Hello:
my answers are written within the original text..
Thanks. :)
When I change FbDataAdapter - e.g. I change select query - I can only
generate NEW Dataset. There is no way of updating my existing Dataset.. This
behaviour is unpleasant because in the time of updating DataAdapter I
usually have some other properties of Dataset already set.. Generating of
new Dataset means that I'am losing these changes made on the Dataset and I
have to make them manually again. In fact it means that I do not use the
"auto generate dataset" feature in this case...
I have no idea how difficult is developing the design-time ability of
DataAdapter to keep "its Dataset" up-to-date but I am sure that many people
would appreciate such behaviour..
The best will be to use the DDEX provider to get the Visual Studio
Integration of the provider.
First - property FbDataReader.HasRows returns always true. Oops - I have
searched it up in the documentation just now and it says that this property
simply is always true.. Ehm - why should we have such property then?
According to my knowledge, there is no way how to determine whether executed
query has returned some rows and (if yes) how many rows it has returned..
..Am i wrong?
No, and this is as designed.
Second - we are using firebird databases with Unicode charset - i.e.
rdb$bytes_per_character is set to value 3.
We have following problem with the provider - sometimes it raises an
IscException(335544321), even though there is (in my opinion) no need for
throwing any exception. The same SQL statement that raises this exception
via FbProvider is succesfully executed via IB Expert.
IBExpert doesn't have proper UTF-8 support so it's not a valid test ;)
I wanted to make a test case for you, but did not have time, sorry..
Please do it when you have the time and send it to me.
Well - I'm the one who had problem with this too and spammed this conference
a lot about solving it ;-) the result is that I'm able to use FbConnection,
Command etc. in the design-time - I can set properties and let VS to manage
creating of these components etc. But full integration does not work at my
PC :-( - in VS dialogues there is no FbProvider in the list and if yes,
choosing FbProvider leads to errors.. But I am not sure if the your
intension was to achieve full integration of FbProvider into VS --> maybe I
simply do not know what is a bug and what is "unsupported feature"..
Some questions here:
1. The Computer where you are trying to install the DDEX provider where
having Visual Studio 2005 betas ??
2 . Have you installed the Visual Studio SDK ( it's not th e:NET
Framework SDK ), more info about it here:

3 . Have you modifed the machine.config file of .NET 2.0 according to
the changes proposed in the ReadmeDDEX.txt
4. Have you combined the .reg file that comes with the provider into the
Windows Registry with the %path% modified according to the changes
proposed in ReadmeDDEX.txt ??
