Error C2664 Please Help...

[ektan]

Hi All,
I'm newbies in Visual C++ 2008 and having an error during build my code. I was unable to fix it and looking expert to help me to fix this error. My code as below:

private: System::Void button4_Click(System::Object^ sender, System::EventArgs^ e) {
const char *stop = "prog 15";
stop = "Changed";
this->label5->Text=stop;

Thanks.

this->label5 = L"Changed";
