I have a classic ASP page, and I need to create a loop for each row on a table and then create an html document and save it to the hard drive, but I want to create a template so I just send the two variables to the template so I don't have to write the HTML document each time on the loop.
This is what I have so far:
SQL = "select Title, Article from [ASPTest].[dbo].[articles]"
set rs = conn.execute(SQL)
arrRecs = rs.GetRows
For row = 0 To UBound(arrRecs, 2) 'Rows
For col = 0 To UBound(arrRecs, 1) 'Columns
Response.Write rs.Fields(col).Name & " = " & arrRecs(col, row) & " "
dim fs,f
set fs=Server.CreateObject("Scripting.FileSystemObject")
set f=fs.CreateTextFile("C:\Users\User\Documents\ASP Pages\"+arrRecs(col, row)+".html",true)
f.write("<html><body><div>It kinda works</div></body></html>")
f.close
set f=nothing
set fs=nothing
Next
Response.Write "<br />"
Next
Is there a way to use a template that has 2 variable holders and send the article name and title to the template and then save it to the disk?
Thank you.
I think you could probably achieve what you want using a template stored as a text file, and the Replace function.
Your template should be a fully-formed html page, but with placeholder values for the title and article. The placeholders need to be unique, so something like [[[~~~Title~~~]]] or a similar sequence that will not occur in your actual titles, articles, or the template itself.
<html>
<head><title>[[[~~~Title~~~]]]</title></head>
<body>
<h1>[[[~~~Title~~~]]]</h1>
<div id="article">[[[~~~Article~~~]]]</div>
</body>
</html>
In your code, read the template from the file and store it in a variable. (So technically, you could just write it to a variable in the first place, but VBScript is bad at string concatenation... anyway.) Get your array of titles & articles and loop through it (though only once: I'm not sure why you're looping through both rows and columns in your attempt). For each row, make a copy of the template, replace the title placeholder with the current row's title, replace the article placeholder with the current row's article, and write the result to a file.
Dim template, t
Dim fso, file
Dim rs, conn, SQL
Dim records, row
SQL = "SELECT ID, Title, Article FROM [ASPTest].[dbo].[articles]"
'[...database stuff...]
records = rs.GetRows
'[...close database...]
Set fso = Server.CreateObject("Scripting.FileSystemObject")
Set file = fso.OpenTextFile("path/to/template.txt",1) '- 1 = For reading
template = file.ReadAll
file.Close
Set file = Nothing
For row = 0 to UBound(records,2)
t = template
t = Replace(t,"[[[~~~Title~~~]]]",records(1,row))
t = Replace(t,"[[[~~~Article~~~]]]",records(2,row))
Set file = fso.CreateTextFile("path/to/html/" & records(0,row) & ".html")
file.Write(t)
file.Close
Set file = Nothing
Next
Set fso = Nothing
Back in the day I created the KudzuASP template engine to solve this rather complex deficiency in Classic ASP. In KudzuASP you can have ASP code pages that have absolutely NO HTML in them.
KudzuASP is as small include file roughly under 1000 lines of code that turns your hosting ASP page into an event driven object used by the template engine.
In short you create an instance of the template engine, set some variables, install custom code objects, and invoke it after which the template engine reads your template and make callbacks to your ASP page when and where appropriate. It has a library system so you can load libraries of custom tags handlers/components via code or by tags placed in your HTML template.
One of the best features is that for those still under the Classic ASP umbrella it makes 100% separation of application code and logic from presentation possible. Coding Classic ASP pages using KudzuASP is much easier than without and because of the way ASP compiles pages the callbacks are "native" and very fast.
You can find it here KudzuASP where the project is still maintained.

So, as I figured out, when I have a form with enctype="multipart/form-data" and I upload a file, I can no longer access the object request. The following error is shown:
Cannot use the generic Request collection after calling BinaryRead.
After checking some resources, I stumpled upon a statement, which says: "This is by design". Well, okay, not here to judge about design-decisions.
To give you a quick overview, let me walk you through the code:
if request("todo") = "add" then
Set Form = New ASPForm
category = request("category")
title = request("title")
if len(Form("upload_file").FileName) > 0 then
filename = Form("upload_file").FileName
DestinationPath = Server.mapPath("personal/allrounder/dokumente/")
Form.Files.Save DestinationPath
end if
end if
Nothing too special here so far. Later however, when I try to access my request object, the error mentioned above occures:
<% if request("todo") = "new" then %>
...
