Display the code of the "Validate" Button control: • Select the "Validate" Button control. • Press F2. 2.  In the "Click (server)" event, add the following code AFTER the call to PageToFile : IF gsImagePath<>"" THEN Product.Visual = fLoadBuffer(gsImagePath) END 3.  Let’s take a look at this WLanguage code: • This code checks the content of gsImagePath global variable. If this variable does not correspond to an empty string, it means that the image was uploaded by the user. In this case, the "Visual" item of Product data file is filled with the binary image content. This content is retrieved by fLoadBuffer . • HModify (already found in the code) is used to save the changes in the data file. 4. Save the modifications ( or Ctrl + S). 5. Close the code window.
