Hi, just started looking into writing a little program that detects if Media Center is playing that will be used to control on/off of an amplifier.

I'm using Delphi and the Media Center com object.

Can anybody tell me why the following code does not work:

Code: [Select]

for i := 0 to MC.GetZones.GetNumberZones do
    listbox1.Items.Append(mc.GetZones.GetZoneName(i));

Regards

Well, without knowing how you defined mc, I am assuming you successfully made the connection to mc and recieved a valid mc object.  Also, if you could tell us what the error you are recieving is, we could probably give you better information.

But, since GetZoneName is a 0 based array, you should use MC.GetNumberZones -1 as you upper limit.  If there are three zones, then they are number 0, 1, 2 and I am assuming that GetNumberZones will return a 3.

Hope this helps,

Alex

Thanks for your response

Updated code:

Code: [Select]

  mc.Connect;
  for i := 0 to MC.GetZones.GetNumberZones -1 do
    listbox1.Items.Append(mc.GetZones.GetZoneName(i));
  mc.Disconnect;

Connection works fine, and adding the name of the first zone works ok.

When trying to add the next name I however get:

First chance exception at $00C68FBB. Exception class $C0000005 with message 'access violation at 0x00c68fbb: write of address 0xb4000000'. Process Project1.exe (9168)