My question now, how to get rid of it or fix this. I don't want to open the upload in a popup if there is another way around. This is the only solution I could think off.
Perfectly would be an object, which checks Form and request. Alternatively maybe a check at the top of the file, which object I have to use?
Thanks for any suggestions.
There used to be a very popular ASP class/component that solved ASP file uploads. The site for that component has been taken down, but the code is mirrored here:
https://github.com/romuloalves/free-asp-upload
You can include this ASP page on your own page, and on your page instantiate the class to get access to the files in your form, but also to the form variables. Here is a piece of example code (Upload.Form accesses the form fields):
Dim uploadsDir : uploadsDir = server.mapPath(".") ' whatever you want
Dim Upload, ks, fileKey, mailto
Set Upload = New FreeASPUpload
call Upload.Save(uploadsDir)
ks = Upload.UploadedFiles.keys
for each fileKey in ks
Response.write(fileKey & " : " & Upload.UploadedFiles(fileKey).FileName & "<br/>")
next
mailto = Upload.form("mailTo")
Set Upload = Nothing
If you want to stick to your own implementation, you can probably figure out how to get to the form variables in a multipart/form-data encoded data stream by having a look at the code they use to do so.
I have tow pages, first one for displaying the data in the text file and the other one is to store the data. I want to save a site in the text file but when i display the data will be just text and I can't click it as a link. The code I post is when I write to a file in display page.
Try
Dim fs As String
fs = Server.MapPath("Footer.txt")
lblsplittext.Text = ""
Dim filestream As StreamReader
filestream = New IO.StreamReader(fs)
Dim readcontents As String = filestream.ReadToEnd()
Dim textdelimiter As String = "#"
Dim splitout = Split(readcontents, textdelimiter)
Dim i As Integer
For i = 0 To UBound(splitout)
lblsplittext.Text &= splitout(i) & "<br>"
Next
filestream.Close()
Catch ex As Exception
Dim str As String
str = ex.Message
End Try
If you have a different suggestion about how to read from a file or database (it doesnt matter from where for now) just keep in mine when i display them i just need to have hyperlinks among my text... Or can I write to html file instead of text file if so what is the difference i need to make to write to html. I really really need help here and i have done many searches but i found nothing.
Thanks in advance.
There are a number of ways you could do this. One would be to use a series of dynamically-added Label controls. Your Hyperlink control could simply be inserted between one Label control and the next.
Do you intend to retrieve information from your series of labels on postback? (It would be redundant to do that, since you already know what the information is, but just in case.) Using multiple controls would make that more complicated. You could try one or more Literal controls, created dynamically and added as child controls to a Panel control. Again, the Hyperlink control would be added at whatever time you need it.
I am trying to create an automatically generate a table of contents page for a directory with a variable number of HTML files. I have created this:
<ul>
<%
dim fs,fo,x
set fs=Server.CreateObject("Scripting.FileSystemObject")
set fo=fs.GetFolder("c:\test\html\")
for each x in fo.files
newName=Split(x.Name, ".")
'Print the name of all files in the test folder
for each y in newName
Response.write("<li><a href='" & x.Name & "'>" & y & "</a></li>")
next
next
set fo=nothing
set fs=nothing
%>
</ul>
The problem here is that the links are generated using the file name, so I get things like "introduction" instead of "Introduction to This Topic." The html > head > title element in each HTML document is the link text I want to use. Is there a way I can extract it from each file?
(I am open to a solution that doesn't use ASP. I created this simply because it was what I had available to me. I'm not very familiar with ASP or its capabilities, so there might be a more efficient way to tackle this problem.)
There's no saying that all of the files in a folder are actually used and are part of a site, or how these files relate in a sitemap structure. It's better to approach this from a crawler on the outside than a file-system on the inside.
There are various sitemap generating services on the web that you can use. You can grab the results and edit them to suit your needs and post them as your own directory.
I am building a page for produce name "product.aspx"
I have display some products in this page with hyperlink.
Now I want, when I click my product (such as pen) then it automatically makes an html page name pen.html with some information.
When I click clock then it automatically makes an html page name clock.html with some information.
How can I do this?
I am using asp.net C# 3.5.
