Hi,
One important thing i noticed was you need to traverse through rows and then cells in tblTimeZon table. And then try to find the control in a particular cell.
Here is a small example, i will be using a TextBox.
.aspx code
<asp:Table ID="Table1" runat="server" Height="160px" Width="176px">
<asp:TableRow runat="server" ID="ROW1">
<asp:TableCell runat="server" ID="CELL1">
aaa
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</asp:TableCell>
<asp:TableCell runat="server">bbb</asp:TableCell>
<asp:TableCell runat="server">ccc</asp:TableCell>
</asp:TableRow>
</asp:Table>
<asp:Button ID="Button1" runat="server" Text="Get Content in Text" OnClick="Button1_Click" />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
.cs code
protected void Button1_Click(object sender, EventArgs e)
{
foreach (TableRow tr in Table1.Rows)
{
foreach (TableCell tc in tr.Cells)
{
TextBox tb = (TextBox)tc.FindControl("TextBox1");
if(tb != null)
{
Label1.Text = tb.Text;
}
}
}
}
Hope it helped.
Thx,
Gayani

Hi All,
I've a image gallery website where members can upload and restrict the access to few friends. The problem is, images are directly accessible from browser. How could I restrict specific folder to accessible from aspx pages only.

I have done similar to this..
I have used a webservice to get the path of the requested images from an encrypted session guid which is created during login...

Thanks for the reply. When I show image, anybody can check the relative path from viewsource and try other photos from same folder. Please correct me if I'm wrong or I understood your reply wrongly.

Write a http handler which handles requests for images. Check the authentication and display necessary messages. Make sure you map the extensions to ASP.NET in IIS settings.

Thanks for reply but I'm not aware how to write this type of handler. Could you help me for a sample.

There are two ways of doing this - an easy "hack" and a "proper" way...
The easy way is simply to save your images with randomly assigned (GUID-type thing) filenames which can't be guessed. This doesn't stop people linking directly to your images once they know the filename of course, but unless your images are highly popular that is unlikely to be a problem, but it will stop them from finding images until you reveal the address.
The proper way is to write a custom handler; you can find an example here[^]. Note though that depending on your version of IIS you may need to perform some steps differently - that article assumes IIS6; once you get above this you need to write your config file differntly, for one thing...

Webapplications are not suitable for what you are trying to do. Consider changing your design.

I am using COM DLL (Which is developed in VB) in .Net to fill the Schools Name in Dropdown list but it is not filling (it is giving this error: Server Threw an Exception: RPC_E_SERVERFAULT’). In development machine it is working fine and we have another product which is not using this COM DLL that application also working fine. It seems COM DLL having some issue with Network Path
Our Product installed in Windows 2003, which is running IIS 6.0 in the same machine but our Data (Contains collection of Files) is other machine (Jai-XP PC). Both the machines are connected under one
Domain controller.
In IIS under Directory Security I gave domain user ID and password and i gave the same user for data also.
How we can solve Interop services in domain controller environment.
I hope somebody will resolve...
Thanks & Regards,
Jai Sankar N.
