StephenWS Posted October 13, 2004 Posted October 13, 2004 Hello! I need help. I have impoted the AxMSComm Control 6 in MS Visual Studio .net 2003 and am using the control in C#. I tried to open ComPort #4 to receive GPS data through USB. However, I couldnt' open it, everytime, it gave me the following exception: System.RunTime.InteropServices.ComException(0x800A1F45): HRESULT 0x800A1F45 Could somebody kind enough to help me solve this problem? Any suggestion would be appreciated! Regards, Stephen Quote
jdegama Posted July 7, 2005 Posted July 7, 2005 Same Problem I think this exception is not a lot of help. I am writing in C# and when I try to send data out of Com1 and the port is already open I am receiving the same exact message. I would assume that either your Com4 does not exist or is alredy open. Maybe another member has a better idea. Hello! I need help. I have impoted the AxMSComm Control 6 in MS Visual Studio .net 2003 and am using the control in C#.
