I am trying to interact with a Notes database (my personal mail file), via C# and am stuck right out of the gate, trying to open the database with the following code:
string sNotesSourceFolder = "$Inbox";
string sUserName = "scady";
string sMailFile = #"NotesMail_FDrive\ARchives\" + sUserName + ".nsf";
string sServerName = #"Answers1/Answers";
string sPassword = "xxxxxx";
//Creating the notes session
NotesSession session = new NotesSession();
session.Initialize(sPassword);
NotesDatabase NotesDb = session.GetDatabase(sServerName, sMailFile, false);
//If the database is not already open then open it.
if (!NotesDb.IsOpen)
{
NotesDb.Open();
}
calling session.GetDatabase() with the server name and path the the nsf file returns null which, apparently means it could not open the db.
I am running this code locally, against a Notes server called "Answers1/Answers". I am now thinking based on From the Notes server, the nsf files are located on a network fileshare of "NotesMail_FDrive\ARchives\xyz.nsf".
Is the server on which the file resides a Notes server or just a network share?
If it's a network share, you need the drive mapping, but sServerName would be "" to get to a "local" drive. I'm assuming Notesdata1 is a directory on X, so if it's the drive name, remove it.
string sMailFile = #"X:\Notesdata1\NotesMail\ARchives\scady.nsf";
string sServerName = #"";
If it's a Notes server AND Notesdata1 is the data directory for the Notes server, then
string sMailFile = #"NotesMail\ARchives\scady.nsf";
string sServerName = #"Answers1/Answers";
Sorry I didn't notice this on the first pass...
The value for sMailFile should not be "\10.10.10.71\notesdata1\NotesMail\ARchives\scady.nsf". The other two values that you have commented out are also wrong. The arguments for getDatabase are the Domino server's distinguished name, and a relative path. No server IP, no volume, and no "file:" prefix. Just something like this: "archives\scady.nsf". It should be exactly what you see for the path when you open up the database in your Notes client and bring up the database properties dialog.
Previous Answer
Your sServername variable contains the Domino server's distinguished name, as it should.
But why are you using File.Exists? The Domino server wants exclusive access to all of the files in its data tree. If you are actually successfully accessing the file on the Domino server via a filesystem call, then perhaps you are locking the Domino server out of accessing it.
But also: where are you running this code? Are you running it on the same computer, and under the same account that you normally use to read your email? Or on a different computer and account?

I created my vb.net project to .exe file.
During installation on another machine, one can change the location of installing package to any drive.
In my project, I have set my app.config to point the Database that is available in c:\project.
If I suppose, while installation, when I change the location of installation to **d:** or anywhere, I get invalid access db.
What I want is:
I want to reconfigure my app.config file automatically, by detecting its current db location.
Imports System.Configuration
Imports System.Configuration.ConfigurationManager
Dim config As System.Configuration.Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
config.ConnectionStrings.ConnectionStrings("MyProject.Properties.Settings.MyProjectConString").ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;DataSource=|DataDirectory|\SampleDB;Persist Security Info=True;"
config.Save(ConfigurationSaveMode.Modified)
Where MyProject.Properties.Settings.MyProjectConString is the name of your project and connection string.
Although this is too late to answer as the question is very old but I think this might help someone else in the future.
So, there is a way to change the Connection String value in the runtime. Since connection string is a read-only item like all other items that are on Application Scope under My.Settings so we can't change it using My.Setting.ConnectionString = "Something". But here is the code by which you can solve the issue and change any My.Settings item that is on Application Scope in the runtime.
So the code is,
My.Settings.Item("ConnectionString") = "Something"
simple...
MsgBox(My.Settings.Item("remoteAddress").ToString)
My.Settings.Item("remoteAddress") = "abcserver.servebbs.net"
My.Settings.Save()
MsgBox(My.Settings.Item("remoteAddress").ToString)
You have three options:
1.) Create and use a folder in C:\Databse and set your connection string at design time.
2.)Add the database to the project's data source at design time, then use '|Data Directory|\mydb.mdb' as your connection string.
