Hello People,

I am struggling to call the MSFL APIs from c#... any help would be much appreciated... I have done the following:

1. created a new class called MSFL and redefined all consts, enums and functions from the MSFL.h file. the functions redefined as follows:

[DllImport("MSFL91.dll", CallingConvention = CallingConvention.StdCall)]
public static extern int MSFL1_Initialize(string pszAppName, string pszUserName, int iInterfaceVersion);

2. if i execute the following logic:

int returnValue;
string string1 = "programName";
string string2 = "userName";
returnValue = MSFL.MSFL1_Initialize(string1, string2, MSFL.MSFL_DLL_INTERFACE_VERSION);

i get the following error:

An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

System.BadImageFormatException was unhandled
  Message="An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)"
