How to compare CString and CArray?

**ooosawaddee3** · 10-14-2002

I declare these below data

Code:

CString Hash[2] = {"208803DD4D","146DB1CB1C"};
CArray<unsigned char, unsigned char> hashdata;

and hashdata have some value
I compare CArray and CString like these

Code:

if (hashdata == Hash[0])
	{
	......
                .....
                .....	
}

but there is error message show

error C2678: binary '==' : no operator defined which takes a left-hand operand of type 'const class CArray<unsigned char,unsigned char>' (or there is no acceptable conversion)

Do I need to change CArray to other type of data? If you know how to solve my problem, please tell me.
Thank you very much.

have not used CArray but I have used CList and CMap and I know they are similar. You can't compare against the entire array you must compare against it's elements. You need to iterate thru the array and compare each element until you find the one you want. There is sample code on the msdn website for how to itrate thru the members.

Code:

CArray<CPerson*, CPerson*> myArray;

int i=0;
while (i < myArray.GetSize() )
{
    if( myArray.GetAt( i++ ) == myvar )
       domycode();
}
