Re: [Firebird-net-provider] [ Regarding connection speed with .Net
Hi, I had a similar problem before. In my case, it took more than 10 seconds to open a connection. It was a network setting problem but it took me so long to find out the remedy. The chance is, probably we do not share the same cause, so I do not get into the detail at first. Instead, let me ask you a question: Do you switch the network settings on the problematic client machine, say by using netsh commands, trying to use two separate networks? I did, and in my case, the cause of the slow connection was neglecting to delete dns settings on the tail-side network with which I tried to connect to FB.

Without batch query support, we can't do like,
strSQL = "select customerid from customers; select orderid, customerid from
orders";
FbDataAdapter da = new FbDataAdapter (strSQL, strConn); // strConn being
connection string
da.TableMappings.Add("Table", "Customers");
da.TableMappings.Add(Table1", "Orders");
da.Fill(ds);
can we?
Am I supposed to do something like this?
DataSet ds = new DataSet();
DataTable tbl;
tbl = ds.Tables.Add("Customers");
// add colums
tbl = ds.Tables.Add("Orders");
// add colums
strSQL1 = "select customerid from customers";
strSQL2 = "select orderid, customerid from orders";
FbDataAdapter da = new FbDataAdapter (strSQL1, strConn);
da.TableMappings.Add("Table", "Customers");
da.Fill(ds);
// create FbCommand cmd from a factory method
cmd.Connection = strConn;
cmd.CommandText = strSQL2;
da.SelectCommand = cmd; // re-assigning SelectCommand
da.TableMappings.Add(Table1", "Orders");

I know this part. To do this, I need to have two tables filled with date
within a single DataSet, boiling down to the above first question.

Re: [Firebird-net-provider] how to use relation
Hi Carlos, >Couldn't you use TableAdapters ( and fill them with data ) or fill the >dataset table using the TableAdapter ?? Yes, I use DataAdapter to fill a DataSet (I do not use TableAdapter as a policy to avoid design-time GUI dependancy). But because I have to create a DbCommand (FbCommand) using only a single SQL statement (since batch query is not supported), the Fill method of the DataAdapter populates only a single DataTable in the DataSet with data. On the other hand, as I understand, we need to add a Relation to the DataSet to obtain parent-child relation between two tables. So my question is, how can I populate the second table in the same DataSet? Or can I set tables from different DataSets into a Relation, and adding it to one of the DataSets' Relation will work to get parent-child relationship? Maybe I'm missing something very basic but please enlighten me. I want to establish parent-child relationship in the detached data objects level, not in the original database level.

Hi, I would like to set relation (parent-child) between multiple tables, but, unfortunately, I don't understand how to do it with FB provider.

Finally, you tell me how, and I thank you profundly. ascii_val sounds promising. I have been using my own UDF and didn't look into FB's standard UDF package. I'm porting socket-server apprecations from Win32/C++ to .NET. In those fields, you often have no choice but going down to bytes. You usually have no control over what is sent to your server. Sometimes you need to read binary protocol. Although this is not socket, a third party apprecation writes a byte into char(1) field in DB and I need to read it, willy-nilly. Thank you for your help.

I have a byte in the database (FB2.0). and we have a Byte type in .NET world. I would like to use the byte information in .NET as a byte. I'm not sure if there is a way to bring it without temporally converting it into unicode, so that's one of the reason I posted this question. I don't know what FW stands for. If it means .NET environment, surely not everything is unicode, although every character might be. If, unfortunately, converting it into a unicode char is unavoidable, then, I would like to know what is the simplest and standard way to do it. Anyway, I would like to know how to do byte-to-byte transfer :-).