3.) And if you use sqlserver, you don't need to worry about the location of the database once you have attached the database to sqlserver. You only need to use the proper connection string eg 'Data Source=.; Database = mydb; Integrated Security = False; Username=myusername; Password = mypassword; User Instance = false'.
The above is an example of a sql server with SQL Authentication mode as login, if you use Windows Authentication, set Integrated Security = True and remove both username and password.
This is my first post to this precious website. I am a new learner of vb.net. I am working on a simple purchase project, where i got some errors. But the first thing is which baffled me is:
This is my connection string at module level, on the developed machine.
Public strCn As String = "Data Source = (local); Initial Catalog = PSys; Integrated Security = false; User ID = sa; Password = 123;"
Is it mandatory that Data Source must be the original name of the System Name. I mean If i use (local) or using ( . ), so will it work or not? Because when i copy my project to any other system for further development so every time i need to change the Data source, otherwise i get the error that: "Network-related or instance-specific error occurred......."
Kindly guide me that what i need to do.
When you are developing an application which uses a database server such as MsSQL it is not wise to install the server along with your application in every pc which is installed to. For example what are you going to do if a customer has a local network with 10 computers? Are you going to install SQL server in all 10 of them? And if so what if they need to share data?
So your best approach (based on common practice by other applications) will be to allow the user to install the SQL server where he wants and let him configure your application and point it to the server's location. If you follow that path then the configuration of your application can be in the setup application or in the application itself.
Now about the development phase, I had a similar situation in which I needed to develop the same application in two different computers. What I did was to install the SQL server in both of them with a named instance "sqlexpress" then in the application I used the
Data.SqlClient.SqlConnectionStringBuilder
class to build the connection string. I did something like this:
Public Function getDevConnectionString() As String
Dim csb As New Data.SqlClient.SqlConnectionStringBuilder(My.Settings.dbConnectionString) '<-My original cs in app settings
csb.DataSource = My.Computer.Name & "\sqlexpress"
Return csb.ConnectionString
End Function
Whenever I need a connection string I simply call getDevConnectionString() which returns the connection string based on the computer name plus the sql server instance name. For example:
Dim cs As String
#If DEBUG Then
cs = getDevConnectionString()
#Else
cs = getReleaseConnectionString()
#End If
where getReleaseConnectionString() is the function that returns your connection string configured by the customer.
Hope this point you the right direction...
i want to view the test.db file, i search for it's editor but didn't get any one
So please help to see the it in editor as like sql server.
i found some sqlite editor but it's not an sqlite file on most forum it say that it is an paradox .db file.
So how do i open it
Thanks
To access Paradox tables in .NET you can use ODBC. Here's a small example (in C#):
private static void RunMinimumParadoxTest()
{
const string ConnectionStringFormat =
"Driver={{Microsoft Paradox Driver (*.db )}};Uid={0};UserCommitSync=Yes;Threads=3;SafeTransactions=0;" +
"ParadoxUserName={0};ParadoxNetStyle=4.x;ParadoxNetPath={1};PageTimeout=5;MaxScanRows=8;" +
"MaxBufferSize=65535;DriverID=538;Fil=Paradox 7.X;DefaultDir={2};Dbq={2};CollatingSequence={3}";
DbProviderFactory factory = DbProviderFactories.GetFactory("System.Data.Odbc");
using (DbConnection connection = factory.CreateConnection())
{
string userName = "Tor";
string paradoxNetPath = #"C:\BdeNet";
string databasePath = #"C:\LangloMainSrv\LData\Ordre\LordWin\Database2011";
string collatingSequence = "Norwegian-Danish";
connection.ConnectionString =
String.Format(ConnectionStringFormat, userName, paradoxNetPath, databasePath, collatingSequence);
connection.Open();
using (DbCommand command = connection.CreateCommand())
{
command.CommandText = "select Count(*) from [OrdreDet] where [Ordrenr] = 81699002";
object itemCount = command.ExecuteScalar();
Console.WriteLine("Order items: {0}", itemCount);
Console.ReadKey();
}
}
}

A Paradox db file contains just one flat table. The actual structure of the DB file changed over time and different versions. But you can usually open the DB file with MS Excel - of course that changed over different versions too.
