Help debugging some problem

[hammerpiano]

Hi,
I am trying to make a plugin for Elite Dangerous. The plugin is an expedition assistant. It loads a csv file, with planets names, and tells what planets to scan and in which system. It has 5 commands:
1. Init - read csv
2. Start - say first system
3. Next system - iterate through systems
4. Abort - aborts the expedition
5. repeat planets - repeats which planets to scan

For some reason, voiceattack crashes after running "Next System" command. VoiceAttack generated one log file, and then stopped generating files. When it crashes, I don't see any error messages, logs or whatever, it just closes.

Here is the log file:

I tried surronding the contents of the function VA_Invoke1, but VoiceAttack still crashes.

There is a test profile I use, and the csv file. In the "init" command, set the variable path to the path of the csv.
I run the following order of commands:
1. init
2. start
3. next system (run until it finishes)

Is this a bug in my code that I can't find?

The exception text indicates the issue is within unmanaged code.

If I were you I'd use the System.Windows.Forms.Clipboard class, instead of using P/Invoke to call unmanaged methods.

When I removed the copy to clipboard part, the crashing stopped, so thats nice.
When I used the Clipboard class, I had crashes stating that I need to use STA thread. So now I create one, to do the copying, and it works without problems.
I pushed the fix to the repository.

Thanks for the help!
