SpRegistry

• Mode 1: Setting single value.

Syntax: result = spRegistry ( key , name , val , [ type ] ) • Mode 2: Setting default value of a certain key. Syntax: result = spRegistry ( key , [ 'DEFAULT:' ] , val ) • Mode 3: Querying single value. Syntax: result = spRegistry ( key , name ) • Mode 4: Query default value of a certain key. Syntax: result = spRegistry ( key [ , [ 'DEFAULT:' ] ] ) • Mode 5: Query type of a single value. Syntax: result = spRegistry ( key , [ 'TYPE:' ] , name ) • Mode 6: Deleting a single value. Syntax: result = spRegistry ( key , name , 'DELETE:' ) • Mode 7: Deleting default value of a certain key. Syntax: result = spRegistry ( key , [ 'DEFAULT:' ] , 'DELETE:' ) • Mode 8: Deleting an key and all associated subkeys and values. Syntax: result = spRegistry ( key , 'DELETE:' ) • Mode 9: Querying names of all values associated with a certain key. Syntax: result = spRegistry ( key , 'VALUES:' , 'stem' ) • Mode 10: Querying subkeys of a certain key. Syntax: result = spRegistry ( key , 'SUBKEYS:' , 'stem' )

Parameters: key – Registry key. name – Name of the value to be set, queried, or deleted. val – Value to be set, queried, or deleted. stem – The result of the enumerating operations will be set into this stem veriable. Returns:

• For successful setting invocations, result will equal . (1,2)
• For successful querying invocations, result will be given the value of the specified registry value. (3,4,5)
• For successful deleting invocations, result will equal . (6,7,8)
• For succesful enumerating operations, result will be number of items returned. (9,10)
• Possible types returned by mode 5 are 'dword:' (2 byte values), 'hex:' (variable length binary data), (variable length strings).

The error string 'ERROR:' may be returned if an error occurs. Additionally the Variable 'RC' will be set to the return code of the failing API Call.

Return Codes of common failure situations:

• 3 File Not Found (Key not found)
• 1010 Bad Key

Remarks: When setting a value of a non existing key, the key will be created.

Example Code:

/* regdump.cmd (spUtils Example Code) */
/* Prints out a registry key with all values and subvalues, like the */
/* Registry Export function of Regedit */
