Hi Experts,

I have a requirement wherein I have to convert the saved PDF to Base64. I have written the following code but that doesn't seem to work and there are hardly any blogs regarding it.

Filename := 'C:\NAV\Service Invoices\PSI0000081.pdf';
MyFile.OPEN(Filename);
MyFile.CREATEINSTREAM(IStream);
MemoryStream := MemoryStream.MemoryStream();
COPYSTREAM(MemoryStream,IStream);
Byte := MemoryStream.GetBuffer();
locOutFile.ADDTEXT(Convert.ToBase64String(Byte));
MESSAGE(FORMAT(locOutFile));
MyFile.CLOSE;

Can anybody suggest me how than can be done or where did I go wrong? Your suggestions are welcomed.

Thanks in advance.

RE: Convert PDF to Base64 using OutStream

You can use File Management codeunit and TempBlob record

FileName := 'C:\NAV\Service Invoices\PSI0000081.pdf';

FileManagement.BLOBImportFromServerFile(TempBlob,FileName);

MESSAGE('%1',TempBlob.ToBase64String);

Since you are using MESSAGE prompt , try to convert PDF file with size smaller than 20 KB since the converted base64 text can be too long and cannot show in message prompt.

Alternatively save the base64 text in blob field or text file instead.
