Setting up a Linked Server login for EasySoft Salesforce ODBC Driver

We're currently using EasySoft's excellent Salesforce ODBC Driver to be able to treat our Salesforce org as if it were another SQL database (really useful for updating legacy stored procedures by rewriting queries that reference migrated Dynamics tables to query Salesforce instead!) We were working on updating a particular page in our website that needed to use it but was running into permissions issues when querying it, the error was:

Access to the remote server is denied because no login-mapping exists

For future reference, this means that the account the website was connecting with wasn't granted permission to connect to the ODBC driver since it's set up as a "Linked Server", and SQL server doesn't just let you query those unless you've got sysadmin privileges, or unless the account is specifically set up to connect to them. Here's the code I used to resolve the issue:

--removing previous login, because I had to tweak this a few times
exec sp_droplinkedsrvlogin @rmtsrvname= 'easysoft connection name' , 
     @locallogin= 'db login name'

exec sp_addlinkedsrvlogin @rmtsrvname = 'easysoft connection name',
     @locallogin =  'db login name',
     @useself = false,   --defaults to true and ignores the below
     @rmtuser = 'salesforce username', --already specified in easysoft config, still have to specify it here for some reason
     @rmtpassword = 'salesforce pw'

Using Log4Net to use both event log and a rolling log file

Here's the config section, note that the applicationNameproperty in the EventLogAppender needs to be the same as the event source in the windows event log that you want to log to.  If the event source doesn't exist, that appender won't work.  In this particular project I create that during install using WiX (which is covered in another post)

    <appendername="RollingLogFileAppender"type="log4net.Appender.RollingFileAppender">      <filevalue="log.txt" />      <datePatternvalue="dd-MM-yyyy" />      <appendToFilevalue="true" />      <locationinfovalue="false" />      <rollingStylevalue="Size" />      <maximumFileSizevalue="1MB" />      <maxSizeRollBackupsvalue="10" />      <staticLogFileNamevalue="true" />      <layouttype="log4net.Layout.PatternLayout">        <conv…

Using WiX to create an event source during install of a .NET framework project

Edit: so I guess I wasn't the only one confused with this stuff, as it's been my most popular post by far!  If I've helped you out or saved you some time, please let me know in the comments :)

In order for this to work, you have to add references to WixUtilExtension and WixNetFxExtension to your WiX project.  Once that's done, add this inside a <Component> element:

<Util:EventSourcexmlns:Util=""Name="EVENTSOURCEGOESHERE"Log="Application"EventMessageFile="[NETFRAMEWORK40FULLINSTALLROOTDIR]EventLogMessages.dll" />
Obviously replace EVENTSOURCEGOESHERE with your event source name.  NETFRAMEWORK40FULLINSTALLROOTDIR is a property set by the WixNetFxExtension which stores the path to the .NET framework v4 directory, but you can replace this with the corresponding property for the directory containing the relevant EventLogMessages.dll file.  So if you're using the .NET framewo…

Umbraco Deployment Checklist

This is primarily aimed at deploying from Visual Studio to an Azure Web App + Azure SQL database, feel free to skip bits that aren't relevant if you're doing other things.

Prerequisites for developing locally:
Visual Studio (obviously)
Ensure IIS URL Rewrite module is installed using web platform installer (other downloads from MS documentation don't seem to work)

Set up Azure:
Make a new SQL Database in Azure, take note of the server name, database name, admin login and admin password.  If you already have a server and resource group, automate with Powershell as shown below (you'll need to replace the param values):
New-AzureRmSqlDatabase -DatabaseName "UmbracoDatabase" -ServerName "TheServer" -ResourceGroupName "Whatever" -Edition "Basic"
Add your IP to the Azure SQL db firewall so Umbraco can connect to it later when running locally
Create a new Azure web app, either manually or via Powershell:
New-AzureRmWebApp -ResourceGroupName…
