>Thank you very much. It solved the mistery. But since that we remove the source method of the class by using the replace command how still execute the same method? But thank you your answer work well.

Because even though your are executing a 'method' of the class, the code executing is not in the vcx.method memo field. That memo (method) is just the clear text vfp holding area. When you run a vcx, the VFP engine is reading the compiled object code in the vcx.objcode memo field. This is why you can change your original vcx.method code with your editor, and realise the changes have not occurred - probably because you did not have the 'compile when saved' option set by default (although most developers do).
