I have a PowerShell script that opens a file when you press a hotkey like: ctrl + alt + f so that the app automatically runs every time the user presses those key combinations.
Now, the problem is that it indeed opens the application/file, but it takes 4-5 second to process it. I want the process to be fast enough so that the script opens the desired files the moment the user presses the key combinations and not seconds after it. I don't know what caused this slowdown...
Here's the script:
# Get the Desktop dir. path.
$desktopDir = [Environment]::GetFolderPath('Desktop')
# Create the shortcut object, initially in-memory only.
$shc =
(New-Object -ComObject 'Wscript.Shell').CreateShortcut("$desktopDir\linkthis.lnk")
# Set the target executable (name will do if in $env:PATH).
$shc.TargetPath = 'C:\Users\abhay\Downloads\Test\script.py'
# Assign the hotkey.
$shc.Hotkey = 'Ctrl+Alt+F'
$shc.Save()
(Code originally taken from this question asked by me earlier)
Edit1:
It isn't just the case with my .py script. It's the same when opening even notepad too! And the script indeed runs fast when I boot up my PC but after some time (2-3min) it causes the delay in opening again. I Just can't figure it out why...
I don't know why it runs fast at the first 1-2 min and then slows down
(Also, running the files manually is quick. It's just slow with the script)
Edit 2
Hey guys, I just discovered that it's just the case with my computer. It's working fine on my dad's PC with pentium processor 🥲 but I still appreciate any fix for my system if possible. Thanks. May god bless you and my father. Things are really wrong with me these days...

I have an excel file on a shared drive used by 6/7 people, however only one person can edit at a time. The frustration comes when one person opens the file for editing then disappears for lunch for an hour, leaving the excel file open and un-editable for other users.
Is it possible for VBA to listen for when a station is locked, and activate a macro accordingly?
Sorry I am not posting any of my own attempts as I'm a bit of a fish out of water with this level of VBA.
Any points that may help get me started would be really useful.
You have a few options:
Kill the co-workers who do this
Have other users create a copy and save-as to then merge latter (quite hacky)
Or you try a timeout - so if the user selects nothing i 10 minutes the workbook closes. Selecting lock would be a issue with security I think and windows wouldnt let you have that kind of power.
So to timeout call a function every ten minutes to check if user has selected any other cells in the worbook.
If difference("n", lastaction , Now) > 10 Then
ThisWorkbook.Close SaveChanges:=True
End If
You can use NOW function in vba to find current date and time and the work out difference with when an action was made to find the value of 'lastaction'. To do this use:
Sub AnAction(ByVal Sh As Object, ByVal Target As Range)
lastaction = now
End Sub
Hopefully that answers your question.
Alright, so, I'm working on a script to execute some commands in an MMC Snapin, and I'm not very experienced with doing this kind of scripting, but i've made a lot of progress...the problem I am having, is if I create a new object every time the script runs, it will massively delay my overall script while the snapin and everything in it loads(which can take as long as five minutes). If it could load the snapin content once and then just take control of it as needed, and only create a new object IF there's not one open already, I'll save a massive amount of time when I run the script sometimes 100 times in a day.
The problem is, I'm not entirely certain how to achieve this. I thought, after some research, that it would be GetObject, but when I do
Dim objMMC
Set objMMC = GetObject("", "MMC20.Application")
It seems to create a new mmc window with no snapins loaded, rather than get the existing one with snapins loaded that I want.
Any advice? Am I just totally off base here, using completely the wrong command, or is there some simple change that I can make to fix this?
Edit:
Is there some weird workaround way I could achieve this, like storing an object to a temporary file so i can at least reuse it through a single session.
I'm in a weird situation where I am trying to add functionality to a powershell script and couldn't find a way to do it directly in powershell, so i'm setting up a vbscript to do one piece of it and calling the vbscript from powershell. I already had to do a lot of research to figure out how to do it in vbscript(and i'm still not sure about all of it) so i guess before i go any further, I'll try to figure out if this is even viable(in vbscript or c# or c++ or any other language someone could suggest)...
What i want to do, overall, is check if an MMC window is open that contains a DHCP snapin. If so, assign it to a variable. If not, create one.
