I'm trying to deploy my Application that uses a Firebird v2.5 database to a client machine.
I am trying to use a minimum installation, without the need to run any other installers. From what I gather, all I need to do is copy the "FBClient.dll" to the target application folder (which includes firebird database file). I have tried this and it still reports an error about not being able to find the correct .net data provider.
eg
C:\Program Files (x86)\MyApp\myApp.exe
C:\Program Files (x86)\MyApp\fbDatabase.fdb
C:\Program Files (x86)\MyApp\fbclient.dll
The error produced is:
Failed to find or load the registered .Net Framework Data Provider.
Also have copied, renamed and included fbclient.dll as fbembed.dll
I have also tried to copy a bunch of other files to the app directory, as well as placing fbclient.dll into the c:\, c:\windows, c:\windows\system.
I also tried installing the client installation, with no joy too.
Is there a way, that I can use the firebird database, without manually editing the machine.config files or using the gac and going through the hell that I went through to install firebird on the dev machine? I want an application that a user can install, not requiring that it be installed by a developer.
Please note, the application that I am writing is for a single machine, single user environment, who knows how to double click the install button, with the attention span of a gnat, that if required to do more than double click install and then press GO, will simply get bored and press the cancel, forget it button.
I add the file "FirebirdSql.Data.FirebirdClient.dll" to the application folder and I no longer get the Data provider error, instead I get the following
"Unable to complete network request to host \"DevMachine\"."
at FirebirdSql.Data.Client.Managed.Version10.GdsConnection.Connect()
at FirebirdSql.Data.FirebirdClient.ClientFactory.CreateManagedDatabase(FbConnectionString options)
at FirebirdSql.Data.FirebirdClient.ClientFactory.CreateDatabase(FbConnectionString options)
at FirebirdSql.Data.FirebirdClient.FbConnectionInternal.Connect()
I am trying to connect with the following
string file = #"C:\Program Files (x86)\MyApp\Test.FDB;";
FbConnection con = new FbConnection("User=SYSDBA;" + "Password=masterkey;" + "Database=" + file + "DataSource=Dev-VS-W7VM;" + "Port3050;" + "Dialect=3;" + "Charset=ISO8859_1;");
try
{
con.Open();
}
catch (Exception e)
{
MessageBox.Show(e.ToString());
}
I have included FirebirdSql.Data.FirebirdClient in my project and installation folder (..\MyApp)
Thank you in advance.
You have to grap a zip and copy FirebirdSql.Data.FirebirdClient.dll to bin folder.
I wonder how you wrote your application that it works without the file (probably installed .msi) :)
You needed to install .net provider
http://www.firebirdsql.org/en/net-provider/
The database file resides next to your application's exe module. So, you need in local server running or embedded server in order to work with data. For embedded server a minimal set of files is (specifed relatively to an application folder):
\UDF (folder with UDF needed if any)
\Intl (with contents from FB installation)
fbembed.dll
firebird.msg
ib_util.dll
icudt30.dll
icuin30.dll
icuuc30.dll
Microsoft.VC80.CRT.manifest
msvcp80.dll
msvcr80.dll
for a full scale server (i.e. not an embedded) a list of files would be:
\UDF (folder with UDF needed if any)
\Intl (with contents from FB installation)
fbserver.exe or fb_inet_server.exe
fbclient.dll
firebird.msg
ib_util.dll
icudt30.dll
icuin30.dll
icuuc30.dll
Microsoft.VC80.CRT.manifest
msvcp80.dll
msvcr80.dll
security2.fdb
firebird.conf (if non default parameters used)
But then you would need in setting up service record for FB
or start it as an application before your application start.
Installation of the Firebird as a service could be done with
instsvc.exe utility. Appropriate commands:
instsvc install -s -a
instsvc start
Also you should take care of two things:
FileName must be a local file, not in a shared folder from another server.
Appending the firebird server IP before the filename. If you are running your app always in the firebird server, or you are using embeded fbclient.dll, than it should be like
FbConnection con = new FbConnection("User=SYSDBA;" + "Password=masterkey;" + "Database=localhost:" + file + "DataSource=Dev-VS-W7VM;" + "Port3050;" + "Dialect=3;" + "Charset=ISO8859_1;");
Some fbclient.dll version will allow you not to add localhost and still connect on local files, or use \\servername\c:\filename format instead of localhost:c:\filename, but it is deprecated and not supposed to work anymore (and can work depending on windows version).

I develop client-server UWP app, and I want it to be deployed by sideloading (probably using WinAppDeployCmd or MDM) to the large set of devices by administrator.
But to launch, my application needs to know server IP address, which varies for each customer. I need to pass this setting somehow during deployment by administrator to every device.
Is there a way to set remote application settings? Or pass an XML config file along with appx? Or any other way to add some parameters during installation process?
