In JSP Why Expression tag can not take the semicolon at end of statement -


expression element in jsp <%= … %> 1 java expression ex: 

 index.jsp  ----------  welcome jsp scripting elements    <%! int num1=10;       int num2=20;       int add;    %>   <% add=num1+num2 %>     addition is<%= add %> <@!-- expression tag -->

from the java server programming black book:

an expression tag contains scripting language expression evaluated, converted string, , inserted expression appears in jsp file. because the value of expression converted string, can use expression within text in jsp file.

like:

    <%= someexpression %>      <%= (new java.util.date()).tolocalestring() %>

you cannot use semicolon end expression.

in example code

<%= add %>

means

out.print(add);

if have add semicolon before close tag

then invalid

out.print(add;);

it shows error.

know more jsp scripting tags

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
