Android - Switching Activities with a Tab Layout
This post is based on the Tab Layout tutorial on the Android developers site, with some modifications. I wanted to get rid of the icons (they take up too much screen real estate), and modify the fonts on the tabs. First, create a new Android project, with an Activity called TabWidget. Then, create two additional Activities called TabOne and TabTwo. Throw a simple TextView on each one with a message identifying the tab, like this: public class TabTwo extends Activity { @Override public void onCreate(Bundle ......

BizTalk - Stopping TA1 generation in EDI applications
When receiving EDI messages in BizTalk, you have the option of sending an Interchange Acknowledgment (TA1) when a file is received. This is configured in the X12 Fallback Settings in BT 2010, or in EDI Global Properties in previous versions. However, even if you have this disabled, if your inbound file has the ISA14 field (Acknowledgement Requested) set to 1, then a TA1 will be created. It will then be suspended, since BT doesn't know what to do with the message. To get around this, you have two ......

Simply create another activity that implements the onCreateOptionsMenu() and onOptionsItemSelected() methods, like this: public class MasterActivity extends Activity { @Override public boolean onCreateOptionsMenu(Menu menu) { ... whatever ... } @Override public boolean onOptionsItemSelected(MenuItem item) { ... whatever ... } } Then have all of ......
