I'm using WiX 3.8 to create a Boot Strapper and have added a new EditBox to
the Options page, to allow the user to enter a database instance name and I
use this to install SQL Express 2014 and create an instance for the user.
This works fine !
In bundle.wxs :
<Variable Name="txtDBInstance" Type="string" Value=""
bal:Overridable="yes" />
In my Theme xml file, for the "Options" page :
<Editbox Name="txtDBInstance" X="114" Y="-43" Width="150" Height="21"
TabStop="yes" FontId="3">[txtDBInstance]</Editbox>
Then in the ExePackage part of my SQL Server fragment (cut-down for brevity)
:
<ExePackage Compressed="no"
DetectCondition="SqlInstanceFound_x64"
DisplayName="Installing SQL Server Express 2014"
Id="SQLServerExpressInstall_x64"
InstallCommand='/Q /ACTION=Install
/INSTANCENAME=[txtDBInstance] />
But I also want to check the registry to see if an instance already exists
with that name and if so update that instance. I have a series of
Util:RegistrySeach elements, that work ok if I hard-code the name of the
instance to check for e.g. if one was called "MY_DBINSTANCE" :
<util:RegistrySearch Id="SqlInstanceKeyFound_x64"
Root="HKLM"
Key="SOFTWARE\Microsoft\Microsoft SQL Server\Instance
Names\SQL"
Value="MY_DBINSTANCE"
Result="exists"
Win64="yes"
Variable="SqlInstanceKeyFound_x64" />
but this obviously isn't what I need and if I substitute the hard-code
instance with my variable "[txtDBInstance]", the registry search looks for a
value of "[txtDBInstance]" and NOT the value contained within the variable
("MY_DBINSTANCE").
I've tried using something like :
<?define InstanceName = [txtDBInstance] ?>
and used InstanceName in the registry searches, but that too does the same
thing i.e. the InstanceName variable contains a string of "[txtDBInstance]"
and not "MY_DBINSTANCE".
So how do I pass values gained from an EditBox into the Value attribute of a
registry search ?
Cheers,
Chris.
