BSTR QHASH_FileHexDigest( [ in ] int nAlgID, [ in , string ] unsigned char* pszFileName, [ in ] boolean bUpper );

Return value

The hexadecimal representation of the message digest/checksum.



    [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.


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


    [in] Uppercase flag. If bUpper is False, the received message digest/checksum represents a lowercase string, otherwise it represents an uppercase string.


Calculates and returns the message digest/checksum for a file. The digest/checksum is returned as a hexadecimal string.

Note. If the result is an empty string call QHASH_GetLastError function for the error code.

VB Example

Private Sub MyButton_Click()
    'Calculate and Show the digest in hexadecimal representation
    MsgBox QHASH_FileHexDigest(MD5_ALGID, "C:\Test\Test.txt", True)
End Sub
