Original Pull Request: https://github.com/microsoft/terminal/pull/17436

State: closed
Merged: Yes

More descriptive warnings are triggered when custom pixel shader compilation fails.

If D3DCompileFromFile fails and the compiler generates an error message- the message is converted to a wstring and is sent as a parameter when calling p.warningCallback.
Changes were made to resources.resw and TermControl.cpp to accommodate this.

Validation Steps Performed

I tested the following errors that may be encountered while developing a custom pixel shader:

  1. Compile time errors
  2. File not found error
  3. Path not found error
  4. Access denied error

Fixes #17435

TAEF tests passed:
Summary: Total=294, Passed=294, Failed=0, Blocked=0, Not Run=0, Skipped=0
