Re: [WiX-users] Creating Unique GUIDs inside a foreach block?

[Pound, R. (CDC/OCOO/I. (CTR) <uw...@cd...>]

I like this option.

However, when I try using syntax: Guid="$(var.Guid.$(var.ENVIRONMENT))"  I get a error "Undefined preprocessor function '$(var.Guid.$(var.ENVIRONMENT))'.  (note I have also tried syntax
'Guid="$(var.Guid$(var.ENVIRONMENT))"  ' , no period between Guid and $(var.ENVIRONMENT)

When I change the syntax to:  'Guid="$(var.Guid.Development)" '
it finds the preprocessor variable.  I have determined thru testing that ENVIRONMENT is set properly and that GuidDevelopment, GuidTest, GuidQA, and GuidProduction preprocessor variables are set correctly.

I also tested defining a variable using a variable in a variable syntax 
('<?define myGuid="$(var.Guid.$(var.ENVIRONMENT))"?>') and received the same error.

Thanks,
Bob

The guid autogeneration is based on the keypath including directory path
from a well-known directory. What you have is several components, all of
which have the exact same directory, and ending in the exact same filename.
Given that, they will all get the same auto-guid (that way, they are
stable).

You must change either something in the directory (path), or the filename,
to get different guids, if you wish to use autogen guids.

If you absolutely require the same filename in the same directory, you will
need to generate your own component guids for each environment.

As an example, if you have defined Environment1, Environment2 and
Environment3 as your values in your ENVIRONMENTList and
GUID1, GUID2 and GUID3 are three different guids you generated for those
three components:

<?define Guid.Environment1=GUID1?>
<?define Guid.Environment2=GUID2?>
<?define Guid.Environment3=GUID3?>

You can start your example code like this:

<?foreach ENVIRONMENT in $(var.ENVIRONMENTList)?>

<Component Id="InstallConfig.$(var.ENVIRONMENT)"
Guid="$(var.Guid.$(var.ENVIRONMENT))">

Subject: [WiX-users] Creating Unique GUIDs inside a foreach block?

I'm using VS2010, WiX version 3.6.1112.0.

The following snippet of code is used to generate a 1-n # of components,
based upon value of EnvironmentList variable.  It works ok with 1 entry in
EnvironmentList.  However when EnvironmentList contains 2 or more entries I
get an ICE08 error on the component  stating that it has a duplicate GUID.
It seems that the Guid="*" is not creating a new GUID on each iteration of
the foreach loop by the preprocessor.   In this scenario, how can I generate
a unique GUID for use within a foreach loop?

<?foreach ENVIRONMENT in $(var.ENVIRONMENTList)?>

<Component Id="InstallConfig.$(var.ENVIRONMENT)" Guid="*">
<Condition><![CDATA[USENVIRONMENTCONFIGFILE = "yes" AND
PROP.INSTALL.ENVIRONMENT = "$(var.ENVIRONMENT)"]]></Condition>

<File Id='file.config.$(var.ENVIRONMENT)'

Name='web.config'

Source="$(var.SourceDir)web.config.$(var.ENVIRONMENT)"

DiskId='1'/>

</Component >

<?endforeach?>



Thanks, Bob
