Description marc meumann 2017-09-22 06:47:11 EDT 
ASP.NET and MVC projects that function correctly on private servers can fail with an IntPtr hdc error caused for image format renders when TeeChart renders as image. This is avoidable by changing the buffer style:

eg.
webChart.Chart.Graphics3D.BufferStyle = Steema.TeeChart.Drawing.BufferStyle.None;


The problem may occur on first load only (when TeeChart is loaded to app memory space once per server's global application lifetime) under Azure due to a designer init code that also provokes the IntPtr error.
