在google上面搜到下面的微软的地址，可是看不了

{

Control self = sender as Control;

SendMessage(self.Handle, EM.SETWORDBREAKPROCEX, 0, new WordBreakProc(MyWordBreak));

}

VB

Sub TextBox1_CreateHandle(ByVal sender As Object, ByVal e As EventArgs) Handles TextBox1.CreateHandle

Dim self As Control

self = CType(sender, Control)

SendMessage(self.Handle,EM.SETWORDBREAKPROCEX,0,AddressOf MyWordBreak)

End Sub

のようにしてるとダメです。このような場合は GCHandle を利用して、

C#

private delegate int WordBreakProc(IntPtr pchText, int cchText, byte bCharset, int code);

private void TextBox1_HandleCreated(object sender, EventArgs e)

{

Control self = sender as Control;

WordBreakProc proc = new WordBreakProc(MyWordBreak);

// とりあえず Tag プロパティに保存する

self.Tag = GCHandle.Alloc(proc);

// callback を登録

SendMessage(self.Handle, EM.SETWORDBREAKPROCEX, 0, proc);
