求用快捷键实现最大最小化窗体到托盘.五十分.不够再加.顶者有分!
求用快捷键实现最大最小化窗体到托盘.
网上有直接加的,那种方式可以实现.可是利用快捷键怎么也不实现不了.现在我写了一部分.
只是实现了按了F12后最小化了,可是再按时就出错了.
请高手指教.   为了不影响大家的思路,先不贴我写的代码.

------解决方案--------------------
这个问题其实分成两个:
1.注册/删除热键问题
2.最大最小化窗体到托盘.

第2个问题不说了,太简单了,我觉得你的问题可能是注册热键.帖一段我写的代码给你看看:

/// <summary>
/// 自定义控制键枚举
/// </summary>
[Flags()]
public enum KeyModifiers
{
None = 11,
Alt = 12,
Control = 13,
Shift = 14,
Windows = 15
}

//为窗体注册热键
[DllImport( "user32.dll ", SetLastError=true)]
public static extern bool RegisterHotKey(int hWnd,int id,KeyModifiers fsModifiers,Keys vk);

//为窗体注销热键
[DllImport( "user32.dll ", SetLastError=true)]
public static extern bool UnregisterHotKey(int hWnd,int id);


public Keys m_hotkey;
public bool m_ctrlhotkey, m_shifthotkey, m_althotkey, m_winhotkey;

public HotKeys()
{
}

public HotKeys(Keys c, bool bCtrl, bool bShift, bool bAlt, bool bWindows)
{
this.m_hotkey = c;
this.m_althotkey = bAlt;
this.m_ctrlhotkey = bCtrl;
this.m_shifthotkey = bShift;
this.m_winhotkey = bWindows;
}

------解决方案--------------------
我给你个方法
System.Timers.Timer tim;
[System.Runtime.InteropServices.DllImport( "user32.dll ", SetLastError=true)]
public static extern short GetAsyncKeyState(int id);
private void Form1_Load(object sender, System.EventArgs e)
{
tim=new System.Timers.Timer(1);
tim.Elapsed+=new System.Timers.ElapsedEventHandler(tim_Elapsed);
tim.Start();
}
private void tim_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
short s=GetAsyncKeyState(123);//123 就是F12
if(s <0)
{
this.Visible=false;//这里写你要干什么,要是还有问题,字条我
}
}
------解决方案--------------------
单键还不是一样？
if(s <0)
{
//this.Visible=false;//这里写你要干什么,要是还有问题,字条我
if(iStat==0)
{
隐藏;
iStat=1;
}
else
{
打开;
iStat=0;
}
}

F12不行.其它都行.不知道为什么?

======================================

2种可能,你的f12坏掉了,你的F12被注册过了,关掉所有程序,跑一次.注意关掉VS
------解决方案--------------------
光一个F12不能注册为全局HotKey
如下是Ctrl+F12

public const uint MOD_ALT = 1;
public const uint MOD_CONTROL = 2;
public const uint MOD_SHIFT = 4;
public const uint MOD_WIN = 8;
private const int F12IDENT = 0x0010;
[DllImport( "user32.dll ")]
public static extern bool RegisterHotKey(IntPtr hWnd, int id,
uint fsModifiers, int vk);

[DllImport( "user32.dll ")]
public static extern bool UnregisterHotKey(IntPtr hWnd, int id);

private void Form1_Load(object sender, EventArgs e)
{
RegisterHotKey(Handle, F12IDENT, MOD_CONTROL, (int)Keys.F12);
}

private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
UnregisterHotKey(Handle, F12IDENT);
}
public const int WM_HOTKEY = 0x0312;
protected override void WndProc(ref Message m)
