// Function: IsAnotherComponentRunning32()
//
// Synopsis: Checks if there's another ICW component already
// running. If so, it will set focus to that component's window.
//
// This functionality is needed by all of our .exe's. However,
// the actual components to check for differ between .exe's.
// The comment COMPONENT SPECIFIC designates lines of code
// that vary between components' source code.
//
// For ICWCONN1, we return FALSE if the following are already running:
// another instance of ICWCONN1, any other component
//
// Arguments: bCreatedSemaphore --
// -- if TRUE, then this component has successfully created
// it's semaphore, and we want to check whether other
// components are running
// -- if FALSE, then this component could not create
// it's semaphore, and we want to find the already
// running instance of this component
//
// Returns: TRUE if another component is already running
// FALSE otherwise
//

// in icwconn1\connmain.cpp