> everything in FW work with unicode), then use simple conversion:

You can do
char c = 'a'
because 'a' is a Char.
You can't do
char c = (byte)'\xA0'; // a byte with the value of hexadecimal A0, not
letter 'a' in ASCII.
you need some decoding.
If I do,
byte b = (byte)'\xA0';
byte[] bytearray = { b };
char [] chararray = Encoding.UTF8.GetChars(bytearray);
int charCount = Encoding.UTF8.GetCharCount(bytearray);
then charCount = =0 // decoding fails
if I do
byte b = (byte)'\xA0';
byte zero = 0;
byte[] bytearray = { b, zero };
char [] chararray = Encoding.UTF8.GetChars(bytearray);
int charCount = Encoding.UTF8.GetCharCount(bytearray);
then charCount is 1. // decoding is successful.
if
byte b = (byte)'\x10'; // below 128, so ASCII range
byte[] bytearray = { b };
char [] chararray = Encoding.UTF8.GetChars(bytearray);
int charCount = Encoding.UTF8.GetCharCount(bytearray);
then charCount is 1. // decoding is successful.
Now, you see the problem.

I'm sorry but this is exactly where it started.
with the single-byte value being '\xA0'
byte.Parse(inputstring)
emits an error saying incorrect input format.
This would probably work only if the byte value is less than 128. But I need
full range of 0-255.

[Firebird-net-provider] how to read a single-byte from databasae
Hi,
I'm trying to read a single-byte in FB2.0 database as char(1) field with
charset/NONE. I am using the byte as binary information ranging 0-255, not
as a letter in text. With FbDataAdapter's Fill method, the data is
translated into a string in a DataTable. It seems that when the value of the
single-byte data exceeds 127, the byte turns into two-byte unicode char with
a default encoding. I do not want the original single byte to be translated
into unicode char. So I did something like:
DataTable dt = new DataTable();
dt.Columns.Add("dtd", typeof (byte)); // "dtd" is the name of the database
field
using(DbDataAdapter da = MyFbDataAdapterFactoryMethod(...))
{
da.Fill(dt);
}
then I got an error at Fill() method saying: incorrect input data format, it
should be 'Byte' type (translated into English).
What is a simple way to accomplish this kind of task? I'm new to .NET /.NET
data provider environment. It is a no-brainer with Win32/C++/IBX, but I
cannot figure it out with .NET.
Thanks,
Nobuya

Hi,
I'm afraid this is not the case, since, as I wrote in the post, I reagularly
get a quick response from the same IB 6.0 server (same network route) via
Win32/IBX but get a constant delay of 20 seconds via FB.net provider
2.0.1/.NET2.0. So I suspect that the provider is trying connections under
certain assumptions, something like "the database be FB2.0, no?, then FB1.0,
..., and finally, could it be IB6.0?." Maybe I'm a way off the mark. I
would like to know if the connection to IB6.0 should not be any different
from that to FB1.0, or, to know what I can do to specify that the connection
is to IB6.0 and circumvent failed connection try on the provider side.

Nobuya

[Firebird-net-provider] unsupported on-disk structure error again!
Hi all, About a week ago, I posted here for seeking a clue to solve my unsuccessful fb data provider installation. I got an error saying unsupported on-disk structure for file C:\; found 32779, support 10 when I tried to connect to FB2.0 database. I got several kind responses from the list but I could not find the exact cause. Then I uninstalled everything (data provider, ddex, VS 2005 SDK) and reinstalled with slight change in versions (provider 2.0.1.0; ddex 2.0.1.0 and less- configuration; FB2.0 classic server). Fortunately, this time, I was able to connect to FB2.0 database file form VS 2005. I was happy and since then I have been testing FB2.0/.Net from a test C# application with a help of tutorials. I was able to query with datareader, execute a storedprocedure, and use dataadapter. When I tried to use a storedprocedure with FbDataAdapter today, I found that I forgot to put my UDFs into FB2's UDF directory. So I recompiled my UDFs with new inlude files of FB2 and put regenerated my UDFs into FB2's UDF directory. I restarted FB2's service and tried again but it didn't work. Somehow, FB2 service failed ,showing 'Hang Application' in the event log. I thought "Ok, maybe I need some work to convert my UDFs compatible with FB2 but I have no time for this today" and I removed my UDFs from the UDF directory and reboot my PC. This time FB2 service started ok (I could connect to FB2 databases successfully with admin tool). But when I resume my test application / tutorials, I got the same error! unsupported on-disk structure for file C:\xxx ; found 32779, support 10 Now I can't execute the tutorials that I could do successfully before I put UDFs. With UDFs removed and rebooted, why can't I go back to the previous candition? And, more fundamentally, why does this 'unsupported ODS" stuff bothers me? I will appreciate any help!

