Application.captureMouse in Flex 3

[Gert]

Hi,

I want to track "user activity" on a windows system in order to know if he is active or away from the pc. (like in messenger)

A good way to do this would be to track mouse movement and reset a timer when the mouse is not moving.
I thought about Application.captureMouse but I don't see how to use this in Flex 3.

Any hints?

tnx,
Gert

I found a solution (workaround?) for myself:


struct {
long x;
long y;
} POINT;

dllimport "user32.dll" stdcall Boolean GetCursorPos(POINT*);

function traceWin() {
var output = new Object;
output.value = new Struct(POINT);
GetCursorPos(output);
//var hwnd = WindowFromPoint(output.value);
trace(output.value.x);
}

Application.setInterval(traceWin, 1000);


Checking the x and y values for changes will let me know if the user is away or not.


Probably not the most elegant way of doing this: any other hints are very welcome.

Watching only the mouse events may not be enough. On win2k,xp,vista you can use the "GetLastInputInfo" method.

Thank you SWFKit: this is indeed a much better solution.
I love your support: this is *the* reason why our company sticks with SWFKit (despite its outdated looking IDE and scripting environment)

Hm, I was a little bit too fast ... I can not make this work:

here's my ffish code, but output is "0 - 0" ...

struct {
long cbSize; //uint ~ long ?
long dwTime; //dword ~ long ?
} LASTINPUTINFO;
dllimport "user32.dll" stdcall Boolean GetLastInputInfo(LASTINPUTINFO*);

function pollLastInputInfo() {
var lastInput = {cbSize:32, dwTime:0}; //is 32 the right size?
lastInput.value = new Struct(LASTINPUTINFO);
GetLastInputInfo(lastInput);
trace(lastInput.value.cbSize + " - " + lastInput.value.dwTime);

}
Application.setInterval(pollLastInputInfo, 1000);

struct {
  long cbSize; //uint ~ long ?
  long dwTime; //dword ~ long ?
} LASTINPUTINFO;
dllimport "user32.dll" stdcall Boolean GetLastInputInfo(LASTINPUTINFO*);

function pollLastInputInfo() {
  var lastInput = new Object;
  lastInput.value = new Struct(LASTINPUTINFO);
  lastInput.value.cbSize = lastInput.value.structSize;
  GetLastInputInfo(lastInput);
  trace(lastInput.value.cbSize + " - " + lastInput.value.dwTime);

}
Application.setInterval(pollLastInputInfo, 1000);

aah - structSize, that was what I was seeking for ...

thanks! It works now!
