QUESTION
I'm trying to write an app to perform some basic process automation by sending keyboard events (i.e. simulating single key presses as well as holding keys down) to a window in focus (any window, such as Notepad). I can get single key presses to work just fine, but I can't get it to hold a key down. Even if I do a key down event, followed by a lengthy delay, followed by a key up... all I get is a single keypress.
I've read so many tutorials, and many of them multiple times over to ensure I haven't missed something. Every single time however, all I get is a single key press, it fails to hold the key down.
The following is a code sample I found from: https://social.msdn.microsoft.com/Forums/vstudio/en-US/bad5b1f3-cf59-4a2b-889b-257ee590bf99/vb-advanced-key-bot?forum=vbgeneral
What I'm expecting to have happen is that it would send a keyboard event that tells the system to hold down a key (e.g. aaaaaaaaaaaaaaaaaaaa), but all I get is a single character. I've tried spamming the system with repeat keypresses, but the receiving app sees the different keyboard code for keydowns and keyups, as opposed to a key in a held status, and thus is not responding as though the key were actually held key down.
What am I doing wrong? Did they maybe change this dll?
A huge thanks to anyone who can help me get this working.

Answered 2022-Apr-12 at 01:36Answering my own question after going right down the rabbit hole on this one.
Basically put, the only way to do this is with SendKeys. The other methods are all deprecated and so will not work in this way anymore.
However this isn't a dead-end for you. If you want to use SendKeys to "hold down" a key, then spam the key at 10ms intervals and this should trigger the receiving app to think the key is held down.
QUESTION
Using Access 365. I would like help building code to achieve the following please, I’m trying to streamline adding images to a record.
I would like to use VBA that on clicking a button will save an image as a .jpg from the clipboard (put there by User using Snip tool) to a subfolder of the database, then pass a relative link to this file to the form. I’d like to be able to attach multiple images’ links to a given record in this manner.
Using the code below (without the AltPrintScreen element) I’ve gotten as far as saving from the clipboard and generating an absolute link, but only as a .bmp. (https://www.access-programmers.co.uk/forums/threads/print-screen-into-image-file.245198/). Grateful for any help getting the rest of the way, or suggestion of an entirely different way of doing it. Cheers!

...ANSWER
Answered 2022-Mar-08 at 20:38I've created a solution that does what I want. I've used four Modules I found on various sites and then created a bit of VBA to pull the tasks together in the background.
- Module 1 is the one I posted in the question above. I bypass the AltPrintScreen part of it so it doesn't overwrite the image already in the clipboard.
- Module 2 Converts the BMP created by Modules 1 into a JPG.
- Module 3 Scans a folder and populates an unbound listbox with a list of the files found there.
- Module 4 is used to make the filepaths in the listbox act as hyperlinks to open the images on clicking.
I then created a button on a form that calls the first two Module to create a jpg from the image in the clipboard as follows...

QUESTION
So I am working on some code to randomly send keypress's through Virtual Keys after a random timeframe (5-10 seconds is just for testing purposes). I'm trying to add Clock.schedule_once, but with how I have things right now, it is firing off every second because it's stuck in a while loop. I've been wracking my brain around on this one trying to figure out how to implement this properly, but I can't seem to come up with something, so I am reaching out to you guys to see if you can provide any input on possible solutions to this.
...ANSWER
Answered 2021-Dec-29 at 00:46In general you should avoid using time.sleep() in kivy app, because it freezes event handling routines.
Here is my proposal based on two scheduled jobs. In short key pressing job is scheduled once after random time and it reschedules itself indefinitely. Second scheduled job is responsible for stop key pressing job.

QUESTION
I wanted to make a macro that sends space infinitely only if I press it, the problem is that it's sending it even after I left my finger of the button.
...ANSWER
Answered 2021-Oct-04 at 22:36You have to check the most signifcant bit of the return value of the GetAsyncKeyState() function to determine if they key is currently pressed or not.
If the function succeeds, the return value specifies whether the key was pressed since the last call to GetAsyncKeyState, and whether the key is currently up or down. If the most significant bit is set, the key is down, and if the least significant bit is set, the key was pressed after the previous call to GetAsyncKeyState. However, you should not rely on this last behavior;
Simply, it means that GetAsyncKeyState() returns not just true or false, but a wide range of values. To determine if the key really is currently held down, aka pressed, you need to use a bit-wise operator with the value 0x8000.
Example to check if the Space key is currently held down:

QUESTION
I am using a voice recognition add-on to Dragon NaturallySpeaking to create keystroke automations using my voice. The add-on exposes the VB function SendKeys. I am aware that the shift key modifier (+) can be combined with almost any other character(s), but I am not trying to combine the shift key with anything; I simply want to send a single shift keypress without anything else. Is this possible?
Some things I've tried:

Answered 2021-May-04 at 13:53So it turns out that I could substitute the Integer type for the UInteger type. Then I had to figure out how to eliminate the CByte call and the System.Windows.Forms.Keys enumeration. Lastly I just removed the unnecessary Module declaration and everything seems to be working perfectly now. And yes I did repeat the key up and key down events because I actually wanted to hit the shift key twice. Thanks to all who tried to help.
QUESTION
The bulk of my work is performed via a Remote Desktop Connection. I will often listen to music on my local machine while working. I know this is a small thing but when I need to Pause my music I must first minimize my RDP session so that my keyboard macros will be applied to the local machine and not the remote machine.
I tried creating a simple c# application that will simulate the key presses for play/pause, next, previous but this doesn't solve my issue because it is still simulating a key press. My question is how can I control my music on my local machine without minimizing my RDP session?
Here is the code I am currently using, maybe I need a different approach?

Answered 2021-Mar-16 at 15:01I ended up getting the handle for my computers Desktop and passing that in the keydb_event.
