JK Patcher & CogExt.dll

---

For whatever strange reason, I cannot get self-extracting zips/rars to work right when JK Patcher is compiled. It might have something to do with them not returning a process ID, or the program locks the file or some crap. It works fine in the VB Development Environment, but refuses to when compiled, even if I use a .bat file! JK will run FINE, but not my self-extracting updates! >_<!!!! I tried all sorts of alternative methods to no avail.

So, I tried seeing if I could find some code to extract zip files in a VB program. Found a few hits, implementation however was not so hot.

So now I'm up to suggestions. (HELP WITH THE SOURCE OF MY PROBLEM WOULD BE KEEN!!) I want to deliver updates of cogext.dll, jk.exe patches, and JK Patcher in as tiny a filesize as possible, without using self extracting zips or, uh, any compression whatsoever. >_<

They Don't Work: The self-extracting zip/rar .exe files never get executed, therefore, never extracting the sweet goodness from within.

I've been having a debate in my head and with JKSERVER about VB and the filesystem.

I want to believe that when VB closes a file, the next line of code doesn't execute till the filesystem is done closing/writing/copying/etc the file. JKSERVER believes that VB continues on after a filesystem related command, and doesn't wait for the filesystem to finish with the file.

I've tried putting in timers and sleeps and whatever to see if indeed the filesystem just needed to catch up, and it appears JKSERVER is parinoid. (afaik ) My self-executing files just won't get ran no matter what I try. I even decided to try something like this:

DownloadFile(Blah blah) 'Works fine, file is created, execution returns when file is 100% done RunProgram(FileExe) 'This function has been rewired so many times, it's not funny.  I did however come across one that would run JK properly. On Error Resume Next 'You'll see why FileCopy ExtractedFile, FileDestination 'Copy file while Err = 53 'File not found DoEvents 'do crap in the bg FileCopy ExtractedFile, FileDestination 'copy it wend

That SHOULD have made it wait till the filesystem 'caught up' if that was the case, but it just made JK Patcher go into an infinite loop. (Meaning the self-extracting never took place)

Ideas?

I FIIIIIIIIIIXED IT!

It seems to have been a problem with the self-extracting .exe and executing it properly. A simple ChDir App.Path, followed by Shell "UpdateName.exe" made them run and extract the goodness within. Then I just have a loop trying to copy the file with some error trapping. While Err=53, copy file, wend.
