An .FRX file is a binary data file used to store binary information forthe form (.FRM) file with the same file name.
Some controls, such as the PictureBox and Image controls, have propertiesthat use binary data as their values. Visual Basic stores the binary datain an .FRX file with the same file name as the Form file. The .FRX file isa proprietary format.
If your project contains .FRX files, you should include these files withthe corresponding .FRM files. A form containing binary information butlacking the associated .FRX files will not function correctly.
For a good description of what the .FRX file is and how it works, pleaserefer to the Binary Property Values section of the Appendix A: Form andProject File Formats chapter of the Programmer's Guide.
