Hi Stoyo,

1- I created a process flow in a FCX document then i want to take this process flow as a whole and insert it in a new FCX document as a single group, so how can this be done?

2- If i want to move this process flow within the same document as one unit, for example moving it to the center of a page or to its left edge, is there any way to do this programatically? i tried to use SetRect or MoveTo for each box, but the process flow is then ruined as the perpendicular arrows are elongated and have new points above the process flow.

Thanks in Advance

Hi Andrew,

1. You could use a bsContainer box or a bsAxControl box hosting a Flowchart instance to contain the process flow. If using a hosted flowchart, you can load the flow document simply by calling LoadFromString or LoadFromFile. If using containers, call fc1.SaveToStream() and fc2.LoadFromStream() to transfer the items to the second flowchart without clearing its existing elements. After LoadFromStream, you can loop over SelectedBoxes and call their PutInContainer  method. You should also set the container's LayoutStyle to lsCustom to preserve the box positions.

2. If you use any of the above methods, you can set only the container's position and the children will move too. Otherwise you will have to loop over the arrow points and offset them via the CtrlPtX/Y properties.

I hope that helps,
Stoyan

1) Can you give me an example for using the SaveToStream and  LoadFromStream methods as i usually receive an error.

2) How can i decide the coordinates of the loaded boxes (LoadFromStream) or the Pasted ones (PasteFromClipboard).

Thanks in advance

1. You can create a memory stream via the CreateStreamOnHGlobal API function, e.g. in VB6:

Code
Select All
Private Declare Function CreateStreamOnHGlobal Lib "ole32" (ByVal hGlobal As Long, ByVal fDeleteOnRelease As Long, ppstm As Any) As Long

Dim memStreamDisp As Object
CreateStreamOnHGlobal 0, 1, memStreamDisp

Dim memStream As olelib.IStream
fcx.SaveToStream memStreamDisp
Set memStream = memStreamDisp
memStream.Seek 0, 0
fcx.LoadFromStream memStreamDisp


olelib.IStream is from the first type-library by Eduardo Morcillo on this page:
http://www.mvps.org/emorcillo/en/code/vb6/index.shtml

2. If you need to offset the items after pasting them, you can do that by iterating the selection lists and call MoveTo for boxes and set CtrlPtX/Y for arrows. The following seems to work, but I haven't tried it for all types of arrow property combinations:

Code
Select All
Sub MoveAllSelected(dx As Integer, dy As Integer)
	Dim b As box
	Dim t As table
	Dim a As arrow

	For Each a In fcx.SelectedArrows
		For i = 1 To a.CtrlPtCount - 2
			a.CtrlPtX(i) = a.CtrlPtX(i) + dx
			a.CtrlPtY(i) = a.CtrlPtY(i) + dy
			a.Update
		Next i
	Next a

	For Each b In fcx.SelectedBoxes
		b.MoveTo b.left + dx, b.top + dy
	Next b

	For Each t In fcx.SelectedTables
		t.MoveTo t.left + dx, t.top + dy
	Next t

End Sub


I hope that helps,
Stoyan
