How to: empty page file / virtual memory once and a while ?

[TakisTakis]

Hi,

I have noticed that the after every historic backtesting the amount of hard disk that has been used for testing increases. This means that if a certain backtesting increases the page file - virtual memory by lets say 100k, if I do the same test three times the disk will have increased by 300k. This makes computer slow, computer doesnt like that . I presume that this happens so that we can access older backtesting simulation that we did since we turned the application on. However, once I do another test, I can no longer access the results from any previous test other than the last one. Nevertheless, NT7 still retains that space on the disk.

Two questions:
- IMPORTANT: Is there a way to liberate that page file either through some option or through some programming order, other than having to restart the entire NT application after each time ?
- (not so important) As I see that the computer holds the data, is there anyway to access them ? Right now I can only access the latest simulation data only.

TakisTakis, this is unfortunately all controlled by the .NET framework garbage collection, so once objects / resources are released the cleanup would be handled automatically.

If you use any custom resources, please ensure to dispose them properly in OnTermination() -
