Creating Controls at Runtime

[Mauri]

Hello there, I have a form that has controls created at runtime, if I run the project using the Standalone it works fine, but when I deploy it to Apache 32bits when I try to open the form I get an exception "Control '' has no parent Window"

 

Does anyone know what might it be?

 

Thank you.

Hi,

 

Probably you are using non-uniGUI controls in your application.

If that was the case shouldn't the error occur in the standalone aswell?

In standalone we have a real vcl app in background handling message loops. In isapi or service no such loop exists

[Mauri]

In fact I created components but all of them Inherit from Unigui components, is there anything I should bear in mind when it comes to custom components? Like, events, references, etc..?

You are using controls which rely on Windows Handle and message loops. uniGUI components won't need them.

I'll check my code too see what's happening.. thank you

Solved it, the problem was not in my components, it was actually a function that I had in my legacy software that used a TLabel to get the Canvas.TextWidth to set the Width of some components, just replaced the TLabel for a TUniBitMap and it's working fine, thanks for the help.
