Hy there!
How I am using the Visual Basic 6, I can call only a dlls which contains
DllRegisterServer, but when I want to call a dll written in Visual C++, or
another language, I have to know a dll functions, parameters which a
function requires, and a values which a function returns, ordinal numbers,
etc, similar to the windows api functions.
When using the windows api functions, it is not problem, because I have
installed Windows api viewer, tool for copying the api declarations to vb
code.
But, how to call a dll which is not in the list of the API?
I am using "dumpbin", tool which comes with Visual C++ 6, but I cannot see
what types of parameters function requires, and what types of values
function returns.
The sintax for "dumpbin" is:
Dumpbin /exports eci.dll > c:\eci.txt
By this, I have complete exports from a dll, but I can see only function
names, such as eciSpeakText, eciSetVoiceParam, eciSetVoiceName, etc, but I
cannot see what type of parameters function requires, to convert them into a
vb code, similar to the:
Public Declare Function eciSpeakText Lib "Eloquence\ECI.DLL" (ByVal lpszText
As String, ByVal lAnotation As Long) As Long
Does anyone know any dumping tool for this problem?
