Im developing a in-house project for serial transfer of some text files,which are read by the connected machine into operating recipes.
To make it easier for the operator, ive laid the front end out all nice so that they can use a touch screen panel.

However, because i dont know any better, ive used the common dialog control for when they click on the "select recipe" button. A standard window opens up and they can then select the correct file.

The window that opens up is too small, and the icons that show up are also too small for them to select the correct one by touching the screen.

Ideally, i would like this window to open up maximised, and id like the files within it to open up as thumbnails. This would give our operators plenty of room to press the correct file for downloading into the machine, without fear of selecting the wrong one.
I have figured out how to point the control to the correct directory
commondialog1.initdir = "C:\*****"

but i cant see the expected
commondialog1.maximise
or
commondialog1.arrangeicons = thumbs
(i know these dont exist, but just to give you the idea of what i want to do)

Everyone i have spoken to says that the common dialog control is too limited for this, and that i would be best to make up my own recipe select form where i could have total control of layout and font size etc.

Before i do this, (and i dont have clue where to start, so it will take me a while) i thought i would post a thread here, to see if anyone out there had seen or heard of a way of maximising the common diaglog box, and laying the icons as thumbnails
