int value through string

[eranga262154]

Hi all,

I have a string(not a CString), actually a file path. As an example,

c:\Test\MyProject\G00062_002_01.srf

Then in following way get some data.

string FullPath = c:\Test\MyProject\G00062_002_01.srf
string filePath = FullPath.GetFileTitle();

		string groupID;		
		string sessionId;	
		string partID;		

		groupID = filePath.substr(1, 5);
		sessionId = filePath.substr(7, 3);
		partID = filePath.substr(11, 2);

So my outputs are 00062, 002, 01 respectively as string type. I want to add those values in a database as int type. How should I do this conversion.

Where I'm confusing is that, outputs are in string format. But actually there are some integers.
