Maybe it's not correct question... Does all new EF 4.0 features will
work with FbClient 2.5 ?

Does provider fit to work with EF 4.0

2009-12-08T01:48:28Z

Hi. I've tried VS 2010 Beta 2 - very nice emotions. There are many
useful features in EF 4.0, such aa lazy loading, cascade deleting,
foreign keys and many other.

I palan to start new project, but i don't like MS SQL. Is it possible to
use FbClient 2.5 with new version of .NET Framework, or i i should wait
for a new version and use MS SQL now?

GAC Name: FirebirdSql.Data.Firebird.Client Version: 2.5.1 PKT: 3750abcc3150b00c

Entries in machine.config from C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG.

<configSections>
...

<DbProviderFactories>
...

Do you see something wrong there? I should also mention as I have a few times now. I can see the database through the server explorer and can use the dataset design tools, but I can't add a an Entity data model because I don't see firebird as a connection option.

Obviously not. Else it will be available as DDEX and EF connection.
Check what you have in GAC and what version you're using in
machine.config.

Re: VS to Firebird

Dear Will,

try this link http://codemuch.com/node/3

hope this will solve your problem...

2009/11/21 Will Ferguson <willferguson@...>

If I knew how to do it I’d gladly contribute and write the instructions.

I didn’t get the firebird Database for free. It was foisted upon me by a third party Software program the company uses.

I want to integrate the business processes. We have SQL, JADE and Firebird Databases that need to “talk” with each other . So I’ll need to access 2 Firebird Databases.

Read access is fine. I don’t own the data structure but I do own the data.

I’m not complaining because something has gone bad. I’m complaining because nothing has gone right.

Nothing personal guys. Firebird is a great product. I’m just frustrated I can’t work with it in VS yet.

Surely there is someone out there that can. And is willing to help me understand where I’m going wrong.

It may be that this is a VS problem not a firebird problem.

PS. I do a lot of work for charity. I contribute to user groups all over the world. I am not looking for a free ride , nor am I lazy. I am a developer. That often means I’m still working at 3am and drinking way too much Mountain Dew. I apologise for being rude.

Hello:

If I’m asking for too much then I’m happy to provide instruction on how to pull your head out of your own arse.

I was going to write a rude answer ... but as i'm out of the project now, i will simply say that if i was Jiri i will *never* do the installer for the DDEX provider, never, never, never ( it's a tool for developers, and if you think the instructions in the readme aren't clear enough you could try to explain what parts of it aren't clear, to update them, instead of being complaining ... ).

There are tons of people using the provider ( that has a *lot* of really nice features ) but only a *few* ( really *few* ) of them contributing to the project ( i don't know if there are more people that Jiri right now, that has done a really nice job since i left the project ... and before too ;) ), and there are a lot of areas where people can help, but ... looks like it's nice to get all for free without doing nothing, and complaint when somethings goes bad .... or didn't work as you expect .... and with the time really is discouraging ( at least for me it was at the time )

I had the same issue some time ago
here is how to recompile the 2.5.x solution with MONO and LINUX directive

Looks like Mono isn't supporting this charset. I know, that Mono has
no idea about ks_c_5601-1987, but this worked, at least in some
previous versions of Mono. Try to find some reference to shift_jis in
Mono changelog or sources, maybe previous version. Or just comment

Re: Generating entity classes using a firebird database

Mono Linux Unable to connect to FB Database.

2009-12-04T16:59:52Z

This is my first firebird / Mono project with .net so I'm a complete newbie.

I have a database stored int /var/db/menumate.fdb

I can connect to it fine using flamerobin.

I cant connect to it with the following code.

logger.Debug("Connecting to DB.");
            FbConnectionStringBuilder cs = new FbConnectionStringBuilder();
            cs.DataSource = "localhost";
            cs.Database = "/var/db/menumate.fdb";
            cs.UserID = "SYSDBA";
            cs.Password = "masterkey";
            cs.Dialect = 3;
            cs.Port = 3050;
            // I have tried these charsets just in case the make no difference.
            //cs.Charset = "NONE";
            //cs.Charset = "UNICODE_FSS";
            //cs.Charset = "ISO8859_1";

            string connectionString = cs.ToString();
            logger.Debug(connectionString);
            IDbConnection dbcon = new FbConnection(connectionString);
            logger.Debug("Opening Connection.");
            dbcon.Open(); // crashes here.
            logger.Debug("Connection Opened");
            IDbCommand dbcmd = dbcon.CreateCommand();
            string sql = "SELECT CONTACTS.CONTACTS_KEY,CONTACTS.NAME,CONTACTS.PIN FROM CONTACTS where CONTACT_TYPE = 0";
            logger.Debug("Assigning SQL");
            dbcmd.CommandText = sql;
            logger.Debug("ExecuteReader");
            IDataReader reader = dbcmd.ExecuteReader();
            logger.Debug("Reading");
            while(reader.Read()) {
                Staff StaffMember = new Staff();

