[VB6] VBCDeclFix - The Add-in allows you to use Cdecl functions in VB6 IDE.

[The trick]

Update.

Added support for CDecl keyword. Now you can use it in the Declare statement like:

Option Explicit

Private Declare Function snwprintf1 CDecl Lib "msvcrt" _
                         Alias "_snwprintf" ( _
                         ByVal pszBuffer As Long, _
                         ByVal lCount As Long, _
                         ByVal pszFormat As Long, _
                         ByRef pArg1 As Any) As Long
Private Declare Function snwprintf2 CDecl Lib "msvcrt" _
                         Alias "_snwprintf" ( _
                         ByVal pszBuffer As Long, _
                         ByVal lCount As Long, _
                         ByVal pszFormat As Long, _
                         ByRef pArg1 As Any, _
                         ByRef pArg2 As Any) As Long
Private Declare Function wtoi64 CDecl Lib "msvcrt" _
                         Alias "_wtoi64" ( _
                         ByVal psz As Long) As Currency
                         
Sub Main()
    Dim sBuf    As String

    sBuf = Space$(255)
    
    Debug.Print Left$(sBuf, snwprintf1(StrPtr(sBuf), Len(sBuf), StrPtr("Test %ld"), ByVal 123&))
    
    Debug.Print Left$(sBuf, snwprintf2(StrPtr(sBuf), Len(sBuf), StrPtr("Test %ld, %s"), ByVal 123&, ByVal StrPtr("Hello")))
    
    Debug.Print wtoi64(StrPtr("1234567"))
    
End Sub

So from now on, the community can use C libraries
