Hi Frank, 

query->Active = true; 

Varian v2 = (long) query->Handle; 

ChartFX1->GetExternalData("CfxData.BDE",v2); 

ChartFX1->DataEditorObj->SizeToFit(); 

Both, query and code work very well if I execute it from a TForm within 

one EXE project. But, if I try to execute it from a TForm within one DLL 

I get that error, I must even call the CoInitialize function in order to 

see the ChartFX into the TForm. Why calling that function (Coinitialize) 

is unnecessary when the component is living within an EXE? 

The DLL is dynamic loaded, and in order to avoid Windows displays two 

applications in the taskbar I change the DLL's TApplication for the 

EXE's TApplication. 

Thanks a lot, 

Marco
