I have this piece of code:
static void Retorno(){
FieldPtr fldEntrPtr;
FormPtr form;
FormPtr previousForm = FrmGetActiveForm();
form = FrmInitForm(frmRetornoNum);
//FrmSetActiveForm(form);
FrmDrawForm(form);
FrmSetFocus(form,fldEntrada);
FrmDoDialog(form);
fldEntrPtr=FrmGetObjectPtr(form,FrmGetObjectInde(form,fldEntrada));
if(FldGetTextPtr(fldEntrPtr)){ //se string nao
vazia..
StrCopy(tempString,FldGetTextPtr(fldEntrPtr
}
FrmDeleteForm(form); //deleta o novo
form..
FrmSetActiveForm(previousForm); //torna o antigo form
o ativo
}
But I couldnt be able to do it work, it doesnt matter the
order of the APIs. Or it cracks or it doesnt put the
cursor...
