VBcodersS.O.S
about Frx and Exe file size
In
some cases, the size of FRX and EXE files is higher than it should be.
These cases only
involve forms with picture-box controls which contain pictures and
These pictures have
been changed at least once (Replaced by a new picture)
This is caused because Visual Basic
saves all binary data (Such as pictures) in the
end of the form's FRX file. Now, If
you change a picture-box's picture property to a new picture the old picture
will not be overwritten, and still allocate space in the frx file.
This problem also effects the
compiled EXE file which saves all the data from the frx file.
In a game is was doing I had to
change the Picture of an image control that contained the
Background image many times.
Findings:
Frx File size: 1.14 MB
Exe File size: 1.83 MB
Then I deleted the Form1.frx file and
set the pictures again.
Findings:
Frx File size: 0.340 MB (340KB
only!!!)
Exe File size: 0.412 MB (412 KB
only!!!)
Conclusion:
After making a lot of changes in a
program you make, and the changes concern binary data (Pictures, Ole container
data) always delete the FRX files and set the properties from squad.
