Rapi.dll / OpenNETCF Invoke example

Question

I'm failing to use the Invoke method of the OpenNETCF Rapi.dll. Can somebody please post an example? I can't seem to find one anywhere on the web. Other function calls worked fine, but I couldn't figure out Invoke. (dllPath was OK)

MyDll is in the root of the CE device.
It has a FindAndKill method which needs one string argument

I've tried this:

var rapi = new CODMrapi.CODMrapi(dllPath);
var encoding = new System.Text.UTF8Encoding();
rapi.Connect();
byte[] inputData = encoding.GetBytes(fileName);
byte[] outputData;
rapi.Connect();
rapi.Invoke("\\MyDll.dll", "FindAndKill", inputData, out outputData);
rapi.Disconnect();

And what's the resulting behavior? What's coming in to your DLL? — ctacke, Aug 20 '13 at 13:09
FindAndKill method in the DLL has a string argument, which is a filename of an executable file. Finds that process and kills it. — Adam Szabo, Aug 20 '13 at 14:43
Yes, but is your DLL getting loaded? Is the method getting called? Is data coming into the DLL? — ctacke, Aug 20 '13 at 16:20
A simple way would be the strategic use of ::MessageBox calls in the DLL. — ctacke, Aug 21 '13 at 13:36
Yeah, did something similar with file creation. The method is not getting called. — Adam Szabo, Aug 21 '13 at 13:55

You need to debug to determine what's happening. Add in ::MessageBox calls to the DllMain and the method to see if the DLL is even getting loaded and if the method is getting called. If they are not, make sure that your method is publicly exported from the DLL and the name wasn't mangled (dumpbin is a good tool for this)
