Which line throws the exception? The exception should also give you more information that just sql exception. When you catch the exception what other information does the exception variable have?

SetStyle is inherited from Control so will work with all classes derived from Control at some point, so Panel yes, other controls almost certainly yes.

mycmd.Parameters.Add(expeditorp);
SqlParameter destinatar1p=new SqlParameter ("@destinatar", SqlDbType.VarChar, 5);
destinatar1p.Direction=ParameterDirection.Input;
destinatar1p.Value = dgdest.Items[0].FindControl("lbldest"); <- Problemns
mycmd.Parameters.Add(destinatar1p);

Hi everyone,
______ 1 _______
| |<----------->| |
| | 2 | |
|______|<----------->|_______|
Client machine Web Service
Webmethod 1 and Webmethod 2 are being called here.
I want to make both happened in a single transaction.i.e "1" also should rollback if "2" has failed.
I can't open a connection object in the client.Its been opened in the webservice.
1
|<----------> [webmethod A (Transaction) ]
client app | 2
|<----------> [webmethod B (Transaction) ]
Here after 1 the transaction will be over in normal scenarios ,which should not happen
How do I achieve this.
Thanks in advance

if I drag an Outlook.MailItem to a Windows-Explorer window a
<subject>.msg file will be created.
Now I try to drag & drop a mail item to my own WinForm app.
Unfortunately it doesn't work.
Any ideas?

Standard question #1:
What do you mean by "not working"?
You have to enable drag-and-drop for the controls in your form that should recieve them. Then you implement the events that handles it.
---
b { font-weight: normal; }

When I drag a mail from outlook to MSWord an attachment will displyed in MSWord. I need the same thing in C# application.
Thanks

Sometimes it feels like someone replying to a post of mine didn't read my post at all. This is one of those times.

So, in your C# application, set the necessary control to handle the drag-in-drop.

Hi,
I want to dynamically load some assemblies and invoke certain functions given in those assemblies. All these functions will implement the same interface, so that I don't have to bear the performance hit of a Type.InvokeMember call. For loading these assemblies dynamically I will, obviously, have to use the Assembly.Load/LoadFrom routines.
My question is, is it advisable to put some assemblies (which may be dynamically loaded frequently) into the GAC or have some sort of a replacement algorithm (like LRU) to add and remove these assemblies from the GAC ? Also, if I put these assemblies into the GAC, will the Assembly.Load/LoadFrom routines check the GAC first while searching for the assembly or will I have to query the GAC to find whether the requested assembly exists in the GAC or not and then proceed?
Thanks for any thoughts or help.
Cheers

How to sort contents of datatable using one or more columns and assign the sorted contents to Data Grid.

You need to use DataView[^] class to sort the contents of a DataTable.
And then use the DataView as the DataSource to your DataGrid.
