Hello
I am writing a Desktop application accessing a SSCE database. I am running Windows XP SP2, VS2005 SP1, and have SQLServerCE3.1 installed. Debugging the application shows that ds.m_spInit->QueryInterface() returns E_NOINTERFACE. I have checked that SSCE runtime library is installed, IDBCreateSession uuid exists in the registry and m_spInit.CoCreateInstance(CLSID_SQLSERVERCE_3_0) return S_OK. Can you suggest me what need adding/installing to get the CSession.Open(datasource) working?
Thanks

Hi,
For some reason I can't use the edit, update or insert features on my remote shared server, so I am looking to create a web page that has text boxes on it, that I can enter data into, that will be saved into my database.
This is opposed to entering the data directly into the database itself. I want to be able to use a webpage, for simply adding new data, and saving it so that the new data updates and saves over the top of the old data.
What are the steps involved in doing this?
Any example code for just one text box would be appreciated, I could then extend it to suit my needs. Tia.

Hi,
i have a richtextbox control in my application, and want to know how to save and retrieve formatted text in a MS SQL DB.
I found this example in the forum, but I don't know how to use it. Can you please help me solve the problem? Where should I write the code below?
I've just tried it and able to do this successfully.
I basically did this:
load the RTF into the RTB control
created a SQL command, simple basic insert statement:
SqlCommand theSQLCommand = new SqlCommand("INSERT INTO [TableName] (Field) VALUES (@p1)");
SqlParameter theSQLParameter = new SqlParameter("@p1", SqlDbType.Text);
theSQLParameter.Value = this.theRichTextBox.RTF;
theSQLCommand.Parameters.Add(theSQLParameter);
theSQLCommand.Connection = new SqlConnection(ConnectionString);
theSQLCommand.Connection.Open();
theSQLCommand.ExecuteNonQuery();
theSQLCommand.Connection.Close();
then to retrieve it, I did this, again, specifically for this example
this.theRichTextBox.Text = String.Empty;
SqlCommand theSQLCommand = new SqlCommand("SELECT [Field] FROM [TableName] WHERE [ID] = 1");
theSQLCommand.Connection = new SqlConnection(ConnectionString);
theSQLCommand.Connection.Open();
SqlDataReader theReader = theSQLCommand.ExecuteReader(CommandBehavior.CloseConnection);
while (theReader.Read())
{
this.theRichTextBox.RTF = theReader.GetValue(0).ToString();
}
theSQLCommand.Connection.Close();
And was able to do this fine and got all the formatting etc... correctly.

Hello,
I am working on a ASP.NET 2.0 project with an SQL 2005 database.
I created a documents table with various columns including:
DocumentId and DocumentUrl
My documents will always be PDF's of SWF's (Flash Paper Files)
I will need to display this files in my web pages.
My question is:
Should I save the DocumentUrl in the database or should I save the file itself in the database?
And how can I save files in an SQL 2005 database?
Thanks,
Miguel

Database Connection - Don't have permission to open file
I'm trying to establish a connection to a database file (c: empMine.mdf) through visual studio c# express 2005 edition.
I'm using the database explorer/add connection wizard.
On the add connection dialog window when i browse and select the db file to connect to i'm getting the message
"You don't have permission to open this file. Contact the file owner or an administrator to obtain permission"
I have SQL Server Express 2005 and SQL Server Management Studio Express installed.
Within the management studio at the server security level i'm mapped to the db file
(Mine.mdf) and have db_owner and public ticked and have also set the default database
as Mine
At the database security level under usersproperties i have also ticked db_owner.
Also when i select properties for the db file itself it's telling me that i'm the owner.
I'm also using vista home premium edition and using windows authentication instead of
sql server authentication.
I'm fairly new to all this so there may be something glaringly obvious i've missed!
Thanks.

I have a SQL Server 2005 database file (a .mdf file) that I am trying to open in SQL Server Management Studio so I can add a field to a table, but I am unable to open the file. I can't say that I really understand how SQL Server handles these databases. I especially don't understand the "attaching" and "detaching" operations.
I am working in VB.Net 2008 now, but my background is with VB6 using the JET engine. It was just so straightforward using the JET engine, but seems so much more complicated with SQL Server. I am trying to use .mdf files the same way I used .mdb files. I want my application to find the database file, "attach to it", and let me manipulate it.
At one time I was able to open my database in Sql Server Management Studio and edit the design of the database. The application still works but I am no longer able to modify the database because I cannot attach to it in Management Studio.
Here is a big clue: the files are no longer in the special folder anymore, which is c:Program Files (x86)Microsoft SQL ServerMSSQL.2MSSQLDATA. I might have deleted the files, stupidly, thinking they were redundant. I still have the .mdf file (and the _log.ldf file) on my hard drive and the application can still open it, but when I try to use Management Studio to attach to the .mdf file, I get this error:
Microsoft SQL Server Management Studio Express
An error occurred when attaching the database(s). Click the hyperlink in the Message column for details.
here are the details:
Unable to open the physical file "c:Program Files (x86)Microsoft SQL ServerMSSQL.2MSSQLDATAHEALSExamsSQL.mdf". Operating system error 2: "2(The system cannot find the file specified.)". (.Net SqlClient Data Provider)
Indeed the file is not there, but why is Mgmt Studio looking there? Why doesn't it just open the file where it is? What can I do to get it back? I even copied the files to c:Program Files (x86)Microsoft SQL ServerMSSQL.2MSSQLDATA? I get the same error.
Here is another clue: In Management Studio, when I right-click Databases, and chose Attach, it brings up a dialog. There I click "Add" to get another dialog in which I will select a database, but before the dialog appears I get this error:
Locate Database Files - KURANT-WIN7SQLEXPRESS
C:UsersJason KurantDesktop
Cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists.
If you know that the service account can access a specific file, type in the full path for the file in the File Name control in the Locate dialog box.

I successfully upsized an Access database to SQL Server Express so that I have an Access frontend and a SQL Server Express backend. People started using this on an intranet, but right away they started complaining that sometimes their data wasn't saved. For example, they might have entered 8 records but when they went back to look at them only 4 were actually saved in the database. Any idea why this might be, or how I could trace the errors and find out?

I'm working on a report to show financial transactions from a table over a certain period. For most transactions there is a PDF document that is stored in a separate table in a binairy format. In my report I would like to include a link on every line with transaction information in the report that opens the PDF that is linked to that transaction. Just to be clear, I don't want to embed the PDF in the report but I want the users of the report to have the option to view the PDF that is related to that transaction in their standard pdf reader (adobe).
Code to do the following:
Once a user clicks on the link to view the PDF I need the code to get the binairy data of the PDF file from the table, convert it back to a PDF and open it in the default pdf reader (for example adobe reader). If it can't directly open the file then it's maybe possible to activate the 'open or download' pop up that you also get when you download something from a website.

I get the below error only when my IDE open. It connects well when it is found closed.

I could solve this by giving the logged in windows user to impersonate under IIS window > WEBSITE > ASP.NET tab > EDIT CONFIG > APPLICATION tab
But I wish someone could give me the proper solution.
I almost tried all from giving ASPNET user as a administrator to configuring the same in Express management tool.
