  - by Tom

  Hi! I'm a web developper/objective-c developper and I'd like to learn quickly to make some apps for windows. I say quick because I'm used to learning many languages and I don't need any overview on concepts, patterns, etc. Any answers will be very appreciated :) Thanks!

• Export to Excel in Asp.net MVC

  - by BigJoe714

  I am working on an ASP.NET MVC application where I need to export data to an excel spreadsheet. Previously, in webforms apps, I used some code I found to render a GridView as an excel-compatible file. This was quite handy.

• Use Network Services for FDT

  - by WillDonohoe

  Hi everybody, I've recently started using FDT, for a while I was using FlashDevelop, it had a really handy feature in Compiler options where you can set UseNetworkServices to false which would stop the compiled swf from connecting to the internet and became very useful for running standalone flash apps without security warnings when loading in an external xml file etc. Does anybody know if FDT has a similar function? If there isn't a way, then no worries, I can compile the project in Flash Develop, however it would be best if I can do it from FDT. Cheers guys, Will

• MySQL - What is the correct primary key method

  - by Hammerstein

  I'm starting to develop an application using MySQL and although I've developed apps before using databases, I've normally gone to the incrementing id method. The other day I was reading a posting somewhere and saw someone being picked apart for this, for not properly "normalising the database". I'm not a big database person, but I wanted to make sure I'm doing this right. Any ideas, help / guidance?

  - by Phamer

I also have seen them on the Facebook app and some other custom apps. I am surprised that they are not built in "UIBarButtonSystemItem" icons. Can anybody point me to these icons?

• .NET Compact Framework app that will run on both Professional and Standard

  - by CJCraft.com

  Is there any guidance on creating apps that will run on both professional (touch-screen) and standard (non-touch-screen) devices. I have a simple application that is mostly text and buttons that in theory should be able to run on both professional and standard devices with little if any modification. It seems the IDE wants to make this hard to impossible, but I expect it to be possible. Any advice?

  Problem: I want to make iPhone OS 2.1 apps, but Xcode now always makes automatically an iPhone OS 3.0 project. I forgot about it and now I have an app which I want to test on my iPod touch, but I need to build OS 2.1. Is there a way to get this working? The dropdown from top left in Xcode only offers to build for OS 3.0 device. However, when I open old projects, there I have OS 2.1 available.

• Do I need to create icons other than RGBA for my Windows app?

  - by user843732

  I'm curious if anyone still creates icons other than RGB/A (or 32-bit with alpha-channel) for your Windows apps? PS. I know that suggested model is to create 256-color versions of icons, but I always struggle with those. If I automatically convert them in an icon editor they totally decimate the look of my original icons with jagged edges and circa-Windows95 look. So if those are still required, does anyone know the stats on how many people are still using color settings other then 32-bit TrueColor?

• What type of programs are C/C++ used for now?

  - by Ryan Detzel

  I started off with C in school, went to Java and now I primarily use the P's(Php, Perl, Python) so my exposure to the lower level languages have all but disappeared. I would like to get back into it but I can never justify using C over Perl or Python. What real-world apps are being built with these languages? Any suggestions if I want to dive back in, what can I do with C/C++ that I can't easily do with Perl/Python?
