Which version of Windows are you running? The problem might
be that you are using pre-Windows 98SE2. I think the IDE works
for Windows after that one.

Probably too old...
Try Windows 2000 or XP(not ME, I've heard it is worse than 98),
they are somwhat more stable.
2000 is less expensive and easier to set up,
but XP looks better and has some extra features(and microsoft
will support it longer.)

I'm afraid this is not an IDE problem, but a 0.60.6 problem.

I use win98SE2 as well. As it bears a full screen splash Windows logo, I'm 
curious to know how it's pre-Windows.

I upgraded to 0.60.6 recently (see my post on last sunday UTC), but had to go 
back to 0.60.3. I can't create an EditText or a RichEdit control under 0.60.6, 
it fails with error 461 as well.
Under 98ES2 and using 0.60.3, IDE and my apps work fine, thanks.

Problem with RichEdit creation    CChris
   Oct 17, 2004 06:51 PDT


posted by: CChris <christian.cuvier at agriculture.gouv.fr>


The following code (pared down from original) seemed to work correctly until
a few days ago:

include win32lib.ew --
include database.e
include xcontrols.ew --

global object win, code

                 win = create(Window,"Test",0,1,1,400,400,0)
                 code = createEx(RichEdit,"",win,10,40,380,350,0,0)
--               code = xControl(Syntax,"",win,10,40,380,350,0,0)

I updated xcontrols from an 2-3 year old version, and from win32lib 0.60.3 to 6.
Now I'm getting an error 461 (Failed to acquire a hWnd when creating a control).
And SynTest.exw (the test file supplied for the Syntax control) fails the same.
Failure occurs at the createEx line. If you comment it and remove the comments
of the line beneath, then line 203 in Syntax.ew (the createEx statement at 
line 203)
fails with error 461.

Any idea about what can go wrong?
Other randomly selected win32lib demos work correctly.

Yes, I noticed that too :)
It may happen when resources start running low as well. In that case, the 
error location is random and closing an app generally cures it all (rebooting 
always does); this is an easy signature for this flavor. The problem I have is 
very stably reproducible.

The facts I gathered after the post I just joined a copy of are:
1/ xcontrols is just a victim, not a cause;
2/ database.e has nothing to do with it, should have removed that line;
3/ WC_RICHEDIT is "RICHED20A" as expected; copying the riched20.dll from the 
office machine didn't help.

I'll take time to trace through createEx, but I find it hard to identify which 
w32Func() does what: how can I translate the value of funcid  into some 
human-readable API call?

I know about another user (why he did not post I don't know) who got exactly 
the same problem: code crashed on the win98 laptop and runs fine under XP, now 
that that machine is up and running again. That was not the case before he 
upgraded to 0.60.6, I don't know what the older version was.

Maybe I can help,

I had the same problem with 60.6, then, I remembered Derek provided a fix
for 60.5. When I looked in my download of 60.6 the fix had not been added.
After adding the fix as per Derek's post bellow my version of 60.6 works... a
ok!

Hope it helps

I messed up with RichEdit on old Windows systems.

Look in the w32DLL.ew include file. Naar the end of the file you
will see some code dealing with RichEdit classes. Replace
all after the comments ...

--/topic Constant
--/const riched32
--/desc Windows Library: Rich Edit Control

with ...

global constant
riched32    =
    registerw32Library({"Msftedit.dll","riched20.dll","riched32.dll"}),
   -- Rich Edit control
    WC_RICHEDIT10       = "RICHEDIT",
    WC_RICHEDIT20       = "RichEdit20A",
    WC_RICHEDIT50       = "RICHEDIT50W"
global sequence WC_RICHEDIT

vw32Libraries[riched32][1] = linkDLL(vw32Libraries[riched32][2])
if vw32Libraries[riched32][1][1] = 1 then
    WC_RICHEDIT = WC_RICHEDIT50
    
elsif vw32Libraries[riched32][1][1] = 2 then
    WC_RICHEDIT = WC_RICHEDIT20
    
else
    WC_RICHEDIT = WC_RICHEDIT10
end if

Oh my sainted aunt! How could I have missed that! I've now put that fix
the next release (for sure!).

I still can't see any problem with EditText controls though?

No, Derek... but thanks! I'm looking at that now.

The problem I had with 0.60.6 you actually provided some patched code for,
but subsequent problems occurred for which I never saw fixes. Let me see
if I can come up with what it was and I'll get back to you.

Thanks, again! :)
