Hi,

I'm using AddFlow for .NET Version 2.3.0.3 to save a xml file from the addflow object and need to save some extra data.

There's a hidden node with the data, but the WriteXMLNodeExtraData event seems to ignore this node, even if I set the Hidden property to false.

Thanks in advance.

AddFlow Link dont stick to node imina89 [Germany] 07-Apr-2010 14:31:34

Hello,

I'm using addFlow for WPF V.1.1.

When I add some nodes and connect them with a link and then move the nodes, the link sometimes doen't stick with the node but just stays where it was (with no more destination/origin node). Is there a property or anything to tell the links to stick with the node? actually should that be default, shouldn't it?

Thanks.

Regards.

AddFlow C# vasco_silva [Portugal] 29-Sep-2009 16:21:57

Hello,

i want to use AddFlow in .NET do to the following: create an interactive diagram that lets the user go through an hierarchy that i have stored in a DB.

So there would be a node for ObjectTypeA another for ObjectTypeB and so on. The user clicks the Node and for every object associated forward to that Node another Node appears. The user should be able for each node by clicking on buttons on the node to make the nodes that are associated forward and backwards to it appear or disappear. I also want to show a panel with information about the object when the user hovers the mouse over the node.

For each node at least 4 different actions, hide it, show its associations below it, show its associations above it, show a panel with info about the node.

Each node would have to have buttons i guess.

Is this possible to do with AddFlow? If so could you point me towards a sample solution with this type of problem. The ones that came with the suite don't address this.

Thank you

I need to select them at right click of mouse, I mean , I need to change the SelectedItems property at right click of mouse. Please tell me any approach to achieve this. Please post a sample code, If possible.

Señores Component Source,

Tengo exactamente las mismas dudas que Sunil, pues nosotros adquirimos Addflow 3.0, y luego Addflow 4.0 para construir una aplicación en la empresa en la que trabajo.

Actualmente queremos migrar la aplicación a .NET (C#), y tengo un código muy mportante en mi aplicación que usa el el método LastUserAction para guardar en la base de datos, lo último que se hizo, y también, aprovechando las bondades de la herramienta, utilizamos las propiedades Key, y UserData tanto para Links, como para Nodes, y ahora ya no existen en la versión .NET.

Puede alguien, ayudarme a ver qué otras opciones tengo a estos tres problemas?

Muchas gracias por su ayuda.

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

RE: AddFlow plassalle [France] 08-Aug-2003 17:37:58

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.

RE: AddFlow lassalle_patrick [France] 02-Sep-2002 13:57:16

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…

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.
