Hello,
I am trying to attach a signature with the proxy and trying to do some operation like below:
wse.RequestSoapContext.Security.Tokens.Add (new X509SecurityToken(cert));
X509SecurityToken crtTkn = new X509SecurityToken(cert);
http://www.eggheadcafe.com/articles/20021231.asp
I am not able to see a "RequestSoapContext" under my proxy of webservice...? Could some one please suggest. What I might be missing. I have installed WSE 2.0

Looks like you've encapsulated your database logic well enough that you should only need to update your queryRows method and your setConnectionString method. There isn't any difference in your code that you've posted. Lookup SqlConnection and SqlCommand for a good start on how to rewrite your methods.
Etienne wrote: DBFunctions.queryRows("SELECT COUNT(Email) FROM Company WHERE Email = '" + uname + "' and Password = '" + password + "'")
As an aside, this is really bad practice for any application regardless of wither it's Access or SQL Server.
Instead you should do the following:
<br />
"SELECT COUNT(Email) FROM Company WHERE Email = @email and Password = @password"<br />
If you are using SQL Server pass this to the SqlCommand object. If you're using Access use OleDbCommand. Then regardless of the command object set the value of @email and @password using Parameters collection of the command object you create. You open yourself up to SQL Injection attacks otherwise.
Also, when you're updating data you're open to cross-site scripting attacks (XSS) unless you sanitize the data you get from the user using either Server.UrlEncode or Server.HtmlEncode. like this:
<br />
Dim email As String = Server.HtmlEncode(Request.Form("email"))<br />
<br />
' now you can pass your variable "email" to your SQL command<br />
<br />
<br />
I didn't see any examples of how you're updating data in your code above, but seeing your queries makes me think you aren't sanitizing your inputs either.
Sorry if the code samples don't compile, I haven't used VB in at least 6 years and I've never really used VB.NET.

Hi, I kind figure out the problem why the FormsAuthentication cookie can't be set, because just after the authentication it brings me back to the same page with the message that my session has been expired.
Lets see my webconfig.
<system.web>
<authentication mode="Forms">
<forms path="BackOffice" loginurl="BackOffice/Default.aspx?state=Timeout" protection="All" timeout="1">
</forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
</system.web>
The state=Timeout is caught to show an alert saying that the session has been timed out
The code that i use just after a successful authentication:
'FormsAuthentication.SetAuthCookie(tbxEmail.Text.Trim, False)
FormsAuthentication.RedirectFromLoginPage(tbxEmail.Text.Trim, True)
Response.Redirect("Home.aspx")
After a successfull authentication I don't get directed to the Home.aspx page.
When i set the following in the webconfig:
<forms path="BackOffice" loginUrl="BackOffice/Default.aspx?state=Timeout" protection="All" timeout="1" cookieless="UseUri">
but than my string changes to something like:
http://localhost:4190/TEST/(F(DkeaiAh5OWpUmiVajjisadVvodQMLp1lpg4yu8pQK_PlxqApl5udnh7iAx1Yi8KhNbLIx6pQkytYVuhnwCj7GmfkbmpD-2IxXSxyilQM5HDrQ9-byppwLdbd_uBxEeSNdo5UNcPd9nxQxW0ZU3o3Sw2))/BackOffice/Home.aspx
What I am doing wrong? How i can use normal cookies zo i don't need to have the UseUri flag?
Thanks

Your call to Response.Redirect doesn't get called because you're calling RedirectFromLoginPage before it. Do something like this:
<br />
<forms .... other attributes .... defaultUrl="~/BackOffice/Home.aspx" cookieless="UseCookies" /><br />
And your code can just be:
<br />
FormsAuthentication.RedirectFromLoginPage(....)<br />
You don't need to do anything special to use cookies. Calling RedirectFromLoginPage will set the user's cookie and the FormsAuthentication module will take care of managing the session ticket in the cookie.
And if you're session is still timing out, set your timeout to something more than 1 minute. 30 minutes is the default. 1 minute will never work in a real application, it would only be valid for testing what happens when the session times out. Here's the documentation for the <forms> element: http://msdn2.microsoft.com/en-us/library/1d3t3c61.aspx[^]
|
|

|

Well i tried it, I've set the timeout to 55 minutes, added the defaultUrl and the cookieless attribute.
I changed all my code to that single line FormsAuthentication.RedirectFromLoginPage(email, false)
Well i can't seem to get it work, it calls immediately the login page again.
http://localhost:4190/TEST/BackOffice/Default.aspx?state=Timeout&ReturnUrl=%2fTEST%2fBackOffice%2fHome.aspx
I don't get it. Any idea why this is happening?
|

