Hi Ben,
There is no limitation on the maximum number of objects - it depends more on the PC resources than on TestComplete. I suppose that the tool does not actually hang when there are many objects on a web page. Most probably, it just takes long to build/update the object tree. First of all, try using suggestions provided in the following technical paper - they can help you improve the objects recognition speed:
Automated Test Performance TipsIf the suggestions do not help, please follow the instructions below to help us collect more information about the problem:
1. Download the Debugging Tools for Windows package from:
http://www.microsoft.com/whdc/devtools/debugging/installx86.mspxand install it.
2. When TestComplete and (or) the tested application hang(s), run two instances of WinDbg ("C:\Program Files\Debugging Tools for Windows\windbg.exe").
3. Attach the first WinDbg instance to TestComplete's process and attach the second instance to the tested application's process (File | Attach to a Process).
4. Type the following command in the Command window of the first instance of WinDbg:
.dump /m "C:\TCDump.dmp"
and press Enter.
5. Type the following command in the Command window of the second instance of WinDbg:
.dump /m "C:\AppDump.dmp"
and press Enter.
6. Click Go on the WinDbg toolbar (or press F5) in both WinDbg instances. Wait for one minute and click Break (or press "Ctrl + Break") in both instances of WinDbg.
7. Repeat steps 4 and 5 to save another set of dump files with different file names.
8. Without a delay, repeat steps 6 and 7 two more times.
9. Send us all of the dump files created in the steps above.
Thanks in advance.
