Base64 Conversion Functions

Previously, files had to be converted to Base64 using external libraries before being sent to the backend. The new functions provide built-in Base64 encoding and decoding capabilities, eliminating the need for external dependencies.

Why Base64?

Binary data (such as PDFs or images) can get corrupted when transmitted over text-based protocols. Base64 ensures safe and consistent transfer by converting binary data into a text-based format.

Function: $$EncodeFileToBase64

The function EncodeFileToBase is a new functionality in TallyPrime Release 7.0 that will allow the developers to encode a file in the provided path to base64 string.

This function Returns, Base64 string if successful else empty string.

Syntax

$$EncodeFileToBase64

Example

[Function: EncodeFile]

Variable    : InputFilePath     : String    : “D:\temp\tnc.pdf”
Variable    : TargetFilepath    : String    : “D:\temp\Base64.txt”

000 : Delete File            : ##TargetFilepath
110 : Open File              : ##TargetFilepath : Text : Write : ASCII
120 : Write File             : $$EncodeFileToBase64:##InputFilePath
130 : Close Target File

Function: $$EncodeStrToBase64

The function EncodeStrToBase is a new functionality in TallyPrime Release 7.0 that will allow the developers to encode the string passed to base64 string.

This function Returns, Base64 string if successful else empty string.

Syntax

$$EncodeStrToBase64

Example

[Function: Encodestr]

Variable    : StrtoEncode    : String    : ‘Test String to Encode’
Variable    : Base64str      : String

100 : Set    : Base64str : $$EncodeStrToBase64:##StrtoEncode
110 : Log    : ##Base64str
120 : Log    : $$DecodeBase64Str:##Base64str

Function: $$DecodeBase64Str

The function DecodeBase64Str is a new functionality in TallyPrime Release 7.0 that will allow the developers to decode a base64 string back to string.

This function Returns, String decoded from passed base64.

Syntax

$$DecodeBase64Str

Example

[Function: Encodestr]

Variable    : StrtoEncode    : String    : ‘Test String to Encode’
Variable    : Base64str      : String

100 : Set    : Base64str : $$EncodeStrToBase64:##StrtoEncode
110 : Log    : ##Base64str
120 : Log    : $$DecodeBase64Str:##Base64str
