Yes, I got confused too and bit surprised to see why Delphi allowed me to do this :)

Yes you can do this. In this case the Self pointer is nil, and any reference to any property on the from B will give a AV, but if no references to class instance properties, then in effect you have a class function. Is not very good programming. Does not really make sense unless you want to confuse someone!

I wrote the below code just to test - 1. Created a simple form A and a button on it. 2. Created another simple form B, written a procedure in it as - FormB.Execute; begin ShowMessage("xyz"); end; 3. Commented out auto creation of FormB in application. 4. On Button Click in FormA I called the Execute of FormB and it worked perfectly okay. What could be the reason for this? I had the idea that either I need to create an object before calling any method or I need to declare a class function. In the above steps when I am trying to call Show in Execute function of Form B I got Access violation which is perfectly fine according to the above statement. May be I am missing something simple here, but any pointers will be great. This was done in D2005 and it's win32 app. Thanks -Ani Attention: This communication is confidential and may be legally privileged.