Have you checked FormsAuthentication.CookiesSupported to verify if the client supports cookies?
If that doesn't help, post your code and config file again to show us what it looks like now with your changes.
|
|
|
|

Sorry, i was a bit out.
I did a check on FormsAuthentication.CookiesSupported and it says true (i logged it to a file)
So i am a bit clueless here why this is happening.
webconfig:
<br />
<system.web><br />
<sessionState timeout="60"/><br />
</system.web><br />
<br />
<system.web><br />
<authentication mode="Forms"><br />
<forms path="BackOffice" loginUrl="BackOffice/Default.aspx?state=Timeout" defaultUrl="BackOffice/Home.aspx" timeout="55" cookieless="UseCookies"><br />
</forms><br />
</authentication><br />
<authorization><br />
<!--<allow users="*"/>--><br />
<deny users="?"/><br />
</authorization><br />
</system.web><br />
The validation code:
Protected Sub btnValidate_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnValidate.Click<br />
Dim dt As DataTable = db.GetData("SELECT Active FROM tblUsers WHERE Email = '" & tbxEmail.Text.Trim & "' and Password = '" & Replace(tbxPassword.Text, "'", "''") & "'")<br />
<br />
If (dt.Rows.Count = 0) Then<br />
' This means that the combination of the email address and the password could not be found in the database<br />
lblLoginMessage.Text = CType(ViewState("vsAlerts"), Hashtable)("Alert1").ToString<br />
Else<br />
If (CType(dt.Rows(0)(0), Int32) = 0) Then<br />
' This means that the user is not allowed to log in, the Active bit is set to 0<br />
lblLoginMessage.Text = CType(ViewState("vsAlerts"), Hashtable)("Alert2").ToString<br />
Else<br />
Session.Add("User", tbxEmail.Text.Trim)<br />
Session.Add("Date", DateTime.Now.ToString)<br />
Session.Add("Active", 1)<br />
<br />
Common.LogInfo("FormsAuthentication.CookiesSupported: " & FormsAuthentication.CookiesSupported(), 3, Parameters.LOG_FILE, "clssDbAccess.SetData")<br />
<br />
FormsAuthentication.RedirectFromLoginPage(tbxEmail.Text.Trim, False)<br />
End If<br />
End If<br />
End Sub

hi all,
i am developing a content management system in asp.net with C#. i have a master page named "Master1.master" with 5 content place holders-"cphHeader, cphLeft,cphCenter,cphright,cphbottom". i have another default.aspx page which is inherited from the "Master1.master". it takes as input,the following fields from the user :
1. text to be displayed.(Textbox)
2. Content holder where the text will be displayed (dropdown having names of all the 5 content holders mentioned above.).
these things entered by the user are stored in the database. The text entered by the user should be displayed in the content holder mentioned above.
How do i do it?? is there any facility which helps us access the content place holders on the default.aspx.cs page.
thanks in advance.please reply as soon as possible.

You can add it to the CPH Control's collection:
ContentPlaceHolder cph = (ContentPlaceHolder)Master.FindControl("PrimaryContent");<br />
if (cph != null)<br />
cph.Controls.Add(new LiteralControl("The text string"));
|
|
|
|
|
Im not too sure on this but would you be able to put the content holders in a global or common methods page, this way you can acces them from any page.

Hi guys,
Please forgive me, if it is a question frequent asked.
As you know, when we tried to submit a asp.net page with characters something like '<test>' filled in, and we would get an error as the subject.
How can the exception "A potentially dangerous Request.Form value was detected from the client" be handled without setting the validateRequest to false in the page directive or in the web.config file? because I just want to void this ASP.NET feature for only a single textbox, Any suggestions?
Thanks, Ming.

Set ValidateRequest=false on the page.
|
|

Hi N a v a n e e t h,
Thanks for your solution, but I think you don't understand what I am asking, you are alright, that is my fault, I didn't hightlight the key words.
The key word is without setting the validateRequest to false in the page directive or in the web.config file?
Cheers,
Ming

Ahh, I didn't noticed that  . I don't think there is other way to do this. BTW, what is the problem for turning it off in page level or web.config ?
|
|
|
|
|
because the basic requirement is that I provide a online html editor (implemented by using textbox) which allows user types in html markup , and submit to database.
and also I have other textboxes on the same page which do need the asp.net pagevalidate feature,
is any solution? any suggestion would be appricated!
Cheers,
Ming

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Session["mysession"].ToString() != null)
{
Label1.Text = "Welcome " ;
}
else
{
Response.Redirect("Login.aspx");
}
}
}
I have the above code in one aspx page. Before logging in if someone opens this page, it should open Login page. But instead of showing theLogin page, it shows Server Error. Any one have an idea.
