Could you please help me create an Activex Control that is invisible at runtime
I have selected the invisible at run time option which results in

DECLARE_OLEMISC_STATUS(OLEMISC_RECOMPOSEONRESIZE |
OLEMISC_INVISIBLEATRUNTIME |
OLEMISC_CANTLINKINSIDE |
OLEMISC_INSIDEOUT |
OLEMISC_ACTIVATEWHENVISIBLE |
OLEMISC_SETCLIENTSITEFIRST

the above flags being set, I have not modified the ondraw function
the activex functions correctly but is allways visible at run time

I followed Calvins instructions to create an activex control
http://blogs.msdn.com/calvin_hsia/archive/2006/08/28/729165.aspx
the difference being that I need the control to be visible at design time
and invisible at run time.

The reason I have chosen a control and not a simple object is because it
must be loaded by the Wonderware View product.

If I create the control with MFC Framework then the visibility problem is
solved
however I wish to create it using the ATL framework for other reasons.

I can send an example project, but a new object created with microsofts wizard
and executed with microsofts test activex application will exhibit the
problem.

I have had email conversations with the engineer Peter Huang regarding this
problem

best wishes Nick.

This seems to be a product issue. Sometimes the %OLEMISC% constant is
unable to be written successfully to the reigistry.

I suggest you can try to change MiscStatus entry in your ATL control
project's reg-script (.rgs file) manually:

..
'MiscStatus' = s '0'
{
'1' = s '132497'
}
..

Thanks!

Hi Nick,

By the way, your invisible ATL control should be based on an existed
control(when you created in the New ATL Control wizard), such as a Button.

Thanks!

Hi Nick,

Thanks for the response!

I am glad to know my suggestion helps.

The .rgs file is created by the ATL object wizard, I suggest you can refer
to the following MSND documentation for its detailed format:

Registry Scripting Examples
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/_at
l_registry_scripting_examples.asp

Understanding Backus Nauer Form (BNF) Syntax
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/_at
l_understanding_backus_nauer_form_.28.bnf.29_.syntax.asp

>but am not sure how an .rgs file could create keys with multiple
>values that are needed (Value 1) do I use the val keyword.

yes, you can use the "val" keyword to specify a non-default value to a
registry key. There is a similar sample in my first reference link.

Thanks!
