SendKeys (args[]) method Detailed (VB):
vb.net using SendKeys remote control:
Everyone in the VB6 have used SendKeys, the screen by sending the keyboard events indirectly control the external program, is a remote control of the said.
I found in the vb7 that this can not be used, and then nothing, and then once in the review of MSDN when unexpectedly saw this, is to try a bit, unexpectedly a facelift, or as good.
Mainly found in the System.WinForms clan SendKeys use method with VB6
Key: General character keys as follows enter "a" "B" "C" ......... z ", if you want to press more than two consecutive use of" AB "if you press AB at the same time use parentheses such as" (AB) "
If it is a function key, it is placed in curly braces as "{F4}" another: With + for SHIFT, ^ for CTRL, and% for Alt
If "+a" means press shift and press a
Here is an example：
Dim sdstr As System.winforms.sendkeys
Sdstr.send ("%{f4}") Send Alt+f4
The following code shifts the focus to the next control after pressing button2 so that the button presses and does not press the focus.
Copy Code code as follows:
Protected Sub Button2_Click (ByVal sender As Object, ByVal E
As System.EventArgs)
Dim sdstr As System.winforms.sendkeys
Sdstr.send ("{tab}")
End Sub
Using sendwait below, the same method is used, but executing this procedure waits until the key that is sent completes, and then executes the following code.
Copy Code code as follows:
Protected Sub Button2_Click (ByVal sender As Object, ByVal E
As System.EventArgs)
Dim sdstr As System.winforms.sendkeys
' Sdstr.send (' {tab} ')
Sdstr.sendwait ("{tab}")
End Sub
Use Shell to invoke external programs in vb.net:
Copy Code code as follows:
Shell (pathname as string,[style as
Microsoft.visualbasic.appwinstyle=2],[wait as
Boolean=false],[timeout as Integer=-1]) As Integer
Call Explorer
Copy Code code as follows:
Dim pid As Integer
PID = Shell ("Explorer.exe http://vbnetcn.126.com",
Microsoft.visualbasic.appwinstyle.normalfocus, True)
Calling the default program
Copy Code code as follows:
Dim pid As Integer
PID = Shell ("Start.exe mailto:vbnetcn@163.com",
Microsoft.visualbasic.appwinstyle.hide, True)
Use the Microsoft.visualbasic.appwinstyle.hide parameter to hide the program
The DOS window that jumps out at run time.
SendKeys is a function to simulate keyboard messages, let's not talk about Windows message driver to consider sendkey this function simply
SendKeys since the analog is a keyboard message, then he can only simulate the keyboard can enter the message, such as
SendKeys ("ABCD")
Actually, it's not the script that sends the "ABCD" string out.
But analog keyboard input, the equivalent of the keyboard click on a and then click b in the click of C ...
Join the key message sent by QQ chat box has been, then we all know that his approach is to display English letters in the chat box
But we found that the addition of Sendkey analog input characters, it seems to be unrealistic, because the keyboard does not have the Chinese button ....
But we have to enter our Chinese characters chat content, so what can we do?
From the principle, sendkey is actually a function of sending a specific message in Windows (I guess he sent the wm_syskeydown message, I haven't tested ha ^_^)
If we want to send the contents of the Chinese Character chat box, we'll also start with the Windows Messaging mechanism, find the handle to the chat message first (you can take advantage of the FindWindow function or use the Spy tool), and then find the handle to the chat box above, and then we can think of this handle to send Wm_ The news of the SetText.
Rough.
