|---|---|
Any editable control, other than a RichTextEdit |
|
A RichTextEdit control or a DataWindow whose object has the RichTextEdit presentation style |
Selects text in an editable control. You specify where the selection begins and how many characters to select.
DataWindow, EditMask, MultiLineEdit, SingleLineEdit, DropDownListBox, and DropDownPictureListBox controls
editname.SelectText ( start, length )
Argument |
Description |
|---|---|
editname |
The name of the DataWindow, EditMask, MultiLineEdit, SingleLineEdit, DropDownListBox, or DropDownPictureListBox control in which you want to select text. |
start |
A long specifying the position at which you want to start the selection. |
length |
A long specifying the number of characters you want to select. If length is 0, no text is selected but PocketBuilder moves the insertion point to the location specified in start. |
Long. Returns the number of characters selected. If an error occurs, SelectText returns -1. If any argument’s value is null, SelectText returns null.
If the control does not have the focus when you call SelectText, then the text is not highlighted until the control has focus. To set focus on the control so that the selected text is highlighted, call the SetFocus function.
How much to select
When you want to select all the text of a line edit or select
the contents from a specified position to the end of the edit, use
the Len function to obtain the length of the
control’s text.
To select text in a DataWindow with the RichTextEdit presentation style, use Syntax 2.
This statement sets the insertion point at the end of the text in the SingleLineEdit sle_name:
sle_name.SelectText(Len(sle_name.Text), 0)
This statement selects the entire contents of the SingleLineEdit sle_name:
sle_name.SelectText(1, Len(sle_name.Text))
The rest of these examples assume the MultiLineEdit mle_EmpAddress contains Boston
Street.
The following statement selects the string ost and
returns 3:
mle_EmpAddress.SelectText(2, 3)
The next statement selects the string oston
Street and returns 12:
mle_EmpAddress.SelectText(2, &
Len(mle_EmpAddress.Text))
These statements select the string Bos,
returns 3, and sets the focus to mle_EmpAddress so
that Bos is highlighted:
mle_EmpAddress.SelectText(1, 3)
mle_EmpAddress.SetFocus()
Selects text beginning and ending at a line and character position in a RichTextEdit control.
RichTextEdit and DataWindow controls
rtename.SelectText ( fromline, fromchar, toline, tochar { band } )
Long. Returns the number of characters selected. If an error occurs it returns -1. If any argument’s value is null, SelectText returns null.
