First time that I encounter this problem. My system imply to communicate with Excel. The dll collection that I was using failed after an update and I had to replace them with an Older collection ElExcel.dll.
Code will work well if each charts is open in one instance, but failed if more charts using the same dll code opened under the same instance
Is there a way to detect a multi instance session or to prevent any problem with the dll code other than opening individual session.
Hope I'm clear because it is very early ( 3:00 am) and my English is still sleeping
