call Func1 until all data is loaded, then call Func2 to handle them .... Does this mean that, I am trying to access the data before it is loaded? I am not sure what we mean "Data loaded" here. This may sound primitive question. But I will appreciate further explanation. Thanks and regards, Shrinivas

Hi all, I need to pass large data( in the order of MBs ) to DLL for processing. When I pass a reference to such object that holds reference to this data from the application and then, trying to access the member variables from passed object causes crash my application. Note that, it works fine if 1. I downsize data in object, 2. I make member variables public. Is there any thing special I need to do when passing and processing large data to DLL? Hope I am clear about the question. Please feel free to ask any questions, that would help to understand problem more correctly. Thanks and regards, Shrinivas
