Hello.

I have two laptops in my home. They have Win7. I want to connect them with cable but after plugging in, Network and Sharing Center says that the network is unidentified. In fact, when I run troubleshoot, the problem is detected as "Local Area Connection doesn't have a valid IP". I already turned on file sharing. Please Help me.

Thanks.NTY3

I want to upgrade my Vista to Windows 7. After checking compatibility, a window appears and says that "GoogleToolbar" should be uninstall. But in "Control Panel > Programs and Features" there is not any program called GoogleToolbar. I also checked "Program Files" in drive C: and deleted googletoolbar folder. But the problem still exists. How can I uninstall that?

Thanks.

I have installed windows 7 on my "Hi-Grade" laptop that has windows XP as default operation system. But now I have problem with my computer's resolution.

What can I do?

Thanks.

Hi,

I have a problem with searching in a tree structure data in C++. My code is below. Every node in the tree has 3 children. My 'search' function is recursive and I want to specify that is there any node in the tree that has my 'item' or not. But 'search' does not work.

class tree{

char* key;

tree* left;

tree* mid;

tree* right;

public:

bool search(tree *temp, char *item) //temp is root of tree

{

if (temp == NULL)

return false;

if (item == temp->key)

return true;

if(search( temp->left,item )) return true;

else if(search( temp->mid,item )) return true;

else if(search( temp->right,item )) return true;

else return false;

}

}

I need to save 'name' and 'student number' as string and 'score' as a double. So I defined two 'string' and a 'double'.

But this problem exists: by using getline(cin,str), console does not wait me to enter 'score'. Because of using 'cin>>' after 'getline'.

What can I do?
