And here is code , which won''t work, i tried to transfer from Private only to txt first then i would copy code for the rest..

//code sample
			 String^ s1;
			 String^ s2;
			 String^ s3;
			 int n;
			 n = treeView1->TopNode->Nodes[0]->Nodes->Count;
			 int m;
			 m = treeView1->TopNode->Nodes[1]->Nodes->Count;
			 int z;
			 z = treeView1->TopNode->Nodes[2]->Nodes->Count;
			 //upisujemo
			 StreamWriter^ sw = gcnew StreamWriter("view.txt");
			 sw->WriteLine("class " + treeView1->TopNode->Text + " {");
			 for(int i  = 0; i<n; i++)
			 {
				 sw->WriteLine(treeView1->TopNode->Nodes[0]->Text);
				 sw->WriteLine(treeView1->Nodes[1]->Nodes[i]->Text);	
			 }
			 
			 sw->Flush();
			 sw->Close();
			 delete sw;
