C# Selecting/Detecting Runescape window

[n3ss3s]

I need to do what SCAR/Simba does when you drag the crosshair over scape, except for without the crosshair and the dragging, so basically I need to get the RS window coords, or some kind of a handle n shit

tips ples :sasmokin:

[Cazax]

What I have in Delphi...

procedure TForm1.BitBtn3MouseUp(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);
var
tp : tpoint;
Begin
GetCursorPos(TP);
RS_Handle := WindowFromPoint(TP);
End;
what I found on google about C# WindowFromPoint:

[DllImport("user32.dll")]
public static extern IntPtr WindowFromPoint(Point lpPoint);

[DllImport("user32.dll")]
public static extern bool GetCursorPos(out Point lpPoint);

public static IntPtr GetWindowUnderCursor()
{
Point ptCursor = new Point();

if (!(PInvoke.GetCursorPos(out ptCursor)))
return IntPtr.Zero;

return WindowFromPoint(ptCursor);
}¡
Hope that helps :p

[n3ss3s]

I'm almost a 100% sure that will get the whole window (e.g FireFox, not just the RuneScape applet) :(

Simba is open source

Simba is open source

But Simba is pascal isn't it?

EDIT: And heres the thread where I discussed this: http://villavu.com/forum/showthread.php?t=54922

[n3ss3s]

Looks good, I'll try porting it although I'm a complete noob to .NET and all of that :)



(No FindWindowBySize isn't a cool solution).

loled irl

[Frement]

I would love to hear where you are going to use this, and maybe see the ported version?

You can add me on MSN if you want: frement@windowslive.com

Jos muistan oikein ni olit suomalainen? ;)

[n3ss3s]

Olen suomalainen, I live in the US nowadays so I'm rarely on at the same time as GMTers, I'm actually trying to make an utility that some people here will propably hate on, a pin logger that is...

[Frement]

A "pin logger", like you log the bank pins? To what purpose if I may ask?

[3Garrett3]

Judging from his post, malicious purposes? If we'd hate on it :p

[Cazax]

Good luck reading the numbers on the pin screen :p

[n3ss3s]

Good luck reading the numbers on the pin screen


Problem?




EDIT: Well well well, if it isnt Mr SunAwtCanvas

http://i51.tinypic.com/29c77kp.jpg

Posting code later today, not quite finished


EDIT: YES!!! THERE IS A GOD! Found out my bitmap copying was flawed and spent hours probind the DC shit for nothing lol


As I promised: (If this is any use for anyone, esp. if the problem with grabbing the canvas still persists feel free to use this if its any use)

Also, not going to take shit for not shortening code by 2 lines at some possible places, first time with C#

[Freddy1990]

I'm almost a 100% sure that will get the whole window (e.g FireFox, not just the RuneScape applet) :(

I'm almost 100% sure it won't get the whole window... GetCursorPos + WindowFromPoint for the handle, GetWindowRect to get the window position to calculate relative coordinates :)

Only thing you rly need to dig into the client for is sending keys :)

[mastaraymond]

But Simba is pascal isn't it?
Yes.. And you are capable of reading pascal, so what was your point again ;)

No, that's how you get the firefox window, you have to loop into the sun canvas... Posted the source above so no flame m8... Got everything working fine but now I'm getting a System.ArgumentException it a context that has a notorious reputation for random exceptions :mad:


Also above answers the

EDIT: managed to fix the shitface, was somehow caused by 2 pretty much consecutive calls of the method that uses getpixel, idk why but now its done..

I don't see how that was flaming, but ok... Here's proof: http://freddy1990.com/files/ClientSel.rar
Open RS in firefox, drag the crosshair over it, see where ur cursor hits 0,0 on the app.

(Srr the app isn't pretty, but I hate using a touchpad xD )

[n3ss3s]

Hmm, well to be honest I didn't actually try the mouse method as somehow at the time it seemed it would return the same handle as GetDesktopWindow... Also I didn't really mean that you were flaming me ;)

[Freddy1990]

Yea, np, basically, you get other windows when you select the desktop because you can't actually see the desktop window, it's overlapped by a bunch of other windows that make up the desktop. For example, aside from the taskbar, you have a big empty space with your icons and background, you might think that would be the desktop window, but it's basically a big listview. :)

[n3ss3s]

Woops sorry I meant GetForegroundWindow but yea...
