还有这句不能理解..是干什么用的???看不到效果

这个意思也不懂

[此贴子已经被作者于2006-3-14 17:21:34编辑过]

有人回答吗

private void cboOccupations_KeyDown(object sender, KeyEventArgs e)
{
int index = 0;
ComboBox cbo = (ComboBox)sender;
if (e.KeyCode == Keys.Enter)
index = cbo.FindStringExact(cbo.Text);
if (index < 0)
cbo.SelectedIndex = index;
e.Handled = true;

}
查找到文本对应的索引后, 没有进一步处理.

有人能回答吗

这句。自己到自己的文本里找？？index = cbo.FindStringExact(cbo.Text);

这句什么意思 e.Handled = true;

public override void Dispose()
{
SaveOccupation();
base.Dispose();
if (components != null)
components.Dispose();
这个意思也不懂

e.Handled // 获取或设置一个值，该值指示是否处理过此事件。


public override void Dispose() // 释放资源
{
SaveOccupation();
base.Dispose();
if (components != null)
components.Dispose();
}
