This was a simple, plain text format that just had the text of every message. The separator between messages was a line that read "From Sat Jan 07 11:14:59 2023".

If you upgraded your display as well, the problem is probably the display scaling. Unless you mark your application has being "high DPI aware", Windows will lie to you about pixel locations.

You are trying to run the Excel application. To do that, you have to
have Excel installed on the machine where you're running. And, of
course, nothing that uses Win32Com can ever work on Linux.
If you're trying to manipulate Excel files, there are many

No. Just like a Windows GUI app, a Windows service has a main message
loop that has to remain in control, so it can receive and dispatch
messages from the service manager. The system sends "are you awake?"
messages periodically to make sure you're still alive. If you aren't
getting back to the main loop, then you will be terminated.
So, if you're using the sample you mentioned, the service "def
main(self):" will need to launch a thread to do your listening. You will
also need to have your thread check the "stop_request" flag, so you can
cleanly exit when the service is terminated.

What do you mean by "it does not work"? Do you get an error? Does it crash?
Have you read the documentation for the SolidWorks API? As I read the
documentation, the API for running a script is called RunScript, not Run.

My ignorance of C++ and the Windows APIs and hell the Python C API is really biting me here. 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. 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. 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.

To see what it looks like in a chunk - What you HAVEN’T said here is how you are talking to Outlook — how you generated your “outlook” object. PyWin32 doesn’t have any code that is Outlook-specific. I assume you’re using win32com.client.Dispatch. If so, remember that Python isn’t doing any processing here. It’s just passing requests through COM to Outlook. If your text is coming back oddly, then Outlook is returning it oddly. tags are intended for web servers; it’s possible that Outlook is absorbing the tag because it isn’t useful. Maybe it has copied the charset to a property of the message object to reflect the character set. That is, perhaps there’s something in the “item” object that gets tweaked. > Because the emails otherwise are identical, I can only assume this is being > done by the library.

I am trying to open a memory mapped file using Python. I originally

The file size isn't really "unknown". It's just not known in advance.
There are many ways to find the size of a file. Plus, the "mmap" module
accepts 0 as a size parameter, meaning "map the whole file".
I am now using the "mmapfile.mmapfile" function. My code looks like
this <https://pastebin.com/QygT2wp6>. In the docs
<http://timgolden.me.uk/pywin32-docs/mmapfile__mmapfile_meth.html> it
says I can use a file name of "None" if I'm planning on opening an
existing file. This <https://pastebin.com/2FVhpDiB> is the error I get
when running my code.
There are a couple of misunderstanding here. It is important to realize
that the name of the mapping object is quite different from the name of
the file being mapped. The Windows memory-mapping concept is quite
general, and is often used as a way to share memory between multiple
processes. In that case, you just want a chunk of memory without
bothering with a file on disk. In that case, you'd create a mapping
object with a name, but no file name.
If you're just mapping an existing file, you need to supply the file
name, but you don't need to supply a name for the mapping object. The
code you showed creates a shared memory object that does not map a file
on disk. The shared memory object has a name (the GUID), and another
application could open that named object, but it doesn't map to a file.
If you want to open a mapping to an existing file, specify the name of
the file as File= and specify Name=None.
However, you can do all of this with the mmap module as well. If you
have a file called "data.bin", you can do
import mmap
fn = open('data.bin','rb')
data = mmap.mmap( fn.fileno(), 0, access=mmap.ACCESS_READ )
That maps the whole file, and len(data) will tell you how large it is.

The last parameter is the size of the output buffer, and that does get passed
to the driver. It should be sizeof(VOLUME_PROPERTIES_STRUCT) which is, I
believe, 1280.

The first b’0x00’ is wrong; the first byte of the struct needs to be 5.

Usually, with a COM server, the bit size of your Python must match the bit size of your COM server. So, you'd need to use 64-bit Python to call a 64-bit COM server. (Note thet pywin32 is available for both 32-bit and 64-bit Pythons.)

GetMathUtility is a method, not a property. You need to call it as a function:
mathUtility = swx.GetMathUtility()
ActiveDoc is a property, and so should not need parens.

Nope. Remember that win32crypt is nothing but a thin layer that calls the Windows CryptProtectData API.

It is a C API, and it expects to be handed the address of a C function in the other process. id(x) returns to you an address, but it’s an address that has to be interpreted by the Python interpreter run-time, and the Python run-time will not be part of the other process.

I am under the impression that most people shipping Windows Python applications do so using something like Pyinstaller or Py2Exe, which packages up something that looks to the end user like a single executable, but which actually contains a zip file with the necessary modules and DLLs. The zip file only contains the parts of pywin32 that are actually required by the application.

Pywin32 simply makes all those thing available to you. You don’t have to use them. And if you aren’t using the graphical interfaces, then you aren’t shipping them. The Python installer apps only include the things your script needs. If you don’t need graphics, then graphics DLLs won’t be included in your package.

Well, yes. There are rigid rules for writing IDL to make a valid dispatch
interface, and generic structs like that are not in those rules. Some people
get the idea that anything they can express in C++ can be shoved in a COM
interface, but it ain’t so.
You should be able to add a GUID attribute to the IDL:
[ uuid(12345678-1234-1234-1234-123456789ABC) ]
typedef struct SoftwareInfo {
…
} SoftwareInfo;
Just generate a new GUID for each one.

The VT_CY type, the Python decimal type, and the C# decimal type are all the
same — a 128-point fixed point value with 92 bits of precision. That’s
probably what you should use. In order to use VT_DECIMAL, then you probably
can’t use automatic translation.

By default, that will create a “single-threaded apartment”, where actions get handled by a single thread. You can try calling CoInitializeEx with COINIT_MULTITHREADED and see if that helps. But even then, you bang up against the Python interpreter lock, which only allows the interpreter to handle one thread at a time.

The Python part is now working. WE have no way of knowing what your

The error is pretty much self-explanatory; you're trying to pass the value of the variable "actionScript" to the DoAction function, but there is no variable called "actionScript". Look at the code itself. You'll see that "actionScript" was passed in to the function as a parameter, because he wanted to be able to trigger different actions with the same code. It should be clear that what you need to pass here is the action you want to take. However, if you really need to script common actions to images and folders, I strongly suggest you take a look at the ImageMagick package.

I TOLD you what is wrong. Let’s follow the flow. Every 8 seconds you call
listener. It does the following, very quickly:
* Fetch the window under the cursor, assuming the cursor is over a window.
* Create a Python window object around that window handle
* Install a hook to catch button down messages for that specific window
* Function exits, the window object is destroyed, and the hook is uninstalled
Then you go back to sleep. While you are alseep, there is no hook. The only
time you have a hook is the few milliseconds between your HookMessage call and
when the function returns.
The right answer is to use a package like pyHook to install a global hook.
This is exactly what it is for.

Your code came across badly formatted, so I can't tell exactly what you
wrote. You aren't actually calling listener() from within a continuous,
tight CPU loop, are you? This function is going to get called thousands
and thousands of times a second. This is very poor practice, and it's
part of the reason these other modules exist.
You attach to an external window, install your mouse message hook, then
your function exits, the window object is deleted, and the hook is released.
