An error occurred when access to the TcxTreeList object

in order to finger out the problem that caused by Test Complete or by The version of the Dev Express control. i will creat a small Delphi application with the same version of this control and with debug info to try something like before done. i will post the result to all then i get something from this practice. 

Hi All,



this problem has been resolved. l post my solution here maybe can help you all at sometimes.



1.at the beginning of i encounter this problem. i doubt that the version Dev Express control are not supported by Test Complete. we used the v2013 but TC supported latest version to v2011 vol 2.5. so development team downupgrade it to v2011 vol 2.5. then it still cannot recognized by Test Complete normally.

2.based on above step. i made a small delphi application with same control. found that it works well by TC.

3. find out that the differences betweed this samll app with the Test system is even used the same version of the Delphi xe2 IDE.but the test system used Delphi xe2 was auto upgrade from Delphi 2009, and the small app was built from Delphi xe2 directly.

continuted................

4.in order to  resure that all dev express control can be recognized by TC in Delphi xe2, we built the other small test app with the same control and test it . it works well in Test Complete.

5.Rebuild the test system with Delphi xe2. it's works well too.



besides this, i think like this problem also need to notice some delphi application was compiled with debug info but used commonline to compile it. sometimes. it will not work with Test Complete. it should to be compiled in IDE.



at the end,Thanks Tanya for help and suggestion on this.

and got this error using wChildview property while ineract the tcxTreeList objects.

the version of tc is: 9.31

yes, the third control is Developer Express Controls.QuantumTreeList and it's version i am not sure. do you think that related to the version of the Control?

Hi Tanya,



thank you replay!

given your expericenes on this, waht's the most possible reason caused that error? i think the most possible is the debug info not compiled into the application or compiled incorrect ,the developement just told me that compiled application with debug info. i have no way to check it's ture or not. ijust know i cannot get access to that object correct like others.

hi,



the problem still not resolved even through i have downupgraded the version of the Dev Express to DevExpress 2011 vol 2.5. then i compiled application with debug info. but i get the "Missing Debug Info" error then i recording script from dev control object.



any help will be greatly appreciate.
