[Firebird-net-provider] Feedback from FBBackup/Restore
Hi Gang! Using Provider 2.6.0, I played around with FBBackup/FBRestore and it all works very good. Thanks for all the good work Jiri, Carlos and others!! I did not understand, though, how I can get some output or feedback from the backup/restore processes. On calling execute() the process starts and eventually ends, but I would like to have - at least - a notification when the method has finished it's job. I know how to do that when binding gbak.exe to a process object in .net 4, but I really would LOVE to do as much as possible using FBProvider. I do have links to weppages explaining fbbackup class, but the links are broken for at least a week now and I would like to advance on this. Can someone point me to the appropriate documentation? thanks! --- -- EditLive Enterprise is the world's most technically advanced content authoring tool.

Look at this list archives to find some related threads. OK, found some time to search the archives; found DNet 333, based upon which you changed the behaviour. I will have to think about an efficient way to change my code in different places. Problem so far only manifests in datagridview columns. But I am usually doing the formatting of datagridview columns in the designer for each separate datagridview, _NOT_ in some template or base class. May I ask why this suddenly has been changed? Are ADO.net whitebooks demanding to do so or was it a change to match requirements for certain software? Can I get an installer package for 2.5.2 provider somewhere? This would be my preferred solution so far, until I can come up with a solution for my datagridsviews. thanks! --- -- Achieve Improved Network Security with IP and DNS Reputation.

[Firebird-net-provider] Time is recognized as Timespan
Hello, now I successfully ported our project from .net 2.0 to .net 4.0. I am using provider 2.5.2. I have something strange, though. When I'm reading data from a firebird database (Server 1.5) and the field type is Time, I get an error when using a data adapter to fill a table with a datacolumn of datatype DateTime. The exception suggests that the value is interpreted as Timespan and can therefore not be written into a datacolumn of datatype DateTime. If I comment-out the definition of the datatype for the respective DataColumn, everything works, but the seconds are displayed in the corresponding DataGridView because if nothing is defined, the column will interpret the data as string and I can't use the time format hh:mm to suppress the seconds. If this is something known, can somebody please point me to relevant discussions, or if this is unknown, can you tell me what info you would need from me to analyse this?

[Firebird-net-provider] fbcommand.Parameters.Add /.AddRange (.net 4)
Hi Gang, I don't remember anyone posting this before, so I thought I'd
inform you. I am updating my application to use .net 4 with VS 2010.
Using the conversion wizard (opening a 3.5 or 2.0 project in VS2010),
the wizard is doing changes to code using FB provider, which then
leads to stack overflow exceptions.
Here is the problematic structure _BEFORE_ conversion (watch line
wrap!)...
FBCommand1.Parameters.Add(new FbParameter(@PM_IDREP, FbDbType.Char, 4,
System.Data.ParameterDirection.Input, false, ((byte)(0)), ((byte)(0)), ,
System.Data.DataRowVersion.Current, \1002\));
And here is the same line _AFTER_ conversion (again watch wrap!)...
FBCommand1.Parameters.AddRange(new FbParameter[] {new
FbParameter(@PM_IDREP, FbDbType.Char, 4,
System.Data.ParameterDirection.Input, false, ((byte)(0)), ((byte)(0)), ,
System.Data.DataRowVersion.Current, \1002\)});
which basically means that the converter is making a collection of
parameters out of each parameter. It does not do so in ALL places of
the project - so far I did not find out what makes these 2 places so
special... well... this is the oldest code snippet I do use which
involves fb provider functionality and I wouldn't do it like this
anyway today... strange enough though, isn't it?
Manually editing the line to the version BEFORE conversion will make
it run fine. But the converted version using AddRange(...) instead of
Add(...) will cause System.StackOverflowException.
I am still using fb provider 2.0.1.0
please excuse the signature following below...

Re: [Firebird-net-provider] FbDbType.Decimal param fails
For what it's worth, I am making excessive use of parameters with type Decimal, and I am experiencing _no_ problem at all. I am in the process of eliminating the last non-Firebird portions of databases our softare is based upon and only then will I be able to migrate from 1.5.x to the current 2.x branch. So, I am still using the 2.01 provider and FB 1.5 (all Dialect 3), if that's of any importance for determining why Decimal parameters are working fine for me. I am, though, declaring the parameters another way than you do. Specifically I do not declare precision and scale on the client side. All my Decimals do have at least a precision of 12 while yours obviously only has 8. According to Helen's Book, Decimals with precision 10 are stored differently. I am not in the position to guess if that can somehow be connected to your problem. But it's worth trying, so you could leave out the declaration of the precision and scale and also try with a target field of higher precision and scale. ciao, André -- ~~~Ihre Nachricht~~~ KG Hi Daniel, KG I'm not at my workstation today, so I can't cut and paste anything.

