HOW TO: Use the Windows Operating System Controls

I can't use the Framework Controls as I wish
Is there a simple and fast way to use the Windows Operating System
Controls instead?

Windows Forms controls /are/ Windows "operating system" controls.

Because they are not well behaved controls

I am sorry to disagree, the Framework Windows Forms Controls act as
inherited controls.
For instance, you can't use the Operating System SendMessage to Set the
Items from a List Control (ListBox or ComboBox) and then use the
Items(i) to retrieve them.

I am looking for something like Forms 2.0 controls that seem to agree
with the Operating System. I believe that Forms 2.0 controls can't be
distributed with a VB application.

Do have any URL about this? Even if it is for C++?
 
John,

Yes, but internally, they are based on the Win32 controls.

That's maybe a synchronization problem between the operating system's
management of the control and the .NET wrapper.

Forms 2.0 were /not/ operating system controls and they must not be
distributed.

Have a look for 'CreateWindowEx', the 'NativeWindow' class, etc., in
MSDN, but I don't think this will make you lucky.

I think you are right about it.
Developing controls from 'scratch' takes a long time.

Tnaks anyway

What exactly do you want to do, why do you need p/invoke? Maybe there
is a better solution...

I want to enhace simple functionalities like the full word search for a
listbox (you type part of a word and it becomes selected)

Want to use the ItemData for any List Control

Want to be able to avoid Text Change in a ComboBox when you drop it down.

I already implemented partially those functionalities but there is
allways something missing.
