TMemo / TRichEdit有更多内存

Question

Is there any way to assign more memory for a Memo or RichEdit (if working with big files)

thanks

Answer 1

Allocate memory with LocalAlloc and then give it to the edit control with the em_SetHandle message. You can handle the en_ErrSpace notification if the edit control requires more space. MSDN describes the process in the "About Edit Controls" article . It doesn't work on rich-edit controls, though; they don't store their data in a contiguous buffer like edit controls do.

Answer 2

Rather than load the whole file, wouldn't it be better to use the control as a 'window' to the data? Just load your data in chunks, loading more (and getting rid of some) as the user scrolls up or down.

Answer 3

我建议切换到另一个编辑控件，例如SynEdit （它可以在几毫秒内加载80 mb的文本文件）。
