I am converting a classic ASP page to ASP.NET Vb . I get a line of code Where reading value form cookies .Below is the line of code where value is checking . My problem is that how can i convert this line of code in ASP.NET VB . I am doing inline code for conversion
<%if request.Cookies("parker")("id") <> "" then%><input name="agreement_acceptance_box" type="checkbox" value="yes"><%end if%>
Thanks for your answer . Its really very important for me
I think the problem is to read an array from the cookie? You don't provide much 'context', so I assume you have a Request object (it should be somewhere around ;-)):
If Not Request.Cookies("parker") Is Nothing AndAlso Not Request.Cookies("parker")("id") Is Nothing Then
...

I write the following piece of codes :
rst.Open(strSQL & Request.QueryString("C-PLACE")), conn, 0, 1
But got the following error. However, if the querystring is in English or just number, no error will pop out. Any guru can help please ?
Microsoft OLE DB Provider for ODBC Drivers error '80040e10'
[Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 2.
/deliverable/GetMemberTest.asp, line 19
It's going to either be passing an encoding variable to the server, or in the case of your error, its saying "too few parameters". In this case, the parameter is "C-PLACE" and its suppose to be passed to your asp script from the previous page's link, something like:
/deliverable/GetMemberTest.asp?C-PLACE=THECPLACE
https://www.w3schools.com/asp/coll_querystring.asp
(citation about query strings)
or something like that .. obviously its not actually "THECPLACE", but just saying a QueryString("VARIABLENAME") looks to the URL of the previous page to pass the parameter to the script, so that error message should of done something to add a ? mark = C-PLACE= to something, and we aren't seeing that. So something on the previous page that was suppose to add this when they click a submit button didn't do it's job, or the script is just getting run on its own without the proper previous page's work being done to prepare it to execute properly on the following page.
It will also be of note that these types of things are easily hacked through sql script injection, so if you aren't validating your url first, someone could use some code to escape out of your sql and add their own code, such as one to drop your tables ..., so make sure you validate the variable FIRST instead of dumping it straight into your code. I can give some guidance into that later, but first lets figure out your problem.
(side note - can i request strSQL from you? Can you put this line in before that line:
<%
response.write("strSQL is " & StrSQL & "<BR>")
%>
All this code does is display what is stored in the StrSQL variable, see if we can figure out what is going on here. Also take note that your error message indicated that it expected 2 parameters, so we are missing 2 for this script to run properly.
EDIT - try this encoding:
<%
Response.CodePage=65001
Response.Charset="UTF-8"
Response.ContentType = "text/html"
%>
Try this strSQL, you didn't need the Response.Write and on C-PLACE you want to use '' instead of "" because the "" will exit you out of the SQL statement. Try this, and let me know how it works, but I still think we are going to need another parameter supplied to it, unless its getting one from the string and then it isn't actually counting the one supplied from the url perhaps.
<%
strSQL="SELECT * FROM DetailMemberInfo
WHERE C-PLACE=" & strSQL & Request.QueryString('C-PLACE'))"
%>
I have one problem ... I try two days to get QueryString which contains characters which are URL encoded like this %8B%83%94%837n . All that characters are from here http://www.tutorialspoint.com/html/html_url_encoding.htm .
Now when I try to get the QueryString from %8B%83%94%837n I get only the last characters 7n. They are not some special characters which must be encoded. This is work in Asp classic vbscript.
Is anyone has solution for this I would be thankful if help me. Any other solution of this problem is acceptable.
Many thanks :)
MyVar = server.htmldecode(YourQueryString)
MyVar = server.htmlencode(YourQueryString)
Assume I have a file that contains :
<%
Response.write("<my_tag>value</my_tag>")
%>
If I get it as an ordinary XML file, I get an error telling me that the XML have not the right format because it begin by "<%". How can I read this XML dynamically generated ?
Edit:
In fact, it was an illusion. The Server.Execute method just print the other file. What can I do ? How could I put the result of an ASP page in a string that I could read by loadXML method ? Or how could I just process the file before loading it ?
Give it a file extension that ASP will know to process, or tell ASP to process the file extension you're using. The server has to know to process the file and give you the dynamic result. It doesn't treat every file served as a classic ASP file, you have to tell it what to treat the file as if you're using a non-standard extension for ASP. You can do this by mapping the classic ASP handler to the file type you're trying to HTTP GET.
Use an .asp extension and set the Content Type:
<%
Response.CharSet = "utf-8"
Response.Buffer = True
Response.ContentType="text/xml"
Response.Write "<?xml version=""1.0"" encoding=""utf-8""?>"
Response.Write "<my_tag>value</my_tag>"
Response.Flush
%>
You might take a look here: http://www.w3.org/TR/REC-xml/
We have a asp:DropDownList that we populate server side with
ddlBranch.Items.Add(new ListItem("TEST","This is a's test"));
When this is compiled and run under .NET 3.5 we see the text "This is a's test"
However when this is compiled and run under .NET 4.0 we see the text "This is a's test"
We have added the following to our web.config and there was no change.
