EM_SETSEL
An application sends an EM_SETSEL message to select a range of characters in
an edit control.
EM_SETSEL
wParam = (WPARAM) (INT) nStart; // starting position
lParam = (LPARAM) (INT) nEnd; // ending position
Parameters
nStart
Value of wParam. Specifies the starting character position of the selection.
nEnd
Specifies the ending character position of the selection.
Return Values
This message does not return a value.
Remarks
In a rich edit control, if the selection is not entirely contained in the
first 64K, use the message EM_EXSETSEL.
If the nStart parameter is 0 and the nEnd parameter is  1, all the text in the edit control is selected. If nStart is 1, any current selection is removed. The caret is placed at the end of the
selection indicated by the greater of the two values nEnd and nStart.
In previous versions of Windows, the wParam parameter is a flag that is set to FALSE to scroll the caret into view or set
to TRUE to omit the scrolling. A Win32-based application should use the
EM_SCROLLCARET message to scroll the caret into view.
In earlier versions of Windows, the starting and ending positions of the
selection are indicated by the low- and high-order words, respectively, of the lParam parameter.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
