Thank's for your help, i see your article about Crystal Report.

I'm making several testes width CR, to decide use it in my aplications.


Is possible to use a VFP Dll in Crystal Report or only VB dll's.
I try to use it, but i can´t see my function in CR.

For my teste i create a project width this code in a .prg.
I Build a Dll and put it in c:\WinNt\Crystal\CRUFLxxx.dll.

Define Class ClasseTeste as custom olepublic
Procedure MetodoTeste
Return "Geraldo F. Barbosa"
endproc
EndDefine

Before use it, i made the registration of dll like this
regsvr32 c:\WinNt\Crystal\CRUFLxxx.dll.
