I am trying to connect to a production database from a C# console project in .NET6 with VS 2022 using this piece of code
using SAPbobsCOM;
void InsertarActividad()
Company oCompany = new Company();
oCompany.Server = "IP_Server";
oCompany.CompanyDB = "DEMO";
oCompany.UserName = "manager";
oCompany.Password = "XXXXXX";
oCompany.DbUserName = "sa";
oCompany.DbPassword = "XXXXXX";
oCompany.DbServerType = BoDataServerTypes.dst_MSSQL2012;
oCompany.LicenseServer = "IPServer:30000";
int rdoConexion = oCompany.Connect();
oCompany.StartTransaction();
try
{
In rdoConnection variable I get a value of -10 and according to other code examples I think the value should be 0 because when I start the transaction it tells me that I am not connected
System.Runtime.InteropServices.COMException: ‘You are not connected to a company’
The values of oCompany are correct and in fact in an old VB.NET application that I am migrating they work and I don't know the reason why now in the same local network of the office in this project it does not connect me
Any ideas, please?
Thanks
It has been fixed by replacing the server IP with its name. I don't know why this is so but at least it connects me
Thanks

I have issue with my report. I install my app on two PCs. On first one I have SQL Server (MS SQL).
On first PC reports works. On second PC which is in same LAN report prompts me a window to set connection (which has empty, not editable database name box).
Report was created in Visual Studio 2017 with installed CRforVS 13.0.22
Client has installed CR runtime 13.0.22
I set connection programmatically using this code:
SqlConnectionStringBuilder csb = new SqlConnectionStringBuilder(connectionString);
DataSourceConnections dataSourceConnections = reportDocument.DataSourceConnections;
foreach (IConnectionInfo connectInfo in dataSourceConnections)
{
if (csb.IntegratedSecurity)
{
connectInfo.SetConnection(csb.DataSource, csb.InitialCatalog, true);
}
else
{
connectInfo.SetConnection(csb.DataSource, csb.InitialCatalog, false);
connectInfo.SetConnection(csb.DataSource, csb.InitialCatalog, csb.UserID, csb.Password);
reportDocument.SetDatabaseLogon(csb.UserID, csb.Password);
}
}
crystalReportViewer1.ReportSource = reportDocument;
crystalReportViewer1.Zoom(1);
I don't know what am I missing. Any help will be appreciated.
Adjust the host files of the affected computer. Include the SQL Server Name and its IP.
As part of a larger .Net 4.0 program I have a piece that queries the WMI for a list of network adapters and from that creates a list<> of physical adapters with MAC addresses.
It works on the machines I've tried it on, but when sent to the client, the list is empty. If they run IPCONFIG /ALL at a command prompt the MACs are listed.
My first thought is that there is a group policy in place preventing the enumeration, but everything I've found so far points to group policies that affects remote access through the firewall.
I've tried it locally as both a standard user and administration user, both provide the same list.
The empty query does not generate an exception.
I could ask them to go to the machines and check individual permissions, but since this seems to be a group issue that seems to be the wrong direction. What am I missing?
public static List<WmiNetworkInterfaceItem> QueryphysicalNetworkInterfaces()
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_NetworkAdapter");
List<WmiNetworkInterfaceItem> result = new List<WmiNetworkInterfaceItem>();
foreach (ManagementObject queryObj in searcher.Get()) {
if (queryObj["PhysicalAdapter"].Equals(true)) {
if (queryObj["AdapterTypeId"] != null) {
if (queryObj["AdapterTypeId"].ToString().Equals("0")) {
WmiNetworkInterfaceItem wmiNetworkInterfaceItem = new WmiNetworkInterfaceItem();
wmiNetworkInterfaceItem.Name = ManagementObjectPropertyString(queryObj["Name"]);
wmiNetworkInterfaceItem.MacAddress = ManagementObjectPropertyString(queryObj["MACAddress"]);
wmiNetworkInterfaceItem.PhysicalAdapter = queryObj["PhysicalAdapter"].Equals(true);
wmiNetworkInterfaceItem.AdapterType = ManagementObjectPropertyString(queryObj["AdapterType"]);
wmiNetworkInterfaceItem.AdapterTypeId = -1;
int.TryParse(ManagementObjectPropertyString(queryObj["AdapterTypeId"]), out wmiNetworkInterfaceItem.AdapterTypeId);
wmiNetworkInterfaceItem.Description = ManagementObjectPropertyString(queryObj["Description"]);
wmiNetworkInterfaceItem.PermanentAddress = ManagementObjectPropertyString(queryObj["PermanentAddress"]);
result.Add(wmiNetworkInterfaceItem);
}
}
}
}
return result;
}
Using the WBEMTest utility included with Windows as suggested by user atp_09 in comments, I was able to have the customer query his machine. Using this query exactly one adapter was returned in both standard and administrative user accounts indicating there was nothing in the machine preventing this from working.
SELECT * FROM Win32_NetworkAdapter where PhysicalAdapter = true
Upon further review there was an error in how I later dealt with the list with a single response.
