Hi.

I am trying the demo version of the http://www.nbit.net.au HTML editor with pureDispHelper.

This crashes with "invalid memory access" on dhReleaseObject.

Code: Select all

dhToggleExceptions(#True)
OpenWindow(1, 0,0, 800,600, "Test")
CreateGadgetList(WindowID(1))
ContainerGadget(1,10,10,600,300)
CloseGadgetList()
;         oEd = dhCreateObject("rmpHTML.HTMLEd", WindowID(1)) ; Okay, but fills window
oEd = dhCreateObject("rmpHTML.HTMLEd", GadgetID(1))  ; Okay
Debug oEd
Repeat
Until WaitWindowEvent()=#PB_Event_CloseWindow
dhReleaseObject(oEd) ; Crash if windowID or gadgetID used in dhCreateObject
                     ; --  Invalid Memory Access --
                     ; Crashes on first internal IDE comment line following this line.
                     ; so assume it is this line

If I don't use the windowID or gadgetID in createobject, it fails to load.
If I do use either, it loads and is editable but crashes with "invalid memory access" on release.

Also:
No errors are reported but setting/getting properties fails (just doesn't happen). Eg:

Code: Select all

w.s="<div>abc</div>"
dhPutValue(oEd, ".DocumentHTML = %s", @w)

I am obviously missing some major point here.

Can anyone help?

Aside and on another note altogether. How do you pass a word (2 byte integer) value in dhPutValue? ("%w" is not recognised).

Using the OCX_CreateGadget() function works fine.

Code: Select all

oEd = OCX_CreateGadget(2, 10, 10, 600, 300, "rmpHTML.HTMLEd")

Ah!

Thank you!

(With OCX/COM and PureBasic I feel like I am running along a narrow beam '000s of ks above the ground - with my eyes closed on a pitch black night)

EEEEeeeeeeeyyyYYAAAAaaaaaa.

Or you should close your window before program end, see the examples,
always CloseWindow(0) before end

Ah yes. That also fixes it.

My bad there. Thanks!

This works quite nicely now with the OCX_CreateGadget function.

I sometimes get a "invalid memory address" error in the waitwindowevent loop after editing table properties but I think that might be the control not releasing the table and contents and so PB is suddenly given an unknown gadget (the table). Guessing.

But we advance.

Thanks again.
