Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Web: List Request Variables

    This A5W page code will return the values for all of the Request Variables for a given page displayed in the browser. As written it will show the vars in the browser. It is also useful to modify this code to save the variable "st" to a text by replacing the line ?st with save_to_file(st,"c:\myvars.txt"). And then you can call it from the page you want to evaluate.

    As in:
    ....html code...
    a5w_include("show_request_vars.a5w")
    ... rest of my page


    Code:
    <html>
<head>
<meta name="generator" content="Alpha Five HTML Editor Version 9 Build 2095-3264">
<title></title>
</head>
<body>
<%a5 
dim st as c = ""
st = st + "<h1>Request Variables</h1>"

st = st + "<h2>Request.ApplicationRoot</h2>" 			+  Request.ApplicationRoot
st = st + "<h2>Request.Browser.CookiesEnabled</h2>" 	+  Request.Browser.CookiesEnabled
st = st + "<h2>Request.ContentType</h2>" 				+  Request.ContentType
st = st + "<h2>Request.Headers</h2>" 					+  Request.Headers
st = st + "<h2>Request.Body</h2>" 						+  Request.Body
st = st + "<h2>Request.HTTP_Request</h2>"				+  Request.HTTP_Request
st = st + "<h2>Request.Host</h2>" 						+  Request.Host
st = st + "<h2>Request.Query_String</h2>" 				+  Request.Query_String
st = st + "<h2>Request.Raw</h2>" 						+  Request.Raw
st = st + "<h2>Request.Remote_Addr</h2>" 				+  Request.Remote_Addr
st = st + "<h2>Request.Request_Method</h2>" 			+  Request.Request_Method
st = st + "<h2>Request.Request_URI</h2>" 				+  Request.Request_URI
st = st + "<h2>Request.Script_Name</h2>" 				+  Request.Script_Name
st = st + "<h2>Request.Server_Protocol</h2>" 			+  Request.Server_Protocol

'OPTIONAL VARS
st = st + "<h1>Optional Request Variables</h1>"

if eval_valid("Request.Accept")
	st = st + "<h2>Request.Accept</h2>" 			+  Request.Accept
end if
if eval_valid("Request.Accept_Encoding")
	st = st + "<h2>Request.Accept_Encoding</h2>" 	+  Request.Accept_Encoding
end if
if eval_valid("Request.Accept_Language")
	st = st + "<h2>Request.Accept_Language</h2>" 	+  Request.Accept_Language
end if
if eval_valid("Request.Connection")
	st = st + "<h2>Request.Connection</h2>" 		+  Request.Connection
end if
if eval_valid("Request.Cookie")
	st = st + "<h2>Request.Cookie</h2>" 			+  Request.Cookie
end if
if eval_valid("Request.Referer")
	st = st + "<h2>Request.Referer</h2>" 			+  Request.Referer
end if
if eval_valid("Request.User_Agent")
	st = st + "<h2>Request.User_Agent</h2>" 		+  Request.User_Agent
end if

?st

    Re: Web: List Request Variables

    The problem with this code is that it is hard-coded to only list specific properties of Request. It covers the common ones, but will not get everything. If you don't want to use a5w_info(), the code below will generate a listing of all of the properties of Request.

    Also, if using Steve's code as an include as he suggested could be done, beware of the included file being a complete HTML page itself. This will cause display problems in many browsers because it generates invalid HTML in the containing page.

    Code:
    <%a5
dim RequestVars as c
RequestVars = properties_enum(Request)
? "<table border=\"1\">" + crlf()
? "	<tr><td colspan=\"2\"><h2>Request</h2></td></tr>" + crlf()
? "	<tr><th>Variable</th><th>Value</th></tr>" + crlf()
for each var in RequestVars
	dim vartype as c
	vartype = typeof(eval("Request." + var))
	if (vartype = "P")
		? "	<tr><td>Request." + var + "</td><td>" + strtran(*html_escape(properties_enum(eval("Request." + var))),crlf(),"<br />"+crlf()) + "</td></tr>"
	else if (vartype = "F")
		? "	<tr><td>Request." + var + "()</td><td></td></tr>"
	else
		? "	<tr><td>Request." + var + "</td><td>" + strtran(""+*html_escape(""+eval("Request." + var)),crlf(),"<br />"+crlf()) + "</td></tr>"
	end if
next var
? "</table>"
%>

      Re: Web: List Request Variables

      Thanks Lenny, I was trying to figure out how to enumerate request.variables, but couldn't figure it out. I knew there must be more variables than listed in the Help or A5Info.

      Note - I ran Lenny's code and there still isn't a variable with the full URL, so you are stuck with a method similar to what I posted earlier.
