EncodeAndSend is not a static function  which means it can be called on an instance of the class CPMSifDlg  You cannot write this    CPMSifDlg  EncodeAndSend              wrong - EncodeAndSend is not static   It should rather be called as    CPMSifDlg dlg    create instance  assuming it has default constructor   dlg EncodeAndSend               correct

Only static functions are called with class name    classname  Staicfunction      Non static functions have to be called using objects    classname obj  obj Somefunction      This is exactly what your error means  Since your function is non static you have to use a object reference to invoke it
