DirectX Error on Workspace Switch – D2DERR_WRONG_RESOURCE_DOMAIN from OnRender, despite SharpDX best practices

Create SimpleFont public property to be used for TextFormat. TextFormat can be declared and assigned once, then re-used. TextLayout not so much. I would recommend using() statement. While you do not need a TextLayout to just render a DrawText. Easier to grab the height and length of string from Metrics. public class HTBlank : Indicator { private bool isConfigSet = false; private string myString = "Test String"; private SharpDX.DirectWrite.TextFormat myTextFormat; protected o…

If your possibly looking for a textbox, you can interact with,

OnBarUpdate runs ahead on its own thread, so myTextBox doesn’t exist yet for the first ~2500 bars. OnBarUpdate also shouldn’t touch a WPF control directly, since it’s on the wrong thread. The cleaner way is to bind the TextBox to a property. OnBarUpdate only reads or sets the property and never touches the control, so it doesn’t matter when the box gets built. It works both ways: typing cha…
