Hasp (Function)
In French: Hasp
Interrogates an electronic HASP key (HASP-3, HASP-4, MemoHasp or NetHasp). Hasp is used to protect the applications developed in WINDEV or WEBDEV by Hasp keys.
Notes:
  • To use Hasp, you must be familiar with the operating mode of Hasp keys and have the relevant documentation.
  • Hasp is not available in 64-bit mode. We recommend that you use the HaspHLxxx functions.
Example
// Test for reading the cell 10 of key:
// the numbering starts from 0
FuncNum = 3 // READ_WORD function
Int1 = 10
Hasp(FuncNum, SeedCode, Lpt, Pass1, Pass2, ...
&Int1, &Int2, &Int3, &Int4)
IF Int3 = 0 THEN
Info("Content address memory 10 of key>" + Int2 + "<")
ELSE
Info("Error: return code = " + Int3)
END
Syntax
Hasp(<FunctionNum> , <SeedC> , <LPT> , <Pass1> , <Pass2> , <Int1> , <Int2> , <Int3> , <Int4>)
<FunctionNum>: Integer
Number of the HASP function to run:
  • 1: Checks the HASP key.
  • 2: <SeedC> is used to run a program in the key that will return 4 different integers for each value passed. This is used to check the presence of key and whether it is not simulated.
  • 3: Read the key content.
  • 4: Write the key content.
  • 5: Returns the key content and information about the parallel port.
  • 6: Returns the key identifier.
  • 50: Reads a block of data in the key.
  • 51: Writes a data block in the key.
For the functions used to read and write a fixed string (Str) in the key: <Int3> = 0, <Int4> = &Ch.
<SeedC>: Integer
Used only if <FunctionNum> = 2.
<LPT>: Integer
Port number. If <LPT> = 0, Hasp seeks the key on the "proper" parallel port (without having to specify its number).
<Pass1>: Integer
Parameter supplied by the manufacturer of the key. This parameter guarantees the security of the data stored in the key.
<Pass2>: Integer
Parameter supplied by the manufacturer of the key. This parameter guarantees the security of the data stored in the key.
<Int1>: Integer
Value passed by address (with the & operator). These values can be read in input and/or modified in output.
<Int2>: Integer
Value passed by address (with the & operator). These values can be read in input and/or modified in output.
<Int3>: Integer
Value passed by address (with the & operator). These values can be read in input and/or modified in output.
<Int4>: Integer
Value passed by address (with the & operator). These values can be read in input and/or modified in output.
