The functions contained in the DLL file are shown here. For example: Draw numbers from an esoffice number group (ESoffice.GetNextNum).
Assembly ESTRansferr.ESO.dll
ESTransfer.ESO.DLL is copied into the esdbm program directory when esdbm is installed, so it can be incorporated into a transfer using the Assembly function.
The following functions can be addressed through the Call function in a transfer:
ESoffice.GetNetNum
Draws the next free number from an esoffice number range.
ESoffice.GetImage
A directory path or an URL can be applied to this function by means of a variable.
The ESOffice.GetImage function opens the images and converts the images (possible formats: jpg, jpeg, png, bmp, tif) into a database format valid for esoffice and enables import of these images.
ESoffice.ExtractPNG
You can convert images saved in the esoffice database in esDBImage format into PNG image files (*.png) that can be read by all systems.
