yes.through the debugger,the field object is locked only twice.and the error
i'm getting is a run time error.ie,i'm getting the error only when i try to
write something into the field AND NOT OTHERWISE.anyway,her's what i'm
doing.
if(l_numofrecords<2)//this is to check locking,the variable increases
to 3
and no locking takes place later,it
skips the next line
MemHandleLock( g_recordH );
g_record = ( HelpDBType* )( g_recordH );
if (g_record == NULL)
return dmErrIndexOutOfRange;
l_fldP =( FieldType* )
mGetObjectPtr( l_frmP,FrmGetObjectIndex( l_frmP,
myfield1));
l_fieldH= FldGetTextHandle ( l_fldP );
l_fieldH=g_recordH;
FldSetText ( l_fldP,l_fieldH,0,sizeof((g_record->formid)));
FldDrawField ( l_fldP );
///i'm doing the same for the next field as well,ie, MYFIELD2 //
the following code goes in my form handle event when i exit from the form
through a button
l_frmP = FrmGetActiveForm();
FieldType* l_fldP,*l_fldPP;
l_fldP =( FieldType* )
FrmGetObjectPtr(l_frmP,FrmGetObjectIndex( l_frmP,
myfield1 ));
FldSetText ( l_fldP,NULL,0,sizeof(g_record->formid) );
//and of course the same for MYFIELD2.//

Subject: Re: field overlocking?!!!
I need to see some code here. Have you tried running your program through a
profiler and see how many times the field's handle _actually_ is locked
without begin unlocked?
