Excuse me, ladies and gentlemen: a relatively large program (10 to PBL, also call each other between the PBL, lots of inheritance, calls the Windows API functions,), want to upgrade from 8.0 to 12.5,
In what order to upgrade?

CodePudding user response:

Upgrade the whole application directly, cannot PBL upgrade one by one, otherwise will be a lot of mistake

To upgrade the whole application, also will go wrong, according to the error message again modification, but some should be program calculation results could be different, such as len (" China ")

The return value is 4 in pb8, in pb12.5 is 2, after l level, to test the process,

CodePudding user response:

This upgrade can take several hours to ten hours,

8.0 to 12.5, I need to change a lot of places

CodePudding user response:

Open the project, with pb12.5 litres, however, the estimation problem is more, a test people's patience, involving the character set function, must be rewritten, such as: len, calculation of the length of the string may need to fine tune the external dynamic library function,

CodePudding user response:

To adjust more

CodePudding user response:

From pb7 an upgrade to pb12,
Use pb12 new project, increasing the global variables such as
Then add PBL, migration code
Just then handle errors.

Takes a few days is the basic of

CodePudding user response:

With PB12.5 directly to open, then the upgrade, then must pay attention to the len (), mid (), left (), right () function, into the PB12.5 should use lenA behind () in the same way, the more troublesome time-consuming