I don't know. If I remember correctly I have read that unicode takes an extra byte per character and I did not want to hit any technical limit (max. lenghth of index key and such...) And I dimly remember that there were such limits for FB 1.5, which have been extended along with 2.x. Our databases are still on FB 1.5 due to technical limitations of the old programming tools.

[Firebird-net-provider] arithmetic overflow mystery
Hello together, this is the first real problem I have with .net provider for more than 2 years; great work! Thanx! But this one is really scaring me. I get an FBException arithmetic exception, numeric overflow or string truncation, suddenly. And I only get it in .net using provider 2.0.1, the same query runs fine in IBExpert, for example, on the very same server and the same database. As far as I can tell, that routine is still running fine in the deployed version of my application... Here is what is causing the exception: Cmd_PosMax = new FbCommand(); Cmd_PosMax.Connection = Program.DBConn101; Cmd_PosMax.CommandText = Select + max(D3017003.P3017_017Z) + from + D3017003 + where + D3017003.P3017_001Z = @IDEBA ; Cmd_PosMax.Parameters.Add(@IDEBA, FbDbType.Char, 5); Cmd_PosMax.Parameters[@IDEBA].Value = IDEBA; sPoxMax = Cmd_PosMax.ExecuteScalar(); I don't have the slightest clue what is going on or wrong. And my experience is not good enough to know where to start looking. The parameter IDEBA at the time has a valid content (for example 27315, but the exception gets thrown on _all_ possible content, so it's not just the matter of one ID.

Re: [Firebird-net-provider] Asynchronous query execution available?
Matthias, please be kind with me if the following advice is boring for you, but you mentioned that you are migrating from Access. I am active in teaching developers how to migrate from dBase DBFs, which in general have a lot of similarities with Access MDBs. The biggest mistake I have to correct out of the minds of people is the problem of overindexing and the missing sense for housekeeping. But a query like the one you posted should - under normal circumstances - deliver records in FAR less than 5-10 seconds, even on a slow machine and with 10.000s of records in the tables. - Are you familiar with the concept of Backup/Restore in Firebird - Did you read Helen's book especially on the keep the Gap going (between OIT and the actual transaction) - Have you checked that you do not have too many indexes, maybe with a lot of duplicate entries. In comparison to MDBs/DBFs where a lot of indexing was sometimes necessary to make acceptable orders, Firebird is sometimes indeed performing better withOUT an index. - Did you probably put different indexes on the same field? Such could make the plan-optimizer in Firebird just go crazy. -- Mit freundlichen Grüssen, André Knappstein, EDV und Controlling Verwaltungs- und Erlebniszentrum Marina Rünthe beta Eigenheim GmbH Hafenweg 4 59192 Bergkamen-Rünthe Durchwahl: +49 2389 9240 140 ~~~Ihre Nachricht~~~ MW Hi, MW Madhu Sasidhar, MD schrieb: Mathias, Please check your query syntax and Db (indexes and keys).

Alex, I am also using OpenVPN to connect some remote clients including my home with the main building. I remember clearly that a local application could run easily using OpenVPN. I could dock the laptop into the LAN and did not have to change anything. So I would doubt that the problems are caused by OpenVPN. But at those times the application was written in Delphi and dBase. For 1 year already, we are using Remote Desktop/Terminal Server instead of locally installed applications. So I did not do any test using the .net-provider. I am sure I could make a test when I am at home, and report results to you tomorrow. I will be setting up something using the good old employee.fdb. If it works, I will send the project to you by e-mail. -- Mit freundlichen Grüssen, André Knappstein, EDV und Controlling Verwaltungs- und Erlebniszentrum Marina Rünthe beta Eigenheim GmbH Hafenweg 4 59192 Bergkamen-Rünthe Durchwahl: +49 2389 9240 140 ~~~Ihre Nachricht~~~ AC Hello André, AC My Fb server is 2.0.1 and I'm using the same client AC version in every computer on VPN.

