BUG: Text Truncated in Edit Control

 * }

Q111341

-

The information in this article applies to:


 * Microsoft Win32 Software Development Kit (SDK), version 3.1

-

SYMPTOMS
Copying and pasting a very large block of text in a multiline edit control may result in part of the text being truncated or some of the text being misaligned. This problem is more likely to happen when using a large size font instead of the default font for the edit control.

STATUS
Microsoft has confirmed this to be a bug in Windows version 3.1.

MORE INFORMATION
When pasting the text, the default window procedure for the edit control calls the ExtTextOut function to display the text. The last parameter to ExtTextOut is int FAR* lpDx, which specifies the spacing between character cells. For a very long string, there may not be enough stack space for the entire lpDx array, and therefore the string is truncated. When this happens, if you are running the debugging version of Windows, you will see the message "not enough stack space for DX array. String truncated."
