Hi. I need to simulate keyboard and mouse events. For the first step,
I tried to move mouse using SendInput. But it didn't work. I searched
all over the internet for an example, but only questions were there.
Please give me what was wrong in the following code. I simplified the
code so that you can just copy it to a console app project, and run
it. Thank you for any help.
PS: I need to work with SendInput the way it is, not SendMessage or
modified INPUT structure, because there are a lot of other things to
do with SendInput.
Thank you.

While wating for a reply from kind people, I tried myself that code in
native C++ code.
#include "stdafx.h"
#include "windows.h"
int _tmain(int argc, _TCHAR* argv[])
{
MOUSEINPUT mi;
mi.dx=0;
mi.dy=0;
mi.dwExtraInfo=0;
mi.dwFlags=MOUSEEVENTF_ABSOLUTE|MOUSEEVENTF_MOVE;
mi.mouseData=0;
INPUT pInputs[1];
pInputs[0].mi=mi;
pInputs[0].type = INPUT_MOUSE;
SendInput(1,pInputs,sizeof(INPUT));
return 0;
}
It just worked fine. Why the C# code below doesn't work?
Please give me a hint. Thank you very much.

I have found out the reason. My Windows is 64bit version and the .NET
app becomes 64bit application. I changed the build option to x86, and
it worked.
Still don't know why the same API call fails if the .NET app is 64bit.
Do you know why?

I believe all the FieldOffset(4) must be FieldOffset(8) when running
as a 64-bit app.
Since you're only using the MOUSEINPUT part of the union, and it
happens to be the biggest one of the three, you can remove the other
two and change the declaration of INPUT to
struct INPUT
{
public int type;
public MOUSEINPUT mi;
}
That should hopefully make the code work on both 32-bit and 64-bit.
