Hi all,

How do you send keystrokes to a console application?

Occasionally, when I try to open a file for writing, I get error code
1224 (ERROR_USER_MAPPED_FILE). The full text corresponding to this
code is "The requested operation cannot be performed on a file with
a user-mapped section open."

This condition only occurs once in a while, at a couple of the 2000
or so installations where this program runs (under Win2K or XP).
There's nothing special about the file; it's a text file containing...

From a compiled C program, I'd like to spawn a compiler, supplying it with
command-line arguments and standard input, and capturing its standard output
and standard error streams. (Without using intermediate files--direct
communication between parent and child processes.)

Where can I find examples or a tutorial about how to set this up and do it?

I know it would have something to do with pipes, but I'm not sure of the
details.

Thanks.

Correct as far as it goes, but that's not the complete set.
Overlapped I/O is beneficial when there's *anything* other than waiting
for the I/O you just started that you could be doing before it
finishes; that can be running other I/O operations in parallel, but
there are other things you can do as well, like processing data you
already have or waiting for events other than an I/O completion.

Hi,

I'm using the CreateFileMapping( ) function to do the obvious and
everything works as expected on my XP development machine. However,
when I copied the binaries to a Vista machine CreateFileMapping( )
fails and GetLastError( ) returns error 5. I looked on MSDN and see
that system error 5 (0x5) is ERROR_ACCESS_DENIED.

Now, I'm calling this to create a shared memory space in the system
paging file. As far as I know, the user running the process on Vista
has administrator rights but to be honest I'm not fully sure of that.
I can't seem to find any place to make sure that this user is the
Administrator (or equivalent). I'm not able to login as the
Administrator user (not even prompted to, all I can do is click on the
Jedi user I created at install time). To be honest, with exception to
some useful changes to Windows Exploder, I'm not at all impressed with
Vista, but that's another conversation altogether.

If it's not because of the user id, what else causes access rights
violations when attempting to use the system paging file with
CreateFileMapping( )?

I can't get vs2005 to produce .lib and .exp files when I build my
DLL.
What do I have to do to persuade vs2005 to write these files?

I have seen that the project was set up with:

Import Library $(TargetDir)$(TargetName).lib

And I have tried adding to the linker command line:

/IMPLIB:"c:\TPCAgent\Debug\TPCAgent.lib"

What else must I do to generate .lib and .exp files for this DLL?

I have what I believe is an identical project elsewhere that /does/
produce the .lib and .exp files I want.

Thanks!