Then it will read from a csv or txt file, and use the values to determine what node to navigate to within the snapin(DHCP>ServerName>IPv4>ScopeName>Scope Options).(I've mostly solved this part in vbscript, but don't know how to do it in C++ or C#)
Finally, I need to be able to execute a right-click menu item to "configure options", navigate the tabs of the popup that comes up, enter a value, and apply the changes/hit ok to close the popup. Worst case, If I can't do it "normally" by actually sending commands to the objects themselves, this part I can do with imitating keystrokes, but i don't want to do that if it's avoidable because it's sloppy.
Then, I basically will just need to somehow alert the powershell script that i'm "finished" so it can continue, or give an alert if there's an error.
I'm not asking anyone to walk me through all this, I just want to know if any of those steps aren't viable as i've described them, especially if I'm going to have to switch to c++ or c# to achieve the first part and therefore relearn the commands needed.
... and only create a new object IF there's not one open already ...
No, this is not possible in VBS, you need to do
Dim objMMC
Set objMMC = WScript.CreateObject("MMC20.Application")
if I create a new object every time the script runs, it will massively delay my overall script
In this case is the VBS the wrong language, you need to use C# or C++ executable.
I'm running a process that will take, optimistically, several hours, and in the worst case, probably a couple of days.
I've tried a couple of times to run it and it just never seems to complete (I should add, I didn't write the program, it's just a big dataset). I know my syntax for the command is correct as I use it all the time for smaller data and it works properly (I'll spare you the details as it is obscure for SO and I don't think that relevant to the question).
Consequently, I'd like to leave the program unattended running as a fork with &.
Now, I'm not totally sure whether the process is just grinding to a halt or is running but taking much longer than expected.
Is there any way to check the progress of the process other than ps and top + 1 (to check CPU use).
My only other thought was to get the process to output a logfile and periodically check to see if the logfile has grown in size/content.
As a sidebar, is it necessary to also use nohup with a forked command?
I would use screen for this purpose. see the man for more reference
Brief summary how to use:
screen -S some_session_name - starts a new screen session named session_name
Ctrl + a + d - detach session
screen -r some_session_name returns you to your session
Using windows cmd I have to put large programs on compilation which take large amount of time. Everytime to know whether operation is complete or not I have to check cmd again and again. I want to know whether there is way by which I can make changes to cmd such that it gives me a signal that operation has been completed by playing sound or by opening a dialog etc.
Please share if anyone has some idea
There can be many ways to achieve this
This is the easiest
While your code is compiling (ie compiling has just began) in the same cmd prompt
type " ctrl + G " and press enter this will go to the input stream of cmd and will wait there until it can be executed , ctrl +G is the BEL character which gives you a single beep when you execute it .
You can also enter multiple BEL characters to get multiple beeps upon completion of the task.
A harder way could be , to write a python script that executes the compilation command say "g++ my_prog.cpp" and upon completion plays a sound or give you a simple popup notification via a windows message box.
Include in yout batch file
msg console /time:3600 "The task has ended"
Send a message to the console and keep it open (if not closed by the user) 3600 seconds (if not indicated there is a 60 seconds timeout).
I have bash script I am running from powershell in windows that does a for loop. Every once in a while, one of the loop iteration hangs until I hit enter on the keyboard.
This doesn't happen all the time, in fact, it happens pretty rarely, but it still does.
The interesting thing is that my loop innards is basically time _command_ and so after I hit enter, it'll tell me how long the command took to run. The command actually takes way less time to execute than the loop iteration takes - because it's waiting for keyboard input for some odd reason.
It's pretty annoying to leave a script running overnight and come back in the morning to see that it didn't get very far.
Does someone knows WHY this happens and WHAT to do to get around it?
Thanks,
jbu
I have encountered the same problem several times. Now I guess I have found the reason!
If you ever press the mouse within the powershell, it might get stuck and need user to press "enter" to continue. So the get-around-way is to make sure that you didn't accidentally press your mouse within the shell window while you are already running some program...
Goto the powershell properties and unselect 'Quick Edit'/'Insert' check boxes. If these are selected, the console pauses output and resumes only when an Enter key is pressed ( You can identify this by monitoring the console title bar- it will switch from "Administrator:Windows PowerShell" to "Select Administrator:Windows Powershell"
Until you post the script, there's little we can do to help.
However, in general, one of your commands probably returns a null once in a while as input to stdin of another command which, upon seeing null looks to the terminal as stdin. Or something along those lines.
