Hi guys,
I've been working on a simple user control that creates a table, filled with images from piecing together bits of HTML.
Using Response.Write() to display every line, this takes about 3-4 seconds to execute. The obvious problem with this is that the table appears at the top of the page, not at the position of the user control. Using a label and buffering all the HTML to a string takes around 2-3 times as long! No extra code or anything just something along the lines of...
<br />
string buffer = "";<br />
<br />
buffer+=...;<br />
buffer+=...;<br />
<br />
Label1.Text = buffer;<br />
What is causing this massive performance hit when making such minor changes and how can I get around it? Thanks.

Constantly appending to a string is very inefficient, and may be what is slowing it down. If you still want to use that approach, you may want to look into using a System.Text.StringBuilder, which will allow you to do that, but more efficiently.

When I have Forms authentication for my c# web application, is it possible to run an exe by impersonating the thread with logged in windows user.
At present, when I try to run an exe from the web application, it says "Access is denied".
Is it possible to run the exe without changing the web.config to windows authentication or changing the IIS Settings.
TIA

Make sure EXE is having proper rights i mean a.exe should have all rights for ASPNET account....Try this but i am not 100% sure. We did something very similar to your req in our last year project. Thanks!!

Hi Amit,
The problem is solved. Actually I was able to execute the code without impersonating any user. I had written my process starting code as
1 using (process = Process.Start(psi))<br />
2 {<br />
3
4 }
Application was erring out at line 1. So I thought starting the process needs some permission to the user. Then by chance, I tried commented line 1 and started the process outside without using "using". It worked.
I do not understand why it fails when the process is started in "using".
If you know why using creates problem, do reply.
Thanks for your suggestion!

Hello everyone,
I have created a custom webcontrol that extends from the repeater class and that uses a custom ControlBuilder class for parsing child elements. This is done so that each column in the list can be defined seperately within the .aspx page
Example:
<WebControls:CJIINList runat="server" ID="lstAreaAssignment">
<ListColumn header="Area Designation" datafield="area" type="link" action="ViewDetails.aspx?DocID={0}" actiondata="DocID" />
<ListColumn header="Shift" datafield="shift" type="dropdown" actiondata="1,2,3" />
etc...
</WebControls:CJIINList>
I was able to get this to work, but in the Visual Studio designer, the child elements are all tagged with the following error message:
Validation (XHTML 1.0 Transitional): Element 'listcolumn' is not supported
Is there any way to fix this? Also, I would like intellisense to pop-up the list of properties / attributes available to the ListColumn class like it does for the CJIINList webcontrol.
Any ideas / suggestions would be greatly appreciated...
Thanks!

We need to see code, not screenshots.
How does your page store what tab is selected ? From what you've said, it doesn't sound like it does. If you add an asp:Hidden field in your page, you can store state info there, and viewstate will persist it between postbacks, just read it back in your javascript
Try writing more meaningful subjects, if you could, it really helps us to help you.

Hi Friends,
I have problem sending mail through ASP.Net.
whenever i try to send the mail from my server for which i have passed the details like smtp server and from address , i get an error that :
Mailbox unavailable. The server response was: <myemail@gmail.com> No such user here
But i have specified the from email address of my smtp server.
I have no clue that why is it searching for a gmail address on the smtp server.
I hope i am able to state my question/problem.
Thanks in advance.

What makes you think it's searching for gmail ?

I was debugging the code and after the send mail function it throws an exception.
This is where i got to know it is searching for the other address

I have a script that I can post to via a simple html form, but I can't figure out how to replicate the results with HttpWebRequest. Is there a way of getting the full functionality of a form submit via the HttpWebRequest?
Works:
Does not Work:
ASCIIEncoding encoder = new ASCIIEncoding();
string ifxLoc = "http://script-to-submit-to/login.dll?login";
string postData = "UserName=" + unme;
postData += "&PassWord=" + upswd;
byte[] data = encoder.GetBytes(postData);
HttpWebRequest s2oReq = (HttpWebRequest) WebRequest.Create(ifxLoc);
s2oReq.Method = "POST";
s2oReq.AllowAutoRedirect = true;
s2oReq.ContentType = "application/x-www-form-urlencoded";
s2oReq.ContentLength = data.Length;
Stream s2oStream = s2oReq.GetRequestStream();
s2oStream.Write(data, 0, data.Length);
s2oStream.Close();
Problem:
The HttpWebRequest seems to make a shallow connection to the login.dll, or doesn't fully follow through. I can't get it...working... in any way. It just returns the input of the html of the login page. Am I going about it in the wrong manner?
I also need a way to impliment the native redirect that's built into the simple form submit. If I use a response.redirect() after closing the stream, it is not the same.
Thanks!

