1. Win32lib setText
Hey all,
Using Win32lib v.59.1 I seem to have an issue with setText to SLE Edit
controls.
If I specifically send a string sequence e.g; setText(Diag[i],"work")
this seems fine but, if I return a string sequence from a buffer it doesnt
work correctly.
Has anyone else ran across this?

Its not much use just saying "it doesnt work correctly" because that does not
give us any information to help you. It would be better if you said what *does*
happen rather than what does not happen. For example, is it displaying nothing or
displaying strange characters? And what does "return a string sequence from a
buffer" actually mean? I guess you are using an API functon which is returning a
zero-terminated string at a RAM location and you are getting that string out of
RAM and converting it to a sequence then using setText(). Can you see what is in
the sequence-string before calling setTExt() using the trace or even the '?'
method? What is the contents? Are you sure you are fetching the string correctly
from RAM? What is the API routine you are using? Is it just this API routine or
all API routines that return a RAM string? Can you display the sequence string in
a console window?

There must be more than one way to retrieve a string from a buffer, I know
of only one way...
sorry for not being specific.

No (0) string is inserted into the SLE.

No (0) string is inserted into the SLE. (nothing displayed)

Your a very good guess Derek,
I need to know how to convert the z-string to a sequence suitable for use
with setText

YES! The string /s do show up in a console window, this makes me think there
may be something wrong with setText or,
Im not sure how I need to convert the z-string to acceptable sequence
suitable for use with setText

I continue to no problem with this on my system. Here is some example code...
---------------------
without warning
include win32lib.ew
integer Win, TPath, Btn
Win = create(Window, "Temporary File Path", 0, 0,0, 400, 200, 0)
TPath = create(SleText, "NOTHING HERE YET", Win, 10, 10, 350, 25, 0)
Btn = create(Button, "Get Path", Win, 10, 55, 100, 25, 0)
procedure Click_Btn(integer self, integer event, sequence parms)
atom addr
sequence temp_path
integer len
len = 255
addr = allocate(len)
if w32Func(xGetTempPath, {len, addr}) then
temp_path = peek_string(addr)
else
temp_path = ".\\"
end if
free(addr)
setText(TPath, temp_path)
end procedure
setHandler(Btn, w32HClick, routine_id("Click_Btn"))
WinMain( Win, Normal)
---------------------
Again, I ask ... What does the sequence contain? In other words, can you show
me, in a reply email, the elements that make up the sequence you are trying to
set the SLE to?

5. Re: Win32lib setText
Hey guys,
Never mind, but thanks alot...seems this one was a issue where someone
had cleared the control sequence just before calling setText so no control
ID's where retained and this threw me off.
Darned code!
I couldnt explain this until I started to write a better demo for Derek
so Derek, you indirectly solved my problem.....Thank you!
You read this bubbashrimp your program is fixed....
