Installscript: Howto set targetdir for script-created features?

[UNeverNo]

I need to install dynamically features depending on the data found in my sourcefolder, e.g. I have two folders apples and cherries:
SOURCE\apples
SOURCE\cherries

Now the user should be able to chose which feature he wants to install. Depending on his choice I want to transfer these folders to a certain folder each:
TARGET\1\apples
TARGET\2\1\cherries

I was able to add my script-features by using FeatureAddItem but now I need to bind a folder to that feature and set the targetdir. How do I do this?
I tried manipulating OnInstalling, but unfortunately the szFile is no byref-variable, which means I can't change the targetdir 😞
And if I use OnInstalled (to move the files) it would be a kind of "temp-folder which needs to be deleted in the end"-solution, which I don't like much.

How are you actually transferring the files associated with the script-defined feature? Could you borrow FEATURE_FIELD_MISC or the like to store the fake destination location?

[UNeverNo]

Hi Robert,

they get transfered, because they are part of a feature/component which is not script-generated. I now set the targetdir to supportdir and copy my files to the real targetdir. But I somehow don't like it 😉

FEATURE_FIELD_MISC won't help, because I can't bind the folder "cherries" to that script-based feature and therefore the info in FEATURE_FIELD_MISC is useless.

[RobertDickau]

Sorry, I'm not sure how the real features/components and the script-defined features are connected? How are you copying files from SUPPORTDIR to the real TARGETDIR?

[UNeverNo]

There is a real feature and a real component, which has a dynamiclly linked folder.
During runtime I read an ini-file included in SRCDIR, which contains all modules. With these information I create these script-based features and show them to the user. Now he can select what he wants to install. But at this point I can bind a folder to the feature (a folder which is inside the mentioned component). If I could perform this, it would be possible to deaktivate the normal feature and just install the folders binded to the script-features.

But because this doesn't work, I need to copy each file in OnInstalled and delete then the TARGETDIR which pointed to a temp folder.

Hope that was a bit clearer 🙂

Is it an option to use only script-defined features, and then use XCopyFile to copy the corresponding files directly from the source to the destination?

[UNeverNo]

That's what I do now. But I don't like it much, because I copy all files twice.

[RobertDickau]

I mean, is it an option to copy the files directly from the source to the target without the "real" feature and component?

[UNeverNo]

Yes, but how will I manage that? There will be no events if there is no real component containing my data. Or what do you have in mind? 🙂

[RobertDickau]

You should still be able to use events in general when doing file transfer with XCopyFile. (Not feature events, of course.) Was there something in particular you're unable to do?

[UNeverNo]

What events are you talking about? I can just go through my dialogs and after pressing "Install", waiting for the standard events to occur, or am I wrong :confused:
