton added to a NIB?

    - by user304583
    I've seen several questions/answers related to entirely creating a button in code, but not one which would let me know how to change the button image in code, when I originally added the button to my NIB in Interface Builder. I know how to change the background in Interface Builder.. but I want to change it in code, so I can change it automagically. Any help really appreciated! Perhaps the answer is so obvious nobody needs to ask.. if so please forgive the dweeb that I am and help! :-)

  • What is tha CAUSE of Error 523 and Error 200 in Blackberry handhelds

    - by voipsecuritydigest.com
    I'm Blackberry developer, customers using my application experiencing Error 523 and Error 200. Remedies to those errors are in first case - remove application, my application. In second case totally reload OS! This is very bad, and customers blame me! But this is I don't do anything illegal to make blackberry crash. I just used a lot of memory, which is obvious because customer want that. Everywhere including Blackberry knowledge base people talking how to fix the problem, which may happened to everybody using application from well known brands, for example Yahoo! finances. But nobody explains what is the mechanism behind this, and if it is possible to avoid the problem. I would like to know what is that CAUSE of Error 523 and Error 200?

  • is it possible to use a python scrapper in a website?

    - by Tom
    I want to scrap a website and use that content in a website of my own. I am just wondering if that can be done with python 2.7, and if so how? If not, do I have to use JavaScript to scrap it? And do you have a good place to learn how to do that or good libraries for it. For those of you wondering, the website I am scrapping is legal, and they allow for this to be done. I have searched all over but apparently nobody tries to implement these scrappers that they write. I can write a web scrapper in python just fine. Say my scrapper scraps a name from a wikipedia page (John Doe for example), how can I use that name that I get in my website? Another update, I have found pjsrape and PhantomJS. I have only found one stack overflow post and the github examples with aren't very intuitive. If anybody has any experience or better ways to do it I would very much appreciate it

  • Simplest method of hiding sensitive information

    - by drozzy
    What is the simplest way I can hide a sensitive identifier, while providing some equivalent means of identifying the data from outside? For example, lets say I have a database table with records and one of them is an sensitive ID field. ID 2A 1S etc... then I want to have a second record: ID PublicID 2A AXXX44328 1S KKKZJSAAS such that when I am given a PublicID I can always determine what ID it refers to: H(PublicID) = ID but nobody else is able to do so. I suspect this is like, encryption - with throwing away a public key?

  • Who deleted my sql table rows?

    - by vikasde
    I have an SQL table, from which data is being deleted. Nobody knows how the data is being deleted. I added a trigger and know the time, however no jobs are running that would delete the data. I also added a trigger whenever rows are being deleted from this table. I am then inserting the deleted rows and the SYSTEM_USER to a log table, however that doesnt help much. Is there anything better I can do to know who and how the data gets deleted? Would it be possible to get the server id or something? Thanks for any advice. Sorry: I am using SQL Server 2000.

  • Should default passwords always be empty?

    - by mafutrct
    I'm currently designing a system that requires an admin to log in using a password. For certain reasons, it is difficult to set this password during installation, but it can be changed later. My idea is this: If I leave the default password empty, it is so horridly insecure that every admin is going to fix this as soon as possible. If I were to use some kind of predefined password instead, admins may think "ah.. nobody would think I've got 'defaultpassword' as my password so it's not very important to change." So the basic thought is to make it so terrible that even the most lazy people are going to do something about it.

  • this == null; surely not, but yes

    - by pm100
    I would have said that this will segfault but apparently not #include <stdio.h> class foo { public: bool thingy() {return this == 0;}; }; int main() { foo *f = 0; if(f->thingy()) printf("eating hat\n"); } I just expect that 0-xxx will never work. I assume that if we had to do some vtabling it would fail; obviously cannot access any member variables either edit; sorry - no question there. THe question is "are you surprised like me?" and it seems the answer is yes. even though nobody said yes. I got a) of course this will work b) of course this will never work c) it is undefined behavior; your mileage will vary

  • Do encryption algorithms provide really unique results?

    - by Mikulas Dite
    I was wondering whether md5, sha1 and anothers return unique values. For example, sha1() for test returns a94a8fe5ccb19ba61c4c0873d391e987982fbbd3, which is 40 characters long. So, sha1 for strings larger than 40 chars must be the same (of course it's scrambled, because the given input may contain whitespaces and special chars etc.). Due to this, when we are storing users' passwords, they can enter either their original password or some super-long one, which nobody knows. Is this right, or do these hash algorithms provide really unique results - I'm quite sure it's hardly possible.

