Convert PDF stream to Base64String in D365FO

Posted on by Sangeeth R

Hi Folks,

We are trying to convert PDF stream to Base64String, in order to share the encoded Base64 string with other 3PL system.

Note: We don't have file as input, we are getting this PDF Stream from class (ERFileDestinationAttachment) while system execute ER (BDM) report.

It wasn't working when this feature is enabled /Utilize application resources to perform CBD documents conversion from Word to PDF format/ under feature management.

Requirement scope: Convert PDF stream to Base64String

Logic 1:

System.Byte[] bytes;
System.IO.BinaryReader binaryReader;
System.IO.Stream baseStream;
System.IO.StreamReader streamReader;
System.Object streamObject;
System.Object bytesObject;
int streamLength;
int bytesLength;

baseStream = _pdfStream;
streamObject = baseStream.get_Length();
streamLength = streamObject;
binaryReader = new System.IO.BinaryReader(baseStream);
bytes = binaryReader.ReadBytes(streamLength); // Here system return as bytes[0]

baseStream.Close();

bytesObject = bytes.get_Length();
bytesLength = bytesObject;
base64data = System.Convert::ToBase64String(bytes, 0, bytesLength);

Logic 2:

using (System.IO.Stream fileStream = _pdfStream)
{
using (System.IO.MemoryStream memoryStream = new System.IO.MemoryStream())
{
fileStream.CopyTo(memoryStream);
base64data = ERConversionUtils::StreamToBase64(memoryStream);
}
}

For conversion from PDF Stream to BASE64String

If Feature is enabled,

Both logic 1 & 2 - Not working

if Feature is disabled,

Both logic 1 & 2 - Working

Note: We had to enable this feature, since we are trying to print/save document which has more than 300+ lines. As per suggestion from MS.

Kindly advise with some input on this.

Thanks in advance.

Thanks,

Sangeeth

What do you need from us? Can't you simply use the working solution, i.e. enabling the feature?

I don't know what you mean by "not working", bit it's clear that the problem isn't related to the code you showed us above. It seems to be about how you create the PDF. I'm assuming that you use Configurable Business Document (CBD), which the feature is about. Then enabling it makes a good sense.

It's difficult to guess if all you told us was "not working", but it's quite possible that you'll see the problem if you forget your code and just download the file by File::SendFileToUser(baseStream, 'test.pdf'). If so, it's a definite proof that problem has nothing to do with your conversion to a Base64 string.

Hi Martin,

Thanks for reply. Sorry I might not give clear requirement scope.

Requirement scope: Convert PDF stream to Base64String

Technical scope: Receiving PDF stream from D365FO with use of CBD and then sharing BASE64String conversion value to another system.

We use custom service API to get request from another system, then we respond them as Base64String.

So, Logic which using for this requirement was working only when that feature is DISABLED.

Thanks,

Sangeeth

Ah, sorry, I overlooked that it works if the feature is disabled, not enabled.

But the rest of my reply still stands, such as that the problem doesn't seem to be anywhere in the code you showed us.

Hi All,

At last, it got worked for me.

Logic:

str     fileDownloadURL;
            System.IO.Stream        tempPdfStream;
            fileDownloadURL = File::SendFileToTempStore(<Input stream(_pdfStream)>, this.parmSaveFilePath());

            tempPdfStream = File::UseFileFromURL(fileDownloadURL);

baseStream = tempPdfStream ;
streamObject = baseStream.get_Length();
streamLength = streamObject;
binaryReader = new System.IO.BinaryReader(baseStream);
  bytes = binaryReader.ReadBytes(streamLength);

baseStream.Close();

bytesObject = bytes.get_Length();
bytesLength = bytesObject;
base64data = System.Convert::ToBase64String(bytes, 0, bytesLength);

Thanks,

Sangeeth