You can use a Literal to crete your html page
in frontend ypu can add Literal
so in backend code you can create a html page by adding text to the literal
eg.
var productdata = datasource;
ltrProduct.text ="<head><title>"+productdata.title+"</title></head><body></body></html>";
Rather than actually creating a physical file for these products, its best to have a Web Form called something like "Product.aspx" which you pass a querystring to like:
/Product.aspx?product=Pen
This can then be URL Rewritten to something like:
/Product/Pen.aspx
You can then use this query string to return data like:
Dim cmd as new sqlcommand("SELECT Name, Price FROM Products WHERE FileName=#FileName", Conn)
cmd.CommandType = CommandType.StoredProcedure
cmd.parameters.AddWithValue("#FileName", Request.QueryString("product"))
I mean, like php'h include...
something like
my_file_to_be_included = "include_me.asp"
-- >
for what I've seen so far, there are a couple of alternatives, but every one of them has some sort of shortcoming...
what I'm trying to figure out is how to make a flexible template system... without having to statically include the whole thing in a single file with a loooooong case statement...
here there are a couple of links
a solution using FileSysmemObject, just lets you include static pages
idem
yet another one
same thing from adobe
this approach uses Server.Execute
but it has some shortcomings I'd like to avoid... seems like (haven't tried yet) Server.Execute code runs in another context, so you can't use it to load a functions your are planning to use in the caller code... nasty...
same thing
I think this one is the same
this looks promising!!!
I'm not sure about it (couldn't test it yet) but it seems like this one dinamycally handles the page to a SSDI component...
any idea???
No you can't do a dyanmic include, period.
Your best shot at this is a server.execute and passing whatever state it needs via a Session variable:-
Session("callParams") = BuildMyParams() 'Creates some sort of string
Server.Execute(my_file_to_be_included)
Session.Contents.Remove("callParams")

Sure you can do REAL classic asp dynamic includes. I wrote this a while back and it has opened up Classic ASP for me in a whole new way. It will do exactly what you are after, even though people seem to think it isn't possible!
Any problems just let me know.
I'm a bit rusty on classic ASP, but I'm pretty sure you can use the Server.Execute method to read in another asp page, and then carry on executing the calling page. 15Seconds had some basic stuff about it - it takes me back ...
I am building a web site where it would have been convenient to be able to use dynamic includes. The site is all ajax (no page reloads at all) and while the pure-data JSON-returning calls didn't need it, all the different html content for each different application sub-part (window/pane/area/form etc) seems best to me to be in different files.
My initial idea was to have the ajax call be back to the "central hub" main file (that kicks the application off in the first place), which would then know which sub-file to include. Simply including all the files was not workable after I realized that each call for some possibly tiny piece would have to parse all the ASP code for the entire site! And using the Execute method was not good, both in terms of speed and maintenance.
I solved the problem by making the supposed "child" pages the main pages, and including the "central hub" file in each one. Basically, it's a javascript round-trip include.
This is less costly than it seems since the whole idea of a web page is that the server responds to client requests for "the next page" all the time. The content that is being requested is defined in scope by the page being called.
The only drawback to this is that the "web pieces" of the application have to live partly split apart: most of their content in a real named .asp file, but enough of their structure and relationship defined in the main .asp file (so that, for example, a menu item in one web piece knows the name to use to call or load another web piece and how that loading should be done). In a way, though, this is still an advantage over a traditional site where each page has to know how to load every other page. Now, I can do stuff like "load this part (whether it's a whole page or otherwise) the way it wants to be loaded".
I also set it up so each part can have its own javascript and css (if only that part needs those things). Then, those files are included dynamically through javascript only the first time that part is loaded. Then if the part is loaded repeatedly it won't incur an extra overhead.
Just as an additional note. I was getting weird ASCII characters at the top of the pages that were using dynamic includes so I found that using an ADODB.Stream object to read the include file eliminated this issue.
So my updated code for the getMappedFileAsString function is as follows
Function getMappedFileAsString(byVal strFilename)
Dim fso
Set fso = CreateObject("ADODB.Stream")
fso.CharSet = "utf-8"
fso.Open
fso.LoadFromFile(Server.MapPath(strFilename))
getMappedFileAsString = fso.ReadText()
'Response.write(getMappedFileAsString)
'Response.End
Set fso = Nothing
End Function