Re: [Firebird-net-provider] FBException using VPN
Home early this evening, and tried at once. Well, seemed to have forgotten that the employee.fdb does not contain any date fields, only timestamps. But maybe this is already enough for testing? I set up a vqd (very quick and dirty) example connecting to the employee database on a server. To be quick I was using visual designer and so you will find the data components in the form1.designer.cs (*shiver*). I just sent the project 44KByte to your mail-adress. Open the project, select the fbconnection and change the servername, password and username to your needs. employee.fdb is aliased - like all databases - even on this testing server. If you don't have an alias for that you will also need to enter the server path. the test application runs fine through our openVPN tunnel.

Re: [Firebird-net-provider] Bug in FbConnection.GetSchema(Columns)
Jürgen, reading this I am quite glad that I have not needed this property in .net provider so far, because I admit it would exceed my comprehension of FB internals. Just in case I need it in future, I would like to get an additional clarification: Looking at a column which is not nullable because you set NOT NULL to the column, you would EXPECT the property is_nullable to be true, where true is represented by the numeric value 1. I would NOT, because literally the column is not nullable, and so I would not want to have this situation concluded as column is nullable. Instead I would either expect that the result is 0 where 0 means false or 1 where 1 means false (because the NOT-NULL flag in the system table is set to 1 as Helen described...) Looking at a column which is not nullable because you (only) set it's domain to a domain for which you set NOT NULL, not touching the NOT NULL constraint of the column itself, you would EXPECT the property is_nullable false. I also would, because the column is indeed not nullable. I am a bit worried, in any case, that you would expect different results for the 2 cases, because in both cases the column literally is not nullable. Maybe what you want and need is a (new?) property NOT_NULL_SET which could result to false for the column while is_nullable still _CAN_ return false because of the underlying domain. -- Mit freundlichen Grüssen, André Knappstein, EDV und Controlling Verwaltungs- und Erlebniszentrum Marina Rünthe beta Eigenheim GmbH Hafenweg 4 59192 Bergkamen-Rünthe Durchwahl: +49 2389 9240 140 - Check out the new SourceForge.net Marketplace.

Hello Jiri, Maybe what you want and need is a (new?) property NOT_NULL_SET which could result to false for the column while is_nullable still _CAN_ return false because of the underlying domain. JC Isn't this just negation of is_nullable? BTW in schema table are some JC well-known columns so you cannot adding/removing some in a free way. No, not necessarily. You can set the column's NOT NULL in addition to it's Domain's NOT NULL. That would be double for now. Once you remove the NOT NULL from the domain, this column would still remain not nullable.

Now when ever more than 11 users log in simultaneously on FB the server crashes. The log file generated tell that cannot handle this many uses at a time.

Re: [Firebird-net-provider] DDEX provider - support files and installation
2.1. BTW no matter wheter you have VS SDK you can use ...Less.reg, isn't it? 3. What about installation. Maybe should provide some no so common path like %ProgramFiles%\FirebirdClient, 'cause there're *.txt files with same name from FirebirdClient installation, so during install some can be confused. I know, it's not a big deal, bug it's also small change. Jiri, all of that sounds VERY good to me. If the time for implementing these changes can be spared this will be a big help for a lot of people. About developers and their abilities: the world is not just black and white but has a lot of shades between. I would not call myself a real developer and especially I do not have time to learn about all new things at once. But I wrote quite a big application, now half based on Firebird and already 5% written in C#. And the income of about 50 employees depends on that. So I am also a bit more than a hobbyist. I always demonstrate in my workshops how to use ODBC in the beginning, and once the attendees understood ADO.net principles, they do not need DDEX anyway. But those who do not listen to me are already re-converting their just converted-to-Firebird applications over to MSSQL just because it's too complicated to install the designtime support for the FB provider.

Re: [Firebird-net-provider] unexpected problem with Euro sign

[Firebird-net-provider] unexpected problem with Euro sign
Hello Gang, I am a bit puzzled about a problem which came quite unexpected to me. It seems that I cannot get our Euro-sign (ALT+0128) through to the client GUI via the .net Provider. Database standard for character type fields is ISO8859_1, Database-fields are ISO8859_1, Charset of Connection is ISO8859_1 All is well when querying the database with Delphi-components, or via ODBC to old dBase applications, or via ODBC to C#-programs. Isn't ISO8859_1 the correct charset for also transmitting Euro-signs? And if it is not, why does it nevertheless work with other components? Anf if it is not, which _IS_ a good charset for this?

