I have suspicions that ReadAllText works unacceptably bad, the fact is that forms appear with a change in transparency from zero to one, and that's when a form with a TextBox is called (without background images), and a very 40kb txt file is loaded into TextBox noticeable changes in the rate of change of transparency

this->Opacity = i + 0.1;

Roughly speaking - it slows down! Do not think my computer is not weak for this operation.

    File operations should always be done in a background thread. If the user fell asleep screw, he should not see hung UI your program. Disk read performance is not guaranteed to anyone. - VladD
