The error message is self explanatory. It expects a System.Data.DataColumnCollection but your are supplying a string. You could do something like
DataColumnCollection[] tableCol = new DataColumnCollection[10] {new DataColumnCollection() , new DataColumnCollection() , ..... };

Hi all,
From past 5-6 years i have bben taught that u should have a return statement in your function definition if ur code returns a value, but to my astonishment the following code does return a value, but threre is no return statement at all...
Public Function GetMaximumId(ByRef ColName As String, ByRef con As SqlClient.SqlConnection, ByRef TabName As String) As Long<br />
Dim SQL As String<br />
Dim dr As SqlClient.SqlDataReader<br />
SQL = "select isnull(max(substring(" & ColName & ",5,10)),'0') from " & TabName<br />
<br />
Dim cmd As New SqlClient.SqlCommand(SQL, con)<br />
dr = cmd.ExecuteReader<br />
dr.Read()<br />
If IsDBNull(dr.GetValue(0)) = True Then<br />
GetMaximumId = 1<br />
Else<br />
GetMaximumId = dr.GetValue(0) + 1<br />
End If<br />
cmd.Dispose()<br />
dr.Close()<br />
End Function
How does this thing work?

Its VB, what do you expect? The old VB way of returning a value (before it had the return statement) was to treat the function name as a variable. Assigning that variable a value returned that value....hence:
Public Function GetMaximumId(...)<br />
...<br />
If IsDBNull(dr.GetValue(0)) = True Then<br />
GetMaximumId = 1<br />
Else<br />
GetMaximumId = dr.GetValue(0) + 1<br />
End If<br />
...<br />

Hi,
I have craated an interface for generating the rdl file through c# (User will select some fields for group and some for details and report will be generated accordingly). I am generating the XML for the rdl according to the schema. And the report is running fine in my local system where i am using sqlexpress but is not working in production. The problem is coming with the datasource as follows.
An error has occurred during report processing.
Cannot create a connection to data source 'SOP'.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection
I am using Integrated Authentication, below is the datasource code generated by c#
<DataSource Name="SOP">
<ConnectionProperties>
<IntegratedSecurity>true</IntegratedSecurity>
<ConnectString>Data Source=SIGMASQL;Initial Catalog=SOP</ConnectString>
<DataProvider>SQL</DataProvider>
</ConnectionProperties>
<rd:DataSourceID>36a274d3-f283-4ac9-9f26-401ddf14f733</rd:DataSourceID>
</DataSource>
When i am pasting the RDL xml to my BI project's Report it is giving preview properly, but after deployment it is not coming.
I have tried with SQL Authentication also by removing the IntegratedSqcurity element and changin g the connection string to add "sa" userid, but still it doesn't run and gives the same error and if i refresh the report with the refresh button of report viewer, it shows some Wrong String Format error.
When i am editing the dataset in the report designer(BI Project), the connection string is not storing password and username info in the xml of the rdl, i read somewhere that it stores these values in VS2005 and reporting service database with some encryption and don't keep in the xml. So it is seeming to me that i am not sending these credentials to reporting service while deployment through my c# code. Below is my deployment code
byte[] byteRDL;System.Text.UTF8Encoding encoder = new UTF8Encoding();
byteRDL = encoder.GetBytes(reportDefination);
Property[] rsProperty = new Property[10];
//Property property = new Property();
Warning[] warnings;
warnings = rs.CreateReport(reportName, "/QuoteReports", true, byteRDL, null);
But i have no idea why it is not even running with Windows Authentication also.
I am in big trouble guys. Pls help. I have to show it to my client..

I am working with MOSS 2007. Problem scenario as follows
1.We have developed one portal by using SharePoint server 2007 and this portal has been enabled for intranet and extranet environment.
2. Authentication used for this particular portal is Windows NTLM authentication.
3. User who is logging from extranet (From internet i.e. out side domain) will get initial authentication prompt, once user provides his credentials he can able to login in to the portal and he can access all pages around the portal except document link from document library with out any extra authentication prompt.
4. But if user is accessing any document from any document library, system is asking authentication and this is for every time and for every document library.
5. As per customer requirement we need to stop this unwanted authentication prompt.
Please let me know any solution available ASAP.

Thanks in Advance !!!!

What? This is a bizzare request. What are you really wanting to know?

How do you know there are six ? Have you tried finding info on the web ? Or in your course notes ?

I'm not sure about the number six. Whatever the objects are present in ASP.Net, please let me know
|
|
|
|
|
I think you're getting confused. In classic ASP there were 5 objects available:
Request
Response
Server
Session
Application
In ASP.NET there are hundreds (if not thousands) - every object defined in the .NET runtime is available for use.

I have no idea what you mean, but I'd guess that it's not possible. Your server side creates html which is sent to the client when the client requests it. The client side does not exist while the server side is running.

Are both forms visible at once ? If so, then if they are not parent and child, I doubt you can do that, without polling using AJAX. If only one is visible at a time then the form will work out the new state for itself as it reloads.

Hi
In my webform(webform1.aspx), i have an iFrame control, along with with many web controls.
The "src" attribute of it refers to another webform.(webform2.aspx)
I want text to appear in the frame on clicking a button which fetches the
value from db. Am using a session variable to hold the text to be assigned for iframe.
And am using the following code in WebForm1.aspx
<br />
private void Button1_Click(object sender, System.EventArgs e)<br />
{<br />
Session["Cont"] = "This is a page";<br />
<br />
HtmlGenericControl frame1 = (HtmlGenericControl)this.FindControl("txtFrame");<br />
<br />
frame1.Attributes["src"] = "WebForm2.aspx"; <br />
<br />
Server.Execute("WebForm2.aspx");<br />
Response.ClearContent();<br />
}<br />
And in WebForm2.aspx,Page_Load(..)
<br />
if(Session["Cont"]!=null)<br />
{<br />
Literal1.Text = Session["Cont"].ToString();<br />
}<br />
The problem is when i click the button in WebForm1.aspx, along with actual text, a textbox with some characters is appearing in the iFrame though there's no other control in the target(Webform2.aspx) other than Literal control.
Please help me in finding out the actual problem and its solution.
Thanks
