如题。
实际上我在做一个倒计时软件,用来计时游戏里人物的增益BUFF状态。我想要的效果是我游戏时倒计时软件(快捷键F1)还能最前,但没有焦点。因为我要操作游戏人物。当我按F1时,倒计时软件还能响应他自己的功能。我是个编程小白,最近才学C#,所以最好有示例代码。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;namespace sdg
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
label1.Text = "按F1";
}
private void button1_Click(object sender, EventArgs e)
{
label2.Text = "快捷键生效!";
}
private void Form1_KeyDown(object sender, KeyEventArgs e)//是针对窗口的快捷键不是Button1的
{
if (e.KeyCode == Keys.F1)
{
button1_Click(sender, e);
}
}
}
}
這個程序不好使,但效果就是這樣,希望大家幫幫忙。

private void Form1_KeyDown(object sender, KeyEventArgs e)不就是註冊的全局快捷鍵嘛?

}刚好前段时间做了个程序,就是关于全局快捷键的。楼主加上这些东西,formload的时候register下,formclose的时候unregister下,就ok了。
2.C#调用非托管代码
