Discussing coding style of non-fixed length Multi-dimension Array

[cylix2000]

I have a number of experience on using 2 dimension array in VB.NET, I would like to know some better, and standard pattern to write it. for an example, We need to pass a set of patient record from a modules to a form, this record include all the current male patients(no fixed length). the record includes (name, sex, age) Please give me advise and write down your coding style in this issue. Thanks!!

I wouldn't use arrays at all. Make a class with the properties for a patient. Create objects from the class and put the objects in a list, for an example an ArrayList. --- b { font-weight: normal; }

I'll second the other reply and extend it a bit. 1) Create a Patient Class including all the attributes for the patient (name, gender, age, et al.) 2) Create a PatientCollection class, inheriting from CollectionBase (see Walkthroughs in help for details on how to do this) The Patient class is a gimme. It is pretty much a canonical example of a class/object to be used in a program. The PatientCollection is a bit more work than the ArrayList but is safer and since you have Option Strict turned on (hint, hint) it will save some casting in your code. hth Alan.
