CH340 programmer not auto-resetting

Using Arduino Microcontrollers

I got this ust to ttl programmer which doesn't auto reset the arduino uno. Do I need to add something extra?

Got this one from ebay:

In other posts I found the following:

(you need DTR pin connected to one side of a 0.1uf cap, other side to reset, and a 10k pullup on reset). If this isn't wired up, opening serial connection won't reset the '328, and hence the bootloader won't run, and you can't program it.

I kind of understand what I need to add but don't have idea how to wire it, could someone please provide me with an image, I would really appreciate it.

Thanks,

It should autoreset the UNO, DTR is available, I don't know what the button on the adapter is for.

Obviously, the rest of the leads need to be connected as well, I simply diagrammed the DTR to RESET circuit.

(oops typo 104 is 0.1, not 0.01)

My GUESS is that the button pulls DTR low in order to do a manual reset......?
