A very simple code, but a "type mismatch" error occurred. Please ask for help from experts!
The code is as follows：
Code: Select all
void Cteechartdemo2Dlg::OnBnClickedLine1()
{
// TODO:
CSeries lineSeries = (CSeries)m_Teechart1.Series(0);
lineSeries.Clear();
for (int i = 0; i < 50; i++)
{
lineSeries.AddXY((double)i, rand(), NULL, NULL);
}
}

After tracking and debugging, it was found that this error (COleException cause. code=80020005) should be resolved?

Hello,
I'm not sure what exact line of code is giving the error in that screenshot. However, if we assume there is a Line series in the Chart, I think that code should work.
If you still find problems with it, please arrange a simple example project we can run as-is to reproduce the problem here.
