Automation error (-2147418107)

Hello, i am having an Automation Error (-2147418107) when using a FlowChartControl in a Visual Basic class module. My problem is that i can't exactly figure out where the problem is. The error happens when i try to select some items with the mouse by drawing an rectangle around the items. The first time(sometimes more) it seems to be working without any errors, but then the Automation error will pop up. Thanks in advance
Sunny

Hi,

Do you handle any events related to changing the selection?

Hi, yes in deed we do. Are there any we should be careful with? We use following event:
DragDrop
DragOver
MouseDown
MouseMove
MouseUp. But what i suspect is the FLOWCHARTLibCtl.table, because everytime you draw a frame across it, starting outside of the table the problem occurs.

Could you email me your compiled .exe file - we'll step through the flowchart code to see what might go wrong.

Hi,
i guess this would be a problem since our application has a lot of references to other own build .dll's. Would a crash dump be helpful?

Please send me the dlls too, or even better an MSI installer package.

hi, sorry i can't. But here a part of the WinDgb which might be helpful:
(f50.97c): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
eax=00000000 ebx=052c3119 ecx=052c8290 edx=0565cf38 esi=052c2ac8 edi=052c4e30

cs=001b  ss=0023  ds=0023  es=0023  fs=003b  gs=0000             efl=00010206

I don't have any idea what to do with that trace. What programming language are you using for this application? If it's C++, make sure you don't Release() the reference count of some diagram item more times than you AddRef() it. That would free the item memory, even if the flowchart still holds a reference to the item, which could result in an AccessViolation.

I think the problem comes from the DoEvents call in SelectionChanged event handler, but I cannot build the project to verify that.

The problem is that the flowchart does not expect to handle any Windows WM_* messages before the WM_BUTTONUP handler exits. Calling DoEvents from the SelectionChanged event makes Windows call the message processing methods for a bunch of WM_PAINT and other messages, and that causes a problem when the WM_BUTTONUP handler hasn't returned yet.

So try running that without the DoEvents call.

Hi,
you are right with the DoEvents, but this problem also occurs if you need to do something in the SelectionChange Event which takes a little bit more time like getting the selected Items and then setting the toolbar and then setting the Properties in a Properties Window.

Probably your methods that set the toolbar or the properties in the Properties Windows call DoEvents too?

i checked it, no the functions don't use DoEvents. The only thing that could be a problem is that  we try to set the active table on top (ZTop).

This works fine in my test project:

Private Sub fcx_SelectionChanged()
    If Not fcx.ActiveTable Is Nothing Then
       fcx.ActiveTable.ZTop
    End If
End Sub

Maybe the property list control that you use calls DoEvents?

Hi, this is out of my control, but if there are any RaiseEvents the application would surely crash on the first run, right? But most of the time it takes more than one time to crash the app.
