我想要发生的是,当单击一个文本框时,会显示一个弹出式键盘,并且我在键盘上输入的任何内容都将被放入文本框中,但是没有任何反应,但是当我使用记事本时,它可以工作。我怎样才能解决这个问题?
这是我的主要表单代码:
private void textBox1_MouseClick(object sender, MouseEventArgs e)
{
Form1 frm1 = new Form1();
frm1.ShowDialog();
}
这是我的弹出键盘代码
public partial class Form1 : Form
{
const int WS_EX_NOACTIVATE = 0x08000000;
//this line of code fixed the issue
[DllImport("user32.dll", EntryPoint = "GetDesktopWindow")]
public static extern IntPtr GetDesktopWindow();
public Form1()
{
InitializeComponent();
}
protected override CreateParams CreateParams
{
get
{
CreateParams param = base.CreateParams;
param.ExStyle |= WS_EX_NOACTIVATE;
//This line of code fix the issues
param.Style = 0x40000000 | 0x4000000;
param.Parent = GetDesktopWindow();
return param;
}
}
private void button1_Click(object sender, EventArgs e)
{
SendKeys.Send("1");
}
private void button3_Click(object sender, EventArgs e)
{
SendKeys.Send("2");
}
private void button4_Click(object sender, EventArgs e)
{
SendKeys.Send("3");
}
private void button2_Click(object sender, EventArgs e)
{
}
}
