I am preparing a site for a school, where student can see answers posted by teacher(s). Page looks (only for this page) will be very much similar to code project, where we can have chain of answers.....
Can i use repeater control for this? I am not sure how i will bind the replies with question if i used repeater control....
But obvious Questions will be display in ItemTemplate...
Any one with any suggestion.....
Thanks,
Amit

To resolve this problem, register the Adodb.dll file in the global assembly cache (GAC). On a computer where only the .NET Framework is installed, the file Gacutil.exe does not exist.. Either obtain the gacutil file by installing Microsoft .NET Framework SDK, or create a Visual Studio.NET setup project that uses the installer to install the correct components.

Both are read-only properties. How are you able to assign the values???

if the item is already existing then check whether whether u are calling these lines
ddlist.SelectedValue=session("name")\\it gives null
ddlist.SelectedItem.Text=session("name")\\\it gives object reference not set to instance of object error.
before the dropdownlist is populated or after!!!
if you are running it before the population then it cannot find the dropdownlist and it will give a null reference exception!!!

Yes, of course. A select query does not change any data.
From MSDN library:
"SqlDataReader.RecordsAffected Property
Gets the number of rows changed, inserted, or deleted by execution of the Transact-SQL statement."

I always thought it should return 0 rather than -1.
|
|
|
|

It's all in the documentation, plain to read: 
"Property Value
The number of rows changed, inserted, or deleted; 0 if no rows were affected or the statement failed; and -1 for SELECT statements."

Well I know that is what it does, but logically it seems 0 would be more appropriate. I'm questioning someones design decision not you answer
|
|
|
|
|
Well, a zero would mean that there were zero records uppdated. As there shouldn't be any updated records, there shouldn't be any count of them either, so I can see how a value representing a non-count would be more appropriate than a count of zero.

Are you actually binding data to it?

If you are not binding anything to it then what's the point in using it??  Just create a HTML table.

 I have make code for file upload on webserver with resume upload, working on local server correctly but not on webserver
try to use codes like this , use 2 text boxes and one button, in first text box write c:\1.dat , in other textbox 2.dat, i.e file from your local harddisk c named 1.dat will copy on the servers folder uploads with name 2.dat, it works well on local server but error occurs on web server
the error is
"Could not find file 'c:\1.dat'. "
you can check this error by using different extension and size files.
By this code, file will not use web servers memory, file will transfers in chunks ( parts ) and append on the server, this is a very usefull thing if somebody want to upload large files in GB.
Please note before answering the problem that lots of FTP softwares available in the market that supports resume upload but on FTP server, not on normal http server as a normal user.
My code are working just like yahoo mail attachment with additional advantage of resume support.
codes are
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
using System;
using System.Data;
using System.Configuration;
using System.Web;

{
FileStream fs = new FileStream(TextBox1.Text, FileMode.Open, FileAccess.Read);
savePath = Path.Combine(Request.PhysicalApplicationPath, ImagesFolder);
saveFile = Path.Combine(savePath, TextBox2.Text);
fs.Seek(this.sentBytes, 0);
byte[] buffer = new byte[bufferSize];
bytesRead = fs.Read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
AppendChunk(buffer, sentBytes, bytesRead);
this.sentBytes += bytesRead;
bytesRead = fs.Read(buffer, 0, bufferSize);
}
fs.Close();
}
public void AppendChunk(byte[] buffer, long offset, int bufferSize)
{
FileStream FSs = new FileStream(saveFile, FileMode.Append);
FSs.Write(buffer, 0, bufferSize);
FSs.Close();
}
}
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
But the codes are not working on real web server.
Thanks
