well the error i get is the title above:
error C2664: 'searchTree' : cannot convert parameter 2 from 'const char *' to 'char'

error is form this line

Expand|Select|Wrap|Line Numbers

searchTree(treeObj->root ,data1.c_str());

i have also attached searchTree below for yr reference

Expand|Select|Wrap|Line Numbers

 
Tree<char> *treeObj = NULL;

TreeNode<char> *treeNodeObj = NULL;
 
TreeNode<char>* searchTree(TreeNode<char> *cur, char nodeToAdd)

{

    if(cur == NULL) 

    {

        return NULL;

    }

    if(cur->IsSameNode(nodeToAdd))

    {

        return cur;

    }

    searchTree(cur->getLeft(), nodeToAdd);

    searchTree(cur->getRight(), nodeToAdd);

}

could anyone help me with this problem..?
well at first i get the problem that it can convert from char to string.. thats y i added the .c_str() but now it gives me the new error above..
any help is appreciated..
I will check forum every 5 mins .. so i will reply quick..

what is 'data1' ? How did you declare it?

other than that, it LOOKS like you are attempting to make 'data1' into a string, and then pass it into a function looking for a char ... that's just not gonna happen ... why are you passing some sort of string into a char argument?

oops my bad..
i declared it as string..

Expand|Select|Wrap|Line Numbers

 
void handleOneLine(string string1)

{

    char * cstr, *p;

    int counter;

    string str (string1);

    string data1, data2, data3;
 
    cstr = new char [str.size()+1];

    strcpy (cstr, str.c_str());
 
    // cstr now contains a c-string copy of str
 
    int count = 0;

    p=strtok (cstr,",");

    count++;

    while (p!=NULL)

    {

        p=strtok(NULL,",");

        if( count == 1 )

        {            

            data1.append(p);

            searchTree(treeObj->root ,data1.c_str());

        }

        else if( count == 2 )

        {

            data2.append(p);

//            treeNodeObj->setLeft(data2);

        }

        else if( count == 3 )

        {

            data3.append(p);

//            treeNodeObj->setRight(data3);

        }

        count++;

        if( count == 3 )

            break;

    }
 
    delete[] cstr; 

}

I edited my previous post, not sure if you saw ...

it looks like you are attempting to make 'data1' into a string, and then pass it into a function looking for a char ... that's just not gonna happen ... why are you passing some sort of string into a char argument?