Unlike e.g. MSI, there's no option to pass along "initial data" with a package for installation. One option is to install the package and then add your 'data' e.g.
Add-AppxPackage foo.appx
appdata = ApplicationDataManager.CreateForPackageFamily(foo_pkg_family)
appdata.LocalSettings.CreateContainer("x").values["y"] = z
Step 1 installs the package, most notably it will register the package for the user. That creates the package's appdata storage resources for the user. You can then use ApplicationDataManager (from a Win32/non-UWP process) to access appdata.
You may find AppData.exe handy. A simple exe using ApplicationDataManager to provide a cmdline interface to AppData. Given this or equivalent you could write a batch file
#ECHO Off
powershell -c Add-AppxPackage foo.appx
appdata.exe SET foopkgfamilyname local\configuration --value=x --type=string --data=y
I faced very strange behaviour - after I overwrite .NET exectables with new versions from network drive it cannot start.
When try to start from Windows Explorer it shows me following error:
[Window Title]
C:\Programs\zzz\clients.net\zzzNet.exe
[Content]
C:\Programs\zzz\clients.net\zzzNet.exe
The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.
I tried to execute following commands:
SxsTrace Trace -logfile:SxsTrace.etl
SxStrace Parse -logfile:SxSTrace.etl -outfile:SxSTrace.txt
And got following result:

It is quite simple .NET application (1 exe + 8 dll files). It was built for .NET 3.5 Client Profile.
I not defined any special "manifest" there. Just clicked "New Windows Forms Project" in Visual Studio and developed it.
Also app.config does not contain anything special - only primitive standard settings - appSettings and userSettings sections.
On PC where I developed it all is perfectly works. Problems only began when I copy these binaries to this particular VM and try to start.
Also please note - these executables were not installed in GAC or such, I just copied them into a folder on VM and started. And when it was 1st time all was working fine.
So, the problem pattern is following:
Copy .NET execuatbles to new VM (it is Win 7 x64), run it, all is working fine. Close it.
Build new version of .NET execuatbles on host PC, copy new .NET execuatbles to VM (with files overwriting).
Try to start - got mentioned problem.
After some shaman-style actions (like OS reboot, etc) it begin to work but why that happened at all?!
Why replacing .NET executables with new versions is causing SUCH HUGE PROBLEMS?!
Also the BIG QUESTION - is there any special procedure to replace .NET executables to keep them working? Because it is a new app development, I do not want lost so much time on every new executables installation. :-\
Could you please help? Because it looks completely weird!
Thank you in adance.
PS. I checked all VS projects - all they have PlatformTarget=AnyCPU. Also in run-time I can see ProcessType=MSIL (I show this info in AboutBox for application). So, there is no mix of x86/x64 binaries.
It seems that was related to mapped network drive behavior.
When I copied new files from network drive folder it copied wrong files - a strange random mess of new files and older ones (which were there before I updated them on VM host).
The scenario to make it working:
on VM: delete all files in a folder on network drive
on VM host: copy new files into a folder which is mapped as network drive on VM
on VM: copy files into target folder
on VM: run application - it works now
Weird thing. I remember I have seen something similar with Windows Explorer on Windows 2008 behaviour when copying updated win32 binaries.
I have setup my sqlite database path as
string AppPath = System.IO.Path.GetDirectoryName(Application.ExecutablePath);
dbName = AppPath + "\\data\\rbssystems.sqlite";
But when application is packed and installed using setup, my application uses
C:\Users\<username>\AppData\Local\VirtualStore\Program Files\RBS\data
it should be using
C:\Program Files\RBS\data
Can anyone tell whats going around and how to make it read database from
C:\Program Files\RBS\data
Thanks
Your app can't write to C:\Program Files unless it has administrative privileges. Windows automatically redirects you to C:\Users\<username>\AppData\Local\VirtualStore\Program Files instead. See this article for the explanation: http://blogs.windows.com/windows/archive/b/developers/archive/2009/08/04/user-account-control-data-redirection.aspx
Application data should always be in the AppData folder, never in Program Files.
I have a program in C# that use ODP.NET dlls:
oci.dll, ociw32.dll, Oracle.DataAccess.dll,
orannzsbb11.dll, oraocci11.dll, oraociicus11.dll,
OraOps11w.dll.
I've got 2 computers. First with whole ODAC package installed, and second without that package. But I have all required dlls in my exe directory, so ODAC is not a problem I think.
The difference between these computers is the path to the TNSNAMES file.
First: C:\app\OraHome_1\Network\admin\
Second: C:\Oracle\product\11.2.0\client_1\network\admin
On the first computer, the program works fine. But on the second one with the same connection string, I get the error:
cannot open connection (ORA-12154)
Using SQL Plus I can connect on both computers. How can I show my program the proper path to the tnsnames.ora file?
