Hi friends,

Here is my tiny example modifying the icon of an executable. The technique is based on using memory templates extracted from compiled resource files. To get the binary resource file (rsrc.bin), I used the res2bin tool.


1.Check the "msgbox.exe" file in the attachment. Look at the icon.
2.Now, run the "update.exe" file, you will notice that the icon of msgbox.exe is updated!

Nice example!

it's not work on my XP Pro

Hi jekyll,

My example runs on Win XP He Sp1a, it should run also on Win XP Pro.

Before running updaterc.exe, have look at the icon of msgbox.exe, you will see a "funny face". Now run updaterc, you will see that the "face" becomes a blue colored bug!

It works on my WinXP Pro Sp1...

Hi, Vortex!

It's not work!!!!!
Try 1:
Start 'MsgBox.exe' and not close it;
start 'updaterc.exe'
Your program create temp file on my disk named 'rcxNN.tmp', where NN is hexadecimal number. and if run 'updaterc.exe' once more it create new 'rcxNN.tmp'. GetTempFileName? files 'rcxNN.tmp' was not deleted after 'updaterc.exe' was closed.

Try 2:
start 'msgbox.exe'; close it;
start 'updaterc.exe' it create file 'rcxNN.temp', than delete it!
nothing happens!

Try3:
do try 1 than rename file 'rcxNN.tmp' to executable file; start it - ICON CHANGE.

But i think program must rewrite 'msgbox.exe'.

Hi jekyll,

All you need to do is to run updaterc.exe without running msgbox.exe

it works on my xp pro sp1

Hi, Vortex!

Some strange thing. I run updaterc, than i run msgbox - icon change ok. i delete directory containing this example, than i run msgbox under archive program - icon old. But when i unpack it and run - icon new! Funny!

Hi jekyll,

Glad to learn that you are O.K with my example program, just don't try to run it from the unzipped file as it may give unpredictable effects.

Another method of updating resources is to use a resource linker:
