I think it requires adding code to update the data table adapter.

Thanx but i already have this:
<br />
this.Validate();<br />
this.pROFILEBindingSource.EndEdit();<br />
this.pROFILETableAdapter.Update(this.dataSet1.PROFILE);<br />
it's just not working

and i want to share it in the forum for those who may run into the same stupid problem!!
invalid host/bind name was because i used the keyword "DESC" as a field name in the table im referencing in the database, it was stupid cuz oracle accepted it very well!! so i thought it's fine to name a field with a keyword but not the table, and what's more, it binds normally to the control when loading "which means the field name is only fine for reading!" but when trying to launch the adapter.update(dataset) you get this wonderful error that has nothing to do with the real problem!! i'v always hated oracle's error messages cuz they never lead me to the cause of the error!
cheers

That depends on your network. However, you can see examples of connection strings here[^] that should help you create the correct connection string.

I don't understand what you mean. Do you want to add a column to the view that does not exist already in a table? If yes, then you can only add computed columns. The view contains no data whatsoever, it can only link to existing data therefore any column on the view must be exsting data or derived from existing data.

This is not possible in SQL Server 2000. It may be possible in SQL Server 2005, but I doubt it. Certainly you could use CLR stored procedures to encrypt and decrypt data, however doing so on key or indexed columns is not advisable because it will dramatically hurt the performance of your database.

You need to supply more information. Did you change anything between yesterday and today?

I have a database and a form. When I load the form, the database will get converted into an XML file and will get displayed in my form. If I change some values in the xml which is displayed in my form, those changes should get reflected in my datagrid(which shows the contents of the database) and also in my database. So far, I can update the datagrid but not the database. How can I do this? Any kind of help would be sure appreciated.

In the 12 years ive been developing software ive never been so stumped on one issue for so long...
I took over the design of the companies web application from my boss.
I tidied up 75% of the code and now have a pretty tidy way of doing things as follows...
each page inherits a page called 'basePage', this has all the necessary functions in it for data manipulation, such as...
<br />
GetConnection() as SqlConnection (returns it unopened but populated with the connection string)<br />
GetDataTable(sql as string) as DataTable<br />
ExecuteQuery(sql as string) as integer<br />
etc...<br />
Recently we started getting "Timeout Expired" errors "while obtaining a connection from the pool".
Ive tried various extremities of parameters in the connection string such as "min pool size=5;max pool size=1000;connect timeout=90;". and have read numerous articles on the subject.
I have also turned off connection pooling entirely and still receive the same error (differing only by not mentioning "the pool").
Before you ask - yes, i am using try catch blocks in my basepage functions and always closing and disposing my objects in the finally block.
Today i received no less than 840 timeout error reports on the server in one hour - there was only 46 people using the application at the most within that hour.
The timeouts seem to happen all at once for a few minutes, like a big bottleneck. The server itself was running fine - not even brushing 50% cpu usage. But the web application itself would slow down quite badly, taking up to a minute to serve the page.
I set up some tracing and noticed that some pages made no less than 60 calls per page load to the GetConnection() method 
This is due to various business objects being called and checking data etc...
Before i even suggest that any of the business model be redesigned, id like to ask.. has anyone ever come across this type of situation before?
are most of you spitting coffee on your monitor over the 60 page calls like i nearly did? 
or have you seen this before in big applications with many components?
Any help, comments or suggestions are welcomed.
Regards,
Guy

Is the code closing the connection before getting another?
Guy Harwood wrote: are most of you spitting coffee on your monitor over the 60 page calls like i nearly did?
You might want to see if you can rationalise some of these calls. For example, if you alwasy call the same three stored procedures in sucession then you might be able to create a wrapper stored procedure that calls the other three so you can only doing one call to the database. You can then iterate over the result sets and pull out multiple sets of data from one database call. (If you are using DataReaders the NextResult() method is the one that moves to the next result set)
The thing that causes the most slow down in an application is roundtrips to the database. If you can reduce the number of roundtrips it would improve performance, and reduce the number of connections you are making.
I'll also admit that I've never had to alter the timeout of the connection from the 15 second default.
By the way, what edition of SQL Server are you using?

Hi Colin,
Yes the code always closes the connection before getting another.
Ive used the nextresult() stuff before, very handy and will come in useful when i end up knocking down those 60 calls per page load!
We are using SQL Server 2000 with SP4 on 2003 server.
The server has 3GB ram and 2 Xeon 2.4GHZ processors (effectively 4 cpus according to sql server).
I did notice something odd in the event viewer application log earlier that was entered right about the time the errors started pouring in...
Error: 15457, Severity: 0, State: 1
Configuration option 'show advanced options' changed from 1 to 1. Run the RECONFIGURE statement to install.
wasnt doing any maintenance and never seen it before.

If you Google “SQL Server 15457” there are quite a number of hits, would seem error code 15457 is an informational error code, but most of the people posing questions about this error code have the same issues you’re experiencing. Most of the issues seem to be related to the db getting locked or query time out values changed. Might want to take a look.
