Hello,
Though I am not putting in the exact code, but some guidelines are there, using these, you may make a search in MSDN to find the exact 'TYPE SIGNATURE' i.e. function definitions :
1. Data can never be sent to a DLL that way. A DLL is already loaded in memory as a shared library, you can access it.
2. To do so, place the DLL in the project file (.vbp) 's directory itself.
2. Use the Declare command to declare the functions in the DLL to VB.
3. Call these functions using exact parameters needed.
4. Take care of whether ByVal (by value) or by ByRef ( By reference).
5. Using the function, you may pass the values, and get the encrypted data. Maybe the function in the DLL was written as a C-function. Is it?

Bye.
