//
|
|
// VB SYNOPSIS
|
|
//
|
|
// None, this function just isn't going to work with Vb.
|
|
//
|
|
// DELPHI SYNOPSIS
|
|
//
|
|
// None, not a good fit for Delphi.
|
|
//
|
|
// ARGUMENTS
|
|
//
|
|
// hDlg : This argument is a window handle. If the next parameter,
|
|
// control_id, is set to -1, it means this is the handle of
|
|
// the window that will have some new text written to it.
|
|
// If control_id is some other value, it means this is the
|
|
// handle of a dialog box, and control_id refers to an edit
|
|
// control within the dialog box. That edit control is the
|
|
// destination for the text output.
|
|
//
|
|
// control_id : The id of the multiline edit control in a dialog box. If
|
|
// set to -1, it means the edit control is not in a dialog box,
|
|
// and the hDlg parameter is the handle of the edit control.
|
|
//
|
|
// fmt : The format parameter to be used in wsprintf.
|
|
//
|
|
// ... : Any additional arguments that are going to be used by
|
|
// vsprintf().
|
|
//
|
|
// DESCRIPTION
|
|
//
|
|
// This little function lets you use a printf() style command to print
|
|
// data to a multiline edit control. The internal buffer is only 128
|
|
// bytes, so please be careful.
|
|
//
|
|
// RETURNS
|
|
//
|
|
// Nothing.
