GetPicture and leak of GDI objects

[User (Legacy)]

Hello

When I call GetPicture in the ChartFX then I see GDI objects leak. Why?

(if I pass parameter as CHART_BITMAP then 1 GDI object per time if I pass

parameter CHART_METAFILE then 2 GDI object per time )

Can you offer me any work around?

PS I use Chart FX Client Server ActiveX Control (version 5.0.9)

example of my code ;-)

        Private Sub Command1_Click()

            ChartFX1.GetPicture CHART_BITMAP

        End Sub

Thanks

A Picture Object is created and returned to you. You are responsible, when

you're done with it, to release it.

Hello,

of course, I can write

Private Sub Command1_Click()

    Set temp = ChartFX1.GetPicture(CHART_BITMAP)

    Set temp = Nothing

End Sub

it's nothing change and this is same that previous code...

What should I write that there is no GDI leaks?

Thanks

This looks like a bug, I will have to check further.

A workaround is easy though, call DeleteObject (pic.Handle) after you are

done with it.

Thanks fo your answer.

Your workaround helps avoid GDI leaks when I call GetPicture and pass in it

CHART_BITMAP parameter but when I pass CHART_METAFILE then it doesn't help

and 2 GDI object leak per time. The saving as bitmap gives low qualities of

bitmap therefor I can't use it. I try using Export method and save bitmap in

the stream ( I read that it's possibly in the documentation ). In my test

project I have done following

CComVariant vt1;

vt1.vt = VT_UNKNOWN;

vt1.punkVal = pStream;// this interface inherit from IStream interface

m_Chart.Export( ChartfxLib::CHART_METAFILE, vt1 );

but Export returns E_FAIL, Where am I wrong?

Thanks

You need to assign VT_STREAM instead of  VT_UNKNOWN.

Because of some checking made by _varaint_t, you will need to use

raw_Export.
