• wrong font in a RichTextBox importing from .rtf

  - by giacomellow

  Hi all, I'm developing a microsoft surface application using expression blend+vs 2008. I have a RichTextBox that loads formatted text from an .rtf file. The text is formatted with uppecases, color, and specific font (helvetica-neue). When i load the text, it is displayed in the control with matching format (color and uppecase) but NOT matching font. it seems to use the standard Blend font (Thaoma). the text is loaded with this function: public static RichTextBox SetRTFText(string text, RichTextBox richTextBox) { MemoryStream stream = new MemoryStream(ASCIIEncoding.Default.GetBytes(text)); TextRange documentTextRange = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd); documentTextRange.Load(stream, DataFormats.Rtf ); return richTextBox; } thank you all!

• ModelName(django.contrib.auth.models.User) vs ModelName(models.Model)

  - by amr.negm

  I am developing a django project. I created some apps, some of those are related to User model, for instance, I have a feeds app that handles user feeds, and another app that deals with extra user data like age, contacts, and friends. for each of these, I created a table that should be connected to the User model, which I using for storing and authenticating users. I found two ways to deal with this issue. One, is through extending User model to be like this: ModelName(User): friends = models.ManyToMany('self') ..... Two, is through adding a foreign key to the new table like this: ModelName(models.Model): user = models.ForeignKey(User, unique=True) friends = friends = models.ManyToMany('self') ...... I can't decide which to use in which case. in other words, what are the core differences between both?

  - by Amr Mekkawy

  I'm working on a php project.. And I started building the admin login system and have already finished it and it works properly on my machine (local server) where I'm developing the project.. But when I moved it to a (web server) it didn't work properly as it was working on (local server). the problem that showed up is that when the admin get authentication to log in to the admin area, once he clicks any link in the page or even he reloads the page that page disappear and the login page appear again which mean the admin forced to log out even he didn't.

• Create a hyperlink of a slanting image in expression Blend

  - by Tony Bolding

  I am developing a navigation menu in silverlight that has 6 images. As you mouseover each image grows and clicking on an image will take you to a page on the website. The customer I am doing this for decided that straight rectangular images were boring and I showed him a design where I have slanted each image so each one is now a rhomboid shape. Horizontal top and bottom with sides slanting about 30deg from vertical. I have been unable to figure out any way of growing each image on mouseover without putting a white block over the adjacent images. Would be grateful for any pointers.

• mysql date format with changing string value

  - by hacket

  I have a field called Timestamp, that stores its values as text as opposed to an actual Timestamp. The logging application is unchangeable, unfortunately. So table.Timestamp -> text field with format -> "Wed Mar 02 13:28:59 CDT 2011" I have been developing a query to purge all but the most recent row using this as my Timestamp selector, which is also converting the string into a date - MAX( STR_To_DATE( table.Timestamp , '%a %b %d %H:%i:%s CDT %Y' ) My query works perfectly... However, what I've found is that the string value - 'CDT' - changes between 'CDT' and 'CST' depending on whether the current time is daylight savings time or not. During daylight savings time, it logs as 'CDT', and vice versa. So all the rows that contain 'CST' get ignored when I run this - MAX( STR_To_DATE( table.Timestamp , '%a %b %d %H:%i:%s CDT %Y' ) and all the rows that contain 'CDT' get ignored when I run this - MAX( STR_To_DATE( table.Timestamp , '%a %b %d %H:%i:%s CST %Y' ) Is there a way to make it run against both string formats?

• How to avoid web server traffic peak resulting from iOS Newsstand app receiving a remote notification?

  - by thomers

  I'm developing an iOS Newsstand app. If it is suspended or not running and connected to a WLAN, Newsstand apps can be triggered by a Push remote notification to download the latest issue (in our case around 100MB) in the background. I'm using Urban Airship for the delivery of the Push broadcast. I'm now worrying about many many iOS devices hitting the web server for one big download more or less at the same time, because I expect the majority of the devices will receive the notification in a very short timeframe. Instead of broadcasts to all devices, should I rather send individual notifications to batches of small groups of devices, spreading them out over a longer period of time? And/or would a CDN like Amazon Cloudfront solve that issue easier/anyway?

• Browsing page siblings through next/previous links

  - by Pieter

  I'm using WordPress as CMS for a site I'm developing. When I'm browsing posts, I can use Next/Previous links to walk between posts. I want to have the same thing on pages. Page A Page B Page C Page A should link to next sibling Page B. Page B should link to previous sibling Page A and next sibling Page C. Page C should link to previous sibling Page B. Is there any plugin you can recommend that generates these links? I know there are some plugins that do this, but I specifically want one that hooks into my current theme automatically. I know how to edit the theme, but that would brick my site whenever a theme update is available. I'm using the LightWord WordPress theme.

