I know that I can create session variables and pass those values from one
screen to another, but is there not a way to makes variables from one scree
n available to another screen other then session variables? Is there not a
way to create properties in the one screen and then pass some sort of
reference to the screen you are calling?
Can you point me to an example or an article on how to use?
Thanks in advance for your assistance!!!!!!!!Passing Values from Aspx to Aspx
Although ASP.NET usually submits data to the current page for processing,
there are times when you need to pass values from the controls on one page
to controls or routines on another ASP.NET page.
This is a cookbook style tutorial that shows you how to pass from one page
to another. For a deeper explanation, see the Microsoft Help file references
at the bottom of the page.

Passing values across webforms that use Master pages
Sorry to create a new thread on an old post but I didn't get a viable answer
and thought that the odds were against me getting one unless I started a new
thread.
and thought that the odds were against me getting one unless I started a new
thread.
My question was this:
I want to pass a string variable from default3.aspx to default2.aspx.
I create a property in default2.aspx, called "X", and assign a value. I then
call Server.Transfer("default3.aspx")
In default3.aspx I have this code:
Dim Default3 As Default3 = ctype(Context.Handler, Default3)
Dim PassedString As String = Default3.x
This will work fine as long a default 3 is not a webform that references a
master page.
If it is, it tells me that "Default 3" is an undefined type. As a result,
the only way that I know o get it to work is to turn of Option Strict and
change it to this:
Dim Default3 As Object = Context.Handler
Dim PassedString As String = Default3.x
I really dont want to turn off Option Strict or resort to looselt typed
variables.
How do I correct this?
Chad,
Try either putting the String name=value combo on the querystring, or into
the HttpContext.Current.Items Collection. Not reasonable to expect a
"property" of a page to survive a server.transfer or Response.Redirect.

Actually, it does work if you define Default3 as an Object. I was trying to
strongly type the variable Default3 as an object of type "Default3" and it
did not recognize the class "Defaulyt3" outside of the Default3 class.
Try it. It does work.

passing values from form to form
I was wondering if it is possible to pass values from one aspx page to another aspx page using properties?
I want to create a property on the 2nd aspx page lets say Name(), and pass in the values from the first aspx page. I know how to pass values like this to a user control, but is it possible to pass it to another aspx page?> I was wondering if it is possible to pass values from one aspx page to another aspx page using properties?
You can sort of do this, but not as directly as you're suggesting.
In your firstpage.aspx:
Public Sub Button_Click( sender As Object, e As EventArgs )
Session( "Name" ) = "Value from textbox, or wherever"
Response.Redirect( "secondpage.aspx" )
End Sub
Then, in your secondpage.aspx:
Private _name As String
Public Property Name As String
Get
Return _name
End Get
Set
_name = Value
End Set
End PropertyPublic Sub Page_Init( sender As Object, e As EventArgs )
Name = Session( "Name" )
End Sub
If that doesn't help, perhaps you can explain more fully what you're trying to do.
That's what I'm trying to do. I knew that I can use session variables, just wondering if there's any other way to accomplish this.
You can store information into the QueryString as well.
Well, you can't directly access the second Page's properties from the first page, no.
After all, the second Page is not instantiated until the first is destroyed. So there can be no direct messaging between them.
It is for this reason that session variables exist. So, for "form to form" communication, session variables are ideal.
You can also create a single form thatacts like more than one form. If you're trying to keep information "alive" during a certain series of tasks, this might be a better way to go.

Passing values into SQL Server
Hi: I create two textboxes and a button and try to pass values from the

Passing Variable to XSLT
I have a ASP.NET application written in VB.net 2003 with a form I am
using to create an export file. Using XslTransform class I have a form
that collects data and executes a stored procedure to pull information
from my SQL Database. I would like to include information from a
textbox on the form in the XSL stylesheet. Can some one please explain
how I can pull information from my code and pass it to the stylesheet?
Thanks

One thing that comes to mind, though I'm sure I'm overcomplicating
it... is to make the XSLT an aspx page (you can specify the
appropriatae content-type in the codebehind) and pass it a query
paramater (MyXslt.xsl.aspx?Id=7). I do this with my ECMAScript
(JavaScript) at times like "GetFirefoxSVGInformation.js.aspx?id=314"
This would work clientside, but should be close on serverside too.
Peter,
Thanks for the quick reply! I'll work with that information.
Charles
Being new to all of this, I need to ask one more question. Once the
variable is passed, how do I insert it into my xslt?
<xsl:for-each select="PrintChecks/tblChecks">
<xsl:text>TRANS CHECK </xsl:text>
<xsl:text></xsl:text><xsl:value-of select="fldFirstName"/>
<xsl:text> </xsl:text><xsl:value-of select="fldLastName"/>
var needs to go here
...
/xsl:for-each
Thanks again.
I was able to figure everything out thanks to the link Peter sent.
Just goes to show ya that a little help from some one in these groups
goes a long way!
Thanks again!

