Asking our great god can speak some Delphi version compatibility, such as 2010 to xe6, thank you ~

CodePudding user response:

Delphi version, can be divided into three big step: Delphi7 Delphi2010 EX, the difference is:

1, grammatical, improved,
2, the new version of the original method, modified,
3, some new methods,
4, new controls, individual original control no longer supported,
5, the progress of technology, such as DataSnap in D7 USES is Com technology, and adopted new techniques in XE,

Overall, the low version of the code, on the high version, change is not big, you can run, on the other hand, is more difficult,

Kind of third party controls to backward compatibility is not

CodePudding user response:

Regarding to the application of controls, basically so small, but, just the three control installation must be able to apply to Delphi version, otherwise can't install,
