DLL interop / interesting error

char ARRAY[1024]; // <-- global

Code below works

myFunctionInDll("some string"); // everything ok

Code below doesn't work

myFunctionInDll(ARRAY); // after compilation the entry point of DLL cannot be found

So, to sum up, if I pass a "static string" to my function inside my dll the dll compiles and loads perfectly. However, if I populate the global array (chars) and then try and pass that to my function, again it compiles but when I try and call the function from my C# app I get 'entry point cannot be found.' This is really strange and I can find no reason why...

Thanks RU.

Anyone know why?

Did you write the interop or are you just using the .NET generated interop class? If the later try

string myStr = "some string";
myFunctionInDll(myStr);

Hope that helps.
