Time Left Counter

This script will give you a count down of Years, Months, Days and Hours left to a given date.

 

Enter a date as Month day, year

 

Click to see the days left

<script>
function cdtime( targetdate){

var currentTime=new Date()
var tdate=new Date(targetdate)
var timesup=false
var timediff=(tdate - currentTime)/1000
var oneHour=3600 //hour unit in seconds
var oneDay=86400 //day unit in seconds
var oneMonth=2630880 //month unit in seconds
var oneYear=31570560
var yearfield=Math.floor(timediff/oneYear)
timediff = timediff - (yearfield * oneYear)
var monthfield=Math.floor(timediff/oneMonth)
timediff = timediff - (monthfield * oneMonth)
var dayfield=Math.floor(timediff/oneDay)
timediff = timediff - (dayfield * oneDay)
var hourfield=Math.floor(timediff/oneHour)
if (currentTime >= tdate){
	var ret = "The time is up!"
}else{
	if (yearfield > 1){ret = yearfield + " Years " }else{ret = yearfield + " Year "}
	if (monthfield > 1){ret = ret + monthfield + " Months "}else{ret = ret + monthfield + " Month "}
	if (dayfield > 1){ret = ret + dayfield + " days and " }else{ret = ret + dayfield + " day and " }
	if (hourfield > 1){ret = ret + hourfield + " Hours left"}else{ret = ret + hourfield + " Hour left"}
}

return ret
}
</script>

To call it just place this code on your page.



document.write(cdtime("July 1, 2010"))

Dealing with Downloading files

Helpful tips for File Download

There are several ways to handle file download.
The best ways due to speed and Browser compatibility are third party upload/download products.
Two of the most popular are Persits ASPUpload and SA's Fileup.

These examples will show typical code associated with both.
For Persits:
To visit their Web Site Persits Software
Version 2 is a problem with some browsers - I suggest using version 3
on error resume next
Dim s_filename, s_filepath, s_fullpath
s_filename = Request.QueryString("file_name")
S_filepath = server.MapPath("sub_directory_name") & "\"
S_fullpath = filepath & filename
Set obj_Upload = Server.CreateObject("Persits.Upload")
if err = 0 then
  obj_Upload.SendBinary fullpath, True, "application/octet-stream", True ' (version 3)
  ' obj_Upload.SendBinary fullpath, True, "application/octet-stream" '(version 2)
else
  response.write(err.Description)
end if
if err then response.write("An Error has occurred - Please contact us - Error:" & err.Description)
set obj_Upload = nothing

For SA Fileup:
To visit their Web Site SoftArtisans
Dim s_filename, s_filepath, s_fullpath, oFS, oF
s_filename = Request.QueryString("file_name")
S_filepath = server.MapPath("sub_directory_name") & "\"
S_fullpath = filepath & filename
Response.Addheader "Content-Disposition", "Attachment; filename=" & filename
Response.ContentType = "application/pdf"
fullpath = filepath & filename
set oFS = Server.CreateObject("Scripting.FileSystemObject")
set oF = oFS.GetFile(fullpath)
Response.AddHeader "Content-Length", oF.Size
set oF = nothing
set oFS = nothing
Set download = Server.CreateObject("SoftArtisans.FileUp")
download.TransferFile fullpath
set download = nothing

Now if you don't have either of these or any other third party tools then we have two other ways to set your download.

Using simple script:
This works but it is slow to start with large files so your user may think your script is bad or that his browser died.
You also must use "application/octet-stream" as the mime type else the browser may open the file rather than download it.

ASP
 on error resume next
filename = Request.QueryString("filenm")
Dim s_filename, s_filepath, s_fullpath
s_filepath = server.MapPath("catalog") & "\"
s_fullpath = filepath & filename
set oFS = Server.CreateObject("Scripting.FileSystemObject")
Set oF = oFS.OpenTextFile( fullpath, 1, False )
If oFS.FileExists( fullpath ) Then
  Response.Addheader "Content-Disposition", "Attachment; filename=" & filename
  Response.ContentType = "application/octet-stream"
  While Not Bin.AtEndOfStream
    Response.BinaryWrite( ChrB( Asc( Bin.Read( 1 ) ) ) )
  Wend
Else
  Response.Redirect( "file_error.asp?fln=" & fullpath )
End If
Bin.Close
Set Bin = Nothing
set oFS = nothing

Simple download using .NET
For this one you must save the script as .aspx in order for it to work and your server must support .net
It is almost perfect in operation as an alternative to third party software.

Dim s_filename, s_fullpath
s_filename = Request.QueryString("file_name")
s_fullpath = Request.PhysicalApplicationPath & "catalog/" & filename
Response.Addheader("Content-Disposition", "Attachment; filename=" & s_filename )
Response.ContentType = "application/pdf"
Response.WriteFile (s_fullpath)

PHP

Remote Scripting

Remote Scripting


Many in the RS World are turning to the XML Parser from MicroSoft
Using XMLHTTP you can acomplish remote scripting but there are pit falls.
The biggest pitfall is calling a page in the same directory will crash the server.
There is nothing to install or download, the parser is supported by most browsers


JSRS:

This method uses an Iframe to accomplish similar functionality.

Other than this problem with the history bug in Netscape - JSRS works fine. Any browser that supports Ifames will work fine with JSRS and since the Iframe is now a standard I believe this is the better choice of the two.

For Compatibility with all browsers JSRS offers RSLite - This one uses image/cookie method to accomplish Remote Scripting.

Dealing with an Access database on the WEB

How to maintain an Access Database on the WEB

If you are setting up a Internet or Intranet site and really don't need to use SQL Server or Oracle as your database - Access may just do the trick.
The only problem is when you need to modify the database or import data.
The question becomes how do you do it.
You don't want to overwrite the database file because this can be a problem.
Should users be logged on at the time you decide to replace it you will run into trouble.

The best way is to use a remote access utility. There are a few on the market that serve this purpose but you might want to look into a product called Cute ASP Table Editor.

This one can be downloaded free from:    http://sourceforge.net/projects/cuteasp/

Placing Text on a Picture

Placing Text on a Picture

One method we can use is using a table with the picture as the background

 

We can set the background for the column
and place the text within the TD tag as normal
<td background="mars_lander.gif" width="231" height="265" align="center" nowrap>
<h1><font color="yellow">Is there Life on Mars?</font></h1></td>

Is there Life

on Mars?

 

Another method we can use is using position or layers

For this example We will use the div tag
<div class="div_set"><br><br>Is there Life<br>on Mars?</div>

For the Style we have the following:

<STYLE>
     .div_set {z-index:1; background-image: url(mars_lander.gif);
     font-size:34; font-weight:bold; text-Align:center;
     color: yellow; position:relative; width: 231; height:265;}
</STYLE>
 

 

Is there Life

on Mars?

In both cases to avoid repeating the image use background-repeat:no-repeat
