But in case if your file related classes do not help, why don't u keep a boolean variable and set it when u open the file. U can then enable/disable the menu depending on the boolean value. For ex. like the following.     if(x == 0)         pCmdUI->Enable(TRUE);     else         pCmdUI->Enable(FALSE); If ur problem is just checking the status of the file, can u share the class u r using the for the file operations? Also just paste the code snippet u r using.. HTH Muthu    Report
