How do I remove database name from SQL Server generated script?
- by bucha
Anytime I use 'script table as' - 'Insert To' (or other command), the script generated automatically places the database name in the script. Such as: INSERT INTO [DatabaseName].[dbo].[tblToBeInserted] ... While not a huge problem to just delete it, it has slipped by a few times and the script breaks if run on a different server with a different database name but has the same schema. (Such as running on [DatabaseName.Test]) Is there an option I can change, or can I modify the output in any way to remove this?Read the article

Tracking image views - PHP
- by RS7
I'd like for my app to be able to tell if an image hasn't been viewed in the last 30 days and remove it (along with data in the DB associated with it). I know you can have PHP read and output the image dynamically but I've heard its quite taxing on the system. Is there a way to for me to track these hits even when the image is viewed directly? (would htaccess be able to do this?) Thanks in advance.Read the article

when to use const char *
- by djones2010
If i have a function api that expects a 14 digit input and returns a 6 digit output. I basically define the input as a const char *. would that be the correct and safe thing to do? also why would I not want to just do char * which I could but it seems more prudent to use const char * in that case especially since its an api that i am providing. so for different input values I generate 6 digit codes.Read the article

var Dog = function() { var _instance = 'hello world'; return function() { console.log(this._instance); } } (); //note that it is self invoking function var l = new Dog(); //#> undefined In the above case I was expecting output of 'hello world'.

Port AS3/Flex app to iPhone
- by John
I believe Adobe tools like CS5 have ways to output as an iPhone app, but what about a regular AS3 or Flex project? Are there any tools to auto-port, or AS3/Flex iPhone implementations out there? Out of interest, how does the CS5 thing work? Is it a totally different code-path or something less drastic? For instance Flash supports Shapes and Timelines, etc... do they in fact provide an iPhone Flash runtime of some sort?Read the article
