How to validate Google Recaptcha 2.0 server side in ASP Classic? - asp-classic
I need help to implement the answer Google Recaptcha 2.0.
I've tried a few ways to recover the response after sending the form but not consigui get the answer True.
Follows the example I'm trying:
<%#LANGUAGE=VBSCRIPT%>
<%
Option Explicit
%>
<html>
<head>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
</head>
<body>
<%
If Request.ServerVariables("REQUEST_METHOD") = "POST" Then
Dim recaptcha_secret, sendstring, objXML
' Secret key
recaptcha_secret = "xxxxxxxxxxsec"
sendstring = "https://www.google.com/recaptcha/api/siteverify?secret=" & recaptcha_secret & "&response=" & Request.form("g-recaptcha-response")
Set objXML = Server.CreateObject("MSXML2.ServerXMLHTTP")
objXML.Open "GET", sendstring, False
objXML.Send
Response.write "<br><h3>Response: " & objXML.responseText & "</h3><br>"
Set objXML = Nothing
END If
%>
<form method="post" action="">
<!-- Site key -->
<div class="g-recaptcha" data-sitekey="xxxxxxxxxx"></div>
<br />
<input type="submit" value="Try">
</form>
</body>
</html>
How do I implement a way to check that Recaptcha were marked?
finally found it after so many search i found it
first i use this asp class https://github.com/zhennanzhuce/js/blob/master/js/ueditor/1.4.3/asp/ASPJson.class.asp
then to validate the response i use this
result = (objXML.responseText)
Set oJSON = New aspJSON
oJSON.loadJSON(result)
Set objXML = Nothing
success = oJSON.data("success")
if success = "True" then
action = "go to next page"
else
action = ""
end if
now the used code is :
<%#LANGUAGE=VBSCRIPT%>
<%
Option Explicit
%>
<html>
<head>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
</head>
<body>
<!-- #include file="aspJSON.asp"-->
<%
If Request.ServerVariables("REQUEST_METHOD") = "POST" Then
Dim recaptcha_secret, sendstring, objXML
' Secret key
recaptcha_secret = "XXXCCCXXXX"
sendstring = "https://www.google.com/recaptcha/api/siteverify?onload=onloadCallback&render=explicit&secret=" & recaptcha_secret & "&response=" & Request.form("g-recaptcha-response")
Set objXML = Server.CreateObject("MSXML2.ServerXMLHTTP")
objXML.Open "GET", sendstring, False
objXML.Send
dim result, oJSON, success, action, errorCapatcha, errorMsg
result = (objXML.responseText)
Set oJSON = New aspJSON
oJSON.loadJSON(result)
Set objXML = Nothing
success = oJSON.data("success")
if success = "True" then
action = "go to next page"
else
action = "do nothing"
end if
END If
%>
<form method="post" action="">
<!-- Site key -->
<div class="g-recaptcha" data-sitekey="XXXXXXXXX"></div>
<br />
<input type="submit" value="Try">
</form>
</body>
Many Thanks to Lankymart, Leonardo Duarte
First download json.asp https://github.com/tugrul/aspjson
insert in page
<script language="javascript" runat="server" src="json2.asp"></script>
in return do so
If success(objXML.responseText) = True Then
Response.write "success"
Elseif success(objXML.responseText) = False Then
Response.write "failure"
End If
call the function to get the json
Function success(result)
Set motor = JSON.parse(result)
success = motor.success
Set motor = Nothing
End Function
There is a better way and stand alone captcha for ASP instead google captcha. You don't need to add JSON function.
Here is the code:
On your submit page, add:
Type the number bellow:<br>
<input type=text name="captchacode" value="" size=5 maxlength=5><br/>
<img id="imgCaptcha" src="captcha.asp" /><br />
Refresh<br/>
<script language="Javascript">
function RefreshImage(valImageId) {
var objImage = document.images[valImageId];
if (objImage == undefined) {
return;
}
var now = new Date();
objImage.src = objImage.src.split('?')[0] + '?x=' + now.toUTCString();
}
</script>
Insert the function bellow to your asp file:
'*******************************************************
function TestCaptcha(byval valSession, byval valCaptcha)
'*******************************************************
dim tmpSession
valSession = Trim(valSession)
valCaptcha = Trim(valCaptcha)
if (valSession = vbNullString) or (valCaptcha = vbNullString) then
TestCaptcha = false
else
tmpSession = valSession
valSession = Trim(Session(valSession))
Session(tmpSession) = vbNullString
if valSession = vbNullString then
TestCaptcha = false
else
valCaptcha = Replace(valCaptcha,"i","I")
if StrComp(valSession,valCaptcha,1) = 0 then
TestCaptcha = true
else
TestCaptcha = false
end if
end if
end if
end function
Save the code bellow to captcha.asp:
<%#LANGUAGE="VBSCRIPT"%>

