 How to check if a chart is load ? |

Hello Peter,
Simply I am stuck in a condition which shouldn't be complicated. My program has some lines that are very similar with your VBChartDemo. So, we can use that demo as reference. As you know, you prefer in your demo to have as default a chart load from Form event. This chart is a "Simple Pie Chart" and you use for this the following line:
tvTreeView.SelectedItem = tvTreeView.Nodes("Simple Pie Chart").
After that you call a refresh demo subroutine which does create the chart and, at the end, you resize the chart calling the "layoutCharts" .
My program has not as default any chart load from Form event but I would like to call the "Resize" subroutine only in the case when a chart is load or visible...
So, I am looking for something like this:
"If ChartViewer(..any..).Visible = True ' or ChartViewer(..any..) is load
Call myResize
End If"
My question is: how to detect, at the code level, if a chart is displayed or not ?
I suppose you have already guessed that I work in VB6. Thank you in advance.
Regards,
Daniel |

Hi Daniel,
I think you can use a loop to check if at least a chart viewer is visible, like:
For i = 0 To ChartViewer.Count - 1
If chartViewer(i).Visible Then
Call myResize
Exit For
End If
Next
Hope this can help.