Re: [Firebird-net-provider] unexpected problem with Euro sign
Damn, I missed, that you're not inserting (but the connection string should be changed at all). What exception you get? No problem, because for the nearest future I definitely do plan to insert data via the (new) .net application. I am doing the latest tests and now stumbled over that curiosity. I do NOT get any exception. Just the character which is shown as Euro symbol in other applications is shown as a placeholder symbol when using the .net Provider. Other applications also includes IBExpert which - as I understand - is written in Delphi. Other applications also includes my own old dBase and Delphi applications, either with native drivers or via BDE/ODBC. Also everything works fine when I am using the Microsoft net provider for ODBC. I tried changing the charset of the connection to UNICODE_FSS but to no avail. Instead of showing rectangle placeholder now I just get an empty space. When I ENTER data with .net provider and charset UNICODE_FSS the result will be stored in the database as question mark (?); querying the database again will also deliver a question mark.

Thanks for the answer, Carlos. So, I should use Win1252 and be well? That's not too big a problem. I have about 300 tables, but most of the objects do not override the database's charset. Can I change the database's charset by restoring a backed up db into an (empty) database with another charset? One questions remains, though.

I will try Win1252 because I don't want the 2 bytes extra for Unicode. Thanks, André CGÁ Whatever you are trying to achieve here, note that there is no euro- CGÁ character in ISO-8859-1.

Re: [Firebird-net-provider] Enhacement for FBCommand
Paul,
I still did not find a way to reply to this mail-list thingy from
behind our proxy, so I hope this message will get through to you.
The function you wish for does not belong into a command-feature or
new method, but you can easily implement it yourself.
To do that, connect with sufficient privileges and query the system
tables via that connection.
select
SP.RDB$Procedure_ID
from
RDB$Procedures SP
where
SP.RDB$Procedure_Name = :PM_TheProcedureName
You can hand the procedure name in question to that query and if you
receive a result, then a procedure with the same name exists in the
database.
I would be aware of the danger that the procedure could probably have
the same name, but maybe it has a different content/effect from the
one you wish to implement/recreate.
In addition I think I remember that only with classic server engine a
listed stored proc is active already for the next connection to the
database.
Hi
I face with this situation:
Some customers want to have reports or export 'patterns' from fb database.
For that I have some possibilities as sql query or stored procedures. For
query I make all by code. For stored procedures I have 2 situation, first,
SP exist in database, second SP not exist. If SP exist , just run, etc. For
this case it would be useful to have a method to check if SP exist in
database, if not, recreate procedure. (this works only for FB2 I think, for
FB 1.x just create).
Sample code:
FBCommand fbCommand1 = new FBCommand();
fbCommand1.CommandType = CommandType.StoredProcedure;
if (!fbCommand1.Exists) {fbCommand.Recreate()};
What do you think about ???
TIA,
Paul

Re: [Firebird-net-provider] Parameterized Query
Hello Peter, I'm afraid I can't, because I'm an awfully bad teacher. I can try just this: without that association the adapter does not know of your defined parameter. The need to supply the selectcommand-object to the adapter, I think, is basic knowledge for dealing with ADO.net objects. While I still have some problems with basics in C#/ADO.net myself, this one I think is quite clear. Check the OLH maybe on Fill method. There you will find: The Fill method retrieves rows from the data source using the SELECT statement specified by an associated SelectCommand property. -- Mit freundlichen Grüssen, André Knappstein, EDV und Controlling Verwaltungs- und Erlebniszentrum Marina Rünthe beta Eigenheim GmbH Hafenweg 4 59192 Bergkamen-Rünthe Durchwahl: +49 2389 9240 140 ~~~Ihre Nachricht~~~ PD Thank you André PD Works perfectly! PD I don't really understand your explanation. PD I suppose I really don't understand why it is possible to retrieve data from PD the database when the query has no parameters without the addition of your PD below suggestion. PD And why I need the extra line when the query uses parameters. PD If possible could you give me some more information to improve my PD understanding of this? PD Thanks for your time, PD Peter.

PD Don't know if that is the culprit in your case, but does it get PD better, if you add the above command line?? PD ciao, PD André Hi, I am trying to use a parameter in one of my queries but consistently get PD the following error: 'Prepare adapter to retrieve information from db. Dim daDuePacks As New FbDataAdapter(sDuePackSelect, conn) 'Add table to the Module based dataset. daDuePacks.Fill(m_dsDocoInfo, DuePacks) Can someone please tell me what I'm doing wrong?
