Hi,

I am trying to keep boxes contained within one of a set of containers but with erratic results. (v4.4)
hosted in web page with vbscript.

1) I am using drag drop from one fcx document to another by using DragDropMode = drProgrControlVB

This works succesfully to drag drop a box into a container but also allows me to drop in the document even though I have a handler as follows:

Public Sub WorkArea_DragOverDocVB(ByVal dataObj, ByVal docX, ByVal docY, ByVal keyState, byref effect)
       effect = vbDropEffectNone
End Sub

I do not get the not allowed icon and the rop succeeds.

2) I respond to the event ObjectDroppedInBox and am able to move the box from one container to another and resize it to fit but cannot stop it from being dropped into the document body.

3) I respond to the event BoxModifying and even though I can see that the box is being resized bigger than the container, I cannot resize it programmatically from within the event handler. Setting Confirm = False also has no effect.

Do you have any ideas on this?

Thanks
John

Hi Iva,

Your reply reminded me of a problem I had before with creating ActiveX controls for embedding in web pages, so I whipped one together in VB and found the following.

1) VBScript does not support type declarations e.g. integer, string, boolean etc.

2) For byref parameters to work in event handlers in vbscript, they have to be declared as type variant in the ActiveX control that raises the event.

e.g. 1 (This does not work)

Sub DoSomething()
   dim Cancel as boolean

   RaiseEvent SomeEvent(Cancel)
   if Cancel then
     ---
   else
     ---
   end if
end sub

e.g. 2 (This does work)
Sub DoSomething()
   dim Cancel as variant

   RaiseEvent SomeEvent(Cancel)
   if cbool(Cancel) then
     ---
   else
     ---
   end if
end sub


3) I know that FlowChartX is written in C++, but chances are that the same logic applies.

4) Hopefully there is a better way of handling this without having to change the FlowChart ActiveX control, so I will keep looking for another solution.

5) The worst case may be for me to embed the flowchart object into a custom control and create my own event handlers with variant parameters. I will just need the licencing implications from you to do this.

Thanks and regards
John

I consulted our senior developers and they said that embedding FlowChartX in a custom ActiveX control is a very good solution if you don't want to modify the control.