As noted above, other database applications, also including Paradox for Dos and Paradox for Windows, will open the file and other features as well. The key, for example is in the PX file with the same table name.
All of this assumes the table is not password protected, which an application database could be - or that you know the password. Beware if you get an error to that effect.
You can open and view Paradox database files using Database Desktop that is shipped with Borland C++Builder. A free alternative is BB's Database Desktop. The software may require administrator privileges to run correctly.
You can use gnumeric spreadsheet, paradox-db-reader or BB database desktop to read db paradox file.
BB database dekstop able to read XG0 file too.
BB's Database Desktop now called JEDI Database Desktop, but project is closed and it couldn't edit my table. I have had to use some hack: open *.db file in MS Excel 2007, edit it, export to *.csv, close file then Open *.db file in Paradox Data Editor 3.2.0, clear all table data and import previosly saved csv-file. And it works (don't know why but this app can't insert row in my file itself)!
I'm building an application based on the WebSharingAppDemo-CEProviderEndToEnd. When I deploy the server portion on a server, the code gives the error "The path is not valid. Check the directory for the database." during the call to NeedsScope() in the CeWebSyncService.cs file.
Obviously the server can't access the client's sdf but what is supposed to happen to make this work? The app uses batching to send the data and the batches have to be marshalled across to the temp directory but this problem is occurring before any files have been batched over. There is nothing for the server to look at to determine whether the peerProivider needs scope. What am I missing?
public bool NeedsScope()
{
Log("NeedsSchema: {0}", this.peerProvider.Connection.ConnectionString);
SqlCeSyncScopeProvisioning prov = new SqlCeSyncScopeProvisioning();
return !prov.ScopeExists(this.peerProvider.ScopeName, (SqlCeConnection)this.peerProvider.Connection);
}
I noticed that the sample was making use of a proxy to speak w/ the CE file but a provider (not a proxy) to speak w/ the sql server.
I switched it so there is a proxy to reach the SQL server and a provider to access the CE file.
That seems to work for me.
stats = synchronizationHelper.SynchronizeProviders(srcProvider, destinationProxy);
vs.
SyncOperationStatistics stats = syncHelper.SynchronizeProviders(srcProxy, destinationProvider);
I am writing a launcher program, and when I go to start the process I get the "The directory name is invalid" error. Here is the code that is launching the process:
Const DEBUG_ROOT = _
"Z:\Kiosk_JC\KioskSignIn.root\KioskSignIn\KioskSignIn\KioskSignIn\bin\Debug"
Dim oKiosk As New System.Diagnostics.Process
oKiosk.StartInfo.UserName = oEnc.Decrypt(Username)
oKiosk.StartInfo.Password = oEnc.DecryptSecure(Password)
oKiosk.StartInfo.Domain = oEnc.Decrypt(Domain)
''// The AddBS function appends a '\' to the passed string if it is not present
oKiosk.StartInfo.WorkingDirectory = AddBS(DEBUG_ROOT)
oKiosk.StartInfo.FileName = "KioskSignIn.exe"
oKiosk.StartInfo.UseShellExecute = False
Dim proc As Process = Nothing
proc = System.Diagnostics.Process.Start(oKiosk.StartInfo)
I saw on another question here that I needed to set the WorkingDirectory (before I started searching I was getting the error). Even though I have this property set, I am still getting the error. Any thoughts?
More info
I should also note that my Z:\ is a on my network. I have a function that resolves a path to UNC. When I ran this function on DEBUG_ROOT, I get the same error.
I tried moving the application to c:\kiosk. Same result. I am logged in as the user I am impersonating, so I have access to all shares and files.

Referred Post
Mapped drives are per-user. You are likely starting the process with a different user.
Sounds like the process can't see the Z: drive or doesn't have security access. What user context does the app run under? Perhaps the Z: drive is not available in that context.
I got the same error as you do. most likely the user you use to run the process does not have access to specified resource (exe file)
try to move your exe to some other location and/or give your user access rights to the file.
