PictureButton control

A PictureButton displays a picture and, like a CommandButton, is used to carry out an action. For example, you can use a button with a picture of a file to save a file, or a button with a picture of a stop sign to cancel a requested deletion.

The picture image can be in the following formats:

  • Bitmaps, with .BMP or .RLE extensions

  • Windows metafiles, with the .WMF extension

  • GIF or animated GIF files, with the .GIF extension

  • JPEG files, with .JPEG or .JPG extensions

  • Portable Networks Graphics, with .PNG extension
