what language would be useful to make a program that looks in a directory and saves the amount of files inside of it as a variable then have it check if the variable does not equal what it was originally when it counted then run a script. since i have a folder that adds a new file to the directory every time something is changed i want a script to run that just runs an exe.
I have no idea on where to get started, if i should make a vb.net app thats a timer that runs every so often and does this for me. please help!!!
Thank you so much. Sorry I included no code I'm not expecting code in return i just need ideas on how i would plan this or go about doing it.
You can look into this class for watching updates into a directory and taking action against various types of updates

Im developing a system using vb2022 its almost done but today the changes I made doesn't reflect on run time.
For example I added a button but when I run the program the button will not show.
Same as the code, i can write code but it doesnt reflect on run time
Plus im trying to change the startup form into form 2 (initial is form 1) but it doesn't reflect.
What should I do? I didn't change anything I just opened the file and write code. But suddenly this happened.
Most likely your build is failing and VS is automatically running the old output. When that happens, VS will prompt you whether to run the old output or not by default, but many people tell VS not to prompt them again without actually reading the dialogue. Use the Build menu to build your project/solution and pay attention to the Output and Error List windows to see whether it failed or not.
It may be that the compilation is succeeding but VS simply can't overwrite the output files because they are locked, which does happen sometimes. In that case, just delete the entire obj and bin folders from your project folder. You may need to close VS to do so. The next time you build, new output will be created and run.
If this happens regularly then you should probably repair VS and, if it continues after that, reinstall.
im working on my first big program. I will try to explain short how the important part of the program works, and then try to explain what my problem is.
My program is used by few people, they drive around the Europe and repair our machines. After the work, they start my program, and write a report. Until now the program was generating at the end 3 Files. (PDF file generated by printform, text file which contained the same information's again and the last file that was an Excel file, that one contained Data that was written inside the Datagridview.
These workers, used Email to send all 3 files separated. As you imagine, sometimes that can end bad, cause after work they are tired and sometimes they send the wrong files. So I made a upgrade, which gives the user a possibility to send the files directly from the Program, being sure everything is fine. In background I created a directory where 2 of 3 files always get saved. The problem is, while using printform, there opens a window where the user can select the path. And here start the troubles, some of the workers select different a different path, but then my program wont find the files again(its very important that are 3 files are together). I searched for something that would look like
dim printformpath as string = printform.getpath
is there something that works that way? I was searching but I didn't found anything helpful.
Thank you for understanding & help
Thanks, I added the path to the printFileName property and changed printform settings from Print to preview to print to file :)
Have a nice day
My application updates(running a vba script) an excel shared workbook, and since it is shared, there shouldn't be problems when someone else is using the same file at the same time. But for some reason, sometimes it simply freezes, without any error message, just freezes.
Is there a way to programatically make the application stops/closes automatically when frozen or after some minutes(In normal conditions, this updating process shouldn't take more than 1 minute)?
And, if possible, re-launch the app again automatically after some minutes for at least 5 attempts?
This way would ensure process completes succesfully.
I have had to do this same thing before but because I had an application that would look for updates to it's self on the network and then update it locally. Problem is, you cannot update the exe that is running.
What I did to get around it is to create another program that would wait a second, update the exe, then run the exe again.
Because I did this with a few different apps, I made my "Updater" generic so I could send some command line parameters and it would use those to copy and run.
If you want to try something else, you might be able to accomplish this same thing by creating a BAT file and running it. I'm not real good on BAT files so I can't help you there. But, it is another way to handle it.
I have a small VB .Net application that, among other things, attempts to substitute system wide typed text by the user(hotstrings concept). To achieve that, I have deployed 'ahk2exe' and 'AutoHotkeySC.bin' with my application and did the following:
When a user assignes a new 'hotstring':
Kill 'hotstring' exe script file if running
Append new hotstring to the script file (if non exist then create a new one)
Convert edited/new script file to exe (using ahk2exe)
Run the newly converted script exe
(somewhere there I also check if the hotstring has been already assigned)
However, I am not totally satisfied with this method for the following two main reasons:
The extra resources deployed with the application.
Lag: The time it takes for the system to kill the process and then restart it takes a minimum of 5 seconds on my fast computer and more on other computers. That amount of time is much more than the time it takes the user to assign the hotstring, minimize/close the window and then test his/her new hotstring. When the user does so initially with no success they will think the process failed. So this method is not very good for user experience.
So, I am looking for a different method or implementation. May be using keyboard hooks? Or maybe adding a .dll library that achieves the same. Are there any resources you know about that might help (free or commercial)? What is the best way to achieve my desired goal?
Many thanks for your help.
Implementing what Autohotkey does would be a pretty non trivial task.
But I'm pretty sure that AHK supports an "autoreload" option for scripts
googling "autohotkey auto reload" turned up several pages discussing that very concept. IF that worked, all you'd have to do is update the script file and that's it, AHK should automatically reload the script.
I need to start an external process (which is around 300MB large on its own) several times using System.Diagnostics.Process.
The only problem is: once the first instance starts, it generates temporary data in its base folder (where the application is located), so I can't just start another instance - it would corrupt the data of the first one and mess up everything.
I thought about temporarily copying the whole application folder programmatically, so that each instance has its own, but that doesn't feel right.
Could anybody help me out? Thanks in advance!
Try starting each copy in a different directory.
If the third-party app ignores the current directory, you could make a symlink to it in a different folder. I'm not necessarily recommending that, though.
Pass an argument to your external process that specifies the temp folder to use.
