• Step by step help and guidance

  - by ChrisC

  Is there such a thing as a paid (or free would be GREAT, but unlikely I'm thinking) resource that could help a newbie with guidance and help as I create my first app (C# with SQLite db)? Stackoverflow is great, but a one-on-one person who was familiar with exactly what I'm doing would be even better.

• Set item.selected in ASP.NET Menu Control

  - by BillB

  ASP.NET newbie here. When on a page I'd like to set the corresponding menu item to selected. My approach is this: On Home.aspx.cs: Menu menu = (Menu)Master.FindControl("Menu1"); if (menu.Items.Count > 0) { menu.FindItem("Home").Selected = true; } Trouble is, menu.item.count == 0. My menu is bound to a sitemap, if that matters. Thanks, Bill

• BetterAuthorizationSample weird???

  - by Nano8Blazex

  I have a quick, newbie question... I just started looking through authrozation services and Apple's BetterAuthorizationSample... for some reason, I just can't get the hang of it. For example... I deleted the HelperTool and InstallTool and SampleTool.c and all references, but why does the program seem to continue work like nothing happened at all even after a clean build? Even commenting out all the code in SampleTOol.c doesn't seem to affect the way the program runs? Thanks

  Hi, I am presenting a UIView with an animation that takes half of the screen. I've seen it in many apps but could not find the appropriate RGB colors: iOS uses it for example in "contacts": http://img98.imageshack.us/img98/9402/image001u.png I'm trying with : bottomLayer.backgroundColor = [[UIColor colorWithRed:80.0/255.0 green:86.0/255.0 blue:97.0/255.0 alpha:1] CGColor]; but it's all whitey. If anyone could get how this popup is designed... Thanks!

• Can I get a person's display name or composite name from Apple AddressBook on OSX platform?

  - by AlexT

  I have come across ABRecordCopyCompositeName() in these pages but, having Spotlighted it, have a hunch it's only available for the IOS platform. The AddressBook app itself, and ABPeoplePicker obviously do something similar internally, so is there an equivalent API for OSX? It's a tedious thing to retrieve title, first name, middle name, last name, suffix and work out if it's a company before building it yourself.

  - by user280454

  Hi, I'm a newbie to the world of ANN. I'm aware of the Gradient Desecent Rule and the Backpropagation Theorem. What I don't get is , when is using a bias important? For example, when mapping the AND function, when i use 2 inputs and 1 output, it does not give the correct weights, however , when i use 3 inputs(1 of which is a bias), it gives the correct weights.

• Path managment in Linux programs

  - by petersohn

  I have a newbie Linux programming question. Suppose I have a project that uses Autotools for compiling and deployment, and I have data files that are to be installed in a location like /var/something or /usr/share/something etc., but in Autoconf, I can change these installation paths. How should the program find these files? How does it know where they are actually installed (if anywhere, since the program should work even if not installed, but run from where it was built)?
