AboutKrisztián Pintér Expertise I`m good at database design and programming, using windows API, multithreaded programming, inter-process commucitations, dll-s and packages. I`m experienced with OLAP and SQL. I also have some COM/ActiveX knowledge and component writing skills. Weak sides: internet, multimedia, graphics. Please don`t ask questions that can be easily looked up in the reference manual, or requires hours of debugging, what appears to be your task. Conceptional or methodological questions are the most welcome ones.
Experience I have 8+ years work experience with Delphi. My primary area is Information Systems Programming. With a small team, we designed and implemented large scale Information Systems to pharmaceutical factories and parking companies.
I am using BCB6 & Flashfiler 2, but any advice from Delphi may help.
How can i post and load jpeg images in a database. Any suggestion, trick and third party component would help.
Thanks in advance
Answer hello,
you need a blob field. i don't know the flashfiler platform, but most databases support some long binary or blob or other data type that can hold any arbitary binary data.
in delphi, there is a field type TBlobField to handle such fields. probably the easiest way to work with them are the LoadFromStream and SaveToStream methods. if you want to add image from file, there are LoadFromFile too (and SaveToFile as well).
if you want to show the image on the screen, you will need a TImage, you will need to add Jpeg unit to your project or form's uses section. Once it done, you can SaveToStream to a memory stream, and then LoadFromStream into the TImage.
