Hi,

In VB.NET win forms,
Using SendInput Function.
In its call, it uses a INPUT structure using a KEYBDINPUT structure.
In KEYBDINPUT we can set dwFlags with KEYEVENTF_KEYUP (a const = 2)

But when we use it, it is still as pressing a key, not as a release key event. So, we can send a SHIFT down event, but not able to send a SHIFT keyup in order to unshift.

Same thing with any letter. Even if we set dwFlags with KEYEVENTF_KEYUP, it types again the letter.

Thanks
Marc

Any tips about that bug?

Thanks
