Description

File2Blb (Magic xpa 2.x)

Moves a file into a BLOB variable.

Syntax:

File2Blb (file name)

Parameters:

File name (Alpha): The name of the file to be converted into a BLOB.

Returns:

BLOB – The file packed as a BLOB.

Example:

File2Blb('C:\myfile.txt') returns a BLOB with the content of the c:\myfile.txt file.

Note:

For a large file, a crash or an Abnormal termination alert may appear due to insufficient memory. When Magic xpa loads a file into a BLOB, it first reads the entire file and then allocates memory to the BLOB variable. This results in a memory consumption that is larger than the file size itself, which may result in a crash or an Abnormal termination alert. If this file needs to be sent to the client, it is recommended to send it using the ServerFileToClient function.

Exceptions:

This function is not supported as a parameter in the Invoke Web Service Lite operation.
