Calling Windows API ImageViewer.dll to display JPG files.

DMeakin1 — Fri, 17 Jan 2020 19:16:11 GMT

I am working with a very large database of image files and want to be able to display the file for the user for visual inspection from a script.

I have been able to get the following code to load the DLL but get an error requesting a signature argument.

Does anyone know how to get a signature string from the system to pass to the DLL.

ERROR MESSAGE FORM LOG: Second argument to CallDLL must be a signature string. in access or evaluation of 'call DLL' , call DLL( "ImageView_Fullscreen", PATH_TO_IMAGE )

// rundll32 "%ProgramFiles%\Windows Photo Viewer\PhotoViewer.dll", ImageView_Fullscreen path_to_image

IMAGE_NAME = "TEST_IMAGE_1.JPG";
PATH_TO_IMAGE = IMAGE_PATH || "\" || IMAGE_NAME;
Show( PATH_TO_IMAGE );

DLL_HANDLE = Load DLL( DLL_PATH );
DLL_HANDLE << call DLL( "ImageView_Fullscreen", PATH_TO_IMAGE );
