Create a PDF from base64binary after calling a SOAP web service

navbeginner

Hi experts,

Can anyone please let me know how to call a asmx web service passing two parameters. The web service call returns a base64binary stream, which I convert into pdf and save at a predefined location

You can use codeunit 1290 to access the SOAP web service. You might have to add a SOAPAction header, change the content type and add http authentication.

You can find an example of how it is used in Codeunit 248.

When you retrieved the answer, extract the pdf data stream from the xml, decode it using DotNet and write it to a file. Search for what you need here in the .NET Framework documentation.

I am really sorry but I am completely new to web service, so if you can provide example of calling an asmx web service and receive the byte string which may precede the above code it will help me a lot.

Did you look at the Codeunits as I told you? If Yes, please ask more specifically about where you got stuck. If not, please note that a forum is not there to do the work for you, it is there to help you when you're stuck. A well asked question in a forum gives some indication as to whether you are lazy or stuck.

And as lubost said, there are many more examples on the net, how to access various kinds of web services in various ways. Just search.

What is a question/problem?

Hi lubost,

Thanks for asking.
I have a series of steps which achieve in NAV. Below I have mentioned them serially.

• I want to call an external asmx we service from NAV by providing couple of parameters.
• Then the web service will return base64binary string.
• After I receive the string I want to save the data as a file in pdf.

Please let me know if I need to provide more inputs.

Hi RockWithNAV!

I tried out with the code mentioned in the blog link as mentioned below


Byte:=Convert.FromBase64String(FileInBigText); //FileInBigText includes scanned file
MemoryStream:=MemoryStream.MemoryStream(Byte);
TempBlob.DELETEALL;
TempBlob.INIT;
TempBlob.Blob.CREATEOUTSTREAM(OutStream);
MemoryStream.WriteTo(OutStream);
TempBlob.INSERT;

File.CREATE(FilePath); //Filepath Includes Path + Name + FileType
File.CREATEOUTSTREAM(FileOutStream);
TempBlob.Blob.CREATEINSTREAM(FileInStream);
COPYSTREAM(FileOutStrm,FileInStream);
File.CLOSE;


But the issue I am facing is calling the web service by passing the parameters and receiving the byte string.

Communication with webservices is widely discussed, search forum.
