OK, so BBB GUI doesn't seem to be supported any longer and BlueGUI died long before that but I have been dabbling with BBB GUI again it seems that the commands to enable/disable a window are missing.

BBB WINDOW_SETDISABLED
BBB WINDOW_SETENABLED
BBB WINDOW_GETENABLED

These commands are in the keywords file but not the dll.

So unless Brendy Boy comes along with an update to BBB GUI does anyone know of a way to do this manually - perhaps a call to user32?

Thanks

I haven't tried it but these should be the relevant functions:

+ Code Snippet

#constant user32 1

function SetWindowEnabled(hWnd as dword, bEnable as boolean)
    bStateChanged = call dll(user32, "EnableWindow", hWnd, bEnable)
endfunction bStateChanged

function IsWindowEnabled(hWnd as dword)
    bIsEnabled = call dll(user32, "IsWindowEnabled", hWnd)
endfunction bIsEnabled

I checked the BBB GUI.dll with dumpbin and checked the resource string table. The functions are there and properly linked in. My keyword file shows the functions as -

ENABLE WINDOW
DISABLE WINDOW
WINDOW ENABLED

Thanks Rudolpho but that doesn't seem to work

This is what I tried:

+ Code Snippet

#constant user32 1
load dll "user32.dll", user32
bbb app_start

dbp = bbb APP_GETDBPROWINDOW()
window = bbb Window_make (50, 50, 100, 100, "Mw Window", dbp, WS_OVERLAPPED)

repeat
	text 0, 0, "is Enabled: " + str$(IsWindowEnabled(window))
	if shiftkey() then	SetWindowEnabled(window, 1)
	if returnkey() then SetWindowEnabled(window, 0)

until spacekey()

bbb app_end
end


function SetWindowEnabled(hWnd as dword, bEnable as boolean)
	bStateChanged = call dll(user32, "EnableWindow", hWnd, bEnable)
endfunction bStateChanged

function IsWindowEnabled(hWnd as dword)
	bIsEnabled = call dll(user32, "IsWindowEnabled", hWnd)
endfunction bIsEnabled

The isEnabled function was reporting 1 - always but setEnabled had no affect.

WickedX - It seems you have an older version of BBB GUI before he changed all of the keywords. Would you mind uploading it please? I might be able to utilise some of the working commands from the older dll.

Thanks

Unfortunately, I just updated. I have found errors in the string table for these functions and have corrected them. Attached are the updated DLL’s.

Edit: I made an error this time. This error only affected BBB GUI no_uskin.dll. Download corrected, works now!

+ Code Snippet

bbb app_start

dbp = bbb APP_GETDBPROWINDOW()
window = bbb Window_make (50, 50, 100, 100, "Mw Window", dbp, WS_OVERLAPPED)

repeat
   cls
   text 0, 0, "is Enabled: " + str$(BBB WINDOW_GETENABLED(window))

   if shiftkey() then BBB WINDOW_SETDISABLED window
   if returnkey() then BBB WINDOW_SETENABLED window

until spacekey()

bbb app_end
end

@Scraggle: It is possible that the handles returned by the BBB Gui plugin aren't the actual window handles (this is the case when using BlueGui at least, where you could call a special function to get the actual window handle from the gui references); you could look around the documentation if there are any such functions in BBB. I've never used it myself.

There's actually no documentation at all with BBB GUI. It's all very much trial and error.
However, the dll's that WickedX uploaded work perfectly. I'm not sure what you did to them but things are great now.

Thanks to both of you for your help

Happy to help. I have flagged this thread with a MailBack. Post back, if you have any more problems. 99 times out of a hundred, it's probably just an error in the stringtable. Easily corrected in a resource editor.