                StaffMember.ID = reader.GetInt32(0);
                StaffMember.Name = reader.GetString(1);
                StaffMember.PIN = reader.GetString(2);
                StaffList.Add(StaffMember);
            }
            // clean up
            reader.Close();
            reader = null;
            dbcmd.Dispose();
            dbcmd = null;
            dbcon.Close();
            dbcon = null;

When try and connect to it in code I get the following error.
// My Nlog output see code.
MonoMethod.InternalInvoke => MainWindow.OnClick => XMLCache.buildStaff building Staff

// My Nlog output see code.
MainWindow.OnClick => XMLCache.buildStaff => DBMenuMate.HDServer.IData.getStaff Connecting to DB.

You have to use version 2.5+ of provider for DDEX connections.

Re: Generating entity classes using a firebird database

2009-12-04T13:28:29Z

My apologies I was misled a bit by the book Pro c# 2008, they used something called entity classes that I assumed was the same thing. But even when I try to add an entity model diagram I do not see Firebird as a valid data provider. This is even though, as I stated before, I can see the connection in the server explorer. I can make a dataset diagram though using the visual tools which would probably do just fine, but I still think I must have done something wrong somewhere.

Please forgive me for a being a bit newb as I am trying to learn what all the available methods are and what it takes to implement them before even deciding on which method I will employ into my program.

LINQ to SQL and Entity Framework are completely different pieces.

Generating entity classes using a firebird database

2009-12-04T10:57:48Z

What I am trying to do is use Linq to SQL and generate my entity classes like I would with a MS Sql database. I was under the impression that the latest versions supported the entity framework. I have already downloaded and set up the DDEX files and I can see my database in the server explorer but when I attempt to create the database diagram, which follows the autogeneration of my entity classes, it tells me "the selected object uses an unsupported data provider". Am I supposed to be able to use the designer to do this or am I just barking up the wrong tree?

Additional information:

I'm running Vistax64 and the project is using the embedded version of firebird (2.1.3) using c# with .net 3.5 sp1.

Thanks,

Robert

Re: Getting to Firebird after using another system

So you are wanting to use Firebird? Best thing if you need to transfer your customer addresses is to use a data integration software. I'd recommend looking at Datastage and Talend which would be two interesting programs to check to transfer the addresses. Keep us updated on the situation.

Reading BLOB SUB_TYPE TEXT is very very slow
---------------------------------------------

Key: DNET-286
URL: http://tracker.firebirdsql.org/browse/DNET-286
Project: .NET Data provider
Issue Type: Improvement
Components: ADO.NET Provider
Affects Versions: 2.5.1
Environment: VS2008 SP1, Windows Vista SP1, MS.Net 3.5, Firebird Server 2.1
Reporter: Tao Lin
Assignee: Jiri Cincura

I have a blob text file like define like this:

HtmlChuck BLOB SUB_TYPE TEXT SEGMENT SIZE 80 NOT NULL,

My connection string define like this:

string connectionString = "Data Source={0};Database={1};User=SYSDBA;password=masterkey;Dialect=1;Role=;Connection lifetime=15;Pooling=true;Packet Size=4096;";

I use the 'HtmlChunk' to store html page so that I can display it in runtime. The HtmlChuck value usually 8,000-10,000 bytes long. When I am using the latest Firebird.net provider to load the table by DataReader, it took 30 seconds to load 126 records. But if I change not connection to ODBC connection like this:

string connectionString = "DRIVER=Firebird/InterBase(r) driver; UID=SYSDBA; PWD=masterkey; DBNAME={0}:{1};

It took less than 1 second to load the same 126 records.

I think this is Firebird.net provider performance issue.

