HI all,

 

I am consuming a rest webservice api which gives me a back an XML reply message , with one of the XML elements a base64 encoded string.

 

This base64 encoded string is a PDF file , which i need to decode and then write as a PDF file in a certain folder.

 

The webservice call works fine , i receive the base64 encoded string perfectly and i when i code to encode the decoded string , i end up having the same string as my initial retrieve. So i know this part works fine.

 

I am stuck at the simple function to write this blob to a PDF file , the PDF file is created with 219 KB , but gives an adobe error when opening.

 

I tried filewrite , filewriteex , with blobs and strings , encodingutf8! , encodingansi! and so on... Not sure what i am missing here ...

 

string ls_historyreport

//ls_historyreport contains the base64 encoded string we receive from the webservice)

 

blob blob_a

CoderObject lnv_CoderObject

lnv_CoderObject = Create CoderObject

blob_a = lnv_coderobject.Base64Decode(ls_historyreport)
           
            
fnr = FileOpen("d:\abc.pdf", StreamMode!, Write!,Shared!,Replace!,EncodingUTF8!)
FileWriteEx(fnr, string( blob_a, EncodingUTF8!))

FileClose(fnr)
            
            fnr = FileOpen("d:\abcs.pdf", StreamMode!, Write!,Shared!,Replace!,EncodingANSI!)
            FileWriteEx(fnr, string(blob_a,EncodingAnsi!))
            FileClose(fnr)
            
            fnr = FileOpen("d:\abc.pdf", StreamMode!, Write!,Shared!,Replace!,EncodingANSI!)
            FileWriteEx(fnr, STRING(blob_a))
            FileClose(fnr)
            
            fnr = FileOpen("d:\abc1.pdf", StreamMode!, Write!,Shared!,Replace!,EncodingUTF8!)
            FileWrite(fnr, string( blob_a, EncodingUTF8!))
            FileClose(fnr)
            
            fnr = FileOpen("d:\abcs2.pdf", StreamMode!, Write!,Shared!,Replace!,EncodingANSI!)
            FileWrite(fnr, string(blob_a,EncodingAnsi!))
            FileClose(fnr)
            
            fnr = FileOpen("d:\abc3.pdf", StreamMode!, Write!,Shared!,Replace!,EncodingANSI!)
            FileWrite(fnr, STRING(blob_a))
            FileClose(fnr)

 

Not 1 of above filewrites works, ok the 3 filewrites in the end are just tests

 

What am i missing here please ?

 

I need more sleep ... I need more coffee....

 

TIA

John
