Hello,

The MAXARGSTRINGS has to be inserted in the first lines of the global program.
I just tested it with v12 and its working fine.

hi, thanks, but it does not working for me.
I wrote the line:
SYS MAXARGSTRINGS=8196
in the very first line of my global program and I get the msg inthe evt-viewer:
[SCADA Basic] MAXARGSTRINGS is set to 8191 (Max:8191),
so seems to be accepted, but i am getting still the msg in the evt-viewer:
2017/12/05,11:47:04.736,6,W,,1,pcvue_test,1,CopyField, the size of the string to copy is too large, size=2689 max=2047 string= 10Header

If you see the code, the interesting point is, that I never use the big string in a str-var, hmmm.

also confusing, what Armin told me right now, is, that following is written in the example-field of the help :

Examples

Sub func1 ()

‘--------local variable

Dim cMystring as STR;

cMmystring = Addstring(“”, “…..”); ‘up to 32000 chars

For the copyfield message you must make a SPR. This message appears when PcVue tries to set a string bigger than expected but that's INTERNALLY. Meaning it looks like your MAXARGSTRINGS is well taken in account but there is another error. I bet the issue is coming from the instruction LEN

Don't forget giving your project + procedure to reproduce with the SPR

And then, another SPR for the help as 32,000 chars is the limit for the PcVUe Text variables and not the Scada Basic strings.

ooopps click Submit too fast.

So, try allocating your buffer with a fixed large value instead just the Len(Window("GETCOLLECTION")).

I bet no more CopyField 😉

Nico

And why are you doing this?
SEQ_BUFFER("INSERTFIELD", 1, hbuffer, "", Window("GETCOLLECTION"));

There is no help for that, so I could only use the examples from Anna.
I think it is because of the formatting?
I will ask Anna / Nico D.

By the way, how do you format the SCADA BAsic in the forum into the Editor-style?

And no, using intvalue = 10000; did not help. same msg.

Arrrgh I lost my bet 🙁

To format your text you must use the icons up to the smileys.
Select your text, click the icon representing a document having xml tags (16th icon from the left)

Nico

WINDOW("GETCOLLECTION") already returns a buffer

Dim hBuf as long;

hBuf = WINDOW("GETCOLLECTION");

'whatever you want

FREE_BUFFER(hBuf);

really?
print(Window("GetCollection")) will print the xml inside, so for me it is string , no?

but,

print(Alloc_buffer(1000)) will print a long?

maybe I missanderstand something?

My bad. I misunderstood what Nicolas D. told me.
The function returns the xml String.

Dim sXmlContent as str;
Dim hXmlBuf as long;

sXmlContent = WINDOW("GETCOLLECTION");
XMLPATH("LOAD", "CTX1", sXmlContent);


'Whatever you want

XMLPATH("UNLOAD","CTX1");

XMLPATH should work with an input string, but if not, SEQ_BUFFER("PUT_LINE",...) is probably easier to use and understand than INSERTFIELD.

hi,

I tested line by line and the

SEQ_BUFFER("INSERFIELD",1,buffer," ", Window("GetCollection"))

causes the error-msg.

Why Put-line should be the better way?

in your example, the problem will be the limit of 8196 chars for string vars, when you have about 15 mimics opened, but right now, it could be a solution.

:sick:
using a string variable, same error-msg appears, but with limit of 255 :blink:
so no workaround?

@Florent: You said you tested and everything works? I used latest nightly build.

I think I will create some SPRs
1. sys param is not taken into account on str-vars and on "Buffer-Transfers"
2. Doc SPR for the 32000 chars
3. wish spr to increase size of str-vars

Hi Johannes,

I got your original code and checked.
It is working well if you start like that:

 	sXmlFileName = "CTX1";
 	intvalue = 10000;
	hbuffer = ALLOC_BUFFER(intvalue);
	put_buffer(hbuffer, 0, Window("GETCOLLECTION")) ;
	XMLPATH("LOAD", sXmlFileName, hbuffer); 
	
	Count = XMLPATH("COUNT", sXmlFileName,"Mimics/Mimic");
	
	for (i=1; i<=Count;i++)

	'---- here your treatment

	next

The copyfield messages are still here (therefore you still must do your spr) but it works.

Nico

No SPR on the MAXARGSTRINGS except if you have an error message similar to tis one:

2017/12/06,09:14:19.685,6,W,,9030,,1,BASIC,The Size of parameters is too large, MaxSize=8001 params=
2017/12/06,09:14:19.685,6,A,,9030,,1,BASIC,Program (p) Branch () Line 27
2017/12/06,09:14:19.685,6,A,,9030,,1,BASIC, Check SYS MAXARGSTRINGS in global program (Default: 2047). String overflow caused by parameter 2

I've only seen copyfield errors that are linked to buffer manipulation.

It may also come from the GETCOLLECTION instruction which returns a string. I have to check something with Nicolas D.

To check the MAXARGSTRINGS is correctly interpreated, try to concatenate strings over the fixed limit

Sub TestMaxArgStrings()
	Dim i as integer;
	Dim s as str;
	
	while (i<=900)
		s = addstring (s,"$........ ");
	Wend

End Sub
