Hi,

It is not supported by DirectPython, but you can do it if you have ctypes
installed (Python 2.5 has it by default).

See http://msdn2.microsoft.com/en-us/library/ms646310.aspx for MSDN
documentation about SendInput(). It looks more complicated than it really
is, but some basic ctypes tutorials should be enough to understand it if you
are not familiar with C or C++.

You need to declare some structures and understand what they represent. You
probably only care about the INPUT and KEYBDINPUT structures, but you have
to declare MOUSEINPUT and HARDWAREINPUT (because of the union in INPUT)
altough you don't need to know much about those two.

Alternatively you can use PostMessage() (with ctypes), but that is not
reliable. But if you just hacking something together, it might be enough.
Just don't use it in real production code. However, before you can use that
you must figure out what your target window is. Get the handle by using
FindWindow() (ctypes again) or something similar. 

You can also use Win32 Extensions for Python (win32all) to access these
functions. It is easier, but you need to download additional packages. 

As you can see, there are many ways to archieve what you ask. Check them out
before you decide.

Hello, I just need a quick answer before proceeding further...

Is it possible to send virtual key strokes with directpython to a window
so I can finish a voice control program i'm writing in Pyhton?

Cheers!

Well, the simplest way I can think of is to install DirectPython into a
computer where you have admin access (home, friend, co-worker etc.). Then
copy the files from there and create your .zip "installer" using those files
or move them around using some other way. Not very elegant, but you only
have to do it once. All those .dll's you listed except "d3dx9_30.dll" are
core Direct3D 9 files which are present in all system which have DirectX
9.0c installed. Remember, you only need the "d3d.pyd" and "d3dx9_30.dll".
The latter is not often present on many systems, it is put there by the
installer. You can also find "d3dx9_30.dll" from the net (www.dll-files.com
for example), but make sure that the .dll really is what it says it is.
Trojans can be nasty things.

I have also modified the installer to allow non-admin install, but that only
applies to future releases.

The suggestions about copying DLL's are good but it
does not solve my problem: where can i get hold of
those files. There are only 2 installers: a .exe and a
source distribution with cpp files. In no way am i
able to grab the necessary files.
Another remark: my system32 directory contains the
following files already:
d3d9.dll
d3d8.dll
d3dim.dll
d3dxof.dll
d3dramp.dll
d3drm.dll
d3d8thk.dll
d3dim700.dll
d3dpmesh.dll
but no d3dx9_30.dll

Anyway, i believe you got my message. Further adoption
necessitates an easy way for casual users to
experiment.

Best regards

Alain

Hi,

As David noted, it is possible to just copy certain files to a place where
they are found by Python and Windows DLL loader. Administrative privileges
are needed because certain D3DX dll's are installed into the system32
folder. However, this step can be ignored if the dll's are already installed
(by another application or from an installer provided by Microsoft).

I will list here what it needed.

Absolute minimum requirements (for DirectPython 0.9):
-Direct3D 9.0c installed. No way to ignore this. 
-D3DX dll (see d3dc._d3dx9dll, currently "d3dx9_30.dll"). This is in
system32, but you can also put it in the same directory with d3d.pyd
-d3d.pyd (the main DirectPython runtime .dll)

So, you actually only need to distribute two files. However, the D3DX .dll
should not usually be distributed like that (use the installer in
directpy\redist - all those files in there really install only one .dll),
but you can if you have no choice. You can also try to get your system
administrator to run the setup, as it is signed and approved by Microsoft. 

The easiest way to make a custom "installer" is probably just to create a
.zip file which contains the tree structure and required files (you can drop
samples or anything else you don't need). Then unzip it into the
PythonXX/Lib/site-packages/directpy-folder (or any other folder, just make
sure that is it in sys.path). The real .exe installer does nothing very
important, so you can safely ignore it.

In short, put "d3dx9_30.dll" and "d3d.pyd" into a directory which is in
sys.path. Then try to run a Python script:

"import d3d"

It should work. Then just add what you need (like d3dc.py, d3dx.py etc.). 

I can (and probably will) change the installer to work with normal users,
but the D3DX issue will still remain. But at least it allows people to solve
it in a way which suits them best.

Hi,

I had that problem also, so I went to a computer with Direct Python 
installed and copied all the dll files it needs and all the modules (and 
the directpy.pth file) for directpython in the site-packages folder 
(inside the Lib Folder of python's install dir), then put the dlls into 
the dlls folder in python's dir on the target computer, and the other 
modules (and the directpy.pth file) into the site-packages dir on the 
target computer.
I probably took more dlls than were needed but when I did it I was in a 
rush.
Im sure someone can make an install, but this a quick solution.

Some of the dlls you need are in the system folder, and since python 
loads dlls from its dlls folder as well the system folders you it works 
to copy them to python rather than the system folder (which you might 
not be able to do anyways).

Good Luck

David

Hello,

I am new to DirectPython but i have a huge problem
that actually prevents me from using it at all.
The problem is: installing DirectPython requires
administrator rights on my machine, which i don't have
(this is a machine at work).
I believe this is a showstopper for most people who
would like to use DirectPython professionally.
Is there any change to see a DirectPython installer
that would install for the current user as a fallback.

Best regards

Alain
