Programming / Link File vs. Prefix File
« on: August 22, 2023, 09:25:38 AM »
As far as I understand the documentation both file types do the same. So what are the pros and cons? Which one is better when starting to use SQL-tables?

Thin Client/WindX / pxplus.exe as Citrix-App
« on: August 15, 2023, 08:22:40 AM »
Are there any known issues when running WindX as a Citrix-App?
A customer has 3 out of 300 users where the invocation string of pxplus.exe is truncated by 4 bytes.

Programming / update global functions at runtime
« on: August 04, 2023, 05:56:43 AM »
Each time we update global functions on a Windows system they don't work any more. PxPlus throws many types of errors depending on how the functions have changed. Here is what we do in order to update/reload the global functions:

Code: [Select]
bkpPC = prm('PC')
set_param 'PC' = 0
! do update actions
set_param 'PC' = bkpPC
drop pth("globalFunctions.pvx"), err = *next
call "globalFunctions.pvx" ! addr itself

What needs to be done for a successful update?

Programming / corrupted journal files
« on: July 11, 2023, 08:10:14 AM »
Each time a record with a large text field is written to a file with active journalization, the current journal file becomes corrupted.
As we cannot predict the requested field length, we define such fields with a length of 100 bytes delimited and turn on "extended records". We must always lie about the length in such cases. PxPlus has no problems with file I/O to the data file. So the 100 bytes are a signal for the developer, that there may me much more bytes.
We expect the journal file to be written as properly as the data file. How can we avoid the problem?

Programming / Re: Strange if then else behavior

The issue is a result of the line oriented nature of the language.  IF ... THEN ... ELSE ... will basically process what is on the line.

This rises the question how does PxPlus find the closing curly braket? Are there any performance aspects?
As I don't like premature RETURNs or EXITs my coding style looks like this.
Code: [Select]
SUB_ROUTINE:
if condition {
txt$  = "Are "
txt$ += "these "
txt$ += "lines "
txt$ += "processed "
txt$ += "in "
txt$ += "some "
txt$ += "way "
txt$ += "during "
txt$ += "execution "
txt$ += "in "
txt$ += "order "
txt$ += "to "
txt$ += "find "
txt$ += "the "
txt$ += "closing "
txt$ += "curly "
txt$ += "bracket?"
print txt$
}
return
Would that routine be faster using a premature RETURN?

Thank you. I'll take a look at it.

Devon,

I want to drag files from a PxPlus listbox and drop it on a control of an external application.

I have a listbox containing filenames and want to drag a file from it to another non-PxPlus-application. How can I do that?

Nomads / Re: cell editing

I wasn't aware of 'GridMLVersion'.
That comes close, yes. I hope they accept it.
Thank you.

Nomads / cell editing
« on: July 28, 2022, 03:09:00 AM »
A customer wants to end cell editing with <ENTER> and move to the next editable cell according to the tabmode.
I tried:
Code: [Select]
preinput [next] $09$ ---> does nothing
preinput [next] -1015 ---> moves to next control
How can I achieve this?

Programming / Re: ERR option ignored
« on: July 25, 2022, 01:21:13 AM »
Mike

The error is thrown by the NEW() function. The constructor as already been left, so I cannot check anything inside the object any more.

Programming / ERR option ignored
« on: July 20, 2022, 10:42:32 AM »
For a few weeks we encounter a strange error 65 every now and then, when our programs create a COM object.
Code: [Select]
ON_CREATE:
def object outlook, "[LCL]Outlook.Application", err = *next
if not(tcb(2)) then nameSpace = outlook'getNameSpace("MAPI")
return
This has been a save way ever since. On the WindX side MSG(-1) returns "Exception occured (err/ret=2/0)"
According to Eric we should check for the object reference > 0. But I wonder why the err option is ignored in these cases.

That works pretty good. Thank you.

I want to retrieve this information at runtime. SQLGetInfo sounds promising. Can you please post a sample? I can't find anything in the docs.
