Hi Abhinov Here's the next [url removed, login to view] autoruns when machine is powered on. Full screen form shows Internet connected/disconnected, Camera connected/disconnected icons. Networked folder connected/disconnected icons. When all the states are true it loads the splash image for 5 seconds. Then the camera preview form. I will provide the splash image. Create the camera preview form. Large picture preview window with 6 digit label at the bottom of the screen. Create another program called "EOS Rebel T5i" this will be used to test on your machine as you cant use the canon software. When a space bar keyboard key is received on this software it takes a photo image from a folder of sample images and moves it to the PreviewPhotos folder. This simulates the canon software. When the software detects the image in its folder /PreviewPhotos it displays the image in the preview window, displays its 6 digit file name in the preview label and duplicates the file to the folder /Photos. Add button function to the preview window. This when pressed sends a spacebar keypress to the EOS Rebel T5i program. I used AppActivate and sendkeys for this. Connected icons on the preview page to notify if any state changes.
