Hello,

I'm new. I'm developing an application with VB.NET that must be able to open a window and compile some fields using only keyboard button...

The first field have to write a code like "0542645" then have to focus to another textbox with the TAB button and so on. I'm using WINDOWS 10.

Have you any ideas?

Thanks.

What I have tried:

The problem is that the classic SendKeys function doesn't work in that program, I tried the same code with the "Notepad" and it works. Is there any alternative? I tried also to use SendMessageA script but nothing.

did you try Using both SendKeys.Send() and SendKeys.Sendwait() ??

Yes but it doesn't work!

Unless you're "opening a window" in the application you're writing you're actually launch an outside process/application. You would never use SendKeys inside your own application.

Now, what's the external application? Whether or not SendKeys works depends on the application you're sending keystrokes to.

For testing I wrote this code:

Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
SendKeys.Send("C")
SendKeys.SendWait("C")
End Sub

and it works with the notepad. The application I would to use is a management software.

That doesn't answer my question at all.

Basicly SendKeys could work ... but if it works like you want depends on to what you send AND if the Destination allready has the Focus ...
You should give much more Information ...

I put the code into a timer, so I tried to get the focus manually, but it doesn't work.

Do you have realized that I'm not sitting beside you and see what you have done and how you done it ?
So ... once again : you should give much more information ...

Solution 1

Maybe you can try PostMessage, see: VB.NET Sending Strings via Postmessage - Stack Overflow[^]
Another option would be to use a utility like [AutoHotkey]

PostMessage doesn't work. AutoHotKey I don't know how it works, I tried to import the DLL from Visual Studio but I don't know how to use that function
