I don't really do C# programming. However those nice Wix people have already
done it for you.
Look at the DTF help file in Wix for the ComponentInstallation class.
Something like new ComponentInstallation("<your component
code>").Product.Features would enumerate your installed features.

Subject: Re: [WiX-users] Identifying Features that have been installed
Hi Peter,
Really appreciate your feedback on this.
The MsiGetEnumsFeatues() is defined as
UINT MsiEnumFeatures(
__in LPCTSTR szProduct,
__in DWORD iFeatureIndex,
__out LPTSTR lpFeatureBuf,
__out LPTSTR lpParentBuf
);
So to get the product code, I found this code
[DllImport("msi", CharSet = CharSet.Auto)]
static extern int MsiGetProductCode(string component, StringBuilder
buffer);
public static string GetProductCode(string component)
{
StringBuilder productCodeStringBuilder = new StringBuilder(512);
switch (MsiGetProductCode(component, productCodeStringBuilder))
{
case ERROR_SUCCESS:
return productCodeStringBuilder.ToString();
// *Please* don't actually just throw an exception like
this.
// Throw the relevent exception based on the error code
returned.
case ERROR_BAD_CONFIGURATION:
throw new Exception("The configuration data is
corrupt.");
case ERROR_INSTALL_FAILURE:
throw new Exception("The product code could not be
determined.");
case ERROR_INVALID_PARAMETER:
throw new Exception("An invalid parameter was passed to
the function.");
case ERROR_UNKNOWN_COMPONENT:
throw new Exception("The specified component is
unknown.");
default:
throw new Exception();
}
}
The problem is thay symbolic constants in the switch statement (eg
ERROR_INVALID_PARAMETER which are uints) aren't recognised so error on
compile.
Do you know how I can resolve these. I'm assuming there might be an Enum for
them but I can't locate them.
Again any help would be appreciated.
Regards,
Anil.
