Hi Anil Pal(Especially for You),
Get into Code project site and login with your email id and password.Now Click on "Sign out" and You will be seeing site with No login account.Now click on back(History) button,Then you will see some screen with only login Id, but not password.This is called authentication.This is what, i was searching for.Feel free to ask some more.Ok Bye.
Best regards,

Mr Sundeep,
Have a look on the code I Posted earlier.. Even if you click Back button of the Internet Exploer, On Page Load event it will check the Session("UserID"), Obviously it will be empty, because you made it clear on signout...So immediately it will redirect to login page.
Never you can see the backpage after you logged out.

See Sandeep,
On Every Page, Except Login Page, In Page Load Event Just write this Code.
If Trim(Session("UserID")) = "" Then
Response.Redirect("ErrorPage.aspx")
End If
Don't forget to clear the Session("UserID") value to "" on Logout or Session End

are you surely check the properties windows for the logout button redirection to loginpage check it and if it is already done by you then try this:
1.make sure of session closing by session.abandon();
2.make sure to check if session is not null on page load if so
make sure to redirect the user to login page in case of session.tostring()==null;[not real code e.g. only].
and pls read some books before coming here.
Have Fun,

Hi,
I am attempting to unit test some code i have written. Unfortunately I am having an issue when using a generic list of an object type I have defined. I'm basically checking to see that this list is equal to 0 and if it is return false. However when the check is performed I get a null exception error. Below is an example (not exact code) of the code I'm trying to test and the bold and underline is where i'm receiving the error. Thanks in advance to all that reply.
private Car _car = new Car();
//constructor
public CarValidation(Car carDetails)
{
if (carDetails == null)
throw new ArgumentNullException();
else
_car = carDetails;
}
public bool CheckForValues()
{
bool valid = true;
if(_car.OilPressure == null)
valid = false;
if (_car.TirePressure == null)
valid = false;
if (_car.GasAmount == null)
valid = false;
if (_car.Mp3SongsLoaded.Count == 0)
valid = false;
return valid;
}
|

|

What is the type of Mp3SongsLoaded? You haven't shown the piece of code where you are instantiating type of Mp3SongsLoaded. So I assume, that might be NULL and you are accessing Count on a NULL reference.
BTW, how come you thought ASP.NET forum will be appropriate for this question?

Hi All,
I am using itexthsharp to export my gridview to PDF and one of my column is an image and I am stuck on to add it to the code. Here is the code I am testing:
Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim columnCount As Integer = GridView1.Columns.Count
Dim rowCount As Integer = GridView1.Rows.Count
Dim tableRows As Integer = rowCount + 3
Dim grdTable As New iTextSharp.text.Table(columnCount, tableRows)
grdTable.BorderWidth = 1
grdTable.BorderColor = New Color(0, 0, 255)
grdTable.Cellpadding = 5
grdTable.Cellspacing = 5
Dim c1 As New Cell("Exporting paging enabled GridView to PDF example")
c1.Header = True
c1.Colspan = 2
grdTable.AddCell(c1)
Dim c2 As New Cell("By amiT jaiN , amit_jain_online@yahoo.com")
c2.Header = True
c2.Colspan = 4
grdTable.AddCell(c2)
grdTable.AddCell("Name")
grdTable.AddCell("Description")
grdTable.AddCell("Price")
grdTable.AddCell("Thumbnail")
For rowCounter As Integer = 0 To rowCount - 1
For columnCounter As Integer = 0 To columnCount - 1
Dim strValue As String = GridView1.Rows(rowCounter).Cells(columnCounter).Text
grdTable.AddCell(strValue)
Next
Next
Dim Doc As New Document()
PdfWriter.GetInstance(Doc, Response.OutputStream)
Doc.Open()
Doc.Add(grdTable)
Doc.Close()
Response.ContentType = "application/pdf"
Response.AddHeader("content-disposition", "attachment; filename=AmitJain.pdf")
Response.[End]()
End Sub
As you can see I need to include the "Thumbnail" column as an image.
Thank you

I have a web service that uses web methods which pass strong type parameters.
These parameters are objects generated from xsd's through xsd.exe. When the web service is added as a reference to another app, as I understand, wsdl is generated from this and passed through SOAP headers.
I have a web service in a separate project in my solution. I add a reference from another project and the reference works fine - I can pass the strong type parameters that have been defined.
However, I've deployed the web service to a different server and I'm not able to call the method - "Unable to connect to the remote server"
I think this might have something to do with a <webservices> setting that needs to be added to Web.config for this type of request.
Can someone provide some guidance on this?

Hi all,
I have code for menu in page.aspx, but now i want write this code in page.aspx.vb for menu programming.
How i can convert this code?
this is my code:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Panel ID="Panel1" Runat="Server">
<asp:LinkButton ID="LinkButton1" Text='<%# Eval("nam") %>' Runat="Server"
PostBackUrl='<%# Eval("id","Page.aspx?id={0}") %>'
ForeColor="#990000"
Font-Underline="False"/>
</asp:Panel>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
i didn't use SqlDataSouece, and i used dataset for filling gridview.
Now how i can write these code in page.aspx.vb instead of using Eval in page.aspx?
Thank you
Hoda

Handle RowDataBound[^] event, use FindControl() to find the link button and set the PostBackUrl.
Looks like you need a HyperLink button here, not LinkButton.

How do I suppress a specific warning for asp.net. I know when you are building a windows app you can go the the project properties and under the build tab you can suppress a specific warning number. What would be it's equivalent in ASP.Net for VS 2008.
|
|
|
|
|
i think in asp.net nothing exist like suppression of warning....
only windows application provide this functionality

I did find this msdn.microsoft.com/en-us/library/3y20cc1z(VS.80).aspx on msdn, but I haven't found the exact syntax. So, I know you can do it.
|
|
|
|
|
|
sometimes if your project is big enough then you are going to run into a warning that just isn't valid for that function. Especially if you are going in behind someone else's code. I appreciate the effort though.
I actually found the syntax after half a day of trying code and looking. According to one blog this is the syntax. compilerOptions="/nowarn:42105". But it doesn't seem to be suppressing the warnings..
If someone "who has actually" put this in the web.config file has any insight it would be greatly appreciated.

Hello,
First of all, I hope people won't eat me for asking this, but the fact is I'm kind of stuck on it.
I have a problem displaying my .aspx file in any other browser except Internet Explorer.
When I try to use lets say FireFox/Google Chrome or what ever other browser, it automatically starts
to download my .aspx file. Now the thing is, I can't understand what I'm doing wrong or what have I
missed out.
1) It all works when I test it with "Build+Run"
2) It displays in IE
I've read something about IIS but.. I don't get it, how should I use it.
Maybe someone kind enough would enlighten me on this matter.
Thanks! (from someone who started learning C#/ASP.NET)

So are you saying that it doesn't run on the server, but it does on your local machine?
|
|
|
|
|
Indeed, and now I think I understand what the problem is.
Apparently the server doesn't support ASP.NET environment or something. Since thats the only
answer I could come up with.
|
|
|
|
|
If this is for your company then you need to get your server guys to set that up if you are doing this on your own here is a website that does webhosting for windows that are probably ready to go. http://order.1and1.com does[^]

Thanks, I'll take a look into that