  • OSError: [Error 1] Operation not permitted

    - by user1357576
    I am trying to run a python script which uses a binary file (xFiles.bin.addr_patched) created by a postlinker. However, I am getting this error. File "abc.py", line 74, in ParseCmd shutil.copy(gOptions.inputX, gWorkingXFile) File "/usr/lib/python2.6/shutil.py", line 89, in copy copymode(src, dst) File "/usr/lib/python2.6/shutil.py", line 66, in copymode os.chmod(dst, mode) OSError: [Errno 1] Operation not permitted: 'myPath/xFiles.bin.addr_patched' When I checked the permissions of this xFiles.bin, by ls-l, it shows that -rwxrwxrwx 1 nobody nogroup I presume the error is because this file was created by some other application, the python script I am running does not have access to it. Since I am beginner wrt ubuntu, I don't really know how to fix it. Any suggestions on how to fix this? SOLVED: As one of the answers Suggested : chown username:groupname file name fixes this issue

  • So where is this calling super?

    - by dontWatchMyProfile
    From the Core Data docs: Inheritance If you have two subclasses of NSManagedObject where the parent class implements a dynamic property and its subclass (the grandchild of NSManagedObject) overrides the methods for the property, those overrides cannot call super. @interface Parent : NSManagedObject @property(nonatomic, retain) NSString* parentString; @end @implementation Parent @dynamic parentString; @end @interface Child : Parent @end @implementation Child - (NSString *)parentString { // this throws a "selector not found" exception return parentString.foo; } @end very, very funny, because: I see nobody calling super. Or are they? Wait... parentString.foo results in ... a crash ??? it's a string. How can that thing have a .foo suffixed to it? Just another documentation bug?

  • How to stop my emails to be sent as bulk email?

    - by SH
    I have a reason to do that. I have recorded a voice message, attached with email, and sent it to several companies. One company, takes that voice message/email, and send it to millions of people. I want to stop resend of my email/voice recording. I am C# develop, one of my client asked me this question. I asked him to introduce verification codes, so that nobody will be able to listen the voice but still emails would be sent to millions of poeple. Any workaround for this problem?

  • How secure is encryption?

    - by Stomped
    Let me preface this by saying I know nothing about encryption. I understand the basic concept of public key / private key encryption but I don't how easily it can be broken, if at all. If one were to believe the movies, encrypted data can be broken by a teenager with a decent computer in a few hours. I have a client who wants credit card information sent via email - encrypted of course, but I'm still not feeling terribly good about the idea. I feel it would be safer to store the info on the VPS, but even then its an unmanaged server and there's nobody watching it who knows much about security. So can anyone tell me if there's a safe way to store and/or send this data out? Thanks

  • A Tkinter StringVar() Question

    - by Graham
    I would like to create a StringVar() that looks something like this: someText = "The Spanish Inquisition" #Here's a normal variable whose value I will change eventually TkEquivalent = StringVar() #and here's the StringVar() TkEquivalent.set(string(someText)) #and here I set it equal to the normal variable. When someText changes, this variable will too... HOWEVER: TkEquivalent.set("Nobody Expects " + string(someText)) If I do this, the StringVar() will no longer automatically update! How can I include that static text and still have the StringVar() update to reflect changes made to someText? Thanks for your help.

  • How to make large List & Label template?

    - by codymanix
    We want to have a form which contains lots of fields one over another. All of them are passed as parameters to the form. There are many condition formulas which determine whether one element is shown or not. Depending on how many fields are shown the result will get a different number of pages. The problem is, that the designer will only allow us to design on on single page with a fixed height. But we need more space to place fields there, because they are too many of them. Is there a way to enlarge the designer working area? Sure, a possible workaround is to choose a large paper format when in dessiger which will enlarge the working area and then reset it to A4 (Standard paper format), but even this will not be enough for us in some cases. Does nobody know an answer?

  • Android API Target Level 5 and 6 for Ubuntu

    - by Sebi
    Today i installed Ubuntu 10.4 and Eclipse Galileo. Then I downloaded the Android SDK and tried to install all packages via the Android SDK Tools. But unfortunately, only the Target Levels 3, 4, 7 and 8 were available. API Level 5 and 6 are missing. Does anybody know the reason for this? I already did a Google search and there seems to be nobody with the same problem. I also tried to restart it and nothing happens, the API Levels are still missing.

