• Cannot change UIImageView frame in a custom table cell.

  - by jkally

  I have a custom table cell. In it I have put (via the IB) an image view of a certain frame In 'cellForRowAtIndexPath', under certain conditions, I would like to modify the frame of this UIImageView, so I write something like: UIImageView *imgv = (UIImageView *)[cell viewWithTag:1]; CGRect r = CGRectMake(20.0, 20.0, 10.0, 10.0); imgv.frame = r; But nothing expected happens (The frame does move a little though not to where I want, but doesn't change its size at all);

• Extract Address Information from a Web Page

  - by Brian Boatright

  I need to take a web page and extract the address information from the page. Some are easier than others. I'm looking for a firefox plugin, windows app, or VB.NET code that will help me get this done. Ideally I would like to have a web page on our admin (ASP.NET/VB.NET) where you enter a URL and it scraps the page and returns a Dataset that I can put in a Grid.

• UpdateLayout throwing an ambigious exception

  - by Ouais

  the stack trace displays my method's name then "external code" then app_unhandledexception method, I'm developing within VS2008 SP1 for silverlight on firefox and windows 7(if that makes a difference). the weird thing is, the updatelayout method is called elsewhere and it generates no exception there, that said, if I put the method within a try-catch clause, it doesn't catch the exception, so if anyone has an idea, I'd appreciate it.

• SSIS with different table structures

  - by Grace

  I have a flat file source from Excel that has a structure like this: **People** Day1 Day2 Day3 Day4 Person1 someValue ... Person2 Person3 And i would like the package to put this information in a database with standard columns 'Person', 'Day', 'Value'. Does anybody know how to do this - at the moment because the days are going along the top, the package is assuming these are seperate data columns when they are not really and the mapping is not working.

  - by Shaza

  The title is obvious, I need to know if methods are serialized along with object instances in C#, I know that they don't in Java but I'm a little new to C#.

• Ajax auto-populate from field when another form field is filled out

  - by Jon

  Has anyone used javascript/ajax to take data from one form field and put it into another? I'm trying to create a form that when one text input is filled out a second is auto-populated with the first letter of the word that is in the first text input. I'm thinking I can limit the second text input to one character to help get the desired result, but I'm not having luck finding the javascript to get the second text input to auto-populate from the first. Any suggestions?

• MySQL: Digits (1.75) to Friendly Time (1 hour and 45 minutes)

  - by Nick

  In my MySQL database, I have a float field named "HoursSpent" with values like "0.25", "1.75", "2.5", etc. Is there a way that I can have my SELECT statement format those values in a friendly format like this?: 0.25 = 15 minutes 1.75 = 1 hour and 45 minutes 2.5 = 2 hours and 30 minutes The "HoursSpent" field is supposed to only have values in 0.25 increments, but if somebody were to put something random like 0.16, it would be nice if the SELECT statement handled that by rounding it up to the nearest 0.25 (so in this case 0.16 would become 0.25, or 15 minutes).
