Error: PlatformNotSupportedException


Licensed User
I have a user that reports the following error:
get a message saying "Basic4ppc. Error loading program. PlatformNotSupportedExecption"
He reports he is using a Dopod 818pdo (aka Prophet, I-mate JamIn, Qtek S200, XDA neo) running WM5.

What is the meaning of this error?

I'd like to activate this old thread because of a similar problem. This little program throws the same exception when running on my HTC HD2 with Windows Mobile 6.5 (.NET CF 2 in ROM, .NET CF 3.5 also installed):

Sub App_Start
End Sub
response is a WebResponse of HTTP.DLL, and the program is running fine on the PC (Windows XP). What could be wrong? I tried many things to get a webpage containing German characters (ä, ö, ü, ß) and save it into a html-file, and after hours I found a solution on the PC which needs response.New2. Unfortunately, the mobile version throws PlatformNotSupportedException. It is not possible to call New2 on the mobile device.

Did you try with 1252? Me too I've this problem (Je suis français :)) but never solved...
I think there's a function who convert these charactere in C# but I don't remember...
But with ByteConverter.dll there's no functions about this?