  • JAAS : on Callback ( Interesting based on HTTP headers )

    - by VJS
    I am using NameCallback and PasswordCallback for username and password.For username and password, popup comes on browser and when i enter username ans password, JAAS authenticates my request. On the wireshark, I have seen that 401 Unauthorized message (WWW-Authenticate header)comes and when i enter username/password HTTP request with credentials generate ( with Authorization header) and goes to server. My requirement : I don't want pop up to come.My application on other server having username / password, so once it received 401 then based on some logic it will generate HTTP request with Authorization header / credentials and sent it back. FLow : User - Other Server - My Tomcat5.5 Here on Other Server, nobody is available to enter username/password manually.Application is deployed and it will only generate HTTP request with credential and sent it back to tomcat. Can we have any other callback which behave like this.Need your help.Please provide me feedback as well related to approach.

  • How to limit memory of a OS X program? ulimit -v neither -m are working

    - by hectorpal
    My programs run out of memory like half of the time I run them. Under Linux I can set a hard limit to the available memory using ulimit -v mem-in-kbytes. Actually, I use ulimit -S -v mem-in-kbytes, so I get a proper memory allocation problem in the program and I can abort. But... ulimit is not working in OSX 10.6. I've tried with -s and -m options, and they are not working. In 2008 there was some discussion about the same issue in MacRumors, but nobody proposed a good alternative. The should be a way a program can learn it's spending too much memory, or setting a limit through the OS.

  • 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

  • What does a mercurial revision with no parent mean?

    - by Wilka
    I have a Mercurial repository that is in a strange state now. This is what it looks like in TortoiseHG: I didn't think this would be possible. Revision 54 has a parent of "-1 (000000000000)" (i.e. nothing). There's clearly something I don't understand yet about Mercurial, can anyone let me know what this means - and what must have happened for it to get into this state. As far as I know, it's only had stuff pushed and pulled from it - and nobody has been using any wacky extensions. Revisions 54 and 55 were just adding tags, but if I 'update -C' to revision 54 I end up with ONLY the .hgtags file. I've made a clone from revision 53 to fix this. But I'd rather understand what happened here, so I can avoid it happening again.

  • Tron: Legacy, 3D goggles, and embedded UA

    - by Roger Hart
    The 3D edition of Tron: Legacy opens with embedded user assistance. The film starts with an iconic white-on-black command-prompt message exhorting viewers to keep their 3D glasses on throughout. I can't quote it verbatim, and at the time of writing nor could anybody findable with 5 minutes of googling. But it was something like: "Although parts of the movie are 2D, it was shot in 3D, and glasses should be worn at all times. This is how it was intended to be viewed" Yeah - "intended". That part is verbatim. Wow. Now, I appreciate that even out of the small sub-set of readers who care a rat's ass for critical theory, few will be quite so gung-ho for the whole "death of the author" shtick as I tend to be. And yes, this is ergonomic rather than interpretive, but really - telling an audience how you expect them to watch a movie? That's up there with Big Steve's "you're holding it wrong" Even if it solves the problem, it's pretty arrogant. If anything, it's worse than RTFM. And if enough people are doing it wrong that you have to include the announcement, then maybe - just maybe - you've got a UX and/or design problem. Plus, current 3D glasses are like sitting in a darkened room, cosplaying the lovechild of Spider Jerusalem and Jarvis Cocker. Ok, so that observation was weirder than it was helpful; but seriously, nobody wants to wear the glasses if they don't have to. They ruin the visual experience of the non-3D sections, and personally, I find them pretty disruptive to the suspension of disbelief. This is an old, old, problem, and I'm carping on about it because Tron is enjoyable mass-market slush. It's easier for me to say "no, I can't just put some text on it. It's fundamentally broken, redesign it." in the middle of a small-ish, agile, software project than it would be for some beleaguered production assistant at the end of editing a $200 million movie. But lots of folks in software don't even get to do that. Way more people are going to see Tron, and be annoyed by this, than will ever read a technical communication blog. So hopefully, after two hours of being mildly annoyed, wanting to turn the brightness up, and slowly getting a headache, they'll realise something very, very important: you just can't document your way out of a shoddy UI.
