If I have an app running on a Windows PC that is listening for clients
on a named-pipe (CreateNamedPipe in Win32), is there any way for a Mac
client to connect to that pipe?  From what I can tell, named-pipes on
Windows and Mac are very different things, and are not compatible at

    I had to re-install the 10.2 operating system.  Now if I try to run
Project Builder, it bounces on the dock a few times and stops, with no
error message.  I was using it successfully for months before this.  I
vaguely remember I had to edit a certain file to specify a path.  I

Is there a way to fix a file's counterpart? I had earlier done a save as
to move a file but the other side (of an .h, .m combo) points to an old
area (I've since commit'd and checked out the entire project).
I can navigate to the proper files from the project so it's just a

I've decided (hopefully well received) on using a popup button as a
multiple selection control. I use the item's tag values as a bit
position whose mask I keep in index 0; a user selecting this item clears
the entire mask while other item selections toggle that item 'tag' bit.

Hello, I'm a new Mac App Programmer used to Java and a little bit of C+
+, and I'm trying to wrap my mind around Delegates. How do they work,
what are they for, etc? Could anyone give me a basic run-down of them
and how to use them? Is an AppDelegate the same basic concept of an

I've got quite crazy idea - there's a wonderful button on a keyboard
named Caps Lock. And I really want it to toggle something useful -
like... ummm... keyboard layout? While switching keyboard layout isn't
really tricky, trapping caps lock - that's an issue.

Using 10.5 is there a way to access passwords in the keychain?

Hi all I have an app that has a UI on one display and a QTCaptureView
on another. The view has a live stream from a DV cam that I am editing
the frames of. What I need is for the view to be full screen without
the title bar on the top of the window. Is there a simple way to

Say, does anybody know of a Unix utility that lets me type in
attack/decay/sustain/release envelopes so I can port some of my old,
obsolete C-64 music programs over to the Mac?
Yes, that *would* make for a pretty strange Unix utility.

I have reinstalled my Mac (OS X 10.3.9) and propably forgotten, what I
have done to get this running:
c++ -c -g  -I .  dbTest.cpp -o dbTest.o

I have an NSTableView bound to an NSArrayController. The
NSArrayController is populated with NSDictionarys, each of which
constitutes a row in the  NSTableView. I also have two NSTextfields that
are bound to the selection of the NSTableView. When a selection is made

I am a Windows C++ programmer just cutting my teeth on XCode and Carbon.
What I want is a simple one line command to put up a message box printing a
given string with an okay button.
The equivalent of Windows MessageBox() function.

I'm trying to get my head around the very basics of the reachability API (as
suggested elsewhere). I found a wee bit of example code that I'm trying to
get working, but I'm having problems.
The code is essentially this:

ok, it was suggested to me that i shouldn't use copies of strings as i
do here

theString]];
