<p style="margin-bottom: 12pt;">Hi,<br>
<br>
Is it possible to call a method of a class without creating a object of it,
even if the method is not a class function in Delphi ? I wrote the below code
just to test -<br>
<br>
1. Created a simple form A and a button on it. <br>
2. Created another simple form B, written a procedure in it as -<br>
FormB.Execute;<br>
begin<br>
ShowMessage("xyz");<br>
end;<br>
3. Commented out auto creation of FormB in application.<br>
4. On Button Click in FormA I called the Execute of FormB and it worked
perfectly okay. <br>
<br>
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.<br>
<br>
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. <br>
<br>
May be I am missing something simple here, but any pointers will be great. This
was done in D2005 and it's win32 app.<br>
<br>
Thanks<br>
-Ani</p></span></div>
