For convenience, I am hacking the ptpCamGui code to test certain aspects of a child process.
(I will refer to ptpcamGui as AU3).

AU3 calls createConsole() in the DLL to spawn the ptpcam child process.
It creates pipes to it and redirects ptpcam STDIO to itself.
In ptpcam, you read and write using STDIN and STDOUT as usual.
I have some code in ptpcam that is in an endless loop, checking the input buffer for a character every 100 msec using PeekConsoleInput().
When a character is received it continues with the rest of the code.
That works fine in console mode but not with AU3.

First of all, should PeekConsoleInput() still work with a redirected input ?

Even though there is an option to display ptpcam console it is of limited use because its output is redirected.

Is there any way to display debugging info on the ptpcam console ?

The initialization seems to be working principle. Maybe something is still missing in the porting of the A2200. What says the Lualib test script?

You can try to get a connection with the command line program ptpcam.exe. Or you try it with reyalp's alternative PTP client.

I tried a different camera and it works fine.
Does this have live view- if so how do I see it.

No. For live view use the alternative PTP client.

There is no relationship with ptpCamGui.

Double posts are painful. ;)

sorry that was from the alternative PTP client you had mentioned.
My apologies for the double post.

The ptpgui works fine.
However when I unplug it from the computer and try to take a regular picture
it doesn't take a regular picture.  If turns on fine, nand things appear to be workign,but nothing seems to happen when I prigger the shutter.
What do I need to do?
thx

You mean the shutter on the camera?

That does not work when you have a PTP connection and is normal. The PTP connection locks the native capture functions. You can control the camera only via PTP client software.
