Hi

i am working with Addflow control and i have few problems/Questions using this control

Question 1

I have a property used in VB called LastUserAction.
Can i know the equivalent of this using in .net

Question 2

In VB Addflow Constants(afLinkStretching,afLinkCreation...etc) from AddFlow.Lib are used. How do we use this in .Net or any equivalent of this?

Position in AddFlow control on mousedown sseverson [USA] 22-Sep-2004 23:33:07

I have noticed that the x and y values for the position of the mouse click in the mousedown event gives the relative position, not the position in the event you have scrolled. Is there a way to get either the scroll amount or the absolute position (lik the top and left properties of a node) in the addflow control?

Sincerely,

Sean M.Severson

I'm using addflow 4.2 and i want to save the diagram to an array of bytes, i use the save memory function an it returns an ole_handle pointer, i doing this with the next code

Dim DWord As Long, Glblhnd As Long, GlblAddr As Long, R As Long, i As Long
Dim VarAddr As Long, out_Data() As Byte
Glblhnd = FrmTXT.Af.SaveMemory(afAllItems)
GlblAddr = GlobalLock(Glblhnd)
VarAddr = VarPtr(DWord)
Call CopyMemory(ByVal VarAddr, ByVal GlblAddr, 4)
DWord = DWord + 4
ReDim out_Data(DWord)
VarAddr = 0
VarAddr = VarPtr(out_Data(0))
Call CopyMemory(ByVal VarAddr, ByVal GlblAddr, DWord)

it works for an small diagram, but for the big ones it does not work, i think i not getting the right len of the array

Thanks

The fact that you can reproduce the problem with the dummy.ocx control I have sent to you proves that it is not a problem in AddFlow. The problem comes from the fact you use an ActiveX control under .NET and this does not allways work in evry case, especially when dealing with many pictures.
Of course, in the .NET environment, I think that it would be better to use the .NET version of AddFlow.

It's not 100% .NET, Picture converter error on C#.NET, VB.NET

You can associate a picture to a node. As indicated in the help file (the FAQ "How to associate a picture to a node under .NET?"), you can write, for instance:

node.Picture = Microsoft.VisualBasic.Compatibility.VB6.Support.ImageToIPicture(PictureBox1.Image)

Hi!!!
I am using AddFlow component in .NET. Has anybody done DragDrop of nodes. I have a ListView with COM Component name as ListViewItems. What I have to do is - when the user drags and drops the ListViewItem to the AddFlow control area - A node is to created at the drop position programmatically.
Documentation says that the DragOver and DragDrop events (which are necessary to do the above) are automatically added by Visual Basic. I am using C#.NET. C# provides only the DoDragDrop method. Could somebody please let me know how to work around this problem.

Thanks

Hola, deseo trabajar Visual Basic 6.0 con Addflow 4.2 de lassalles, lo que quiero hacer es que cuando presione un botón Command me salga un Nodo pero relacionado con el nodo que seleccione posteriormente, también me gustaría saber cual es el comando para saber si un nodo tiene relación con otro y si son de salida o de entradas, a lo que yo llamo relación son las flechas de unión del diagrama.

Le agradecería que me ayudaran, por favor, o enviaran un ejemplo resolviendo estos problemas, que me hacen tanta falta…

Agradeciendo de antemano franklyn………….(Venezuela)

send me an email. If I cans share some thoughts with you bhafner@siliconmindset.com. I extensivly work with addflow and have found it to be point blank the best activeX control I have ever used (compared against, database, charting, rtf, AI and many others controls). Graph layout is a very tricky area and tree diagrams is just one type of graph that can be done. We have to date created Circle, Orthagonal, semi- orthagonal, hierarchical, symetrical, tree (as in Org charts), Visibility representation and planar algorithms. While we are not ready to part with these (very expensive to develop) I can point you in the correct direction to get going with your project.

PS We use component source almost exclusively. If you are new to the service than let me add - it can't be beat.