Re: VS to Firebird

2009-11-20T14:39:40Z

If I knew how to do it I’d gladly contribute and write the instructions.

I didn’t get the firebird Database for free. It was foisted upon me by a third party Software program the company uses.

I want to integrate the business processes. We have SQL, JADE and Firebird Databases that need to “talk” with each other . So I’ll need to access 2 Firebird Databases.

Read access is fine. I don’t own the data structure but I do own the data.

I’m not complaining because something has gone bad. I’m complaining because nothing has gone right.

Nothing personal guys. Firebird is a great product. I’m just frustrated I can’t work with it in VS yet.

Surely there is someone out there that can. And is willing to help me understand where I’m going wrong.

It may be that this is a VS problem not a firebird problem.

PS. I do a lot of work for charity. I contribute to user groups all over the world. I am not looking for a free ride , nor am I lazy. I am a developer. That often means I’m still working at 3am and drinking way too much Mountain Dew. I apologise for being rude.

If I’m asking for too much then I’m happy to provide instruction on how to pull your head out of your own arse.

I was going to write a rude answer ... but as i'm out of the project now, i will simply say that if i was Jiri i will *never* do the installer for the DDEX provider, never, never, never ( it's a tool for developers, and if you think the instructions in the readme aren't clear enough you could try to explain what parts of it aren't clear, to update them, instead of being complaining ... ).

There are tons of people using the provider ( that has a *lot* of really nice features ) but only a *few* ( really *few* ) of them contributing to the project ( i don't know if there are more people that Jiri right now, that has done a really nice job since i left the project ... and before too ;) ), and there are a lot of areas where people can help, but ... looks like it's nice to get all for free without doing nothing, and complaint when somethings goes bad .... or didn't work as you expect .... and with the time really is discouraging ( at least for me it was at the time )

Re: Transfering data to Firebird

2009-11-20T07:12:13Z

I would suggest extracting a csv file from your database. Once that is done, use Datastage or Talend Open Studio to operate the transfer. That is, to me, the best way to migrate data.

Re: VS to Firebird

2009-11-20T03:05:20Z

For what it's worth, I recently tried to get SQL Server 2005's
import/export wizard to find and use the Firebird .NET driver. I also
stumbled upon several problems, one of which was to even find
gacutil.exe, considering I didn't have VS installed on the machine in
question. I failed.

So, I also think that it would be very relevant to have an installer for
the .Net driver that would actually install the driver on the system in
a way that it's available to any application.

It is, unfortunately beyond my capabilities, within reasonable time, to
create such an installer, otherwise I would probably have already done
so. If ever I find time to educate myself in installer technologies and
how .Net drivers are supposed to be installed, I will hopefully also be
able to find time to create an installer for this driver. I just can't
see that happening. :-(

Kjell

VS to Firebird

2009-11-20T02:52:57Z

I have problems connecting to firebird from within Visual Studio.

I have some difficulty understanding the precise steps required in the provided ddex readme files.

I also have some problems being considered some sort of moron by the firebird group for suggesting the instructions are not as helpful as they could be.

So , in order that you understand I’m not some hairy arsed kid that fell out of a tree I’ll toot my own horn briefly

I am 43. When I was 16 I wrote my first stock control progam in BASIC

Since 2000 I have been coding in C# and VB and ASP

I have used VS2003 2005 2008 and I currently use VS2010 beta 2 as well as Coldfusion

I created an ERP/CRM system that traverses the LAN and WEB for a company with a turnover of over 20 Million a year and services their customers, suppliers and Remote users including smart phone an iPhone apps.

I am currently coding WPF and Silverlight apps for major companies and an international Charity organization.

I now want to integrate some of our LOB with third party firebird databases that exist on our servers.

2 years ago I tried without luck. Today I discover the same readme files.. the same confusion

How often do I use the gacutil?.. hardly ever.

How often do I need to run a registry hack to get a connection to work ?.. hardly ever

How often do I need to edit the machine.config file without fucking up my systems. Well Once is more than enough I reckon.

I want detailed, specifc, instructions on how to connect to a firebird database from within Visual Studio. Is that too much to ask?

If I’m asking for too much then I’m happy to provide instruction on how to pull your head out of your own arse.

Surely can. But if this is indendet for developers do we really need
to spent time and resources on this rather than on development? And
because our sources are open, everybody can contribute with this kind
of installer action. ;)
