tcl - Condition based on environment variable existance -

Is it the right to use the following condition based on environment variables? Or better way?

Example: 

  # Both environment variables must exist if {expr [eval {info exists env (VARIABLE_1)}] & amp; [Eval {info exists env (VARIABLE_2)}]} {# true: do something} second {# false: separate something}

c# - Highlight all words containing a letter in a richtextbox -

For example, you can not Galaxy Nexus (Nexus 3), Galaxy S, on the HTC One.

Do you know of any solutions or possible solutions to the problem? Thanks! --- Update - - This activity declaration is: & amp; Activity Activity:...

I am trying to add a JTabbedPane to a panel, as well as for control I am using Migrates with the following buttons.
