Instead, load the extractor into a TMemoryStream, attach streams of the resources to the end of it, then add pointers to the end of that to the start location of each resource. Have the main extractor read itself into a filestream, get the pointers for each individual resource, and extract them back out. Pretty simple actually, and appending to the end of the main file doesn't break the executable. -Tony _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
[lazarus] Making an installer
Is it possible to have files in laz-resources, and to drop them to HDD at the run-time? Also, some kind of compression-decompression would be also welcome.

Thanks, that was useful.
Do someone know, do LazRes uses some kind of compression and/or encryption?

It does not. You must do that on yourself.

I have no experience with compression/decompression . Apart of that, the problem I have asked here depends on compiler, so it isn't suitable for deployable fully-featured installer. Only situation where this will be suitable for me in the future is: - I prepare a HTML documents that is a help-file for my app - I prepare a little app that will takes arguments and depends on them it will open different HTML documents in default browser - All this is unpacked on runtime when user clicks HELP in menu - after viewing the help, those (app and HTML documents) are deleted from the HDD bobby _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
