AutoitX Help

[xZZTx]

im starting AutoitX and i was just wondering how todo a few things

#include <Windows.h>
#include "AutoIt3.h"
int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR   lpCmdLine,
                     int       nCmdShow)
{
    int $T;
    $T = AU3_PixelSearch(0,0,1000,900,0xFF0000,NULL,NULL,NULL);
    if (AU3_error() == 0)
    {
        AU3_MouseMove($T[0],$T[1],NULL);
    }
    return 0;
}

Error

Please Explane the error to me

thank you in advanced

You obviously don't know C++. If you knew C++, part of the error would be obvious.

AU3_PixelSearch doesn't have a return code.

You didn't pass a pointer to a point to receive the location of the found pixel.

You are attempting to subscript an integer.

There may be other errors but those are what I see immediately.

[xZZTx]

alright then..

could you please explane how i should write this, a few examples would help me learn this faster

[Richard Robertson]

You should learn C++ first. Once you have that down, then you can extend it with other things.

[xZZTx]

i know i should learn C++ 1st but the thing is i don't really have time for that

so with a simple syntex setup i could learn what i need/want to use

[Richard Robertson]

Well there are two ways I could help you. I could just rewrite that small piece of code. Or you could ask specific questions and learn. I'd much rather you learn from it.

#include <Windows.h>
#include "AutoIt3.h"
int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR   lpCmdLine,
                     int       nCmdShow)
{
    POINT T;
    AU3_PixelSearch(0,0,1000,900,0xFF0000,NULL,NULL,&T);
    if (AU3_error() == 0)
    {
        AU3_MouseMove(T.x,T.y,NULL);
    }
    return 0;
}

I want to say it's something like that. This is close anyways.

Thank you for the help now i understand how part of this works..theres just a bit of a snag..

Unhandled exception at 0x1001b52b in Test.exe: 0xC0000005: Access violation reading location 0x00000008.

[Richard Robertson]

Can you running in a debug mode? It should drop to a break point when you run that. Let me know at what line that error happens.

[xZZTx]

it brakes on IF and on MouseMove

and T.x & T.y are returning numbers so that can't be the error

Edited March 7, 2009 by xZZTx

[Richard Robertson]

Try using -1 instead of NULL on the mouse move.

[xZZTx]

still not working...have you tried the code yourself?

maybe its jsut my settings

[Richard Robertson]

Nope. I don't ever use AutoItX. I just try to help if I can.

I'll look at it again after dinner.

[Authenticity]

Don't send the parameter for the step to null, it's supposed to incremented each iteration so 0 probably is causing the error, send 1, it's the default. Even though, I don't know if this is the reason.

[Richard Robertson]

That would make sense actually. I just never use AutoItX and didn't even bother looking at the help file deeply.

[xZZTx]

AU3_PixelSearch is the error

even if i don't use what it outputs it makes it error

{
    POINT T;
      AU3_PixelSearch(1,1,1000,900,0xFF0000,30,1,&T);
    if (AU3_error() == 0)
    {
    int T1 = 300;//T.x;
    int T2 = 900;//T.y;
        AU3_MouseMove(T1,T2,1);//Error on this line
    }
}

as to

{
    POINT T;
    //AU3_PixelSearch(1,1,1000,900,0xFF0000,30,1,&T);
    if (AU3_error() == 0)
    {
    int T1 = 300;//T.x;
    int T2 = 900;//T.y;
        AU3_MouseMove(T1,T2,1);//No Error At All
    }
}

[Authenticity]

Dunno why it's referring to and causing this access violation like MOV ECX, [EAX+8] and EAX is 00000000....

[Richard Robertson]

Try changing it to

POINT *T = new POINT();
AU3_PixelSearch(1,1,1000,900,0xFF0000,30,1,T);

And then change T.x to T->x and T.y to T->y. See if that works.

[Authenticity]

I can't be right but maybe no check is done in the function for null pointers? or nothing like __try..._except?

[xZZTx]

still didn't work...

could we get a AutoitX expert down here..
