Two dimension array cannot be created like this. You have to do like

    CString** pStr = new CString* [10];
    for( int i = 0; i < 10; i++ )
        pStr[i] = new CString[10];

Sorry: use a CString* is legal but you ar right using a CStringArray is best practice :->

While you probably should use an array class as others have mentioned, you can create multi dimension arrays on the heap if you use the proper syntax: CString (*mydata)[10] = new CString[10][10]; ... delete[] mydata;

In that case I don't see why you need a multi-dimension array. Directory listings are one-dimensional. A CStringArray is an excellent choice IMO. Mark

I CStringArray is enough for the purpose.

May you are not calling delete in the proper way.
