  • Display "custom" view (various images, various text). Should I use UIWebView?

    - by aw
    First: No, none of the content should be loaded from the web. All content parts are shipped with the main bundle. I have n images and mass of text (including lists). Instead of building all view parts programmatically in objective-c if was thinking of using an UIWebView and build "only" the HTML dynamically. Does anything speaks against it? How does UIWebView work with local content? Links and resources welcome. Thanks

  • Is there a tool that will show diagrams of my SQL database in real-time?

    - by Rising Star
    I've created some diagrams of SQL tables using the "Reverse Engineer" feature of Microsoft Office Visio. I like being able to visualize my relational databases in this manner. However, what I get is just a static document that I can print, e-mail to colleagues, and click widgets on. Earlier this year, I saw at a demo that the new version of Visual Studio 2010 has a new feature called the "Architect Explorer", which allows developers to view relationships among .net classes on the fly. It has many features for filtering the data that the developer is interested in. It would be really awesome if I could visually browse my tables and stored procedures and see what is related to what by primary key, foreign key, and referenced in stored procedures. I realize that I'm talking about two entirely different technologies and it's not a perfect analogy, but is there some similar tool that would allow me to visualize tables in my SQL database?

  • How can i share data/text with other apps that will accept it?

    - by kefs
    I have an app that creates a new data entry in a sqlite db with several columns. I would like to have a simple share button on the final activity so they can share the results (or even a simple text field) with apps that accept it (email, mms, twitter, etc..). I did some reading on ContentProviders but the more I read, the more I'm thinking i'm heading down the wrong path. Any help is appreciated. Thanks!

  • providing a java servlet with information

    - by tom
    Hi, i am new to servlets. I made a simple hello world programme that prints those famous 2 words to the screen when i access the page via a browser using http://localhost:8080/mypath/path... My question is now, how do i provide a servlet with information? Specifically considering the fact that my c# programme calculates a lookup value for a global system, then the "java" servlet processes that and returns a set of results. I have done the reverse thanks to help on here, regarding calling a returned string from the java servlet in c#. However i am not sure how i go about providing the servlet information. Do i pass it via the url? Thank you

    I am trying to deserialize a field: "presenters":[{...},{...}] but some of the rows come back with only: "presenters":"" When the serializer gets to the row with that empty string I get: Error converting value "" to type 'System.Collections.Generic.List`1[DataPrototype.Model.Presenter]'. Am I right in thinking that I need a JsonConverter that will change the empty string into an empty List?

  • VMware convert to Virtualbox?

    - by TechSavvySmurf
    I downloaded a Kali Linux ISO VMware image thinking that it would be able to run in Virtualbox as well. However, this only seems to be the case with .vmdk files, and my image is a .vm.tar.gz file. Virtualbox does not recognize it as a valid ISO file, and I am not sure how to convert it. The entire thing is kali-linux-1.0-i386-gnome-vm.tar.gz The goal is to be able to run this in a Virtualbox, is there any way to convert this from VMware to Virtualbox?

  • Generate 3 random number that sum to 1 in R

    - by user1034797
    I am hoping to create 3 (non-negative) quasi-random numbers that sum to one, and repeat over and over. Basically I am trying to partition something into three random parts over many trials. While I am aware of a= runif(3,0,1) I was thinking that I could use 1-a as the max in the next run if, but it seems messy. But these of course don't sum to one. Any thoughts, oh wise stackoverflow-ers?