You can set the TNS_ADMIN environment variable programmatically. See this page for a step by step. That is if you wanted to change to a specific TNS_NAMES.ORA file. The Oracle Client must still be installed on the client machine.
From ConnectionStrings - without using TNS:
Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;
EDIT: Added 3rd option
Please see this question which could aid you in finding the current location of the client's TNS_NAMES.ORA file - which you could open and modify if you wish (add your own connection if it doesn't exist)
You don't need to care about the path of your TNSNames file: it'll be automatically discovered by the library itself... once you have it installed. That's the key point: distributing the dll within your project is not enough. You need to install ODP.Net on the machine that need to use it: actually the installation simply create a few registry entry, and one of them point to the right oracle dir (in which the library can find out the tnsnames when needed).
Morover, as someone pointed out, you don't need a tnsnams file at all. You could write everything needed inside the connection string.
Here's one I use in my environment:
Data Source= (DESCRIPTION =
(ENABLE = BROKEN)
(ADDRESS_LIST =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
(ADDRESS = (PROTOCOL = TCP)(Host =por10srv-a)(Port = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = por10.gruppo.autostrade.it)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 10)
(DELAY = 3)
)
)
);User ID=npa_collaudo;Password=npa_collaudo;
You don't need to install ODP.NET (or for that matter the Oracle Client) as you seem to have the required DLLs for a local distributable inline oracle client. In your case it's possible to have the TNSNAMES.ORA file located in the same folder as your executable and your specialised "inline oracle client" will pick it up from there. Otherwise the oracle client local to your application will try to pick it up from any client installed on the machine.
I was trying to use Firebird embedded server with Microsoft Visual C# 2010.
so here is what I done till now:
Downloaded Firebird .Net Data Provider (Firebird Client v2.5.2).
Downloaded Firebird Embedded server (Firebird Embedded Server v2.5.0).
Added a reference to FirebirdSql.Data.FirebirdClient.dll to my project.
Extracted and Copied fbembed.dll file to my application's directory.
Added my FDB file "TEST.FDB" to my application's directory.
Added "using FirebirdSql.Data.FirebirdClient;" statement.
So far so good (I suppose)...
Now when I try to connect to my FDB file using the following code:
FbConnection con = new FbConnection("User=SYSDBA;" + "Password=masterkey;" + "Database=TEST.FDB;" + "DataSource=127.0.0.1;" + "Port=3050;" + "Dialect=3;" + "Charset=UTF8;");
try {
con.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
I always get the messagebox which means the code is not connecting to my DB file properly.
am I doing something wrong? I'm really still noob with C# and I have no idea how to do this or fix it and I hope someone will help me with this.
thanks :)
EDIT: here is what I get in the exception:
FirebirdSql.Data.FirebirdClient.FbException

I finally I found the solution after 6 hours of work :)
most of answers on google are either wrong or so old.
all of them say that I only need to include fbembed.dll file to my project..
after some investigations I made. I found that I also need to add firebird.msg, firebird.conf, icudt30.dll, icuin30.dll, icuuc30.dll and ib_util.dll to my project files and to the output folder..
important notice: never use compact .Net data provider. because they made it for Normal and super firebird servers only. it won't work with embedded servers.
With Firebird 2.5 embedded, I copy all this files to the application directory :
aliases.conf (optional)
fbembed.dll
firebird.conf
firebird.msg
ib_util.dll
icudt30.dll
icuin30.dll
icuuc30.dll
Microsoft.VC80.CRT.manifest : -- Not sure if this 3 files are necessary
msvcp80.dll : -- but i copy them :)
msvcr80.dll : -- see http://www.firebirdnews.org/?p=2248
intl\fbintl.conf : Without those files you can't use
intl\fbintl.dll : all charset and collations
udf\* : if you want to use pre-build UDF
In the connection string, I specify that the server is embedded wih serverType=1:
User=SYSDBA;Password=masterkey;Database=E:\TEST.FDB;Dialect=3;Charset=UTF8;ServerType=1;
I forgot also IDPLicense.txt and IPLicense.txt, I think we have to also distribute them with the application for license issue ?
I put the Firebird DLLs in a dir in the project called Firebird. Added a Post Build event to copy the files.
copy $(ProjectDir)Firebird\*.dll $(ProjectDir)$(OutDir)*.dll"
These are the files and distribution you need for Firebird 3.0.5:
- root\plugins\engine12.dll
- root\intl\fbintl.conf
- root\intl\fbintl.dll
- root\fbclient.dll
- root\icudt52.dll
- root\icudt52l.dat
- root\icuuc52.dll
I check them out at the beginning of my application so I can inform what can go wrong.
