Flex: Disable button in Togglebuttonbar

say, you defined your toggle button bar as below

<mx:ToggleButtonBar id="tbbModule" itemClick="tbbModule_Click(event)">
          <mx:Array>
          <mx:String>Home</mx:String>
          <mx:String>Module 1</mx:String>
          <mx:String>Module 2</mx:String>
          </mx:Array>
      </mx:ToggleButtonBar>

If you want to disable the first button, then


mx.controls.Button(tbbModule.getChildAt(0)).enabled =false;

Oracle: Regular expression to extract text from rtf string

After few trial and errors, figured out a way to extract text from rtf string format.

with rtf as ( select
'{\rtf1\ansi\deff0{\fonttbl{\f0\fnil\fcharset0 MS Sans Serif;}{\f1\fswiss\fcharset0 Arial;}{\f2\froman\fcharset0 Times New Roman;}}
{\colortbl ;\red0\green0\blue255;}
\viewkind4\uc1\pard\lang1033\f0\fs17 This is first line of rtf string with 01/02/1950 and some $10.20 with +ive sign
\par
\par e-mail second line rtf@rtf.com
\par \pard\sb100\sa100\cf1\lang1036\f1\fs24 Yes, Third line of rtf. \cf0\f2
\par \f1\fs20 some text \f2\fs24
\par \f1\fs20 123 456 abc 7890\f2\fs24
\par \pard\lang1033\f0\fs17
\par }' str from dual)
select str, regexp_replace(str, '({\\)(.*)(})|(\\[^ ]*)|(})') from rtf;

Here is the break down of Regular expression. It has 3 parts
({\\)(.*)(}) | (\\[^ ]*) | (})

Replace

1) Anything that starts with {\ followed by any any character(s) and ends with }

or

2) Any thing that starts with \ and not followed by a space

or

3) Replace the last }

Flex: Workspace in use or cannot be created

I have seen this annoying message more often in Flex Builder 3. It looks like the locks are not properly released when you quit Flex Builder.

If you get this error, You have 2 options

Option 1

1. Go to Task Manager
2. Kill FlexBuilder.exe
3. Kill Javaaw.exe

Option 2
Restart your pc

Either option will resolve this for you.

Data pump: Import multiple dump files

If the size of the dump file is large, usually they will be split into smaller chunks for easier ftp upload/download.

If you are trying to import a dump file that is split into many chunks, then you need to modify the DUMPFILE paratermeter to include %U

If the dump files are named EXP_PROD_1.dmp, EXP_PROD_2.dmp etc , then

DUMPFILE=EXP_PROD_%U.DMP
