Hi,
Does anyone know how I can connect to an MSDE db using VB with a
read-only file? The file will be on a CD, and is actually just archived
data off a SQL server. I would like to package my app on a CD along
with the data file and allow users to pop in the CD and run the app,
assuming they already have MSDE running. Any help?
Thanks,
Jason

I posted this as a reply to another thread but then noticed it was marked as 'Answered' so i figured I'll create a new one.
This is a known issue (i guess) that you need to have write access to the database your connecting to but I actually want to know how to connect to a database with read only permissions. This should not be that rare of a case where you only want to read something without writting to it. I have a system where users can connect to other databases and "import" data from there but if the user doesn't have write access or the file is read only I get an exception.
Any idea how I can connect in read-only mode?
Thanks!
G'day,
I'm very new to ASP.NET (but not to programming) and I'm having some trouble with connecting to a database.
I am using C#.NET and I dragged the SqlConnection component onto the form, set the connection string to (local) and to use integrated security, and on that data link properties page I can press the test connection and it works fine, and I can see the databases in "select database on server" drop down box... but when I try and Open() the connection I get a
Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'AMD2500ASPNET'.
Can anyone help me?
Thanks,
Robbo
I am trying to connect to a MSDE database on server from my desktop using query analyzer. I keep getting the generic "SQL Server does not exist or access denied'
I have verified the following:
- the login/password is valid because when I access osql from server I can gain access
- the registry for Loginmode appears OK - set to 2 - mixed mode
What else do I need to check...
Thanks, kgaske
Being new to the SQL server world I have a beginner question.How do I grant access to database from a networked computer?I have tried:sp_grantlogin '\computernameusername'and I get the error:Windows NT or user <above> not found. Please check name.Any help would be appreciated.ThanksEric
View 1 Replies View RelatedPlease advise: I have created a simple ASPX page to test if I can connect to MSDE on a Server 2003 system. The connection string that works ok is:
server=WS1;database=northwind;integrated security=false;user id=sa;password=xxx;
but the string that does not work is:
server=WS1;database=northwind;integrated security=SSPI;
which is the string I would like to use for normal web access. This string works fine on my development system (where I use XP Pro and IIS 5.1)
In IIS6 on the "production server" the directory security on the virtual dir is set to allow anonymous access, using user IUSR_WS1 (where WS1 is the name of the system) and to integrated security.
Please help! Thank you

View 2 Replies View RelatedHey guys, I am a newbie here, so please bear with me. I have installed SQL Server 2005 CTP on Machine A and MSDE on Machine B. Both these contain the PUBS database beside others. On Machine C, I have installed "ASP.Net Web Matrix" and I want to be able to connect to either Machine A or B to access the PUBS database. It connects to Machine B, when I put in the Servers IP address. But everytime I try to connect to Machine A, it gives me an error saying, "Unable to connect to the database. To connect to this server you must use SQL Server Management Studio or SQL Server Management objects(SMO) ". I heard that connection strings are needed to access the SQL Server 2005 but I have no idea where to begin. Do I need to create special users to access the Server or will Windows authentication work ? Could anyone help me out in connecting to the SQL Server 2005 CTP?

I have installed MSDE into my system, in which SQL Server is not installed. I have followed the installation instructions and installed MSDE.
How can i connect to the database? I have the .MDF file of the database (already created in sqlserver) in the Data Folder. How can i connect to the database from Visual Basic 6?
Hello,
I have downloaded WebMatrix/NET.Framework and it works well.
Unfortunatelly I have problem with connecting to MSDE.
I've installed the new version (sql2ksp3a) like they say:
setup.exe INSTANCENAME=my_inst_name DISABLENETWORKPROTOCOLS=0 SAPWD=my_pass
SECURITYMODE=SQL
The MSDE works ok (I can connect from a commercial programs - for example
'MSDE Manager') and seems to be ok.
But when I try to connect from Web Matrix I get the error:
"Unable to connect to database, Invalid connection connection Open, Invalid
instancename".
I put all the parameters correct:
user: sa, auth.type: SQL, server: my_pc_namemy_instance_name
By the way the instance name and my PC name is the same. Could it be the
reason ?
Please help,
greetings to all

Hi!
I have installed MSDE 2000 in "Mixed Windows and SQL mode authentication with network access" .following is the command:
setup.exe DISABLENETWORKPROTOCOLS=0 SAPWD="password" INSTANCENAME="TempInstance" SECURITYMODE=SQL
Then I created the database TempDB in it.
When I try to connect this database from my program running on my machine , it works fine. But when i try to connect to it from the same program running on a different machine on the same domain.It gives error:
"SQL Server does not exist or access denied ."
Even when i run the same program in my machine to access the same TempDB database on a remote machine that is not in my domain, it works fine.
this is my connection string:
Data Source={Database server's IP Address}TempInstance;Initial Catalog=TempDB;User ID=sa;PWD=password;
Please help.

