Hi Gang!

This is a continuation of a thread I started earlier......

I have a dotNET DLL called RBA_SDK_CS.dll that was thrown at us to use..... (without consultation of course). This dll is to interface between our FOXPRO app and an Ingenico Credit Card swipe and signature pad.

Unfortunately, I cannot access the methods, properties or events of the dll in VFP (sigh...).

So, I can use Rick Strahl's wwwDotNetBridge to try and access the dll and use it.

I can do this so far with the dll...
CLOSE ALL
CLOSE DATABASES
CLEAR DLLS 

do wwDotNetBridge
PUBLIC loBridge as wwDotNetBridge
loBridge = CreateObject("wwDotNetBridge")

PUBLIC loRBA as Object

loBridge.LoadAssembly("RBA_SDK_CS.DLL")
loRBA	= loBridge.CreateInstance("RBA_SDK.RBA_API")
lntest	= loBridge.Invokemethod(loRBA, "Initialize")
But now I need to be able to do this C# line of code...
var CommSet = new SETTINGS_COMMUNICATION();
where the SETTINGS_COMMUNICATIONS is a type of STRUCT.

and here are the STRUCTS properties..
CommSet.interface_id = (uint)COMM_INTERFACE.SERIAL_INTERFACE;
CommSet.rs232_config.ComPort = "COM8";// cmbCommPort.Text;
CommSet.rs232_config.BaudRate = 115200;//Convert.ToUInt32(cmbBaudRate.Text);
CommSet.rs232_config.DataBits = 8;//Convert.ToUInt32(cmbByteSize.Text);
CommSet.rs232_config.Parity = 0;//(uint)cmbParity.SelectedIndex;
CommSet.rs232_config.StopBits = 1;//Convert.ToUInt32(cmbStopBits.Text);
CommSet.rs232_config.FlowControl = 0;//(uint)cm
I saw in some online discussions where Rick uses this to access STATIC PROPERTIES....
*** Retrieve a static property which is an object
 loConfig = loBridge.GetStaticProperty("Westwind.WebLog.App","Configuration")

 *** I could also instantiate the config object directly
 *loConfig = loBridge.CreateInstance("Westwind.WebLog.App")
I tried some variations of this, but I could not get the loConfig to instatiate... I keep getting .NULL. for it and the error message returned is

"Type not loaded. Please load call LoadAssembly first"

So, can anyone help me, please? My job is on the line here ...... ( time to learn C# for real now, I guess.... sigh...)

attached is a screenshot of the DLL in the object browser of Visual Studio

Thanks!
