EM_GETHANDLE Overview  Group

An application sends an EM_GETHANDLE message to retrieve a handle of the memory currently allocated for a multiline edit controlís text.


wParam = 0; // not used; must be zero 

lParam = 0; // not used; must be zero 



This message has no parameters.

Return Values

The return value is a memory handle identifying the buffer that holds the content of the edit control. If an error occurs, such as sending the message to a single-line edit control, the return value is zero.


In a 16-bit Windows-based application, the handle is a local memory handle and can be used only by functions that take a local memory handle as a parameter. The application can send this message to a multiline edit control in a dialog box only if it created the dialog box with the DS_LOCALEDIT style flag set. If the DS_LOCALEDIT style is not set, the return value is still nonzero, but the return value will not be meaningful.
