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

It is done: http://sourceforge.net/project/showfiles.php?group_id=158815

Check the release notes or the readme.txt for (much) more information.
Version 1.0 (the first stable one) will fix certain behaviours, but it
should not break anything. 

I will probably update the web site when I have the time and move
documentation (or at least some tutorials) in there.

Hello all,

The next release is almost ready, but because I am not available during this
weekend I will have to delay it for a few days. It should be available
before next Wednesday if everything goes well.

After some investigation I noticed that the COM-object responsible for the
rendering ignores spaces (and probably some other whitespace too) when it
renders the text. They are rendered, but they don't increase the width of
the string. The getTextSize() uses normal Windows API and it does count
whitespace, so there is some difference between the results. So the more you
have whitespace in the string, the more the results will differ. There
really is no fix for this because I can't modify the underlying COM-object.
Fortunately the "do it yourself" method (EditBox etc.) is not affected by
this, so if you implement a similar solution it should work OK. You can also
count the whitespace in the string and make an educated guess about how much
you should tweak the resulting width in order to get better results.

Subject: Re: [DirectPython] I am back


Hi Heikki!

Great!
We're almost crying... (not seriously  =3DP).

But like other users, I found that directpython is one of the best =
modules
for python that I've never seen before. =3D)
Thanks for this module. =3D)=20

I've just one suggestion, and that is:
Can you can include some kind of "virtual filesystem" to DP?
I mean a virtual filesystem based on zlib or something like that.

I know it's not up to DirectX but resourcepackager is a messy way to =
package
our resources (I don't like to write the files down to read them).=20

Thanks,
And sorry for the troubles.

Hi,
=20
I don't think that creating a virtual file system is very high on my =
list of
current tasks. Sure, it could be useful but I don't think that most =
people
really need it. Simple system is relatively easy to implement with the
zipfile-module, but the advantages are not that great. It is harder to =
use
during the development and slower than the native filesystem. C++ side
support for this filesystem would be hard to implement because many
COM-objects use the normal filesystem no matter what. You would have to
unpack the wanted file to a temporary directory when you want to create =
d3d
objects from the resources. With large amounts of data (meshes, =
textures) it
would be quite wastful.
=20
If you really want to do it, zipfile has pretty good support for things =
like
that. It does not take much time to implement simple loadfile() and
savefile() calls which maps the file path to the actual file stored =
inside
the .zip file.

Hello all,

It has been a long time since I have had much time for DirectPython, but now
most of the time consuming work is over and I can start to properly maintain
this project again.

The next version will be 0.9 and it will be the last beta version. Certain
things have been fixed or changed during this long break, but most of them
should not affect existing code. However, there are some things that will.
Here is a current list:

-d3dgui received a major update. Expect to change some of your code. There
will be a backwards compatible version available too, but who wants to use
that when there are new fancy things available? :)
-d3d.Effect.update() was changed as previusly mentioned, it will only accept
one dictionary argument.
-Certain fixes might theoretically affect old code, but testing has not
noticed anything major yet.

There are also some new things:

-Matrix class added (uses D3DXMATRIXA16 for those who are interested)
-Basic support for render targets added. 
-Samples added:
	-rag dolls with PyODE 
	-post processing 
	-Biovision motion (.bvh) file viewer 
-Many samples were updated
-Some tutorials.

You can still say if you need any specific functionality, if it is generally
useful it can be added. The next version will be release when it is ready,
altough I have no idea when that is. A month (give or take a few days) from
this day might be a good guess.

Hi,

The height which font.getTextSize() returns is always the same and line
breaks don't actually increase that value. The common thing to do is to
split the message into words and then calculate line- and wordsizes so that
it fits into the wanted area. In short, draw many rows instead of big text
blocks. This also makes sure that the message is always properly formatted
and fits into the screen. For example d3dgui.EditBox and tooltip creation
use this method. For trivial uses it only takes few lines of code to do
this.

Hello,

I am making a program which uses direct python to scroll messages across 
the screen.

I need to calculate how many pixels the message is in height.
I have tried many ways, but it seems that the font.getTextSize function 
does not return the actual size.

I am using "font.getTextSize" to get the size, and "d3d.DrawTexts" to 
display the text.

Any help on this would be much great, thanks.

David Mack

Hi Sebastian,

=20

Thanks for the information.  I've added them to my list.=20

=20

I haven't actually distributed the package yet, so I haven't looked into =
the
problem about the .NET package. I'll get back to you as to what happens.

Subject: Re: [DirectPython] More DirectPython Examples

Hi Gavin,

These are just tools that I've used for a game:
-To make your resources unavailable to any user use "resourcepackage" (I
don't remember what was the site of this package).
-And to speed up your programs you can use "psyco" (
http://psyco.sourceforge.net/).
-py2exe

I didn't remember any other tool.

BTW,
I didn't use DP with IronPython but when you make the Installer for your
game...=20
Did you have to include the .NET Framework?

I'm asking that because if your game it's just about 5 Mb and the .NET
Framework it's about 30 Mb then the user must download 35 Mb and that =
makes
nonsense.=20

There is no direct way to do this in DirectPython. You can render the =
scene
and then use d3d.getScreenshot() to get the results, but this is pretty
slow. It is possible to use DirectX for comtypes for this, but you need =
some
Direct3D COM-programming experience.
