IOException thrown when calling AdjustWindowSize

[rpwjanzen]

Calling ConsoleManager.AdjustWindowSize() in a tight loop while resizing the window with the mouse can cause a System.IO.IOException to be thrown.

Exception Details

System.IO.IOException: The parameter is incorrect.
   at System.ConsolePal.SetCursorPosition(Int32 left, Int32 top)
   at ConsoleGUI.Api.StandardConsole.set_Size(Size value)
   at ConsoleGUI.ConsoleManager.Resize(Size& size)
   at ConsoleGUI.ConsoleManager.AdjustWindowSize()

Might want to add a SafeConsole.SetCursorPosition method.

I wasn't able to reproduce it on my side. What OS/terminal are you using?

But nevertheless, adding a SafeConsole.SetCursorPosition seems like a good idea regardless. Those console APIs are bit wonky.

Should be fixed in v1.2.1 by 1863c5c6cd51304aa604d3a021686d945d566b37 Please let me know if you can reproduce this issue with the new version of the package.

[rpwjanzen]

I am using the "Command Prompt" (cmd.exe) terminal on Windows 10 version 1903 (Build 18362.1139).

Below is an example of code that will reproduce the issue.

    // while running, resize the window to be really small
    class Program
    {
        static void Main(string[] args)
        {
            ConsoleManager.Setup();
            ConsoleManager.Content = new TextBlock
            {
                Text = "Text Block"
            };

            while (true)
            {
                ConsoleManager.AdjustWindowSize();
                System.Threading.Thread.Yield();
            }
        }
    }

I think I was able to reproduce it on my end as well. Can you please confirm that it only happens when the window is resized to a point where it's completely collapsed? Or does it happen also where there is some drawind space visible?

Should be fixed in v1.2.2 by 42fd2f84a4ea86912c34f2813593a41fde9461c7

[rpwjanzen]

This issue does occur when there is some drawing space visible. It appears to happen when the Console.SetCursorPosition(_, 0) is called. v1.2.2 appears to have fixed the issue.

[TomaszRewak]

Interesting, on my side it was only happening when the window was 0px tall. But v1.2.2 should take care of that and all other edge cases.

I'm closing the ticket.

Thanks for reporting and the help in investigating :)
