How to install .ipa file to iPad and iPhone?

We distribute our iPhone and iPad applications in an .zip or .ipa file to our clients for testing in an ad-hoc group. There is no need to speak about .zip file. The .ipa filename extension is assigned by Apple for applications that are downloaded from iTunes App Store. While we are developing your application, we usually email one of these files directly to you without interacting with App Store. We attach a second file – a .mobileprovision profile – to be able to join the ad-hoc group. This second file that contains your device UDID is needed to allow the application to run on your iPhone.

Bloomberg has reported today “that Apple Inc. will give software developers more leeway in how they create applications for its iPhone and iPad, a move likely to benefit Adobe Systems Inc. those software had been panned by Apple’s Steve Jobs.” Xcode may not be the only tool to develop iPhone apps, and finally Apple and Adobe will work on Flash issues as well. We discussed it earlier. See Slow Script error… and Flash story. Continue reading →

User and company name comments in Xcode projects

Question: I am wondering how you change the comments that Xcode puts in the top of each source file to set the proper username and company name instead of updating every file by hand if these macro fields are different from the default settings of Address Book. I am speaking about these source code lines: // Created by MyUserName on 8/19/10. // Copyright __MyCompanyName__ 2010. All rights reserved. Continue reading →

Cancel window closing operation in java app

Question: In my Java swing crossplatform project I have to ask the user if he/she really wants to quit from the desktop application before exit, so I have to handle the WindowClosing event. My problem is simple. I expected the DO_NOTHING_ON_CLOSE flag to prevent the form from closing. I didn’t thought the WindowClosing event will be fired even if the setDefaultCloseOperation was set to DO_NOTHING. When I even click on the NO button the window does close! Have you experienced it before and what have you done? Thank you in advance. I am attaching my code. Continue reading →

Strong 8345CI remote control for SlingBox

Question: I have a SlingBox Pro HD. I bought a Strong 3845 CI satellite and DVB-T receiver in Vienna I want to control and watch remotely from the States. So I opened the Setup Assistant and went through the device options and when I get to ‘Who Manufactured your Satelite Receiver’ I could not find my Strong receiver. I tried all kinds of options and still can not get it done. I heard that I needed a programmer who could create remote control codes in a binary file for the SlingBox. I have a home network with WiFi DSL router and a laptop. Continue reading →
