hello
I am using Sql server 2000 and .Net 2005 i am suffering from the connection problem ,error are.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I have Already Enabled Tcp/IP And Named Pipes in Network utility of sql server.
Please Help

Have you fixed this problem? If not, look in the Surface Configuration tool...

Use a connection string, here is a useful site: http://www.connectionstrings.com[^]

create a SQLConnection object
assign a connection string to the connection object's connection string property
say ConnectionObject.Open();
now u r connected
use this connection object in your command object to run commands in the database

Hi, I have 3 tables, here is the .sql file, just copy and paste starts from the line :

-- ENDS HERE --
I Use MySQL Administrator
When I tried to make a foreign key in table ITEM_LOCATION.
Field "Item ID" will be connected with "Item ID" in table ITEM_GENERAL, with RESTRICT on DELETE and CASCADE on UPDATE.
The problem is, I kept getting this message :
MySQL Error Number 1005
Can't create table 'myDbName\#sql-610-122.frm' (errno 150)
I have another Database with tables like above, but I got no problems when creating foreign key. It's only in the above tables the problem is on.
I just hope it's not a bug...
Any Helps? Thanks.
Enjoy It!

Is the underlined part correct? defaults to an empty string?

Well, I made the tables more simpler:
-- ------------
CREATE DATABASE qwe;
USE qwe;
DROP TABLE IF EXISTS `gudang_list`;
CREATE TABLE `gudang_list` (
`Gudang ID` varchar(15) character set latin1 NOT NULL default 'GA-001',
`Description` varchar(50) character set latin1 NOT NULL default 'Gudang Atas',
PRIMARY KEY (`Gudang ID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;
DROP TABLE IF EXISTS `item_general`;
CREATE TABLE `item_general` (
`Item ID` varchar(15) character set latin1 NOT NULL default 'KOM-001',
`Description` varchar(50) character set latin1 NOT NULL default 'KOMPUTER',
PRIMARY KEY (`Item ID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;
DROP TABLE IF EXISTS `item_location`;
CREATE TABLE `item_location` (
`Item ID` varchar(15) collate latin1_general_ci NOT NULL default '',
`Gudang ID` varchar(15) collate latin1_general_ci NOT NULL default '',
PRIMARY KEY (`Item ID`,`Gudang ID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;
-- -------------------------
This produces the same error... and I suspect the CHARSET and COLLATE play something about the error..
Just import it using MySQL Administrator.

Hi again, I changed the CHARSET and COLLATE to utf8 and to utf8_general_ci
It works!
But I just confused how the difference between those CHARSETS and COLLATIONS ?
Enjoy It!

Dim dIndex As Integer
Dim dCount As Integer
dCount = Me.dataGrid1.SelectedRows.Count
If dCount = 1 Then
dIndex = Me.datagrid1.Rows.GetFirstRow(DataGridViewElementStates.Selected)
myBusTier.bDeleteData(dIndex)
Me.DataSet1.AcceptChanges()
Me.TableAdapter.Fill(Me.DataSet1.myTable)
ElseIf dCount <= 1 Then

It is a warning that there is a replacement technology that you should consider using because CDaoDatabase will be getting removed in a future version of MFC.
You may wish to consider reading the current documentation for MFC in the area of databases, it will most likely tell you what should should be migrating towards.

I'm not sure about CDaoDatabase being removed in a future version of MFC, but I know that DAO is not being ported to 64-bit. That is, I believe the 32-bit runtime is still present for a 32-bit application, but there will be no 64-bit runtime. As such, CDaoDatabase will no longer work if you recompile your application for 64-bit.
Microsoft considers DAO obsolete[^].

Ah, well. I knew something had to be going. If the underlying technology is going, then there is no need for the CDao... classes.

then there is no need for the CDao... classes.
then what is the update replacement for CDao in MFC? any references?

Sorry, it has been several years since I used MFC.

i have created a database in sql server7.0 and now i have generated the script from sqlserver 7.0 and i have installed sql serve 8.0
if i connect the database to vb.net i got the answer lik this not associated with trusted trusted sql server connection how do mim clear the error

The SQL Server does not regocnise the windows account you are using. You need to setup the appropriate windows login on the SQL Server, and then associate it to the appropriate user in the individual databases.

we have formatted our system and we have installed sql server 2000 version 8.0
previously we have developed using version 7.0 and i have done above still i got the error like that

Have you tried what I asked? What have you done to "setup the appropriate windows login on the SQL Server, and then associate it to the appropriate user in the individual databases."?
|
|
|
|
|
where i a have to setup the appropriate windows login on sql server
|
|
|
|

In SQL Server. I'm sure you'll find it in the SQL Management Studio - In the Security or Logins section (I don't have SQL Server 2005 on this machine so I can't tell you exactly right now)
|
|
|
|
|
i found that if i change that one also but i got the same error .if i change my database from sql version 7.0 to sql version 8.0 if it work or else we have to change the coding in vb.net side
|
|
|
|
|
Sorry - Got confused. (People don't normally talk about version 8.0 and for some reason I thought you were talking about SQL Server 2005)
To set up the logins and users go into the Enterprise Manager and open your server in the tree on the left, open the Security folder and select Logins. From here you can set up the logins.
In the individual database, find the Users area and connect the login to the database user.
