Hi,

We have .Net Framework 1.1 and 2.0 installed on the same server. We now have new requirements that will need AJAX. We can either install:
1. .Net Framework 3.5
OR
2. AJAX Toolkit (with existing .Net Framework 2.0)

We do not want to have any issues with existing applications due to this. Please suggest which will be a better approach and what will be the impact on existing applications using older versions?
Are there any specific guidelines for having multiple versions on same server?

You don't need to install anything, unless what you mean is, we don't know enough to use AJAX and will need to use a Microsoft framework instead. AJAX is nothing to do with ASP.NET, only the Microsoft wrapper library is.

If you don't bind on postback then I'd be checking to make sure that the viewstate is not turned off for the page.

Problem with BCP in C#

I am working on this application(asp.net 1.1,sql server 2000) that has a huge database , in the frontend there is a provision

to generate a csv file by running a stored procedure which can fetch 50000 records(approx), to acieve this I've used the

following:-
1) running forloop iterating through the dataset and creating a comma separated string, then creating the csv file, but this

process slows down the server immensely when data fetched is huge.
2) DTS packages is failing, because when I am creating a new package and click the defeine column button, the SQL Enterprise

manager just closes itself after a few seconds.
3) BCP command, sometimes works sometimes does not. The code used for running bcp in C# is :-

System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = "bcp";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.Arguments = @"""exec ETH11.dbo.usp_DownloadInvoiceforDalkia "" queryout ""D:\NewLookLogs\Invoice.csv"" -c -t ,

-T -S";
proc.StartInfo.Arguments = proc.StartInfo.Arguments.Replace("usp_DownloadInvoiceforDalkia ","usp_DownloadInvoiceforDalkia

"+"'"+xSupplierID+"',"+"'"+xBuyerID+"',"+"'"+xFromDate+"',"+"'"+xToDate+"',"+"'"+xType+"',"+""+xCurrentOnly+","+""+xDateType+

","+""+xStatus+","+""+xAllStatus+","+""+xContentType+","+"'invoice.csv',"+"'"+Session.SessionID+"'");
proc.Start();
proc.WaitForExit();

i tried that to but the problem is where ever i m sending mail it comes from the user name that we use as google credential.
but i have a feedback form where i am taking email address from user and i want that email address as a from email. so that my web master can directly hit reply button when he received mail for further transactions.

I have one field of Gridview populated from a DB (MS SQL Server) this way:

One field is (for example) http://google.com

<asp:TemplateField HeaderText="Link" 
                       SortExpression="Link">               
    <ItemTemplate>
   
    <asp:HyperLink ID="HyperLink1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "URL") %>'  DataNavigateUrlFields="URL" NavigateUrl='<%# DataBinder.Eval(Container.DataItem, "URL") %>' />
    

    </ItemTemplate>
    <EditItemTemplate>
    <asp:TextBox ID="URL" runat="server" 
                 Text='<%#Bind("URL") %>'>
    </asp:TextBox>
    </EditItemTemplate>
    <FooterTemplate>
    <asp:TextBox ID="URL" runat="server" width="65px">
    </asp:TextBox>
    </FooterTemplate>
    </asp:TemplateField>

The problem is, when I click the http://google.com field, I go to http://google.com%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20\%20%20%20%20%20%20%20%20%20%20(...)

20 is the ID of the field..

What am I doing wrong ?

Your html seems ok. %20 means url encoded space. Did you check the values in database? Is there any empty space in url?

Maxdd 710-Nov-09 17:25

Well, the field in the table of DB is char(100).. (MS SQL Server 2005)

Maybe if I use VARCHAR I solve the problem? Not with my pc right now to test.

I honestly didnt understood what you just said about trimming the results but tomorrow I will try changing type of variable on DB and see if it solve the problem..

_Damian S_10-Nov-09 18:02

When you select the value from the database, use the TRIM() function to remove leading and trailing spaces.

In SQL Server, this is ltrim(rtrim(FIELDNAME))

Maxdd 711-Nov-09 8:44

That's exactly what I said...

Using VARCHAR everything works fine!

So many time wasted...

Thanks for your help!
