Hi all developer, need advise and help from all.
I'm writing a program, using the Nokia PC Connectivity API, to copy files from my phone to PC and while the copying is in progress, I want to show some progress status in form of progress bar.
Have checked through the connectivity API and found some API that can register a callback function, so that during the copying, the callback function will be called at some regular interval and progress status will be returned.
I have implemented this API in my program, can be built successfully, but at runtime, the callback function is not being called at all. I have even put some message box at the first line of the callback function, but the callback function is not being called at all.
Anyone have encountered this issue or know how to get the callback function to be called? Anybody can advise? Thanks in advance.
