hi,
i was writing my own installer program for my app, but i ran into a
roadblock.i need to copy over directory trees which contains both files and
directories. i am using pure win32 (no OWL or MFC) and there is no
CopyDirectory (). there is a CopyFile (), but the tree that i want to copy
has a lot of files and i don't want to do it that way. plus when i add a
file to the tree i wil have to remember to update the intstaller. i was
wondering if there is a good way to do this? the only other way i could
think of was to spawn a new process and call xcopy to do the directory copy.
any ideas?
aloha,
mike
 

While ShFileOperation might be able to do a deep copy of everything in
a directory tree that is when it copies from one place on the disk to
another. It does not accept a list of things to create.
The underlying operating system has no facilities for creation of the
set of items. Each directory and each file is individually created.
It is a reasonably easy task to cycle through and create each.
Just make a set of functions or a class which scans a directory tree
and assembles the file and directory names along with the file sizes.
Make a copy of that set of functions and have it create that same set.
Now you not only have the creation function but you also have
something that will automatically add the new file you've put into the
original directory tree to the list it finds.

Mike:
I suggest you to take a look at Inno Installer: www.jrsoftware.org
It solves the most case of installation (even includes presets for typical
setups, ie: BDE, VBS, and others).
If you need more control it allows to call a DLL or use InnoScript (a Delphi
based language).
Inno was choiced with several awards and by last but no least: it's free.

want a function to copy whole directories, I have a set of functions that I
wrote a long time ago to do just that:
bool CopyTree( char *SourceDirectory, char *TargetDirectory );
bool DeleteTree( char *SourceDirectory, bool bEraseReadOnlyFiles = false );
bool MoveTree( char *SourceDirectory, char *TargetDirectory, bool
bMoveReadOnlyFiles = false );
Let me know if you are interested in having these, and I will gladly post
them to the attachments newsgroup. They are written entirely with the Win32
API (no VCL) because they were written for VC++. I also found the code
below with a google search. It's Delphi, but it would be a fairly easy port
to C:
function CopyTree(dir, dest: string): Boolean;
var
sfos: TSHFileOpStruct;
begin
FillChar(sfos, SizeOf(sfos), 0);
dir := dir + '\*.*'#0;
dest := dest + '\*.*'#0;
with sfos do begin
wnd := 0;
wfunc := FO_COPY;
pFrom := PChar(dir);
pTo := PChar(dest);
fFlags:= FOF_ALLOWUNDO or FOF_RENAMEONCOLLISION or
FOF_SIMPLEPROGRESS;
fAnyOperationsAborted := false;
hNameMappings := nil;
lpszProgressTitle := nil
end;
Result := SHFileOperation(sfos) = 0
end;

Dennis,
That would be a tremendous help. could you please post it?
Aloha,
