I use a Windows 8 computer for development, and I created a form that brings data from SQL, among the tables there is a "Photos" table that have a FileStream field with a PNG or BMP image (BMP is only there for at first I thought it might have been an issue with png support in windows 7, as I read some threads about it, in the end we are going to only use pngs). In my form I retrieve the photo as needed and change the PictureVal of an image object to whatever is the value in the cursor's photo field. This works perfectly in Window 8 or 8.1 (did not test in 10 yet) but it does not work in Windows 7, for Windows 7 I created an horrible work-around that creates a temporary file and set the Picture of the image object to this created file. The question is: Is there any change that I can make in Windows 7 in order to make this thing work using PictureVal directly as in Windows 8? I seem to recall that this issue was discussed here, but I might be wrong.

TIA

[PS]
Interestingly enough, I just remembered we still have one Windows XP computer so I tried the program in there and PNGs do not work, same as in Windows 7, but BMPs DO work!
