Topic: Callback procedure problem
Conf: (P-PDF) Developers, Msg: 34558

Hy, thank for previous help about callback procedure.
I'm sure that with the callback I use a text is extracted from my PDF document : with an AlertNote I can display it on my screen during the executiion.
My problem is that when I try to get it into an array of char*, for example, running in a FOR statement, the extracted text is added to the same string, instead of the string of the next cell of the array :


typedef struct enregistrement{
char * extraction;
} Tenreg, *Penreg;
...

//my callback
ACCB1 void ACCB2 PDTextSelectEnumTextProc2 (void* procObj,PDFont font, ASFixed size, PDColorValue color, char* text,ASInt32 textLen){
Penreg data = (Penreg)procObj ;
// add a separator and the text
strcat(counting->extraction,"#");
strcat(counting->extraction,text);
}
...


//Main

...
Tenreg * extract = new Tenreg[numberOfPages];
for (i=0;i<5;++i){
PDTextSelectEnumText ( selection,
ASCallbackCreateProto(PDTextSelectEnumTextProc,
PDTextSelectEnumTextProc2),
&extract[i]);
ASCallbackDestroy(PDTextSelectEnumTextProc2);
AVAlertNote (extract[i].extraction) ;
}



More over, if I add other AlertNotes, with constant string in, in the main, instead of these constant strings, there are parts of the selected text.
It's very inconfortable.

Can someone help ?