Hi,
I have the Gridview which is bound to DataTable. In the GridView I have one button Delete for each row , when clicking on button the row need to be deleted from gridview.
private void BindGrid()
{
GridView1.DataSource = GetDataSource();
GridView1.DataBind();
}
protected System.Data.DataTable GetDataSource()
{
// const string key = "MyDataSource";
System.Data.DataTable aTable = new System.Data.DataTable();
aTable = (System.Data.DataTable)Session["dta"] ;
if (aTable == null)
{
aTable = CreateDataTableA(); -- In this CreateTable I am creating one DataTable and returning it.
Session["dta"] = aTable;
}
return aTable;
}
protected void GridView1_RowDeleting(object sender,GridViewDeleteEventArgs e)
{
int id = Convert.ToInt32( (GridView1.Rows[e.RowIndex].Cells[0].Text.ToString())); -- This statement containg null value always. This is giving exception because of this Null value.
FindRowByID(id).Delete();
BindGrid();
}
private DataRow FindRowByID(int id)
{
DataRow[] rows = GetDataSource().Select("District_ID = " + id.ToString());
return rows[0];
}
How to get the row’s cell value when delete button is clicked.
My Gridview syntax is like this:
<asp:gridview id="GridView1" runat="server" autogeneratecolumns="False" onrowdeleting="GridView1_RowDeleting">
<columns>
<asp:templatefield headertext="District_ID">
<edititemtemplate>
<asp:textbox id="TextBox1" runat="server">
<itemtemplate>
<asp:label id="Label1" runat="server" text="<%# DataBinder.Eval(Container.DataItem, "District_ID") %>" width="115px">
<asp:templatefield headertext="District_Name">
<edititemtemplate>
<asp:textbox id="TextBox2" runat="server">
<itemtemplate>
<asp:label id="Label2" runat="server" text="<%# DataBinder.Eval(Container.DataItem, "District_Name") %>">
<asp:commandfield buttontype="Button" deletetext="-" showdeletebutton="True" showheader="True">
Thanks in advance.

I suggest using an ObjectDataSource as an mediator between the GridView and the DataTable.
ObjectDataSource makes deleting, inserting, updating much easier.
Please read about using the ObjectDataSource an MSDN.
There are also quite a lot samples you can find using google (search terms: GridView ObjectDataSource)
Good luck

I have a site where a user can input the first part of their post code to see if deliveries can be made to their area. Deliveries are only available in one area, so I use the following code:
Private Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click<br />
<br />
Dim al As New ArrayList()<br />
Dim i As Integer<br />
<br />
For i = 1 To 32<br />
al.Add("BS" & i)<br />
Next i<br />
<br />
Dim postCode = Me.txtPostCode.Text<br />
<br />
Dim idx As Integer = al.BinarySearch(postCode, New CaseInsensitiveComparer())<br />
<br />
If idx > 0 - 1 Then<br />
Me.litMsg.Text = "We can collect from you"<br />
Else<br />
Me.litMsg.Text = "We do not collect from your area"<br />
End If<br />
<br />
End Sub
This finds the first postcode, but none of the others. Is there something wrong in the code? Should I just use a database table and pull values from there instead?

Couldn't you use the following if you're only supporting one delivery area:
<br />
<br />
string str = txtPostcode.text;<br />
if (str.StartsWith ("BS"))<br />
...<br />
else<br />
...<br />

Hi Richard, thanks for responding.
I could use the StartsWith method (which works), However, the postcodes range from BS1 to BS32. So if a user types 'BS43' they still get the 'We can collect from you' message.
Any thoughts?
Damian

Put all valid postcodes into an List<string> and use the Contains method:
List<string> postalcodes = new List<string>();
// add all codes
postalcodes.Add("BS1");
...
if (postalcodes.Contains(TextBox.Text))
...
else
...
