Send Image over TCP failed ??

[ganapathi]

Your TCP code suffers from the same problems as your UDP code, which I pointed out in your other thread: strange global variables such as "a" and "img_block" are being modified all over the place, the "y" counter in a for loop is modified inside the body of the loop, etc. Maybe you got it working on UDP, but I wonder how maintainable it is.

Here is one new problem in your TCP code: you seem to assume that after you call socket->write(buffer) in the client, the server receives all this data, and only it, as one nice block, which you can read with socket->readAll(). That is not how TCP works. I strongly suggest you read http://blog.stephencleary.com/2009/0...e-framing.html to understand the problem.

My aim is only to test the concepts than optimize it. Just get it working.

I will go through that link and implement those solutions and let you know further .

Thanks a lot for the link.

Hi,

As yeye_olive explained, you are assuming that the full image will be received in one slot call on the client side. This is not true, so you will receive the image into blocks(data chunks).

My aim is only to test the concepts than optimize it. Just get it working.

This is not a optimization problem, the problem is the concept.

Please, read the link that yeye_olive provided you.
