Hello all, I'm writing a simple app for the device that will let you save and restore all your contacts and calendar events. I'm using wm5 and netcf 2 and basic4ppc v6.3. I've encountered several problems I can't seem to figure out. It is related to my use of outlook.dll. The optimized force qvga compilation gives the following error at runtime. The non optimized compilation gives the following error. The regular optimized compilation will run but then gives me the later of the two errors from time to time in the following code. Code: For i = 0 To PCol_contacts.Count-1 PCol_contacts.RemoveItem(i) label1.Text="Contact "&i&" removed" Next Msgbox("Removed all Contacts") If I have 400 contacts it will produce an error after deleting 200, if I press yes to continue, then the error pops up after deleting 100, then at 50, then at 25, and so on. Very strange. I encountered the following problem http://www.basic4ppc.com/forum/questions-help-needed/2297-problem-contacts.html#post12428 but I don't think it's related because for now I'm just ignoring the webpage field. Any ideas?