Argument 'expression' cannot be converted to type 'DBNull'
I have an app by vb for taking a list of doneators in Dvg and have about 17 forum and local mssql db and using if not is dbnull expression and by pressing the button some calculation happened and the answer appears in labels on the fourm.. But A strange problem happened when I run this app by the visual studio 2017 it run perfectly and there is no error.. But when converting it to exe file and setup it the following error appear when pressing this button " Argument 'expression' cannot be converted to type 'DBNull' " although it's not appear when run it with visual studio.. What could the problem be..? here is the code but i don't think the problem in it because it works fine in visual studio its long code so i will put a part of it and the rest is repeated for 12 months and 10 yearsthis is pic of the error If Form1.ComboBox1.Text = "2018" Then ' total kfalat If TextBox1.Text = "1" Then Form5.total.Text = Form1.Table1DataGridView.Rows.Count - 1 Dim HoN As Integer = 0

How to check if radiobutton in a row is unchecked

You can do it in a very shorter way using LInQ Extension .Any(): lblError.Visible = Not arrRad.Any(Function(rb) rb.Ckecked)

create multiple buttons from table in lua ( Corona sdk )
I have a table which looks like this:
table =
{
{
id = 1,
name = 'john',
png = 'john.png',
descr = "..."
},
{
id = 2,
name = 'sam',
png = "sam.png",
descr = "..."
}
...
}
What function could I use to display each picture like this and make them buttons
so that when I click on their image I can open their info.
This is where I am stuck:
local buttons = display.newGroup()
local xpos = -20
local ypos = 0
local e = -1
function addpicture ()
for i=1, #table do
xpos = (xpos + 100) % 300
e = e + 1
ypos = math.modf((e)*1/3) * 100 + 100
local c = display.newImage( table[i].name, system.TemporaryDirectory, xpos, ypos)
c:scale( 0.4, 0.4 )
c.name = table[i].tvname
buttons:insert(c)
end
end
function buttons:touch( event )
if event.phase == "began" then
print(self, event.id)
end
end
buttons:addEventListener('touch', buttons)
addpicture()
How can I recognize which image is touched in order to go back to the persons info?
I solved my problem by adding the listener inside of the loop like this:
function addpicture ()
for i=1, #table do
xpos = (xpos + 100) % 300
e = e + 1
ypos = math.modf((e)*1/3) * 100 + 100
local c = display.newImage( table[i].name, system.TemporaryDirectory, xpos, ypos)
c:scale( 0.4, 0.4 )
c.name = table[i].tvname
buttons:insert(c)
function c:touch( event )
if event.phase == "began" then
print(self, event.id)
end
end
c:addEventListener('touch', c)
end
end

sorting two dimensional array asp classic
So I have a 2d array that I want to Sort. I can sort it easily when one dimensional. I Hope you can help me guys. This is my Data. top5(0,0) = Greeting top5(0,1) = 2 top5(1,0) = VerifyingInformation top5(1,1) = 5 top5(2,0) = Calibration top5(2,1) = 4 I can sort It no problem when one dimensional. I'm using this code for one dimensional. For i = LBound(top5) to UBound(top5) For j = LBound(top5) to UBound(top5) - 1 If top5(j,1) < top5(j + 1,1) Then TempValue = top5(j + 1,1) top5(j + 1,1) = top5(j,1) top5(j,1) = TempValue End If next Next The result I want to have is this. VerifyingInformation 5 Calibration 4 Greeting 2
THIS WORKS FOR ME function sort_arr_mult(byref ArrTmp, ordPlace) ' ordPlace - the place of the order value in the array ' create the new array Redim arrRet (Ubound(ArrTmp, 1), Ubound(ArrTmp, 2)) for j = 0 to Ubound(ArrTmp, 2) orderVal = ArrTmp(ordPlace, j) if j = 0 then ' first enter insert to first column for i = 0 to Ubound(ArrTmp, 1) arrRet(i, j) = ArrTmp(i, j) next else ' check the first value if smaller or equal ' move the columnbs one field up ' at the end insert to currenct column for k = 0 to Ubound(arrRet, 2) if isEmp(arrRet(0, k)) then ' if empty fied the column for i = 0 to Ubound(arrRet, 1) arrRet(i, k) = ArrTmp(i, j) next exit for else if orderVal<=arrRet(ordPlace, k) then for x = Ubound(arrRet, 2) to k+1 step -1 for i = 0 to Ubound(arrRet, 1) arrRet(i, x) = arrRet(i, x-1) next next for i = 0 to Ubound(arrRet, 1) arrRet(i, k) = ArrTmp(i, j) next exit for end if end if next ' for k = 0 to Ubound(arrRet, 2) end if next sort_arr_mult = arrRet end function
It looks like you are actually performing a one-dimensional sort of the numeric value with an associated text string just along for the ride. Your example code is close but you will need 2 temp values to represent the array values you will be shifting around. For i = LBound(top5) to UBound(top5) For j = LBound(top5) to UBound(top5) - 1 If top5(j,1) < top5(j + 1,1) Then TempValue = top5(j + 1,1) TempText = top5(j + 1,0) top5(j + 1,1) = top5(j,1) top5(j + 1,0) = top5(j,0) top5(j,1) = TempValue top5(j,0) = TempText End If Next Next
