Problems with virtual desktops #3

Open rahenry opened 4 years ago

rahenry commented 4 years ago

I like to run Median on a wine virtual desktop, otherwise I get occasional crashes, and a few seconds of blackscreen when switching workspaces. Unfortunately I can only get D2Stats.exe to work if it's in the same virtual desktop as Median (run with sigma-loader.exe). This is a problem because once D2Stats is "behind" Median, I can't access it anymore. Ideally I would like D2Stats to work in a separate virtual desktop (which requires a separate wineprefix), or without a virtual desktop (through program-specific settings in winecfg), but it won't work in these situations. It doesn't crash, but it can't detect stats or have any effect on Median/D2. I find that it works fine if both D2Stats and Median aren't using a virtual desktop, or if they're in the same virtual desktop, but not in any other case.

More info: I'm running wine 5.0-rc4. I've tried both 64 and 32-bit prefixes, same results.

Not sure if you can help with this, but perhaps you have some experience with it.

Maybe you need some software that minimizes and maximizes diablo?

Hey Syndrome,

I wanted to re-write your code in a language I was more familiar with, like Python. However, reading over your code, fundamentally I do not understand why it works and why it fails when called directly with wine.

If this concept is plain to you, I would very much appreciate to hear your thoughts. My endgame, I would like to accomplish what rahenry has asked. Utilize wine's virtual desktop while running D2Stats for injection for my own use and others if I get it working.

Thanks

Update: I think I see. Rather then leave wine to run game.exe, you setup the process with the dll directly in your code. If I do the same thing but point it to d2stats, I would think that it would work. Will link code if I get it working. Ty for code you've already provided.

Diablo uses Windows Api to deny any access to its process. I use SetSecurityInfo() api call to disable it.

SetSecurityInfo() requires process handle with full access rights which i receive from CreateProcess() function.

My loader literally consists of 3 api calls:

  1. CreateProcess()
  2. WaitForInputIdle()
  3. SetSecurityInfo()

Just repeat them in Python and your loader is done.

Very cool man, thanks for the knowledge drop.