Passing windows credentials from server to server.
Hello,
I have been desperately trying to programmatically authenticate a windows
user, create their credentials, and then redirect them to a different server
while passing the credentials at the same time so that they don't have to
login again.
Specifically, I have two webservers in the same domain. When I have a user
go to Webserver A (which uses basic authentication) I programmatically
create either a user credential or impersonate a user context (for now it's
hardcoded, but in the future it would be entered in forms). Then, I want to
let that user access a page on Webserver B (which uses basic
authentication), but I don't want them to have to login again -- rather, I
want to use the user context that I programmatically created on Webserver A.
For instance, here is an example of the code I use to create the user
credentials:
Dim strURI = "http://www.whatever.com"
Dim myCred As New NetworkCredential("userid", "password", "domain")
Dim myURI As New Uri(strURI)
Dim myCache As New CredentialCache
myCache.Add(myURI, "Basic", myCred)
From this, I have attempted to use WebRequests and WebResponses to somehow
allow me to direct the browser to a different page, and use the credential I
have generated. The most I can do, however, is create the request and
receive the response:
Dim myWebRequest As System.Net.WebRequest =
System.Net.WebRequest.Create(strURI)
myWebRequest.Credentials = myCache
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
If only I could use the response.redirect method, and somehow pass the
credentials with the redirection (like you can with the webrequest), it
could work!
I have also attempted to use the LogonUser API (from the advapi32.dll), and
impersonate a user based on the proper logon information -- this works, and
I'm able to successfully impersonate the user, but again, I don't know how
to pass along the user context to a different page.
I know that many people will say "just use form based authentication," but
this will not work for me, as I want this to work with tools like Outlook
Web Access, which requires windows authentication.
Any help would be greatly appreciated. Thank you!!
Wadewhile your only option is to use redirect to
http://username:password@.somesite.com (if using basic), I wouldn't do that
either.
anything else -- can't do.

if they are your own servers, you could set up a webservice to transfer
session info back and forth...

Huh!
I never you could do that to pass login information to a site with basic
authentication. Is there a name for that? Something that would allow me to
look it up in MSDN? I wonder what the security considerations are. If used
with SSL, is it safe? Etc.
Thanks for the idea, though ... I'll look into it some more.

Okay, as I've been playing with the method you mentioned, I've noted the
following.
If I create a login form, and then programmatically create a URL string, and
then redirect to that URL, it prompts me to login. However, if I register a
vbscript that uses window.location to redirect the user to this script, it
doesn't. Does the response.redirect not work?
For example, this is what I use for the response.redirect:
Dim strURL as string
strURL = "http://" & txtUserID.Text & ":" & txtPassword.Text &
"@.mydomain.com"
response.redirect(strURL)
That doesn't work, and it prompts me to login.
However, I can get the following to work fine:
Dim strURL as string
strURL = "http://" & txtUserID.Text & ":" & txtPassword.Text &
"@.mydomain.com"
Dim txtScript as new System.Text.StringBuilder
txtScript.Append(vbCr & "<script language=vbscript>")
txtScript.Append(vbCr & "window.location = """ & strURL & """")
txtScript.Append(vbCr & "</script>" & vbCr & vbCr)
Page.RegisterStartupScript("redirect", txtScript.ToString)
When I redirect from the client, this works fine. Additionally, if I simply
type in the address into the browser, it works properly.
Any ideas? Will I have to do this from the client?
Thanks,
Wade

I don't like this approach (of passing credentials like this) at all.. it's
visible in the address bar.. so I'm not sure this is really a good idea.
it's an HTTP thingie.. so you would want to look at it there.. MSDN may have
it.. but may not...

See, I do not experience it displaying in the address bar. I have not been
able to find anything in MSDN concerning this, but I started to think that
all this method does is mimic what basic authentication does -- I mean,
basic authentication is unencrypted, clear text. Is employing this method
any different than using basic authentication? In both cases, obviously, it
would be worthwhile to encrypt using SSL.
I still wish I understood why this solution would not work if redirected
from the server, via response.redirect, but will if it is redirected at the
client. Even if this isn't a good solution, I'd like to know the answer to
that.

Look at HTTP specs... see what it says for 302 (that's what
response.redirect really is)...
as I said, all this is http stuff.. so MSDN may not have it (just like they
dont' have http specs there...) you'd probably want to start looking at
w3c's site

