Question: installation path
TheAsmitKid opened this issue · 18 comments
Hey.. I am a beginner taking about win32api via c++.. so I'm sorry if this is a stupid question..
I'm developing a little app for myself and I was wondering if it's alright if I unzip the release to somewhere else except C:\IddSampleDriver\ like `C:\MyProject\utils'
(If i need to recompile it.. i can't install wdk or visual studio right now so can I make changes directly to the .inf file if required via notepad++ or vscode and then generate a catalog and certificate for it?)
another sorry if my english is bad...
The string C:\IddSampleDriver\ is directly written in Driver.cpp, which is compiled into the main binary file of this driver (IddSampleDriver.dll). This means you need to recompile it with wdk and visual studio to change the path.
Of course, the directory could essentially be anywhere. I fixed the string just because I wanted to simplify my work.
Do you have any problem with the fixed C:\IddSampleDriver\?
backstory: Actually I am working for a desktop utility project "Boweci" and I've been searching for a way to generate virtual displays, i really liked Microsoft's concept of indirect display and i found this repo upon searching for precompiled ones but when the user is installing my app, it would be inconvenient to have it install in different folder.. so I was wondering if I can just make it a part of my installer
Question: could you help me somehow? Like manufacturers' drivers does not have to be installed that way, or have the option.txt in C:\Windows\System32\
Request: And if compilation doesn't take a long period of time.. could you please compile it for me for path C:\Boweci\ i know i shouldn't ask u but it'd make things easier for me if u could ^__^
Nevertheless.. thank you for making this project, it's been a knowledgeable journey for me ( ╹▽╹ )
OK, I'll work on adding some mechanism for changing installation directory.
Thank you so much! After that i could easily integrate it with my app, I think i might complete it near my 11 November goal! Really thankyou♡
Shall I close the issue?
I think I'll add an environment variable to override the default location.
Then I close this issue.
Okay
https://github.com/ge9/IddSampleDriver/releases/tag/0.0.1.4
I added the release.
Does this work for you?
Looks good, i just gave my exam so I'll check later
Also, one question
Can I use devcon to restart the driver instead of rebooting?
does not work, i even restarted my pc, it still didn't work, so i reinstalled the prev version and that works just like it did,
this new one just does not work, i have tried setting IDD_SAMPLE_DRIVER_CONFIG to C:\Boweci\ (installation path) and C:\Boweci\option.txt
i then reinstalled the new one in the dir shown in pic, doesnt work
IDD_SAMPLE_DRIVER_CONFIG should be file path to the config file, C:\Boweci\option.txt in your case.
In my testing, the system that manages device drivers seems to load environment variables only when Windows starts. So normal driver reloading won't work (though there might be some way that I'm not aware of).
IDD_SAMPLE_DRIVER_CONFIG should be file path to the config file, C:\Boweci\option.txt in your case.
still a no

not working even after a restart
APPARENTLY i deleted C:\Windows\System32\Drivers\UMDF\iddsampledriver.dll and copied the one in the installation folder then restarted, and it works now
Now do I have to do it every time? I mean it's 2 more steps and it'd take just one line in my code to copy it.. but is it necessary? playing with system files in someone's else's computer...
Ohkay it might be because the driver was not installed properly
I reedited the folder name and restarted the driver then it showed the same error
But I edited the env var end restarted the driver didn't work(expected)
Restarted my pc and it works
So sorry to bother you
And thank you very much!
can u give me access to the repo? i have a couple ideas in mind for improvement
