Hi,

Recently i have migrated PB 8 to 19 version. In code im getting symbols while converting blob to string.So i have converted to encodingANSI! format in many places.. it is working fine.but in one place im struggling. please help me.

//sItemDIN = string(blobmid(is_source,il_pointer,long(mfieldsize)))

sItemDIN = string(blobmid(is_source,il_pointer,long(mfieldsize)),EncodingANSI!) 

In the above line sitemdin has some symbols while debugging..

 

Regards,

Backya.

PB8 was not Unicode, PB2019 is, that's why you're seeing different results.  Where is the Blob coming from?  Sounds like it's not Ansi data in the Blob.  What type of encoding is the data?  Have you tried any of the other encoding values?

Use FileReadEx directly to a blob instead of FileRead in a loop.