<pages controlRenderingCompatibilityVersion="3.5" />
For the time being we have dropped back to .NET 3.5 however we would like to know if there is a way to work around this or if this is a known rendering issue or is by design.
TIA

Hi All
Thanks for the responses and they led me to look deeper into the code looking for an Encode somewhere. It turns out there that was a:
Server.HtmlEncode(input)
being performed on all controls in a base page class.
Now what I thought was a problem really turns out to be a case of RTFM on my part
From http://www.asp.net/learn/whitepapers/aspnet4/breaking-changes
HtmlEncode and UrlEncode Now Encode Single Quotation Marks
In ASP.NET 4, the HtmlEncode and UrlEncode methods of the HttpUtility and >HttpServerUtility classes have been updated to encode the single quotation mark character >(') as follows:
The HtmlEncode method encodes instances of the single quotation mark as ' .
The UrlEncode method encodes instances of the single quotation mark as %27.
So when I was using .NET3.5 my single quote ( ' ) was being ignored by the HtmlEncode but when switching to .NET 4.0 it was not being ignored by HtmlEncode.
Thanks again for all the responses and work that people put in to this question.
Regards
AJ
When you get the value back you could just HTMLDecode the selected value.
ie. Server.HtmlDecode(ddlBranch.SelectedValue)
Why do you believe this is a problem? ' renders as an apostrophe, and when posted will turn into an apostrophe if that value is selected.
A client of mine is using a Classic ASP script to process a form from a third-party payment processor (this is the last step in a credit-card-transaction sequence that starts at the client's website, goes to the third-party site, and then returns to the client's site).
The client is in Austria and when one of the fields includes an 8-bit character (e.g., when the field value is Österreich), the Ö is simply dropped when I retrieve the value of the field in the standard way; e.g.:
fieldval = Request.Form("country")
If fieldval = "sterreich" Then
' Code here will execute
End If
The literal value that the third-party page is POSTing is %D6sterreich, which I think suggests that the POST is being encoded in UTF-8.
The POST request has the following possibly-relevant headers:
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Content-Type: application/x-www-form-urlencoded
I'm by no means a character-encoding expert and this is the first time I've really done anything with Classic ASP, so I'm kind of flummoxed.
From some Googling and searching SO, I've added the following to the page that processes the POST:
<%# Codepage=65001 %>
<%
Response.CharSet = "UTF-8"
Response.Codepage = 65001
%>
But it doesn't make any difference -- I still lose that initial 8-bit character. Is there something really simple that I'm just not aware of?
Try adding the following to the top of the page:
<%
Response.CharSet = "utf-8"
Session.CodePage = 65001
%>
Turns out I was going the wrong direction with this. The ASP file in question was itself encoded in UTF-8, which was implicitly setting Response.CodePage to 65001 -- in other words, explicitly adding a CODEPAGE directive made no difference -- and in fact the UTF-8 encoding was the source of the problem.
When I re-encoded the file to Windows-1252, the problem disappeared. I'm pretty ignorant of character encodings in general, but I think in retrospect the %D6 in the POST should have been my clue -- if I'm starting to understand things rightly, the single byte 0xD6 is not a valid UTF-8 character. Maybe someone more familiar with these things could confirm or deny this.
What about using the Ascii Character 0 in the query string, encoded as (%00), can I retrieve the whole value without terminating by Ascii 0?
http://localhost/Test_Authentication.asp?token=%13%23%02%00%01%01%00%01%01%05%02%02%03%00%02%02%0A%0A%0A%0A%0A%0A048
Response.CharSet = "utf-8";
Session.CodePage=65001;
var strToken = (Request.QueryString("token").Count > 0)?Request.QueryString("token")(1):"";
#Ben Dunlap: Try this at the top of the page --
<%#LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
Update
If you do a Response.Write Request.Form("country"), what does it display?
The 2 simple steps I used were:
add at the top of EVERY asp file:
Response.CharSet = "utf-8"
Response.CodePage = 65001
save every ASP text file in "ANSI" encoding (NOT utf-8!) - this option is usually found in the "Save" window of advanced text editors
If you save in utf-8 encoding or if you don't add the two line specified at the top of your code, this will never work as you intended.
My issue was similar (but quite strange) and adding the following two lines on all my pages has corrected it. Thanks so much for this.
Response.CharSet = "UTF-8"
Response.Codepage = 65001
But, to explain, here is the exact issue I had. Folks were entering Spanish characters on my ASP entry page and the results were very weird. For example" "Peña" was entered. The ASP page would display this, as entered, but what ended up in the database was displayed back as "Pe?a". This would have been sort of ok, except the hex actually stored in the database was 0x50653F6100. Notice the extra "00". Somehow the database stored value had an extra NULL at the end. So, when I later retrieved the data the screens went a little bonkers when the "00" [null] was hit and the displayed data essentially stopped after this data.
In any case adding the two lines seems to have fixed the issue and the "ñ" is stored in the database as it should be.
