[英]KeyDown Issue c#
I'm currently trying to make a keydown register.我目前正在尝试制作一个 keydown 寄存器。 Basicly just to see which keys i use the most.
基本上只是为了看看我最常使用哪些键。 The problem is that only want it to detect the F1-F12 buttons.
问题是只希望它检测 F1-F12 按钮。 Another issue is don't really know how to attack it since it must be a globalevent.
另一个问题是不知道如何攻击它,因为它必须是一个全局事件。
if (e.KeyCode.ToString() == "F1")
{
MessageBox.Show("F1 pressed");
}
Is what I've been trying so far, I do have to focus the application for it to work tho.到目前为止,这是我一直在尝试的,我必须专注于应用程序才能正常工作。
I DO NOT want the user to register the hotkeys on their own.我不希望用户自己注册热键。 I want them set, that's what differs this from Set global hotkeys using C#
我想设置它们,这与使用 C# 设置全局热键的不同之处
When I need to do this in C#, I just import User32.dll, and utilize the GetASyncKeyState function as follows:当我需要在 C# 中执行此操作时,我只需导入 User32.dll,并使用 GetASyncKeyState 函数如下:
[DllImport("User32.dll")]
private static extern short GetAsyncKeyState(System.Windows.Forms.Keys vKey);
private void globalKeyThread()
{
int state;
System.Windows.Forms.Keys keyToCheck = Keys.Space;
while (true)
{
state = Convert.ToInt32(GetAsyncKeyState(keyToCheck));
if (state == -32767)
{
// Handle what happens when key is pressed.
}
Thread.Sleep(10);
}
}
private void globalKeyThread()
{
System.Windows.Forms.Keys keyToCheck = Keys.F12;
while (true)
{
state = Convert.ToInt32(GetAsyncKeyState(keyToCheck));
if (state == -32767)
{
// Handle what happens when key is pressed.
timer1.Start();
}
Thread.Sleep(10);
}
}
The issue right here might be the Int32 response perhaps?这里的问题可能是 Int32 响应? Since the application is not really understanding what i'm trying to do.
由于应用程序并没有真正理解我想要做什么。
using System.Runtime.InteropServices;
Import User32.dll:导入 User32.dll:
[DllImport("User32.dll")]
private static extern short GetAsyncKeyState(System.Windows.Forms.Keys vKey);
Next create function will check that key is pressed:下一个创建函数将检查是否按下了键:
private bool globalKeyThread(Keys key)
{
int state;
state = Convert.ToInt32(GetAsyncKeyState(key));
if (state == -32767)
{
return true;
}
return false;
}
Now function for timer is only for F1:现在计时器功能仅适用于 F1:
private void timer1_Tick(object sender, EventArgs e)
{
timer1.Enabled = false;
if (globalKeyThread(Keys.F1))
{
MessageBox.Show("F1 press");
}
timer1.Enabled = true;
}
