>>I really messed up my project. I have 2 copy of the same class library in 2 different folders. Accidently, I have added objects into my form, from both classes (which I should not have done. I was suppose to only use 1 of the class library). I think this is why when I compiled my codes, the application does not run at all. It gives me a 'class name is invalid' error. I've checked my objects (in my form class) & have found some objects has the wrong parent class (class name is the same, but it is from a different folder). I've tried looking into the class browser, & there I can check parent classes of my objects, but I don't know if I can just change the parent class to the correct pathname (file name of the classlib is the same). Can anybody help???? Thank you all!!!

Another solution, which has the same effect as the solution above, but does not require you to rename or move any directories, is to USE the SCX file for your form, locate the records pertaining to the "wrong" class library (see CLASSLOC field) and change the references to the "correct" library. Close the SCX file and your good to go. In the interest of tidiness you'll still need to remove the library from your project if you are no longer using it elsewhere in another form, etc.
