main.c:99: error: ‘LangParser_decl_return’ undeclared (first use in this function)

Page in ANTLR3C API : http://antlr.org/api/C/index.html

Something must be changed to fit your project:

1. All variables containing /.*Lang.*/, change "Lang" to "JavaScript" or your language which your grammar described. (I wrote a JavaScript.g file to describe JavaScript Language Grammar.)

2. Change "LangParser_decl_return" to "JavaScriptParser_program_return", where "JavaScript" is what I said ablow, and where "program" is the first token you define below the "option" token, in Grammar file (JavaScript.g).
ps: You may want to change all "decl" to "program", because "decl" only in file "ANTLR_Examples.zip/C/treeparser/Lang.g"

Bash: checking if a variable is a number

[code]

# v=1

# [ $v -eq $v ]

# echo $?

0

# v=a

# [ $v -eq $v ]

# echo $?

2

[/code]

Note: "-eq" compares number, but not string.

bug

Windows 7下IE8即使导入了https证书仍然显示“证书错误”

现象：
Windows XP系统下，使用IE6/IE7/IE8，登录Web管理系统的时候提示证书错误，然后导入证书（自动选择证书存储区），重启IE（或者重启OS），再次登录Web管理系统，则没有提示证书错误。
Windows 7系统下，使用IE8，登录Web管理系统的时候提示证书不被信任，然后导入证书，重启IE（自动选择证书存储区），再次登录Web管理系统，地址栏里面仍然显示"证书错误"。
在证书管理器中比较这两个OS下的https证书存储区发现是不同的。

解决：
Windows 7系统下，使用IE8导入证书的时候请选择存储区为"受信任的根证书办法机构"，否则自动选择的存储区。

IE gives warning when redirect from HTTPS to HTTP

If you use header() method provided by PHP, to redirect from HTTPS to HTTP,
IE will give out a warning, but if you use the code below above othe PHP code, no warning will show.
// =========================================================
<?php                                                                                                                                                                                                     
if($_SERVER['HTTPS'] == "on") {
    $redirect = "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    echo "<meta http-equiv=\"refresh\" content=\"0; url=$redirect\">";
    exit();
}
?>
// ==========================================================
The tag "<meta>" will refresh the web page and jump/redirect to another web page.
