Creo que no he entendido bien tu problema:
A.- Quieres un caption con mas de 140 caracteres
B.- Controlar que el caption no tengas mas de 140 caracteres
Yo habia entendido la opcion B
Tengo un gran problema con el idioma ingles
Enrico
I think I misunderstood your problem:
A. - You want a caption with more than 140 characters
B. - Check that the caption does not have more than 140 characters
I had understood the option B
I have a big problem with the English language

No, the problem is that there is no such limit in the size of a dialog title (Windows API docs don't mention any limits). The current limit is only the result of a bug in cDlg2Chr() function. At least this is what I understood.
Is it more clear now?

The problem is that I don't understand the code of cDlg2Chr() function very well so I found that "fix" with trial and error.

Enrico
we are filling a
DLGTEMPLATE structure, is used like argument in the function
CreateDialogIndirect...
check
DLGTEMPLATE structure remark section
In a standard template for a dialog box, the DLGTEMPLATE structure is always immediately followed by three variable-length arrays that specify the menu, class, and title for the dialog box. When the DS_SETFONT style is specified, these arrays are also followed by a 16-bit value specifying point size and another variable-length array specifying a typeface name. Each array consists of one or more 16-bit elements. The menu, class, title, and font arrays must be aligned on WORD boundaries.
...
Following the class array is a title array that specifies a null-terminated Unicode string that contains the title of the dialog box. If the first element of this array is 0x0000, the dialog box has no title and the array has no other elements.
...

Daniel,
So what? Are you trying to say that my "fix" can be correct?

Ok.
At the moment, I'm convinced that iLenUnicode doesn't have to double (*2) but I would hear your opinion.

I'm testing my fix and found no problem so far. The fix is:
replace
with
in dlg2chr.c.
