使用MyDACDatabase的FastReport程序不起作用

Question

I'm using the MyDACDatabase components to connect my report build with FastReport 4 to my MySQL database. I can edit it normally and test in the FastReport designer when using my Delphi's IDE, even compile the application, but when I open the form that have the report, I have the exception Class not found: TFrxMyDACDatabase not found . How can I fix this error?

Answer 1

只是让其他人想知道，我所做的同样的问题发生在我身上，但是更改了库路径以包含FR5的位置，并再次将frxmyDACComponents添加到了使用列表中。

Answer 2

You should install FastReport X MyDAC Components from MyDAC 5 to be able to use the TfrxMYDACDatabase component. For more information please read the ReadMe.txt file in the %MyDAC%\\Demos\\Win32\\ThirdParty\\FastReport\\FRX\\ directory. %MyDAC% is the MyDAC installation path on your computer, X is the version of the Fast Report components that you use.

(Quoting from Something change in version 5 for tfrxMyDacDatabase (Version 4 no problem) )

Answer 3

The solution is very simple. I realised that in the FastReport 4 's tab I have a component named frxMyDACComponents in the pallete that I installed following the instructions in the MyDAC's Demos folder (in my case, placed into C:\\Users\\Public\\Documents\\Devart\\MyDAC for Delphi 7\\Demos\\ThirdParty\\FastReport\\FR4\\ReadMe.txt ). When I placed this component in my form, 2 units were declared in the uses clause: frxDACComponents and frxMYDACComponents . Just that was needed to this problem. Thanks for the help of everyone.
