Type Library

QHASH_FileDigest

Return value

Parameters

nAlgID

    [in] The ID of the hash/checksum algorithm selected for calculations. For example, nAlgID has to be set to SHA1_ALGID when you need to calculate the digest using SHA-1 hash algorithm.

    Note. All supported hash/checksum algorithms with their corresponding IDs are specified in the Predefined Constants List.

 pDigest

    [out] The memory buffer that will receive the message digest/checksum.

    Note. All predefined types are specified in the Predefined Types List.

 pszFileName

    [in] A null-terminated string specifying the name of the file for which to calculate the message digest/checksum.

Remarks

Calculates the message digest/checksum for a file. The digest/checksum is retrieved in the pDigest memory buffer.

VB Example

Private Sub MyButton_Click()

    Dim Digest As QHASH_Digest

    'Calculate the digest 

    QHASH_FileDigest MD5_ALGID, Digest, "C:\Test\Test.txt"

    'Show the hexadecimal representation of the digest

    MsgBox QHASH_ConvertToHex(Digest.Value(0), MD5_DIGESTSIZE, True)

End Sub
