How can I integrate a ViChar _VI_FAR result[ ] in C#

[stefangue]

I'm trying to use a wrapped VXIPnP Driver in C# .

I need to import the functions of these win32 dll in C#.net, so I call all the methodes with PInvoke.

These calls works for all Methods, except these Methods which returning a Pointer to a Array like(ViChar _VI_FAR result[ ]);

How can I handle these Types in C#;

int pInvokeResult = PInvoke.CmdString_Q(this._handle, cmd_string,ref size,out  result);

[DllImport("device_32.dll", EntryPoint = "device_cmdString_Q", CallingConvention = CallingConvention.StdCall)]

public static extern int CmdString_Q(System.Runtime.InteropServices.HandleRef vi, String cmd_string, ref Int32 size,  out char[]  result);

I'm not familiar with these Types.

Thanks very much.

Hi Stefan,

do you get a specific error message when handling the array?

Which driver do you use exactly and where did you get it from?

Best regards,
