SqlClient is optimized for SQL Server, so if you're using SQL Server (and you should) use SqlClient.
Use OleDb if you're using Access (you shouldn't).
MySql, Oracle, and Ingres (and others?) have their own classes, use them as appropriate.
Now stop cross-posting.

HI Friends,
I am trying to match the value from database with checkbox list items and if matched I want to check the checkbox:
if(chklstGroups.Items[i].ToString() == objGroups.Title)
{
chklstGroups.SetItemChecked(i,true); // Method 1 -- Generates Error
chklstGroups.SelectedValue = i; // Method 2 -- No Error but no result.
chklstGroups.SetSelected(i,true); // Method 3 -- No Error but no result.
break;
}
Please help me if you know the solution.
Regards,
Sushant Duggal.

Wouldn't it be something like:
chklstGroups.Items[i].Checked=true;?
The day has been too long, I've spent frittered too much time on here today, I need sleep.

This worked for me:
this.checkedListBox1.SetItemChecked(0,true) ;

Object reference not set.

Then I suppose your chklstGroups hasn't been set.
Show more of the code.

Use debugger to check whether the "if" statement evaluates to true
by creating breakpoint at a line inside the if block.

I no longer use CheckedListBoxes, I use TreeViews that look like CheckedListBoxes; they're much more advanced.

try this:
if( (objGroups.Title != null || objGroups.Title != DBNull) && chklstGroups.Items[i].ToString() == objGroups.Title.ToString())
{
chklstGroups.SetItemChecked(i,true); // Method 1 -- Generates Error
chklstGroups.SelectedValue = i; // Method 2 -- No Error but no result.
chklstGroups.SetSelected(i,true); // Method 3 -- No Error but no result.
break;
}
Hope it helps...

Try the following.
//Add these namespaces to your page.
using System.IO;
using System.Security.AccessControl;
using System.Security.Principal;
//Put this code in either Page_Load or any other function
string DirectoryName = @"C:\Test"; //Make sure the directory exists.
string Account = @"Domain\username"; //Replace it with your Domain Name and User Name.
DirectoryInfo dInfo = new DirectoryInfo(DirectoryName);
DirectorySecurity dSecurity = dInfo.GetAccessControl();
dSecurity.AddAccessRule(new FileSystemAccessRule(Account, FileSystemRights.FullControl, AccessControlType.Allow));
dInfo.SetAccessControl(dSecurity);
Hope it helps!

Hi,
How can i limit the bandwidth for a webrequest using Httpwebrequst.
If i am having network connection say 100Mbps, if i want to limit the
bandwidth to 75MBPs, How can i do this in WebRequest.
With Thanks,
Sakthi.

You can't. There is no facility to do this anywhere in the .NET Framework. You'd have to write your own network stack to control this, or use a proxy server that offers this functionality.

Hi CLRers,
I have one doubt regarding usage of the reflection to get the
private member variables. In one of my assembly through reflection
i am getting private member variables in the same assembly classes.Client can change the Code Access policy to restrict the private member variable right?
Client can only restrict to accessing only private members or any members can restrict?.
if yes than what is the use of reflection...
So usage of reflection in projects how much safe .......? and Reflection is usefull in Unit test drivers only or wht?
Please help in this regard ....

Have look at NUnit source code 
|
|
|
|
|
Still it is not answered my question...
Through reflection how much safe to access private members ?
It is violating OOPs concepts..

It is not safe because you try to access methods at run time using "reflection".
Use SecurityPermissionAttributes on your private methods for which you want to access.
What is the reason behind accessing a private mthod. Do it public then.
As a design rule, make things non-punlic if you don't neeed them or if you want to secure them.
Have alook at .NET Reflector tool which disassembles any .NET assembly to it's original source code using reflection including of course the private ones. Which means you can access but this tool also shows how unsecure your private methods are. To call these methods, I've not tried actually but as I said, try to make them internal or private and add SecurityAttributes to ptotect.
Hope this helps...
