Example of using ActiveX inside OpenDCL ?

Hello,

I would like to know if it's easy to use activeX inside openDCL, and if anybody already use these ???

Thanks for help.
Best regards.

Hi Stepjan, you mean an ActiveX control? It is as easy as you can trust that the user has installed it. I have used it at my ObjectDCL dialogs. But some admins did not install the controls I needed or the control was unregistered. Then error messages came up and I gave up.

Hi,
By the merest chance, would you use the ActiveX control treeview?
I'm having some trouble with setting objects OpenDCL, and I wanted to attempt the side of ActiveX ...

I found this :
{2}

(dcl_AxControl_DoMethod "Add" )

The arguments are more fully described at:
{2}

To test the tree control, I tried the following:

(setq Nodes (dcl_AxControl_GetProperty "Nodes"))
; now Nodes is an OLE Object, and we use (dcl_AxObject_*) syntax
(Setq NewNode (dcl_AxObject_DoMethod Nodes "Add"))
; NewNode is also an OLE Object
(dcl_AxObject_SetProperty NewNode "Text" "MyNewTreeItem")
; this should work, but the call into the tree control fails with a COM error
(setq text (dcl_AxObject_GetProperty Node "Text")) ;this works fine
(dcl_AxObject_Close NewNode) ;release the node
(dcl_AxObject-Close Nodes) ;release the nodes collection

I'm not sure why the call to set the 'Text' property fails, but I will investigate this. The code above should work, and at least it can demonstrate the basic steps.

Thank you for your help
Best regards
