我有Midas项目,在服务器的RemoteDataModules之一中使用TDataSetProvider
目前我正在利用以下事件
题:
即使是更新错误,也会始终调用'AfterApplyUpdates'吗?

如果你看一下源代码:
function TCustomProvider.DoApplyUpdates(const Delta: OleVariant; MaxErrors: Integer;
out ErrorCount: Integer; var OwnerData: OleVariant): OleVariant;
begin
SetActiveUpdateException(nil);
try
try
if Assigned(FOnValidate) then
FOnValidate(Delta);
DoBeforeApplyUpdates(OwnerData);
Self.OwnerData := OwnerData;
try
Result := InternalApplyUpdates(Delta, MaxErrors, ErrorCount);
finally
OwnerData := Self.OwnerData;
Self.OwnerData := unassigned;
end;
except
on E: Exception do
begin
SetActiveUpdateException(E);
raise;
end;
end;
finally
try
DoAfterApplyUpdates(OwnerData);
finally
SetActiveUpdateException(nil);
end;
end;
end;

Yoy看到在finally块中调用了DoAfterApplyUpdates.这意味着它总是被称为任何例外的问题.
