SendKeys.Send(“{HOME}”)，vb.net
我在 MaskedTextBox 中使用 SendKeys.Send("{HOME}") 在文本为空时将光标移至文本框的开头。
当我尝试关闭项目时，如果应用程序没有焦点，它就会冻结。
在调用 SendKeys 之前，如何将此应用程序置于焦点位置？
Public Class Form1
Private Sub MaskedTextBox1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles MaskedTextBox1.GotFocus
Try
SendKeys.Send("{HOME}")
Catch ex As InvalidOperationException
' Do nothing
End Try
End Sub
End Class
之后，它应该将焦点集中到前一个应用程序并关闭。
I am using SendKeys.Send("{HOME}") in a MaskedTextBox to bring the cursor to the beginning of the textbox when the text is empty.
When I try to close the project the application freezes if it doesn't have focus.
How do I put this application in focus before I call SendKeys?
Public Class Form1
Private Sub MaskedTextBox1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles MaskedTextBox1.GotFocus
Try
SendKeys.Send("{HOME}")
Catch ex As InvalidOperationException
' Do nothing
End Try
End Sub
End Class
After that, it should give focus to the previous application and close.

我正在使用 Visual Basic 登录，但它不在运行时运行。突出显示 SENDKEYS 为违规者。这是我的代码
Private Sub cmdOK_Click()
'检查密码是否正确
如果 txtPassword = "密码" 那么
'将代码放在这里以传递
'调用子程序成功
'设置全局变量是最简单的
登录成功 = True
我隐藏
别的
MsgBox "密码无效，请重试！", , "登录"
txt密码.SetFocus
发送键“{HOME}+{END}”
结束如果
结束子
I am using visual basic login and it it is not running at run-time. Highlights SENDKEYS as the offender. Here is my code
Private Sub cmdOK_Click()
'check for correct password
If txtPassword = "password" Then
'place code to here to pass the
'success to the calling sub
'setting a global var is the easiest
LoginSucceeded = True
Me.Hide
Else
MsgBox "Invalid Password, try again!", , "Login"
txtPassword.SetFocus
SendKeys "{HOME}+{END}"
End If
End Sub
{HOME} 就像按 home 键，这不会带来焦点。
获得焦点的最佳方法是调用文本控件上的 focus 方法。就像文本框.focus();
请包含您的页面代码，或页面内容的示例。
MaskedTextBox1.选择(0,0)
{HOME} is like hitting the home key, this will not bring focus.
best thing to do to bring focus is to call the focus method on the text control. like textbox.focus();
Please include your page code, or an example of what is on the page.
MaskedTextBox1.Select(0,0)
在 SendKeys 之前给文本框一个焦点
Give the textbox a focus before the SendKeys
