I read on the LB forums that WML can be used to check the states of buttons?? i.e. clicked and released If so can someone post an example, as I can find anything over there.

Hi Tasp, How are you creating the buttons? There's already a demo on this site to trap simple clicks for API-created buttons. http://www.b6sw.com/forum/content.php?mode=snips2&p=747 _________________ Brent

This is what I have done so far, I'm just waiting for the code to tell me when the button has been pressed and then when it's released.

Code:

nomainwin
WindowWidth = 200
WindowHeight = 250
stylebits #1, 0, _WS_MAXIMIZEBOX or _WS_MINIMIZEBOX, 0, 0
fontname$ = "Wingdings 3" + chr$(0)
height = 60
GOSUB [create]
'q, p, t
'f, g, h, i
button #1.b, "f",[left],UL,10,70,60,60 'left
button #1.c, "g",[right],ul,120,70,60,60 'right
button #1.d, "h",[up],ul,65,10,60,60 'up
button #1.e, "i",[down],ul,65,130,60,60 'down
button #1.f, "P",[zoomin],ul,15,145,40,40 'zoomin
button #1.g, "Q",[zoomout],ul,135,145,40,40 'zoomout
MENU #1, "Menu", "Connect", [branchLabel], "text2", [branchLabel2]
open "Cam Ctrl V1.0" for window as #1
print #1, "trapclose [quit]"

I have made this code using your telnet.mesock demo

But when I close the program after connectioning it crashes LB,

any ideas?

Code:

I posted a reply to your question on this same subject on the LB Conforums, but to keep help anyone reading this first, I'll repost it here.

Here's a partial solution:

Code:

Open "WMLiberty" For DLL As #wmlib

Button #demo.btn, "Hold me", [click], UL, 10, 10, 75, 25

Open "Button Down Demo" For Dialog As #demo

#demo "TrapClose [quit]"

hwnd = HWnd(#demo.btn)
Callback lpfnCB, OnLButtonDown( ULong, ULong, ULong, ULong ), Long

CallDLL #wmlib, "SetWMHandler", _
hwnd As ULong, _
_WM_LBUTTONDOWN As ULong, _
lpfnCB As ULong, _
-1 As Long, _
ret As Long

[wait]
Scan
CallDLL #kernel32, "Sleep", 100 As Long, ret As Void
GoTo [wait]

[quit]
Close #demo
Close #wmlib
End

[click]
#demo.btn "Hold me"
GoTo [wait]

Function OnLButtonDown( hwnd, umsg, wparam, lparam )
#demo.btn "Let me go!"
End Function

I say partial because it doesn't take into account the possibility of the user pressing the button with his space bar. According to the docs (SDK), the proper way to trap state changes is to create an owner-drawn button. However, that's quite complicated. If anyone is interested and I get some time, I'll probably post a demo using OD on my site in a few days.

Sorry, I don't think I be of much help. I've never used mesock, but I've heard that it gives people problems on occasion.

Besides, it's hard to read your code. If you invest the time to format it and give things better (more descriptive) names, errors might pop out at you (or others) much more easily.