I have been desperately trying to programmatically authenticate a windows
user, create their credentials, and then redirect them to a different server
while passing the credentials at the same time so that they don't have to
login again.
Specifically, I have two webservers in the same domain. When I have a user
go to Webserver A (which uses basic authentication) I programmatically
create either a user credential or impersonate a user context (for now it's
hardcoded, but in the future it would be entered in forms). Then, I want to
let that user access a page on Webserver B (which uses basic
authentication), but I don't want them to have to login again -- rather, I
want to use the user context that I programmatically created on Webserver A.
For instance, here is an example of the code I use to create the user
credentials:
Dim strURI = "http://www.whatever.com"
Dim myCred As New NetworkCredential("userid", "password", "domain")
Dim myURI As New Uri(strURI)
Dim myCache As New CredentialCache
myCache.Add(myURI, "Basic", myCred)
From this, I have attempted to use WebRequests and WebResponses to somehow
allow me to direct the browser to a different page, and use the credential I
have generated. The most I can do, however, is create the request and
receive the response:
Dim myWebRequest As System.Net.WebRequest =
System.Net.WebRequest.Create(strURI)
myWebRequest.Credentials = myCache
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
If only I could use the response.redirect method, and somehow pass the
credentials with the redirection (like you can with the webrequest), it
could work!
I have also attempted to use the LogonUser API (from the advapi32.dll), and
impersonate a user based on the proper logon information -- this works, and
I'm able to successfully impersonate the user, but again, I don't know how
to pass along the user context to a different page.
I know that many people will say "just use form based authentication," but
this will not work for me, as I want this to work with tools like Outlook
Web Access, which requires windows authentication.
Any help would be greatly appreciated. Thank you!!
Wadewhile your only option is to use redirect to
http://username:password@.somesite.com (if using basic), I wouldn't do that
either.
anything else -- can't do.

if they are your own servers, you could set up a webservice to transfer
session info back and forth...

Huh!
I never you could do that to pass login information to a site with basic
authentication. Is there a name for that? Something that would allow me to
look it up in MSDN? I wonder what the security considerations are. If used
with SSL, is it safe? Etc.
Thanks for the idea, though ... I'll look into it some more.

Okay, as I've been playing with the method you mentioned, I've noted the
following.
If I create a login form, and then programmatically create a URL string, and
then redirect to that URL, it prompts me to login. However, if I register a
vbscript that uses window.location to redirect the user to this script, it
doesn't. Does the response.redirect not work?
For example, this is what I use for the response.redirect:
Dim strURL as string
strURL = "http://" & txtUserID.Text & ":" & txtPassword.Text &
"@.mydomain.com"
response.redirect(strURL)
That doesn't work, and it prompts me to login.
However, I can get the following to work fine:
Dim strURL as string
strURL = "http://" & txtUserID.Text & ":" & txtPassword.Text &
"@.mydomain.com"
Dim txtScript as new System.Text.StringBuilder
txtScript.Append(vbCr & "<script language=vbscript>")
txtScript.Append(vbCr & "window.location = """ & strURL & """")
txtScript.Append(vbCr & "</script>" & vbCr & vbCr)
Page.RegisterStartupScript("redirect", txtScript.ToString)
When I redirect from the client, this works fine. Additionally, if I simply
type in the address into the browser, it works properly.
Any ideas? Will I have to do this from the client?
Thanks,
Wade

I don't like this approach (of passing credentials like this) at all.. it's
visible in the address bar.. so I'm not sure this is really a good idea.
it's an HTTP thingie.. so you would want to look at it there.. MSDN may have
it.. but may not...

See, I do not experience it displaying in the address bar. I have not been
able to find anything in MSDN concerning this, but I started to think that
all this method does is mimic what basic authentication does -- I mean,
basic authentication is unencrypted, clear text. Is employing this method
any different than using basic authentication? In both cases, obviously, it
would be worthwhile to encrypt using SSL.
I still wish I understood why this solution would not work if redirected
from the server, via response.redirect, but will if it is redirected at the
client. Even if this isn't a good solution, I'd like to know the answer to
that.

Look at HTTP specs... see what it says for 302 (that's what
response.redirect really is)...
as I said, all this is http stuff.. so MSDN may not have it (just like they
dont' have http specs there...) you'd probably want to start looking at
w3c's site

password
how i create a textbox for password using web controls
Paramita-
Are you asking how you can adding a TextBox to your page that hides the text input (a.k.a. password mode)?
If so, the solution is very easy. Simply add an ASP.NET Textbox to your page and set its TextMode property to Password, like this:
<asp:textbox runat="server" id="myTxtBox" TextMode="Password" />
Thanks~
Password field
In ASP.Net I would like to create a text box that is a Password Field.
How do I do that ?
When I use the Textbox Field (from Toolbox - Standard), I did not find
anything there that can make it a password field.
When I use the Input (Password) Field (From Toolbox - HTML), in my
Submit command button when I do Request.Form("txtPassword") or
Request.QueryString("txtPassword") it returns nothing.
<asp:TextBox ID="txtPassword" runat="server" TextMode="Password" />
When I click on the hyperlink you wrote
news:1177277182.866667.28220@.b75g2000hsg.googlegro ups.com...
it says "Page not found".
Can you please retype the link ? Thank you very much.
>
<asp:TextBox ID="txtPassword" runat="server" TextMode="Password" />
You can only click on that hyperlink from a newsreader, not from a browser.

See my earlier reply, MArk.
He means the news: protocol hyperlink which is quoted
in your reply because you used a newsreader to reply to him.
He's using a browser...and the news: protocol doesn't work in browsers
unless it also has the double slashes and the server's address.