Application: Connecting to BigQuery using BigQuery APIs for Java
Environment: Eclipse, Windows 7
My application was running fine until last night. I've made no changes (except for restarting my computer) and my code is suddenly giving me this error:
Application name is not set. Call Builder#setApplicationName.
Thankfully I had a tar'd version of my workspace from last night. I ran a folder compare and found the local_db.bin file was different. I deleted the existing local_db.bin file and tried to run the program again. And it worked fine!
Any idea why this might have happened?
Hopefully this will help anyone else who stumbles upon this issue.
Try this to set your application name
Drive service = new Drive.Builder(httpTransport, jsonFactory, null)
.setHttpRequestInitializer(credential)
.setApplicationName("Your app name")
.build();
If you are working with only Firebase Dynamic Links without Android or iOS app
Try this.
builder.setApplicationName(firebaseUtil.getApplicationName());
FirebaseUtil is custom class add keys and application name to this class
FirebaseDynamicLinks.Builder builder = new FirebaseDynamicLinks.Builder(
GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), null);
// initialize with api key
FirebaseDynamicLinksRequestInitializer firebaseDynamicLinksRequestInitializer = new FirebaseDynamicLinksRequestInitializer(
firebaseUtil.getFirebaseApiKey());
builder.setFirebaseDynamicLinksRequestInitializer(firebaseDynamicLinksRequestInitializer);
builder.setApplicationName(firebaseUtil.getApplicationName());
// build dynamic links
FirebaseDynamicLinks firebasedynamiclinks = builder.build();
// create Firebase Dynamic Links request
CreateShortDynamicLinkRequest createShortLinkRequest = new CreateShortDynamicLinkRequest();
createShortLinkRequest.setLongDynamicLink(firebaseUtil.getFirebaseUrlPrefix() + "?link=" + urlToShorten);
Suffix suffix = new Suffix();
suffix.setOption(firebaseUtil.getShortSuffixOption());
createShortLinkRequest.setSuffix(suffix);
// request short url
FirebaseDynamicLinks.ShortLinks.Create request = firebasedynamiclinks.shortLinks()
.create(createShortLinkRequest);
CreateShortDynamicLinkResponse createShortDynamicLinkResponse = request.execute();
I'm trying to synchronize an Sql Server database with SQL Azure Database (please be patient 'cause I don't fully understand Sync Framework). These are the requirements:
First: synchronize 1 table from Sql Azure to Sql Server
Second: synchronize 13 other tables (including the table I mentioned in the first step) from Sql Server to Azure.
I've created a console application, and this is the code:
1.I create one scope with the 13 tables:
DbSyncScopeDescription myScope = new DbSyncScopeDescription("alltablesyncgroup");
DbSyncTableDescription table = qlSyncDescriptionBuilder.GetDescriptionForTable("tablename", sqlServerConn);
myScope.Tables.Add(table); //repeated 13 times.
2.I Provision both data bases:
SqlSyncScopeProvisioning sqlAzureProv = new SqlSyncScopeProvisioning(sqlAzureConn,myScope);
if (!sqlAzureProv.ScopeExists("alltablesyncgroup"))
{
sqlAzureProv.Apply();
}
SqlSyncScopeProvisioning sqlServerProv = new SqlSyncScopeProvisioning(sqlServerConn, myScope);
if (!sqlServerProv.ScopeExists("alltablesyncgroup"))
{
sqlServerProv.Apply();
}
3.I create the SyncOrchestrator with the SyncDirectionOrder.Download to sync the firts table:
SqlConnection sqlServerConn = new SqlConnection(sqllocalConnectionString);
SqlConnection sqlAzureConn = new SqlConnection(sqlazureConnectionString);
SyncOrchestrator orch = new SyncOrchestrator
{
RemoteProvider = new SqlSyncProvider(scopeName, sqlAzureConn),
LocalProvider = new SqlSyncProvider(scopeName, sqlServerConn),
Direction = SyncDirectionOrder.Download
};
orch.Synchronize();
4.Later, I use the same function only changing the direction SyncDirectionOrder.Upload to sync the 13 remaining tables
SqlConnection sqlServerConn = new SqlConnection(sqllocalConnectionString);
SqlConnection sqlAzureConn = new SqlConnection(sqlazureConnectionString);
SyncOrchestrator orch = new SyncOrchestrator
{
RemoteProvider = new SqlSyncProvider(scopeName, sqlAzureConn),
LocalProvider = new SqlSyncProvider(scopeName, sqlServerConn),
Direction = SyncDirectionOrder.Upload
};
orch.Synchronize();
Now, here is the thing, obviously I'm doing it wrong 'cause when I download, the syncStats shows that a lot of change have been applied BUT I can't see it reflected on any data base and when I try to execute the Upload sync it seems to be going into a loop 'cause the Upload process doesn't stop.
Thanks!!!
first, you mentioned you only want to sync one table from Azure to your SQL Server but you're provisioning 13 tables in the scope. if you want one table, just provision a scope with one table. (e.g. one scope for the download with table, one scope for the upload with the rest of the tables)
to find out why rows are not synching, you can subscribe to the ApplyChangeFailed event for both sides, and check if there are conflicts or errors being encountered.
or you can enable Sync Framework tracing in verbose mode so you can see what's happening underneath.
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...