• Why is iphone Simulator not rendering HTML5 page correctly?

  - by user364978

  hello all, I have a page I am developing in .net using HTML5 intended for a WebView in an iphone App. The page looks just fine in Safari. When I load it in the iphone Simulator it is rendering as plain text, no styles or js loading. I thought it might be an issue with .net, but seeing as it works in Safari i am stumped. When I use the XHTML doctype it works just fine in the Simulator. Any ideas why this is occurring and what the fix may be? Thanks!

• hiding inner class implementation using namespace

  - by Abruzzo Forte e Gentile

  Hi all I am developing a library and a would like to provide my users a public interface separate from the real implementatino that is hidden in a namespace. This way, I could change only the class HiddenQueue without changing myQueue that will be exposed to users only. If I put the C++ code of HiddenQueue in the myQueue.cpp file the compiler complains saying _innerQueue has incomplete type. I thought that the linker was able to resolve this. What I am doing wrong here? Thanks Afg // myQueue.h namespace inner{ class HiddenQueue; }; class myQueue{ public: myQueue(); ); private: inner::HiddenQueue _innerQueue; }; /////////////////////////// // myQueue.cpp namespace inner{ class HiddenQueue{}; };

• How to pass Remote Interface (aidl) throughout Activities ?

  - by Spredzy

  Hi All, I am developing an application using services and Remote interface. I have a question about passing the reference of my Remote interface throughout Activities. In my first Activity, I bind my service with my activity, in order to get a reference to my interface I use private ServiceConnection mConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName arg0, IBinder service) { x = X.Stub.asInterface(service); } @Override public void onServiceDisconnected(ComponentName arg0) { // TODO Auto-generated method stub } }; x being the reference to my interface. Now I would like to access this interface from another activity, I see two ways to do it but I don't know which one is the "proper" way to do it : passing x with my intent when I call the new Activity redo this.bindService(new Intent(y.this,z.class), mConnection, Context.BIND_AUTO_CREATE); in the onCreate() of my new Activity What would you advice me to do ?

• Displaying Map ONLY when the button is clicked in Xcode

  - by Susanth

  Hi, I am developing an iPhone application using XCode and I am kinda stuck with the functionality described in the subject of this post. I want the map(using MapKit) to only load and display after I click a button. So, what code should I have under that my "(IBAction) showMap" function? Whatever I could find online talks about unhiding the map. I want to only load the map when a button is clicked rather than loading the map in the background and simply unhiding it the click of the the button. Thanks ! ~Susanth

  Hi. I have been developing android apps out of hobby and fun. I want to get more serious about android development. One particular thing that I am very keen on doing (or atleast trying my hand at) is andoroid ROM development for specific handsets. Like, maybe outdated HTC Touch. (Elf/Elfin). I am at a loss to understand, what does it take to get started in right direction and what does it entails? I would really appreciate your help if you could point me to some resources which would highlight ROM Development for Android specifically. (Fundamentals of ROM development irrespective of OS would help too). Cheers

• I want to retrieve some information based on Caller ID

  - by Hassan Al-Jeshi

  Hello, my friend has a Real Estate company that receives a lot of phone calls everyday. He wants to have a solution such that when somebody call to his company, the operator sees all the information about the person who is calling based on the database he have right now and the caller ID. Is there a ready made software or solution that can do the job?? Since I'm a software engineer myself, I would never mind developing something from scratch or built on a ready made system (with a team of course), but I need some direction on how to start?? Notes: 1- cost is not an issue 2- the customers database is there but we never mind replacing it in a format to suit the new solution Best Regards,

• Approach to data wrapping

  - by Mikhail

  I'm developing in PHP and MySQL. The information about the currently logged in user is stored in many different tables. The information that I need on each page, I preload. However if something is needed from a rarely accessed table - then I do $newdata = $db->Query('SELECT * FROM rare_table WHERE user_id='.$user->id); I would like to simplify the above to a point where I don't have to specify that the query should be limited to this particular user. An ideal function call would be: $newdata = $user->Query('SELECT * FROM rare_table'); Obviously I'd have to parse the SQL and add a WHERE clause. Or add to the already existing clause. Questions: are there tools to do this? How can I develop this? Is this even a good idea?
