Getting and setting number of series and values

[User (Legacy)]

Hi, 

I am evaluating ChartFX 98 (through the downloaded CfxIEDsgTrial.exe) for 

use in MS Visual C++ application.  I have added it as an ActiveX component 

letting the wizard to create all the wrapper classes.  I am using the 

ActiveX component in a dialog box.  I have created a member variable for the 

ActiveX control in the class associated with the dialog box and using it to 

access all the methods. 

At the design time, the default number of series = 2 and number of points = 

5.  I am reading in data from a file (not using Data Provider, but using 

simple opening the file and reading in the values into an array).  I want to 

dynamically set the number of series and number of values (points) depending 

on the size of the array.  I am trying to use GetNSeries,SetNSeries, 

GetNValues, and SetNValues methods.  Here is the code I am using. 

 long rows,cols; 

 rows = m_fxdlg.m_chartfx.GetNSeries(); 

 sprintf(temp,"No. of Series: %d",rows); 

 MessageBox(temp,"Series ",MB_OK); // displays 2 - OK 

 m_fxdlg.m_chartfx.SetNSeries(nNumSamples);  // Should set the number of 

series = 11 as nNumSamples = 11 

 cols = m_fxdlg.m_chartfx.GetNSeries(); 

 sprintf(temp,"No. of Columns: %d",cols); 

 MessageBox(temp,"Columns",MB_OK); // does not reach this statement 

Running the debugger and getting into SetNSeries fuction, I can see that the 

value 11 is being passed.  However, the invokehelper function generates an 

exception in WINCORE.CPP file.  The exact code that is generating the error 

is 

 CATCH_ALL(e) 

 { 

  lResult = AfxGetThread()->ProcessWndProcException(e, 

&pThreadState->m_lastSentMsg); 

  TRACE1("Warning: Uncaught exception in WindowProc (returning %ld).\n", 

   lResult); 

  DELETE_EXCEPTION(e); 

 } 

 END_CATCH_ALL 

What is happening here?  Please explain in sufficient detail as I am fairly 

new in using ActiveX components in Visuall C++ applications. 

Thanks,
