I would like to ask you: how can you use VC ++ to dynamically give the value of the text box of the crystal report.

I use VC ++ to call the crystal report, and I want to dynamically set the text box value of the crystal report according to the different choices of the user. How can I set it up?

You can try the database, you can connect the value of the text box you want to the database, so that you can dynamically write the value you want in the database, and use crystal reports to connect to this database, so that you can indirectly Realize your function, this is a way to try when you have no way.