Re: [Firebird-net-provider] un-supported disk structure
Oops, I sent a reply to wrong address Let me do it right. Hi, Scott, Thank you for the help. > To what disk File System type are you trying to restore this file to? Is > it an NTFS formatted disk, or FAT32? NTFS. > Have you tried restoring the data to a Firebird 1.0x or 1.5x database > instead of a version 2.x? ... As I described in the previous posts, now I believe that the issue is not so much a migration of data from IB6 to FB 2 as a proper data provider / FB setup, since, besides the the business database restored from IB6 backup, I cannot connect to test databases created de novo as FB2 (ODS v.11) with IBExpert either. At the same time I can look into, and manipulate with SQL queries, those business and test databases via IBExpert (admin tool) without a problem. Getting back to fundamentals, should I be able to connect to Firebird 2.0 database (ODS v.11) with Firebird .NET data provider 2.1.0.0 ?? Nobuya - Take Surveys. Earn Cash.

Re: [Firebird-net-provider] un-supported disk structure
Hi, > Check for correct DB file path. I have no other ideas what can it be... The path seems ok. Further tests on my side reveals that I can connect to old IB6.0 database (ODS ver 10) from VS 2005 via Firebird .NET data provider 2.1.0.0 but not to any FB 2.0 database (ODS ver11). Maybe I should uninstall everything and re-install everything ... but let me die hard. How can I make sure I am using correct versions of necessary dll/exe, either FB itself or data provider, or else, if I am to use ODS ver 11 FB database? Nobuya - Take Surveys. Earn Cash.

Re: [Firebird-net-provider] un-supported disk structure
Hi, > Maybe you should restore your database on 1.0, than on 1.5 and than on > 2.0.1... I created a test database with an admin tool, specifying type as Firebird 2.0. Then, I tried to connect to the database from VS 2005 and I got the exactly the same error. So, it has nothing to do with the database originated from old IB6.0. What am I doing wrong?

Re: [Firebird-net-provider] un-supported disk structure
Hi, Paul, thank you for the hint. > Just a hint, I think you need to verify gds32.dll version from system32 . > If you made all operations on that machine, could you have the old > gds32.dll > from previos IB6 instalation. I checked the gds32.dll in system32. It's property shows that its make is Firebird with the version of 6.3.1.12810. Judging from the file date, it was replaced recently. Correct me if I am wrong, but I doubt Firebird .Net data provider uses gds32.dll or fbclient.exe. I forgot to mention, in the origial post, the version of Firebird. It is 2.0.1.12810.

[Firebird-net-provider] un-supported disk structure
Hi, I am a newbie trying to migrate from IB6.0/IBX to FB2.x/.NET. FirebirdSql.Data.FirebirdClinet.dll version 2.1.0.0 FirebirdSql.VisualStudio.DataTools.dll 2.0.1.0 Windows XP, SP2, VS 2005 I installed VS SDK (not framework SDK). I downloaded firebird .net data provider and DDEX. I put entries into machine.config and set path in the DDEXProvider.reg and put it into the registry. Then, I opened a new project in VS 2005 and tried to add a new data source. In the Wizard, I could successfully select Firebird Data Provider from the pull-down. In the next window, I filled database path, user, etc. and hit Test connection button, and I go an error saying: unsupported on-disk structure for file c:\blah, blah : found 32779, support 10 Please help me with this. The target database file was restored from a IB6.0 backup (I used IB6.0 gbak for backup, and FB2.x gbak for restoration) . I can see the content of database with IBExpert. It says the target database' s properties are: Server version WI-V6.3.1.12810 Firebird 2.0 ODS version 11.0 Page Size 8192 Pages Allocated 730531 DB file size 5707MB client library c:\program files\firebird\firebird_2_0\bin\fbclient.dll client library version 2.0.1.12810 Thanks, Nobuya - Take Surveys.
