Chris,

Thanks for an awesome utility. I was wondering whether PixelSearch could be done in "reverse" mode, i.e. starting from the lower right corner of the rectangle and scanning to the upper left corner. Maybe add another parameter to the PixelSearch function (i.e. 1=default upperleft-to-lowerright, 2=lowerright-to-upperleft)?

Just a thought.

Thanks.

Although I can see why that would be useful in rare cases, it doesn't seem common enough to justify adding another parameter to the already-long list of parameters for this command. Has anyone else ever felt a need for this? Note that you could create your own reverse-search subroutine that mirrors the functionality of PixelSearch. You could also search smaller subregions with PixelSearch to give precedence to the lower right quadrant.

Thanks for the explanation. It might be helpful to know that nearly all tray-icon based apps have a hidden main window that can be displayed with WinShow. Once displayed, you can usually access most of that app's functionality from its menus or buttons. Also, you might try running the app a second time, which sometimes causes its window to appear (it might even offer command line paramters to do certain things).

If that doesn't work, another thing you can try on Windows XP (but this is a longshot/crazy idea) is sending Win-B, which activates the system tray. Then send a series of {right}'s to get to the correct icon, then send {AppsKey} to open that icon's menu. If the menu in question has a unique shortcut key (underlined letter), you could press that key on each icon's menu until the correct window or function is activated.

Finally, a trick I use to uniquely identify images is to find two pixels that are likely to be unique for that icon. Then do a loop to find each occurrence of the first color. For each occurence, check if the second signature pixel occurs at the correct relative position to the first. If it does, you have a match.

Someone sent me the source code for an ImageSearch function which I hope to try out soon. Basically, it searches the entire screen for a particular image.

Edit: The suggested reverse-PixelSearch is now supported.
