I am reading the name of an application from a registry value, however I need to change the code to read multiple application names from the registry value.  The registry value will be a comme delimeted string, and I think I need to read these values into an array and then launch these application.

As I have virtually no C experience, can someone please help me with this ?
success = get_registry_value(APPLICATION, "WorkstationRole", newApplication, sizeof newApplication);
	
if (success)
{	
	sprintf (WorkstationRole, "%s%s", path, newApplication);
 
	if(CreateProcess(NULL,
		WorkstationRole, // cmd line
		NULL, // process sa
		NULL, // thread sa
		FALSE, // inherit handles
		0, // flags
		NULL, // env
		NULL, // cur dir
		&sui,
		&pi))
{
// Close the thread handle as it is not required
CloseHandle(pi.hThread);

Assuming that newApplication is a char*, you can use strtok to split it up into tokens :

        http://www.cplusplus.com/reference/clibrary/cstring/strtok.html

char *newApplication;
 
char *token = strtok(newApplication, ",");
while (token) {
  /* use token here */
  token = strtok(NULL, ",");
}

appname = strtok (newApplication, "," );
while (appname)
{
     //create process goes here ... appname has application name
     appname = strtok (NULL, "," );
}

May I ask what made you accept sunnycoder's response, and not mine ? It seems that we posted the same exact answer at the same time, so shared credit seems in order ... Or am I missing something ?