Hi,
I'm trying to connect to an instance of MSDE 2000 from Visual Studio 2005 over a home network. Although I know how to connect to a database from Visual Studio, I'm pretty clueless about configuring Sql Server to allow the connection (I can connect with no problem when I do so from the same computer). Also, with experimenting I've created a bunch of instances of Sql Server that I don't really need and am not sure how to get rid of them. Thanks in advance for any help.
-Dave
I don't know if this will help, but I've already tried enabling all of the network protocols in the instance. Also, I can easily connect to an Access database over the network.
Hello Experts,
I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle).
PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not..
What should go here ?
->Under Class A
public override DTSExecResult Execute(Connections connections, VariableDispenser variableDispenser, IDTSComponentEvents componentEvents, IDTSLogging log, object transaction)
{
//Some code to read file and write it into new file
return DTSExecResult.Success;
}
public const string Property_Task = "CustomErrorControl";
public const string Property_SourceConnection = "SourceConnection";
public void LoadFromXML(XmlElement node, IDTSInfoEvents infoEvents)
{
if (node.Name != Property_Task)
{
throw new Exception(String.Format("Invalid task element '{0}' in LoadFromXML.", node.Name));
}
else
{
try
{
_sourceConnectionId = node.Attributes.GetNamedItem(Property_SourceConnection).Value;
}
catch (Exception ex)
{
infoEvents.FireError(0, "LoadFromXML", ex.Message, "", 0);
}
}
}
public void SaveToXML(XmlDocument doc, IDTSInfoEvents infoEvents)
{
try
{
// // Create Task Element
XmlElement taskElement = doc.CreateElement("", Property_Task, "");
doc.AppendChild(taskElement);
// // Save source FileConnection
XmlAttribute sourcefileAttribute = doc.CreateAttribute(Property_SourceConnection);
sourcefileAttribute.Value = _sourceConnectionId;
taskElement.Attributes.Append(sourcefileAttribute);
}
catch (Exception ex)
{
infoEvents.FireError(0, "SaveXML", ex.Message, "", 0);
}
}
In UI Class there is OK Click event.
private void btnOK_Click(object sender, EventArgs e)
{
try
{
_taskHost.Properties[CustomErrorControl.Property_SourceConnection].SetValue(_taskHost, propertyGrid1.Text);
btnOK.DialogResult = DialogResult.OK;
}
catch (Exception ex)

Console.WriteLine(ex);

I have a filetable that contains a binary file. I need to do a selective read of the file stored in the file table. I can write a C# CLR function that will open the file, read n bytes the from a starting byte. Or I can write a SQL statement that reads the stream in the filetable into a VARBINARY variable using SUBSTRING beginning at the starting byte (offset from 1) for the same n bytes.
Both give me the same result. However, the SQL statement takes considerably longer to read. I know there is overhead in reading through SQL (interpreted language), but the difference in performance is substantial, and I can only attribute this performance degradation if SQL first tries to "load" the entire stream before it identifies the portion of the stream that it needs to read beginning at the starting byte offset.
I wonder if this is the case or if there is another option to read a stream from a filetable directly through SQL queries that is more efficient.

Anyone reading XML disk-files into SQL Server?
I have a process that I may want to do this with.
It would be a stored procedure that would read the XML attributes into 2 tables, the number of attributes could be 1-N, so I thought XML would be a good choice. Also, one of the attributes could be up to 4000 characters. I think this may limit our options, can 100-150 4000 character strings be passed in a standard call to a query/proc in SQL?
Currently the client application makes round-trip network calls to save upwards of 100 pairs of data. 1 header row, and many detail rows. All within a transaction.
I think If we move an XML file to the SQL box, then do all the import/save work on the "Server" side it would be much better. Cutting the transaction time down a lot by not doing so many round-trips at network speed...
Thoughts?
Any one can help me how to read a file(.txt) with in the store procedure?

Hi All
I am trying to load DBF files into SQL server within CLR (actually if just running the select statement outside, say within the SQLQuery window, i got the same result), but with the following error:
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "VFPOLEDB" for linked server "MYDBF" does not contain the table "T8866064". The table either does not exist or the current user does not have permissions on that table.
I created the linked server in this way
EXEC sp_addlinkedserver
@server = 'MYDBF',
@provider = 'VFPOLEDB',
@srvproduct = 'My Data',
@datasrc = 'c:data'
i did not create the login since my SQL instance is running under a superaccount with all privilege.
What frustrates me is that i can read most of the dbf files, but just a few of them is not readable.
Can anyone give me some hints on it?
by the way, i am using vfp9.0
thanks

hi
how can i read a txt file by using T-SQL commands.
thanx
How can I read one external file (*.txt,*.csv) through
stored procedure in MS Sql Server 2000 ?
On the database Interbase its very simple :
[CREATE TABLE table [EXTERNAL [FILE] <filespec>]
( <col_def> [, <col_def> | <tconstraint>
]);
EXTERNAL [FILE]<filespec>
Declares that data for the table under creation resides
in a table or file outside the database;
<filespec> is the complete file specification of the
external file or table]
Please advice
Thanks
