Hi,
I want to save user layout preferences in a database to use in the next program execution. For this I'm saving the result of SaveLayoutToString. In the next execution the initial layout is the original, and then I call LoadLayoutFromString. The layout changes like expected, but with empty panes. When I try to reassign the handles the program crashes. Does this have a solution, or do I have to parse the XML and use the relevant values in the CreatePane method? ------------- SuitePro 20.3.0 OS: Windows 10 Language: Visual Objects 2.8 |

That's the way I do it, after I load the Layout from string, the first thing I do is set the handles of the container controls:
For J = 1 To .PanesCount
DockingPaneManager.Panes(J).SetHandle Elastic(J).hwnd Next J then set some other stuff like titles, colors, and pane options. |

Thank you for pulling in 
But I'm not sure if I understand you. Do you re-assign the handles after LoadLayoutFromString, or the first thing you do is loading the layout and only then assign the handles (didn't try this yet)? ------------- SuitePro 20.3.0 OS: Windows 10 Language: Visual Objects 2.8 |

Not sure I understand your question, aren't these two the same thing? Each pane has a container control. After I do ANY Load from string, I have to assign the handles whether it is the first time thru, or if the user is loading in a different layout.

In my case if I load a layout AFTER assigning the handles the panes become empty, and if I assign again the handles the program crash.
I presume you can (re)assign the handles at any time, right? ------------- SuitePro 20.3.0 OS: Windows 10 Language: Visual Objects 2.8 |

| Yes, I have no problem reassigning them multiple times. Using VB6 SP6, and picture boxes as the container controls. I have several preset layouts that the user can load from string. Each time, it loads the layout, then I assign the handles to the panes, then set the titles, color, and pane options. I've never seen it crash, so I assume it is very possible to do. |

You have first define the layout by LoadLayoutxxx.
If LoadLayou doesn't create panes, you can create a default-layout.
To attach the panes, you have to use the DockingPane_AttachPane-Event.
Depending on the associated Item.Id-Property you can than create and attach the corresponding forms/pictureboxes.
Define a unique Id for the type of pane.
The reason is, that LoadLayout destroyes all prevoius created panes and create new panes on the loaded layout.
