1. How do I start a WPF Application on startup?

Public void autoopen () {// obtain the program execution path .. string staruppath = appdomain. currentdomain. basedirectory + "hsfjqalarm.exe"; // class Micosoft. win32.registrykey. indicates the entry-level node in the Window registry. This class is installed in the registry. registrykey loca = registry. localmachine; registrykey run = loca. createsubkey (@ "SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run"); try {// setvalue: name of the stored value run. setvalue ("David", staruppath); loca. close ();} catch (exception ex) {MessageBox. show ("error message:" + ex. message );}}
