Subject: [python-win32] windows images on clipboard
Message-ID: <CAHWACcc49JfqPk1L9yBgdoPm=mizh7wGjzsCcy27RzRVkE1kcQ@mail.gmail.com>

I was looking at making a little helper app for Windows that will take an
image on your clipboard and ensure it is under 8MB for posting to discord,
and if it isn't, use Pillow to resize it until it is the right size.

I can use Pillow's ImageGrab.grabclipboard() to get the image off the
clipboard, but I am a little confused about writing it back. I have been
back and forth between the pywin32 source and the windows docs for the
windows C API, but I don't have any previous experience or context to know
what some pieces are intended to do.

I found an example to write to it from StackOverflow (
https://stackoverflow.com/questions/34322132/copy-image-to-clipboard), but
I was wanting to dig a little deeper to see what formats other than BMP I
could use to put on the clipboard. My ignorance of C++ and the Windows APIs
and hell the Python C API is really biting me here.

Is there a bit of an idiots example guide for how to say, put a PNG on the
clipboard or a JPG? Some example code? There is a ton of useful info in the
pywin32 repo, but I haven't found anything that has made this click for me.

Thanks for any help!
Andrew

You can't.? You have to write it as a DIB (Device Independent Bitmap), 
which is the format in a .BMP file.

The Windows clipboard was designed in roughly 1986, before GIF, before 
JPEG and way, way before PNG.? The clipboard is designed for universal 
interchange, so it really does need to spec the lowest common 
denominator.? If they allowed PNGs, then all of the graphics application 
in the world would have to be modified to decode PNG data.

So, to make your app work, save the result as a BMP.

There is no idiots guide, because it cannot be done.? Well, technically 
speaking you can put arbitrary binary data into the clipboard, but other 
graphics applications will not be able to read it.? When they look for 
image data, they look for format CF_DIB, and that means a .BMP.

Message-ID: <WC20210812091725.4703D6@agu.edu.tr>

Hello dear authorized,
I'm Salih from Abdullah G?l Univercity from Turkey. Now I'm tring to make a 
project with python and abap. I'm now using the pywin32 for com server in 
windows. I can send some variables to python from abap and get them. 
However, I have a problem with local variables. I create a String value 
before the methods and try to return these values in another method. I get 
the problem local variable 'xxx' referenced before assignment. I just want 
to take or change a variable that is not in the method. Please help me for 
this topic. If you want I can make more explanations. I used Stefan 
Schnell's page in SAP community.

	From a quick browse in Google -- IMAGES are only in one of the Windows
bitmap formats when on the clipboard; ie, they've been "rendered" to a
bitmap memory structure. PNG or JPG -- those are file formats, not rendered
images. There does appear to be a CF_TIFF format.

Awesome, thank you so much for that info. That makes my tail chasing make
more sense! Thanks for saving me from additional posterior extension
pursuit.

Last question I think, how do I put a file path reference on the clipboard
similar to in explorer selecting a few files and hitting control c ?

I think I had tested that with discord and it worked, but not 100% on that.

It sounds like you may want to store the value in an attribute
of an object instead of a local variable.

If you show us your code and the exact error message you're
getting, we will be able to help you better.

Message-ID: <15b6025f95e1c1b3bc82a5ec91e81b92.squirrel@c-true.co.za>

Hi there

I am specifically trying to sort out debugging code and processes when
working with the flask web development framework, while working with VS
code insiders.

Now, following things like the following steps, but, specifically using an
external terminal, I can get it to pause on breakpoints, etc. when
executing normal code, but, when trying to run it against the flask module
process, it seems to just execute the code and not manage to attach to the
execution processes, etc.?

Python and flask tutorial in VS code:
https://code.visualstudio.com/docs/python/tutorial-flask

Or, the more generic debugging implementation tutorial -

Getting started tutorial for python and VS code:

https://code.visualstudio.com/docs/python/python-tutorial#_configure-and-run-the-debugger

This is on a windows 10 64 bit pro machine, and, just want to know if
anyone has suggestions with regards to implementing debugging when working
with web development frameworks like flask, pyramid, etc.?

TIA

There are 2 ways to solve this task, actually.

1st way is a bit more difficult but more efficient.

