I recall from using RealBasic in the past that there is some AppleEvent you can execute that locates a program based on its creator code. I think there is some way to enter this into Script Editor, but I forget what the command is.
This would enable you to find any copy of IE on the users system regardless of where it is installed. In fact, the creator code is all you need to tell the program what to do, if you're trying to control IE from RR. Effectively, you don't actually know where the copy of IE is installed, and you don't need to - you can launch and control it without knowing where it is. I don't know if it is possible just to detect the presence of IE, but is possible to try the event that launches it, and if it fails, the user doesn't have it. Below is some code I used in RealBasic to launch Graphic Converter if it isn't already running. One issue is that once you launch an app with an AppleEvent, if you try to tell the app to do something before it has finished launching, the event will fail. Unfortunately, there is no event to find out if the app has finished launching. What my code does is wait for GraphicConverter to launch by trying an AppleEvent that reports how many windows GraphicConverter has open. This event will fail unless GraphicConverter is finished loading an has displayed its UI. So the program simply continuously tries executing the AppleEvent until it is successful. IE should support the same event for how many windows are open, so the idea shd work. You would need to adapt this code for RR (I just started using RR yesterday, so I have no idea how it supports AppleEvents). This code is fairly low-level, in RealBasic you have to specify the event type and class and creator, so it may be hard to follow. ======================================== 'Wait for Finder to launch GC ae = NewAppleEvent("aevt", "odoc", "MACS") obj = GetUniqueIDObjectDescriptor("appf", nil, "GKON") ae.ObjectSpecifierParam("----") = obj if not ae.Send then MsgBox "GraphicConverter is not available." Quit end if 'Wait until GC is able to report how many windows it has 'That way, we know it's ready for events ae = NewAppleEvent("core", "getd", "GKON") obj = GetOrdinalObjectDescriptor("cwin", nil, "all ") ae.ObjectSpecifierParam("----") = obj while (not ae.Send) wend 'Bring myself to front. ae = NewAppleEvent("aevt", "odoc", "MACS") if DebugBuild then obj = GetUniqueIDObjectDescriptor("appf", nil, "RBv2") else obj = GetUniqueIDObjectDescriptor("appf", nil, "Bant") end if ae.ObjectSpecifierParam("----") = obj if not ae.Send then MsgBox "Unable to activate self." end if ======================================== > Can anyone tell me if there's a way to detect on Mac OS X if IE is > installed, > via Revolution?
