Hi,
We modified GCL Dialog sample to RT Dialog application.
No error when we build the application, but we got error message "error building a graph - access violation at 401222".
Please advice us.
Thank you.
And below our code.
void CGraph::BuildGraph()
{
realtype rSampleInt, rBarWidth;
int nDir;
int nLineColor[1];
int nSweepColor;
int nLineStyle[1];
int nLineWidth[1];
rSampleInt = 0.10;
nDir = OR_HORZ;
rBarWidth = rSampleInt / 3.0 * 2.0;
nLineColor[0]=C_GREEN;
nLineStyle[0]=PS_SOLID;
nLineWidth[0]= 2;
nSweepColor = C_BLACK;
WRSetLEDControl(0.1, 0.6, 0.04,WGGetRGBColor(C_LIGHTGRAY),1, 2); //ok
// CSpEaaApp *pDoc = (CSpEaaApp *) GetDocument();
// ASSERT(pDoc) ;
// QCDynData *pDataSet = pDoc->GetDataSet ();
// pDataSet->WRGetNumChans();
/*
WRSetSweepGraph(pDataSet, 0.02, nDir, nLineColor, nSweepColor, NO_STEP, nLineStyle, nLineWidth);
*/
WRSetSweepGraph(theApp.pDataSet, 0.02, nDir, nLineColor, nSweepColor, NO_STEP, nLineStyle, nLineWidth);
}

| Help us out. When you trace through the BuildGraph method, where does the error occur? |