Read https://docs.microsoft.com/en-us/windows/win32/dataxchg/using-the-clipboard#copying-information-to-the-clipboard and implement this in python module.



This was done for perl and worked for me in Win32::Clipboard module

https://github.com/jandubois/win32-clipboard/pull/5



At least worked for me (I haven?t rechecked but I am 95% sure it worked, I wrote perl script which rotates image in windows clipboard and placed rotated image back.

2nd way does not require C coding and deep delving into clipboard documentation

Tcl/Tk can do this.
You can use tcl/tk code from python with tkinter.

Awesome, thank you so much for that info. That makes my tail chasing make more sense! Thanks for saving me from additional posterior extension pursuit.

Last question I think, how do I put a file path reference on the clipboard similar to in explorer selecting a few files and hitting control c ?

I think I had tested that with discord and it worked, but not 100% on that.

You can't.  You have to write it as a DIB (Device Independent Bitmap),
which is the format in a .BMP file.

The Windows clipboard was designed in roughly 1986, before GIF, before
JPEG and way, way before PNG.  The clipboard is designed for universal
interchange, so it really does need to spec the lowest common
denominator.  If they allowed PNGs, then all of the graphics application
in the world would have to be modified to decode PNG data.

So, to make your app work, save the result as a BMP.

There is no idiots guide, because it cannot be done.  Well, technically
speaking you can put arbitrary binary data into the clipboard, but other
graphics applications will not be able to read it.  When they look for
image data, they look for format CF_DIB, and that means a .BMP.

Awesome, thank you so much for that info. That makes my tail chasing make more sense! Thanks for saving me from additional posterior extension pursuit.

Last question I think, how do I put a file path reference on the clipboard similar to in explorer selecting a few files and hitting control c ?

I think I had tested that with discord and it worked, but not 100% on that.

You can't.  You have to write it as a DIB (Device Independent Bitmap),
which is the format in a .BMP file.

The Windows clipboard was designed in roughly 1986, before GIF, before
JPEG and way, way before PNG.  The clipboard is designed for universal
interchange, so it really does need to spec the lowest common
denominator.  If they allowed PNGs, then all of the graphics application
in the world would have to be modified to decode PNG data.

So, to make your app work, save the result as a BMP.

There is no idiots guide, because it cannot be done.  Well, technically
speaking you can put arbitrary binary data into the clipboard, but other
graphics applications will not be able to read it.  When they look for
image data, they look for format CF_DIB, and that means a .BMP.

Subject: [python-win32] Troubleshooting with moving Outlook emails to
 subfolders
Message-ID: <d435e4d83c7f4f35bd230be50ef698ec@amundi.com>

Hello Mark,

I am stuck on this issue: https://github.com/mhammond/pywin32/issues/1743

I am trying to move outlook emails into subfolders and this works well most of the time.

However in some cases, probably when a copy of the email I am trying to move already exists into the subfolder, I get the error below using:
x.Move(self.folder.Folders("Inbox").Folders("VALORISATIONS").Folders("Allianz"))

Is there a way to specify that you want to eventually crush the existing email in the folder?

WSL is a linux environment - pywin32 simply doesn't work there. You can install it via a Windows command-prompt, or in WSL stick to the versions of Python that work for Ubuntu but without pywin32.

I'm afraid it's been over 10 years since I used Outlook's COM model. 
Hopefully someone else here will comment, but 2 observations:

* Search and delete for the mail firstt to see if the problem goes away? 
That will at least validate your hypothesis.

* Don't restrict your googling to Python - this issue will exist in all 
languages which use Outlook via COM and the subsequent solution will be 
identical.

Good luck,

Mark

Subject: [python-win32] Debugging python with something like VS code,
 when working with flask web framework
In-Reply-To: <1b14faee-2d1e-5958-7a8c-621d6a6902d0@blindza.co.za>

Side note - switching over to django instead of flask, and, debugging 
stopping on breakpoints inside VS code seems to work a bit better, but, 
along the lines of that, figured out that what might work a bit better 
from my perspective is using python's own breakpoint() function call to 
invoke [pdb] in the output console, where I can then type in querying 
code, etc., before then typing in continue and hitting enter to let code 
resume execution, and, if launching execution from within VS code, then 
I use ctrl + F5, to launch the process without it's own debugging 
initiated, etc.
