Just guessing, but the fact that he wants to dynamically create them at runtime by "name" rather than explicit TButton.create implies a dynamic nature of design where the classes wont be <br>known at design time.. ie Form Builder.<br>

Are there reasons you would avoid making the objects at development time as<br>
not visible and making them visible only when needed?<br>
Stated without negatives, make the objects now, make them invisible and when<br>
needed make them visible.<br>

Subject: [DUG] Creating an object at run time.<br>
<br>
I want to create an object at runtime given a string with the object type.<br>
Is this possible or do I need to do a whole pile of if then else's? There is<br>
a limited number of different objects that need to be created. I then want<br>
to access the created objects properties by name and assign methods.<br>
<br>
This is not for oleobjects, but VCL controls.<br>
<br>
i.e.<br>
b := CreateObject('TButton') ;<br>
b.GetField('left') := 100 ;<br>
...<br>
<br>
Help on any of these would be appreciated.<br>
<br>
Cheers,<br>
Dave.<br>
